Title: Variable frequency synchronous generator - has alternating excitation supply which is provided by an exciter with required frequency input
Inventor: OPITZ GERHARD
IPC: H02P9/42
Filed: 1974-10-22
Abstract: Generator and exciter are driven by a common prime mover and typically run at the same constant speed and thus have the same number of poles. Each machine is constructed as a three phase machine with three phase windings on both rotor and stator. The exciter stator is fed with a supply having the frequency required from the generator. The field revolves in the same direction as the rotor and thus induces in the latter currents of a frequency given by the difference between shaft speed and magnetic field speed. Exciter and generator rotors are electrically coupled. The speed of the revolving magnetic field in the generator is thus the sum of shaft speed and field supply thereby generating in the stator winding a frequency equal to the exciter input frequency.

Title: Radiodiagnostic and cytological sampling appts. - to detect malignant tumours in the female breast
Inventor: KRAMANN BERNHARD DR
IPC: A61B17/34
Filed: 1975-01-15
Abstract: The breast is clamped against the film plate and filmed from one angle and a second angle at 90 deg. to the first one. The film plate contains the film holder which can be loaded and serviced even when the breast is clamped in position. A non-wrinkling roll of perforable Xray absorbent scanning grid film is arranged between the Xray tube focus and the breast. A holder attaching directly to the adapter rather than the extension tube of the Xray tube is coupled to a puncture needle over a hinged arm which permits multidirectional movement by the needle tip. The needle is on a sliding guide which permits it to be released into the centre of the radiographically detected tumour and remain there for removal of a tissue sample. A hole is provided in the upper clamping plate through which the extension tube or the puncture needle can pass.

Title: Wet processing, ie dyeing cotton piece goods - perforated guide plate eases progress of concertina folded fabric
Inventor: ECKRODT GUENTER
IPC: D06B3/28
Filed: 1975-01-23
Abstract: Textiles, esp. cotton piece goods are wet processed, and in partic., dyed in a stationary vessel partly filled with a liquor through which the goods are circulated by a reel picking up and feeding back the goods into the bath through a ring spray nozzle. The lye is circulated by a pressure pump drawing off from the vessel and delivering back along an arrangement of pipes to the spray nozzle. Inside the vessel, a perforated guide plate running in the direction of motion of the goods at a gradually increasing distance from the outer wall of the vessel, so as to remain near enough parallel to the inner wall, is provided. Part of the bath is thus able to flow through the guide plate which extends roughly to half the distance of the path travelled by the goods. The goods moved along the container wall are cushioned in practically a frictionless condition by the bath passing through the guide plate.

Title: Water draining double valve for cisterns - has large draining plug and smaller plug within large plug
Inventor: SIEGEL RUDOLF WENZEL JOSEF DR
IPC: E03D1/14
Filed: 1975-04-02
Abstract: The draining double valve releases different quantities of water to achieve saving of water eg in water closets and saving of hot water discarded on cooking. Different quantities of water are drained by using different handles and existing systems can be readily converted. After conversion a conventional flushing cistern has a valve tube for actuating the large bottom valve plug by a large handle on the valve tube for releasing full flow. The smaller quantity of water is released by a smaller handle which actuates, by a rod within the tube, the smaller valve plug within the large valve plug. The valve tube has holes at its mid length for water flow down to the smaller valve plug and hence the water valve after partial draining remains at the level of these holes.

Title: Rainfall catch basin - with relief sill in centre of bottom cone for water effluent free from solids
Inventor: POERSCH RUDOLF DIPL ING
IPC: B01D21/34
Filed: 1976-01-30
Abstract: The basin has a gently sloping conical bottom with a steeper central cone in the upward direction in the centre. An annular gutter at the base of the central cone removes grit and other solids. The central relief sill consists of a funnel on top and a vertical relief pipe though the apex of the central cone. This takes away the solid-free overflow water. The arrangement improves the sedimentation of sand and other solids and prevents the formation of solid deposits on the conical basin bottom.

Title: Hygienic rectal extractor for obtaining faecal samples - has sterilised tube with outer cleansing sleeve and sealing cap
Inventor: MALISIUS GUENTHER DIPL ING
IPC: A61B10/00
Filed: 1976-02-21
Abstract: The hygienic extractor for obtaining samples of solid or liquid stool (faecal matter) uses a sterilised, disposable tube which reduces the risk of contamination and flase results in the laboratory. A thin tube (1) is fitted with a sleeve of disposable material which can be flushed away in water (2). It is supplied with a cap (3) and pin in a sterile pack. The cap is removed and the end of the tube is inserted into faces. The tube is then withdrawn through the sleeve which wipes the tube clean. The end is then sealed and the device is taken to the test laboratory. The required amount of the specimen is then ejected by means of the piston (4) which is moved by insertion of the pin into the other end of the tube. A similar extractor with a rubber suction bulb is used for fluid samples.

Title: Lithographic printing plate not requiring wetting before inking - with ink-repelling surface layer accepting ink in image wise roughened zones
Inventor: ANDO ITSURO
IPC: G03G13/28
Filed: 1976-03-17
Abstract: Production of a lithographic printing plate, without the need for wetting with water by (a) first forming an electrostatic latent image on a lithographic original plate containing (i) an electrically conducting substrate (ii) a softenable layer applied on the substrate and capable of being softened when the electrostatic latent image is present and (iii) an ink repelling surface layer on the softenable layer, sufficiently thick and flexible for it to be able to be roughened when the softenable layer is roughened and on which the electrostatic latent image is formed and (b) subsequently roughening the ink-repelling surface layer in the pattern of the electrostatic latent image, when the softenable layer on which this image is present is roughened. Advantageously the successive roughening stages are brought about either by the use of heat or a solvent vapour on the ink-repelling surface layer carrying the electrostatic latent image. Permits a lithographic printing plate to be produced by a process easily carried out, and which can be used with both water- and oil-based inks.

Title: Single- or multistrand steel cable - with synthetic fibre sheath fused to strands
Inventor: LEHMANN KONRAD ROLAND
IPC: D07B1/16
