Title: Wound capacitor with safety interruptor - uses dielectric foil shrinkable by heat in longitudinal direction for contact breaking
Inventor: SCHILLING RAINER KARL DIPL ING
IPC: H01G4/32
Filed: 1976-02-17
Abstract: The wound capacitor has a shrinkable dielectric responsive to heat and thus interrupting an electric contact. The shrinking of the dielectric takes place in its longitudinal direction. In the capacitor roll cavity is provided an electric lead which is interrupted by the constriction of the foil windings round the cavity. Preferably the lead wire is clamped between two dished pressure elements. Alternately it may be mounted between two blade edges on opposite pressure elements which may be formed by dished diaphragms carrying the blades. The diaphragm edges may be connected in such manner, as to form a closed pressure box, through which the clamped lead wire extends. The cavity may contain a core tube of heat softened material.

Title: Material specific conductivity measurement - uses comparison with reference material at same temp. whose conductivity varies as same function of temp.
Inventor: NEUMAIER PETER DIPL ING
IPC: G01N27/04
Filed: 1976-04-15
Abstract: The specific conductivity of a material is determined from measuring its conductance at a given tamp. Then a reference material conductivity is measured, whose conductivity varies as the same function of temp. It is measured at the same temp. as that of the tested material, and the two conductivity values are compared. In appts. using this method the outputs of the measuring (5) and reference (7) sensors are alternately coupled to an eddy current tester (17) via the contacts (15) of a synchronous switch. Working synchronously with the contacts (15) are further contacts (19, 21, 23) so that the sensor signals are alternately evaluated. A sensitivity adjuster (25) balances the degree of sensitivity of the sensors.

Title: Hydraulic drive for rotating firearm mounting - has hydraulic motor and pipes and valves for accurate positioning
Inventor: ZELLWEGER JUERG
IPC: F41A27/28
Filed: 1976-04-30
Abstract: The drive for rotating the mounting of a firearm in both directions has a hydraulic motor with two connections and a control spool for connecting both connecting lines with a supply line and to a return line. The mounting is held accurately and firmly in a given position regardless of recoil forces on firing. This design also overcomes the loss of firing accuracy due to oil leakages which results in small movements of mounting on firing. The two connection pipes are connected each by additional pipelines and by a flow restrictor to the supply pipe. These additional pipes are provided with non-return valves preventing back flow into the supply pipe.

Title: Conductive tennis ball and court markings - produce signal when in contact to aid umpire in making correct decision
Inventor: HEITLINGER GEB SOHL INGEBORG M
IPC: A63B43/00
Filed: 1976-06-28
Abstract: A signalling device which monitors the contact of a tennis ball on the playing court marking lines, uses electric conductors which are partially enclosed in the marking strips. The spacing of the conductors is about 3mm and they can be embedded in the marking strips on the ground as well as on the top edge of the court net. In order to produce a closed circuit when the tennis ball is in contact with the conductors, the textile surface of the ball is made conductive. Thus a signal is produced which will indicate if and where the ball was in contact with a court line or the net. Each ball is sprayed with an electronically conducting dispersion which produces on the surface within a distance of 3-5 mm an electrical resistance of 500-1000 ohms.

Patent DE-2653442-A1 (DE)
Inventor: AUMANN VITAL LOUIS DIPL ING
IPC: H05K3/34
Filed: 1976-11-24
Abstract: The clamping-soldering socket (20) has an annular base part (3) from whose one side clamping fingers (4) originate, which run in the axial direction. Their outwardly twisted toothed longitudinal edges fix the clamping-soldering socket (20) in a hole (16) in a circuit board (15). The inwardly curved lower ends (5) of the clamping fingers (4) secure the contact with a connecting wire (19) which is inserted into the clamping-soldering socket, and fix said connecting wire (19) in the said clamping-soldering socket. Tabs (11, 12) which form a socket head originate from the other side of the base part (3). The said socket head acts as a stop to limit the insertion depth of the clamping-soldering socket in the hole (16) and forms a funnel-shaped catchment shell. The narrow tabs (12) which are bent downwards and outwards are in contact with the upper surface of the circuit board (15) and an upper conductor (17) arranged there, as a result of which the thermal and electrical contact with the upper conductor is improved. The design of the clamping-soldering socket (20) ensures that a capillary effect occurs when the connecting wire (19) is inserted, as a result of which the liquid soldering tin rises up the hole (16) and fills the intermediate spaces. <IMAGE>

Title: Warp creel bobbin - gives yarn with one thread marked in measured lengths
Inventor: KLEINERMANNS KARL
IPC: B65H55/00
Filed: 1976-12-30
Abstract: The creel bobbin for use in a creel for the delivery of warp yarns, has >=1 of the threads in the warp marked off in lengths to act as a measurement control. The threads of the warp are twisted together to be at least doubled, and are joined together at the length marking point, by knotting. In the movement path of the warps there is a length counter, to give measured lengths of 55-65 m, acting in conjunction with a knotting unit to mark the measured lengths on the warp. The system provides a simple and positive length marking process for use in winding warps on to a warping beam.

Patent DE-2722863-A1 (DE)
Inventor: BECKINGER GUENTHER DIPL ING
IPC: H04Q3/545
Filed: 1977-05-20
Abstract: The telephone switching system has a central program controller (ZS1) and subcontrollers (TSt, ASt, XSt) for driving passive circuit units (e.g. TS1, TS2). The task consists in preventing the corresponding passive switching units (e.g. TS1, TS2) from executing wrong functions in the case of malfunctioning of the subcontrollers (TSt, ASt, XSt). This is achieved by the switching states allocated to a faulty or faultless operation being stored in a switching state memory (e.g. SZS1) and the passive circuit units (e.g. TS1, TS2) being set to a function-free initial state in the case of malfunction. <IMAGE>

Title: HV ignition lead for IC engine - incorporates capacitance within cable by provision of electrode surrounding tubular conductor
Inventor: SKOWRONEK BERNHARD
IPC: H01B7/00
Filed: 1977-05-28
Abstract: The ignition of the mixture in an internal combustion engine can, in certain circumstances, be improved by increasing the energy in the discharge across the sparking plug electrodes. This has been done by adding a capacitor to the HT circuit as a separate item mounted on the sparking plug. A solution saving both space and components is to incorporate the required capacitance within the HT lead by adding an electrode layer (13) around the conductor (11). The conductor is pref. placed around a central dielectric core (10) to increase its surface area. The cable dielectric (12) separates the conductor (11), forming one plate of the capacitor, from the screen (13), forming the other. An outer sheath (14) protects the whole lead.
