Title: Adjustable ring-shaped spring clamp - for holding pipe ends together for welding, avoids uneven stressing and distortion
Inventor: ZOZ JOCHEN REINHOLD
IPC: B23K37/053
Filed: 1972-11-02
Abstract: The ring has a rectangular cross section which tapers gradually from the thickest portion at the top to the thinnest portion at the bottom where it is split. The split ends have eye-holes in which are bolts which may be drawn together or sepd. by a double-acting pneumatic cylinder. The ring is made of Al or plastics with a metal insert, and must have enough spring in the unloaded condition to allow it to be placed by hand over the end of the first pipe. Hydraulically operated radial stops round the ring are used to posn. the two pipes and then withdrawn so that one can be pushed up against the other, in which posn. the clamping mechanism is operated to hold them firmly together. Spot welds can then be made through apertures at intervals round the ring. The clamp is light to handle and distributes the stresses evenly round the pipes being held.

Patent DE-2351147-A1 (DE)
Title: Radio receiver with phase control loop - has phase comparator delivering series of pulses to loop
Inventor: HECKMANN HEINER
IPC: H03D3/24
Filed: 1973-10-11
Abstract: The pulses with constant spacing are delivered to a control voltage. Their width decreases as the signal-to-noise ratio also decreases. This pulse train is applied to an integrator followed by a Schmitt trigger, whose response voltage can be set to the required signal-to-noise ratio. The Schmitt trigger output controls a switch by which the l.f. amplifier is switched off when the above ratio falls below the response threshold. The Schmitt trigger consists of a differential amplifier, and the adjustable response voltage is derived from the phase control loop operational voltage, and applied to the amplifier second input.

Title: Measurement method for finely divided material - material is fluidised to form uniformly condensed heap in chamber
Inventor: FASSAUER ARTHUR LEO
IPC: G01F11/00
Filed: 1974-04-30
Abstract: The material to be accurately measured is fluidised by small vibrations, thus reducing its density. The material is then brought to a measurement chamber where it forms a uniformly condensed heap of a fixed geometrical shape. A volume containing a specified quantity of material flows by gravity from the heap, and is thus measured. The fluidised material passes through a perforated plate into a concial measurement funnel. It is carefully stirred near the funnel conical wall, so that it is conveyed to the measurement area through the whole bottom area of the funnel. The amounts that can be accurately measured ranges widely.

Title: Transmission system has clear-back signal marked by pulses - and uses pulses in audio frequency and inimitable by human voice
Inventor: DIRR JOSEF ING GRAD
IPC: H04Q1/446
Filed: 1974-09-07
Abstract: The transmission system, for telecommunications, has the clear-back signal marked by several or numerous pulse groups (e.g. telegraphic code, data code) on the audio frequency baseband. The pulses or pulse groups are arranged to have a minimum length such that they cannot be imitated by the human voice. The pulse lengths and gaps are equal, and the pulse repetition frequency lies above the human range (3000Hz). The pulses are transmitted without using a central element. The pulses are evaluated by a memory and/or counter.

Title: Helicopter rotor attached parachute - has two part rocket assisted container to avoid twisting of lines due to rotation
Inventor: KOPPEN WERNER
IPC: B64D17/80
Filed: 1975-01-29
Abstract: The equipment is in a two-part container.

Title: Device for measuring gas constituent concentrations - uses hand-operated spring bellows pump and impregnated indicator paper
Inventor: BLUNCK OTTO DIPL PHYS DR
IPC: G01N31/22
Filed: 1975-02-19
Abstract: The device consists of a simple spring bellows hand operated pump, containing a fixed volume when fully extended, between an upper and lower plate (9, 10). A gas inlet (11) is provided through the top plate and a gas outlet (13) is provided with a valve (12) in the bottom plate. The inlet duct (11) admits the gas through a treated paper membrane (4) mounted in a cartridge (1).
