    摘要： Expandable thermosettable compositions containing at least one epoxy resin, at least one finely divided thermoplastic polymer powder, at least one blowing agent, at least one curing agent, and at least one filler are suitable for the production of thermosetting laminated bodies with a tacky surface. These laminated bodies can be produced and handled in a simple manner and are suitable for stiffening and reinforcing flat structural components, in particular vehicle body structural components, such as vehicle body frames, doors, trunk lids, engine hoods and/or roof components in automobile construction. The expandable thermosettable compositions are also suitable for the production of thermosetting, thermally expandable shaped articles for reinforcing hollow structural members by the injection molding process. In preferred embodiments, the composition is injected onto a metallic or thermoplastic carrier. These thermally expandable shaped articles are especially useful in the production of automobiles and other vehicles to maintain or increase the strength of structural members such as rockers, pillars, radiator support beams, doors, reinforcing beams, and the like.

    摘要： Expandable, thermally curable compositions containing at least one epoxy resin, at least one polyester, at least one blowing agent, and at least one curing agent are useful as adhesives and structural reinforcement materials. When foamed and adhered to a metal substrate surface, such polyester-modified foamable compositions can exhibit improved adhesion to the substrate surface after exposure to a corrosive environment, as compared to compositions that do not contain polyester. Furthermore, these compositions can exhibit improved flow properties in the uncured state at temperatures between 50 and 100° C. They are granulatable, with the granules produced thereby having non-tacky surfaces at room temperature and being capable of being readily processed into molded objects by injection molding processes.

    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： 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： 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 tractor feed mechanism combines, in a unitary assembly, components which provide the capabilities of separate, independent, left and right-hand tractors and their support and drive shafts. The assembly has fewer parts than a tractor feed using separate tractors thereby reducing the cost and increasing the reliability of the feed mechanism. In the unitary tractor feed, endless tractor belts are positioned by lid belt guide members which are slidable on a bar having a surface which provides a platform which sets the height of the belts, while the web is disposed on a gap between an upwardly facing surface of the guide members and a downwardly facing surface of the lid. The bar and a sprocket which engages the belt extends laterally (width-wise) of the web a distance at least as wide as the longest web to be fed. The guide members contain flexural fingers providing detents which are cammed into locking engagement against the bar when the lid is closed; allowing, when the lid is opened, the detent to spring away from the bar so that the guide members can be moved to align the belts guided therein with the perforations in the web.
