Title: Power supply system on board ship - has auxiliary generators connected by antiparallel choke coils to two distributors for main switching network
Inventor: SCHILD WOLFGANG
IPC: H02H9/02
Filed: 1979-11-15
Abstract: The power supply system on board ship includes two generators for the main driving propellers and a number of generators connected by pairs of choke coils to two main distributor lines and a large number of switches. Each pair of chokes is magnetically coupled and connected by switches to the lines in anti parallel. The main generators are connected by single chokes by further switches to the lines. The short circuit flow is reduced by one choke of a pair after a short circuit in one of the other switching members. After the momentary energy requirements of the generators, they receive current either singly or in parallel from the chokes connected by the switches of the system. The short circuit flow is independent of the type or the size of the generator.

Title: Arched mine or tunnel gallery support rock joint - has concrete type filling pressed into textile tube through hole between ends
Inventor: DUERRFELD DIPL-BERGING DR-ING
IPC: E21D11/15
Filed: 1979-12-13
Abstract: A textile tube is inserted across the periphery of the arch being joined on. Its ends are closed, and it is filled with hard-setting material under pressure, in provision for attaching esp. arched gallery support units to the rock face, in mines and tunnels. The textile material is opened at a point between the ends, and the tube is filled through this opening. The tube is then almost or completely closed again, and the filling process is interrupted as soon as filling pressure exceeds a prescribed level. The opening may be subsequently sealed. This permits filling at the most favourable point on the frame periphery, and damage to the tube is prevented.
Patent DE-2951947-A1 (DE)
Inventor: UEDA MAKOTO
IPC: H02P8/02
Filed: 1979-12-22
Abstract: An electronic timepiece has a stepping motor comprised of a stator, rotor and driving coil. A wave shaping circuit produces normal driving pulses and correction driving pulses having a longer pulse width than the normal driving pulses. A rotor rotation detection device detects rotation and non-rotation of the rotor after normal driving pulses are applied to the driving coil and in response to detection of a non-rotation condition, a correction driving pulse is applied to the driving coil. A magnetic field detection device detects the presence and absence of an external alternating magnetic field and in response to detection of a magnetic field, a driving pulse of longer pulse width than the correction driving pulses is applied to the driving coil to effect rotor rotation. The magnetic field detection device operates before the normal driving pulses are applied to the driving coil so that in the event of detection of a magnetic field, a driving pulse of sufficiently long pulse width will be applied to the driving coil to effect rotor rotation. In response to detection of an external alternating magnetic field by the magnetic field detection device, operation of the rotor rotation detection device is inhibited thereby conserving power and preventing mis-operation of the stepping motor.

Title: Noise-absorbent facade wall - has pipes for heat transfer medium in ribs separating outer surfaces
Inventor: SCHLOBIES CHRISTOPH DIPL PHYS
IPC: F24S10/75
Filed: 1980-03-06
Abstract: The facade comprises an evacuated wall, whose two outer surfaces are held apart by ribs (3). Pipes (8) pass through or are fixed to the ribs, a heat-transfer medium flowing through them, so as to transfer heat from the ribs and also from the outside wall surfaces (1). One or both of the latter can be formed by arched panes of glass, while a solar heat absorber can be mounted in the evacuated space. The wall can act as a noise insulator, the ribs being designed to give maximum noise absorption. The glass surface furthest from the sun can be reflective, so as to increase the amount of light striking the absorber and increase the heat-insulation effect. The ribs can be made reflective also.

Title: Digital control system for ultrasonic phased array - uses interruptions of clock signal to control intermediates storage via CCD delay lines
Inventor: GEBHARD WOLFGANG DR RER NAT
IPC: G01S7/52
Filed: 1980-03-18
Abstract: The control system uses CCD delay lines. The transmission or reception signals to be delayed are temporarily stored in CCD delay lines of equal length by interruptions of a common clock frequency. These interruptions are each controlled by the output of a respective counter coupled to a start-stop logic. The interruptions may correspond to the time taken for the counter to count backwards to zero from an initial value. A required scan angle can be obtained by a preset linear increase in the counter states, while a quadratic increase is used to obtain variable or parabolic focussing of the sound beam. The direction of the latter is varied by adjusting the clock frequency. The phased array is used for workpiece flaw detection or analysis or for ultrasonic medical diagnostic appts.

Title: Expanding plastics dowel esp. for mitred joint of door frame - has internal tapered zone to seat screw head and thin end flange
Inventor: RIECKE ERNST HERMANN ING GRAD
IPC: F16B13/12
Filed: 1980-05-17
Abstract: An expanding dowel of plastics is intended for joining together two members which meet at an angle, for example for fixing the mitred joint between two door frame members. The dowel consists of a hollow sleeve with two opposite longitudinal slits to assist its expansion. At the open or rear end there is a thin flange and at some distance from this flange, there is a hollow conical taper pointing towards the closed point of the sleeve. The flange is pref. at an angle other than 90 deg., more specifically at 45 deg. to theaxis. The two longitudinal slits pref. lie in such a plane passing through the axis that this plane intersects the flange at the same level on the two opposite sides. The flange is pref. less than 0.8 mm thick, pref. 0.5 mm thick. With this arrangement, the flange does not form any part of the fixing, i.e. does not have to bear the force of the screw head since the screw is concealed inside the dowel. Consequently the flange can be made extremely thin. Also, shorter screws can be used than was previously possible.

Title: Pebble bed reactor side reflector supported on columns - to eliminate direct connection to hot gas ducts
Inventor: FRITZ ROLF DR ING
IPC: G21C11/02
Filed: 1980-12-19
Abstract: Side reflector for a nuclear reactor, esp. gas-cooled reactor with a core composed of spherical fuel elements (pebble bed reactor) is a hollow cylinder (annulus) composed of connected reflector blocks. The bottom of the side reflector surrounds the bottom reflector, which is supported by columns from the bottom support plates. The space between bottom reflector and bottom support plates constitutes the hot gas header or collection chamber. The side reflector also constitutes the container for the core and has radial struts to transmit radial forces to the side thermal shield and the line. The side reflector itself rests on support columns bearing on the bottom plates; the radial outer boundary of the hot gas header is provided by the insulated thermal shield and liner, while between the outer wall of the side reflector and the thermal shield and liner there is an annular seal. This annular seal is pref. situated above the hot gas duct, is horizontal and bears against the outer face of the side reflector. Used for a gas-cooled reactor of the pebble bed type. With a previous arrangement where the hot gas duct is connected directly to the side reflector, considerable stresses arise due to temp. and/or gas pressure transience and due to radial displacements of the side reflector. The new arrangement overcomes these difficulties and eliminates such stresses.
