IPC: A01K1/03
Filed: 1980-03-01
Abstract: The animal cage, partic. for birds, comprises a number of walls clipped together, together with a trough-shaped base joined to the bottom of the meshwork sides. A number of individual cages (E), each with a separate base section (1), are clipped together by their sidewalls where these are open, i.e. have no meshwork bars. Clipping can be by means of intermediate frames without bars, parallel to the sidewall outer frames, and joined together by clipping hooks and to the outer frames of adjacent sidewalls.

Title: Protection circuit for automatic domestic appliance - has check indicators and mains cut=out switch for full disconnection of appliance
Inventor: HERRMANN DIETER DIPL ING
IPC: D06F34/20
Filed: 1980-04-15
Abstract: The protection circuit prevents damage due to incorrect operation or to a fault within the appliance. It uses a number of check indicators for possible fault parameters etc., which are combined in a block with a mains switch allowing automatic full pole disconnection of the appliance from the mains network. The mains cut-out switch for the protection may also be used as the main ON-OFF switch for the appliance. The check indicators may be responsive to the operating temp. of the motor windings and used to check that water is present before allowing the internal heating coil to be switched on. The circuit can be used for a programme-controlled dishwasher or washing machine.

Title: Light duty fan rotor wheel or bearing esp. for automobile - has high quality bushing in heavily loaded and heated bore
Inventor: SCHOLL FRIEDRICH DIPL CHEM DR
IPC: B60B27/00
Filed: 1980-04-22
Abstract: A plastics component such as the hub or bearing for a fan rotor, belt drive wheel, cable pulley, coupling, crank or the like has an internal bushing for connecting to the shaft. This bushing is an inlay of a material which is more temp. resistant, mechanically stronger and more creep-resistant than the remaining material of the wheel hub or bearing. Pref. the inlay is injected into the remainder of the component. It is locked into it by close-fitting connecting elements such as projections and recesses. The inlay is pref. of a glass fibre-reinforced thermoplastics or thermosetting material. Pref. materials for the inlay are glass-fibre-reinforced polyamide 6, polypropylene, phenol-cresol or bis-maleic-imide. This arrangement enables the highly thermally and mechanically stressed bushing of the bearing or hub to be made of expensive and resistant material without using such material for the remainder and avoids the use of a mechanical inlay or insert.

Title: Leak detector for washing machines, etc. - shuts off water and power supply when even slot leakage occurs
Inventor: MELSON NIKOLAUS
IPC: D06F39/08
Filed: 1980-10-08
Abstract: Machines connected to a water supply main, such as washing machines, coffee machines, laboratory equipment, etc. incorporate in the power circuit a detector which can be suitably positioned, e.g. on the floor alongside the machine, to detect water leakage, however slow it may be. When activated, the detector operates a relay which closes a magnetic valve in the water inlet conduit, and also switches off the power supply to the machine to prevent further leakage.

Title: Trigger pulse transmitter for driving one or more power semiconductors in a potential-free manner
Inventor: SCHIRL WERNER
IPC: H02M1/08
Filed: 1981-05-11
Abstract: During the period when a power semiconductor (i) is switched on, the secondary winding (17) of a transformer is connected with one connection (18) to the one terminal (15) and with the other connection (19) via two switches (11 and 12) alternately to the one terminal (15) and to the other terminal (16) of a voltage source. In consequence, the transformer is alternately energised and demagnetised. The secondary current flowing whenever it is energised charges a capacitor (22) via a Zener diode (21), which capacitor (22) discharges into the control path of the power semiconductor (i), which path is connected in parallel with a resistor (23). In order to generate a blocking voltage to block the power semiconductor, during the switch-on pauses when the switch (1) is open and the switch (2) is closed, the connection (18) of the primary winding is also connected via alternately operated switches (13, 14) to the two terminals (15, 16) of the voltage source. In consequence, field-effect transistors (1, 2) connected in particular in the path of an invertor bridge circuit can be driven in a complementary manner, in that a corresponding secondary circuit (30-33) is also provided for the second power semiconductor (2). <IMAGE>

IPC: G01F1/34
Filed: 1981-07-21
Abstract: A method for measuring, in particular, the instantaneous fuel requirement of an internal combustion engine by measuring the vacuum of an air-containing gas stream which changes in accordance with the fuel supply.

Title: Circuit arrangement for telephone switching systems, in particular small PABX system, for which external connections can be set up to exchanges requiring loop dialling or DTMF dialling
Inventor: BLOSSFELDT DIETER DIPL ING
IPC: F42B39/30
Filed: 1981-08-07
Abstract: The invention relates to a circuit arrangement for telephone switching systems, in particular small PABX systems, for which external connections can be set up to exchanges requiring loop dialling or DTMF dialling. A transistor combination (T1, T2) designed in the manner of a bistable multivibrator can be inserted into each external line (L1) leading to PABX systems with loop pulse control. For dialling signal transmission, the corresponding changeover of the multivibrator to the high-impedance or low-impedance condition is performed on the basis of numerical information transmitted in coded form by a subscriber station (A1). If DTMF dialling is required, the primary winding of a transformer (Ün) which is coupled with the line (Ln) concerned is connected in the activated condition to the output of a common oscillator component (OB). The individual transformers are activated alternately by a control unit via a switch (T8, T9) comprising the combination of an npn-transistor and a pnp-transistor. The individual transformers are decoupled with high impedance due to the special design of the switch. <IMAGE>

Abstract: The invention relates to a dummy (mock-up) for live-firing practises, especially using anti-tank appliances or cannons, consisting of an element which is in the form of a board and has an outline which approximates to that of the target, the element which is in the form of a board consisting essentially of chipboard which has a bending strength of approximately 35 N/mm<2>, a transverse tensile strength of approximately 0.9 N/mm<2> and a thickness expansion of approximately 0.6%. In the case of a dummy having such material properties, the rounds (projectiles) which strike the element which is in the form of a board produce stamped-out holes which are virtually free of splinters and whose cross-section corresponds to the cross-section of the respective round. In addition, the dummy has particularly favourable oscillation characteristics which enable reliable hit indication by means of sensors.
