Title: Vapour sensor
Inventor: KEMBER PETER NICHOLAS
IPC: G01N27/414
Filed: 1983-08-19
Abstract: A vapour sensor comprises an insulated gate field effect transistor having a layer (14) of a vapour absorbent material between the gate electrode (15) and the gate insulator (13). The gate electrode is porous or patterned so as to allow vapour to be absorbed by said material (14) which, in response, undergoes a change of bulk dielectric constant. This causes a change in gate capacitance of the transistor resulting in a detectable change of electrical conductivity in the drain source channel. In the case of a sensor responsive to water vapour the layer (14) may be of a hydrophilic polymer e.g. a hydrogel. In the case of a sensor responsive to a basic or an acidic vapour the layer (14) may be respectively of an acidic or a basic polymer. <IMAGE>

Title: Fuel injection systems for IC engines
Inventor: KANESAKA HIROSHI
IPC: F02B3/06
Filed: 1984-01-25
Abstract: Fuel is supplied to an injector 4B by a fuel injection pump 4A driven by a crank mechanism 50-55, Fig. 1, the injector 4B comprising an accumulator 16 from which fuel is supplied to a space 15 surrounding an injection valve 12 which is caused to open by a pressure drop in the fuel passages 5a, 7a, 7c supplying the accumulator 16 and, via fuel passage 8a, the space behind the injection valve 12. Closure of the injection valve 12 is caused by the drop of pressure in the accumulator 16. The pressure drop in fuel passages 5a, 7a, 7c is caused by actuation of valve 17. In a distribution type injection pump, Fig. 5 rotation of drive shaft 107 causes a crank- shaft 122 to rotate about a vertical axis and, by way of level gears 113, 114, 119 and 125, about a horizontal axis.

Title: Decoding run length encoded data
Inventor: HUNT DAVID JOHN
IPC: G06T9/00
Filed: 1984-05-14
Abstract: A run-length decoder produces output signals in groups, each group being output in parallel from register 20. The decoder includes a position register 23 which indicates the position within a group, of the latest transition between signal values. The contents of this register are added to the incoming run-length code so as to calculate the number of groups to be output up to the next transition, and the position within the group of that next transition. The calculated number of groups is then output while counter 22 counts to zero, whence a transition is introduced into the calculated position in the current group to be output, and register 23 is updated. <IMAGE>

Title: Fluidized bed combustion apparatus and method of carrying out fluidized bed combustion
Inventor: JOHNSON WILLIAM BENEDICT
IPC: F23C10/02
Filed: 1985-01-16
Abstract: The invention includes the steps of, and suitable apparatus for, maintaining a fluidized bed of fuel particles, optionally containing relatively dense bead-like particles of inert solid material dispersed throughout the fluidized combustion bed, circulating the particles through heat exchange means separated from the combustion bed and returning the particles to the fluidized bed where they are discharged from an arched heat exchange outlet to direct the returning bed constituents in a generally horizontal direction directly over the combustion bed for generating increased circulation in the bed. The bead like particles act as a heat exchange medium and a grinding agent for the fuel particles.

Title: Manufacture of ammonia and related products and methods of and means for producing power and cooling
Inventor: YOGEV AMNON
IPC: C01C1/26
Filed: 1985-04-26
Abstract: In the manufacture of ammonia and related compounds, energy consumption is reduced by (i):- directing ammonia gas through one feed line, and carbon dioxide gas and steam through another feed line, into a closed reaction chamber to form solid ammonium carbonate, resulting in a reduced pressure in the chamber, which reduced pressure can be used to drive heat engines in the reactant feed lines; (ii) an alternative pathway is constructed along part of the potassium carbonate loop. Carbon dioxide gas and water vapour formed by the heating of the potassium bicarbonate flow through a heat engine and are cooled and recycled. The reactant gases may be liquefied and revaporised in the event of reactor shutdown, and heat-exchange means may provide at least a portion of the heat of vaporisation of the liquefied reactants. The heat-exchange means can thus produce a refrigerating fluid as a result of the vaporisation of the reactants.

Patent GB-2189912-A (GB)
Title: Data processing system; A.C. motor control
Inventor: BIRD PHILIP HARVEY
IPC: G06F9/22
Filed: 1986-04-30
Abstract: A data processing system includes a microcomputer (6) which has a single interrupt signal input pin (INT/TO) and responds to a high-to-low transition on this pin rather than the mere presence of a "low" signal thereon. In order that two interrupt signal sources (10, 11) can be employed without the substantially simultaneous generation of interrupt signals by both resulting in only one interrupt actually being serviced, the outputs (13, 14) of these sources are connected to the set inputs (19, 22) of respective set- reset flip-flops (21, 24) the outputs (20, 23) of which are connected to the interrupt input pin via an OR- function circuit (17). The active low output signal of the OR-function circuit can be overridden by the application of an override signal to a further input (29) of this circuit. When an interrupt signal occurs the microcomputer first tests by means of a test pin (T1) whether a particular one (21) of the flip-flops is set. If it is it performs an interrupt routine branch corresponding to the relevant source (10). If not it performs a branch corresponding to the other source (11). At the end of each of these branches it generates a logic "0" pulse at a corresponding one of a pair of further outputs (P06, P07) which is connected to a reset input (31 or 32) of the relevant flip-flop and also applies a logic "0" pulse to the override signal input (29) of the OR-function circuit, thereby resetting the relevant flip flop and also generating a new high-to-low interrupt signal transition if the other flip-flop has also been put into the set state. <IMAGE>

Patent GB-2194399-A (GB)
Title: Fluorescent light control circuits: refrigerated cabinets
Inventor: HARDING PETER JOHN
IPC: H05B41/42
Filed: 1986-06-24
Abstract: The control circuitry causes a first voltage to be applied to the fluorescent light (18, 20), (Fig. 1), for a predetermined time sufficient to allow the light to reach a stable operating state, whereafter a second voltage, lower than the first voltage, is applied to the light. The use of such circuitry permits high efficiency fluorescent tubes to be used in, for example, refrigerated cabinets, (Fig. 1), where high levels of illumination are not required, and also reduces the heat output from the tubes. When a timer 38 times out, a circuit IC3 energises a relay RL1 or RL2 to switch the light supply from a direct mains connection to one or the other of two lower voltage taps 60, 62 providing a choice of two values for the second voltage in dependence on the state of a logic control input 36 which may be applied manually or by an energy management system. The tubes may be shielded against air turbulence within the refrigerated cabinet by strips of transparent material. <IMAGE>
