Patent DE-2414819-A1 (DE)
Title: Injection moulding esp. for thermoplastics with vibration - applied to mould surfaces to improve flow conditions and quality
Inventor: HERBST RICHARD
IPC: B29C45/56
Filed: 1974-03-27
Abstract: A method of injection moulding thermally deformable materials, esp. thermoplastics , elastomers and duroplastics, operates by injection of the material into the open or virtually open mould under pressure and optionally with external influencing of the temperature. One or more of the surfaces or surface regions of the mould in contact with the material is vibrated. Vibration may be applied, esp. at low frequency, during the filling operation. High frequency vibrations may also be used. In particular, surfaces adjacent or in the sprue may be vibrated, esp. transversely to the flow direction or in torsional vibration. the vibration pattern may be varied during and after the injection cycle and aimed in particular at reducing the separating and ejection forces required. The process gives improvement in the ratio of flow path: wall thickness, in the back pressure required and in the final quality of the product.

Title: Electrical connector forming part of steering column switch - in which connecting pins are inserted after wiring
Inventor: ERDELITSCH HERBERT
IPC: B60Q1/42
Filed: 1974-05-15
Abstract: The application is to multi-position switches mounted on the steering column of a vehicle and operated by a control lever which can move in two planes. The connections to the switch are made by a contact carrier (10). Wiring is facilitated if the terminals fitting the contact carrier can be fixed to the incoming leads before assembly. A simple construction is to provide the edge of the insulation plate forming the carrier with recesses. If each recess is more than a semicircle the resulting projections act as lateral restraint for the terminals. Collars on the terminals separated by a distance equal to the carrier thickness provide the axial location.

Title: Multilayer impermeable plastic strips mfr. - by bonding polyethylene strips with asphalt mixt.
Inventor: ZULOAGA AMAT EUSEBIO DE
IPC: B32B25/08
Filed: 1976-02-05
Abstract: Impermeable laminate is formed by feeding two polyethylene strips (1A, 1B) in spaced relation to each other while applying a layer (6) of a mixture of 65-70% asphalt, 25-30% slate shale and 5-10% latex or latex type elastomer between them at a temperature of 170 to 190 degrees C, so that the strips and mixture are bonded together under pressure. The improvement is that the polyethylene strips are simultaneously cooled by a water film applied to their outer surfaces at a distance of 20-40 cm before contact between the strips and the asphalt mixture. Film of water applied to the polyethylene strips prevents the hot asphalt damaging the polyethylene while the asphalt is hot enough to bond securely to the polyethylene. As an impermeable strip for damp proofing floors. The asphalt is applied to the nip between a pair of rollers (3A, 3B) over which the polyethylene strips are fed, the rollers feeding water into contact with the strips.
