Title: Process for utilising alloy steel scrap to form steel bodies
IPC: C21C5/56
Filed: 1950-12-22
Abstract: 681,876. Casting composite sheets; casting processes; moulds. DEUTSCHE EDELSTAHLWERKE AKT.-GES. Dec. 22, 1950 [Dec. 23, 1949], No. 31237/50. Class 83 (i). Alloy steel scrap is utilized by melting and casting in a thin layer on a supporting body while in a neutral or reducing atmosphere. The supporting body has an integral or detachable edge wall and may comprise carbon or low alloy steel which has had its surface cleaned, e.g. by pickling, sand blasting or planing, and has been heated to at least 1200‹ C. This produces a clad sheet which can be at once rolled. If a simple sheet is required the body may comprise cold or only slightly heated steel or ceramic or other refractory material preferably coated with mould wash before each pour. The scrap is preferably melted in small quantities by electro-induction. The crucible containing the scrap and one or more supporting bodies may be placed under a hood which is then cleared of air by burning illuminating gas, the scrap is then melted, e.g. by induction, and poured. The supporting bodies may be pre-heated in a furnace or heated while under the hood.

Title: Improvements in apparatus for removing dust and other impurities from air, funnel smoke and other gases especially gases from chemical and electro-chemical factories
IPC: B01D45/14
Filed: 1949-12-06
Abstract: 686,318. Centrifugal separators. LOFTHEIM, T. B. Dec. 6, 1949 [Dec. 10, 1948], No. 31315/49. Class 23. In a dust separator of the centrifugal type comprising a bladed rotor having primary passages communicating with primary outlets for the purified gas at the periphery of the blades, and having at least one secondary outlet for the dustbearing gas, each blade has at least one secondary opening for receiving the dust from a primary passage and delivering it outwardly through a secondary passage to a secondary outlet, the secondary opening or openings being so arranged that it or they deliver the dust-bearing gas to the secondary passage at different distances from the axis of rotation. In Fig. 2 the space between a pair of blades 1 constitutes a primary passage 9 and primary outlet 19, and the secondary passages are constituted by tubes 3 disposed at the peripheral edges of the blades. The tubes are inclined to the axis of rotation and each communicates with a primary passage through a correspondingly inclined secondary opening 2. The tubes are closed at their ends nearer to the axis of rotation and communicate at their other ends with the secondary outlets. Fig. 3 shows a separator of the kind described in Specification 582,480, referred to, comprising scrollshaped blades mounted on a rotor body 11. Each scroll discharges purified gas through an axially-disposed primary outlet 19, and dust-laden gas through a series of secondary openings 12 communicating with a secondary outlet 15 via a secondary passage 14. In Fig. 5 the spaces between the blades 17 constitute the primary passage 9 and primary outlets 19, while secondary openings 18 communicate via a secondary passage 20 with a secondary outlet 24. An additional dust outlet 23, formed between a stationary wall 21 and a rotary wall 22 of lesser diameter, prevents, it is stated, separated dust from returning to the primary outlets.

Title: Production of articles composed of fibrous reinforced resin materials
IPC: B29C70/52
Filed: 1964-08-04
Abstract: 1,073,973. Moulding fibre-resin tubes. UNIVERSAL MOULDED FIBER GLASS CORPORATION. Aug. 4, 1964 [Aug. 2, 1963], No. 31372/64. Heading B5A. [Also in Divisions B8 and F2] Fibre-reinforced resin tubes are formed by applying a liquid thermosetting resin e.g. a polyester, to the upper end of a fixed core, allowing the resin to flow down the core under gravity whilst applying the reinforcement, and finally shaping and curing the tube thus formed by pulling it over the mandrel, through a forming chamber having a heating zone. As shown in Fig. 1 the resin is applied at 36 and first longitudinal rovings 58 and then helically wound fibrous sheets are applied by stations carried by plates 46 and 47 respectively. Two sets of helical rovings 75 of opposite hand are then applied from reels 75a mounted on rotary table 73 carried by plates 48 and 49. Further helically wound sheets are applied followed by a further set of longitudinal rovings and the whole is covered by longitudinal fibre sheets 89 which may or may not overlap. The tube P thus formed is drawn by a co-operating caterpillar track mechanism through a forming passage A formed between an outer double-walled chamber and the core. The double-walled chamber (see Fig. 13, not shown) comprises an upper cooling zone and a lower heating and curing zone, the entrance to the passage being flared at (26a) so that the reinforcement is properly impregnated and any excess resin is expelled, which excess is recirculated along with additional fresh resin for application to the core. The upper reaches of the core may be cooled to prevent premature hardening of the resin.

Abstract: 760,026. Induction generators; supply systems depending on variable speed generators. LEISCHNER, G. Nov. 17, 1953 [Nov. 19, 1952], No. 31801/53. Classes 35 and 38 (4). A self-excited induction generator having a separate exciting winding connected to condensers is provided with a further winding premagnetizing the active iron crosswise to the main flux so as to reduce its permeability to control the output. As shown in Fig. 1 for a core with semi-closed main slots 2 accommodating the output and exciting windings, the saturating flux 5 is provided by coils in slots 4 in the teeth. Modified arrangements are shown in which the slots 4 are of different shapes, e.g. pear-shaped so as to fit into tapered teeth. In machines where the stack of laminations are enclosed within a solid iron casing which carries part of the flux, the slots 4 may be partly in the laminated and partly in the solid cores. In a modified form of stator comprising a series of U-shaped iron bundles, as shown in Fig. 5, the saturating windings are situated in channels 7 intersecting the bights of the cores to produce an axial saturating flux. A circuit arrangement for the generator is shown in Fig. 6, in which the delta-connected exciting windings 1 are energized by star-connected condensers 2, while the centre-tapped output windings 3 feed the load 11 and battery 10 through rectifiers 6. The saturating windings 4 are fed through non-linear resistors 8 and adjusting rheostat 9 to control the output voltage. Current compounding is achieved through a further saturating winding 5 in series with the load 11. In a modified form the saturating winding is fed directly from a separate A.C. coil through non-linear resistors so as to produce a saturating flux having a harmonic frequency.
