Title: Mounting and adjusting a vehicle brake light switch
IPC: H01H9/02
Filed: 1981-04-27
Abstract: A vehicle brake light switch (3) of the type having a cylindrical body with a threaded portion (32) and a push actuator (31) is mounted in an aperture (21) in a support plate (2) by means of a holding ring (1) having longitudinally extending resilient tabs (111) provided with inwardly directed thread segments (113) which are engageable with the threaded portion (32) of the switch body. The holding ring (1) is inserted into the aperture (21) until a collar (12), at one end thereof bears against one side of the support plate (2) and tongues (114) abut against the other side, thereby preventing longitudinal displacement. A lug (121) received in a notch (22), in the aperture (21), prevents rotational displacement. Then the switch body (32) is pushed into the holding ring (1) and the brake pedal (5) is depressed thereby operating the push actuator (31) and longitudinally displacing the switch body (32) to the approximate desired position. The switch body (32) which is in threaded engagement with the thread segments (113) may then be finely adjusted manually by angular displacement. <IMAGE>

Title: Mixing and dispensing system
Inventor: SPENCER DENNIS LINCOLN
IPC: A01K7/02
Filed: 1982-11-19
Abstract: A system for providing a supply of two fluids mixed in predetermined proportions comprises a first container (12) and a second container (30) having a common outlet. The second container communicates with the common outlet by way of a one-way valve which prevents fluid from the first container leaking into the second container. A floatable vessel (24) within the first container communicates with the second container for providing an inlet for supplying fluid to the second container from a supply tank (10). The level of fluid in the second container can thereby be controlled precisely in dependence upon the level of fluid in the first container, so that the fluids are supplied to the common outlet in precisely determined proportions. <IMAGE>

Title: Control system for an electronically commutated DC motor
Inventor: ERDMAN DAVID MARVIN
IPC: H02P6/18
Filed: 1983-04-20
Abstract: The application of a DC voltage to the winding stages of the stationary assembly of the motor is controlled to provide an effective voltage thereto by commutating the winding stages to apply the DC voltage thereto in sequence to cause rotation of the rotatable assembly of the motor. A neutral conductor voltage of the motor is approximated, in the case where the motor has no neutral conductor, and compared with the back emf of one of the windings stages to obtain an output representing the angular position of the rotatable assembly. The winding stages are commutated in response to this output when a predetermined angular position is reached. The DC voltage applied to the winding stages is pulse width modulated by alternately pulse width modulating first 41 and second 47 drive circuits. The first drive circuit associated with a winding stage which remains on after commutation is pulse width modulated until a predetermined time after commutation and then there is a shift to pulse width modulate the second drive circuit associated with the winding stage which will remain on after the next commutation. The motor may be used in a laundering apparatus. <IMAGE>

Patent GB-2130402-A (GB)
Title: Electro-pneumatic system
Inventor: HILLIER ALAN JOSEPH
IPC: A61M16/10
Filed: 1983-11-04
Abstract: A system (e.g. for life support system) (10) supplying pressurised gas has an electrical compressor (12) as a primary source of gas and a gas bottle (14) as a secondary source. The primary and secondary air lines from these sources are connected through a shuttle valve (22) to an outlet line (16). Solenoid valves (20, 26) in the primary and secondary gas lines are connected in the electrical circuit which also powers the compressor (12) and are controlled by a pressure-sensitive switch (30) monitoring the gas pressure in the primary gas line. Normally, the primary gas line valve (20) is open while the secondary gas line valve (26) is closed when the valves are energised through the switch, during operation. If, however, the power supply fails or there is a loss of pressure in the primary line the valves are de-energised to close the primary line and open the secondary line, allowing pressurised gas from the gas bottle (14) to be supplied to the outlet line (16). Additional controls can be provided for monitoring minimum and maximum gas pressure levels in the secondary and outlet lines. <IMAGE>
