Patent GB-2141179-A (GB)
Title: Vapour turbine power plant
Inventor: BRIERLEY ROGER STUART
IPC: F01K9/00
Filed: 1983-05-07
Abstract: The plant is of the closed-cycle type and comprises special vaporisation and condensation units in combination, designed to achieve recycling of the Latent Heat of the working fluid. The vaporisation unit, via special sub-systems which cause vaporisation of the working fluid to occur under reduced pressure resulting from entrainment with separated vapour flows, achieves the dual purpose of maximising the efficiency of the vapour energy production, whilst a heat transfer fluid becomes sufficiently cooled down under supercooling to then act as a condensing fluid in the condenser unit wherein absorption of the latent heat occurs to then become recycled, with further supplementary heating as required. The special sub-systems in the vaporisation unit involve a fractionalised vaporisation technique and a two-stage vaporisation system, coupled with working fluid atomisation and parameter optimisation, whilst the condensation unit contains an interrelated fractionalised cooling system in which the working fluid becomes fed back to the vaporisation unit at optimised temperatures. <IMAGE>

Title: Determining fuel and/or air distribution in a multi-cylinder engine
Inventor: ARMSTRONG JAMES DAVID
IPC: F02D41/14
Filed: 1983-08-25
Abstract: A method of determining mass flow rate of fuel supplied to one cylinder of a multi-cylinder internal combustion engine comprises interrupting the ignition of the cylinder during selected cycles so as to allow unburnt charges from the cylinder to enter into the exhaust system and monitoring the change in hydrocarbon level in the exhaust system caused by the interruption. The invention also proposes determining the mass flow rate of air by first setting a rich mixture to use up substantially all the oxygen and then determining the change in oxygen content of the exhaust gases as firing is periodically interrupted in the individual cylinders. The sparks to a cylinder are interrupted by means of a programmable divider 42 which acts on a gate 32 to prevent triggering pulses from a shaft encoder 30 from reaching the ignition circuit 34. The hydrocarbon or oxygen level is monitored by sampling at a point [16] in a cold part of the exhaust manifold and feeding the samples into a gas analyser. <IMAGE>

Title: Method for calibrating cylindrical tanks
Inventor: SCHIOTT YNGVAR
IPC: G01F25/00
Filed: 1983-06-10
Abstract: In connection with a method for calibrating cylindrical tanks for determining the volume thereof, it is suggested to establish a number of survey stations (A, B, C) for the fixing of a base polygon by measuring the distance between said stations and the angles therebetween. From a first survey station (A) there are established directions, level by level, to a first tankwall profile (T) and a second tankwall profile (T), as well as the direction to a second survey station (B) for orientation in the base polygon (A, B, C). Corresponding measurements are taken from the other survey stations for on the basis of the direction observations to determine the angle (TAT) between every pair of tankwall profiles at the same level, so that for every level there can be calculated a mean radius (r0), which constitutes the basis for the calculation of volume.

Title: Handling machine-coded instruction words
Inventor: SLAVENBURG GERRIT ARY
IPC: G06F9/318
Filed: 1985-01-11
Abstract: The invention relates to a method of handling machine-coded instruction words. The instruction words each comprise an opcode part and an operand descriptor part. The collection of opcode parts is subdivided into two classes. A first class comprises normal opcode parts which are processed in known manner, while a second class comprises virtual opcode parts which are processed in a particular manner. This particular manner implies inter alia that the instantaneous program counter position is temporarily stored in a supplementary program counter register and that a memory address is determined. When an opcode part of the virtual type is decoded the associated operand descriptor part is loaded into an index register. The descriptor part of an instruction with virtual opcode is handled by a series of instructions, the first of which is located at the said memory address. <IMAGE>

Title: Position coordinate determination device
Inventor: SNYDER EDWARD J
IPC: G05B19/409
Filed: 1986-04-04
Abstract: A position coordinate determination device comprising a data tablet having a grid of conductors 2,4 inductively coupled to magnetostrictive elements 8,8' defining an X-Y coordinate system. Current pulses are induced in respective X and Y conductors in response to the generation of flux by the coil 24 of a pointer 22 positioned adjacent the tablet surface. The current pulses induced in the conductors 2,4 in turn induce a pair of oppositely propagating strain waves in each magnetostrictive element 8,8'. Each magnetostrictive element has a pair of sensors 11,13 arranged at the respective ends thereof for outputting a pulsed signal in response to the detection of the arrival of each respective strain wave. A count in four counters is started simultaneously with the generation of flux by the coil of the pointer. Each count is separately stopped upon receipt of the pulsed signal output by the respective sensor. The four counts represent the respective times of travels of the four strain waves. The four counts and two reference data representing the time of travel of strain waves under standard conditions are used to calculate the true X and Y coordinates of the pointer position. <IMAGE>

Title: Solar heater
Inventor: PRIESTLEY ERNEST
IPC: F24S10/70
Filed: 1986-10-09
Abstract: A solar heater has a tubular copper pipe deformed along one longitudinal line to form two concentric semi-tubular walls (12, 14) spaced-apart by a distance of 4mm. The radially inner wall (12) is concave in cross-section and this provides a greater surface area for transferring energy from the solar radiation to the fluid within the pipe. Since the walls (12, 14) are closely spaced, the pipe contains only a small amount of water which therefore may be heated to a higher temperature than in existing heaters. The pipe is embedded in an elongate block (16) of insulating foam, and the foam and the pipe are both enclosed in a plastics film (34) to increase the absorption of energy from the solar radiation. <IMAGE>
