Patent DE-2632929-A1 (DE)
Title: Testing circuit for electric component insulation strength - applies AC voltage and possible breakdown current is rectified and displayed
Inventor: GUENTHER MANFRED
IPC: G01R31/02
Filed: 1976-07-22
Abstract: The testing circuit for electrical devices and components is connected for application of an ac test voltage, and a device detecting a voltage breakdown in the specimen. A current to voltage converter is connected in series with the specimen for conversion of a current flowing in the circuit in case of a breakdown into a rectified voltage. This voltage is applied to an integrator followed by a threshold switch for operation of an indicator. The current to voltage converter can be formed from a resistor placed in series with the specimen, a dual path rectifier bridge being connected in parallel with the resistor. The rectified voltage is taken from the bridge output.

Patent DE-2712140-A1 (DE)
Inventor: BUSER WERNER
IPC: H02H9/04
Filed: 1977-03-19
Abstract: In test stations having a number of mains-powered electronic measuring instruments without protective isolation, earth loops are produced when the instruments are connected to one another both via the protective earth and via the measuring lines. Potential differences which become superimposed on the measurement signals and can lead to interference can occur between the individual protective earth terminals particularly in the case where the protective socket earth is separated from the neutral conductor. On the other hand, an operation without protective earth can lead to dangerously high contact voltages in the case of defects. To solve the problem, a non linear element (D) is in each case connected between the protective earth of the measuring instruments (G1, G2) - if necessary excepting one of these - on the one hand, and the protective earth terminal of the socket (Sd), on the other hand. The protective earth of one single measuring instrument is advantageously directly connected to the protective earth terminal of the socket. In normal operation, the voltage drop caused in the neutral conductor (o) between points A and B due to the current (I) is not large enough for allowing the non linear element to acquire a low impedance so that therefore no noticeable interference to the measurement signal is produced by the current flow via the earth connection. On the other hand, the voltage drop is limited to harmless values in the case of an earth fault. <IMAGE>

Title: Speed control system for rotary nozzles - has torque applied by spray medium which is transmitted to motor and generator rotors
Inventor: HAMMELMANN PAUL
IPC: B05B3/06
Filed: 1977-03-22
Abstract: The speed control system is for rotary nozzles in a spray gun, functioning according to the Segner water wheel principal. The torque applied to the rotary nozzles (1) by the spray medium, is transmitted via a transmission onto the rotor of a generator (22) and the rotor of an electric motor (23). The generator supplies the motor with current and is poled, so that the motor rotor attempts to rotate in a direction opposite to that applied by the transmission. A resistance is located in the connection between generator and motor, and consists of a light source (25), to observe the cleaning process. Generator and motor are positioned in a chamber (24) of a housing (3), carrying the spray nozzles (1). The transmission consists of a planetary one.

Title: Cylinder for rotary fur ironer - with oblique milled grooves and slotted inserts parallel to axis
Inventor: SELBECK HANS GUENTER
IPC: C14B17/02
Filed: 1977-05-17
Abstract: A new cylinder for a rotary ironer of fur skins is longer than the conventional 35 cm. which require a treatment of a fur in several passes, yet has the same good ironing effet and prevents teating of the leather by the higher tensile stresses. The cylinder surface is fitted with milled grooves which are symmetrically arranged at an angle of 17-20 degrees alternating to the right and to the left. In addn., slotted inserts are provided parallel to the axis. The lagging edges of the milled grooves are fitted with flat profile pieces which protrude slightly over the dia.

Title: Nuclear fuel powder prodn. with regulation of isotope compsn. - by joint conversion of various starting materials in required amts.
Inventor: BAYER HEINRICH
IPC: G21C3/62
Filed: 1977-07-27
Abstract: Fuel powder of almost any regulable isotope compsn. within the range of any starting material present is produced by first passing starting materials of varying compsn., i.e. enrichment, in the required amt., without premixing, to conventional conversion processes, e.g. the AUC (ammonium uranyl carbonate) or ADU (ammonium diuranate), and then processing further to the required degree of enrichment. Mixing in the conversion process instead of in the form of the powdered prod. gives absolute homogeneous mixing of the various isotopes (e.g. U-235 andU-238).

Patent DE-2747448-A1 (DE)
Inventor: SAKAMOTO HITOSHI
IPC: H02P23/00
Filed: 1977-10-21
Abstract: This servodevice for synchronising the scanning of helical tracks on a magnetic tape with the revolution of the magnetic heads is used in the recording and replaying of television signals. For this purpose, command signals (Pb) with a particular phase relationship with respect to the position of the rotating magnetic heads (H1, H2), either from a pulse transmitter (P) during the recording or from the recorded information during the replaying are used. Reference signals (Pa) and command signals (Pb) are supplied to a flip flop (21) as phase comparator in order to generate by this means an information on the mutual position of the said signals. A signal processing circuit (24, 25) is used for generating selective information (Pf, Pg) on leading or lagging phase angle. The signal from an up/down counter (15) and a variable phase delay circuit (3) is applied to a drive control (4) for the drive (1) of the magnetic heads. This provides simple and inexpensive control for avoiding low-frequency phase errors, namely a DC drift and high-frequency phase errors, namely synchronisation errors. <IMAGE>

Title: Fire alarm system using delayed detectors - has evaluating circuit for false alarm recognition even after system reconnection
Inventor: WEBER GORDON
IPC: G08B25/14
Filed: 1978-04-14
Abstract: The system has device distinguishing between a continuous false alarm caused by a faulty detector, and a genuine alarm single. It has electronic detectors delivering an alarm signal with a delay (5) after their operating voltage connection, and a circuit interrupting the detector voltage at least once for a presettable period after a first alarm signal.

Title: Doped barium titanate PTC resistor tube - which occupies less space than an equiv. disc PTC resistor
Inventor: GRUBE WINFRIED DIPL PHYS
IPC: H01C1/14
Filed: 1978-04-17
Abstract: The resistor consists of a ceramic tube with a perovskite structure based on n-and/or p-doped barium titanate or substd. barium titanate, this tube being a posistor. One of the electrical connections to the tube is formed by a layer of metal which covers only part of the outside dia. of the tube.

Title: Concrete shuttering panels spacer cross stem - runs through elastic ring, has end supports in pressure plate recesses
Inventor: LAUE HELMUT
IPC: E04G17/075
Filed: 1978-05-12
Abstract: Panels are pressed by a spring element against support members borne on the outside ends of a horizontal bar, on the space retainer for panels used in shuttering for concreting. This transverse bar (3) passes through an elastic ring (5) fitting against the inside of the panels (1, 2). At its outer ends are bent support arms (4) which engage in recesses in a pressure plate (6) mounted on the outside of the panels. The transverse bar can be set in diametrally opposing recesses in the ring while its ends have a bent section engaging the pressure plate recesses. This ensures mutual bracing of form panels, even in lost shuttering with protruding parts easily removed afterwards.
