Title: Loudspeaker cone for motional feedback systems - has thin flexible electrodes built into cone membrane
Inventor: MEGGL FRIEDEMANN DIPL ING
IPC: H04R3/00
Filed: 1976-06-15
Abstract: The loudspeaker cone construction for motional feedback systems allows movement in the cone to be detected and provides a system which operates over the entire audio frequency range. The speaker cone (1) is given an electrically-conducting coating of aluminium or beryllium. This is covered by a thin, compressible layer of plastic or paper between 1/1000 mm and 1 mm thick. The upper surface of the insulating layer is covered by an intermediate layer (4) and finally by another metal coating. The two metal layers form the electrodes of a capacitor, one being connected to a DC polarising potential and the other to a preamplifier. The integrated output of the amplifier is taken to the non-inverting input of the loudspeaker driver amplifier.

Title: Motor cycle fuel tank cap - has attitude sensor valve to shut off air bleed passages at inclination beyond preset limit
Inventor: HUKUTA MASAKAZU
IPC: B60K15/04
Filed: 1976-10-04
Abstract: The motor cycle fuel tank cap has air passages providing communication between the external atmosphere and the atmosphere and the interior of the fuel tank. An attitude sensor is located on one of these air passages. When the motor cycle and hence the fuel tank and fuel tank cap are in a normal, upright attitude this permits free passage of external air into the fuel tank. When the motor cycle is inclined more than a certain amount, suitably (+-) 5 deg., from the normal upright attitude it seals the passage. Leakage of fuel, either gradual or rapid, is prevented. Upon return of the motor cycle to a normal attitude, the attitude sensor automatically re-opens the passage, so permitting continued entry of external air into the fuel tank.

Title: Nuclear fuel rod joint arc welding - striking and ending arc from non-consumable electrode on massive end cap to can
Inventor: ENNERST KARL DIPL ING
IPC: G21C3/10
Filed: 1976-12-06
Abstract: A tight seal is achieved by arc welding with a non-consumable electrode between the tubular can and the end caps of fuel rods for nuclear reactors by a special procedure. The arc is struck outside the joint on the massive end cap, directed into the joint to produce a butt seam, and is finally deflected again to the massive end cap where it is switched-off. The system prevents any weakening of the seam by hairline cracks or slag inclusions. The higher corrosion risk by plutonium- and uranium- contg. residues accumulating in the weld pool end and causing additional corrosion hazards has been cut out.

Title: Hollow HV power cable designed for optional cooling - permits introduction of coolant tube if cable load increases after long period of use
Inventor: RASQUIN WERNER PROF DR ING
IPC: H01B7/42
Filed: 1976-12-22
Abstract: An internally cooled high voltage cable is constructed in the form of a hollow conductor with a cooling tube led through it in which the diameter of the central hollow part of the conductor (1) is 1. 1 to 1, 5 times greater than the external diameter of the cooling tube (5). A heat transfer medium may be used to fill the gap between the outer wall of the cooling pipe and the inner wall of the conductor. This arrangement permits the setting up of the cable without the cooling tube, and the subsequent drawing of the cooling tube if the load on the cable increases after a period of use so that cooling becomes necessary.

Title: Automatic liq. conductivity measurement - has Q output of divider and counter set to logic O by flip=flop for digital programmer controlling valves
IPC: G01R17/06
Filed: 1977-02-22
Abstract: Automatic monitoring is for the conductivity difference of liq. media probes samples fed to measuring cells. A setting circuit sets the programme register the divider counter and flip-flop. The Q-output of a divider and a counter are set to a logical 0 by way of another flip-flop. A switch and divider form 1 s and 30a pulses from the 50Hz mains. The 30s pulses are fed to the programme register. After 30 seconds the Q-output of the flip-flop is switched to a logical 1. This controls a relay which, in turn, controls a valve which admits a high conductivity water sample. A similar arrangement controls a second relay to admit the low conductivity water sample and permit the comparison phase of the cycle to begin.

Title: Deicing system for evaporator of heat pump - has temperature and air humidity sensors generating deicer switching signals
Inventor: MENDLER WILHELM DIPL ING
IPC: F25D21/00
Filed: 1977-03-17
Abstract: The deicer is used for evaporator in refrigeration circuits, especially in heat pumps. The evaporator and ambient temperatures are sensed, and a differential signal is generated for deicer switching. Deicing is started for narrower temperature differences when the ambient temperature drops. The temperature difference signal is corrected by a heat responsive element (30) and a humidity sensitive element (32). The differential signal is influenced, in relation to the air humidity in the vicinity of the evaporator so that with increasing air humidity, the deicing process is started over a lower temperature range between the measuring points and vice-versa.

Title: DC supply circuit fed from AC mains - uses oscillating transistor voltage converter to derive voltage from AC mains and has storage capacitor in starting unit
Inventor: KNOEDLSTORFER JOHANN
IPC: H02M3/338
Filed: 1977-03-24
Abstract: A circuit arrangement is used to derive a DC supply from an AC mains source. It includes an oscillating transistorised voltage transducer which is set in operation by means of a starting unit containing a transistor. The starting unit includes a reservoir capacitor (3) which is charged by way of an ohmic resistor (R5) from a DC source derived by rectification of the mains AC. The output of the starting transistor is fed to a threshold value circuit (GR5). When the instantaneous voltage across the reservoir capacitor exceeds the threshold voltage, the transistor switches on and commences to oscillate. The time constant of the reservoir capacitor and the charging resistor is very large in comparison with the period of oscillation of the voltage transducer circuit.

Title: Infrared gas analyser - using tiltable filters before gas-filled receivers for better selectivity
Inventor: DEPTOLLA UDO ING GRAD
IPC: G01N21/37
Filed: 1977-09-29
Abstract: An infrared gas analyser, with two parallel paths for the rays, one through a measuring chamber and the other through a reference chamber, has two gas-filled receiver chambers feeding a diaphragm capacitor to measure the pressure differential. The receivers are preceded by tiltable filters, which reduce the radiation in the overlapping absorption band of the component to be measured and any disturbing component. The distance of the filters from the receivers is adjustable. Used for measuring NO-content in the exhaust gases of motor cars. This improves the selectivity of the analyser in the presence of disturbing gas components, i.e. the lateral sensitivity caused by the disturbance is reduced.

Title: Honey dispensing machine for waffles - using pressurised fluid for honey transportation and dividing into portions
Inventor: SCHMIDT MATTHIAS
IPC: A21D13/08
Filed: 1977-12-29
Abstract: The Parent Patent described a machine for filling honey into waffles. Instead of the original manual operation, pneumatic or hydraulic means are not applied both to transport the honey from the storage tank to the dispensing nozzles, and for the severing of the honey strands into the individual portions. This makes the machine suitable for mass production instead of in small numbers. The honey is divided into exactly equal portions in a hygienic way.
