Title: Analogue multiplier circuit system - produces voltage product output using FET bridge network to keep output independent of temp. changes
Inventor: SAILER HEINRICH DIPL ING
IPC: G06G7/163
Filed: 1975-10-16
Abstract: The circuit has a resistance bridge (R1, R2, R3) with one leg containing a FET (F1). An output voltage over the bridge is taken to a linear amplifier (OP1) to produce the output which is dependent on an input voltage to the FETs (UST) and to the input to the bridge (UE). The output voltage is also temperature dependent. This problem is overcome by incorporating similar FET (F1, F2) in two opposing legs of the bridge, together with suitable supply resistors (R4, R6). A further refinement is the connection of a linear amplifier supply dependent voltage to the second transistor (F2) and an analogue addition circuit to sum this voltage with the second variable inputs (UST) before application to the first transistor. A more developed version using input operational amplifiers (OP2, OP3) is also described.

Title: Direct conversion of thermal into electrical energy - exploits kinetic energy of charged particles derived from thermal excitations at heated surface
Inventor: GIESE PETER DIPL ING
IPC: H01J45/00
Filed: 1975-11-29
Abstract: The process converts heat directly into electrical energy. Charged particles receive thermal energy from a warm surface via thermal excitations. They are then converted in an additional alternating charge pressure, in a vacuum. Permeable capture and braking electrodes near capacitive charge surfaces are subjected to an alternating voltage. The additional alternating charge pressure can be collected as a (capacitive) e.m.F. either directly from the primary capacitive surfaces themselves, or indirectly from a secondary surface suitably capacitively coupled.
Patent DE-2555220-A1 (DE)
Title: Gas purificn. by addn. of absorbent - in series of stages with sepn. and recycling of absorbent after each stage
Inventor: HOELTER HEINZ
IPC: B01D53/60
Filed: 1975-12-09
Abstract: A gas, at >=120 degrees C, requiring purificn. and to which can be added an oxidising agent, e.g. H2O2 or potassium permanganate, is passed through a series of tubes where it is mixed with an adsorption agent, e.g. slake lime, calcium carbonate, iron oxide, amorphous silica, porous perlite or filter carbon, having a granulometry pref. 50 mu. Each mixing tube is followed by a separator which removes the absorbant from the gas stream and recycles it counter-currently to the gas flow. Absorbant is introduced into each mixing tube through >=1 nozzle pointing downstream, each nozzle followed by a conical flow obstacle with its pointed end facing the nozzle, then a truncated converging section of the mixing tube reducing the flow area for the gas. Absorbant recycled counter-currently is removed from the separator after the first stage mixing tube, par of the absorbant is rejected and the rest is sent back to enter the final stage mixing tube, fresh make-up absorbant being added before it enters the mixing tube. Alternatively the recycled part of the absorbant is introduced into the penultimate mixing tube, with the fresh make-up absorbant being fed into the final mixing tube and the absorbant recovered from the separators after these stages is mixed before passing to the next mixing tube upstream. Rejected absorbant can be rid of harmful prods. by converting them to calcium sulphate using air and lime wash or by heating it in a Claus furnace after which it can be re-used. Process is used for purificn. of flue gases contg. SO2 and NOx. The absorbant need not be expensive and can be re-used several times with the process still giving a very high purificn. effect. The reaction is very rapid so that the installation is small and there is low energy usage.
Patent DE-2556727-A1 (DE)
Inventor: HAUPT WILHELM
IPC: B62B13/06
Filed: 1975-12-17
Abstract: This skibob is driven while standing. It comprises a rigid frame (1, 2) and a control ski (8) which can be pivoted transversely with respect to the direction of travel and is mounted in the frame (1, 2). Two stand-on skis (15, 16) are likewise mounted on the frame (1, 2) but with respect thereto and to each other are forcibly guided in parallel and alternately changeable in height. This forcible guiding in parallel and ability to change the height of the two stand-on skis (15, 16) relative to one another provides an automatic adaptation to the terrain and use of the edges both when travelling obliquely to a slope and when the frame is tilted out of the vertical position, for example when travelling around curves, and, as a result, the said skibob, as a consequence of the mode of travel being similar to conventional skiing, is also suitable as an apparatus for teaching skiing. <IMAGE>

Title: Stabilised magnet coils superconductor wiring - has reinforcing elements preventing superconducting wires from bending under applied forces
Inventor: FILLUNGER HARALD DIPL ING
IPC: H01B12/10
Filed: 1976-01-26
Abstract: Reinforcing elements (4, 7) prevent the superconducting wires from bending in the expected direction during production and further processing. This ensures that they can be bent only to a degree which does not reduce their superconducting properties during operation. The whole wiring system is held in clamps (8, 9) which surround the reinforcing elements (4, 7). The intermediate elements (7) are 'U' shaped and can protect the superconducting wiring from spreading along the crack between the outermost elements (8, 9).
Patent DE-2609172-A1 (DE)
Title: Variable effect handbrake lever - has one directional stops for rigid linkage in release direction
Inventor: SCHROETER HANS O
IPC: B60T7/10
Filed: 1976-03-05
Abstract: The handbrake rod (6) is linked to the handbrake lever (1) by two link arms (8, 9) which effectively alter the mechanical advantage of the handbrake lever as it is pulled up, by reducing the effective spacing of the linkage from the lever pivot. The two levers are joined by a spring (13) and two interlocking stops (12) which allow angular setting in one direction only. When the tension is released the two levers are set in a rigid line to enable the lever to push back on the brake rod and release the brake. The system provides a strong brake force, after the brake play has been taken up. The release force acts directly on the brake linkage and thus eliminates the need for any return springs to pull off the brakes, which in turn reduces the force required to pull up the brakes.
