Title: Improvements in and relating to electrical resistors
IPC: H01C17/20
Filed: 1944-05-21
Abstract: 633,686. Electric resistors. PHILIPS LAMPS, Ltd., and HOLMES, T. May 21, 1944, No. 5273. [Class 37] A resistance comprises an insulated tube, e.g. of glass or a ceramic, an internal coating of carbon deposited from a suitable atmosphere, connecting leads inserted in the ends of the tube, and electrically conducting cement securing 'the wires in position and at the same time sealing the tube ends. The carbon coating is produced by electrically heating a tube 2 of glass, ceramic, &c. in a furnace 3, Fig. 1, by a heating winding 4, to a temperature at which pyrolysis or cracking of vaporized hydrocarbons, e.g. methane, ethane, propane, butane or benzene or a mixture thereof introduced through a tube 1, occurs. The hydrocarbons may be introduced into the furnace only when the cracking temperature is reached and, a diluent such as nitrogen may be used. Alternatively, the tube 2 may first be swept out with such an atmosphere, the flow of gas being continued while the tube 2 is heated to cracking temperature. The flow of gas is continued after switching off the furnace until the tube 2 has cooled to avoid deterioration, e.g. by oxidation of the carbon coating, or the tube 2 sealed at one end could be evacuated and heated to the cracking temperature before introduction of the hydrocarbons with or without a diluent the tube later being cooled as above or after evacuation. The hydrocarbons could entirely surround the tube 2, the external coating being removed after cooling. After cooling the tube 2 is divided into short lengths 7, Fig. 2, and wire connecting leads 5 formed at their interior ends to approximate to the interior diameter of the tube 2 are cemented into the tube ends. The leads 5 are first coated with a carbon suspension known under the Registered Trade Mark " Aquadag " or coated by copper spraying or silvering to improve contact. The cement 6 is then applied and preferably consists of a paste of silvered copper suspended in a solution of thermo-setting or other resin or binding material. After insertion of the coated wire ends the resistor is allowed to air-dry for one hour and then baked at 150‹ C. to cure the resin binder. The ends of the resistor may then be covered with an insulating cement and finally the whole resistormay be coated with lacquer to further seal the ends and then colour coded.
Patent GB-373222-A (GB)
Title: Improvements in or relating to the manufacture of rubber compositions
IPC: C08L97/00
Filed: 1931-02-20
Abstract: Rubber compositions containing granular, fibrous or divided materials such as leather fibre, asbestos fibre, wood pulp, wood flour, jute fibre, cotton flock, paper pulp, abrasives and cork are prepared by mixing these materials with granular precipitates composed of rubber and a filling material which has been precipitated in situ by the interaction of two water-soluble reagents.  The admixture may be carried out by first preparing the granular precipitate, and then mixing this with a dispersion of the fibrous &c. materials, or the fibrous &c. dispersion may be mixed with the latex and one soluble reagent, and then the second reagent added to produce the coagulation of the rubber and the precipitation of the filler.  Examples are given of both methods of procedure.  Reagents of the first class are carbonates, sulphates, silicates of the alkali metals or of ammonium, which have normally no coagulating effects upon the rubber.  Reagents of the second class are soluble salts of magnesium, aluminium, calcium, barium, zinc, or sodium silicate if a reagent of the first class is used such as to precipitate silicic acid.  Mixtures of precipitates may be formed, and the reagents may be so chosen than only one soluble product results for two insoluble products. Protective colloids such as glue, gum acacia may be added.  The dispersions may include as well as rubber, those of guttapercha, balata, and artificial dispersions of coagulated rubber, vulcanized rubber, synthetic rubber, waste or reclaim. Concentrates obtained as described in Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], may be used.  The mixtures of rubber and filler are separated and consolidated by filtration.  The shape of the finished article may be determined by the form of the filter surface.

Title: Process for preserving foods
IPC: A23L3/3544
Filed: 1966-02-08
Abstract: Films used for wrapping foodstuffs are made from compositions comprising isomaltol (i.e. 2-hydroxy-3-acetyl furan) and polyethylene, polypropylene, polyvinyl chloride or a copolymer of vinyl chloride and vinylidine chloride, together with conventional plasticizers and stabilizers.ALSO:Foodstuffs are preserved by contacting with a small quantity of isomaltol (i.e. 2-hydroxy-3-acetyl furan) or a non-toxic salt thereof.  The preservative may be mixed with the foodstuff, or as an aqueous solution may be used as a dip for or sprayed on to the foodstuff, or included in a packaging material in which case the foodstuff is protected by the vapour of the preservative.  Such packaging materials include paper which has been soaked in an aqueous solution of isomaltol and films of polyvinyl chloride or polyethylene compositions in which isomaltol has been incorporated during manufacture.  The preservation of strawberries, shredded coconut, chocolate cake (isomaltol being added to the batter before baking), oranges, asparagus, prune juice, raspberries, and a meat containing dog food is exemplified. The preservation of bread by wrapping in isomaltol-containing plastics films is also mentioned.

Title: Improvements in weighing scales
IPC: G01G23/00
Filed: 1924-03-04
Abstract: 233,476. Marks, E. C. R., (Toledo Scale Co.). March 4, 1924. Pendulum-weight apparatus.-In a weighing scale employing a pendulum of the rolling sector type the power sector of the pendulum is adjustably mounted on, and has its outer face curved eccentrically to, the face of the fulcrum sector. As shown, a pendulum 30 is suspended at each side by a flexible band 7 passing round a fulcrum sector 6 which rolls upon a vertical track (not shown). The pull due to the load is applied to a flexible band 15 passing over a power sector 12 and attached to a finger 13 secured to the fulcrum sector. The surface of the power sector 12 is eccentric to the surface of the fulcrum sector in order to produce equal movements of the indicating pointer for equal increments of load, and the power sector may be adjusted by means of screws 22, 23 to bring the sector into correct operation with the band. By this arrangement the zero position of the indicating pointer, actuated by the usual rack 19, is substantially unaffected by adjustment of the power sector upon the fulcrum sector. The screws 22, 23 are connected to the power sector by swivels. Specification 15724/13 is referred to.

