Patent DE-3644794-A1 (DE)
Title: Loudspeaker fastening element
Inventor: POLLICH SEBASTIAN-GABRIEL
IPC: F16B13/06
Filed: 1986-12-31
Abstract: During the mounting of car loudspeakers in door linings or the like, either the latter have to be removed or complicated handling operations make work more difficult. The new loudspeaker fastening element makes possible the reliable fastening of car loudspeakers in a small number of operations, without removing the door linings or the like. The loudspeaker fastening element is composed of a supporting part, the base bolt, a part reaching round the back, the expanding sleeve and a clamping screw. The expanding sleeve which is placed on the clamping screw and is connected to the base bolt has four longitudinal slots which extend over three quarters of its entire length. After insertion through the car loudspeaker casing and the door lining or the like, the expanding sleeve is pulled towards the supporting part by rotation of the clamping screw and expanded until the supporting legs, which are rigid in the direction of load, come to rest against the rear of the door lining and in so doing press the car loudspeaker casing tight against the door lining or the like. Owing to its properties, the loudspeaker fastening element is suitable for rapid and lasting fastening of car loudspeakers in door linings or the like and can be released again at any time.

IPC: D21H25/08
Filed: 1987-04-08
Abstract: A process for the impregnation of flat fibrous materials such as, for example, cellulose paper webs or the like, to produce laminating materials with high surface strength for the coating of sheetlike base materials of all kinds. The impregnating agents used are preferably condensable or polymerisable synthetic resins are used as the impregnating agents incorporated into the fibrous material and, after curing, the impregnated material is stored, for instance in reel form, and/or despatched for use as an intermediate product for subsequent permanent bonding with the surface of the flat-shaped base material. The impregnating agent in the form of a highly concentrated solution of resin with a solids content of at least approximately 70% is continuously and homogeneously applied to the fibrous material webs at room temperature at a viscosity from 200 to 2,000 mPa.s. This is followed by heat treatment at up to 100 DEG C over a period which is relatively short compared with the curing period for the resin compound. <IMAGE>

Patent DE-3736031-A1 (DE)
Title: Electric tool for connecting cable wires to insulation-piercing plug connectors
Inventor: BARKOW HELMUT
IPC: H01R43/01
Filed: 1987-10-24
Abstract: The electric tool is intended to be used for pressing a wire into an insulation-piercing plug connector without exerting any manual force, in order to produce an electrical contact. In this case, the entire movement sequence is intended to be carried out largely automatically, so that the user merely needs to apply the electric tool and remove it. Provided in the electric tool is an electric motor which drives a plunger via a threaded spindle and presses against the insulation-piercing plug connector. At the same time, two centring levers which are mounted at one end are controlled by the movement of the plunger and are moved to latch with the insulation-piercing plug connector. The further forwards movement of the plunger results in the pressing-in and cutting-off of the wire. The electric motor is then switched over to run in reverse, so that the electric tool can be released from the insulation-piercing plug connector. The electric tool is used wherever screwless and solder-free connecting techniques are used for the connection of telecommunications equipment and for cable distributors.

Title: Method and installation for renewing areas covered with large concrete slabs
Inventor: HAHN PETER
IPC: E01C23/10
Filed: 1988-11-14
Abstract: To renew areas covered with large concrete slabs, in particular runways and standing areas at airports, use is made of a method and an installation in which firstly the covering layer and the intermediate layer are sealed or closed off again by means of an injected two-component resin. Cracks which have arisen therein are closed off and corresponding cavities are filled by means of the injected two-component resin. After brief curing of the injected material, further two-component resin is then pumped in in order thus to lift the concrete slabs back into their initial position. This does away with the need to destroy the concrete slabs and repair the intermediate layer and, if necessary, the covering layer, it being possible rather to inject the two-component resin in the three phases described through the concrete slabs to be renewed in order then subsequently to achieve not only effective sealing but at the same time also effective supporting of the concrete slabs to be renewed. The bores made in the concrete slabs are filled either with concrete or else with two-component resin, so that renewal which is rapid and, surprisingly, produces a multiple effect is possible. To carry out the method, use is made of an installation which, as a mobile unit, can be rapidly brought to the particular place of use and used there, after making the bores in the concrete slabs to be renewed, in the individual phases for a very short time ...
