Title: Electro-optic switching device using the pyroelectric effect
IPC: G02F1/01
Filed: 1980-10-23
Abstract: An electro-optic switching device using the pyroelectric effect consists of a waveguide with a layer of pyroelectric material on its surface. When the pyroelectric is energised equal and opposite charges are induced on the surfaces of the waveguide resulting in a field in the waveguide. This field causes the plane of polarisation of light passing through the waveguide to be rotated, so by having suitably configured polarisers at each end of the waveguide, a charge of transmitted intensity occurs. The device can be used as an intruder detector or it can be used as a light amplifier, being analogous to an F.E.T. with the pyroelectric as the gate, the light source as the source and the output as the drain. <IMAGE>
Patent GB-2065827-A (GB)
Title: Gas spring
IPC: F16F9/00
Filed: 1980-12-11
Abstract: A gas spring for opening and supporting a vehicle includes means for arresting the piston rod in one terminal position. These arresting means comprise pressure relief valve means 12 which are closable by a prestressing member 15 and can be opened by a pressure differential existing between the two compartments 4, 5. The prestressing force exerted by the prestressing means is responsive to the axial position of the piston rod in such a way that the prestressing force is increased when the piston approaches that end of the cylinder member at which the piston rod member is to be arrested. Due to this design the prestressing force decreases when the piston rod is moved from its arrested terminal position towards the other terminal position so that a substantial manual force for overcoming the arresting action, is only necessary during a short section of the total path of the piston rod with respect to the cylinder. <IMAGE>

Patent GB-2095390-A (GB)
Title: Low pollution method of burning fuels
IPC: F23L7/00
Filed: 1981-03-24
Abstract: A low pollution method of burning a fuel comprises gasifying the fuel in a gasifier bed containing particles which are fluidized by a fluidizing gas containing substantially no inert components. The resulting combustible gas is burned with air diluted with nitrogen to reduce NOx formation. In addition, NOx production from the nitrogen content of the fuel is reduced as a result of the gasification of the fuel to combustible gas before combustion with air. Preferably the gasifier bed contains CaO to fix sulfur from the fuel as CaS. In one embodiment, the gasifier bed (51) contains CaSO4 and the fluidizing gas contains H2, inter alia, which mediates the transfer to the fuel of chemically-bound oxygen from the CaSO4 (which is thereby reduced to CaS). Particles containing CaS are passed to an oxidizer bed (72) wherein they are fluidized by air. The CaS is exothermically oxidized to CaSO4 by extracting oxygen from the air which is thereby heated and substantially exhausted of oxygen. The hot CaSO4 is transferred from the oxidizer bed (72) to the gasifier bed (51) for gasifying further amounts of fuel, and the hot oxygen-depleted air is cooled by heat exchange (in 80) with boiler feed water, and then added to combustion air (in 69) to reduce the peak flame temperature when the combustible gas is burned at the burner (56) thereby mitigating NOx production from reactions in the flame between oxygen and nitrogen from the atmosphere. Because the fuel is gasified in the absence of diluents, the gasifier bed (51), combustible gas conduit (55), the burner (56) and gas circulation fans are of reduced sizes. The low pollution combustion of the fuel necessitates no modification of the furnace or boiler (84) and results in no increase in its operating costs or reduction in efficiency.

Patent GB-2099634-A (GB)
Title: Impedance matching circuits
IPC: H03H7/38
Filed: 1981-05-21
Abstract: An impedance matching circuit is provided for enabling an amplifier to feed a load, e.g. an antenna or a higher power amplifier, in a particularly efficient manner. It is often desired to match the output impedance of an amplifier to that of the load to which it is coupled, but this can result in the loss of power in an impedance matching circuit. In the present invention, two amplifiers 11, 12 receive the same input signal and after amplification the amplified signals are combined to provide a single output signal. The output impedance of one amplifier is equal to the reciprocal of the output impedance of the other amplifier. An output source impedance RS is coupled to the two amplifiers and it has a value equal to the nominal impedance of a load RL. However, when the impedance of the load equals that of the source impedance substantially no power is dissipated in the source impedance. Many loads have an impedance which varies in frequency and it is only at those frequencies for which the load impedance does not equal the source impedance that power is dissipated in the source impedance itself. <IMAGE>

Patent GB-2078459-A (GB)
Title: Leakage current compensation for dynamic MOS logic
IPC: H03K19/096
Filed: 1981-06-15
Abstract: A leakage current compensation arrangement which can compensate for loss of charge at the output of a logic network realized in dynamic MOS technique, which loss is caused by the occurrence of brief leakage currents in the network during a logic operation. The use of this leakage current compensation in 2-phase dynamic MOS-logic makes it readily possible to handle 2 logic functions per clock period, which clock signals may be each other's inverse, which results in faster operation and a simpler design of the logic. As shown, bootstrap capacitor T11 raises the potential at node Q when phi 2 goes high to compensate for transient leakage which could be caused by T3 conducting while node P reaches its steady-state potential. If no such transient occurs, and no discharge path is established, the potential of node Q will remain at the raised level, or else be discharged, depending on the inputs A,B. <IMAGE>
