Title: Improvements in or relating to fish frying and like ranges
IPC: A47J37/12
Filed: 1931-11-07
Abstract: 379,913. Frying-ranges. RUSSOM, T. H. and RUSSOM, C. W., (trading as DAVY MACHINE CO.), 8, Admiral Street, Dewsbury Road, Leeds. Nov. 7, 1931, No. 30868. [Class 126.] In frying-ranges in which fumes from the pan are withdrawn by a fan 4, they are drawn past or in contact with the fish racks 2 in order to keep the contents warm. In the construction shown, the fumes may pass around the sides, bottom, top, and back of the fish rack before passing over a baffle 6 to the fan. A sump 13 is provided for the grease and fat. The fan 4 consists of two in tandem, the second fan being in a duct 14 through which it supplies a forced draught below the grate. The range is also provided with a centrally-arranged chip-box (not shown), which is kept warm by an air jacket supplied with air heated in a vertical duct passing through the smoke-box. The air from the jacket passes subsequently into the spaces around the fish racks, and is withdrawn, together with the fumes, by the fans.

Title: Preparation of polyvinyl fluoride film
IPC: C08J5/18
Filed: 1971-07-01
Abstract: 1312394 Polyvinylfluoride films DYNAMIT NOBEL AG 1 July 1971 [2 July 1970] 30981/71 Heading B5B Polyvinylfluoride films are made by preparing a homogeneous sheet from polyvinylfluoride having a K-value of from 50 to 100, preferably from 60 to 70, and calendering the sheet into a film. The polyvinylfluoride must contain no plasticizer, swelling agent or solvent, but stabilizers, antioxidants and lubricants can be present. In examples the sheet is produced by calendering at 180‹ C. on a two-roll stand and is converted to a film by calendering on a four-roll stand at temperatures up to 217‹ C. The edges of the films may be trimmed to give a uniform sheet and the trimmings returned to the calender rolls.

Abstract: 160,000. Perl, A. H. F. Dec. 12, 1919. Hooks, closed.- In a modification of the curtain clip described in Specification 133,875, [Class 44, Fastenings, Lock &c.], the hook parts 3, 4 are arranged to contact near their upper ends 7, 8, which are curved outwardly to facilitate the insertion of a curtain ring, rod, or the like. The parts 10, 11, are also curved outwardly, to facilitate turning of the ring or hook into position, after insertion of the ring. The projecting members 12, 13 are pivoted together, by an eyelet 9, and may be formed with rectilineal upper edges, to coact with the shouldered parts 14, 16 and prevent the two parts of the clip from being moved beyond their closed position.

Title: Improvements in or relating to clutches
IPC: F16H3/44
Filed: 1958-09-30
Abstract: 844,133. Variable-speed gearing. GENDRE, L. Sept. 30, 1958 [Sept. 30, 1957], No. 31213/58. Class 80 (2). Gearing for disconnecting or connecting at a variable ratio the drive from a shaft 6 to a shaft 7 comprises bevel gears 1, 2 on the shafts 6, 7, respectively, which are engaged by planet bevel 3, 4 on a free carrier 5. The bevels 3, 4 are provided with rollers 10 on pins 11 which co-operate with an epicycloidal surface 9 on a member 8 rotating with but axially slidable on the driven shaft 7. The member 8 may be urged axially by a spring 13 under control of an axially adjustable collar 12. When the spring is not acting there is no resistance to the rotation of the planet bevels as the rollers 10 roll freely along the surface 9 and no drive is transmitted to the gear 2 and driven shaft 7. As the spring pressure is applied to member 8, rotation of the planets is resisted to a greater or less extent and a drive is correspondingly transmitted to the driven shaft, the speed of which will depend upon the resisting torque and compression of the spring 13. In a modified arrangement the member 8 is resiliently adjustable circumferentially relative to the driven shaft to apply the loading to the planets.

Title: Method for separating naphthalenic hydrocarbons for petroleum fractions
IPC: C10C1/12
Filed: 1963-08-09
Abstract: Naphthalenes are separated from petroleum fractions by reacting with an alkali metal in the presence of an aliphatic mono-ether having a methoxy group and/or a polyether derived from an aliphatic polyhydric alcohol in which all hydroxy groups are etherified to form an alkali metal compound of the naphthalene which is separated and decomposed to recover the naphthalene.  The feed may boil in the range 375-600 DEG  F. and is reacted with alkali metal dispersed in an inert solvent which may be the ether using, if desired, a dispersing aid. The ether preferably forms at least 50% wt. of the reaction medium and reaction is effected at below 0 DEG  C., e.g. -20 DEG  to -50 DEG C.  The metal compound is precipitated by adding a C4-C10 hydrocarbon, filtered off and decomposed by heating to 50 DEG  C. at 100-200 mm. Hg. or by adding a large quantity of light hydrocarbon. The alkali metal and ether are recovered and re-used.

Title: Process for the manufacture of ª‰:ª‰:ª‰-trichloro-ª‡-hydroxy ethyl phosphonic acid dialkyl esters and/or dichloro-vinyl phosphoric acid dialkyl esters
IPC: C07F9/09
Filed: 1957-10-11
Abstract: Chloral or a chloral alcoholate is reacted with phosphorus trichloride and an alcohol in such a ratio that in the reaction product obtained no chlorine atoms remain attached to phosphorus atoms.  Hydrochloric acid which is liberated during the reaction is immediately removed from the reaction mixture, the manner of its removal affecting the nature of the product. When it is removed by evaporation under reduced pressure or is neutralized with sodium hydroxide solution the process yields predominantly a b .b .b .-trichloro-a -hydroxyethyl phosphonic acid dialkyl ester. When the liberated hydrochloric acid is removed by means of aniline, pyridine, or similar acid-binding agent the product consists predominantly of a dichloro-vinyl phosphoric acid dialkyl ester which is formed by elimination of HCl from the initially produced phosphonic ester. In an example, 148 parts of chloral, 150 parts of chlorobenzene, and 46 parts of anhydrous ethanol are added dropwise to a mixture of 138 parts of phosphorus trichloride and 250 parts of chlorobenzene at 0-10 DEG  C.  The mixture is stirred for several hours at 30 DEG  C. and then 320 parts of ethanol are added.  When the addition is complete the hydrochloric acid is rapidly removed under reduced pressure, and then the solvent is distilled off.  The residue is predominantly b .b .b  - trichloro - a  - hydroxyethyl-phosphonic acid diethyl ester.  In another example, chloral and phosphorus trichloride are run from separate vessels into a mixture of pyridine, propanol, and chlorobenzene at 0-10 DEG C.  After stirring for several hours, the pyridine hydrochloride is filtered off and the solvent is removed by distillation under reduced pressure.  The product consists mainly of b .b -dichloro-vinyl-phosphoric acid dipropyl ester.  The products may be used as active ingredients in pesticidal preparations and veterinary medicaments.