Title: Improvements in or relating to dental impression supporting trays
IPC: A61C9/00
Filed: 1936-02-27
Abstract: 460,817. Dental impression trays. ARMSTRONG, J..J. V. (Kalvin, L.) Feb. 27, 1936, No. 5831. [Class 81 (ii)] A dental impression tray comprises a pressed body of sized cellulosic fabric, such as woven fabric or felted or moulded pulp, having a water-absorbent inner surface which does not adhere to the moist plaster, and a waterrepellent outer surface, produced, for example, by a collodion spray. In making the tray, two layers, for example, of three-ply buckram, already united by sizing such as starch, tapioca, glue or dextrin, are soaked, superposed and shaped in a heated die press. The outer surface is then waterproofed. A single heavy ply may alternatively be used. The tray is preferably formed with partition ridges 14, 16 to stiffen it and to weaken the plaster on definite lines to facilitate fracture. Parting fins for excluding plaster from parts of the impression, for example, where teeth are missing, may be disposed in slits in the tray. The fins, of semihard rubber or similar material, may take the form shown in Fig. 6, and are cut from a strip, Fig. 4. Due to the elongation of the web portion 17 when pulled through the slit, and the subsequent contraction, the fin is firmly fixed in position. A fin having a wedge-shaped head 22, for use in the ridges 14, 16 is shown in Fig. 2. The open mesh reinforcement disclosed in Specification 415,264 may be used in combination with the present tray.

Title: 8ª‰-substituted-11ª‰-hydroxysteroids and their preparation
IPC: C07J75/00
Filed: 1963-08-23
Abstract: The invention comprises (1) a process for preparing an 8b  - iminomethyl- or 8b  - formyl-11b -hydroxy steroid wherein an N-acylated 8b , 11b -carboimidic lactone is subjected to reductive fission by the Birch reduction and, when required, the resulting 8b -iminomethyl-11b -hydroxy steroid is treated with an acid to give the corresponding 8b -formyl steroid; and (2) 8b  - iminomethyl - 5a  - 22 - ergostene-3b ,11b  - diol and 3,3:17,17 - bisethylenedioxy-8b  - iminomethyl - 5 - androsten - 11b  - ol and the corresponding 8b -formyl steroids.  The starting material may be of the androstane, pregnane, cholane, cholestane, sitostane, ergostane or spirostane series and may contain free or functionally converted hydroxyl and oxo groups and double bonds. If the reductive fission is effected in the presence of a proton source the 8b -iminomethyl steroid results directly; but when it is effected on an N-alkoxycarbonyl compound in the absence of a proton source an N-alkoxycarbonyl dihydrocarboimidic acid lactone results which is then hydrolysed with an alkali to the required 8-iminomethyl compound.  The N-acylating group may be a lower (i.e. C1- 8) alkanoyl, aroyl, lower alkoxycarbonyl or aryloxy carbonyl group. The acid treatment may be effected with an acid, metal oxide or salt which can release protons or act as a pseudo acid.

Title: Improvements relating to the dressing of fish
IPC: A22C25/16
Filed: 1937-03-01
Abstract: 491,452. Dressing fish. HASLAM, W. H. (Baader, R.) March 1, 1937, No. 6132. [Class 28 (ii)] In a fish-dressing machine wherein the fish is drawn, tail first, past knives which make filleting cuts in it, blade knives are caused to enter these cuts and are moved towards the tail clamp faster than the fish is travelling, so that the cuts are continued right up to the tail. As shown, the invention is applied to a machine as described in Specification 454,496 wherein the fish are gripped at their tails by clamps 100 carried by rotary arms, and are pulled past two pairs of horizontal disc knives which make filleting cuts along the backbone, these pairs being swung away from each other to permit the passage of the tail clamps. At a point beyond the filleting knives, is arranged the supporting and operating means for the blade knives, comprising a shaft 2 rotating continuously in a fixed bracket 1, and carrying freely a member 3 having an arm 4 carrying two blade knives 5, 6 and an arm 7 constituting one arm of a parallel linkage 7, 8, 9, 10. The arm 8 is keyed to the shaft 2 and the pivot 11 between the links 9, 10 carries a roller 12 which runs in a fixed cam slot 13 on the underside of a plate 14 fixed to the bracket 1. The arm 8 is arranged to make one complete revolution between the times of arrival of successive tail clamps, but the cam slot 13 is designed to produce deformation of the parallel linkage 7-10 in such manner that the arm 4, and the knives 5, 6 thereon, are accelerated when they enter the filleting cuts, and move up to the tail clamp 100. The ends of the fillets are then clamped against the flat sides of the knives 5, 6 by pivoted jaws 15, 16 which are interconnected by gearing and are opened, against the action of a spring 20, by a cam track 19 acting on a roller 18. Directly the jaws close, two severing knives 25, 26 move across the flat surfaces of the knives 5, 6 close to the side surfaces of the jaws, the knives 25, 26 being carried by a rod 28 slidable by a rocker 33 pivoted at 31 on the arm 7 and carrying a roller 30 running in the cam slot 13. When the fillets have been severed from the backbone, they are pulled by the jaws 15, 16 along their circular path about the centre shaft 2, and the backbone continues its path with the tail clamp 100. The jaws then open to drop the fillets on to a conveyer 35.
