Patent DE-3149766-A1 (DE)
Title: Two-pulse DC motor without a commutator
Inventor: MUELLER ROLF DR ING
IPC: H02K29/08
Filed: 1981-12-16
Abstract: The invention relates to a two-pulse DC motor without a commutator, having reluctance auxiliary torque. The rotor (16) has an approximately trapezoidal magnetisation with narrow gaps (17) between the poles. These gaps are set when no current is flowing through the motor for example such that they are located opposite the point (52) of the maximum air gap; the motor can start from this rotor position, i.e. it is in a start position. In order to ensure that this start position is reached reliably even in the case of dry friction, in a motor with salient poles (40), the air gap is severely stepped in the region of the grooves, to be precise such that a major increase in the magnetically effective air gap (19) up to a maximum (52) is produced both between the edges of the groove (44) and, adjacent thereto, in an order of magnitude of approximately the width of this groove. This results in a powerful driving reluctance torque of suitable form, which is synchronised very well to the gaps in the electromagnetic drive torque. <IMAGE>

Patent DE-3208153-A1 (DE)
Title: Impact fusion coating
Inventor: MUELLER FRIEDRICH
IPC: B26B21/60
Filed: 1982-03-06
Abstract: To produce coatings on tools in an especially efficient manner, which coatings substantially increase the cutting resistance and wear resistance, a method is proposed which, in contrast to the previously known methods, is suitable for carrying out with less expenditure of energy or in an automated manner. This is essentially achieved in that the tools with the sprayed-on coating are heated up to about 30 to 40 DEG C below the melting temperature of the coating and are inserted directly thereafter into a press tool in which the coating is pressed entirely or partly into the material of the tool and the tool is given its final shape.
Patent DE-3218374-A1 (DE)
Title: Device, containing a heat accumulation compensation circuit, for the electrical determination of the consumption of individual heat consumers
Inventor: VOELKER KARL
IPC: G05D23/19
Filed: 1982-05-15
Abstract: Devices for the electrical determination of consumption which have two or three sensors, in particular in heaters, are not reliable. A device is therefore proposed which is rendered safe against variation or the accumulation of heat by arranging to switch in, starting from a certain accumulation temperature, an additional circuit which simulates a temperature of the heat consumer that is higher than that determined by the sensor. In particular, however, it is also possible to use a thermostatic switch having two or more different switching stages or having a sliding switching point.
Patent DE-3219726-A1 (DE)
Inventor: BODEWIG PETER W
IPC: B23K9/09
Filed: 1982-05-26
Abstract: The invention relates to a process and an apparatus for metal arc welding with a consumable electrode. A pulsating current is supplied to the electrode from a constant current source. During the interpulse periods between pulses there flows a minimum current which is at least sufficient to maintain the arc. The switch from pulse current to interpulse current occurs as a function of the arc voltage, with switching to pulse current occurring if a minimum voltage is detected and to interpulse current occurring if a maximum voltage is detected. Compared with conventional metal arc welding with a consumable electrode, this method offers the advantage of a better welding quality.

Title: Magnetic-disk drive apparatus
Inventor: KOIZUMI SHIGEKI
IPC: G11B19/20
Filed: 1983-02-02
Abstract: The invention presents a magnetic-disk drive apparatus which is of a simple construction and is cheap to produce. A rotor (4) is connected to one end of the rotary shaft (3a) of a drive motor. On one part of the rotor (4) there is formed a spindle (5) for driving a magnetic disk (10), so that the number of constructional elements of the apparatus is small. In the case of one embodiment of the invention, two magnetic disks (9, 10) are turned by a single motor. At one end of the rotary shaft (3a) of the motor there is a first spindle (3) for turning a first disk (9). The other end of the rotary shaft (3a) of the motor is connected to a rotor (4), on which there is formed a second spindle (5) for turning a second disk (10). This arrangement allows a reduction in the number of motors for driving disks as well as a reduction in production costs. A simple and compact construction can be achieved, so that the device can be kept very narrow. <IMAGE>
Patent DE-3305344-A1 (DE)
Title: Round settling tank
Inventor: SCHNITZSPAN HANS-GUENTER
IPC: B01D21/00
Filed: 1983-02-17
Abstract: In a settling tank, designed as a round tank, in particular a trickling tank, with transverse through flow, a precondition for faultless functioning is that the waste water flows through the entire tank cross section essentially in a laminar and horizontal manner, without significant vertical or other additional flows, with correspondingly low through-flow velocities, essentially independent of the feed flow velocity. The object thus described is achieved according to the invention by arranging a horizontal dividing plate (8) centrally to the feed pipe, dividing the feed waste-water stream (14) into an upper and lower part-stream (15, 16), by the feed internals (4, 5) being composed of baffles (4) arranged at the feed-pipe opening and dividing the feed waste-water stream into part-streams and an at least two-shelled grid (5) extending from about the tank base to the maximum water level roughly enclosing the feed-pipe opening in a circular manner, the grid (5) being composed of roughly vertically running grid rods (10, 11, 12) (planks, metal sheet strips, tubes) arranged in an offset manner on a hatch, and by arranging an overflow channel (1), including about 1/3 of the tank circumference, opposite to the feed. <IMAGE>

