Title: Demagnetising circuit for colour TV receivers tube - has series LC circuit shunted by semiconductor switch connected via resistor network, producing grid voltages for triple beam tube
Inventor: GOSEBERG WALTER DIPL ING
IPC: H04N9/29
Filed: 1978-08-14
Abstract: The demagnetising circuit has the demagnetising coil (13) in series with a capacitor (12). This series combination is shunted by a bidirectional controlled semiconductor switch (14) and is connected at one end (capacitor end) via a resistor network (7-11) to a tapping on the winding (6) of the line transformer supplying the rectifier cascade (3) that generates the high voltage for the tube (5).

Title: Respirable gas supply for aircraft cabins - by adsorptive removal of nitrogen from compressed air
Inventor: BENKMANN CHRISTIAN DIPL ING
IPC: B01D53/04
Filed: 1978-08-25
Abstract: Respirable gas for the cabins of aircraft with an oxygen concentration depending on the flight altitude is produced from compressed air by a controlled adsorptive removal of nitrogen. Alternating cycles change from an adsorption phase where the nitrogen share at the outlet rises, to a counterflow desorption phase. The oxygen concn. is adjusted by changing the flow rate through the adsorber and/or the ratio of adsorption to desorption pressure. The oxygen concentration which must be varied to suit different flight altitudes and cabin pressures can thus be controlled with a minimum of apparatus and instrumentation and in the most flexible way.

Title: Fast curing unsaturated polyester foam prepn. - using bi:carbonate and orthophosphoric acid to generate carbon di:oxide blowing agent at controlled rate
Inventor: FILIP STANISLAW FRANZ
IPC: C08J9/00
Filed: 1978-09-06
Abstract: Prepn. of a foam from an unsatd. fast curing polyester resin of viscosity 1800-3000 cps., vinyl comonomer, finely divided bicarbonate and nucleating agent, and peroxide catalyst initiating crosslinking of the resin in 2.5-6 mins., comprises mixing the components and incorporating a 30-40% aq. inorganic orthophosphoric acid exhibiting progressively decreasing level of activity on reacting with the bicarbonate to form CO2. The acid forms salts acting as surfactant to help to sustain the foam before gelling occurs. Mixing of the components takes place at an accelerated rate to blend the acid throughout the compsn. to liberate CO2 before crosslinking has gelled the resin.

Title: IC engine ferrous piston ring flank hardening - is carried out in two stages separated by tool cutting operation for distortion correction
Inventor: HUMMEL HAGEN
IPC: C21D9/00
Filed: 1978-12-23
Abstract: Pistons consist of several parts and are made of ferrous material hardened by local heat treatment, pref. by an electron beam method, along the flanks of the annular piston ring grooves. The flanks are subdivided into a radially inner part and an outer (much smaller) part which are heat-treated separately. Any distortion caused by the hardening of the radially inner part of the flanks can now be rectified by a metal-cutting tool. The subsequent hardening of the narrow (under 1mm.) outer flank part does not cause any distortion. This saves the expensive copy grinding which is needed if the flanks are hardened in one operation.

Title: Deformable multiple path contact element for bridging conductors - is made of elastic material coated with thin conducting film
Inventor: FUCHS HELMUT
IPC: H01R31/00
Filed: 1979-04-12
Abstract: An elastically deformable bridging piece can be used to provide the electrical contact between a circuit board and a liq. crystal display unit. The basis of the deformable contact is an elastomer or similar material. At the same spacing as the conductors (15, 16) on the parts (17, 18) to be connected together the elastic material is covered with a thin film of conducting material (13). By bringing the two parts (17, 18) together under some form of constraint a positive contact pressure is exerted on both conductors (15, 16). The elastomer may be formed with two different cross-sections. The larger (11) is covered with the conducting film (13), and forms the connector (12). The smaller (14) is uncoated and serves as a mechanical joining strip.

Title: Fuse and detonator with pressure resistant watertight joint - made by lubricated sleeve between fuse and capsule
Inventor: SOBBE FRIEDRICH WILHELM DIPL K
IPC: F42D1/04
Filed: 1980-03-15
Abstract: The parent patent describes a detonator with fuse for military purposes, esp. for detonation in great depths of water or high-pressure environments. The connection between the fuse and the capsule of the detonator is made by introducing a sleeve between these two; the sleeve has markings to enable the correct depth of insertion of the fuse to be achieved. In the patent of addition, this sleeve is lubricated with a hydrophobic lubricant to assist its insertion into the capsule. The lubricant may be applied to the inner and outer faces of the sleeve. Pref. lubricants are: a silicon wax; a mixt. of silicone oil and liquid paraffin, esp. comprising 50-75% of silicone oil. This arrangement enables slight divergences in the gap between the thin sleeve and the fuse and/or capsule to be made up in a satisfactory, watertight manner.
