Title: Trolley device to assist laying heavy tiles - has gripping clamps and foot pedal operated tile release mechanism
Inventor: STRATEN KORNELIS VAN
IPC: E01C23/12
Filed: 1976-06-29
Abstract: The device enables a footpath or pavement composed of heavy tiles to be laid by simple movements. It comprises a double-loop handle (1) attached to a pair of wheels (6) to form a small trolley. The wheel axle is supported on a bracket with lever arms (15) supporting at their outer ends a pair of clamps. (21). The trolley is pushed forward to the edge of the tile (31) most recently laid whilst holding the next tile (30) in an almost vertical position. The tile is lowered into the appropriate position on the ground, abutted to its neighbour and subsequently released by the action of the foot-pedal (26). The clamps are adjustable for different tile thicknesses and the jaws are equipped with plastics or rubber facings to prevent chipping.

Title: Prodn. of concrete with dust-forming additive - by preliminarily moistening additive and admixing it at building site
Inventor: MARTIENSSEN EKKEHARD
IPC: C04B40/06
Filed: 1976-06-29
Abstract: Prodn. of concrete using, apart from the main component, >=1 additive showing dusting tendency, is improved by moistening the dusty additive, or slurrying and transporting it in tightly closed containers to the building site, when it is mixed with the other components and water. Some of the other components can be admixed to the dusty additive before moistening the latter. Wastes or inferior materials showing dusting tendency can be utilised without health hazard and environment contamination. The method is esp. suitable for the prodn. of heat-insulating concrete, refractory concrete, acid-resistant water-glass concrete, etc.
Patent DE-2632225-A1 (DE)
Title: Gold diffusion in semiconductor devices - after doped zones are reduced to specified surface concn. for better reproducibility
Inventor: RAITHEL KURT DR
IPC: H01L21/306
Filed: 1976-07-16
Abstract: In semiconductor device mfr. zones of different type of conduction are produced by the diffusion of dopants until one of the outer zones has a surface concentration of >1020 atoms/cm3; gold atoms are finally diffused in it as recombination centres. Prior to the gold diffusion, the outer zone concerned is removed for enough to reduce the surface concentration to 2.1020 atoms/cm3. Diffusion of gold in the semiconductor substrate is thus more reproducible. The adjustment of the temp. during the gold diffusion, otherwise necessitated by the variable getter action as a function of the phosphorus, is not required any more.
Patent DE-2633296-A1 (DE)
Title: Analogue operational amplifier comparator - uses output voltage when input is shorted to charge capacitor for offset voltage compensation
Inventor: GASTEIGER RICHARD ING
IPC: H03F3/45
Filed: 1976-07-23
Abstract: The offset voltage compensator, for an analogue comparator comprising an operational amplifier, also takes into account the temp. dependence of the offset voltage. The voltage present at the operational amplifier's (V1) output when its input is short circuited is used to charge a capacitor (C). The capacitor is connected via a resistor (R8) to that input (+) of the amplifier that permits the capacitor's voltage to compensate the offset voltage. The capacitor is charged by closing a switch (S2), which also simultaneously short circuits the amplifier inputs (+.-).

Title: Purification of gas from pressurised coal gasification - by stagewise cooling in heat exchangers with purified gas and molecular sieve adsorption
Inventor: HEYN KLAUS DIPL PHYS DR
IPC: C10K1/04
Filed: 1977-01-13
Abstract: The gasification of solid fuel under pressure in a fixed-bed reactor is followed by a heat exchanger in which the crude gas is cooled to 200 degrees C by indirect heat exchange with the purified gas. The crude gas loses thereby a part of its entrained tar and dust and is passed to final detarring, dedusting and desulphurisation stages. Method eliminates the considerable evaporation losses when crude gas under pressure is treated in scrubber coolers. The tar/dust mixt. obtd. is easily processed and use of large settling basins are obviated.

Title: Ring spinning stop sequence - operates the spindle ring while ring is at rest to prevent yarn tangles
Inventor: IGEL WOLFGANG DIPL ING
IPC: D01H1/32
Filed: 1977-05-09
Abstract: Process to stop a ring spinning machine, fitted with pneumatic bearings, where an air cushion is formed by automatic suction into the gap between the spinning ring and the outer bearing in the ring rail, starts with a reduction in the spindle speed so that the spinning ring does not overtake the spindle and no more air is drawn in so that the spinning ring stops. The spindle speed is then increased until it reaches a value where the yarn cannot tangle during underwinding, and the spinning ring stays static. The spindle is then brought to an abrupt halt. Process ensures that the yarn does not tangle while the operating components are de-synchronised to give an orderly spinning off.

Title: High temp. gas cooled reactor in concrete vessel - has primary circuit components in separate concrete vessels suspended below
Inventor: MITTERBACHER PAUL DIPL ING
IPC: G21C13/00
Filed: 1977-05-18
Abstract: A nuclear power plant comprises a gas-cooled high-temp. reactor with block-shaped or spherical fuel elements. The reactor itself is housed in a pressure vessel contg. prestressed concrete, while other components of th e high-temp. gas circuit such as blowers are housed in separate prestressed concrete pressure vessels below the reactor pressure vessel and suspended from it. The reactor pressure vessel itself rests on the supporting structure. The hot gas ducts are vertical and follow the shortest path between the component pressure vessels and the main reactor pressure vessel. More specifically, they are coaxial ducts with a dividing joint in the plane between the main and subsidiary pressure vessels. A considerable reduction in the size of pressure vessel by comparison with integral construction is achieved. Short gas lines are obtd. by the direct connection between the components in the subsidiary vessels and the reactor in the main vessel.

Title: High speed roller with ball bearings races - has thin oblique inner races supported on bolt by elastic rings which set clearance
Inventor: MAYER ERNST DIPL ING DR
IPC: F16C13/00
Filed: 1977-07-01
Abstract: The high-speed roller runs in ball bearings, the rotary outer face being supported by one or more rows of balls on a bolt. The inner races(4) for the balls(2) are thin oblique shoulders, pref. drawn sheet-metal rings, and are mounted on the bolt(3) with elastic rubber or plastic rings(5) in between. This prevents direct contact between the inner races and the bolt, and spring-loads the races against the balls, giving the necessary amount of bearing clearance. The inner races can be of S-section, and the elastic rings circular, typically conventional O-rings. These latter can bear against cone faces on the bolt and on washers fixed to the bolt.
Patent DE-2733694-A1 (DE)
Title: Infusion metering appliance - with count pulses for drip sensor and decoder for adjustment of closure element opening
Inventor: HIRSCHMANN JOSEF
IPC: A61M5/168
Filed: 1977-07-26
Abstract: An infusion metering appliance has a closure element (rotary magnet) with the amt. of opening stroke controlled by a digital/analog converter which is fed by an UP/DOWN counter. A timing pulse generator produces two pulse trains, the second with a higher frequency. The first trains opens the closure element and releases another counter for the pulses of the second train; it is stopped by an output signal from a drip sensor which also shuts off the closure element. A decoder after this counter actuates the UP/DOWN counter in case of discrepancies of the counter from a setting and increases or reduces the opening stroke of the closure element. This results in a very exact metering of the infusion rate and its maintenance. It operates with a high functional reliability so that faults cannot endanger a patient. All defects are monitored by alarm signals or shut-down.
