Abstract: An actuating mechanism for sliding doors provided on the passenger side of conventional panel type trucks, commonly called vans, is intended to be either installed in the vehicle at the time of its original manufacture, or installed at any later time, without substantial modification of the vehicle. A winch assembly (44) including two separate winding drums (74, 86) on a common shaft (87) and driven by the shaft through springs (162, 174) and a positive driver (170), is mounted over the rear wheel well of such a vehicle. A guide assembly (50) including a pulley (54) and a pivoting guide member (62) is installed in an aperture cut in the door frame. A single pulley (56) is installed at the lower rear corner of the door opening, and a guide tube (58) is installed in the door. A flexible cable (52) is connected to an arm added to the latch operating mechanism, and extends through the guide tube (58), around the pulley (56), through the guiding assembly (50) to the winch assembly (44), for opening the door. A second cable (60) is attached to the rear edge of the door, passed around the pivoting guide (62) of the guide assembly, and fastened to the winch assembly (44) for closing the door. As the door closes, the pivoting guide (62) guides the flexible cable (60) to a position perpendicular to the rear edge of the door to pull the rear edge of the door into latched position. A switch (55) operated by the pivoting guide (62) connects an additional winding on an electric motor (138) to provide a high force for latching the door, allowing low force to be used for sliding the door to reduce the chance of personal injuries while closing the door.

Abstract: Electrophotographic apparatus for producing high quality, toned, first-generation images on a suitable flexible record or image receiving medium such as paper. Because of its unique characteristics, however, electrophotography cannot be readily adapted to provide a dry output from a typesetter. The first problem is the quality of the output. Normal copier quality is far below the standards used in the graphic arts industry. A second problem concerns the dark decay rate of a photoconductor. In typesetter applications where exposure of the photoconductor is carried out letter by letter or computed raster line by raster line, the time between charging and toning may be as long as ten to twenty minutes as compared to, say, ten seconds or less for a typical office copier. Therefore, if electrophotography is to be used to produce dry developed output from a typesetter, the photoconductor must exhibit an extremely low dark decay rate. Therefore, a principal object of the present invention is to provide electrophotographic apparatus for producing high quality, toned, first generation images. A further object of the present invention is to provide electrophotographic apparatus for use with a typesetter which meets the various requirements set forth above. These objects, are achieved, according to the present invention, by providing a particular configuration of elements, for charging, exposing and developing images on a flexible substrate, such as paper, coated with a layer of photoconductive material, such as zinc oxide. In particular, the apparatus includes: (a) a transporting device, such as a drum (74), for supporting and transporting an image receiving medium (14 or 60), such as ZnO-coated paper; (b) a charging device (22 or 80), such as scorotron, disposed adjacent to the transporting device (74), for applying a uniform charge on the photoconductive surface of the image receiving medium; (c) an exposing device (24 or 82) such as an illuminated character mask (30) or laser scanner (94, 98, 100, 104), for directing radiation onto the photoconductive surface after charging at the areas where toned images are to appear, thereby to discharge the surface at these areas; and (d) a developing device (42 or 86) disposed adjacent to the transporting device, for applying liquid toner to the discharge areas on the photoconductive surface after exposing.

Abstract: A dispenser reel and container are integrated into a unitary foldable structure (10) which when folded into an assembled configuration, is suitable for the shipping and dispensing of a spool of wire, cable, and the like, that may be wound on a spindle or other hollow cylindrical core device. In one embodiment, the invention is fabricated out of flat corrugated paperboard that is easily cut to appropriate dimensions and provided with fold creases (e.g. 102, 104, 106, 108) or score lines that make it readily foldable around the packaged spool of cable or the like. In said one embodiment, the cut corrugated paperboard comprises two interconnected substantially rectangular portions (12, 14) and two interconnected substantially circular portions (16, 18), each circular portion having partially cut fold-out wing portions (48, 50, 52, 54). The substantially rectangular portions, which form two of the walls of the container, have margin portions (e.g. 22, 24, 30, 32) along their perimeters which form the remaining four walls of the container when they are folded into place. A first circular portion (18) is integral to a selected margin portion (30), while the second circular portion (16) is connected to the first by a bridge (20) which also functions as a stand for the assembled dispensing reel. The fold-out wing portions are folded into the center of the reel to form a spindle upon which a spool of dispensable product such as cable is to be mounted. In one embodiment, the fold-out wing portions have interlockable tabs (e.g. 60, 64, 68, 72) that provide means for locking the wing portions together into a secure spindle configuration.

Abstract: A hydraulic system for trimming a marine outboard drive (49), and wherein a single actuator (11) for moving the propulsion unit (49) is used for both trim and tilt. The actuator (11) is connected to a hydraulic pump (3). An amplifier (5) for amplifying the pump pressure is connected to the actuator (11). The amplifier (5) has first and second ports (7, 9) connected to the actuator (11) and to the hydraulic pump (3). The amplifier (5) includes a switch (29) for bypassing the amplifier (5) to pass the hydraulic fluid from the pump (3) to the actuator (11) without amplification. The switch (29) is operable for by passing the amplifier (5) for rapidly tilting the propulsion unit (49) and operable for connecting the amplifier (5) within the hydraulic circuit to develop increased pressure for trimming the propulsion unit (49). The hydraulic amplifier (5) includes a piston (13) movable within a cylinder (21). Movement of the hydraulic amplifier piston (13) to one end of the hydraulic amplifier cylinder (21) actuates the switch (29) to bypass the amplifier (5) and movement in the other direction away from that end, switches the amplifier (5) to its amplification mode, the amplifier (5) continuing in its amplification mode until the amplifier piston (13) reaches a limit switch member (35) placed in its path to bypass the amplifier hydraulic circuit.

Abstract: A termination block for ribbon cable (1), wherein the ends of the conductor wires in the ribbon cable form pin (12) of a connector for attaching the ribbon cable to a printed circuit board or the like. Insulation is removed from the end of the ribbon cable, and the individual conductors are placed in grooves (7a, 7b) in a base member, and retained by a cover member. A forming blade (30) is passed through apertures, aligned with the grooves, in both base and cover members to force a portion of conductor wire through the base member. In a preferred embodiment, the conductor wire is formed into a U-shape protruding from the base, which is then compressed to form a pin (12) to mate with holes in a printed circuit board or the like.

Abstract: A technical problem with a four pole wave wound direct current motors is that excessive currents flow in single turn windings when such a motor is operated at relatively low speeds and/or relatively high voltages, and that plural turn windings can not be formed for a reduced number of commutator segments or from heavy gauge rectangular wire, to efficiently fill armature slots. This problem is solved by a plural turn winding (19) having two ends (95, 97) for connection to commutator segments substantially 180o apart on the armature (10) and with at least four sides (82, 84, 86, 88) defining at least two open turns, for engaging slots (17) in the armature core (16) which are spaced substantially 90o apart. A three open turn winding (100) is also disclosed. The number of open turns is limited only by space available in the armature coil slots (17).
