Patent DE-2409359-A1 (DE)
Title: Resilient chin support for violin and viola - made of thermoplastics and of varying thickness
Inventor: HESSE GEORG
IPC: G10D3/18
Filed: 1974-02-27
Abstract: Resilient chin support for violins and violas is made of thermoplastic material. It has a curved shape, with a raised saddle, a trough and an outer rim, and is seated on the support to which are screwed retaining yokes. The central trough portion is thinner than the other portions so as to impart elasticity to the chin support. In use it is comparable to those made of wood, and is as economical to produce as those of "Duroplast" while being more light-weight and more agreeable to the skin. Although other forms are possible the main specification supports the modern recommended technique of holding the instrument as lightly as possible.

Title: Tar mist separation from coke oven gas - by ammonia liquor spraying using a venturi scrubber and separator in common reactor
Inventor: BAUM KURT DR ING
IPC: C10K1/12
Filed: 1974-07-30
Abstract: Tar mist left in coke oven gas after cooling and condensn. is removed in a venturi scrubber by sprayed ammonia liquor and a separator. The spray contains 4.2g/l ammonia has a temp. of 35 degrees C. and is sprayed at a press of 0.8 kg/cm2 from nozzles of 4.6 mm in dia. Entrained condensate droplets and coarse dust particles are removed by preliminary spraying with cold washing medium, followed by cooling with the same medium in a venturi scrubber. A swirl plate separator with a drop separator removes the washing medium from the gas. This greatly improves the efficiency of the process. The new design combines the execution of a greater number of process steps with a simplification of the whole operation.

Title: Tubes of unequal diameters with tapered ends - to produce welded joints with low thermal stresses
Inventor: STRIEBIG KARL-HEINZ DIPL ING
IPC: F16L13/04
Filed: 1974-09-12

The smaller tube is tapered outwards (3) at an identical taper angle such that it fits over the taper of the larger tube. An external seam weld (5) is then produced which, due to its position on the tapered tube section reduces the welding stresses set up.

Title: Video record player three-phase motor circuit - using adjustable capacitor to provide optimum capacity for motor run
Inventor: RICHTER GERD DIPL ING
IPC: H02K17/08
Filed: 1974-12-11
Abstract: The motor is connected to alternating voltage source in such manner that its third terminal is connected to one of the phase through a phase-shifting capacitor. In order to obtain true running of the motor, the capacitor capacitance is equal to the capacitance (Copt) obtained from a diagram showing the three motor currents (I1, I2, I3) as a function of capacitance (C) at rated voltage. The value (Copt) is determined by the point (5) in which the curve (I2) with the steepest positive gradient intersects the curve (13) with a negative gradient. Preferably the control diagram is adjustable to provide optimum capacity values.

Patent DE-2526335-A1 (DE)
Title: Reactor primary coolant ducts in second containment - with pressurised annular space to relieve primary ducts of stress
Inventor: GYOERY KALMAN
IPC: G21C13/02
Filed: 1975-06-12
Abstract: A method operating press. ducts which are surrounded by an outer, press-resistant pipe system, esp. for operating the water coolant ducts of a nuclear power plant, consists of filling the annular space between inner duct and outer pipe with a fluid medium (typically air) which is at the same press. as the fluid in the inner duct. The annular space pref. contains a porous, solid substance, through which the fluid medium flows. Where the double pipe-and-duct system provides a second containment for a reactor prim. circuit, the introduction of pressurised fluid into the annulus relieves the inner duct of press. and thus obviates risk of a burst. The provision of porous, solid material in the annulus ensures insulation of the inner duct without obscuring the outer pipe from visual inspection.

Title: Ejector for rapid uniform dispersal of tinsel - is used in naval warfare for generating radar confusing cloud
Inventor: DRTIL WALTER
IPC: F41B11/00
Filed: 1975-06-19
Abstract: The system for rapid and uniform distribution of a very large number of radar confusing defensive tinsel strips involves ejecting them in a cloud incident radar waves are either absorbed or reflected. The apparent target is rapidly built up on a ship or boat and the ejection rate of this material can be controlled. The cloud ejected can be adapted to suit given tactical cases. This ejection system is not held on the tip of the mast or other high structures. The small strips are held in a tightly packed form in a container and they are ejected by a compressed air pulse, preferably of high pressure so that at least one packet is thrown into the given area and opens there. The ejection energy can be supplied by a rapidly opening valve or by a safety valve. The packets of elements are fed into the ejector barrel from a magazine or drum.

Title: Machine for manufacturing e.g. thin walled bellows - has several dies mounted on turntable and built up from cylindrical parts
Inventor: SCHIKLENKOV VIKTOR KONSTANTINO
IPC: B21D15/10
Filed: 1975-08-07
Abstract: The machine has an infeed arrangement for the raw material and a removal arrangement for the finished parts, which work in cycle with a turntable.

Title: Electric switch with contact rocker bridge - has bridge fulcrum surface of part cylindrical or spherical shape with specified axial alignment
Inventor: JAEHNER WILFRIED
IPC: H01H1/20
Filed: 1975-09-26
Abstract: The rocker switch has a switching bridge having a fulcrum bearing, abutting a contact support in the switch broken condition. The bearing surface is arcuated, such as in the form of a part cylinder. The cylinder axis passes through the centre of gravity (S) of the rocker bridge (2). Alternately the bearing (14) forms a part of a ball whose centre is located in the centre of gravity of the rocker bridge. The abutting surface of the contact support (12) is flat. The design prevents any torque at the rocker bridge during contact making and safeguards proper switching even with arced contacts.

Title: Electron microscope electron source - with lanthanum hexaboride bead heated by current passage through rhenium or tantalum (alloy) wires
Inventor: RAMACHANDRAN KOVILVILA N
IPC: H01J37/065
Filed: 1975-11-26
Abstract: An electron source for electron microscopes includes a heater, consisting of a strip of rhenium, or tantalum, (alloy), and an electron emitter which is a small sphere of LaB6. The latter is attached to the surface of the strip in such a posn. that the passage of an electric current heats it up sufficiently for the emission of electrons from its surface. This electron source is much less fragile than one with a carbon heater. It combines good stability with a long service life.
