Title: Automatic device to counteract imbalance in centrifuge loading - by temporary interruption of power supply permitting load redistribution
Inventor: DIDIER LAURENT
IPC: D06F33/48
Filed: 1980-09-02
Abstract: A device for countering imbalance in a centrifuge, partic. in the spin-drying phase of an automatic washing machine, comprises a circuit which temporarily interrupts the power supply to the motor when speed variations caused by non-uniform distribution of the load in the centrifuge are detected. The power supply to the motor, pref. a universal motor is regulated by a thyristor or triac which cops the power wave under the control of a limiter circuit. The current passing through the motor is monitored by a measuring device and compared with a control function by a comparator, whose output triggers the limiter circuit. The device prevents damage to the machine or its surrounding due to violent vibration caused by imbalanced loads, by automatically permitting the load to redistribute itself, or stopping the machine if the vibration persists.

Title: Transmission with regenerative braking - has independent coupling to drive shaft from engine and storage unit
Inventor: REGAR KARL-NIKOLAUS
IPC: B60T1/10
Filed: 1980-10-10
Abstract: The transmission for a vehicle allows the use of regenerative braking. It has a fluid drive to link the output shaft with a flywheel, or a similar energy storage, and a mechanical gearing between the engine and the output shaft. A summing gearing or differential combines the engine torque with the stored torque, while the hydraulic coupling can be operated independently. The hydraulic coupling can provide different gearing ratios so that the stored energy can be used at any speed, or without the engine torque.

Title: Measuring gauge for plastic surgeon - measures facial and nasal features using two coarse bevelled toothed plates sliding together
IPC: A61B5/107
Filed: 1981-01-09
Abstract: The implement is used in plastic surgery to take nasal measurements, comprising two toothed plates which slide relative to one another. The teeth are shaped and angled to suit the optimum number of facial angles and nasal roots. The sides of the teeth may be chamfered, the plates being attached by transverse pins through straight full length or intermittent holes. The method of attachment also guides the plates when sliding, the intermittent slot arrangement using pins through alternative sets of two slots. The pins may comprise two parts which screw or clip together. A vertical slide may be used to measure nose heights and a separating band may prevent chafing of the plates.

Title: High power triode valve with rod control grid - uses multiple focussed radial electron beams for high current and efficiency with cooled electrodes
Inventor: PEREVODCHIKOV V I
IPC: H01J21/14
Filed: 1981-02-03
Abstract: The coaxial valve operates at hundreds of kV and hundres of Amps. The valve consists of a cathode, a control electrode in the form of rods and a compartmentalised anode bounded by frames. The cathode is in the form of surface emitting slabs along the length of the tube mounted inside focus electrodes (9) in the form of slot cylinders at equipotential with the cathode. Each cathode produces a focussed electron beam directed radially between two control rods. There is a protection electrode in the form of a cylinder with longitudinal slits between the control electrode and the anode compartment. The anode frames have perpendicular auxiliary frames (16) in front of them, the edges of which form a window for the electron beam. The electrode rods, the anodes are hollow and the outer case is double walled, with a coolant (19) filling the spaces. The width of each cathode, the anode window width, the control rod to cathode distance and the depth of the anode compartment are all related by given inequalities.

Title: Fibrous bonded material esp. cellulose based - moulded by stabilising intermediate sheets resiliently mounted in mould
Inventor: KISS GUNTER H
IPC: B30B15/06
Filed: 1981-03-12
Abstract: An appts. for producing mouldings of fibrous materials contg. binding agent, esp. cellulose or lignocellulose materials, operates by application of pressure and/or heat with stabilising intermediate layers transmitting the pressure to the fibrous material. These intermediate layers are entirely or partly supported from the shaping mould or tool in a resilient manner, esp. by supports at points or along lines. The fixing elements for the stabilising intermediate layers may act elastically, in the manner of rubber or visco-elastically. They may be springs, rubber strips or plastics threads. In addition, adjustable pneumatic or hydraulic cylinders may be used. Used typically for the prodn. of woodchip prods. The appts. is intended esp. for prodn. of shapes where sharp changes of section result in a risk of local compression or stretching of the resultant moulded prod. thus weakening it.
