Title: Material-optimised sealing system of metal casings of galvanic elements
Inventor: KUEHL THOMAS DR
IPC: H01M2/02
Filed: 1981-08-18
Abstract: In order to produce a durable pressure seal between the metallic casing parts of galvanic elements, especially button cells, it is beneficial for the cup material to have a high module of elasticity (E  APPROX  210000 N/mm<2>), but for the cover material to have a relatively low module of elasticity (120000-150000 N/mm<2>) tantamount to high elasticity. A cell casing whose materials are optimised accordingly is formed, for example, by a nickeled steel cap and a cover made of a copper-beryllium spring material.

Title: Process for the purification of effluents and solutions and apparatus for carrying out said process
Inventor: FEOFANOV VITALIJ ANDREEVIC
IPC: C02F1/463
Filed: 1982-10-07
Abstract: The invention relates to environmental protection. The invention can be used particularly successfully for the removal of heavy metal ions, nonferrous metal ions and noble metal ions, organic substances, flotation agents and mineral oil products. The process comprises dissolution of a metal anode in the presence of an insoluble cathode and the precipitation of organic and inorganic admixtures on the resulting compounds. The precipitation is effected with the use of the cathode, whose material has a higher potential than the anode, during alternating contact of the electrodes with atmospheric oxygen and the solution to be treated. The apparatus for carrying out the process contains a drum (1) having openings (3, 4) for the supply of scrap iron and the solution to be treated and also for the removal of the residue and the treated solution. The internal surface of the drum (1) is provided with concentric longitudinal barriers (2). In the vicinity of the outlet opening (4) there is located the perforated dividing wall (5), which prevents the removal of the scrap from the drum (1). The scrap iron, loaded into the hollow space of the drum (1), acts as a soluble anode and is in contact with the cathode. The cathode used can be the copper-cladded internal surface of the drum (1). <IMAGE>

Title: Compressor
Inventor: LOWN HAROLD
IPC: F04D29/70
Filed: 1982-12-29
Abstract: An arrangement for generating a wet compression of gas, which is compressed in a multi-stage radial gas compressor (10), which has an impeller (14), a guide apparatus (17) "downstream" of the impeller and a transverse duct (18) connected to the downstream end of the guide apparatus, contains a number of liquid nozzles (24, 30) for injecting an evaporable liquid, such as for example water, into a gas flow which is compressed. The liquid nozzles (24, 30) are arranged axially symmetrically about the longitudinal axis of the compressor shaft (15) and in such a manner that they inject the liquid into the guide apparatus (17) essentially upstream of the transverse duct (18), and have a radial spacing from the axis which amounts to approximately 1.05 to 1.1 times the maximum radius of the compressor impeller (14, 22). A considerable increase in the evaporation of the injected liquid is achieved, which results in a better compressor capacity and lower wear of internal compressor parts. <IMAGE>

Title: Safety mast foot for sailboards
Inventor: PEUCKERT KONRAD
IPC: B63B35/79
Filed: 1983-01-13
Abstract: The invention relates to a safety mast foot for sailboards and the like, with a foot body, which can be inserted into an opening in the top side of the sailboard and is provided with a head body which can be put onto the top side of the board, and also a wedge body which is arranged with regard to the foot body in such a way that its side opposite the wall of the insertion opening can be brought into firm clamping contact with the wall and which, at its lower end remote from the top side of the sailboard, is pivotably mounted about a fixed, horizontal axis in the direction of the insertion-opening wall opposite it and can be pressed by means of a spring against this wall and can be clamped in place in the insertion opening and can also be moved out of its clamped position against the action of the spring by means of a foot lever acting on its upper end and projecting at least partly beyond the top side of the sailboard. Safety mast feet of this type have the disadvantage that they require considerable forces to lift the mast foot or the mast out of the insertion opening or the mast-foot case. The invention avoids this disadvantage by a locking device being located in the head body, which locking device, after the actuation of the foot lever effected to move the wedge body out of its clamped position, can be brought into engagement with the wedge body and prevents the latter, together with the foot lever against the action of the spring, from ... into its clamped position ...
