Title: Continuous insulation of wires - by applying polymer layer by condensn polymerisation from gas phase using glow discharge
Inventor: DASZKOWSKI ANDREAS DR
IPC: H01B13/06
Filed: 1974-09-20
Abstract: Continuous insulation of wires is effected by applying a polymer layer by polymsn. from the gas phase using a high frequency glow discharge technique, employing electrodes connected to a high frequency generator. The wire is cooled by leading into a first vacuum chamber, and guiding over a cooling wheel into a second, larger vacuum chamber. The monomers are converted from the solid or liq. phase to the gas phase in heated containers, and passed through a valve for controlling the gas pressure, and a heatable pipe to the second reaction chamber. This chamber contains tubular electrodes, and the wire is passed through the first electrode, over a reversing roller, and through the second electrode. The gas vapour present in the chamber simultaneously condenses and crosslinks/polymerises on the wire as this passes through the chamber to a winding spool. Simple, economic process effecting continuous coating. Use of drying ovens and stripping devices is avoided. Low energy consumption. Gives uniform coatings on both very thin and profiled wires. These coatings are free of defects, such as blisters. A wide range of monomers can be used, e.g. styrene, benzene, phthalic acid, dibutyl phthalate, trimellitic acid, diamines, glycols, and silanes.

Title: Impact ripper for coal mining - delay device retards reversal time from active to return strokes by flow resistance
Inventor: PHILLIPS REGINALD ANDREW
IPC: B25D9/26
Filed: 1975-01-21
Abstract: Impact ripper for coal mining is retracted by fluid pressure medium and driven forward when the fluid is bled from the chamber of the piston and cylinder unit and has a pressure chamber to release stored medium during the active stroke. When the pressure in the chamber reaches maximum it reverses the return movement to initiate the forward stroke, using the ensuing low pressure in the chamber to re-start the cycle. The control line (14a, 14b), responsible for this process includes a time delay device (15) which can delay the point at which the impact stroke reverses into the return stroke. The device should be on a flow principle, having less flow resistance in the direction from the pressure storage chamber (12) to the control valve (13). The device may be a choke valve (17) whose parallel non-return valve (16) blocks flow in the direction of the pressure chamber.
