Title: Tennis racquet with double membrane - placed over centre area of strings causing flashlight in transparent handle when hit
Inventor: SCHEURER MAX
IPC: A63B69/38
Filed: 1979-10-20
Abstract: A tennis racket has in the centre area (5) of its strings a double membrane (6) with a resonance frequency of 200-600 Hz so that every time the player hits the tennis ball an acoustic feedback confirms a good hit whereas lack of that feedback indicates a less skilful hit. The membrane may be a double membrane with the racket strings passing through the clearance space between. Another method of indicating to the player an assessment of his hit performance consists in the provision of a camlike contact plate (10) and an orthogonally arranged similar plate (18) at the rear of the racket. Pointed protrusions in one cam serve as contacts and when the centre area is hit by the ball, the consequent displacement of the cam tongues causes momentary closure of one or more contacts, thereby bringing battery (B) over wires (21,20) into action, causing an electric flashlight (L) to be lit with the aid of an electronic converter (E). By making the racket handle (1) transparent the flash light can be perceived by the player.

Title: Aligning appts. for continuously cast slab on roller track - comprises adjustable limit stop, is esp. for accurate, longitudinal flame cutting of wide slab to obtain several narrow slabs
Inventor: HEIN KARL
IPC: B23K7/10
Filed: 1980-03-05
Abstract: A slab made in a continuous casting machine travels along a roller track until it is located under flame cutting burners. A transverse conveyor is then used to move the slab sideways until it touches a limit stop, which is fixed on a roller disc. The sideways movement of the slab then rotates the disc through an angle to establish a reference line along which burners travel to cut the slab. The disc is pref. mounted on the end of a lever lifted by a work cylinder so it is in frictional contact with the slab. The invention can also be used to align flat rolled plates prior to flame cutting.

Title: Expanding plastics wall plug has conical ridges - each with flexible peripheral rib to adapt to hard or soft material
Inventor: FRISCHMANN ALBERT
IPC: F16B13/12
Filed: 1980-08-16
Abstract: An expanding plastics wall plug or dowel has a series of conical anchoring ribs at its forward end, splaying arms to permit expansion in this zone, and a tubular portion at its rear end into which the screw is initially inserted. The circumferential conical anchorage ribs each carry radially projecting, annular, elastically deformable ribs at their perimeters. With this arrangement, when driving into a soft material, the projecting ribs anchor in the material, whereas when driving into a hard materials (as shown) the elastically deformable ribs bend over, prevent the screw from jamming in the plug, and provide a more uniform bearing area on the surrounding mortar or concrete. Pref., the dia. of successive ribs decreases towards the point of the plug. Their external dia. is pref. larger than that of the tubular portion of the plug.

Title: Roll crusher for abrasive prods. - with superhard housing and ceramic bushes for roll support
Inventor: BONORA BENITO
IPC: B02C15/08
Filed: 1980-11-14
Abstract: A roll crusher, for grinding strongly abrasive products such as cocoa, chocolate, lacquer, paint, enamel etc., has on the inside of the mill housing a Brinell hardness of over 700. The grinding rolls are made in one piece, preferably of cutting tool steel. The shaft ends of each roll are supported in bushes, made of a material with a high mechanical strength, preferably ceramics. This eliminates the short service life of 500-600 h for such roll grinders which is caused by the very abrasive nature of the material. It also reduces the content of iron particles in the ground material to well under the legal limits.

Patent DE-3115132-A1 (DE)
Title: Pipeline system preferably suited for refrigerant operation and the like
Inventor: PFEIFER JOHANN B
IPC: F24D15/02
Filed: 1981-04-15
Abstract: With the encapsulation of a pipe which can be subjected to pressure, e.g. a refrigerant-channelling pipe and/or its casting into a pressure-resistant material which solidifies well, protection against outflowing gas and/or liquid, for example refrigerant, is achieved. A particular advantage of this pipeline system is that, owing to the core pipe as condenser, the refrigerant can be used, without danger and without a high-loss heat-exchange process, directly for heating purposes. The incorporation of a shut-off valve into the return pipes of each heating circuit brings about material-saving and cost-saving effects. As a result, the return pipes can be kept smaller in diameter than the supply pipes of the heating circuit. A material-saving advantage is obtained in that the release valve incorporated into the return of each heating circuit (heat-discharge circuit) can be connected directly to a heat-receiving circuit fitted on the outer wall. A further advantage is achieved if the interspaces between core pipe and protective casing are connected to a water-channelling pipe system, because then the pipeline system can be used from time to time, i.e. as required, as an instantaneous heater and/or for preparing hot water.

Title: Arrangement for adaptive equalisation
Inventor: FRIEDRICHS BERND
IPC: H04L25/03
Filed: 1981-05-27
Abstract: The invention relates to an arrangement for adaptive equalisation of an at least three-stage redundancy-added communications signal which is to be transmitted via lines in the baseband. The equalisation of a multi-stage signal incurs high cost. According to the invention, this cost is substantially reduced by converting the received multi-stage communications signal into a binary signal with the aid of a filter before the equalisation. The binary signal can then be equalised in a simple fashion.
