Abstract: A medication dispensing and monitoring system includes an acknowledge-back pager, a carriage communicating with the pager, and a medication unit dispensing stored medication. The pager receives prescriptions and transmits messages back to a physician or health care organization. Prescriptions received by the pager are stored and processed by a pager processor. The pager processor communicates with a carriage controller via a series of electrical contacts. At a prescribed time, a motor in the carriage causes the medication unit to dispense the prescribed medication. Numerous medication units may be assembled to accommodate different forms of medication.

Abstract: Three tandem drive units are provided. Outward variable volume working chambers at one end of the drive units are connected via passageways in the piston rods with inward variable volume working chambers at the opposite end of the drive units.

Abstract: A two door assembly (10) for an elevator car (11) includes a high speed door (12) and a low speed door (14) that move between an open and closed position to close the entrance (16) of the elevator car. The doors (12, 14) are retained slidably between a header (18) disposed along the top of the car entrance and a door guide (20) disposed along the bottom of the car entrance (16). A drive mechanism (22) moves the high speed and low speed doors (12, 14) between the open and closed positions. A drive arm (24) interconnects the doors to move the low speed door (14) at approximately one-half the speed of the high speed door (12) driven by the drive mechanism (22). One end (38) of the drive arm (24) is connected pivotally to the door guide (20) of the elevator car (11). Each door (12, 14) has a pin (32, 34) extending from a bracket (26, 28) connected to each respective door for sliding engagement with a pair of slots (42, 44) that extend longitudinally along the drive arm (24).

Abstract: A conveyor device for accelerating a series of products comprises a feed device for supplying products at a feed velocity, an acceleration device which is positioned downstream thereof, and a transfer device for taking up the accelerated products and delivering the products at regular intervals and at an accelerated velocity. The acceleration device comprises a transport path, with a belt of projections on either side thereof, which belt rotates at a lower velocity than the transport path. The transport path carries along the products at an accelerated velocity until they bear against the projections. After they have come to bear against the projections, the accelerated products are taken up by the transfer device. Due to the fact that the position of the projections is known at all times, an accurately determined position of the accelerated products is obtained in this way and shifts of the products which have occurred during acceleration are compensated for.

The fluid motors each include a piston and a piston rod which is slidably supported within a passage in an end cap at one end of the motor cylinder. Each end cap and piston rod together form an integral part of the exhaust system which allows the fluid motors to be sequentially exhausted.

Abstract: A high speed shuttle conveyor includes two motor-driven belts for moving two carriages forwardly to rapidly propel an article conveyor from a starting position to an ending position. The belt movements are reversed to return the carriages to the starting position. Each carriage has a retractable pusher element for imparting forward movement to the article conveyor, and a retractable retention element for preventing the article conveyor from moving forwardly at a faster speed than the pusher element. When each carriage reaches the limit of its forward stroke the retention elements exert snubber actions on the carrier; the carrier is safely decelerated to a motionless condition and released.
