Title: Asynchronous automatic control circuit for mfg. process - gates starting inputs with safety inputs and combines with state detector output
IPC: G05B19/07
Filed: 1974-08-14
Abstract: A circuit for asynchronous automatic control of manufacturing processes and movement control receives a number of momentary inputs such as starting signals and a number of safety condition signals. From these signals are provided output signals. The control circuit comprises an input circuit which receives a number of momentary inputs which are gated with inputs received from safety circuits. Two of the gates form a memory circuit. The output passes into a NAND gate in a combining circuit with the output from a detector circuit in which a detector output is gated with a clock output. The gate outputs control a counter with a return to zero facility. The combining circuit controls a power output stage with light coupled amplifiers operating into output amplifiers with loads.

Title: Rotary engine driven by controlled explosions - uses powdered fuel ignited by electric sparking plug
IPC: F02B45/08
Filed: 1974-08-26
Abstract: The rotor is mounted on a shaft which rotates in a casing. The shaft has a sprocket which drives a camshaft by means of a chain. The cam operates a spring loaded plunger which pushes a charge of explosive powder is controlled by a rotary valve. When the charge is ignited by the sparking plug it forces down the bevelled end of a plunger and exerts a force against the surface of indentations in the periphery of the rotor, causing it to rotate. The exhaust gases escape by a hole drilled in the casing.

Title: Continuous mixing of starch solns to constant visocity - by using prod viscosity data to control coagulation
Inventor: PICHON FRANCIS
IPC: C09J103/02
Filed: 1974-09-05
Abstract: In the continuous prodn. of starch soln. to a constant viscosity by intermittently causing gelation of portion of a prefabricated milk of raw starch being pumped into a blending tank, the quanity of starch gelled is controlled as a function of the viscosity of the material in the mixing vat. The incoming starch contg. slugs of gelled material is promptly recirculated through a homogeniser together with material drawn from the bulk of the liquid in the mixing tank. The blended re-entry material is discharged close to an agitator which redistributes the contents within the mixing tank. The produce viscosity is determined either via monitoring the liquid level as the tank discharges through a calibrated restriction or by passing the outlet material via a viscometer positioned over a constant level outlet. Gelation is effected by injection of alkali.

Title: Division system for binary numbers - uses register cells to store divisor and multiplicand and operates on parts of operands of greatest weight
Inventor: HUBERT BELA
IPC: G06F7/535
Filed: 1975-02-19
Abstract: The system is for dividing binary members and uses a register which stores the divisor and the multiplicand. The parts of the operands of greatest weight are acted on successively in each partial operation in order to estimate the partial quotients in advance. A logic value is associated with each possible combination of the register cell contents and converted into a first signal, with these signals stored in a permanent memory. The contents of the latter can be transferred to a selection network addressed by the output signals from the rest of the cells to obtain the first signal corresponding to the actual contents of the cells. A sign signal indicates the sign of the partial operation.

Title: Efficiency tester for motor vehicle dampers - is performed by recording oscillation when body is released from height
IPC: G01M17/04
Filed: 1975-03-12
Abstract: Motor vehicle dampers are checked without the need for removing them from the vehicle. This is performed by recording the oscillation of the body when released from the fully extended height of the damper. This recording is compared with that from a new damper. The damper (1) is tested by raising (3) the bodywork (2) fully to extend each unit. A cable (11) is attached (16) to the body and passes over a pulley (12) to a return spring in a chart recorder (4). Action of the pulley is geared down (13, 14) to drive the stylus (15) on a chart (18). Recording is synchronised (6) to start the chart motor (17) when the body lift (3) is rapidly lowered.

Title: Regeneration of active carbon - esp. from waste water purifcn. using electrical resistance heating
IPC: H05B3/60
Filed: 1975-04-03
Abstract: In the regeneration by heating of active carbon used for cleaning contaminated liqs., the spent carbon particles are introduced into the space between electrodes arranged at a distance from each other and an electric current is passed between the electrodes via the particles. The particles are thereby heated and regenerated, partic. as a result of the heat evolved due to the electrical resistance of the particles themselves and of the contact resistance between particles. No steam or fuel gas is required. Loss of active carbon by attrition is reduced by the use of a stationary (as opposed to a fluidised) bed. The cost of the installation is relatively low. The temp. profile in the bed can be easily controlled. Direct current, single-phase or three-phase alternating current can be used, and the plant can work continuously or discontinuously. A homogeneous prodt. is obtd.

Title: Sensitisation of composite fabrics to hot transfer printing - by multistage treatment with sensitising agents
IPC: D06P5/28
Filed: 1976-03-31
Abstract: Treatment of tissues prior to hot transfer printing where the tissue are made from a mixture of fibres of material receptive to such printing (polyester of acrylic filaments) with fibres of materials not receptive to such printing (natural or regenerated cellulosic fibres or mineral fibres). The tissue is treated with a print sensitising agent, specifically, an acrylic vinyl polymer or copolymer, first by dipping treatment and then by >=1 applications of a pattern of further deposits of the sensitising agent using flat or rotary printing techniques to match the sequent hot transfer printing pattern. The enhanced sensitiser levels allow the transfer pattern to be deposited and bonded with satisfactory evenness and contrast with the background.
