Title: Overrun brake device with height adjustment for braked trailers
Inventor: GEISSLER JUERGEN
IPC: B60T7/20
Filed: 1981-05-23
Abstract: The invention relates to an overrun brake device with height adjustment for braked trailers comprising an approximately horizontal guide tube (4) fixed so that it is height-adjustable on the drawbar (10) of the trailer and a tie rod (3), supported so that it is displaceable to a limited extent in the guide tube (4) and fixable on a towing vehicle. The tie rod (3) is connected to a transmission device comprising a core (16) displaceably carried in a flexible casing (12), the transmission device being fixed by one end to the guide tube (4) and by the other end in the area of the drawbar (10). The known S-shaped laying of the flexible casing with core has the disadvantage that in the case of height adjustment for adaptation to different coupling heights the shape varies to an extreme extent resulting in considerable variations in the length of the transmission device, which cause inadmissible relaxation and tensioning of the brake linkage. According to the invention it is proposed to lay the casing (12) with the core (16) in an open, U-shaped bend of approximately 180 DEG  between guide tube (4) and drawbar (10). Surprisingly it has been shown that such a shape remains largely unchanged even in the case of extreme height adjustments so that no changes in the length of the transmission device occur influencing the brake linkage. The invention is shown in Fig.1. <IMAGE>

Patent DE-3136638-A1 (DE)
Title: Panelled wall
IPC: G09F15/00
Filed: 1981-09-16
Abstract: The invention relates to a panelled wall, in the case of which, in contrast to known panelled walls in which panel boards, of the height of a room or half the height of a room, are fitted together directly by means of a groove/tongue connection and are usually positioned on a substructure, the panel boards are introduced between neighbouring panelled-wall bars. This makes it possible both to use short and thus inexpensive panel boards and also to mount the panel wall by DIY. Moreover, it is possible to exchange various divisions of such a panelled wall without difficulty, and the same goes for attaching superstructures, partition boards and shelves. <IMAGE>

Title: Meat coiling machine
Inventor: WIEGAND GEB HAHNER
IPC: A22C7/00
Filed: 1981-10-08
Abstract: The invention relates to a meat coiling machine for coiling collars, rolled ham or the like. In known machines of this type, the thread has thus far been guided along the coiling cage by hand, in which connection, however, as a result of the non-uniform tension and of the non-uniform movement along the cage, there were non-uniform coils which did not ensure the dimensional stability of the rolled product during further processing. According to the invention, it is envisaged to provide a thread-guiding element which can be moved by the rotary drive of the cage and which is arranged displaceably along the cage in a guide rail. To achieve a uniform thread tension, a thread-tensioning device is provided on the thread-guiding element.

Title: Gangway protection between two vehicles, in particular rail vehicles, connected to one another in an articulated fashion
Inventor: KUEKER WOLFGANG DIPL ING
IPC: B60D5/00
Filed: 1981-12-05
Abstract: The gangway protection is composed of a multiplicity of continuous tubular beads made of rubber or a different elastic material extending parallel to the attachment edges along the vehicles and as a result arranged transversely with respect to the travel direction. In order to reduce the wear of this gangway protection, which wear results from the fact that both jolts and extensions, for example when travelling around a bend or through points, are absorbed exclusively by the beads and in order to keep the noise and heat insulation constant, the gangway protection is constructed in such a way that jolts are absorbed by the beads and extensions are absorbed by means of webs between the beads which can be pushed into one another in a telescopic fashion.

Patent DE-3222722-A1 (DE)
Title: Super heat pump
Inventor: FIEDLER WILHELM
IPC: F25B29/00
Filed: 1982-06-18
Abstract: The super heat pump does not operate as a (flow-compensated) piston-cylinder machine, but as a mechanically isolated tube circuit process or cyclic flow process. This process is intended to raise 1-temperature ambient heat Q(TA) to the temperature TA +  DELTA T( DELTA h).  DELTA h/1 = mechanically effective gradient of the ambient region. The mechanically closed tube circuit contains a gaseous circulating medium and consists of two mutually inverse compression tubes (confuser and diffuser). Under the effect of speed of revolution and a stationary force field of external origin or determined by the cross-section, tube regions with conservative pressure and temperature differences are produced. They permit a heat input into the tube circuit of Q(TA) and a heat output of Q(TA + DELTA T( DELTA h)), without the transforming heat passage being able to lead to pressure disturbances of the circulation medium, bringing about losses. This innovation has a practically attainable efficiency factor <IMAGE> (T2 = Carnot-pumped temperature) as a result and thus makes possible an extensive use of previously lower-valued 1-temperature heat for heating, cooling, and the operation of heat engines.
Patent DE-3233917-A1 (DE)
Title: Power-operated chuck for machine tools
Inventor: ROHS HANS-GUENTHER PROF DR ING
IPC: B23B31/14
Filed: 1982-09-13
Abstract: The invention provides a power-operated chuck for machine tools, in particular lathes, in which the chuck stroke of the chuck jaws for chucking a workpiece is effected by means of a chucking drive of the lathe. Since the chuck stroke is small in this power-operated chuck so that the rules for the prevention of accidents are complied with, and thus the application of a centrifugal-force compensation for adaptation to workpieces of different diameters can be carried out automatically and safely and accurately while taking little time, the chuck stroke of the chuck jaws can be displaced in the chucking area in a positive-locking manner in the chuck by an adjusting drive independent of the chucking drive.
