Title: HV rectifier with stack of series coupled semiconductor components - has taps connected to individual components and to outer contacts of layered capacitor block
Inventor: BEHN REINHARD DIPL PHYS
IPC: H01L25/07
Filed: 1977-02-16
Abstract: The high voltage rectifier is intended as a high voltage cascade for supplying acceleration voltage in cathode-ray tubes. It contains a stack of series connected diodes, mechanically and electrically interconnected. They are also connected to terminals for outer contacting of the diodes, as in 2536711. The terminals (8) are coupled to outer contact surfaces of a layered capacitor block. Preferably the terminals are mutually offset and mounted alternately on opposite sides of the high voltage rectifier stack (10). The terminal ends are bent to provide abutment against the capacitor block contact surfaces. The terminals may protrude from the rectifier stack at right angles and are so spaced as to match the capacitor contact surfaces position.

Title: Integrator for fuel injection metering valve - has opening of orifice varied by piston subjected to pressure controlled by solenoid
Inventor: STUMPP GERHARD DIPL ING
IPC: F02M69/26
Filed: 1977-02-21
Abstract: Fuel is delivered by a pump (14) to a metering valve (7). The fuel passes through passages into the annular groove (18) in a piston from which it passes through further passages into the injection chambers (21). The injection chambers are separated by a membrane (22) from pressure chambers. A branch pipe takes fuel through these to an orifice (35) in the side of an integrator. The integrator contains a spring loaded piston (37) with an internal bore with a throttle (46) in it. Fuel can flow through this from a by-pass contg. a solenoid operated throttle valve. The back pressure on the metering valve piston is varied by the flow through the integrator which in turn depends on the opening of the solenoid valve (43).

Title: Diesel engine cylinder head arrangement - has narrow cooling water circulation passage to avoid thermal stresses
Inventor: ELSBETT LUDWIG ING GRAD
IPC: F02F1/40
Filed: 1977-06-28
Abstract: The engine has a piston (11) reciprocating in a cylinder (2) which has a cooling water jacket (2). The cylinder head contains inlet and exhaust valves and a fuel injector (17). It has no cooling ribs and no cooling water jacket. A small diameter passage (15) runs through the cylinder head and connects with an annular passage (20) round the fuel injector (17). It also runs tangentially into an annular passage (21) round the exhaust valve. The main passage (15) is connected to a cooling water flow and return. Cooling water flows at high velocity through these passages. It removes heat from the parts subjected to high thermal stresses without unnecessarily cooling the rest of the cylinder head. This avoids thermal stresses without reducing combustion efficiency.

Title: Insulation for nuclear reactors - comprising panels of metal sheets enclosing air, with deformable edges preventing convection but allowing thermal expansion
Inventor: SCHOLZ MANFRED
IPC: G21C11/08
Filed: 1977-07-29
Abstract: An insulation partic. for a nuclear reactor, between the outer periphery of the reactor pressure vessel and the inner periphery of the concrete biological shield, consists of rectangular metal sheets with separators between them, enclosing air; the edges of the sheets are folded into a V form giving the edges a dimensional elasticity. When the panels are pressed together the edges are deformed over a distance determined by the separators and the sheets form panels which are fluid tight and in which convection cannot take place. The arrangement provides an insulation in which convection is effectively prevented in and between the panels but such that the different panels form in the packed state a standardised element which can be made economically and installed easily. The element has the necessary rigidity and constant dimensions but in spite of its fluid-tightness in its marginal zone, the different sheets can expand freely in length and width without thermal strain. Marginal bands on each panel are not necessary.

Title: Wind driven machine with solar collector - has slewing wedge shaped guide with rotors at free edges
Inventor: KOERBER ERICH
IPC: F03D9/00
Filed: 1978-02-06
Abstract: The wind-driven machine has one or more rotors on vertical axes and partic. of the finely-polished type. Part of the machine acts as a solar collector having an energy-absorbing core through which a medium flows, extracting the heat for use. A wedge-shaped guide slews on a vertical axis (5) which is nearer to the point (6) of the wedge than the free edges of its faces (1, 2). Wind rotors (7, 8) are mounted at these free edges while one of the faces (2) acts as a solar collector. Between the axis and the guide is a return mechanism which without the effect of wind delays the guide in a position such that the collector face is towards the sun at least when the latter is at its highest point. Wind pressure turns the guide about the axis in opposition to a retarding torque.

Title: Caravan door boarding step - has load carrying part bolted height adjustably to bracket which hinges to match slope of ground
Inventor: BLACH JOHANN
IPC: B60R3/00
Filed: 1978-05-10
Abstract: The boarding step for a caravan consists of the main step part (1) which is roughly L-shaped in end view and a bracket (3) bolted to it, which hanges on a fastening member (6) attached to the chassis (7) of the caravan under the door. The vertical face (2) of the step part terminates at the bottom in a flange (4) to give a good load support. At the other end of the tread surface is a rear face, parallel to this vertical face, against which the lower part (12) of the bracket is clamped by bolts. The upper part of the bracket slopes at an obtuse angle to the lower part. The whole is height adjustable, and due to the hanging support, can adapt to uneven ground surfaces. The lower part has sets of holes (14) vertically above each other, so that the bolts (16) may be inserted at a height to suit the height of the threshold. The upper part incorporates a hook (5) at the top, so that it may be mounted on the horizontal arms (8) of a T-shaped fastening member hanging downwards from the chassis. The fastening can be a pillar, secured by a bolt through the middle, which widens out at the bottom, with a lug each end. The step has two curved ears which fit inside the lugs with a hooking action, being engaged in a raised position, then swung down.

Title: EDM correction system for curved contours - uses vector monitoring for trailing electrode wire to maintain straight cut
Inventor: ULLMANN WERNER DR ING
IPC: B23H7/06
Filed: 1978-06-16
Abstract: The correction system for electro-discharge or electrochemical machining prevens cutting errors caused by trailing of the tensioned electrode wire. The corrector ensures that curved contours are cut to the specified geometry. Rotation of a vector associated with the curved contour of the work is monitored. If vector rotation exceeds a certain angle then the stretched wire electrode is pulled back in the already cut contour until the forces causing trailing vanish. The wire becomes straight and it is moved forward into cutting position and erosion resumed.

Title: Electrically-operated vehicle door locking system - incorporates parking switch contacts with drive motor to simplify wiring to manual switch
Inventor: BETSCH HELMUT
IPC: E05B77/48
Filed: 1979-02-09
Abstract: The electrically-operated door locking system for a vehicle uses an electric motor (10) which incorporates a double switch (20, 30) forming a partking switch. When a manually operated switch is in one position, its two contacts (12, 13) are connected to the negative side of the power supply. They are then connected by two wires (14, 15) to the double switch, with a path through its two contacts (21, 31) a diode (42) to the motor (10). When the manual switch is reversed, the positive connections allow current to flow in the opposite direction through the diode which then conducts so that the motor is operated. Wiring is simplified in this circuit. The motor contacts can also include a further path which keeps the diode from operating during changeover.
