Title: Laminated capacitor with metal-free strips dividing metal layers - into areas and side metallisation allowing continuous capacity adjustment
IPC: H01G4/30
Filed: 1976-10-21
Abstract: Laminated capacitor consists of a stack of alternating layers of dielectric material and metal divided by metal-free strips in a plane adjacent to the metal layers, which extend to opposite sides of the stack to metal coatings providing contacts, as in DT 2509669. Improvement is that the metal-free strips divide the metal layers into (un)equal areas.

Title: Open=end spinning turbine - with permanent ring magnets which automatically reseat exactly after rotor cleaning
Inventor: QUANDT GERHARD DR ING
IPC: D01H4/12
Filed: 1976-11-27
Abstract: Turbine for an open-end spinning machine has a stub radially mounted in a sliding bearing bush held in a floating bearing in the housing, while a permanent ring magnet holds the rotor in the correct position in operation. The rotor and the floating bearing section, in the required rotor position, have two concentric rings within each other in >=1 plane at right angles to the axis. Of these rings, one is the axial magnetised permanent ring magnet while the other ring is either of soft iron or also a permanent ring magnet. They provide a holding action if the rotor slides out of the required operating position. The stator and rotor form part of an emergency bearing which also hold the displaced turbine and prevent any further sliding movement. Design ensures that the floating bearings always return to their exact location after cleaning, even after the rotor has been swung out of action repeatedly.

Title: Testing and regulating gas producing rubbish dumps - using sonde gauges to prevent extraction rate drawing in air
Inventor: JOHNSON ROBERT D
IPC: C12M1/107
Filed: 1977-04-30
Abstract: A method of drawing gas from a rubbish dump on which there is a anaerobic fermentation, without introducing air in a quantity which would destroy its capacity to produce methane is carried out in a series of steps. Test shafts are bored, and gas is drawn off whilst maintaining a pressure which is low enough for the gas in the dump to flow into the boreholes being tested. At the time over a region near the test holes, other holes varying in depth and penetrating through the top covering layer into zones where fermentation is going on, are sunk for tubes fitted with pressure gauges. The magnitude of the first pressure at which the gasis extracted is then controlled continuously relatively to the pressure in the zones monitored by the sondes, so as to ensure that pressure does not fall below that of the atmosphere and air be drawn into the dump. On a basis of the tests carried out, a maximum extraction rate is decided. The tests are carried out on destroying the active bacteria by admitting oxygen.

Title: Parallel additional arc welding current source - with voltage below arc voltage inserted for drop short circuit duration
Inventor: RIPKA KARL WOLFGANG DIPL ING D
IPC: B23K9/10
Filed: 1977-06-16
Abstract: Current source for arc welding sets has an additional rectifier, fed by a polyphase a.c., in parallel to the conventional d.c. welding current source. The additional rectifier operates in a semiconductor device bridge circuit and can be electronically controlled or cut ON and OFF. Its voltage is lower than the working arc voltage and supplies the required booster current only every time a drop of molten electrode metal causes a short-circuit and zero arc voltage. The duty cycle of the additional rectifier can now be readily interrupted so that the electrode cannot become stuck to the workpiece. The additional rectifier need not be dimensioned for continuous duty but can be smaller, i.e. short-time rating.

Title: High speed photographic paper processor - uses rollers and wiper blades to remove excess soln. and prevent carry-over from one bath to another
Inventor: GANSER FRIEDRICH
IPC: G03D3/13
Filed: 1977-06-30
Abstract: Appts. removes surplus soln. and reduces carry-over from one bath to another in a processing machine for roll photographic paper. The appts. is effective in high transport speed processors. Between one bath (4) in its tank (1) and the second (3) is a dividing wall (2) with an aperture (10) through which the paper passes. The paper (6) is carried through the processing bath (4) on rollers (5) and then towards the aperture (10) on a series of rollers (7, 12, 13, 9) designed to throw off surplus chemical from the processing bath. This is aided by wiper blades (14a, 14b, 15) between the lower rollers (7, 12) and on another roller (13) face.

Title: Transmission system with large dimension waveguide - has cross=section symmetrical relative to right angled planes
Inventor: SPINNER GEORG DIPL ING DR
IPC: H01P1/16
Filed: 1977-08-17
Abstract: A transmission system (10) is used which incorporates a wave guide of large dimensions. The size of the wave guide will allow several wave forms. However will only transmit the dominant mode. The design tolerances will be reduced and a wide band compensation of polarisation rotation of the two transmission planes will be made possible. The cross-section of the wave guide is symmetrical with respect to two planes at right angles to each other. The line of intersection of the two planes respond to the axis of the wave guide. The wave guide can be formed by a circular tube with four indentations each displaced by a right angle. It can also be a tube with a square cross-section. It is made from a soft metal such as aluminium.

Title: Drawing die for continuous welded tube mfr. - using a polygonal surface on the conical inlet of the die
Inventor: OPPERMANN W F
IPC: B21C3/02
Filed: 1977-08-27
Abstract: The appts. includes both tube welding and drawing plant, using a die with a polygonal surface forming its conical inlet. the peaks of each surface segment are pref. located alternately at the inlet and outlet ends of the die. The number (A) of corners in the polygon pref. complies with the formula A = D Pi k; where D is the outside Dia. of the tube blank and k is a factor; grooves are pref. ground in the inlet cone, esp. spiral grooves. When drawing a tube blank with a redn. of over 20% in tube dia. the tube can weld in the die bore, thus impairing the surface quality of the tube. The appts. avoids this problem.
