Title: Hydraulic master cylinders
IPC: B60T11/28
Filed: 1980-08-18
Abstract: A hydraulic master cylinder (1) comprises a body (2) formed from tubular stock. A closure plug (4) is secured to the body (2) and includes an outlet port (9) in communication with a working chamber (8), and a reservoir port (9A) connected to a fluid reservoir. In the rest position of the piston (6) the working chamber (8) communicates with the reservoir via radial passages (19) and axial passage (16) of a tubular member (15) which is integral with the closure plug. At the commencement of a pressure generating stroke the passages (19) are closed by main seal (7). The design obviates the need for ports which pierce the body (2) and by providing a blind bore (17) in which the tubular member (15) is received obviates the need for the usual secondary atmospheric seal between the piston and the body. <IMAGE>

Title: Video player/recorder cleaning apparatus & method
IPC: G11B23/087
Filed: 1980-12-16
Abstract: A cleaning device for a video tape player/recorder is in the form of a cassette case adapted to be placed in the cassette recess of the player/recorder. A cleaning ribbon 88 in the case is extracted by one of the guide pins 56 of the auto- threader of the player/recorder, this motion causing ribbon 88 to wipe across audio head 31 and to become engaged with rotating video head 34. During the cleaning operation, the take up drive spindle 62 drives an endless shut-off ribbon 176, 178 until a slot (180, Fig. 8) therein becomes aligned with the path from a lamp 66, via a slot (182) in the cleaning ribbon, to a detector 74, whereupon the auto- threader pins 56 (et al) retract, drive to take-up spindle 62 is stopped and the supply spindle 64 is driven to pull on a retracting ribbon 94 so that the cleaning ribbon is pulled back into the cassette case. The cassette case also carries a pad 90 (Fig. 9) to clean the rotating capstan 38 and pinch roller 40 during head cleaning. The cleaning ribbon 88 and pad 90 are absorbent to receive a cleaning liquid and are housed together in a cartridge 84 (Fig. 9) which can be removed from the cassette case. <IMAGE>

Title: Control system for AC induction motors
IPC: H02P6/00
Filed: 1981-02-24
Abstract: A control system for reconnecting the primary windings of AC induction motor (14) into a wye-connection for coupling to a source of three-phase electric power at light loads to effect energy savings includes switching means (68), power sensing means (46), and differential comparator means (66). The comparator means is responsive to a control signal (64) and an adjustable reference signal (72) for generating an actuating signal (70) for operation of the switching means (68). Upon the occurrence of the control signal, which is directly proportional to the power applied to the induction motor, decreasing below a predetermined level, the differential comparator means deactivates the switching means to cause reconnection of the induction motor to the electric power source by a wye- connection.
Patent GB-2071222-A (GB)
Title: Medical infusion system and method of operation
IPC: A61M5/142
Filed: 1981-02-25
Abstract: A medical infusion system has a pump and cassette combination for conducting fluid or semi-solids from an upstream flexible conduit portion (11) to a downstream flexible conduit portion (13) of the system. The cassette (18) includes a rigid enclosure defining a pumping cavity (25) and has a window with a diaphragm (26) spanning the window. The diaphragm is engaged by an actuator (28) on the pump for varying the volume of the pumping cavity. Restrictors (21, 22) at the upstream and downstream portions close off and open, respectively, the flow into and out of the pumping cavity in a sequence related to the actuator movement such that the pumping cavity alternatively is filled and substantially emptied. To minimize the detrimental effects of air in the pumping cavity: 1) the actuator is operated to substantially increase the volume of the pumping cavity prior to opening of the upstream portion; and 2) the actuator is operated to reduce the volume of the pumping cavity to a residual volume of less than about 0.07 ml subsequent to closing of the upstream portion and opening of the downstream portion. <IMAGE>

Title: Integrated injection logic cell having self-aligned collector and base with reduced base resistance and method of making same
IPC: H01L21/321
Filed: 1981-07-16
Abstract: Base resistance in an integrated injection logic cell is reduced by providing a low resistance conductive path 80 over the device cell and contacting the base regions 88, 90, 92, of vertical transistors in the cell. In fabricating the I<2>L cell a first intrinsic polysilicon layer 63, 64, 65, is formed over the surface of the device cell, and N-type dopant is diffused through the polysilicon layer to form the N + collectors 66, 68, 70, of the NPN vertical transistors. Silicon oxide is formed over the doped polysilicon and the undoped intrinsic polysilicon is then removed. Exposed edge portions of the N doped polysilicon is then oxidized to completely insulate the surface of the polysilicon. A second layer 80 of intrinsic polysilicon is then formed over the device cell and P type dopant is diffused through the second polysilicon layer to form the emitter 84 and collector 86, of a lateral PNP transistor and to contact the base regions 88, 90, 92, of the NPN vertical transistors between the N + collectors. The self-aligned collectors and bases of the NPN transistors and the reduced base resistance increases the speed of the I<2>L device. <IMAGE>
