Title: Thrust generating device utilising coriolis force - rotors with radially sliding masses impart force to structure
IPC: F03G3/00
Filed: 1975-02-17
Abstract: The device (1) has a housing (2) in which two parallel shafts (6) and (7) rotate in opposite directions. The shaft (6) has a number of radial arms (10) arranged in diametrically opposite pairs along the length of the shaft. Specially shaped masses (3) can move radially along the arms (10). The shaft (7) has similar masses (4) sliding on arms (11). Each shaft and mass assembly is enclosed in a cylinder (16, 17) mounted eccentrically to the shaft axis. The shafts are rotated in opposite directions and the eccentric cylinders cause the masses (3, 4) to oscillate radially, subjecting the masses (3 and 4) to a coriolis force and the reaction to this force is imparted to the structure.

IPC: H01L21/60
Filed: 1975-05-21
Abstract: 1502965 Welding by pressure; welding electrical contact PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 May 1975 [21 May 1974] 20840/75 Headings B3R and B3A In a method of welding a wire 9 (e.g. gold) to a semi-conductor body 1, an electric spark discharge between an electrode 10 and the end of the wire 9 melts the wire to form a ball 11 below a recess 8 in the welding surface 6 of a welding tool 5, preferably an ultrasonic sonotrode, whereupon the tool 5 presses the ball 11 on to a contact place 2 of the semi-conductor body 1 to produce the weld. The welding tool 5 also produces a weld between the wire 9 and a supply conductor, without the formation of a ball 11 (Fig. 6, not shown). The electric spark discharge may be provided by way of a transformer fed by a discharge capacitor, the discharge time being less than 5 msec. and the energy of the discharge (hence the size of the ball) determined by the capacitor voltage. The recess 8 can either be a groove transverse to the wire 9, which is fed to the welding surface by way of a hole in a separate plate (not shown) or an aperture 7 in the welding tool, or a cone having an apex of 120 degrees. On completion of the weld to the supply conduction the tool remains in its welding position as the wire is snapped by pulling.

Title: Solar water heating appliance - consists of transportable foldable plastics bag with heat-insulation
Inventor: KLEINWACHTER HANS
IPC: F24S10/70
Filed: 1975-07-31
Abstract: The appliance consists of a foldable plastics bag, which may be positioned in the water circuit to be heated. The water is in contact with the floor layer of the bag, which absorbs the solar radiation passing through the clear, transparent cover layer, formed as a light window. The base of the bag is heat insulated by a foldable air bubble insulation foil, which is directly connected to the absorbent layer, and which also serves as a mechanical protection. The transparent cover consists of a double layer, which may contain an intermediate insulating air layer, in case of low external temperatures. Floor and cover are connected via comb interlocking welded seams. This causes the water to circulate, and maintains the appliance e.g. air bed, stable on slopes.

Title: Amorphous coatings or covers on retread strip - when recovering tyre carcasses, for uniform distribution of external pressure
IPC: B29C67/00
Filed: 1976-06-10
Abstract: Use of an amorphous coating or pad of paste, powder or liquid over the patterned surface of a prefabricated retread to be consolidated by use of vacuum cover against the surface of a suitably prepd. tyre carcass. The coating or pad acts as a pressure transfer medium to the tread surface during lay-up of the tread, opt. with underlying supportive plies and cords, and during hot vulcanisation under pressure. The coating/pad penetrates into the grooves of the tread pattern to ensure distribution of the external pressure to the substrate layers of the tread strip, thus inhibiting alignment displacement or tread distortion.

Title: Pressure compensated flow rate restrictor valve - has variable throttle controlled by sprung plunger with leakage groove and bypass
IPC: G05D7/01
Filed: 1976-10-20
Abstract: The flow valve has a pressure-operated control plunger. The valve consists of housing (10) with an inlet (12), lateral bore (14) and outlet (16). The outlet channel (16) contains an adjustable throttle (18), and the lateral bore (14) contains the automatic pressure regulating spindle (20) fitted at one end with a shoulder (22) which serves as a piston as well as a throttle for controlling the flow rate.

Title: Thermal protection of shaft furnace walls in smelting - using metal plates attached to cooled tubes
Inventor: ZHERDEV A V
IPC: F27D1/12
Filed: 1977-03-22
Abstract: Metal plates having a height to width ratio of 2 to 3:1, which are used for thermal protection of the shells of shaft furnaces for smelting, are made up of individual bars, of which the width exceeds the height. The surfaces of the bars facing the furnace shell are provided with recesses into which U-shaped coolant-conveying tubes are fitted. A thermally conductive material is placed in the recesses to improve heat transfer from the plates to the coolant flowing inside the tubes. Elements are located between the recesses for attaching the bars to the tubes. Further elements are welded to the tubes so that they can be secured to the furnace shell. Differential thermal expansion in the vertical direction can be taken up without developing the material stresses which occur in one-piece plates. The life of the plates is increased and the time between repairs is extended. The probability of dangerous situations arising is reduced.
