Title: Phase-controlled thyristor circuit
Inventor: MARLOWE STEPHEN
IPC: H03K17/795
Filed: 1987-12-18
Abstract: A dimmer circuit for use with a three phase supply comprises, for each phase, a ramp generator (36, 42) triggered by a zero crossing detector. The zero crossing detector includes an opto-coupler. In one arrangement, the opto-coupler has a photo-transistor (30) responsive to a pair of light emitting diodes (28) which sense the voltage of the supply. In another arrangement, the pair of light emitting diodes are replaced a single light emitting diode and a full wave rectifier. The output of this ramp generator is connected to two comparators which also receive voltages from control units. The output of each comparator is supplied to a firing pulse generator which includes an opto-triac. The firing pulse generator supplies trigger pulses to the gate of a triac connected in series with a lighting unit. <IMAGE>

Title: Forming busbars on electroconductive coatings on glass by arc spraying
Inventor: EVASON JOHN
IPC: H05B3/26
Filed: 1988-02-18
Abstract: This invention relates to glass (1,4) carrying an electroconductive coating (7) and, in particular, to a method of applying bus bars (3,6) on the glass (1,4) to establish electrical contact with the coating (7) and to coated glass (1,4) provided with bus bars (3,6) in accordance with the invention. The method of applying the bus bars (3,6) to the electroconductive coating (7) involves arc spraying molten metal e.g. aluminium on to the coated glass (1,4) in the required configuration which can be defined by either placing a stencil over the surface of the coated glass (1,4) or using adhesive tape (5) to define the required configuration, and then spraying the molten metal. Aluminium has been found to be a most suitable metal for the bus bars and this can be oversprayed with a layer of copper, zinc, tin, a tin alloy, stainless steel, nickel, brass or copper nickel alloy if required. In certain circumstances, for use in architectural applications for e.g. electromagnetic shielding purposes, the bus bars are wrapped around the edge of the glass to provide electrical contact means when the glass is used in a laminate or a double glazing unit.

Title: Fabricating structures
Inventor: PEMBERTON JOHN MICHAEL
IPC: E04B1/16
Filed: 1989-03-28
Abstract: A method for the construction of civil engineering structures in which a membrane 32, for example of flexible material, is supported by water, air or similar pressure P or by other supporting structure and a ferrocement laminate is constructed on the membrane, by successive application of material. After the laminate structure has been built up to sufficient strength, the pressure P may be removed, together with the membrane so that the structure is self-supporting for subsequent layers. The illustrated laminate comprises an unreinforced gel layer 2, followed by five reinforced layers 3 to 6 and 33, and a final top coat layer 7. The reinforced layers may be fabricated by applying a layer of mortar and, while still wet, pushing reinforcement such as expanded metal, into the mortar. A web of reinforcement wires or rods may be provided before the ferrocement is applied. In embodiments, a sequential casing arrangement is described. When the membrane 32 is floated on water, floating docks, pontoons, barges, or caissans may be constructed. <IMAGE>

Title: Unloader arrangement for a screw compressor.
Inventor: LINNERT PETER J
IPC: F04C18/16
Filed: 1992-07-20
Abstract: An unloading arrangement for a rotary screw compressor includes discrete and different unloading apparatus associated with male and female rotors 18, 20 respectively. The unloading apparatus associated with the male rotor 18 is an axial piston continuous unloader 54 movably disposed in a bore 50 which is in flow communication, through a series of ports 52 with the compressor's working chamber 36. The unloading apparatus associated with the female rotor 20 is a step unloader 46 which, when opened, unloads the compressor in a single, relatively large capacity step. The compressor is therefore capable of being unloaded both in a continuous fashion and in a discontinuous, stepwise fashion. By duplexing compressors of this type, continuous capacity modulation of a multiple compressor system is made available over a large operating range without the employment of compressors unloaded by slide valve mechanisms. The compressor(s) may form part of a refrigeration system. <IMAGE>
