Patent DE-4314290-A1 (DE)
Title: Reluctance machine
Inventor: KUCHENBECKER MANFRED DR ING
IPC: H02P25/08
Filed: 1993-04-30
Abstract: The invention relates to a reluctance machine which can be operated both as a motor and as a generator, preferably for use as a starter/charging generator in motor vehicles. The machine requires only one winding for each phase, without any additional field winding (excitation winding). The coil arrangement for each case is such that the rear of the stator and the rotor inner ring in each case have to absorb only the magnetic flux of one tooth pair, so that the external diameter of the machine need not be significantly larger than the internal diameter of the rotor. The field current (excitation current) for generator operation is produced by a voltage being applied to each phase winding passing through the state of maximum reluctance between the switching points S2G and S1G, the polarity of which voltage, related to the winding, is inverted with respect to the charging voltage to be emitted. The field circuit is inhibited between the switching points S1G and S2G, and the machine emits a load current which is higher than the field current. <IMAGE>

Patent DE-4331023-A1 (DE)
Title: Milking machine
Inventor: MAIER PETER
IPC: A01J5/013
Filed: 1993-09-13
Abstract: In current milking apparatuses, animals are milked by the action of a vacuum, which interrupts the circulation of the blood and leads to mastitis. Furthermore, about 5% of the milk which could be extracted remains in the udder. The new milking machine is intended to prevent mastitis and extract the additional milk which can be extracted. The teat cup is composed of a sleeve (8) having a slot (c) into which the teat hose is inserted. The 3/4 double wall (b1) of the latter is divided into rings (d1, d2, d3, d4) and each ring is connected to its valve (L1, L2, L3, L4) by means of small tubes, with the valve aperture (g1, g2, g3, g4) on the reverse (f). The single-walled part of the teat hose merges into the milk pipe (b2) which is rounded off by means of the gaphriric nozzles (i). The nozzle is fastened to the fixer (h1) of the teat cup and to the lid (h2) of the milk collecting vessel (k) and is connected to the reverse pipe (L). The reverse, with a pressure increasing device (x) and two pressure relief devices (y1, y2) has the following arrangement: the distance between the pressure increasing device and the pressure relief devices is in each case the total of the diameters of two reverse pipes. Movement of the reverse and increasing and decreasing pressure results in a milking action in which the reverse movement causes the teat and the udder to be massaged. <IMAGE>

Patent DE-4338701-A1 (DE)
Inventor: PAWELZIK MANFRED
IPC: F16K11/074
Filed: 1993-11-12
Abstract: The invention relates to a mixing and shut-off valve with a handle (6) that can be moved with one degree of freedom and a valve housing (2) which has inlet and outlet openings, in which a valve-seat disc (4) is held in a manner fixed in terms of relative rotation and on which a valve-regulating disc (3) which can be rotated by means of the handle is mounted in a sealing manner, the valve-seat disc having inlet and outlet apertures which are connected to the inlet and outlet openings (23, 24, 25) and which, on the other hand, can be brought into overlap with a cut-out in the valve-regulating disc. To improve this valve, the proposal is that the outlet aperture should be arranged in the central area and the inlet apertures in the peripheral area, on a circumcircle, in the valve-seat disc and that the cut-out in the valve-regulating disc should overlap the outlet aperture and should be provided with two radial extensions (311, 312) for connection to the associated inlet apertures, the first extension being dimensioned in such a way that, with the mixing valve closed, it is situated, with the necessary spacing, between the two inlet apertures and, given a leftward rotation, moves into increasing overlap with the inlet aperture for the cold medium, while the second extension is positioned in such a way that it moves increasingly into overlap with the inlet aperture for the hot medium only after the maximum opening of the aperture for the cold medium has been reached and with further leftward rotation, this movement being such that there is at the same time a corresponding decrease in the overlap of the first extension with the inlet aperture for the cold medium. <IMAGE>
