Patent GB-898789-A (GB)
Title: A method and means for drying textile webs
Inventor: MURPHY JAMES RICHARD
IPC: F26B13/10
Filed: 1957-09-28
Abstract: 898,789. Coating webs. FAN SYSTEMS Ltd. Dec. 29, 1958 [Sept. 28, 1957], No. 30453/57. Class 140. A method of drying textile webs, e.g. in woven, knitted or felted form, which have been coated on one side, comprises drawing the web, coated side downwards, over a convex perforated support 7, 8 and blowing heated air against the coated side through the apertures. The method is directed to drying carpet material coated on one side with starch, synthetic plastic material, latex or rubber by a brush 4. A fan 11 delivers air, heated at 18, through conduits 10, 13 to the enclosed spaces behind the supports 7, 8 respectively, the air being forced through the carpet for recirculation by the fan 11. Heated air from the conduit 13 may preheat the carpet at 16 and a fan 20 may deliver cooling air to a chamber at the top of the support 8 for forcing through the carpet. The curved support may be provided by one or more driven or idler cylinders, the apertures being blanked off where not contacted by the carpet. Where the coating covers the interstices in the carpet, the heated air is forced against the coated side, the carpet riding on a film of air over the supports. Various modifications are mentioned. The space beneath the supports may have one or more partitions transverse to the carpet to provide a series of chambers one or more of which may be under pressure and the rest under suction, air passing through the carpet and then through the support or to enable different pressures or temperatures or air velocities to be employed at different stages in the drying, or may have one or more longitudinal partitions, the chambers so formed having separate fans, heaters, or dampers, so allowing carpet material of different widths to be dried. Where heated air is blown through the carpet before reaching the support, the support may be concave to reduce friction. The perforations may have spring-actuated flaps or ball valves which are opened by the carpet in passing over the supports, and the support may be divided and the parts bridged by a travelling wire mesh or apertured support through which the air is blown in one direction or in opposite directions at different points.

Filed: 1939-11-24
Abstract: 536,538. Directive wireless signalling. RADIO TRANSMISSION EQUIPMENT, Ltd., and BAILEY, C. E. G. Nov. 24, 1939, No. 30759. [Class 40 (v)] The gain of an amplifier is maintained constant by a locally derived checking signal of constant amplitude which is amplified simultaneously with the received signal, the checking signal output being separated and used to control the gain of the amplifier to maintain this output constant and hence the gain of the amplifier constant with respect to the received signal. Fig. 2 shows a direction finder of known type in which two loops L1, L2 at right angles feed two identical multi-stage transformer-coupled amplifiers V1 ... V3, V<SP>1</SP>1 ... V<SP>1</SP>3 the outputs of which are connected to the pairs of deflecting plates of a cathode ray tube CRT. A constant intensity source CS of say 50 cycles is applied to the valves by low-frequency transformers TR1 ... TR3, TR<SP>1</SP>1 ... TR<SP>1</SP>3. The lowfrequency output appears at TR4, TR<SP>1</SP>4 the secondaries of which are connected in opposition so that the resultant output is applied to a ring de-modulator D1 ... D4 excited from CS through a transformer S. The output appears at the junctions D1, D4, D2, D3 in the form of a D.C. bias for valves V1, V<SP>1</SP>1, the magnitude of which depends on the degree of unbalance and the sign on the direction of unbalance of the amplifiers thus keeping the gain equal and constant. An arrangement is also described for maintaining constant the gain of a single amplifier to which is applied a checking signal of constant intensity, the rectified output of which is used to control the gain, Fig. 1 (not shown). Reference has been directed by the Comptroller to Specfication 528,061.

Title: Production of aluminium and aluminium/silicon alloys
IPC: C22B21/00
Filed: 1964-08-04
Abstract: Oxidic ores comprising Al2O3 and SiO2 are heated in a furnace with a carbonaceous reducing agent and from 15-50% by weight, based on the Al2O3 and SiO2, of an intermetallic of Al and Si with Fe and/or Ti which is at least 75% chemically saturated with Al and/or Si, to give a molten raw alloy of Al and Si which is then tapped from the furnace.  A portion of the Fe and/or Ti may be replaced by Mn and/or Cr but this replacement should preferably not exceed 10% of the total intermetallic composition.  After tapping the raw alloy is cooled to about 600 DEG C. to leave the alloy as a liquid, the solid phase being the intermetallic complexes any excess elementary Si and any impurities.  The solid phase may be crushed and screened to recover the elementary silicon and any of the Al/Si alloy trapped on cooling which may be returned to an earlier process step. Commercially pure aluminium may be made from the Al/Si alloy by treating it with a metallic solvent (Zn, Pb or Hg) to give a solid portion and a liquid portion from which the aluminium may be recovered by conventional techniques.
