Title: Centralising bore grinding machine - has regulator for grinding pin rotational speed to control progression of grinding point
Inventor: HOCHMUTH ERWIN
IPC: B24B41/00
Filed: 1976-02-14
Abstract: The machine is for grinding the centralising bores where a grinding pin is driven by the drive equipment of the machine about its own axis and simultaneously about a reference axis parallel to the grinding pin axis. Thus the casing line of the centralising bore can be moved in an oscillating manner at an angle to the reference axis. The drive equipment of the machine contains a speed regulator which suits the speed of the rotation of the grinding pin about the reference axis to the oscillatingly changed spacing between the grinding pin axis and the reference axis. The appropriate grinding point on the workpiece continues with the same or roughly equal speed.
Patent DE-2606527-A1 (DE)
Title: Reactor emergency coolant discharge at fast and slow rates - according to position of primary circuit leak
Inventor: JASCHINSKI GEORG
IPC: G21C15/18
Filed: 1976-02-18
Abstract: A nuclear reactor installation comprises a liquid-cooled, esp. pressurised water reactor, in which the main coolant circuit comprises a pressure vessel and ducting leading out through the surrounding concrete biological shield. The biological shield, together with the reactor pressure vessel, constitutes a close space in which the pressure is monitored in order to actuate equipment for initiating a rapid power reduction if a leak should occur in the main coolant circuit. Pressure measuring devices inside the close space between biological shield and pressure vessel actuate the rapid power reduction equipment only if a leak occurs within the main biological shield, but initiate a slower reduction of power if a leak should occur outside this closed space within the biological shield. Pref. the pressure measuring equipment provides a comparison between the pressure rise inside the closed space and that outside this space. More specifically, the pressure measuring equipment records the difference in pressure between these two spaces. A sudden reduction in pressure by discharge of primary coolant from the circuit is avoided except in the essential cases of a leak within the primary contained space around the vessel. Where a leak occurs in the primary circuit outside the biological shield, a much slower power reduction is possible, and thus the stress loading induced in the primary circuit components can be correspondingly reduced.

Title: Automatic station search tuner for radio receiver - operates in search ranges narrower than broadcast channel or search channel
Inventor: SEIDLER KARL-HEINZ ING GRAD
IPC: H03J7/28
Filed: 1976-03-30
Abstract: The receiver has a circuit for automatic search for transmitters operating in the standard frequency grid and outside it. Certain criteria of transmitters are measured, and when a transmitter worth receiving is found, the search process is halted by means of a special stopping circuit. The receiver has a tuning circuit switched at first in a channel to a first search range narrower than the channel width, and also narrower than the search channel width into which a transmitter of the standard frequency grid would fall. Then it is switched to another search range, also smaller than the channel and search channel widths. It lies between first two search ranges.

Title: IC engine hydrogen injector valve - has hydraulic servo-piston dia. greater than injector valve dia.
Inventor: HAEFNER GUENTHER
IPC: F02M47/04
Filed: 1976-04-10
Abstract: The hydrogen injector valve consists of a valve cone (3) and a valve shaft (4). The valve shaft upper end is coaxial to and firmly fixed to a servo piston (5). The servo piston dia. is approximately three times >= that of the valve shaft dia. The servo piston upper surface (20) is subject to hydraulic pressure from an annular chamber (9) connected to a regulated supply source (21). The valve shaft bore (14) has two guide collars (15, 16) to support the valve shaft and form a chamber (14). The chamber, as well as the lower surface (20) of the servo piston, is subject to hydrogen pressure from a supply source. Since the servo piston surface is three times >= the valve cone surface (3), the valve is held in the closed position. The valve is opened and closed by regulating the two pressures above and below the servo piston.

IPC: H01M10/48
Filed: 1976-05-19
Abstract: The discharge state of a Na/S battery for trucks which has a solid electrolyte sepng. the S-cathodes from the Na-anodes is determined by providing some of the cells with a second Na-anode.
