Title: Mounting assembly for circuit boards - has hooks which can engage rectangular holes in board and which are locked in place by insertable posts
Inventor: STRECKER HANS
IPC: H05K7/02
Filed: 1975-04-29
Abstract: The mounting assembly, for circuit boards and similar devices, consists of locking hooks (2, 3) that engage in elongated rectangular holes (4) in the board (5). Each hook is rectangular and has a projection (3) at one end and that slides beneath the board (i.e. behind the rectangular hole) when the board is moved in the direction of the longest axis of the hole.

Title: Semiconductor injection laser prodn. - by complete removal of substrate from epitaxial monocrystalline films reduces degradation
Inventor: SCHLOSSER EWALD DIPL PHYS
IPC: H01S5/323
Filed: 1975-07-02
Abstract: Prodn. of the laser is carried out by epitaxial deposition of a number of monocrystalline films, including a laser-active zone, on a monocrystalline substrate of the first conductivity type, these layers being partly of different conductivity type.

Title: Electric fuel injection circuit - has retard switch for fuel pump and thermal time switch for cold start valve
Inventor: TAUBE PETER
IPC: F02D41/06
Filed: 1975-07-11
Abstract: Circuit is designed to delay the switching off of the fuel pump should the air metering valve unintentionally close. The cold start valve has a thermal time limiting switch to prevent the engine from being flooded with excess fuel after abortive start attempts. The lead from the ignition switch contains a time delay switch which provides a response from the relay which is greater than the unintentional closure of the air volume dependent switch. A realy is in series with the cold start valve and thermal time switch. The retard switch is related to the length of the cold start valve working time. The thermal switch limits the combined length of the successive cold start attempts.

Title: Gadolinium iron alloy for thermomagnetic recording - with high sensitivity for use with gallium arsenide laser
Inventor: BOTSCHKAREV VLADIMIR FEDOROVIT
IPC: H01F10/13
Filed: 1975-07-28
Abstract: Carrier for thermo-magnetic recording has a substrate made of an electrically-insulating material, e.g. glass, coated with a working layer of iron-gadolinium strip with the direction of easy magnetisation perpendicular to the surface of the substrate.

Title: Mechanism raising and lowering venetian blind - initial movement is made with slats held open by cranks
Inventor: SCHLUEP RENE
IPC: E06B9/32
Filed: 1975-09-15
Abstract: When a Venetian blind is raised or lowered, the movement often starts with closing the slats, which are adjusted to their required aperture only at the end. This is sometimes inconvenient, esp. in public rooms, and the present mechanism's movement starts with opening the slats. In an embodiment the cords that tilt the slats are attached to the cranks (24, 25) which always point in opposite directions. When the drive reaches a stop, the slats are fully open, and the blind can be lowered without any further tilting of the slats. When the cord is pulled to raise the blind, the mechanism turns as far as the opposite stop. In the meanwhile, both cranks turn through a complete revolution, during which the slats fully close and fully open again.

Title: Electrode regulator for arc furnace - protects transformer against overloading by setting working point in specified way
Inventor: SCHUBERT MANFRED
IPC: H05B7/109
Filed: 1975-10-04
Abstract: The electrode regulator, for an arc furnace, reduces processing times at voltages below the primary voltage and prevents overloading the transformer at voltages above the primary voltage. Regulation takes place from a given staring point in steps according to Z = constant, P = constant and S = f(Ua), where as is a real positive number. For working points that differ from cos phi = 0.707, a working point is chosen according to a given function and depending on the instantaneous primary voltage. When cos phi = 0.707 the original working point is reset by selecting a transformer stage corresponding to the magnitude of the difference.

Title: Chocolate melt tempering process - in thermostatted agitator tank with chilled side stream recycled by worm conveyor
Inventor: BUYLTON-DOMGRAFF RALPH VAN DER
IPC: A23G1/18
Filed: 1976-01-27
Abstract: In a heat-treatment of molten chocolate mass, the melt is gently cooled in as stirring motion to 33-34.5 degrees C. A side stream is branched off for a certain time, cooled rapidly to under 33 degrees C and added to the melt in the mixer-agitator tank. The temp. in the tank is kept at a constant 33-34.5 degrees C. This produces large quantities of tempered chocolate mass at little power consumption. Only simple appts, is needed and the formation of coarse crystals is eliminated.

Title: Reciprocating to rotary movement conversion mechanism - has spindle with threads of opposite pitch driving nuts with ratchets
Inventor: GEHRA LUDWIG
IPC: F16H25/22
Filed: 1976-02-23
Abstract: The mechanism converts reciprocating motion into rotary motion in the same direction, having a screwed spindle with two threaded sections of opposite pitch, working in nuts each acting via a ratchet mechanism on a gear ring. The two nuts transmit movement to the ring both on the forward and the return stroke of the spindle. The ratchets lock one nut into engagement with the latter on the forward stroke, while allowing the other to freewheel on it. Where it is desired to convert strong thrust forces into rotary movement, a number of spindles can be used, with the nuts forming part of planetary pinions on a common thrust stirrup.

Title: Deep freeze shelf with open display front - has deep frozen air curtain stopped during defrosting of evaporator
Inventor: SCHUBERT HEINZ
IPC: A47F3/04
Filed: 1976-06-26
Abstract: The deep freeze wall shelf has open front wall, covered with a deep freeze air curtain generated by a lower air curtain inlet and outlet at the upper end. This inlet and outlet are connected by a channel which accommodates an evaporator and a blower. The shelves can be stacked and the buyer is able to see goods on display.
