Title: Mechanised malting installation for breweries and distilleries - has grain stirring screw which can be raised clear of grain
IPC: C12C1/15
Filed: 1977-02-16
Abstract: Grain is charged into a cylindrical pan, heat treated and turned over in the pan for controlled germination and then discharged via a pan outlet. Turning of the grain is by a conveyor screw suspended from a radial beam rotating about the axis of the pan. The conveyor screw turnover assembly is pivotally mounted about the longitudinal axis of the radial beam. The beam carries a mechanism to control the pivoting motion of the turnover assembly to swing it from a suspended, operative position, to an inactive position clear above grain in the pan. The pivoting mechanism pref. comprises a jacking screw actuated by a gerard electric motor. The turnover assembly can pref. be traversed along the radial beam by a motorised rack and pinion mechanism. The radial beam can pref. be rotated at different speeds so that the linear speed of the turnover screw through the grain is the same at different radii on the beam. Cf. previous, mechanical maltings, the installation provides efficient loading, mixing and discharging with a less complex and more economical construction. All mechanical movements of a complete malting cycle can be programmed to follow a sequence automatically.

Title: Preventing short circuiting between anode and moving mercury cathode - by system which moves anode away when it gets too near the cathode
IPC: C25B15/06
Filed: 1977-05-05
Abstract: The appts. comprises a means of detecting when a predetermined critical position of the anode relative to the cathode is reached, connected to a means of moving the anode relative to the cathode. The displacement arrangement comprises a spring normally compressed between a fixed support and a second support fixed to the shaft carrying the anode. This second support is kep in its position by a slide which can move horizontally in a groove. An electromagnet, activated by the detector, causes the slide to move away from the support so that the spring extends, pushing up the shaft bearing the anode and thus removing it from the vicinity of the cathode. The prevention of a short circuit reduces wear on the electrodes and prolongs their life. The appts. is simple and robust and works instantly, without the time lag in previous devices. Used in brine electrolysis cells.

Title: Vehicle Doppler velocity meter - includes ultrasonic meter independent of wheel slip effects and applies to all:wheel drive vehicles
IPC: G01S15/60
Filed: 1977-06-10
Abstract: The instrument is for measuring the speed of a vehicle, especially a vehicle with drive on all its wheels, avoiding error due to slip. A generator (G) generates signals at a steady supersonic frequency, which are directed towards the ground at an angle of incidence less than 90 deg. from a transducer (T) and received back after ground reflection by a receiver (R). A signal shaping circuit receives the signals via an amplifier (A2) to convert them to sinusoidal signals of constant amplitude at the transmitted frequency. An amplitude multiplier (M) receives the signals from the generator directly and those from the amplifier (A2) to generate a signal representing their product, which is passed to a low pass filter (F2) which feeds out a sinusoidal signal of frequency representing the difference between the signal frequencies. This is taken to a converter (MS) to generate a signal of amplitude proportional to this frequency and therefore to the speed of the vehicle.
