Patent DE-2802131-A1 (DE)
Title: Adjuster for single point cutter in machine tool - has piston operating adjuster wheel for advancing tool through reduction drive
Inventor: CHRIST ROLF ING GRAD
IPC: B23B29/04
Filed: 1978-01-19
Abstract: The correction setting arrangement is used for a single point cutter of a machine tool on a machine tool slide. The cutting tool is adjusted in one direction by switching pulses and a driving piston. The piston rotates an adjusting wheel through an angle depending on the piston stroke. The adjusting wheel is connected by a coupling acting in one direction to a reduction drive to read just the tool holder. A restoring pulse returns the adjusting wheel to its initial position.

Title: Remote control system for TV - has HF remote control channels to handle various signals for switching load and emergency off-signal
Inventor: WEGENER HORST ING GRAD
IPC: G08C25/00
Filed: 1978-09-16
Abstract: The remote control system has two separate HF remote-control channels for switching the load on and off. Signals for switching the load on and off are sent via these channels in antivalent form. When the antivalence disappears the load is stopped. A first signal can be sent via another remote-control channel to operate a disconnector when an 'emergency-off' function is required. A second signal is applied via gates to both channels and is used to generate the disconnect control signal for the load.

Title: Mounting ferrite core of transformer on circuit card - is by fitting it into slots in card edge to link with printed winding
Inventor: SCHMIDT EWALD ING GRAD
IPC: H01F17/06
Filed: 1979-07-06
Abstract: The object is to simplify the mfr. of a small transformer with a ferrite core.

Title: Locking device comprising double acting hydraulic cylinder - has stop valve piston with seat forming step between housing sections
Inventor: CONRAD ERNST
IPC: F15B15/26
Filed: 1979-07-11
Abstract: The locking device comprises a double-acting hydraulic cylinder with a stop valve, the two cylinder branches being connected by a pipe containing the valve. The latter comprises a piston sliding in a housing with connecting unions for the pipe. Both the piston (8) and the chamber (7) in the housing have two portions of different diameters, joined by a step (9,10) acting as a valve seat. A bore (11,12) each side of the step leads to the pipe connecting unions. When the piston is in the stop position, these bores lead into two annular chambers (13,14). The step can be tapered, and the annular chamber for the smaller diameter part can be formed in the piston itself.

Abstract: The radiator union connects it to rectangular-section pipes laid in the manner of skirting boards, the feed pipe being above and sealed to the return one. It comprises a section of pipe (1) fitting in the alcove, bevelled at the ends for butt-wedlding to side sections (2) of length to suit the alcove depth, these in turn being bevelled and butt-welded to pipe unions pieces (3). Thus a U-shaped stand with arms extending sideways is formed for the radiator (6), with two vertical pipes (5) of equal length extending from it to the latter, to which they are connected by valves (7). The vertical pipes are connected to the first pipe section (1) by sleeves welded in, the return pipe sleeve having an insert screwed into it with a nozzle sized to suit the radiator heat output. At the free end of the insert is a sealing spigot fitting in a hole drilled in the partition between the feed and return pipes.

Title: Solar energy collector with transparent polyacrylic outer tube - provided with Fresnel lenses mirrors and flattened collector tube
IPC: F24S23/30
Filed: 1979-08-16
Abstract: A segment of the transparent PMMA pipe protecting the heat absorbing pipe through which the heat conveying medium flows, in a collector for solar energy, is designed to have the action of lenses and esp. Fresnel lenses, which concentrate the light on to the absorbing pipe. The segment of the protecting pipe opposite to the lenses is made into mirrors, and the absorbing pipe has a flattened cross-section with a width four times its depth. The absorbing pipe is arranged along the focussing line of the mirror segments on supports having a poor conductivity for heat such as PTFE. The collector concentrates as much sunlight as possible on to the absorbing pipe without high reflection losses and too large a mirror surface, so that it is compact and small.
