Title: Silent working liq. control valve - has convex support face causing elastic sealing disc to distort
Inventor: BAUMGART HANS
IPC: F16K47/02
Filed: 1977-03-11
Abstract: The silent-working liquid flow control valve particularly for a radiator or other heater, has a stationary seat, and a plug sliding axially. At the free end of the plug is a disc or elastic material, working against the seat, and mounted on a rigid support. The face (33) of the support (26), against which the disc (35) bears, is convex. In the unloaded state the disc is not complementary to the support face, which causes it to distort. The external dia. of the convex surface can be greater than that of the sealing surface (15) of the seat (14), and the surface can run in a smooth curve, being of part-spherical shape. The disc can be held against it solely by a clamping ring (34) fitting over the edge.

Title: Stress limiting arrangement for IC engine poppet valve rotators - is raised step on rotator carrier preventing over-compression of return spring
Inventor: MAY ARNOLD DIPL ING DR ING
IPC: F01L1/32
Filed: 1977-08-03
Abstract: The stress limiting arrangement for poppet valve rotators applies to rotators using balls/rollers travelling along peripheral grooves with sloping bottoms (4) in a ring (3) under the spring carrier (1), with return springs (5) to push them to the shallow end when the valve spring is uncompressed. To prevent the return spring being overstressed by being compressed coil-to-coil the ring (3) is made with the step (7) in the top surface so that when the rotator operates the spring carrier rolls the ball only part way down the slope. Alternatively a "soft" spring material capable of withstanding coil-to-coil compression can be used.

Title: Permanent magnet motor arrangement - uses multiple permanent magnets mounted with opposite poles facing one another on stator and rotor, with superconducting screening plates
Inventor: PRANGE EMIL
IPC: H02K53/00
Filed: 1977-11-23
Abstract: A magnetic motor uses permanent magnets mounted on a stator and on a rotor. Unlike poles are arranged immediately adjacent as the rotor moves around inside the stator, and metal plates arranged in their own cooking unit are filled with a cryogenic coolant to make the plates superconducting and thus to screen-off the magnetic fields of the permanent magnets. The energy of the force fields is used as the driving force behind the motor. The arrangement of the permanent magnets and screening plates is designed to convert the attraction forces between the magnets into a unidirectional rotation of the rotor to drive other machines, appliances etc.

Abstract: The heat conveying medium pref. water, is only circulated when the temp. in the collector exceeds that in the heat energy storage tank, and when the temp. of the medium is lower than its temp. of vaporization less a safety factor, (in the case of water, is 80 degrees C). A high degree of efficiency is achieved in a solar heating installation for which the mfg., installation and maintenance costs are low, since the system is not pressurised.

Title: Camera exposure control circuitry - uses digital counting technique to control exposure value stored in ROM with actual shutter opening
Inventor: TOYODA KENJI
IPC: G03B7/091
Filed: 1977-12-23
Abstract: A photocell output is converted to a logarithmic analogue signal and then an Analogue/Digital converter feeds the digital form into a ROM. A variable resistance is used to feed information about the aperture setting through an analogue converter (5) and A/D converter into the ROM. Film speed information likewise is fed from a variable resistor, analogue converter, A/D converter into the ROM. An electronic switch controls information input to the ROM and a decoder and display provide viewfinder information. An impulse generator feeds pulses to the shutter control circuits. Light values are given a 'pulse number value' and the shutter exposure time is measured in pulses. When the shutter release is operated pulses from the ROM are counted against shutter pulses, until these are equal when the chutter is closed.

Filed: 1977-12-24
Abstract: Positive etch-resistant masks are made using a radiation-sensitive layer of un-crosslinked (meth)acrylate polymers with side-chains of varied length, pref. copolymers from >=2 monomers. Before irradiation, little or no pre-bake is given in dry inert gas atmos. wt. just above the Tg temp To dry and stabilise the layer and improve its adhesion, without causing crosslinking. Used in UV, X-ray or electron beam lithography in semi-conductor technology, for making printed circuits, etc. with high resolution. The coatings have high sensitivity to radiation and good application properties to a variety of substrates e.g. coating, adhesion, developing, etch-resistance and removal after the masking process.

Title: Centrifugal power drive unit for universal use - has rollers with jet nozzles on rotary bearing ring rotating at twice its speed
Inventor: PIEL KURT DIPL ING
IPC: F03G3/00
Filed: 1978-01-09
Abstract: The centrifugal power drive unit has rotary rockers weighted at the ends and with jet nozzles and mounted in a bearing ring rotating in the same direction their speed of rotation being double that of the ring. The effect is that during a revolution of the ring round a central shaft the centre of gravity of each weighted rocker end varies in position from a max to a min radius and back again, the angular velocity of the weighted ends about the central axis likewise decreasing and increasing. The nozzles merely function when at the max distance from the central axis and in the desired main thrust direction of the complete power unit. The peripheral speed of the rocker ends about the central axis and the discharge speed of the propellant gases from the nozzles can be brought to a sufficiently small proportion to keep the trail of gas behind the unit short.

Title: Filter press compressible plate - has relatively thick perimeter which consists of elastically compressible chamber
Inventor: HERMANN MANFRED P DR
IPC: B01D25/21
Filed: 1978-02-16
Abstract: The perimeter of the plate is thicker than its middle zone, and is formed by walls (a) which are monolithic with the plate. The two walls (a) on each plate are pref. connected together on the perimeter of the plate by flexible bellows, so the chamber collapses when axial pressure is applied to a row of the plates. The compressible chamber is filled with a reaction agent, pref. a rubber elastomer; compression springs; or a hydraulic- or pneumatic-medium. The reaction agent may also consist of rows of sliding wedges moving outwards when a row of filter plates is compressed axially. At the end of a filtering cycle, a row of plates can be compressed to drive liq. through the filter cake, so the amt. of liq. in the latter is reduced.
