Title: Process for producing a plastic sheathing for a flexible rod and a plastic-sheathed rod produced by this process
Inventor: SCHUSTER HUBERT
IPC: B29C45/14
Filed: 1988-07-05
Abstract: Conventional rods, shafts, cables, wires etc. which readily bend or bulge under radial effects can be sheathed in plastic by known means. However, sheathings in a dipping bath or else sheathing after placing in an injection mould never result in a plastic sheathing with a uniform wall thickness. To sheath a readily bendable rod uniformly thickly without any problems in a plastics injection mould, it is provided that the rod (5) to be placed into an injection mould has pushed onto it a centring sleeve (15) which is displacable on the said rod and is mounted next to the screw (21). During the injection-moulding operation, the centring sleeve (15) is displaced automatically in the manner of a perforated plunger on the rod (5) to be sheathed by the injection pressure, with the rod being centred the whole time. The process is suitable in particular for the uniform plastic sheathing of aerial rods. <IMAGE>

Title: Glass melting furnace for high melting and refining temperatures
Inventor: PIEPER HELMUT DIPL ING
IPC: C03B5/027
Filed: 1988-07-21
Abstract: Known glass melting furnaces for said purpose have considerable wear on the refractory material and/or an unstable temperature layering inside the glass melt, which leads to losses of quality in the molten glass. The new glass melting furnace is intended to avoid these disadvantages. The new glass melting furnace is characterised essentially in that it consists of two concentric, round or polygonal parts which are separated by a molybdenum pipe and are interconnected in their lower part. The outer part serves as melting part and the inner part as refining part. The glass extraction opening is provided centrally in the furnace in the upper part of the refining part. In the new glass melting furnace, an advantageous temperature distribution and glass melting flow are achieved for the melting process and the refining process and very high constant glass qualities can be produced. The new glass melting furnace is suitable in particular for manufacturing glass with particularly high quality in relatively small quantities. <IMAGE>
