Abstract: In a tubular reactor carrying a bed of solid material into which carbon electrodes project for heating the material upon passage of a current, the outside ends of said electrodes being connected to metallic conductors in turn connected to a supply of current, the invention involves pouring lead about the end of each electrode to effect improved contact between the electrode and its respective metallic conductor. The process involving use of such electrodes to react carbon with chlorine and the oxide of silicon or metals such as vanadium, titanium or zirconium is also covered.

Abstract: Process and apparatus for the production of a fuse having a cavity extending axially within the explosive core and being provided with a lining. The process includes the steps of continuously producing a casing at the lower end of the feed hopper, introducing an explosive from the feed hopper into the casing, passing the lining through the feed hopper while continuously winding filaments therearound in a helical manner for centrally guiding the lining through the feed hopper, and continuously introducing the lining together with the explosive into the casing at the end of the feed hopper. The apparatus includes a draw-off mechanism arranged vertically above the feed hopper, and one or more supply bobbins for the filaments can be provided as well as a bobbin for a tracer thread.

Abstract: Synthetic resinous bodies especially in sheet form, such as plates, foils, webs and non-wovens, have their chemical and thermal stabilities and their fire resistance improved by application thereto of a polyester of an aromatic dicarboxylic acid, such as terephthalic acid optionally admixed with isophthalic acid, and a halogenated dihydric phenol which may be mixed with up to an equal mole percent of a halogen-free dihydric phenol. The synthetic resinous material may be a crude pre-form wrapped in a sheet of the polyester and formed into final shape with heat and pressure and, optionally, curing. An epoxy resin or polyurethane adhesive may help bond the synthetic resinous material to the polyester sheet. The synthetic resinous body may comprise a polyamide, polycarbonate, polyvinylchloride, polystyrene or polyester.

Abstract: A metallurgical furnace or vessel is provided with a refractory lining consisting of an outer layer of tamped granular ceramic material and an inner layer, which forms a protective sheathing for the outer layer and consists of bricks made of fused lime, fused dolomite, chrome magnesite, or fused magnesia. The tamped layer of ceramic material may consist of fused magnesia or stabilized zirconium oxide or alternatively of granular quartzite, corumdum, mullite or spinel. In the latter case, an intermediate layer is provided between the tamped layer and the inner brick layer to prevent reaction between the bricks and the tamped material. The intermediate layer consists of fused magnesia or stabilized zirconium oxide.
