Title: Cord drive belt - is formed from twisted cores coated with plastics to be wound into layers and fused together
IPC: B29D29/00
Filed: 1990-06-27
Abstract: The cord drive belt, which is fitted with surface balls for gripping, is made from continuous core yarns which are treated with a clinging agent before winding around two winding drums and coated with plastics so that they are twisted as they are wound round the drums round the already-laid wound layers. The twisted strand so formed is drawn from both winding drums and passed through a heated jet to melt both sides of the layers together. The material is then given an outer cladding, and the surface balls are applied. The continuous wound and twisted core yarns are of an aromatic polyamide, especially aramide with a thickness of about 200 dtex. The cladding plastics mantle is pref. of polyurethane or a polybutylene terephthalate and a long-chain polyether glycol as an elastic block polymer, especially Hytrel (RTM). The plastics mantle cladding is applied before the yarns are wound, using pressure extrusion at extrusion jet temps. of 175-240 deg.C Two opposing and rotating slitted discs are used to melt the yarn layers, or an assembly with two pivoting jet half sections. ADVANTAGE - The drive belt material has a high homogenous character, and the low stretch components are sealed in place to prevent the development of weak points.

Title: Interrupting set=up for respective voltage supplies for vehicle drives - includes electrical circuit with switch or key for each vehicle operated in emergency
Inventor: LOSKE GUENTER ERWIN
IPC: B60L15/38
Filed: 1990-06-29
Abstract: Each vehicle is provided respectively with a switch or key (T1, T2) for the emergency interruption. Upon operation, the voltage supplies in the other vehicles are correspondingly capable of being interrupted. Each vehicle has an electrical circuit with the associated switch or key of this vehicle, such that the electrical circuits of the vehicles are coupled with each other in series. With operation of the switch or key of any vehicle, and thus an interruption of the voltage supply, the voltage supplies in the other vehicle can be interrupted in the manner of a chain reaction, by the associated electrical circuits. The system is only operated if the interruption circuits as well the voltage supplies in the individual vehicles have been activated beforehand by the operation of a response switch or key (QT). USE - Coupled vehicles esp. mining vehicles.

Patent DE-4042063-A1 (DE)
Title: Making effective reinforcements for FRP - by weaving or knitting main fibres with ancillary fibres to form loops so that these are extended when finished prod. is loaded
Inventor: SCHWARZ GERHARD DIPL ING DR
IPC: B29C70/56
Filed: 1990-12-28
Abstract: Fibres/fibre composites are produced for reinforcing plastics by forming woven or knitted fibres/composite plastically or elastically with ancillary fibres so that they are corrugated or made into open loops which are readily embedded in the plastic material. Aramid fibres are knitted together with the subsidiary fibres so that after shrinking the loops of the reinforcing fibres are held together like links in a chain. The material can be stretched until the loops recover their original form. Using a suitable temp. the three-dimensional form of the material can be fixed. The extensibility of the fibres greatly affects the loads which can be used. ADVANTAGE - The failing loads (where the component materials separate) are determined by failure of the stretched fibres. If the material does fail it delaminates rather than breaking up completely hence giving increased energy absorption. Displays a three-dimensionally residual plastic deformation of the fibre composite rather than suffering change or loss of the composite structur

Title: Producing cpd. fibre component for artificial joints, etc. - in which cut section of laid continuous filaments in required orientation to be rolled is used to give the component irregular contour shape
Inventor: DIERL RUDOLF
IPC: B29C70/34
Filed: 1991-01-17
Abstract: To produce components with an irregular contour, from a cpd. fibre material, a layer (38) of continuous filaments (32) is formed with the fibres in the required orientation. The layer is then cut into a section (35) which, when rolled, forms the shape of the required component (30). The roller component blank is then compressed and hardened. A displacement body can be used to support the wound fibre material section. Pressure is applied to the component during the hardening process. A shrinkage hose can be drawn over the rolled section which shrinks under heat, and is removed after cooling, and the component is passed to a hardening stage. After the cut section (35) has been rolled, it can be covered by a braided material (39) to be shaped, compressed and hardened. USE/ADVANTAGE - The technique gives a component with a varied cross section structure which can be reproduced, either as a solid body or with a core where the material is wound round it, with the fibres in their correct orientation. The component can be used, for example, as the shaft of an artificial join
