Patent DE-2354452-A1 (DE)
Title: Workpiece retention pressure cylinder - works with control disc incorporating inner toothing and electro-magnetic activation
Inventor: KUNERT WERNER
IPC: B25B5/06
Filed: 1973-10-31
Abstract: The pressure cylinder is for the firm retention of workpieces and the enactment of a movement transmission or like process for the purpose of a piston advance or rotary movement either before, after or during an advance movement. Under the influence of the device which causes the advance movement, a control disc puts into effect the advance and rotary movement. The movement of the control disc is transmitted by an inner toothing arrangement, and for the stroke or advance movement the control disc is separately operated independently of the activating force, being electro-magnetically constructed.

Title: Remotely adjustable driving mirror for motor vehicle - has cable drives for tilt and inclination
Inventor: MUELLER HORST
IPC: B60R1/06
Filed: 1973-11-07
Abstract: The driving mirror is mounted in special holders which allow it to swivel about a vertical axis and tilt about a horizontal axis. Two cable drives are provided, one attached to each holder with the operating ends of the drives mounted together on the dashboard. The driver is then able to adjust the mirror from the driving position. The design enables the drives to be looped around awkward body sections without design change. Also the nearside mirror is also fitted with controls in a simpler manner than would be achieved with rigid mechanical linkages.

Title: Hingeing pipe connection - pipe flange with curved sides flange and clamp plate of other pipe
Inventor: LENSE EUGEN DIPL ING
IPC: F16L27/053
Filed: 1974-01-31
Abstract: The pipe connection is especially suitable for large bore exhaust pipes of large high speed vehicle engines. A sliding ring with a convex curved surface at each side is welded on the end of one pipe. The curved surfaces have equal radii, the centres of which lie on the centreline of the pipe. A flange with internal concave surface is welded to the other pipe. This flange lies against the sliding ring and is pressed against it by a ring, which also has a concave surface. This ring is mounted behind the sliding ring and is connected to the flange by bolts and nuts. The bolts pass through large clearance holes in flange and ring, while a distance tube with large clearance hole is mounted between bolt head and ring. The distance tube allows relative angular movement between the flanges and the two pipes.

Title: Trigger for interference amplitude suppression - consists of two-stage transistor amplifier of Schmitt-trigger type
Inventor: SCHELER MANFRED DIPL ING
IPC: H03K3/2893
Filed: 1974-02-11
Abstract: The trigger circuit is intended for badly distorted signals. The amplifier input stage is controlled through a coupling capacitor by the input signal, and its base voltage mean value is adjusted through a voltage divider. Time constant determined by the coupling capacitor and the base voltage divider is so large in relation to the time spacing between useful amplitudes, that the charge losses of the coupling capacitor between two useful amplitudes matches the required signal-to-noise ratio. When the trigger has two transistors of the same conduction type coupled through a resistor, the input transistor base is connected through high value resistors to the output transistor collector and emitter.

Title: Large pebble bed power reactor with uniform burn-up - obtained by shaped block above single discharge funnel
Inventor: LOHNERT GUENTER DIPL PHYS DR P
IPC: G21C19/20
Filed: 1974-02-25
Abstract: A device for producing a uniform through flow of fuel spheres in a large pebble-bed reactor comprises a single bottom funnel-shaped outlet with an internal cone-like block mounted, apex downwards, just above the funnel, leaving sufficient space below the block to permit the downward flow of the spheres. This block may be rhombus-shaped with rounded corners, as viewed in longitudinal section, propped by columns or webs from the base of the core bed. Where the core vessel is cylindrical, the block is of about half its dia. Thoroughly uniform residence times are attained across the whole cross-section of the vessel, thus ensuring uniform burn-up. This enables the Otto programme (once through then out) to be used.

Title: Air evacuation channel for pressure die casting machines - using sintered disk stopper, porous to gas but not to molten metal
Inventor: JAERKE PAUL
IPC: B22D17/00
Filed: 1974-04-04
Abstract: A suction device for the controlled de-aeration and/or evacuation of the dies in pressure die casting machines where a suction channel is connected to the die cavity, uses a sintered insert to close the end of the suction channel. The sintered component is pref. a disc located in the end of a vacuum insert in the moving die half, and the disc is pref. used together with a stopper rod, the head of which has a conical seating face which butts onto a shoulder in the hole leading to a second suction channel connected to a vacuum reservoir. The end surface of the stopper rod head may be concave or convex and may be used as an ejector rod. Used for removing air from the die-cavity in pressure die casting of e.g. Al. By using a stopper disc porous to air or gases but not to molten metal, the air suction channel is effective until actually closed by the molten metal, i.e. the removal of air is very efficient.

Title: Cct for automatic changeover from iron oxide to chromium dioxide tapes - has erasing oscillator and regenerative repeater
Inventor: CRANTZ DIETER DIPL ING
IPC: G11B5/008
Filed: 1974-04-09

Title: Group control of several DC motors - motors of similar size and have automatic speed-dependent change-over arrangement
Inventor: ETTLINGER GUENTER ING GRAD
IPC: H02P3/08
Filed: 1974-08-08
Abstract: Electrical plant with similar D.C. motors has a common supply with a voltage control and a line with current control. The motors can be switched to one of two lines. The voltage of one line is limited by a voltage of the other line. Thyristors disconnect diodes and switching over from one line to the other. The current flow is broken for a short period by a commutator arrangement and the thyristor firing circuit is simultaneously switched off. In arrangements with several drive groups the two supply lines to each group are fed from a separate rectifier bridge. The bridges are connected to intermediate bus bars and then to the mains via a potential divider.

Title: Hydraulic control valve - controls number of hydraulic operated devices carrying different loads
Inventor: HAWLEY FREDERICK JOHN
IPC: F15B13/02
Filed: 1974-08-23
Abstract: Typical application of the arrangement occurs on hospital beds, where it is required to enable the personnel to lift lower the bed either maintaining the horizontal position regardless of the different loads on the four points of support due to the random position of the patient's body, or to be able to lift or lower the bed and tip it into any required position for investigation purposes. The basic idea of operation is that a valve system controls the flow of the hydraulic fluid to the various power units in accordance to the load prevailing on a particular unit, always registered in the form of a fluid back pressure.

Title: Closed cycle energy production system for turbo generators - working medium is refrigerated at each compressor stage
Inventor: LINDE GERHARD DIPL ING DR
IPC: F25B15/04
Filed: 1974-11-21
Abstract: The working medium, which could be air, helium or nitrogen, is compressed, heated and then expanded to produce working energy in a closed cycle and then cooled to approximately environmental temperature and repeatedly recycled. In order to economise on the energy required for the compression, the working medium is refrigerated in a closed circuit refrigeration system to a temperature preferably 10 - 50 deg.C below that of the environmental temperature before each successive compression stage. The expanded working medium is refrigerated by a first heat exchanger with the expulsion side and then a second heat exchange with the evaporation side of the refrigeration absorbtion cycle, with water cooling provided between the two refrigeration sides and then returned to the inlet side of the compressor.
