Patent DE-3136239-A1 (DE)
Title: Cable collar
Inventor: LANGMATZ HANS
IPC: H02G9/06
Filed: 1981-09-12
Abstract: Known cable insertion funnels which protect cables which are passed into or passed out of cable traction tubes or blocks against the ingress of earth, sand or the like, have the disadvantage that, before use, the funnel cone must be cut off from the end to match the diameter of the cable which is respectively being guided. If this is not done accurately, the cable can be pulled only with great effort or a gap remains between the funnel internal diameter and the cable external diameter. The cable collar according to the invention makes manual operations for matching to cable sizes superfluous and consists of a collar body, which is formed from shells which are connected by a hinge, and of an insert which, in the closed state, fills the internal space between the shells and consists of a material which is softer than the material of the collar and has alternating projections and depressions. If the collar is closed around a cable which of equal diameter and is inserted into a cable traction tube, the insert completely fills the space remaining alongside the cable cross-section, without any gap and in a sealing manner. <IMAGE>

Title: Device for mass transfer between fluids
Inventor: KNOTHE ERICH ING GRAD
IPC: B01D63/14
Filed: 1981-11-03
Abstract: A device for mass transfer between fluids, utilising a pressure gradient and/or concentration gradient as the transport mechanism, consists of a ply of support mat (22), a membrane (5), a flow divider (6, 26, 36) in the form of a fluid-tight embossed film, a further membrane (7) and a further support mat (22), all five plies together having been pleated to give a folded pack and being enclosed in a surrounding housing (4) in such a way that, by means of sealing beads (8) in the region of the end faces of the folded pack, three mutually separate flow chambers (I, II, III, III') are formed and the device is suitable as a dialyser and/or as a filter, also for the treatment of blood in the medical field. The support mats (21, 22) are slightly compressible and have a quasi-planar surface, by means of which the membranes (5, 7) are provided with a corresponding planar support on the inactive side. Under the pressure in the third flow chamber (III, III'), the support mat (21, 22) is slightly compressed, so that the flow divider (6, 26, 36) assumes a contactless intermediate position between the two membranes (5 and 7) in such a way that laminar flow of the fluid in the third flow chamber (III, III') can take place over the projections (6', 27, 37), facing the membrane surfaces, of the flow divider (6, 26, 36). The housing end plate (4c) facing the fluid inlet in the third flow chamber (III, III') is treated with special lamellar fins (32) which divide the fluid stream in the inlet channel (30) into a multiplicity of lamella channels (31) which become smaller and wider in the downstream direction corresponding to the intended fluid distribution over the cross-section, the lamellar fins (32) shaped with a saw tooth cross-section bearing with their sharp edge against the front edge of the folded pack and sealing the lamella channels (31) from one another. <IMAGE>

Title: Device for cooling electrical or electronic components which produce lost heat
Inventor: BOGS HARTMUT DIPL-ING
IPC: H05K7/20
Filed: 1982-02-11
Abstract: This device for cooling electrical or electronic components which produce lost heat, such as resistors (3), thyristors, diodes, capacitors etc., has a housing (1) which is closed at the top and open at the bottom and which has a baseplate (2), preferably made of ceramic. The baseplate (2) serves as a support for the components (3) in the interior of the housing, preferably thick-film or thin-film power resistors. The interior of the housing is potted in an elastic insulating compound (6). The connecting elements (4) of the components (3) pass through the housing lid. The housing (1) is mounted on a heat sink (9) which comprises a platform (10) having the dimensions of the baseplate (2). During the fixing of the housing (1) with the aid of screws (12) and nuts (13), the platform (10) pushes the baseplate (2) into the interior of the housing and consequently compresses the elastic insulating compound (6). This produces a mechanical prestressing, i.e. a homogeneous surface pressure between the baseplate (2) and the heat sink (9), which surface pressure is intensified still further while the components are in operation as a consequence of the components (3) being heated, and this makes it possible to transmit high power loss densities in a uniform, potential-free manner. <IMAGE>

Patent DE-3221035-A1 (DE)
Title: Front axle for utility vehicles
Inventor: WOHLFARTH PETER
IPC: B62D5/12
Filed: 1982-06-04
Abstract: In a front axle for utility vehicles, the wheels are mounted on axle legs which are coupled to one another and which carry out steering movements. The steering movements are brought about by means of a direct input of the steering gear into one of the axle legs. A considerable simplification of the steering system is thus possible in that neither is the steering gear to be equipped with a steering arm nor is a steering rod to be provided. The steering system thus requires considerably less expenditure, it being possible to install the steering gear on the front axle in the region of one axle end in a space-saving manner.
