Title: Device for fixing a nameplate in a cabinet, especially in an electrical switching cabinet
Inventor: SCHWEIGER HELMUT
IPC: H02B1/30
Filed: 1981-03-31
Abstract: A device for fixing a nameplate in an electrical switching cabinet, in which especially L-shaped and/or Z-shaped profiled rods (sections) (74) are used for holding electrical installation apparatuses, has a transverse support (12) on which supports (24, 26) are integrally formed at one end and on whose other end a plate (16) is integrally formed, such that it can pivot via a film hinge (14) and to whose outer surface the nameplates can be fitted. Located on the transverse support are grooves which, together with tabs (32, 34, 66) which are integrally formed on the supports, are used for attachment to the profiled rods. In the so-called installed position, the plate (16) is snapped onto arms (90, 92) and is thus at right angles to the transverse support (12). <IMAGE>

Title: Friction wheel gear
Inventor: POWILLEIT HANSHERGER DIPL ING
IPC: F16H15/28
Filed: 1981-04-03
Abstract: The application is for a friction wheel gear for obtaining a continuously adjustable transmission ratio, the friction surfaces of which gear are designed in a rotationally symmetrical manner relative to the point of intersection of the swivel axes and pivot axes belonging to each friction wheel, and the swivel axes of which gear lie parallel to one another and perpendicular to the pivot axes. In order to alter the transmission ratio, the position of the point of contact of the friction wheels on the friction surfaces is altered by rolling the friction wheels on one another in the plane spanned by the pivot axes of the friction wheels by means of opposed swivelling about the points of intersection of the swivel axes and pivot axes. The friction surfaces are preferably designed as spherical caps about these points of intersection. An adaptation of the contact force to the torque to be transmitted is provided for. In order to ensure satisfactory rolling, the friction wheels are guided forcibly towards one another during swivelling. Further claims describe additional embodiments and operating aids. <IMAGE>

Title: Process for separating the layers of a layered planar structure
Inventor: HOLLWEG ANTONIUS J F DR
IPC: D06H7/00
Filed: 1981-04-10
Abstract: Process for separating the layers of a layered planar structure, in particular of a textile floor covering, for example a tufted carpet, a needle-punched carpet and the like, in which the individual layers or the components forming the layers are mechanically separated and led away and collected separately. For the separation, band knife splitting machines, which are known per se, may be used in particular. In the case of carpets, the separation of the pile layer may also be carried out by shearing. The process permits the materials of the components forming the individual layers to be separated, in a simple manner, in the essentially uncontaminated and undamaged state, by means of which they can generally be passed on for reclamation or reuse without further pretreatment.

Patent DE-3147607-A1 (DE)
Title: Device for monitoring the wear of refractory linings
Inventor: BRIELER WILFRIED
IPC: G01B7/06
Filed: 1981-12-02
Abstract: The invention provides a device for monitoring the wear of refractory linings. Hitherto such monitoring was carried out with thermoelectric test sensors such as thermocouples and a satisfactory picture of the state of a fairly large area of the refractory lining was only possible with a very large number of them. The invention eliminates this difficulty by using a plate which has high thermal conductivity, in particular a copper plate, and which extends parallel to the plane of wear of the refractory lining and is connected to the latter in a thermally conducting manner. This copper plate supports the thermoelectric test sensors, that is to say the thermocouples or temperature-measuring resistors, so that each of their values provides information about a very large surface region in which the plate having high thermal conductivity is thermally exposed.

Title: Ecologically friendly deep-sea mining
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: E21B25/08
Filed: 1982-07-09
Abstract: Starting from the rolling freezing grab, provided with dry ice, of the preliminary application, this rolling freezing grab, with two cables whose hanging end is wound many times around two cable pulleys of the grab cylinder, was introduced as an innovation for the submarine extraction of manganese nodules, in which arrangement rotary kinetic energy is produced from gravitational force according to the yo-yo principle in a rolling manner on the cable and a transversal movement on the sea bed is produced from this rotary kinetic energy. Such a "harvesting cylinder" is suitable as a nodule freezing loader and elevator on the sea bed. Offered as a second alternative was a harvesting cylinder which is free of a freezing grab and, with the same inertial drive on the sea bed, acts as a nodule cutter and as an attachment for the rolling freezing loader. The inertially operated nodule cutter was also designed as a nodule loader and elevator as a third alternative, where dry ice and its problems are eliminated. Finally, in a fourth alternative, the prospect was held out of applying the yo-yo inertial drive for the production of rotary kinetic energy from gravitational force to other technologies, e.g. to weapons in the wet and dry element.

Title: Shears for plate or sheet metal
Inventor: HORN HANS-JOACHIM
IPC: B23D33/10
Filed: 1982-10-19
Abstract: Manually actuated plate shears for sheet metal and plastics (Fig. 4) are described which are actuated by a lever system. In these shears, the largest opening (shear jaw) of the cutter pair (5, 9), a fixed stop (7) for the material to be cut, and the fulcrum of the actuating lever (16) are arranged on the side which is located opposite the operating side (18) of the lever system. This ensures that the shearing force (8) acting in a horizontal direction on the material to be cut during cutting acts in the same direction against the stop (7) as the shearing force, directed away from the body of the operator, of the free hand, with which the material (6) to be cut is prevented from being lifted from the shear table (4). Unintentional slipping of the material to be cut is thereby eliminated. The length of the shears coincides with a part of the lever length and reduces the overall length of the shears. <IMAGE>
