Title: Pipes continuously insulated in production line - by fitting segments around pipe as it advances
Inventor: OPPERMANN WILLI
IPC: B29C48/09
Filed: 1973-10-29
Abstract: A method of applying insulation continuously to pipes in a production line, where the pipes are heated, primed, and extruded, consists of fitting preformed segments of insulation around the pipe as it advances.

Title: Surface heating for buildings and floor spaces - uses pipes with flat section terminating in round section
Inventor: ENGEL THOMAS PAUL
IPC: F28F21/08
Filed: 1973-11-29
Abstract: Flat pipes are laid in floors or walls of buildings so as to present the greatest possible surface area, and the ends are deformed to a round section to make connection to piping possible.

Title: Heat pump system for heating buildings - has hot air Carnot cycle engine driving reverse Carnot cycle pump
Inventor: LEEDER WALTER
IPC: F25B29/00
Filed: 1973-12-05
Abstract: Heat pump system for heating buildings and industrial appts. uses two cyclic processes. The first cycle is used in a hot air engine working on the Carnot cycle. The mechanical energy produced is used in the second cycle, running in the reversed direction and possibly also in a Carnot cycle, to bring heat taken from a heat reservoir at lower temperature up to a higher temperature level. Preferably both cycles occur in a common, pressure-tight vessel, and the driven side is separated from the driving side by a piston, a diaphragm, or a gas-permeable, sieve-like heat-impermeable unit similar to the conventional regenerator of a Stirling engine. Electrical energy, is not required.

Title: Loading mechanism and transporter for heavy components - has load carrier mounted on telescopic support structure
Inventor: HENFREY KENNETH MARDEN
IPC: B66F9/12
Filed: 1974-07-09
Abstract: This loading and transporting arrangement is used especially on loading components int a treatment plant, for example in loading components into the pressure vessel of a sterilization plant. In the transporting position the load supporting trolley carries the full weight of the load on a frame which is supported on all corners. On loading into the pressure vessel of a sterilization plant the load carrying platform overhangs and enters the presure vessel together with the load. The carriage in this case is in the retracted position. The load carrying trolley has vertical legs and swivelling wheels. The front wheels are supported by vertical members connected to a locking device on the side rail of the trolley platform. When the load on the trolley is going to be pushed into the pressure vessel then the lock is released and the vertical members are pushed towards the rear wheel supports and the platform rails overhang and the load enters the pressure vessel.

Title: Oscillating fork for balancing of crank shaft - has hydrostatically linked pistons to maintain contact with cams
Inventor: PAPEZ STANISLAV DIPL ING
IPC: F16F15/26
Filed: 1974-09-12
Abstract: A crank shaft is dynamically balanced by a forked lever (11) which oscillates about a pivot (15) that is parallel with the crank shaft axis. The cams (9, 10) of the crank shaft are located between two sets of fork prongs (12, 13). Contact between fork and cams is made by opposite pistons (21) in the prongs. The pistons are hydrostatically connected by internal holes (17, 19). An integral pressurized oil reservoir, linked to the system maintains a constant piston pressure on the cam faces, thus even at high shaft speeds, the balancing mechanism does not create a noise problem.

Title: Tig welding source - has antiparallel thyristors in primary transformer circuit fired by feedback signals from secondary half waves
Inventor: JUNG WERNER
IPC: B23K9/10
Filed: 1975-02-06
Abstract: A welding current source for TIG (tungsten-inert gas) welding has in the primary circuit of the welding transformer two thyristors which are connected in antiparallel and are separately controlled by feedback signals originating from the secondary (welding current) circuit of the transformer. The output voltage of a transductor or a current transformer in the secondary circuit is half-wave rectified in one branch in the positive direction and in the other branch in the negative direction. Both branch signals are used to control the thyristors through a lamp and a photodiode. This prevents the detrimental effect of the d.c. component during the a.c. welding of light metals which is caused by the unsymmetry of the a.c. voltage. The result is reflected in better ignition properties and better arc stability.
Patent DE-2507717-A1 (DE)
Title: Tie ribbon dispatching channel on packing machine - has hinged angle plates operated by tension ropes
Inventor: BUCKERT GUSTAV
IPC: B65B13/06
Filed: 1975-02-22

Perpendicular arms (17) attached to each channel half have location holes (16) near their free end, for opening ropes. Between each pair of channel sections fixed guide holes (13, 14) also locate the operating rope (10). when the rope is under tension, the arms (17) are forced towards the channel axis, thus closing the channel. Opposite acting ropes or springs are used to open the channel for the release of tie ribbons.

Title: Measured voltage convertor esp for sea water oxygen measurement - uses phase angle between two AC voltage vectors
Inventor: KROEBEL WERNER PROF DR
IPC: G01R17/04
Filed: 1975-03-12
Abstract: The converter converts measured d.C. voltages into the phase angle variation of two a.c. voltages. The d.c. voltage to be measured is pref. amplified, compared with the rectified a.c. voltage amplitude produced by an oscillator and regulated so that the d.c. voltage coincides with the peak a.c. voltage amplitude. From the difference between the a.c. voltage corresponding to the d.c. voltage and selected optimum a.c. voltage an algebraic variable vector is formed. This is added with the two partial components of the oscillator a.c. voltage after displacement by 90 deg. to produce two variable-phase algebraic vectors whose phase angle relative to each other represents the measured d.c. voltage.

Patent DE-2533266-A1 (DE)
Title: Milling cutter with unequally spaced teeth - has radial adjustment of teeth to avoid vibration due to resonance
Inventor: REINHARDT HERMANN
IPC: B23C5/00
Filed: 1975-07-25
Abstract: The cutter body has a number of cutting teeth fixed by wedges secured with screws having threads of opposite hand at each end. The cutting teeth are unequally spaced around the circumference of the cutter body in order to minimise the possibility of creating a resonant vibration equal to the rotational speed multiplied by the number of teeth. This effect of resonance avoidance is enhanced by adjusting the radial projection of each tooth by using pins of different diameters. The number and position of teeth which actually cut into the workpiece can thus be varied and so avoid undesirable resonances.
