Patent GB-2267457-A (GB)
Title: Manufacture of components from composite material
Inventor: POTTER MARK
IPC: B29C35/04
Filed: 1993-06-03
Abstract: Methods of and apparatus for manufacturing a component from composite material. The apparatus comprises a chamber (4) forming a cavity (2) which is divided into two parts by a membrane (16). Fluid pressure in the upper part (32) of the cavity pushes the membrane against the uncured composite material (12) positioned on mould tool (10), thereby ensuring the composite material conforms to the shape of the mould tools. Heat curable resin, which may be applied prior to or during the manufacturing operation, is cured by heater ring (34) which heats the composite material via the fluid and the membrane. The ratio of resin to composite material in the finished component may be controlled by varying the pressure exerted by the membrane during curing, surplus resin being drained off via the channels (50, 52). <IMAGE>

Patent GB-2296344-A (GB)
Title: Pressure control system
Inventor: NURNBERG ALEXANDER
IPC: F04B49/06
Filed: 1995-06-21
Abstract: In a system to control the pressure of fluid in a reservoir supplied by a compressor, the pressure of fluid P in the reservoir is sensed and the compressor speed is controlled accordingly. The compressor is run at its nominal speed when the reservoir pressure P<Pmin2, ie when the system is started up or when a significant withdrawl is made from the reservoir, and is run at a reduced speed when the pressure P is between Pmax and Pmin1, where Pmin2<Pmin1. The aim is to reduce power consumption by only operating the compressor at its maximum speed when a large pressure increase is required. <IMAGE>

Title: Polarisation-insensitive optical modulators
Inventor: GREENE PETER DAVID
IPC: G02F1/015
Filed: 1995-07-27
Abstract: The or each strained quantum well layer (12) of a quantum confined Stark effect modulator is provided with a substructure of substructure layers (12a and 12b, or 12c and 12d) not all having the same lattice constant. The thickness and composition of these substructure layers may be arranged to produce a differential strain that is asymmetric with respect to the mid-plane of the quantum well and so skews the hole wavefunctions for heavy-holes, HH1, and light-holes, LH1, in opposite directions. This enables the choice of composition designed to provide substantial matching of the E1-HH1 and E1-LH1 Stark shifts for one particular polarity of applied field, thereby providing a modulation facility that is substantially polarisation insensitive. Alternatively, the thickness and composition of the layers may be chosen to produce a symmetrical strain profile in which the same effect is provided, but for both polarities of applied field. <IMAGE>

Abstract: A level converter for a semiconductor memory device includes first and second input nodes SasB and Sas for receiving first and second voltages from a sense amplifier, first and second outputs DLAT, DLATB and a clock terminal Kpulb for receiving a clock signal. Each of a first pair of transistors MP1, MP3 has a channel connected between a power supply voltage Vcc and a respective output DLAT, DLATB and a gate connected to the first or second input nodes.

The power supply voltage Vcc is supplied to the outputs DLAT, DLATB when the clock signal is in a second state and to a latch supply node a predetermined time thereafter. A latch MP7-MP10 amplifies the potential difference between the outputs DLAT, DLATB, to be substantially equal to the power supply voltage, in response to the power supply voltage being applied to the latch supply node.

Title: Electrical fuses
Inventor: TALBOT KEVIN TREVOR
IPC: H01H85/0445
Filed: 1997-01-04
Abstract: A fuse device 20 has a first fusible conductor 32 arranged to carry electrical current during normal operation, and to blow at 50A, and a second conductor 38 arranged to be connected to earth via a diode 62 so that it will only conduct when the power supply to the circuit is reversed. Both conductors 32, 38 pass over a layer of combustible material, and the second conductor 38 has a narrow fusing section (56, fig 30) which is arranged to ignite the combustible material at relatively low reverse current. This blows the first conductor thereby cutting off reverse current through the circuit before it reaches a harmful level. The device may protect against reverse currents in circuits including FETs, eg. in vehicle electrical systems.

The label may be trapezoidal in shape (see figs 9-12) and may have at least one line of perforation 22. The second release coating may be discontinuous or formed as a pattern of dots. A label containing a fragrance-emitting compound between overlapping portions and a method of making overlapping labels are also disclosed.

Title: Distributor units
Inventor: MAKIN DAVID LEONARD
IPC: C02F1/00
Filed: 1998-01-13
Abstract: Distributor units for the treatment of effluent generally comprise a body member having at least one arm for the distribution of effluent over a filter bed. Typically these units are constructed of metal to provide the necessary strength and weight required, but as a consequence they are difficult to transport efficiently and also have problems due to corrosion over time.

The body member 10 comprises a pair of components 16 and 17, composed of plastics material which is initially hollow but can be filled with concrete 22 to provide the necessary strength and weight required. The ability to fill the hollow plastics components 16 and 17 on site allows for easy and cost efficient transport of the distributor from the manufacturer, and the plastics material is highly resistant to corrosion.
