Patent DE-2419372-A1 (DE)
Title: Capacitive integrated semiconductor cct. - has doped substrate and parallel layers doped to opposite conductivity embedded in substrate
Inventor: MEUSBURGER GUENTHER DIPL ING
IPC: G11C11/404
Filed: 1974-04-22
Abstract: The integrated single-transistor memory storage element of capacitive type has a substrate doped into a first conductivity state. The locations intended for the capacitors are provided with several parallel layers doped into an opposite conductivity state. The embedded layers are connected in parallel by a connecting layer of identical conductivity. Preferably the layers are parallel to the substrate surface, one of them abutting the substrate surface and forming an inversion layer. Typically the substrate and the layers are of silicon. The layers are typically connectable to a pole of a voltage source, thus forming one electrode of the capacitor, the other one being formed by a metallised track on the substrate with an intermediate insulant.

Title: Synchronous data network - uses switching method by time multiplex exchange of binary data received over data lines
Inventor: FICK HERBERT DIPL ING
IPC: H04L12/52
Filed: 1974-04-23
Abstract: Incoming data are synchronised with a beat determined by the data transmission speed. After their switching through the data are again synchronised with the same beat, but shifted by the transmission time in the exchange. When incoming and outgoing data lines are of the same speed class, a common beat is allocated to all lines. When data lines are of different speed classes, e.g. 2.4, 4.8, 9.6 Kbit/s, a beat is allocated in accordance with the data line transmission speed. Lower speed class data lines form a bunch, in which the beats are shifted in phase with respect to each other in the raster of the highest speed class beat allocated.

Title: Solar collector with black panel and photocells - liquid or gaseous heat carrier circulates between two collector panels
Inventor: MARX PETER DR ING
IPC: F24S23/77
Filed: 1975-05-23
Abstract: Solar collector for converting solar energy to thermal or electrical energy comprises a black panel (3) on which are disposed photocells. A liquid or gaseous heat carrier circulates between two collector panels (3, 5), in a sinusoidal flow device formed by interlocking intermediate webs (6). The black-painted surface of the panel absorbs a very high proportion of light in the visible range, and emits only a small fraction of IR radiation. 1 -3 glass panes (2) may be disposed in front of the collector panel, to allow transmission of sunlight while absorbing the long-wave heat radiation emitted by the collector panel, which increases efficiency of the collector. Mirrors (1) may be disposed at the sides at a given angle to reflect sunlight onto the collector panel.

Title: Disc type throttle valve with low operating torque - has linkage giving straight line valve motion
Inventor: ILLY ALOIS DIPL ING
IPC: F16K1/24
Filed: 1975-06-27
Abstract: A throttle valve has a disc (1) with two diametrically opposite lugs (3). The lugs (3) have holes which fit eccentric bearing bosses (5) on the valve spindle (2). The bearing axis intersects the axis of the valve bore. A pivoted link (7), connects the disc (1) to the valve body (8). The valve spindle (2), the eccentric bearing bosses (5) and the link (7) form a three-link mechanism.

Title: Hot gas engine - has medium charging pipe connected by separate sections to buffer and compression chambers (NL210177)
Inventor: WEINHARDT EROLF
IPC: F02G1/05
Filed: 1975-07-19
Abstract: The hot-gas engine has compression and working pistons working together in the cylinder to form a compression chamber between them, while there is a buffer chamber on the other side of the working piston. From this a capillary flow path leads to the compression chamber, and the working medium is quickly removed from the latter by a short-circuit passage with valve. The working medium is delivered from a receiver via a charging valve to the cylinder to increase the output, while to reduce this a compressor extracts it again. The charging pipe (15) has two sections, one (15a) connected to the buffer chamber (11), and the other (15b) to the compression chamber (3).
