Title: Earth fault detector in power line section - disconnects line section for very short period and observes delay of unbalance voltage
Inventor: BAUSCH EMIL
IPC: G01R31/02
Filed: 1977-04-15
Abstract: The line section is a part of a three-phase network (10) with earthed or non-earthed neutral. Detection of the earthed section is achieved by brief disconnection of line sections after appearance of unbalance voltage signalling an earth fault. The part of the network affected by earth fault is detected by a network disconnection without interfering with a consumer. Line sections in this network part are disconnected during certain time intervals, with the voltage at certain points disconnected for a period of the order of 250 milliseconds. Decay of the envelope of the unbalance voltage appearing after the disconnection serves as criterion for the section affected by the earth fault.

Title: Thermal lining inside IC engine - consists of thin metal sheet over ceramic insulating material on surfaces subjected to heat
Inventor: HAEFNER GUENTHER
IPC: F02B77/11
Filed: 1977-06-29
Abstract: The engine piston (8) has its upper surface covered with a solld or powdered thermally insulating material (15). This is held in place by a thin sheet (14) of metal which is brought down (16) round the sides of the piston and welded or soldered to it. The insulation (15) e.g. foil or ceramic is sealed by the sheet (14) and is kept at a pressure below the minimum pressure in the cylinder. This ensures that the pressure in the cylinder keeps the metal sheet tight to the piston and insulation. Thin sheet with a low thermal capacity can thus be used. A similar construction is applied to other surfaces in contact with hot gases such as the cylinder walls, exhaust valve and the exhaust passage in the cylinder head.

Title: Pressure vessel for boiling water reactor has dividing plates - between high and low pressure zones around core with annular expansion cap at plate periphery
Inventor: LOHSE KARL-HEINZ ING GRAD
IPC: G21C15/243
Filed: 1978-03-20
Abstract: A reactor pressure vessel for a boiling water reactor has an annular gap between the vessel and the core tank or wall surrounding the core. The annular gap is bridged by a horizontal dividing plate, separating the suction and the pressure sides of a circulating pump mounted in an aperture in the dividing plate. The dividing plate is firmly welded to the core retaining tank and has a slight gap at its outer periphery in the cold state of the reactor. This gap is of such dimension that when the reactor runs hot it is fully closed. The pump casing fits into the aperture with a gap all around. This gap is closed by a rigid sealing element. More specifically, the rigid sealing element may be a ring seated in a groove around the periphery of the casing. A simple and inexpensive arrangement. The completely flat dividing plate is absolutely leak-tight in the hot running state. The actual radial stress in the plate is determined by the relationship between the size of the gap and the thermal expansion of the plate in the radical direction.

Displacement of the elements relative to the element is effected by means of a locking mechanism which carries the elements as a fixed element. Used in optics, photography domestic and industrial illumination.

Title: Deflection circuit for TV receiver - uses temp. independent tilt pulse generator to control horizontal and vertical deflectors
Inventor: HUGO ROLF ING GRAD
IPC: H03K4/83
Filed: 1978-11-25
Abstract: The circuit provides horizontal and vertical deflection in a television receiver under control of pulses which are tilted by a defined amount and whose lengths are modulated by a saw tooth generator signal in two control stages. The pulse generator has a shunt and a series diode, and the signal output is integrated by two RC circuits to give tilted signal pulses. Integrating capacitors are discharged at the beginning of the line sweep and charged during line flyback to give the tilt pulse. The modulated tilt signal switches vertical deflection thyristors to trigger deflector coils. This circuit delivers tilt pulses whose amplitude and flank positions are temperature-independent.
