摘要： A conveyor has an endless belt which encompasses a gate section and a fixed section thereof Both the gate section and fixed section have beds which extend lengthwise and widthwise thereof between rails which extend along the lengths of the section. The edges of the belt run along the rails and are hence guarded by the rails. The sections are joined at adjacent edges by hinges pivotally connected to the bed of the fixed section and extending across the joint to the gate section. The hinges are within the confines of the belt, that is within the path of the belt and between the edges of the belt, so as to enable the gate section to be pivoted to an open position allowing a passageway via the width of the conveyor. When in closed position, the hinge enables the ends of the rails to move into abutting relationship. Permanent guards on the outsides of the fixed section can extend above the belt to maintain safe operating conditions without interfering with the opening and closing of the gate section. The endless belt may be made of panels joined together by rods which allow the belt to turn around the outer ends of the fixed and gate sections. The fixed section is equipped with a sprocket in which the rods are engaged for driving the belt. The sprocket is motorized by a drive within a closed housing attached to the rails so that the fixed section serves as a drive section of the conveyor. The belt is not tensioned and is supported on the bed of the sections so that the belt can move and change shape from straight to curved at the hinged joint as the gate section moves from closed to open position. The sections may be mounted on legs. The gate section may be counterbalanced to maintain it in open position. Concealed interlock sensors may be located in the joint for automatically stopping and starting the conveyor when opened and closed, respectively.
摘要翻译： 输送机具有环形带，其包围门部分和固定部分。门部分和固定部分都具有沿着该部分的长度延伸的轨道之间的长度方向和宽度方向延伸的床。 皮带的边缘沿轨道延伸，因此被导轨保护。 这些部分通过枢转地连接到固定部分的床并通过接头延伸到门部分的铰链在相邻边缘处连接。 铰链在带的限制范围内，即在带的路径内和带的边缘之间，以使得门部能够枢转到允许通过输送机宽度的通道的打开位置。 当处于关闭位置时，铰链使轨道的端部移动成邻接关系。 固定部分外侧的永久性保护装置可以在皮带上方延伸，以保持安全的操作条件，而不会妨碍门部分的打开和关闭。 环形带可以由通过杆连接在一起的板制成，这些板允许带绕固定部分和门部分的外端转动。 固定部分配备有链条，其中杆被接合以驱动带。 链轮由连接在轨道上的封闭壳体内的驱动器驱动，使得固定部分用作输送机的驱动部分。 皮带没有张紧，并且被支撑在这些部分的床上，使得当门部分从关闭位置移动到打开位置时，带可以在铰链接头处从直线移动并变形成弯曲。 这些部分可以安装在腿上。 门部分可以被平衡以将其保持在打开位置。 隐形联锁传感器可分别位于接头中，用于在打开和关闭时自动停止和启动输送机。

摘要： A relatively low cost, low friction plastic needle bearing assembly uses a unitary plastic circular member with multiple frangibly attached substantially cylindrical needles axially inserted into a cover. A plastic needle separator housing element provides a race and is in axial registration with the frangibly attached needles. A shaft (on which a sprocket of a web feed device or tractor is mounted), upon axial insertion through the member to which the needles are attached, frees the multiple needles from the frangible attachment to the member and ejects the member from the cover leaving the needle bearings captured by the race in the cover.

摘要： A first substrate may be joined to a second substrate using an adhesive body. The adhesive body is formed from an adhesive composition containing at least one epoxy resin, at least one heat-activatable curing agent, and at least one radiation-curable compound. A first surface of the adhesive body is exposed to an amount of radiation effective to cure at least a portion of the at least one radiation-curable compound present in proximity to such first surface, thereby rendering said first surface less tacky and/or more resistant to deformation. A second surface of the adhesive body is then applied to a surface of said first substrate. A surface of the second substrate is thereafter positioned proximate to or in contact with the first surface of the adhesive body and the adhesive body heated to a temperature effective to activate the heat-activated curing agent and induce curing of the at least one epoxy resin.

摘要： The present invention is directed to a high expansion two-component structural foam that expands to about twice its original volume while maintaining good cell structure. The foam of the present invention is based on epoxy resins. Each component of the foam system exhibits storage stability, e.g., no phase separation, yet reacts when combined to provide a cured material having exceptionally good compression strength and modulus. The blowing system used to prepare the foam produces a foam which is uniform in appearance and is essentially free of the large voids often found in conventional two-part thermosettable compositions, even when a relatively large mass is utilized.

