Patent DE-3144174-A1 (DE)
Title: Device for field-oriented operation of a rotating field machine
Inventor: NAKANO TAKAYOSHI DIPL ING
IPC: H02P21/14
Filed: 1981-11-06
Abstract: A control device uses a desired value (e.g. derived from the control deviation for the flow  phi ) for the component i@1 of the stator current vector parallel to the flow and a desired value (e.g. derived from the rotation speed deviation or the desired torque) for the current component i@2 at right angles thereto to form the spatially fixed components of the desired stator current by means of the flow angle (cos phi , sine phi ) and converts said components into control variables (i@, i@, i@) by means of which a final control element (current regulator 16a, 16b, 16c, converter 17) controls the stator currents for the rotating field machine (19). The flow angle  phi is taken from a flow computer (20) which provides modelled values for magnitude and direction of the flow from the stator current and the rotor angle  lambda  (rotor angle detection device 21) and from a set parameter value for the rotor time constant T<L>. The set rotor parameter value is adjusted as a function of a rotor temperature value. To this end, the stator temperature can be measured, an estimated temperature value for the rotor temperature can be formed in an algebraic function generator, and this parameter value can be determined in accordance with a rotor time constant/rotor temperature characteristic. <IMAGE>

Title: Control method and device for a drilling process
Inventor: ZILIKOV VALENTIN V
IPC: B23Q15/12
Filed: 1982-02-26
Abstract: In the first cycle of the two-stage drilling test, a drilling rate is determined according to preset values of controlled parameters and approximate quantities of factors of the adaptive model which are to be supplemented, which drilling rate is compared with a value, measured in the same cycle, of the given rate, and, after the results of the comparison, corrected values of the corresponding factor to be supplemented of the adaptive model are formed, with regard to which the values coming closest to the optimum values of the control signals are determined, which values appear as setting values for acting on a drill bit in the following cycle of the drilling test. During every following cycle, the supplemented factors of the preceding cycle are used in determining the control signals. If the measured drilling rate and the drilling rate to be determined coincide in two successive cycles, a control signal formed during these cycles appears as a signal which is used in the actual drilling operation. <IMAGE>

Patent DE-3212699-A1 (DE)
Title: Device for fixing the heating-pipe coils of a floor-heating system
Inventor: WISMER KLAUS
IPC: F24D3/14
Filed: 1982-04-05
Abstract: The heating-pipe coil to be embedded in the composition floor is to be laid exactly corresponding to the precalculated plan over the insulating layer which mostly essentially consists of polystyrene panels. For this provisional fixing of the heating-pipe coil, use is made of a provisional frame, in particular a structural steel grid. After setting of the composition floor, however, the structural steel grid is without function, and represents a relatively great material loss. According to the invention, instead of such a structural steel mat, there is provided a board (5) made of corrugated board or ribbed board, on which the heating-pipe coil (4) is fixed by means of fastening elements (6) provided with barbs (7). The heating-pipe coil (4) can thus be laid "steplessly" according to plan. The multi-layer board serves subsequently to improve the heat and sound insulation. <IMAGE>

Title: Head amplifier for a video recorder
Inventor: KLUTH HANS-JUERGEN ING GRAD
IPC: G11B5/02
Filed: 1982-05-27
Abstract: In a head amplifier for a video recorder, the head inductance (5) is tuned, during recording, to a series resonance frequency in the upper range of the frequency spectrum of the recorded carrier by means of a capacitor (4) located in the signal path. The series resonance cancels the record current in the upper frequency range. The capacitance decreases the record current in the lower frequency range. This makes it possible to achieve a constant record current over the entire frequency spectrum, and thus a better signal/noise ratio. <IMAGE>

Title: Mainsheet guide for sailing boats
Inventor: EMMENEGGER BERTHOLD
IPC: B63H9/10
Filed: 1982-07-05
Abstract: The runner (traveller) attached to a guide rail can be pulled or pushed into any position without belaying the trimming lines, in which case it maintains this position in light winds. Undesirable running-away when going about to leeward is prevented. In stronger winds, the runner can be belayed in one of the clamps by means of one of the trimming lines. Here, the brake does not have a disturbing effect. At the foot block of the mainsheet, which foot block is arranged at the runner, the runner cannot be unintentionally pulled to windward when the mainsail is tightly set. The brake can be disengaged so that the runner is freely movable on the guide rail. The runner is locked by a brake (6, 7) under spring pressure. The brake is released by pulling or pushing on the slide (2), as a result of which the brake (6, 7) is released via the lever (4). The brake is disengaged or engaged via the eccentric shaft (5), which lifts or lowers the lever (4) and the brake (6, 7) by means of the lever (11).   <IMAGE>

Title: Infinitely adjustable positive orbiform-cam stop-motion linkage for producing sequences of motion with one or more dwells of the output shaft and partially reversed movements
Inventor: KLING WILHELM J K
IPC: F16H27/02
Filed: 1982-07-14
Abstract: Infinitely adjustable positive orbiform-cam stop-motion linkage for producing sequences of motion with one or more fixed dwells of the output shaft and partially reversed movements. For the production of partially reversed movements (step-back movement), the advantage of the invention is to be seen in the fact that the actuating angle for the forward and reverse movement is infinitely adjustable and that, by virtue of the individual displacement of the rocker shaft in the respective actuating systems, the ratio of the forward and reverse movement is also infinitely adjustable. Such movements are required to meet various technological conditions of the workpiece to be processed by the machine (flax-breaking machine, interruption to cutting in turning) and could hitherto only be achieved at high cost. The infinitely variable mutual offsetting and fixing of the cam discs on the input shaft make it possible to adjust the ratio of actuating time to dwell time and to adapt the actuating time and the actuating angle to the particular requirements, the actuating angle being altered in infinitely variable fashion by means of the individual or common displacement of the rocker shafts while the actuating time remains approximately the same.

