Patent GB-2170654-A (GB)
Title: Switching arrangement
Inventor: BLACKLOCK GERALD DOMINIC
IPC: H01H47/22
Filed: 1985-02-01
Abstract: An electrical switching arrangement comprises a solid state relay 4, an electro-mechanical relay 6 having contacts 5 to complete a by-pass across the solid state relay, and actuating means 14 and 16 such as a switch which has two sets of contacts to switch on the solid state relay and after a short dwell the electro-magnetic relay and to switch off the electro-magnetic relay and then after a short dwell the solid state relay. In the illustrated embodiment, the electromagnetic relay is bi-stable so on a first actuation of the means the electro-magnetic relay enters a stable conducting state whilst the solid state relay drops out on the cessation of the actuation. On a subsequent actuation the solid state relay is again rendered conductive before the electromagnetic relay is reset and again on cessation of the actuation drops out. The electro- magnetic relay is caused to alter state by a capacitor 17 which when the relay is not conducting is discharged through a relay contact and which when the relay is conducting is charged up through a resistor 18. <IMAGE>

Title: Refrigeration circuit pressure control
Inventor: VERONDINI ANDREA
IPC: F25B49/02
Filed: 1986-08-27
Abstract: In a method of regulating the operating pressure of a refrigeration circuit (1) in a multi-compressor refrigerating plant in which the compressors (2) are sequentially activated or deactivated with delays for the attainment of an optimum operating pressure (Po), the cut-in delay (K, H) of each compressor (2) is calculated in dependence on the difference between the actual pressure (P) of the circuit (1) and the optimum pressure (Po) to be achieved. The delay increases as the actual pressure (P) approaches the optimum pressure (Po). Such a method reduces hunting. When the actual pressure (P) is outside a band from 2Po to 1 DIVIDED 2Po the delay is held constant. If the actual pressure (P) differs from the optimum pressure (Po) by less than a tolerance  DELTA  then the number of compressors in operation remains unchanged. If all the compressors are found to be in a state of maximum utilization and the pressure P>/=(Po) +  DELTA , then an alarm is given and one or more evaporators (3) in the refrigeration circuit are disconnected to reduce the thermal load. <IMAGE>

Title: Detecting leakage of liquid from machines
Inventor: WEBB JOHN ARTHUR
IPC: G01M3/16
Filed: 1987-02-04
Abstract: The present invention comprises circuitry in combination with a liquid sensor element (Figs. 2 to 5) positioned externally to a protected appliance, so as to receive liquid leaking therefrom, and thereby providing an alarm and/or a safety response. The circuitry comprises two liquid detection circuits, the first activating an alarm B1 in the event of a small leakage. The second circuit activates a visual warning LED 1 and a relay RL1 in the event of a large leakage, thereby electrically disconnecting the protected appliance. The sensor element comprises mutually spaced electrode members (10, 11, 12; 20, 21, 22) provided in contact with a porous material (7, 8; 17), for receiving the liquid to be detected, the said liquid providing an electrical connection between the said electrode members. Electrical connection between a pair of electrode members closes the first electrical circuit to activate the alarm. Electrical connection between one of these electrode members and a further electrode member activates the visual warning and the relay which causes electrical disconnection of the appliance. <IMAGE>

Title: A semiconductor device for electrical overstress protection
Inventor: PATHAK VIJAY KUMAR
IPC: H01L29/87
Filed: 1988-05-27
Abstract: A voltage overstress protection device consists of a four-layer diode having, adjacent the central junction of the device, a buried region (3A) divided into a plurality of small regions to ensure an even distribution of energy dissipation across the structure. The buried region has a higher impurity concentration than the region (4) in which it is formed. The cathode (1) of the device may be perforated by shorting dots (6) of the material of the second layer (2) to determine the holding current of the device, and where this is done the small buried regions are aligned with parts of the cathode and not with the shorting dots. Two devices may be formed in opposite senses in the same body of semiconductor material and connected together in antiparallel to provide protection against voltage surges of either polarity. Two antiparallel pairs of devices may be formed in a single semiconductor body. <IMAGE>

Title: Rapid warm-up control system for process ovens
Inventor: STADEN ALFRED ALEXANDER
IPC: G05D23/19
Filed: 1991-01-16
Abstract: Rapid heating to full radiating power is achieved by applying to the heating elements a voltage which is at least 30% higher than their rated voltage for a predetermined period, eg. up to 3 minutes, or until a predetermined temperature is reached. Two 220 volt elements, which are normally connected in series across two phases of a 440 volt 3 phase supply, may initially have their series connection point coupled to the third phase of the supply. In alternative arrangements, three 80 volt elements initially each receive 240 volts and are then connected in series across the 240 volt supply (Fig 2), or reduction in effective applied voltage following warm up is achieved by burst-firing or phase-angle control of a thyristor. The oven may be a static oven for heating an adhesively-coated shoe sole, or an on-line oven through which motor car bodies are conveyed.   <IMAGE>

Abstract: Apparatus for use in turning inside out a stitched, hollow necktie assembly includes a guide comprising a hollow tube (2) of which part (4) of the wall is cut away over a shaped length extending from an intermediate part of the tube to a first end region thereof. A turning loop (7) is angled away from the first end region of the tube, the outer surface of the turning loop lying substantially within the projection of the outer surface of the tube along the axis thereof. The turning loop has a turning surface (27) facing generally away from the tube and an opposite surface (28) facing generally towards the tube.

Title: Packing machine
Inventor: BOEK ALFRED
IPC: B65B13/22
Filed: 1991-05-17
Abstract: The packing machine with a single drive motor (13 fig 1, not shown) is provided for laying band (11) around goods (10) to be packed, with the band being advanced by a drive roller (42). After a complete loop has been generated by the band (11), the band is reversed by a drive roller (43) in a reverse movement to be performed first at high speed. Then, the band (11) is tensioned by further reverse movement at a low speed. For the fast movement, there is provided a first drive branch (70) which always drives both drive rollers (42, 43) in common, a two-position lever (39) pressing the band (11) against either roller (42) or roller (43). A second drive branch (71), including a reduction gearing (80), is provided for tensioning the band (11), and drives reverse roller (43) only. A gearing member (81) of the gearing (80) is held fast by a stationary holding coupling (86). If the tension exceeds the braking moment provided by the holding coupling (86), the previously retained gearing member (81) is rotated. This rotation is detected by a sensor (88) which then initiates termination of the tensioning and moving of clamping jaw (25) into clamping position. Said holding coupling (86) is an electromagnetic brake adapted for electrically setting the holding moment within wide limits. If during initial tensioning, the tension exceeds a limiting value during reverse movement, the first branch is switched off and the second branch is switched on by a sensor (66). <IMAGE>
