Title: Method for the continuous production of a wire of small cross-section and long length
Inventor: RYDSTAD HANS DR ING
IPC: B21B1/18
Filed: 1982-04-30
Abstract: Metallic wire of small cross-section is produced by isothermal or quasi isothermal rolling in one or two successive continuous rolling trains having heated rolls with increased cross-section reduction per roll pass and reduction in the number of passes, no drawing operations with intermediate annealing being required for the actual reduction in cross-section. As a result, the minimum cross-section limit customary with unheated rolls of about 24 mm<2> (5.5 mm DIAMETER ) with steel wire can be considerably lowered and it is possible to economise on drawing operations to the point of dispensing with them altogether. <IMAGE>

Title: Process for producing annular flanges for pipes, in particular ventilation pipes, the annular flanges and pipes consisting of thermoplastic, and a device for carrying out the process
Inventor: BRAUN JOSEF
IPC: B29D23/00
Filed: 1982-05-18
Abstract: To avoid a large amount of material offcut in the production of annular flanges, the invention includes a process for their series production, in which thermoplastic is extruded to form a solid-walled profile and the latter is wound helically in the deformable state, after which the helix is finally cut open along a circumferential line. As a result of the cutting open, a number of open rings are produced, corresponding to the number of helical windings, the end faces of which rings are butt welded to one another by means of a heating element. In this process, the final annular flanges can be provided with an annular groove on their one end face, into which a sealing ring can be inserted. The invention further relates to a device for carrying out this process, which contains a helical winding device with the aid of which the profile can be helically wound at a rate corresponding to the extrusion rate.

Title: Drive mechanism for converting rotary motion into linear motion
Inventor: MAYER MICHAEL
IPC: F01B9/02
Filed: 1982-09-04
Abstract: The invention relates to a novel drive mechanism for converting rotary motion into reciprocating linear motion or vice versa, which, even in short-stroke engines or compressors, moves the lifting pins, connected to the piston, of one or more rotating shafts in a straight line in such a way that no lateral forces act on pistons and piston rods. In this case, at least one shaft is used which revolves on a circular path and rotates about its own axis at the same angular velocity opposite to the direction of revolution. The shaft carries one or more lifting pins, whose eccentricity is equal to the radius of the said circular path and also has at least one crank journal, in which the distance between the axes of the eccentric shafts and the axes of the crank journals is equal to this eccentricity. From the total number of the axes of the crank journals and the revolving shaft, at least two axes are rigidly guided on separate circular-cylindrical paths of revolution with a radius corresponding to the said circular path. By special means, the axes are held at predetermined distances and, in addition, guided in such a way that the plane or planes laid through two of these axes are in each case shifted parallel to themselves. Moreover, means are provided for synchronising the rotation of the revolving shaft itself at the same angular velocity and in the direction opposite to the revolving motion of the axes.

Title: Fence element with three-dimensional profiling
Inventor: SCHAEFER BERND
IPC: E04H17/16
Filed: 1983-03-17
Abstract: Boundaries, in particular mobile fences, are composed of individual fence elements consisting of a large-area welded lattice and having supporting elements designed as bent edges and/or beads. These beads are preferably formed in the vertical direction and can be supplemented by additional rectilinear longitudinal wires. Bent edges are provided, in particular on the sides, either for better attachment of the supporting posts or as a replacement for the supporting posts. Besides the vertically running beads, double lattice fence elements provided with deformations are also possible, the welded lattices being connected to one another in each case by the transverse bars. Furthermore, diagonally running beads are possible, in which case bent edges arranged perpendicularly to the margin are to be arranged expediently at the margins, for stabilisation. With horizontally running beads and bent edges, the arrangement of additional longitudinal wires expediently on both sides of the bent edge is proposed, so as to achieve thereby the required stability values. <IMAGE>

Title: Process for treating the internal surface of superconducting cavities (cavity resonators)
Inventor: PROCH DIETER DIPL PHYS DR
IPC: H05H7/20
Filed: 1983-12-21
Abstract: An accelerator unit (1) cavity (7) made up of one or more individual resonators (2) is approximately half-filled with ceramic grinding bodies and with water and slowly rotated at about 9 rev/min. The rotation is maintained for about one week. This smooths the internal surface of the cavity (7) and frees it of defects in such a way that the cavity (7) can be used with appreciably improved properties and without difficulty in the superconducting mode. Specifically, the simple process specified makes possible to increase the longitudinal acceleration field strength achievable in practical operation by at least a factor of 2 or more, i.e. to eliminate at least half the acceleration units (1, 1'). To remove material abraded by the grinding bodies, the cavity (7) is also filled with an acid mixture of about 1 part of HF, 1 part of HNO3 and 6 parts of H3PO4 and thereby cleaned and superficially pickled. <IMAGE>
