Patent DE-3026797-A1 (DE)
Title: Collectorless D.C. motor - has rotor magnet poles with small pole gaps and varied air gap between poles and stator
Inventor: WAGNER MARTIN
IPC: H02K29/08
Filed: 1980-07-15
Abstract: The external rotor motor (1) has a two pole rotor (2) formed as a continuous magnetic ring and a double 'T' yoke stator (5) with upper and lower pole (6a,7a). Grooves (8a,9a) between the stator poles carry the two windings (10,11) which run starting from the positive pole (12) and have their ends connected to the transistor circuitry (16,17). A digital switching Hall I.C. (13) fed from the positive pole via a series resistor (18) is used as a rotational position detector, the output controlling the transistor (16) directly, and the second transistor (17) via an inverter stage. The rotor magnet poles exhibit a trapezoidal, sinusoidal or rectangular magnetisation with small pole groups (3,4) between the poles (6,7), and the air gap - seen in the direction of rotation - in the area between slot openings (8,9) starts off with its greatest depth at the slot opening (9). It then becomes smaller over an angle of some 30 to 70 degrees electrical, and runs to the next pole (8) with a constant gap. This design exhibits a current characteristic with practically no null value.

The tool is provided with a sealed heat pipe (2) which extends from the cutting edge area. The heat pipe is partly filled with a substance which, at the operating temperature, changes from the solid and/or liquid state into the vapour state, to transfer heat to a cooling zone (5) above the cutting edge. This zone may be outside the body of the tool and may have a heat sink with cooling fins.
Patent DE-3029932-A1 (DE)
Title: Processing of analogue measurement signals - using digital converter connected sequentially to measurement and two reference voltages
Inventor: MONGER RAYMOND F DIPL ING
IPC: H03M1/00
Filed: 1980-08-07
Abstract: An electronic system for processing signals is applicable to many measurement monitoring and control processes, typically temp. sensors and digital voltmeters. An analogue voltage to digital signal converter can be connected to the measurement voltage (Vin) and reference voltages (Vo,Vref) in a defined sequence. The resulting sequential digital signal is processed to derive the measurement voltage. Digital pulses are counted during a set period in which the converter is connected to each voltage source in turn. The resulting numerial values are stored at least temporarily and then processed in combination with a value derived directly from one reference voltage (Vref). One reference voltage may be zero. The measurement voltage value is calculated from values N1,N2,N3 and N4 corresp. to the measurement voltage (Vin), the first and second reference voltages (Vref. Vo) and the fixed reference value. The derived value is (N1-N3) divided by (N2-N3) with the quotient multiplied by N4.

Patent DE-3100031-A1 (DE)
Title: Desorption device for the absorption cold and/or hot pump process
Inventor: MALEWSKI WERNER DR ING
IPC: F25B33/00
Filed: 1981-01-02
Abstract: The invention relates to a device for introducing heat into a cyclic absorption process with simultaneous rectification of mixed vapours. The heat injection has to take place throughout the desorption process, including the subsequent rectification, it being possible to utilise the substantial temperature differences between head (lowest temperature) and bottom (highest temperature) of the column. The device according to the invention, which is shown by way of example in the drawing, enables the introduction of heat along the column during the rectification process, the solution to be rectified being distributed as a falling film on the inside walls of vertical pipes arranged in a bundle and flowing in countercurrent to the rising mixed vapour. On the outside of the tubes, that is to say in the enclosing space, the heating agent flows vertically upwards so that it is able to supply heat to the falling solution through the pipe wall up to the coldest point in the column head. When heating agents flowing upwards in the enclosing space of the column section cool down on giving off heat, which is the case for flue gases from directly heated desorbers, the trend of the temperature variation corresponds to that in the interior space of the tube. Lower waste-gas temperatures can consequently be achieved, which improves the firing efficiency.

