Patent DE-3136525-A1 (DE)
Title: Plastic elements with improved hardness and scratch-resistance and process for the production thereof
Inventor: SPYCHER ANTON ARTHUR
IPC: G02B1/04
Filed: 1981-09-15
Abstract: A weakness of plastic lenses is their low hardness and scratch-resistance in comparison to glass, which should therefore be especially taken into account in their production. An even greater problem is the boundary surfaces of composite lenses built up from glass and plastic, even if the plastic materials are otherwise sufficiently hard. It has been found that the weaknesses of the boundary surfaces at the adhesion points or adhesion surfaces of composite lenses, in particular of allyl carbonate synthetic resins which are bonded to glass with a polymeric bonding layer, are caused by catalyst absorption by the bonding agent during or before the polymerisation of the plastic. A Barcol hardness of at least 77, at all points at a distance of 1 mm or more from the polymeric bonding layer, is obtained by means of the formulation of the polymerisation catalysts. Mixtures of isopropyl carbonate and benzoyl peroxide, in particular, come into consideration for this.

Patent DE-3146511-A1 (DE)
Title: Grip-improving device for vehicles, in particular road vehicles
IPC: B62D55/04
Filed: 1981-11-24
Abstract: In vehicles, in particular road vehicles, there is a problem that when the road or ground conditions are bad the vehicle may become stuck as a result of softening of the ground or of snow, sand or the like. This risk is counteracted by using a tape-shaped element which, expressed roughly, is clamped around three wheels in an approximately triangular shape in such a way that one side of the triangle is facing the ground to be driven over. In this way, the specific contact pressure on the floor is considerably reduced. The grip-improving device can be easily attached to a normal vehicle wheel or attached in place of the same.

Patent DE-3229797-A1 (DE)
Title: Method and circuit arrangement for monitoring a data transmission system
Inventor: KORN JOEL DR ING
IPC: H04B17/40
Filed: 1982-08-11
Abstract: The invention relates to a method and a circuit arrangement to carry out the method for monitoring a data transmission system comprising fixed and mobile transceiver stations where the latter are in radio contact with the former, and a central station, connected to the fixed stations, whose continuously transmitted call telegrams are received by the fixed stations and forwarded to the mobile stations which immediately transmit their reply telegrams to the central station, in each case via the fixed stations currently assigned to them. According to the invention, the call telegram contains a synchronisation word which is evaluated in the fixed station, which, once the call telegram has been received and forwarded, waits to see whether a reply telegram arrives at a mobile station. If it does not arrive, a short telegram with monitoring messages is transmitted to the central station (Z) where it is evaluated (Fig. 1). This method ensures that the operational capacity of the entire transmission path, including all modems, lines and radio units, is constantly monitored automatically. <IMAGE>
