Title: Spot welding tongs using rigid clamping arms - esp. for welding control rod guide tubes in nuclear reactors
Inventor: BEZOLD HELMUT
IPC: B23K11/31
Filed: 1976-03-11
Abstract: Spot welding tongs employed for joining workpieces which are not readily accessible, such as control rod guide tubes for nuclear reactor fuel elements, where the tubes are to be welded to fixing straps on spacer grids. The tongs consist of two coaxial tubes, one sliding inside the other, and each tube carries the welding current to an electrode. One electrode is mounted radially on the end of each tube, and the axial movement of the tubes is used to clamp the workpieces between the two electrodes. A conventional mechanical design is pref. employed to prevent the two coaxial tubes from rotating w.r.t. each other; and the electrode arms may be mounted tangentially on the tubes. In conventional spot welding tongs, the electrode carrier arms beng outwards when clamping pressure is applied so that the workpiecs are not correctly clamped between the electrodes; the result is faulty welds and malalignment of the workpieces. The invention eliminates such problems.

Title: Recovery of sulphur from gases contg. sulphur cpds. - by treating gas with polybasic organic acid
Inventor: GERMERDONK ROLF DIPL ING DR
IPC: B01D53/52
Filed: 1976-04-21
Abstract: Hydrogen sulphide is removed from a gas by treating it with an aq. soln. of a polybasic organic acid having a dissociation constant of 10-2 - 10-5, the soln. being buffered with a base. The molar ratio between H2S and SO2 in the gas is >=2:1 and it is injected into the soln. which is at pH 2-6 (3.3-3.9), at 10-100 degrees C forming solid sulphur which is removed by a current of the soln. from the reaction chamber. Gas contg. SO2 and having the soln. is heated to 700-1000 degrees C to transform S-contg. cpds. into SO2, and the gas is recycled. The rest of gas leaving the soln. is treated with a second absorption step with the soln. having the reaction chamber to remove the last traces of S. The process enables gas mixtures richer in H2S than cleavable by the Claus process to be purged of sulphurous gases.

Title: Automatic fuel flow control system for carburettor - uses electronic idling stage control for economical fuel supply
Inventor: HASENFUSS ROBERT
IPC: F02M3/045
Filed: 1976-11-20
Abstract: The control system is used for automatic connecting and disconnecting of the fuel supply for the carburettor idling system. This arrangement is used in diesel and petrol engines with injection systems. The fuel saving feature of these engines in which no fuel is supplied to the engine at certain speeds is extended also to engines provided with carburettors. When the carburettor is in its idling position and the engine rotating speed is higher than the idling speed then the fuel flow nozzle supplies the engine with fuel. Arrangements are provided to stop fuel flow to the engine until the accelerator is actuated or when the engine minimum is reduced. The system dependent on the carburettor idling position can have electrical switches or electronic actuation. Alternatively the air quantity drawn in by the engine can be used for operation. The system whose operation depends on the engine speeds can be controlled e.g. by the dynamo.
