Patent DE-3308189-A1 (DE)
Title: Telephone subscriber device in each case with an identification signal transmitter and an identification signal indicator serving to transmit or receive identification signals
Inventor: STREHL HERBERT
IPC: H04M1/57
Filed: 1983-03-08
Abstract: In response to an incoming call, depending on the position of a manually operable switch, the identification signal transmitter of the B-subscriber is activated even in his absence, whereupon a reciprocal identification signal exchange begins; the identification signal of the A-subscriber transmitted to the B-subscriber is first stored in an identification signal receiving memory along with call time information supplied by a local timer and, when this memory is subsequently interrogated, the call identification signal and the call time are shown together on the display of the B-subscriber.

Title: Device for treating the airways with hot air
Inventor: HIRTZ HANNS-JOACHIM
IPC: A61M16/10
Filed: 1983-03-31
Abstract: A device for treating the airways with hot air, in which a space provided with a heating device is connected in front of a mask to be placed onto the face of the patient, has electrical heating elements which are provided with PTC resistors, so that the heating power is adapted more quickly and more uniformly to the temperature variations of the air to be inhaled, which mainly depend on the breathing behaviour. In comparison with a thermostat-controlled heating element, the load on the heating element and on the allocated parts is also less. Susceptibility to failure is also reduced.

Title: Valve arrangement for controlling the brake pressure in a motor vehicle brake system
Inventor: REINARTZ HANS-DIETER
IPC: B60T8/26
Filed: 1983-06-16
Abstract: A valve arrangement for controlling the brake pressure in a motor vehicle brake system is proposed, which is arranged between a brake pressure source (1) and at least one wheel brake (8, 9). The valve arrangement (6) has two control valves, functionally connected in parallel, controllable by the pressure of the brake pressure source (1) and coaxially arranged in series in an essentially cylindrical housing, one control valve being designed as pressure reducing valve and the other as adjustment valve. The two control valves are arranged in tubular bodies (29, 42) and have a control piston (23, 50), displaceable against the force of a control spring (26, 58) as a function of the pressure; the closing members (27, 51) of both control valves (23, 50) can be applied against a valve seat (28, 48) formed on the tubular body (29, 42). The control spring (58) of the pressure reducing valve can be supported on a support element (60) connectable to the tubular body (42), the axial distance of which support element from the valve seat can be adjusted when the valve closing member (51) is bearing on the valve seat (48). With a design of this type, precise preadjustment of the reversing pressure of the pressure reducing valve is possible, largely independent of manufacturing tolerances. <IMAGE>

Title: Method and circuit arrangement for improving the reproduction quality of electro-acoustic transducers
Inventor: PFLEIDERER PETER DIPL ING
IPC: H04R3/04
Filed: 1983-11-28
Abstract: To improve the reproduction quality of an electro-acoustic transducer, the analog audio signal which is to be converted into acoustic vibrations is converted into a sequence of primary digital signals. The primary digital signals are fed to the data inputs of a microcomputer. With the aid of a program stored in a programmable read-only memory in the microcomputer and the similarly stored parameters of the electro-acoustic transducer which define the real transducer characteristics, the primary digital signals are converted into secondary digital signals. Temporary differences occur particularly with sudden changes in the level of the audio signal. The sequence of secondary digital signals emitted by the microcomputer is converted into an analog control signal. Following amplification, the latter is used to control the electro-acoustic transducer.

Title: Method for the production of castings from aluminium alloy and of pistons composed of an aluminium alloy
Inventor: TAKASUGA SHUNZO
IPC: B22D19/00
Filed: 1984-05-17
Abstract: A casting method for the production of castings from aluminium alloy, in which porous metallic material is fixed in a casting mould and a melt consisting of aluminium alloy is introduced into the casting mould in order to surround the porous material. The method is a high-pressure composite die-casting method and operates at a pressure of at least 392 bar in order thereby to obtain an aluminium-alloy cast blank with an embedded porous material. The cast blank is heated to a temperature of 450 to 550 DEG C and held at this temperature from 1 to 10 hours. This gives rise to an intermetallic composite layer consisting of aluminium and the metal of the porous material at the interface between the porous material and the aluminium alloy.

Patent DE-3437966-A1 (DE)
Title: Ozone generator
Inventor: MANZ ROLF DR ING
IPC: C01B13/10
Filed: 1984-10-17
Abstract: In ozone generation, the oxygen-containing process gas is normally compressed to a pressure of 1.6 bar and blown down again after the process has been completed. According to the invention, the internal energy of the process gas is to be utilised for generating mechanical work energy. If this process is carried out upstream of the ozone apparatus, letting down of the gas causes a lowering of the temperature. This eliminates the cost of additional cooling of the process gas. <IMAGE>
