Abstract: 996,197. Automatic control of arc welding. AIR REDUCTION CO. Inc. Sept. 15, 1961 [Sept. 22, 1960], No. 33158/61. Heading G3R. A regulated power supply system provided with negative feedback devices is modified to avoid instability in the system due to time delays in the response of the system to demands for changes in the power output thereof, the system being particularly applicable to those using magnetic amplifiers having an inherent dead time or delay in the response of the output to changes in the input. A load 82 such as an arc welder, is supplied with power by way of a magnetic amplifier 300 and is controlled by a reference signal input 134, this reference being fixed or varying as desired. A negative feedback 104 dependent upon the load current is derived by means of a transformer 83 and a measuring device 100, the feedback being taken to an amplifier 304 where it is differentially compared with the reference signal 134, the error being fed to a voltage summing device 308 and, by way of an amplifier 306 to a first analogue circuit 172, 174 and thereafter to a second analogue circuit 314. The time constant of the analogue circuit 172, 174 represents the time constant of the equivalent resistance R of the current measuring means 83, 100 together with the inductance L of the smoothing inductor 84 whilst that of the analogue circuit 314 is related to the difference of the arc resistance RL and the equivalent resistance R. A further feedback 110 representing the load voltage is fed to the summing device 308 by way of an attenuator 310 and the output of the device 308 is taken to the magnetic amplifier 300 to effect control thereof. Thus transient feedbacks are fed into the system during the dead time of the magnetic amplifier 300 from the analogue circuits, that from the circuit 172,174 by way of a transformer 146 and that from the circuit 314 by way of a delay circuit 220 and a transformer 114. Specification 996,196 is referred to.

Title: Synthetic resinous compositions and articles made therefrom
IPC: C08K3/08
Filed: 1954-11-22
Abstract: A coherent, self-supporting body comprises a heat-cured silicone resin or a nylon and aluminium powder filler in amount of from 50 to 95 per cent by weight of the total composition.  In making the body, a mixture of the resin and aluminium is preferably made by making a paste of each before mixing, e.g. the silicone is mixed with xylene and the aluminium powder is mixed with white spirit and stearic acid. The resulting mixture may then be cured or otherwise formed in situ or partially cured (in the case of the silicone) and then subjected to stamping, pressing, &c.  The silicone composition may be heated to above 350 DEG  C. to partially decompose the resin to give a self-supporting composition form-stable at a temperature above the meting point of aluminium.  In examples, a paste of A1 powder and white spirit was blended with an aromatic solvent solution of a silicone resin, spread (1) in a metal tray, or (2) on thick copper sheet, and heated at 150 DEG  C. for 2 hours, at 400 DEG  C. for 1 hour and finally at 900 DEG  C.; (3) an aluminium paste and a nylon were mixed with white spirit and the mixture was warmed and stirred until it set, heated slowly to 275 DEG  C. and the resulting liquid was poured into a metal tray and some into a tubular mould, and finally cooled to yield products which were bendable and machinable. Uses.-For making gaskets, sealing washers, bearings, bearing liners, cylinder liners, exhaust manifolds, and gas turbine tail pipes, and for jointing compounds for steam and chemical plant joints.

Title: Improvements in organic fibrous sheets, methods for preparing the same and applications thereof
IPC: D04H1/655
Filed: 1959-10-08
Abstract: 928,893. Fibrous sheets. NORMANLIN, S. a.r.L., R. MOREL, and C. DE JARNY. Oct. 8, 1959 [Oct. 9, 1958; March 17, 1959; July 16, 1959], No. 34199/59. Class 42 (2). A method of making sheets of non-woven organic vegetable or animal fibres, e.g. flax fibres, adapted to be used in forming resin-bonded laminates, or as reinforcement for plaster of Paris or cement building elements comprises forming a layer of unorientated interengaging fibres, so as to leave interstices through which a binder can readily pass, introducing therein a solution of an impregnating and adhesive coagulable organic colloid followed by a coagulant, to form a non-adhesive product inert to synthetic resins or their cross-linking agents, compressing the impregnated sheets by rolling, and drying and finishing them. The treatment of the invention protects the fibres against further impregnation by sealing them prior to their introduction into a compound structure; the . fibres thereby retain their natural properties and are enabled to exert the maximum reinforcing effect upon incorporation in a compound structure. Specified impregnants are solutions of casein (coagulable by formaldehyde), or of gelatine or an alginate (coagulable by aluminium acetate or alum). As shown, organic animal or vegetable fibres in bulk formation, 1, are disintegrated at 2 and dispersed inside a chamber 3 where they are collected by a roller 4 subjected to suction at 5 and formed into a sheet 6 which passes off the roller 4 on to a conveyer belt 7 formed of stainless metal gauze. The fibrous sheet is thereby conveyed into a chamber 8 where it is impregnated with an atomized solution of casein from an atomizer 9. Thence the sheet enters a chamber 10 where an aqueous solution of formaldehyde is projected upon it from an atomizer 11, whereby the adhesive is coagulated, after which the sheet passes between pressure rollers 12, 13 and thence by a conveyer belt 15 through an oven 16 where the sheet is dried and the coagulation completed. Thence the sheet passes through a vat 17 containing material for neutralizing any contained acidic or alkaline material, over driving rollers 19, through a vat 18 containing running water and through an oven 21 for final drying. The finished sheet 22 emerging from the oven is then calendered between heated rollers 23, 24 and is trimmed in width by disc shearers 25. The fibres of the product may be waterproofed by treatment with a diisocyanate, e.g. stilbene diisocyanate, which may react with OH groups in the fibres or with such a diisocyanate together with a polyhydroxy ester. Specification 642,890 is referred to.

Filed: 1972-07-21
Abstract: 1339095 Semi-conductor devices RCA CORPORATION 21 July 1972 [21 Oct 1971] 34292/72 Heading H1K Semi-conductor components such as IGFET 62 and diode 75 are formed in thin semi-conductor layers 52, 54, 56 deposited on to an insulating region 22 which abuts a semi-conductor island 18 containing a further component, such as bipolar transistor 28, there being metallic inter-connections between the various components. In the Si structure shown the insulating region 22 is SiO 2  formed by selective oxidation completely through an N-type epitaxial layre on a P-type substrate 12. A recess may be  etched half-way through the epitaxial layer prior to selective oxidation in order that the insulation 22 may be flush with the remaining semi-conductor surface, but this is not essential. The NPN transistor 28 is formed in two adjacent islands 16, 18 connected by a buried As or Sbdoped n<SP>+</SP> layer 44 forming a connection between the collector region 34 and the collector contact 49. The layers 52, 54, 56 are left after etching a polycrystalline Si layer deposited on to the SiO 2  region 22. The various regions in the components in the layers 52, 54, 56 are diffused simultaneously with regions in the transistor 28, diffusion occurring more rapidly through the polycrystalline material than into the monocrystalline islands. The layer 56 forms a crossunder beneath Al track 82<SP>1</SP>, isolation being obtained by a SiO 2  layer 42. Reference is also made to the possibility of the layers 52, 54, 56 being monocrystalline, deposited epitaxially on to a monocrystalline alumina layer formed, in turn, by deposition on to the semi-conductor substrate 10.