摘要： An improved protective storage cap for a rod-shaped device or instrument, particularly a fountain pen, wherein the female threads for securing the device within the cap are disposed within an axially and rotationally moveable ring. The ring is held stationary in the cap by the axial thrust of a compression spring while the male threads of the device are being rotationally engaged with or disengaged from the female threads of the cap. The cap cannot be overtightened and thereby damaged because further rotation of the device after full engagement of the threads serves only to overcome the restraining thrust of the spring and the moveable ring simply rotates in its cap with the device. The axial freedom of the ring and spring also permit the device to enter the cap to a depth sufficient to form a snap seal between the working end of the device and a chamber recessed within the cap, whereby the tool of the device, for example the writing nib of a fountain pen, sealingly is isolated from the outside environment. The pen body can be secured in the cap either by the snap seal alone or by the combination of the seal and the engaged threads. The cap can be stored on the non-working end of the device while the device is being used. Since the threaded ring is able to slide axially, its threads cannot be forced onto the non-working end, and thereby marring of the surface of the pen is prevented.
摘要翻译： 用于棒状装置或器具，特别是钢笔的改进的保护性储存帽，其中用于将装置固定在盖内的阴螺纹设置在轴向和旋转可移动的环内。 环通过压缩弹簧的轴向推力固定在盖中，同时装置的外螺纹与帽的内螺纹旋转地接合或脱离。 盖子不能过度拧紧并因此被损坏，因为在完全接合螺纹之后，装置的进一步旋转仅用于克服弹簧的限制推力，并且可移动环仅在其装置的盖中旋转。 环和弹簧的轴向自由度还允许装置进入盖子的深度足以在装置的工作端和凹陷在盖内的腔室之间形成卡扣密封，由此装置的工具，例如 钢笔笔尖密封地与外界隔绝。 笔体可以通过单独的卡扣密封件或通过密封件和接合螺纹的组合固定在盖中。 在使用设备时，盖可以存储在设备的非工作端。 由于螺纹环能够轴向滑动，所以其螺纹不能被迫进入非工作端，从而防止了钢笔表面的磨损。

摘要： A document feed tractor in which pins which drive the paper upon entry into perforations in margins of the paper along the edges thereof are connected to a belt on beams cantilever mounted thereto. A guide and support bar holds the beams and the pins down so that they travel along a linear path entering and leaving the perforations at opposite ends of the path. In order to drive the paper precisely, especially at high speeds where the belt and pins start and stop, without denting or ticking the paper and to maintain alignment of multi-part documents (without shingling), an adjustable shelf is located on the inside of the tractor so that the paper overlies the shelf. The elevation of the shelf with respect to the pins is selectively set in accordance with the thickness of the paper. The tractor can then be set so that the web is maintained at the center line or pitch line of the belt, thereby insuring precision feeding of the form even at high speeds with rapid accelerations and decelerations.

摘要： A tractor for feeding perforated paper forms as in a printer, to and around a platen where a print head impresses characters or other symbols on the paper. The tractor has an endless belt with pins engageable in the paper before, during and after engagement with a drive sprocket which drives the belt in such a manner that the load on the paper is polarized to one side of the drive sprocket, preferably the side between the drive sprocket and the platen. The tractor has guide members (idler sprockets or shoes) on opposite sides of the drive sprocket which define a generally triangular path for the belt with the belt engaging the sprocket only on one reach of the belt so that the load on the belt is relieved where the paper enters the tractor; the belt there being in an unstressed, relatively slack condition so that the pitch (spacing) between the pins can vary as by flexure of the belt or tilting of the pins, allowing the pins to enter the perforations in the paper without damaging the perforations or walking out of the perforations after entry.

摘要： An improved lid mechanism for a web feed devices such as tractors for feeding perforated paper webs in printers, copiers and the like, wherein pins on which the lid is pivotally mounted for movement between open and closed position are unloaded (do not have any force or bias applied thereto) when the lid is in its open and closed position. The lid, when closed, covers the paper and is then spaced by a gap from the surface of a frame along which the paper is fed by a pin drive such as a belt having pins which extend into perforations of the paper. A depending leg of the lid has a block with surfaces disposed at an angled to each other. These surfaces extend from a corner of the block. One of these surfaces is preferably perpendicular to the surface of the lid which defines the gap. The other of these surfaces defines the position of the lid in its open position. These surfaces bear against the outer wall of the side plate of the frame of the device (the tractor) and are biased thereagainst by a flat spring mounted on the side plate. This spring bears against surfaces of the block opposite to the surfaces which bear against the outer side wall. The location of the lower surface of the lid and the size of the gap is defined by a pin and slot hinge arrangement. The slot is longer than the stroke of the pin which is executed as the lid moves between its open and closed position. Accordingly in both the open and closed position the block is under compression and the pin is unloaded. The lid may be molded and is an integral body of plastic.
