Title: Automotive compressed air vent valve - has flexible membrane ring section covering two circular sectioned vent chambers
Inventor: INGENLATH NORBERT DIPL ING
IPC: F16K17/04
Filed: 1976-08-21
Abstract: The membrane air vent valve for vehicular compressed air installations has a membrane of flexible material, which is tensioned to the housing centrally. Its ring section extending from the centre to the edge area covers a vent chamber. At least two circular sectioned vent chambers (2, 3) with common circle centres coaxial to the membrane (10) are provided, between which are radial housing walls on the face surface of which the membrane locates in a sealed fashion with its ring section. Between two adjacent vent chambers (2, 3) are two housing dividing walls which define a closed, circular section chamber. A support plate (11) locates against the membrane (10) on the side turned away from the vent chambers (2, 3).

Title: Continuously variable DC source - is controlled by pulse width variations within pulse train controlling switching transistor
Inventor: PELTZ GUENTER
IPC: H02M3/158
Filed: 1976-09-22
Abstract: A power source provides a continuously variable DC output without the use of potentiometers. The output level is a function of the width of pulses within a continuous train derived from an external source. A constant DC level (3) is derived from any suitable source, i.e. a battery or zener diode (1), it is fed to the non-inverting input of a negative load resistance differential amplifier (4). The output from the amplifier is fed to an orthodox smoothing circuit, this same output point being connected to a reference level via a switching FET or HF bipolar transistor (5) itself being controlled by the incoming pulse stream (16).

Title: Reinforced concrete floor construction - has in-situ cast concrete galvanised in steel shell which forms part of structure
Inventor: REICHE LUTZ DIPL ING
IPC: E04B5/04
Filed: 1977-01-14
Abstract: The floor system comprises in-situ reinforced concrete cast in a galvanised steel shell which remains as part of the structure. The shell has ribs which, when filled with concrete, act as supporting beams. The sides of the beams have a stepped profile for a good bond between the concrete and the metal shell. The bottom of the shell is widened to accommodate specially formed shear reinforcement. The system requires little form work and requires less steel reinforcement than conventional beams.

Title: Analog video tape recording and playback - splits video signal into components of equal bandwidth and records them in parallel on longitudinal tracks
Inventor: CHRISTIANSEN HANS-MARTIN DIPL
IPC: H04N9/797
Filed: 1977-02-28
Abstract: The procedure of analog video signals recording and playback uses a video tape recorder which splits the video signal into a number of components of narrow bandwidth and records these components in parallel, each in a longitudinal track on the tape. For replay the components are reassembled into the original signal. All the components have the same bandwidth. Thus the recorder can employ stationary video heads and 1/2 inch magnetic tape, which can run at a relatively low speed.

Patent DE-2733454-A1 (DE)
Inventor: SCHIPPERS HEINZ DIPL ING
IPC: D02G3/36
Filed: 1977-07-25
Abstract: A method is provided of producing a core-sheath yarn in which a core yarn is continuously guided in a spinning zone through a gap formed between two adjacent surfaces moving in opposite directions, and staple fibres are fed into the path of the core yarn in such a way that the staple fibres come into frictional contact with the moving surfaces. The core yarn is thereby covered with the staple fibres. The core yarn is guided into the spinning zone at a first defined speed and after covering with staple fibres is drawn off again at a higher second defined speed so as to produce a defined predetermined elastic elongation of the core yarn in the spinning zone. A preferred apparatus for this purpose comprises two rotatable drums (1) each with a porous sleeve in whose interiors are provided air suction devices and between which is defined a narrow gap in which in use the fibres to form the sheath core supplied as individual fibres are collected and spun. A first delivery mechanism (14) is arranged upstream of the drums (1) and a second delivery mechanism (16) is arranged downstream of the drums (1) for the defined supply of the core yarn (3) into the spinning zone and for the defined takeoff of the spun core-sheath yarn from the spinning zone. Means are provided for driving the delivery mechanisms at an adjustable gear ratio. <IMAGE>

Title: Electron tube cathode heating circuit - has series resistor ensuring constant heating power for cathode on change of resistance
Inventor: BOHN JOSEF DIPL ING
IPC: H01J19/04
Filed: 1978-08-08
Abstract: The circuit comprises a heating voltage source and a series resistor (ST). It is intended for increased service life of the electron gun system, with sufficient electron emission. For this purpose, it is heated with a constant power output, while measuring the voltage drop at the heater (KH), as well as the heating current. The circuit forms the product of these two magnitudes, and the resistor (ST), forming a setting element in the circuit, is so controlled as to keep this product constant. Alternately the setting element can be replaced by a series resistor whose value corresponds to that of the cathode heater in operating state. The measuring signals may be supplied to both inputs of a multiplier (ML) whose output has a constant value.

Abstract: Vertical steam generator with natural circulation comprises a cylindrical shell, a bundle of U-tubes, through which the primary liquid flows, a single tube plate a moisture separator above the tube bundle for removing water droplets, from the steam produced in the secondary circuit, and a dryer above the moisture separator. The space beneath the tube plate is divided by a partition into inlet and outlet chambers for the primary liquid. The tube plate together with tube bundle constitutes one unit, the steam generator and drier constitute two separates units, and the main exchanger shell and cover constitute two further separate units. All these units can be separated for repair, maintenance and replacement. The units are connected together by connecting elements. The tube bundle can be removed and replaced or repaired without the need to remove the steam generator shell. Connections between the heat exchanger and the rest of the plant require disturbance for repair and access work. In replacing the internal components, it is possible to introduce more up-to-date designs.