Title: Filling level measuring device with a lever bearing a float
Inventor: RAU KARL
IPC: G01F23/76
Filed: 1983-03-02
Abstract: In a filling level measuring device with a float, the latter is constructed as a shallow, rectangular hollow body and both end faces of the float are provided in each case with a depression, which depressions connect the two end faces to one another and one of which extends beyond the centre plane parallel to the end faces. The deeper depression is constructed as a channel extending over the end-side surface. Moulded onto the side walls of said channel in the two end regions are in each case two opposite knob-type projections which form between them and the channel bottom a space lying in the centre plane for receiving the lever. Such a design of the float allows even the smallest residual quantities to be recorded.
Patent DE-3307547-A1 (DE)
Title: Device for controlling the speed of DC motors
Inventor: HOYER GERHARD
IPC: H02P7/29
Filed: 1983-03-03
Abstract: For special applications, for example for drives of surgical, dental and dental-technician drilling, grinding and milling tools, stabilised-speed and vibration-free motors are required for very different speeds and loads. The e.m.f. sampling method which can be used without access into the motor in order to obtain the control variable for speed stabilisation with the aid of a pulse-width modulator which is driven by a control voltage obtained from the control variable and a desired-value variable, is matched by means of the invention to these special requirements to the effect that the e.m.f. sampling phase is not repeated at the frequency of the pulse-width modulator (IM). To this end, the e.m.f. sampling phase is pulsed by a clock generator (TG) whose frequency differs from that of the pulse-width modulator. This is done with the aid of two switching elements (S1, S2) which, driven by the clock generator (TG), alternately interrupt the signal flow from the pulse-width modulator to a power switching transistor (LT) in the motor circuit and from the motor (M) to a comparator element (VG) in which the control voltage is obtained from the armature e.m.f. and a comparison voltage (Fig. 1). <IMAGE>

Title: Method and device for programming an electronic wrench
Inventor: MOHILO OSKAR ING GRAD
IPC: B25B23/147
Filed: 1983-05-25
Abstract: A method in combination with a device for programming an electronic wrench with regard to the maximum tightening torque of the screw when making a screwed connection is proposed, which method enables the limit data of a screw to be fed quickly and reliably as a program into the electronic wrench so that the latter is programmed for the tightening of the relevant screw. For this purpose, the screw is placed in a scanning device in which its characteristic values are automatically determined by appropriate measuring operations after the response of a release contact and are then fed into a computer, which from these values, in comparison with predeterminable standardised values, calculates the maximum size of the tightening torque of the screw, and this value can be programmed as a desired value in the electronic system of the wrench.

Title: Composite profile consisting of metallically connected metal tubes with interposed insulating material, for frames of wall elements, doors and windows, and a method for its production
IPC: E06B3/26
Filed: 1983-07-05
Abstract: The two steel tubes (6), having a rectangular cross-section, are connected to one another with the interposition of a layer consisting of insulating material (18) which can withstand fire and temperature, by means of bolts (7) which are welded to the mutually facing pipe walls and consist of steel which can be welded easily. The two steel tubes (6) with an interposed tool (8) which holds the bolts (7) by firmly clamping them are passed in steps through the welding station (3) on an inlet ring (1), and are passed away from there again on an outlet roller bed (2). The permanent connection is carried out in groups by resistance welding, in time with the step-by-step tube feed, at the welding station, with a fixed lower electrode (5a) and a movable upper electrode (5b). The bolts (7), which are originally somewhat overlength, are at the same time shortened to the desired pipe separation distance. Once the tool (8) has been removed, the intermediate space between the tubes is filled with insulating material. The composite profile is particularly suitable for producing fire-protected door and window frames.

Patent DE-3327995-A1 (DE)
Title: AC tachometer generator
Inventor: FRENK HELMUTH DR
IPC: G01D5/242
Filed: 1983-08-03
Abstract: The invention relates to a multiphase AC tachometer generator whose phase voltages are linearly rectified using a switching rectifier. In this case, a particularly small ripple is achieved by using only the environment of the extremes if a generator is employed which generates flattened sinusoidal curves. The phase voltages converted into square waves deliver the signals for actuating the switches after logical combination. By additionally converting the phase square-wave voltages, it is possible to achieve directly a tacho DC voltage whose sign depends on the sense of rotation. <IMAGE>
