Title: Method for connecting rod-shaped building elements and connecting element and tool for carrying out the method
Inventor: HORSTMANN GERHARD ING GRAD
IPC: F16B2/26
Filed: 1982-06-21
Abstract: When connecting rod-shaped building elements, in particular concrete-reinforcing rods, there is the problem of reliably securing them in position using simple connecting elements and tools. To solve this problem, use is made of a stirrup-shaped connecting element having at least one stirrup leg (DK) which is break-proof and permanently deformable towards the inside of the stirrup with a curvature corresponding to the stirrup vertex (BST). With appropriate flexural strength, the stirrup legs can thus in principle bring about the desired securing in position without further fastening means. In addition, it is advisable, if desired, to provide material connections between the stirrup legs or between these and at least one of the building elements, preferably by means of weld joints. The tool used to solve the problem comprises a stirrup-holding device (HV) and a counterpressure piece (GD) having guide channels (SF) and abutment faces (WF) for the leg deformation towards the inside of the stirrup. The holding device and counterpressure piece are mounted on a supporting device (TV) so as to be movable relative to one another in accordance with the deformation and are connected to a mechanical drive device (AV). <IMAGE>

Inventor: LINGNAU HORST
IPC: F16K11/044
Filed: 1982-09-08
Abstract: A 3/2-way valve having a control piston in the interior of the valve housing. It is intended to be possible to slow down the opening and closing speed of the valve in an adjustable manner, and to subject its sealing surfaces to little wear. As the drawing in Fig. 1 shows, this is achieved in that the control piston (1) extends with a piston rod (1d) and an additional piston (1e) to in front of a compression space (4) which can be connected via a valve seat (10) and a valve cone (7) to a line (6) which leads into free space. The control piston has a radial hole (1c) between its sealing surfaces (1a, 1b), the valve seats (2, 5) and a bypass opening (14), which radial hole (1c) is connected to a hole (3) which is guided centrally through the piston rod (1d) and has a constriction point (9), which is connected to the pressure space (4) and has a variable cross-section which is smaller than the cross-section of the passage of the opening of the valve seat (10). <IMAGE>

The zinc naphthenate applied in excess to one side of the mica paper (G) can also be used at the same time as adhesive (K) for bonding mica paper (G) and backing (T). Impregnatable fine mica strips according to the invention are suitable, in particular, for high-voltage insulations for electrical machines which can be produced by the epoxy-resin impregnation process. <IMAGED>
Patent DE-3236319-A1 (DE)
Title: Energy store for storing latent heat in chemically reacting storage media or storage media with a phase change
Inventor: LAUMEN MICHAEL
IPC: F28D20/00
Filed: 1982-09-30
Abstract: An energy store (23) is proposed for storing latent heat in chemically reacting storage media or storage media with a phase change. An inner container (24) contains a storage medium (32), for example a reciprocal salt pair, having a specified reaction temperature. Flowing through said storage medium (32) is a dispersant (39) whose evaporation temperature is less than or equal to the reaction temperature. While flowing through the storage medium (32) the dispersant (39) consequently evaporates and in doing so essentially absorbs heat of evaporation. The evaporated dispersant collects in the upper section between the inner container (24) and an outer container (25). Disposed in the intermediate region (26) formed by the two containers (24, 25) is a coiled pipe (27) which has a heat transfer medium (30) of an installation circuit flowing through it. The dispersant (39) cools at the coiled pipe (27) and condenses, releasing the heat of evaporation absorbed. This forms a dispersant circuit which is maintained by the difference in pressure between the dispersant condensate and the dispersant in vapour form. This achieves a direct heat exchange between the storage medium (32) and the dispersant (39). The required mixing of the storage medium (32) is brought about by the dispersant (39), the necessary kinetic energy being drawn from the store potential. In addition, the energy store (23) can be of compact and space-saving construction. <IMAGE>

Title: Apparatus for centring for the production of a centre hole in discs
Inventor: PIETZSCH KARL DIPL PHYS DR RER
IPC: G11B23/00
Filed: 1983-01-05
Abstract: In the production of optically readable information media, in particular audio and video discs, which contain information in the form of circular or spiral information tracks and have an information-free centre, very high requirements must be demanded of the central arrangement of the centre hole fixing the axis of rotation. In order to be able to perform the centring quickly and reliably with high accuracy even in cases of disc undulation, it is proposed by way of modification of the centring apparatus defined by Patent Specification DE 3012433 C1 to scan the borderline between the information tracks and the information-free centre simultaneously by a plurality of light beams focused on the disc surface, which beams thereby come to lie at equal rotational angles on the circular borderline between the information tracks and the information-free centre. The criterion for centring the disc, which in this case carries out merely a translatory movement in the x-y plane of the disc, is achieved when the points of impingement of the partial beams, which are moved periodically towards each other and away from each other by means of an oscillatory mirror, simultaneously cross over the borderline from the space of the information-free centre to the information tracks. <IMAGE>

Title: Anchoring piece for insulated supporting cables
Inventor: WUNDERLICH GUNTER DIPL PHYS
IPC: H02G7/05
Filed: 1983-05-16
Abstract: The invention relates to an anchoring piece for the installation of insulated supporting and anchoring cables. The aim and object of the invention are to develop an anchoring piece which involves a low production and installation cost and by means of which it is possible to distribute the forces acting on the supporting cable so favourably that damage to the supporting cable and to the plastic or elastic sheathing is avoided as far as possible. The object is achieved according to the invention in that a flat metal or plastic body with a rough surface is used as the anchoring piece, which body has three perforations of round shape at equal intervals on its longitudinal axis. These perforations are provided in each case with a slot, alternately upwards and downwards, which slot is broad enough for the supporting cable which is to be anchored to be passed through. At the same time, the slots are designed such that it is not possible for the installed supporting cable to slide out on its own. An indentation is located in the clamping-field direction, parallel to the slot in the central perforation. All edges are highly rounded.
