Title: Two-pin socket and plug connector - with protected access holes uses internal sliding plate with wedged area on crossbars for size reduction
Inventor: KRUEGER FRITZ
IPC: H01R13/453
Filed: 1974-07-18
Abstract: The multi-pin socket/plug connector has in its housing recess a sliding plate held in place by spring tension. The sliding plate has crossbars with wedged areas which cover up the pin accepting holes with the plate in its end position. The two cross-bars (24) of the sliding plate (14) are connected by a single longitudinal bar (12). One crossbar is provided with a swivel axis (36). The sliding plate (14) in top view may have U-shape, E-shape or meander shape. The swivel axis of the sliding plate is obtained by two pivots (36) which are attached to opposite sides of one crossbar (14). They are positioned in two oblong recesses (19) in the housing flange. A reduction in width and easy manufacture are the result.

Title: Locking device for gyroscope gimbals - prevents damage to bearings when subjected to large inertia forces
Inventor: RAPP DIETER ING GRAD
IPC: B64G1/28
Filed: 1974-07-26
Abstract: The gyroscope rotates about the axis in bearings mounted in the frame. The frame can pivot about an axis in bearings attached to the circular frame (7) which, in turn, can pivot about the axis (8) in bearings attached to the outer frame (1). The gyroscope is intended for the control of space craft and when in orbit each frame is free to rotate about its own axis. During the launch of the spacecraft the frames are locked by bolts (22) which are forced by electro-magnets into holes (26). This locking of the frames prevents damage to the bearings by the large inertia forces generated during launching.

Title: Thermally actuated electric cct. fuse - has two thin conductive strips on heat resistant insulating flexible film and resilient contact
Inventor: OKAZAKI TASUKU
IPC: H01H37/76
Filed: 1974-12-04
Abstract: The thermally actuated fuse is formed by two thin, conductive strips deposited on a heat resistant, insulating and flexible film, and strips being located in a housing at the film end. an elastic contact is pressed against the strips by an element of non-conductive resin of specified melting point. The melting on the resin releases the contact and this interrupts the protected circuit. Preferably a coiled spring is arranged between the rear of the resin block and the housing wall for effecting a close contact between the conductive strips and the block contact. A coiled spring may be also provided between the contact and the film, which permits the separation of the contact rear side and the housing inner wall.

Title: Stretching a tow of polyester filaments - through feed and draw rollers with controlled arcs of contact
Inventor: KOSCHINEK GUENTER DIPL ING
IPC: D02J1/22
Filed: 1975-08-02
Abstract: Tows of polyester threads, esp. of PET are stretched between a set of cylinders feeding of the inlet and a set of drafting cylinders. At least the inlet set comprises cylinders arranged in two horizontal planes one above the other between which the two, whilst heated, follows a meandering path up and down. The last roller of the inlet set is on the higher level and is heated to 40 to 70 degrees C, and forms a stretching point. From the last inlet cylinder, the two runs downwards at an angle of -30 degrees to +60 degrees to the vertical, to a draw cylinder leading into the drafting system. This cylinder can be displaced transversely to its axis and forms a second stretching point. The last cylinder but one of the inlet set (on the lower level) is partially immersed in a stretching bath maintained at 40 to 65 degrees C through which the two is run. Even with a very high density at high speed, the characteristics of the threads in the stretched tow are as homogeneous as is possible. The breakage of individual filaments during stretching, and deeper dyed places indicative of lack of uniformity are reduced to the absolute minimum.

Title: Cups prepd. from expansible thermoplasts - by extrusion blow moulding, with formation of reinforced opening by simultaneous folding over and compression
Inventor: ROBERG PAUL DR ING
IPC: B29C49/04
Filed: 1975-10-06
Abstract: Hollow plastic bodies, e.g., cups, are produced by extrusion/blow moulding, and have a reinforced opening formed by folding-over the wall in the blow moulding machine. During the mfr. of the hollow body from expansible thermoplastic matl., the expanded structure of this matl. in the region of its opening is densified by folding-over with simultaneous compression. This is effected so that the treated structure has >=1.5 times the density of the expanded matl. in the wall of the body. After folding has been effected, and the wall has been sepd. from the blow moulding tool, the part of the tool that formed the opening tangentially touches the inner face of the wall of the hollow body. Gives mechanically stable hollow bodies using a min. of thermoplastic matl. The bodies have good thermal insulation properties. When the hollow bodies consist of cups, these can be used for dispensing hot drinks, and for storing ice cream.

Title: Portable rye bread baking oven - with firebrick base plate, cowl and cover with window and thermometer
Inventor: KROHE ALFRED
IPC: F24C15/16
Filed: 1975-12-02
Abstract: The oven parts include a bottom plate with a groove into which a hood can be fitted. The open inclined end of the hood is closed by a cover with an observation window, a thermometer and a channel with a stopper which can be filled with water. Rye bread cannot be baked in a domestic oven with sheet metal lining because it does not provide the very slowly dropping temp. from a heat storing lining which is needed for good rye bread. The new oven can be inserted and bakes excellent rye bread.

Title: Integrated circuit semiconductor diodes - are used in logic circuits and have plastics housings with interspaces filled with casting resin as insulation
Inventor: HOFMANN HEINZ
IPC: H01L25/07

Abstract: An integrated circuit for a PCB uses a combination of components consisting of commercially available semiconduct diodes. It is suitable for high density packing as is required in logic circuits. The housing (g) is made from plastics and contains a number of diodes (D). The leads (Z) to the diodes are fed through the base of the housing and are separated by the minimum distance. The remaining space in the housing after insertion of the diodes is filled with insulated matter such as casting resin. Basically the dimensions of the housing will be a multiple of the layout dimensions of the printed circuit board. This means that several of these potted modules can be mounted next to each other or behind one another on the PCB.

Title: Vehicle head lamp monitoring circuit - has photocell and reference signals fed to comparator with logic control to operate warning device
Inventor: MEHLITZ DIETER DIPL ING
IPC: B60Q1/26
Filed: 1976-08-19
Abstract: The vehicle lighting circuit is fitted with a photocell to monitor the outside illumination and operate a warning if the lights are not switched on in poor visibility.
