IPC: H02J9/08
Filed: 1984-10-18
Abstract: On start-up, the actual output voltage of the generator 6 is boosted higher than the normal output voltage prior to connection of a load. A prime mover 15 is started in response to interruption of the commercial supply 3 and after load circuit breaker 8, 9, 10 have been opened. When the generator 6 output voltage has reached 80% of the normal output a circuit breaker 14 is closed, then a switch 30 opened and a switch 31 closed so that on automatic voltage regulator 25 receives a higher reference voltage, and then a normal output voltage detecting contact 35 is opened and a boosted output voltage detecting contact 34 closed. When the actual output voltage is 110% of the normal voltage, the load contactors 8, 9, 10 are closed in sequence whereafter contact 31 opens and 30 closes and then contact 34 opens and 35 closes so that circuit 25 regulates the output at the normal level.

Patent GB-2184749-A (GB)
Title: Leak protection apparatus
Inventor: GILL GEORGE BARBER
IPC: D06F33/47
Filed: 1985-12-30
Abstract: Leak protection apparatus for use with a domestic appliance comprises a tray 2. Supply hoses for the machine 1 pass through the tray 2 as does a waste pipes. Moisture detectors 7 and a vibration detector 8 are also included in the tray 2. In use the machine 1 operates as normal and provided that there is no leakage of water into the tray 2 the protection apparatus remains unactivated. If a leakage should occur then the water will gather in the bottom of the tray 2 and be detected in the first instance by the moisture detectors 7 which activates a warning light 10 and buzzer 11. If the leakage continues the sensors 7 cause the disconnection of the water and electricity supplies. Excess water which gathers in the tray 2 exhausts through the outlet pipe 5. <IMAGE>

Title: Plug valve
Inventor: JONES TERENCE VALENTINE
IPC: F16K31/72
Filed: 1986-02-03
Abstract: A fast acting plug valve comprises a hollow plug 10 slidable on a carrier 13 and sealing a neck at 29 between a pressure vessel, volume 1, and an outlet manifold 12. The plug 10 is urged into sealing engagement with the neck by increasing the gas pressure within the plug, volume 2, until it is at least equal to the pressure in volume 1. To open the plug valve, a pilot valve 18, 19, controlled by a magnetic spool valve 25 and pressure lines, is opened to allow gas in volume 2 to escape through an aperture 17 to a volume 3 at a lower pressure, so that pressure in volume 2 becomes less than pressure in volume 1. The pilot valve comprises a movable sealing ring 18 bearing on a sealing disc 19 carried by a shaft 20 connected to the plug, 10. The shaft 20 carries a damping stop 22 that during the opening of plug 10 enters the aperture 17 (Fig. 4) to reduce gas flow from volume 2 to volume 3. <IMAGE>

Title: Yarn selection in Axminster carpet looms
Inventor: COATES HERBERT
IPC: D03D39/08
Filed: 1986-04-26
Abstract: An Axminster carpet loom has yarn selection means comprising a series of elongate yarn carriers (18) each with series of spaced apertures (34) for different tufting yarns (36) and being longitudinally reciprocatable to present a selected yarn to an associated gripper (12). Each carrier has a series of transverse selector pegs (38) at the same spacing as the yarn apertures and a solenoid-operated plunger (86) in a fixed position extends a chosen one of the pegs as it comes into register with the plunger. The selected peg is extended after passing a fixed abutment plate (76) and, when the carrier returns towards the start position it will be arrested by the extended peg striking the plate so that the corresponding yarn is presented to the gripper. When the selected yarn lengths have been severed, the pegs are retracted and the carriers return to this initial position. The solenoids (90) operate the plungers under the control of a micro-processor. <IMAGE>

Title: Height-weight monitoring system
Inventor: WHITING JOHN
IPC: G01B5/06
Filed: 1988-03-04
Abstract: Within a base K there is accomodated a weighing platform F to which is pivotaly connected to a superstructure which can be locked into the vertical or horizontal use positions. In both positions everything within, or on, the superstructure transmits its weight to the platform F and is recorded as weight, but by tareing out the units's weight the weight of a patient can be directly recorded. When a patient is standing on platform F a cursor G can be activated to descend to contact the patient's head and record the height. In the case of young children and infants the system is used horizontally when the weight is registered as before but in the case of height the new datum line for the feet is a lift-up flap J which operates in conjunction with the same cursor G. All these measurements are automatically taken and data logged with further details via keyboard A. <IMAGE>
