Abstract: In a pneumatic pressure regulator comprising a ported housing having an internal bore, within the bore a spring-pressed piston mounted for reciprocation between advanced and retracted positions, and valve means associated with the piston and operative to direct the flow of air to the respective housing ports; the improvement comprising a housing the bore of which is inwardly tapered in the direction of spring-pressed piston retraction. This results in decreased friction, and improved hysteresis characteristics.

Abstract: A hand-drop motor assembly for use in an encoding apparatus is positioned in the vicinity of a hand-drop region of the encoder check guide path. It includes a motor which has a motor shaft extending out the top end thereof. Mounted to the shaft is a roller. Rotatably mounted to the motor shaft is a bracket, upon which is mounted a wheel, which is in compressive contact with the roller. When the motor is turned on, the bracket rotates such that the wheel moves into the hand-drop region, contacting a document therein and then moves the document along the check guide path to an encoder station.

Abstract: The encoder cartridge includes a cartridge body which is divided interiorly into upper and lower portions. A ribbon is mounted on a feed spool in the upper portion and feeds through a series of guide elements to a lower portion which includes a take-up reel upon which the ribbon is wound by a traction gear member which is in turn advanced by a motor. The cartridge body is configured to match closely that of the feed spool and take-up reel, with an opening at one end of the body for the ribbon, the opening being substantially smaller than the width of the cartridge and similar to the diameter of the encoder font wheel.

Abstract: A remote-driven encoder which includes a feed tray assembly (12) and an autofeed roller assembly (14) which moves checks one at a time into a check guide path. A deskewing roller (46) moves the checks from the tray assembly (12) to the autofeed roller assembly (14). The check is moved along the check guide path by first and second drive assemblies (16, 20). Intermediate of the two drive assemblies (16, 20) is an encoder assembly (18) and a ribbon cartridge (22). The apparatus includes a plurality of sensors which provide information for control of the movement of the check, including a preload sensor (70), a detect sensor (88), and a leading edge sensor (90), among others. The check moves through a substantial angle from the feed tray past the encoder assembly. The encoded check is moved around an eject roller and then into a catch tray at the rear of the apparatus.

Abstract: A pneumatic windshield wiper includes a compressed air motor provided with a piston which mounts a pair of actuator vanes one of which functions with a fixed electric sensor on the motor housing to establish the "park" position of the wiper blade. The other sensor actuator vane is adjustable along the length of the piston rod and functions with the sensor to establish the extended, adjustable position of the wiper blade. The sensor is included in an electronic circuit which controls operation of an electric solenoid valve and hence delivery of compressed air to the wiper motor.
