Title: Spark plug for externally ignited internal-combustion engines
Inventor: LINDER ERNST DIPL ING
IPC: H01T13/54
Filed: 1981-03-14
Abstract: The spark plug is intended for installation in internal-combustion engines and has a screw-in base (2) with a hollow threaded neck (9), at least one earth electrode (6), which is electrically connected to the screw-in base, an insulator (3) with an insulating foot (16), and a central electrode (5), which is arranged on the insulating foot (16) and is connected to electrical means of connection (4) which pass through the insulator (3). A sealing ring (7) is clamped between the insulator (3) and the screw-in base (2). The sealing ring (7) is constructed as a heat dissipating body, operating in a temperature-dependent manner, and regulates the temperature of the insulator foot and of the central electrode by dissipating quantities of heat to the screw-in base (2), which is cooled by the internal-combustion engine. The heat dissipating body operates in that the insulating foot (16) and the central electrode (5) rapidly reach a favourable operating temperature and maintain said temperature despite different loads on the internal-combustion engine. <IMAGE>

Title: Electrical full-protection circuit breaker
Inventor: FLOHR PETER
IPC: H01H71/10
Filed: 1981-03-16
Abstract: The protection circuit breaker having overcurrent, short-circuit and fault-current tripping has a bar-type (straight-through) current transformer (which is connected in its terminal connection region) for detecting the hazardous shock voltages resulting from defective electrical apparatuses, through which bar-type current transformer the connecting leads must be looped one or more times. In order to prevent connection errors in this case, the opening through the current transformer is blocked by means of a covering shutter in the unwired state, its pivoting into the open position opens a normally-closed contact which is connected in parallel with the test-button normally-open contact, and the switching-on and operation of the protection circuit breaker is not enabled until this is done. <IMAGE>

Title: Device for controlling the viscosity of the ink in an ink jet printer
Inventor: SUMITOMO YUJI
IPC: B41J2/195
Filed: 1981-03-26
Abstract: A device for controlling the viscosity in an ink supply system of an ink jet printer comprises a float (207) in a measuring container (205). The density or the specific weight of the float is, for example, approximately 1.062 and thus slightly above the density of the preferred ink. In normal operation, the float is located at the bottom of the measuring container. If the viscosity of the ink and thus its density rises, the float moves upwards in the measuring container. A scanning unit (208) is assigned to the float and provides a control signal if the float moves upwards. When this control signal occurs, a thinning agent is introduced into the ink. <IMAGE>

Title: Device for regulating the polarisation state of a polarised light beam
Inventor: MOHR FRIEDEMANN DIPL ING
IPC: H04B10/25
Filed: 1981-12-21
Abstract: In the device for regulating the polarisation state of a polarised light beam, a polarisation/beam splitter (6) couples out to an optical/electrical transducer (7) only that portion of a light beam which does not have the desired polarisation direction. Two polarisation actuators (4, 5), which act on the polarisation state of the light beam in directions inclined at 45 DEG  to one another, each receive a high-frequency AC voltage signal (A sin omega t, A cos omega t) and a regulating signal (UR1, UR2). The AC voltage signals for the two polarisation actuators are distinguishable from one another. The output signal of the optical/electrical transducer is fed to two mixers (12, 13), and mixed therein with the AC voltage signals. Their output signals are fed via low-pass filters (14, 15) to PI control amplifiers (16, 17) which generate the two regulating signals. <IMAGE>

Abstract: A DC external-rotor motor without a commutator, having an essentially cylindrical air gap (14), especially for driving magnetic disk memories. The rotor (16) of the motor (10) supports a permanently magnetic excitation magnet (13, 13', 13") having at least two pole pairs and a permanently magnetic control magnet (18, 18', 18"). The one pair of poles of the control magnet is constructed asymmetrically in such a manner that the pole of the one magnetisation direction is somewhat shorter in the circumferential direction than the pole of the other magnetisation direction, while the further control pair or pairs of magnetic poles are symmetrical. Furthermore, two rotation position detectors, which interact with the control magnet and are essentially diametrically opposite one another, and an evaluation circuit are provided, to which evaluation circuit the output signals of said rotation position detectors are applied, and which evaluation circuit generates only one pulse per revolution of the rotor. The excitation and control magnets (13, 18) are magnetised in the same direction, or the pole gap (73, 73") which separates the poles of the asymmetric pair of poles either has an alignment different from the other pole gaps or has a step-shaped or hook-shaped design. <IMAGE>
Patent DE-3201965-A1 (DE)
Inventor: BURGER ERICH DIPL ING
IPC: H04J3/06
Filed: 1982-01-22
Abstract: A digital message transmission system has a transmit side wherein two pulse sequences are sampled at the rate of two plesiochronic data clocks and the sampled sequences are expanded by the insertion of additional information in the manner of "positive stuffing." The two pulse sequences including the additional information are transmitted to the receive side in a pulse frame, the procedure being reversed at the proceed side to decode the message. The momentary phase relationship between the two plesiochronic data clocks, in the form of a binary phase word, is inserted as a portion of the additional information. An auxiliary clock signal is derived from a reference data clock signal for use in transforming the phase measurement (difference between a higher and a lower frequency level) into the binary phase word. An auxiliary plesiochronic clock signal, which is plesiochronic relative to the auxiliary clock signal, is derived from the reference data clock signal and the plesiochronic data clock signal (plesiochronic relative to the data clock signal), the auxiliary plesiochronic clock signal being compared in phase to the auxiliary clock signal.

Title: Method for joining rectangular mitred frames and device for carrying out the method
Inventor: HUETTENHOELSCHER NORBERT
IPC: E06B3/06
Filed: 1982-02-02
Abstract: The method and the associated device serve for the joining of rectangular mitred frames. For this purpose, the individual frame bars are placed on receiving units and pressed against fixing slides pushed into the mitre region beforehand and against contact faces on the receiving units. This pressing operation is performed by traversing the receiving units in the direction of the centre of the frame. After this process of alignment, the frame bars are secured against displacement by clamping devices. For the final joining of the frame bars, the fixing slides are removed from the mitre regions and the receiving units with the frame bars situated on them move in the direction of the centre of the frame until the mitre faces are pressed together. After the joining of the frame bars has taken place, the clamping devices are released and the receiving units move back into the original position. The finished frame can be removed. <IMAGE>