Patent DE-3106157-A1 (DE)
Title: Method for systematic testing of functional units of a centrally controlled system, in particular a telephone switching system, which have test points which can be monitored
Inventor: LINDEINER HANS-D VON DIPL ING
IPC: H04Q1/24
Filed: 1981-02-19
Abstract: For computer-aided testing by means of a test device (PE) connected to the system by means of a data channel (DK), the test points are combined to form test complexes. The information required to define the respective test points (e.g. switching points) is stored in the individual spaces of an individually allocated memory section (SA) of a memory device (S). The test programs use these values as parameters. Only the respective memory section is addressed on the basis of corresponding commands via the existing control unit. The contents of the individual memory sections can be read out by means of a continuous addressing incremented through respective increase by the value (1). Thanks to the storage, carried out according to the invention, of all the specific data of the existing test points, such as those representing relay, circuit and switching point coordinates, there is no need for complex calculation of the individual addresses which are to be allocated. A change in the system structure, of the type that can occur, for example, due to modified relay addresses, results merely in a correction of the parameters, while the test programs can be retained unchanged in the test device. <IMAGE>

Title: Crossing of a first roadway with lane-making side webs with another roadway
Inventor: TITZ WALTER
IPC: E01B25/12
Filed: 1981-05-22
Abstract: The invention relates to a crossing of a first roadway provided with lane-making side webs with another roadway which has at least one horizontally movable servo-drivable section of one side web. The web section is pivotable between an operating position lying in alignment with the associated side web and a waiting position aligned approximately parallel to the edge of the other roadway. To achieve short change-over times in spite of a large and heavy design of the movable web section, the two end positions of the web section are assigned in the region of their free end in each case at least one damping buffer and an automatically falling-in ratchet latch effective in the pivoting direction, the ratchets of which can be lifted by means of a servomotor. A positive priority control of the operating cylinders of the web section and of the lifting servos ensures an operationally safe and rapid performace of the change-over, there being connected in front in the region of the end positions delay sections which, in interaction with the damping buffers, ensure bump-free running into the end positions and a safe falling-in of the ratchets.

Title: Circuit arrangement for limiting switching-on currents
Inventor: KUPKA DETLEV ING GRAD
IPC: H02H9/00
Filed: 1981-06-09
Abstract: The circuit arrangement for limiting switching-on currents, which uses a current-limiting resistor during switching on, is intended to prevent a larger current surge being produced when the current-limiting resistor is short-circuited than during switching on. The bridging of the current-limiting resistor is initiated by means of a zero-voltage switch after a defined time delay, and is not carried out until the instantaneous value of the sinusoidal mains power supply voltage has reached the value of the opposing voltage, for example a capacitor voltage. <IMAGE>
Patent DE-3126536-A1 (DE)
Title: Device for driving in fastening means
Inventor: WILLENBROCK HANS DIPL ING
IPC: B25C5/16
Filed: 1981-07-04
Abstract: Devices having replaceable magazines have been developed for processing staples and pin-like fastening means, such as nails. It has become evident, however, that the different behaviours of fastening means causes difficulties as they are driven in. The fastening means are here pressed beneath the impact cutter of the driving-in device by a slide under spring tension and are individually cut off. An attempt has been made with stopping slopes, for example, to prevent the tipping of the staples out of the driving-in direction during the driving-in process. Pin-like fastening means, for example nails, are cut off in the region of the stopping slopes for the staples. The stopping slopes cause the cutting-off edges for nails and pins to be offset, which means that it is frequently no longer possible to cut off only one item faultlessly, i.e. the front nail. This causes problems. To remedy these disadvantages, separate guide grooves are provided for the staples on the one hand and for pin-like fastenings on the other hand.

Title: Drum bearing arrangement, in particular for drum washing machines and centrifuges
Inventor: BARTH ERICH
IPC: D06F37/00
Filed: 1981-09-02
Abstract: The invention relates to a drum bearing arrangement for drum washing machines and centrifuges which are subjected to different mechanical loads and are equipped with rolling bearings. The invention is intended to achieve the object of achieving an optimum bearing seat, appropriate to the mechanical loads and materials used, with in each case one rolling bearing. According to the invention, the object is achieved by the fact that the bearing seats both in the hub and on the shaft represent hard press fits only in the edge zones and, in between, have reliefs, giving two annular supporting surfaces, the one entering first into the press fit during assembly being wider than the second annular supporting surface, and that the width of the reliefs depends on the material of the shaft or hub and the width of the rolling bearing, such that, with the chosen fit, approximately equal elastic surface pretension and surface compression exists due to low compression and smoothing in the press-fit region. Possible areas of application are for drum bearing arrangements for drum washing machines and centrifuges and bearing arrangements in which the material of the bearing seat is considerably softer than that of the bearing. <IMAGE>
