Title: Ballistic thermonuclear warhead has narrow shaft - contg. lightweight firing piston with low kinetic energy
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: F42C19/08
Filed: 1976-03-02
Abstract: A ballistic fusion explosive head or thermonuclear weapon is described. The weapon head is fitted to a long shaft which contains a firing piston and is of min. calibre. From the initial firing zone of the compression chamber to the main charge there is only one ignition amplifier chain comprising two process compounds. In the compression chamber space a mixt. of deuterium and tritium is the initial gas charge, while the main charge space contains deuterium or ordinary hydrogen. One or other of these gas types is present in the ignition amplifier so that the ignition in the compression chamber is started by relatively small kinetic energy of the piston, that is both small piston calibre and low speed, i.e. it has a short shaft. By making the weapon of small calibre it can easily be fitted to a rocket, torpedo, bomb or mine.
Patent DE-2608812-A1 (DE)
Title: Automatic focussing for camera - is coupled to viewfinder and monitors contrast of image on retina of user
Inventor: FORBERICH HELMUT DIPL PHYS
IPC: G02B7/36
Filed: 1976-03-04
Abstract: The automatic focussing camera has the viewfinder optics in parallel to the main optics. A secondary optic system is used to monitor the image on the retina of the camera user and to determine the contrast of that image. A feedback control operates a servo motor (11) to adjust the focus of the lens for optimum sharpness, without any additional control. The system sets the focus on that part of the image which the camera user is looking at. This enables the camera to provide sharp images with a variable focal length lens, without having to compute depth of focus. The scanning of the retina can be most suitably performed with an infrared beam from e.g. LED.

Title: Pneumatically operated settling tank valve - has expanding shell on rigid carrier body with channels connected to pneumatic source
Inventor: GEBHARDT GUENTER
IPC: B03B5/24
Filed: 1976-09-14
Abstract: The pneumatic valve serves for controlling uplift and frequency of pneumatic impulses on pneumatically operated settling tanks. The aim of the design is to create a valve with small moving mass. The valve (13) is mounted in tube (14) connected to the settling tank containing the grains of minerals in a separating fluid. The valve consists of a rigid carrier body (13) fitted with a channel system (15) connected by pipe (21) to a compressed air source. The valve is held in central position within the tube by arms (18). The rigid body (13) is surrounded by an elastic shell (17). When pressure is applied via connection (21) the elastic shell inflates and comes to rest against the walls (19) of tube (15) closing completely passage of air to the settling tank. When according to the frequency of the control system the pressure in pipe (21) is cancelled, the air leaves the valve body and the shell returns to its original shape.

One side acts as a mould for a latex matching the rib dimensions and the channels between the ribs. The smooth upper surface of the latex is clad with a layer of a stretch woven tricot. This gives a laminated material with the latex giving the adhesion for the cladding layers with an elastic cross section in a notched or crenellated form. The fabric gives garment materialw ith properties for applications in thermo-therapeutics, hydro-therapeutics, skin treatment, electrolphysiological applications, remedial gymnastics, and support functions.
Patent DE-2700213-A1 (DE)
Title: Animal fur processing - by making cuts parallel to centre line in specified widths, lengths and sewing pattern (NL 8.7.77)
Inventor: REIMER AAERON
IPC: A41D5/00
Filed: 1977-01-05
Abstract: Dressed animal furs are processed by cutting on both sides of the back at a distance from the centre line two strips of equal width, amounting to half the width of the dorsal strip. Their length is chosen in such a way that the air structure remains uniform after the pairs of strips have been sewn together along the edges facing each other. Method reduces labour needed for conventional herringbone type of cutting and re-sewing. The material, wasted for the many sewn seams is also saved. The latter can in the case of mink amount to a saving of four pelts per fur coat. In the case of mink, the fur is cut into five strips (2-6). The strips (3-6) are of equal width but only half the width of the dorsal strip (2). The strip (2) extends from the tail end (9) to the cut (7) near the front legs, the strips (3,4) run from the tail end (9) further forward to the cut (10), and the strips (5,6) extend from the tail end (9) to the cut (11) near the head. The outer strips (15,16) are sewn to each other along the facing edges by a straight seam, followed by drawing a sinusoidal line. After wetting this line is stretched into the position where the straight seam was and the fur is fixed in this position and allowed to dry. Two strips of 4 mm width are cut at a distance of 2mm from the centre line of the dorsal strip (2). These are used at the junctions between strips (3,4) and (5,6).

Title: High speed multistate switching circuit for function generator - has Graetz diode bridges switched to current sources
Inventor: HAUER PETER
IPC: H03K6/04
Filed: 1977-05-18
Abstract: The high speed multi-state switching circuit transfers a signal at a selected input through to the output and is for use in a function generator for independently altering the leading and trailing edges of signals. In the three-state version of the circuit, two Graetz diode bridges are each switched (K1 etc.) by one diagonal to current sources (I1 etc.) connected to the voltage supply. Each bridge's other diagonal is connected between the shared output (K) and one of the two inputs (B1, B2). If a logic level of '1' is applied to B2 and a logic level of '0' to B1 then an output of '0' will appear if K1 and K2 are closed and K3 and K4 are open.
