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: 1975-05-30
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: Easy fastening for drawers and guide rails - has shaped arms on rail engaging in fixed and resilient fittings (OE150576)
Inventor: GRASS ALFRED
IPC: A47B88/04
Filed: 1975-09-01
Abstract: The drawer is provided with guide rail (6) which has arms running parallel in the longitudinal direction to the side wall of the drawer wherein one arm (12) of the rail engages in a first groove (11) of the cavity section of the drawer side wall whilst another arm of the rail can be pressed in at right angles behind a resilient lip (15) of a second groove (10).

Title: Plastics insulated telecommunication cable with colour markings - has cavities filled with waterproofing, non-hardening hydrocarbons e.g. petroleum jelly
Inventor: ANDERKA HEINZ-JOERG ING GRAD
IPC: H01B7/285
Filed: 1975-10-10
Abstract: The capacity couplings inside the cable are time-independent. The cable is conditioned after its mfr. but before the rectification of the couplings. The cable is heat-tempered by heating the ready-stranded, filled, and sheathed, cable to age it so that the capacity differentials are first stabilised and then equalised. Alternatively, the ageing/stabilising process may be carried out before the cables is sheated. Ageing may be initiated or speeded by adding suitable adjuvants to the water-proofing medium or to the insulating coating. The surface of each conductor may be colour-marked at regular intervals. The colour may be based on a polyolefine or some other inert polymer.

Title: Protection against ballistic missiles for military equipment - has active armour with rotating plates absorbing missile kinetic energy
Inventor: HEYM ULLRICH DIPL ING
IPC: F41H5/18
Filed: 1977-01-04
Abstract: The protection arrangement against ballistic missiles utilises energy of rotating rigid bodies. This rotating element can be made from armoured steel and is used preferably for protection of military equipment. The armour consists of rigid bodies such as round plates which rotate at high speeds. A projectile meeting such a disc acts as shear pin and it must stop the whole rotating mass in order to ensure penetration. The kinetic energy of projectile is balanced by the kinetic energy of the disc. The rotating movement of the armouring induces the projectile to penetrate more material than that provided by the thickness of the armouring. The protection can be further increased by increasing the rotating speed without increasing the weight.

Title: Safety control unit for stamping press - has two signal processors to prevent operation of press should control system or operational errors occur
Inventor: GUSTAVSSON ALF GOESTA
IPC: B21D55/00
Filed: 1977-01-19
Abstract: The safety control unit is for a stamping press and is incorporated in The press's control unit. It ensures that the press is not activated should an error occur either in the control unit itself or in the safety unit of if received operational information deviates from that expected. The information is fed to two identical signal processing units (20,21) so designed that they can receive the signal in a predetermined way in a certain time sequence. An output signal is produced if the sequence and time scale is correct and two signals are fed to two operating units (6,7) both of which must be activated if the press is to function. If only one unit is activated or the internal signal processing is out of sequence then the press cannot be operated.