Filed: 1982-10-13
Abstract: The dry toilet consists of an airtight container (1) with a decomposition container (4) arranged therein, to which excretion substances can be fed through a closable opening (3). When the lid (5) is opened, a ventilator (16) is switched to increased output via an end switch (39) and, at the same time, the decomposition chamber is closed by a circulating air-flap (17). The excretion substances and portions of additives (7) situated in a storage container (6) pass between two rollers (18, 19) which are rotated in opposite directions via a chain drive (27) by the closing of the lid (5). By this means, the different substances are mixed and conveyed into the decomposition container (4). With the closing of the lid (5), the circulating-air flap (17) is opened at the same time and air is blown into the humus container (14) and the decomposition container (4). If there is too much liquid in the humus container (14), scanning electrodes (52) switch on a heater (28) which is situated at the base below the humus container (14). <IMAGE>

Title: LR stereo disc
Inventor: RIMOLDI LUIGI
IPC: G03B35/04
Filed: 1982-11-06
Abstract: The invention relates to a stereo disc for producing pairs of three-dimensional images using a single camera. The LR stereo disc comprises two parts: the disc with a straight guide rail and the three bulges, and the guide shoe, which is screwed onto the bottom of the camera. Only when the two desired bulges are used is the camera made able to swivel on this straight guide rail. The camera is also made able to swivel if it is fitted on the guide shoe and, using the diminishing guide screw, is guided by being set to the straight guide rail with bulges locked. Trouble-free, high-quality stereo photographing of objects, no matter from what range, between 5 cm and 3 m, is now made possible for the first time either by using this novel guide rail or by means of the diminishing guide screw with bulges locked. This takes place without using special stereo cameras or optical accessories, in a simple and inexpensive way.

Title: Circuit arrangement for generating a digital binary data signal and an associated clock signal from a CMI-coded signal, the clock frequency of which is above 30 MHz
Inventor: BECKER DIETER ING GRAD
IPC: H04L25/49
Filed: 1982-12-30
Abstract: It is known that because of the spatial distance between data source and multiplexer or demultiplexer and terminals, a special line transmission must be provided in future broadband transmission networks for digital television, audio broadcasting, video telephony and other data signals. In CMI-coded transmission of the information items, an additional transmission of the clock signal can be omitted since this is generated at the receiving end by clock generator synchronised by the CMI-coded signal. The circuit arrangement according to the invention (Figure 1) generates from a CMI-coded signal CMI a corresponding binary data signal D and essentially consists of a first delay section 3, an EXOR gate 4 and a D-type flip  flop 9. The clock signal T belonging to the data signal D is obtained directly from the CMI-coded signal CMI by means of the first delay section 3, a first and a second NOR gate 5 and 6, a second delay section 7 and an inverter 8. The first delay section 3 has a delay time of half a bit period and the second delay section 7 has a delay time of a whole bit period. If the circuit arrangement is constructed in ECL technology, signals of up to more than 70 MHz can now be processed because only the relatively fast switching elements of a circuit family are used.

Patent DE-3310205-A1 (DE)
Inventor: SCHLUETER GERT
IPC: C12Q1/24
Filed: 1983-03-21
Abstract: A device for the uptake, transportation and recovery of cell material present in body fluids, cell-fixing liquids, and mixtures of body fluids and cell-fixing liquids, and also for the transfer of the recovered cell materials to microscope slides. The device comprises a vessel (1) with an inlet (2) and an outlet (3); a removable fiber element (5) is arranged, flush with the wall, in the outlet (3), and comprises fibers which are insoluble in body fluids and cell-fixing liquids and which are arranged lengthwise in the direction of the long axis of the vessel (1) with the formation of through capillaries, such that the capillaries have a smaller diameter than the diameter of the cells. The vessel (1) can be liquid-tightly and gas-tightly closed. Preferably, the fibers of the fiber element (5) are crimped and/or texturized fibers and/or hollow fibers. In contrast to conventional devices and methods for the recovery of cells from cell-fixing liquids, in which the cells must be caused to sediment or settle and a long time is required, the separation of cells and cell-fixing liquids takes place in a very short time with the device according to this invention. Apart from this, the recovered cells can be directly transferred to microscope slides. As fibers for the fiber element (5) there can be used, for example, stuffer box-crimped polypropylene fibers or cellulose-2,5-acetate fibers. Cell-fixing liquids are, e.g., methanol, ethanol or isopropanol. Body fluids are, e.g., urine, cerebrospinal fluid, pleural effusions, or ascites.

Title: Multi-flap valve for hot gases
Inventor: MUELLER RUDOLF
IPC: F23L13/08
Filed: 1983-04-15
Abstract: The invention relates to a multi-flap valve for hot gases, the valve flaps of which are rotatable by drive shafts which are mounted on a common valve housing, each have an actuating lever outside the valve housing and are actuated by a common driving linkage which connects the actuating levers to one another. In order to ensure that the valve always closes with a satisfactory seal, even in the hot condition, the actuating levers 10, 11, 12 and 13 are designed as flectural bars, the flexibility of which is designed to correspond to the difference in thermal expansion occurring in operation between the valve housing 1 and the driving linkage 14a to 14d. In this way, the actuating levers 10, 11, 12 and 13 are capable of bending in order to compensate the differences in thermal expansion which occur and, at the same time, of actuating the drive shafts of the flaps with a torque which guarantees the satisfactory closing of the flaps at all times (Fig. 2). <IMAGE>
