摘要： Apparatus for supporting and guiding a machine for operating on sheet material such as cloth while the material lies on a surface of a supporting structure having a pair of substantially parallel sides extending lengthwise of the structure, the apparatus comprising a carriage adapted for movement lengthwise of the supporting structure along a path substantially parallel to the sides, a guide arm on the carriage extending across the supporting surface between the sides and spaced from the surface, and a support arm connected to the guide arm extending at an angle thereto and located in spaced relation to the supporting surface, the support arm carrying at one end a machine for operating on the sheet material, and the support arm being pivotally movable about an axis substantially parallel to the longitudinal axis of the guide arm and along a plane disposed substantially perpendicular to the supporting surface. The support arm also is movable longitudinally along the guide arm and also is pivotally movable about an axis substantially perpendicular to the longitudinal axis of the guide arm. The support arm extends crosswise of the support arm and carries a balancing weight on the other end, and the balancing weight can be provided by another machine carried on that end of the arm. The machine can be provided with an improved supporting base characterized by a sheet of resilient material such as spring metal having an intermediate portion shaped to be spaced from the supporting surface, a leading edge portion contacting the surface and a trailing edge portion shaped to facilitate movement of the resilient sheet over and along the work surface.

摘要： A safety gate that has a continuously adjustable width for insertion across a lateral opening such as a doorway. The gate has a generally U-shaped gate frame including two tubular frame members that are slidably connected in a telescoping relationship. A latch is operable to displace the telescoping portions by a pre-selected displacement relative to each other, so that part of the tubes are deflected and the gate frame applies an outward lateral force to the doorway opening sides to retain the gate across the opening. The gate includes a walk-through door with a door latch for latching the door closed and an indicator for indicating when it is not fully closed and latched. A force-distribution bar on at least one side of the gate distributes the force from that side of the gate so that it is applied at two points on that side of the doorway opening.

摘要： Method and apparatus for storing digital information in a dense memory structure. A semiconductor substrate has a thin insulating layer formed thereon. Over the thin insulating layer is formed a dielectric charge-storage layer. A piezoelectric bimorph cantilever arm has a tip formed at its free end to access certain memory sites defined by charge-storage regions in the charge-storage layer. To write infromation in the form of charges into a memory site the tip contacts or is in close proximity to the surface of the charge-storage layer and an electric field is applied between the tip and the substrate to induce charges to tunnel through the thin insulating layer into the charge-storage layer where the charges are stored as trapped charges. Information is read from a storage-site by spacing the tip of the cantilever arm a distance from the surface of the charge storage layer and applying an electric field between the tip and the substrate. The capacitive force on the tip is then measured to determine the amount of charge stored in that memory site. Alternatively charge is deposited directly on the surface of a single insulating layer. Charge sites are arranged in circular tracks on a rotating substratge to provide a high density memory array. Charge sites are also arranged in linear tracks by forming alternating layers of conductive and non-conductive substrate layers over which are formed thin insulating layers and charge-storage layers. This produces a number of spaced-apart charge-storage tracks. Tracks are also provided by depositing metal strips or scribing grooves on the surface of a device.

摘要： A side by side bicycle has a frame including rear forks, a transverse crank tube, an upright seat tube and an upright steering tube. A rear wheel is mounted in the rear forks, and a crankshaft is journalled in the crank tube. There is a first pair of cranked pedals on one end of the crankshaft on one side of the frame and a second pair of cranked pedals on the other end of the crankshaft on the other side of the frame. A chain and sprocket mechanism connects the crankshaft to the rear wheel. A steering spindle is journalled in the steering tube, and front forks are secured to the steering spindle and carry a front wheel. From the steering tube a duplex yoke has yoke bars that extend laterally at a variable orientation. At one end of one yoke bar there is a handle bar tube from which a handle bar post projects upwardly to carry a first set of handle bars. The other yoke bar at its opposite end carries a steering head with a steering sleeve rotatably mounted in it. A steering post extends upwardly and is axially and rotatably movable in the steering sleeve, being clamped in a selected position. A second set of handle bars is on the steering post, at the bottom of which there is a chain interconnecting the steering sleeve and the steering spindle, the chain runs passing on opposite sides of the adjacent yoke bar.

摘要： A cutting machine comprising a housing having a base, a motor carried by the housing, a knife blade having a cutting edge and carried by the housing for reciprocal motion generally normal to the base in response to operation of the motor, a presser foot movably carried by the housing located in spaced relation to the blade cutting edge and movable toward and away from the base, and characterized by an elongated guard connected to the presser foot and located closely adjacent the blade edge and guided supported in the housing for movement along the blade edge in response to movement of the presser foot toward and away from the base. There is included an arrangement for releasing the presser foot when the motor is turned off allowing the pressure foot to rest on or near the base and maintain the guard in place along the blade edge when the motor is off. The machine includes a sharpening mechanism movably carried by the housing for travel in opposite directions along the blade when it is to be sharpened, and the guard is flexeible to accommodate the presence of the sharpenng mechanism. In response to movement of the presser foot, the flexible guard moves along a first path closely adjacent the blade edge, a second path offset from the first path and defined in the machine housing and a third path joining the first and second paths and extending about along the sharpening mechanism. During movement of the sharpening mechanism along the blade, the flexible guard is guided away from the blade by a guide carried by the sharpener mechanism and is returned close to the blade edge as the sharpener returns to its rest position.

摘要： A set of program elements (e.g., transcoders) are grouped together as an administrative unit. Instead of caching the individual outputs of each program element, preferably only the aggregate output of the set of program elements, taken as a whole, is cached. The inventive technique enables the effective re-use of intermediate content. In an illustrative client-server based implementation involving a transcoding service located at a server, the cached information may be shared across multiple server instances to obviate redundant processing. With the present invention, a caching mechanism in a complex software system may be extended in a user-configurable manner by setting up optimal intermediate caching points that are defined by groups of programs used in long computations.

摘要： The present invention relates to a latch for coupling tether straps attached to child vehicle seats to anchorages provided on the vehicle, e.g., anchorages provided on the package shelf of the vehicle or anchorages located at the crease of the seat bottom and seat back. The latch provides advantages over the common “T” hook currently in use, including a push button remote from the hook of the latch. In addition, the latch may include an opening for attachment of the tether strap. In one preferred embodiment, the latch further includes a plate which is coupled to a strap length adjuster, the plate and adjuster being pivotally connected to permit side-to-side rotation of the adjuster relative to the latch to prevent bunching or twisting of the strap which can cause the belt to loose its ability to uniformly distribute a load across its width. Furthermore, the adjuster itself may be coupled to a plate which is pivotably coupled to the plate attached to the latch, to thereby permit movement of the strap about two perpendicular axes.
