Title: Brake valve for hydraulic brakes - spring loaded sleeve on actuator spindle acts as valve seating and piston
IPC: B60T13/18
Filed: 1974-01-04
Abstract: A vehicle braking valve, with its spindle (20) connected to the brake pedal linkage, has a large diameter portion (20) of the spindle followed by a reduced diameter portion with a sloping end (23) acting as a valve member against a seating in a ring (30) held back by a main spring (35) and with a smaller spring around the smaller diameter portion.

Title: Cup or pot handle manufacture - uses extruded ceramics material with layer of strip plastics material on its surface
IPC: B28B11/00
Filed: 1974-04-22
Abstract: Handles are manufactured from a plastic ceramic material for cups and pots by extruding the ceramic material to form a strand having the cross-section of a handle and lying on it a foil-strip of plastic moved with the speed of extrusion and in the direction of extrusion. The strand and the foil-strip are divided into pieces which are deformed to the shape of handles with the foil-strip on the side of the strand which forms the outer periphery subjected to the greatest strain during the deformation of the pieces. The foil-strip is removed before th cutting to size of the attachment surfaces of the handles. The handle is deformed after the strip has been removed and before the cutting to size of the attachment surfaces by the extrusion technique, e.g. to a handle with continuously narrowing cross-section. In shaped and quality the extruded handle is the equal of a moulded handle, whilst the disadvantages of the casting process are avoided.

Title: Application of clay for beauty care or bodily hygiene - without overflow of paste outside region of application
IPC: A61Q19/00
Filed: 1975-02-06
Abstract: Clay is applied for beauty care and bodily hygiene by means of a sheet of tarlatan, a sheet of carboard having a density of 120 mg/m2 known as 'Bulle' (RTM) paper, a non-woven cellulose-base fabric known as 'Intissel' (RTM) paper, powdered clay inserted between the 'Bulle' paper and the 'Intissel' paper, and a seam on all four sides to close the whole assembly. The length and width of the pack may vary according to use. The quantity of powdered clay inserted is sufficient to obtain a paste having a thickness >=50 mm. when it has been soaked with water. The 'Intissel' paper allows high penetration of the paste, while the 'Bulle' paper acts as a barrier to the paste and is reinforced by the tarlatan.

Title: Static frequency converter for AC - provides three phase facility without using intermediate DC stage and operates by sequential switching
Inventor: UYEN THUY NGUYEN
IPC: H02M5/27
Filed: 1975-02-26
Abstract: A static frequency converter gives a variable frequency output from a fixed frequency input without an intermediate D.C. stage. The converter load is fed from an A.C. supply by a transformer whose windings are arranged and switched by a control circuit. The control is cyclic in that during a given period in each cycle each load phase is fed successively by each of the input phases from the converter network. The load phase circuits are hence fed by a changing combination of phase selections. Switching is carried out by three separate control circuits closing their associated switches for some fraction of the set period (Tm) during each cycle.

Title: Hydrogen production for power source - involves thermal decomposition of water to generat plasma supplying hydrogen fuel
IPC: F02M33/00
Filed: 1975-02-25
Abstract: The system treats either a mixture of water and fuel, such as petrol, gas-oil, alcohol, ammonia or any hydrogenous product-or pure water. It causes under certain physical conditions a thermochemical decomposition of the water in the mixture, producing a plasma to generate hydrogen. This is then utilised directly as a source of power in an internal combustion engine, of the piston, turbine, rotary or jet type, or in a heating system. The mixture can be admitted at a variable rate into the equipment and the percentage by weight or volume of the water can vary from 0 to 100% after thermal conditions representing cruising speed have been reached.

Title: Control for hydraulically-operated group of cutters - maintains cutters on combine at required height
IPC: A01D41/14
Filed: 1975-06-30
Abstract: The harvester cutters are connected by means of spring tension and two tension springs to the control lever. Between the two tension springs is a switch with a neutral setting or - affected by one of the two tension-springs - a top or bottom setting, whereby the switch operates the switch for the dropping valve or that for the lifting valve. Independently of the cutting height set by the lever, an extra lever can alter the position of the switch. If this extra lever returns to a neutral position, the pre-selected cutting height returns as a result of the sprung equilibrium between the two tension springs. The extra lever has end-stop pieces.
