Title: Improvements in or relating to wire coiling machines
Inventor: BRIDEN HORACE
IPC: B21F3/04
Filed: 1959-03-12
Abstract: 894,013. Coiling. GENERAL ELECTRIC CO. Ltd. March 14, 1960 [March 12, 1959], No. 8611/59. Class 83 (4). A machine for coiling a wire on a mandrel to form a filament is characterized in that the wire is guided to the mandrel during coiling at an angle thereto and after coiling the wire guide is moved so that the wire end extends parallel to the mandrel. Wire 4 from a reel 3 passes through a tube 5 to be held by jaws 21 on a support 7 on carriage 6. The carriage is then moved towards a chuck 13, the jaws 22 on which are then closed to grip the end of the wire, a lever 12 carrying one of the jaws 21 is then pivoted away from an anvil 11 carrying the other jaw 21 so that the wire passes around a peg 17 on the lever 12 and extends therefrom towards a mandrel 14 at an angle of approximately 80 degrees to the mandrel axis. The mandrel 14 is then advanced through a hole in one of the jaws 22 of the chuck 13 to and through a hole 15 in the anvil 11. The chuck 13 is then rotated and the carriage 6 moved away therefrom so that the wire passes over the peg 17 and a rounded edge on the anvil 11 on to the mandrel 14 to be coiled thereon. During coiling an electric current is passed through the wire from the peg 17 to the mandrel 14 to set the turns. At the completion of the coiling the chuck 13 is stopped and the lever 12 is swung back into its original position to bend the wire back against the anvil 11 until it lies parallel to the mandrel 14. The lever 12 is then swung back slightly to release the wire from the jaws 21 and the carriage 6 is retracted to cause the mandrel 14. to be withdrawn from the hole 15 in the anvil 11. The lever 12 then grips the wire again, Fig. 6, and a pair of cutters 23 sever the wire between the coil 24 and the anvil 11. The mandrel 14 is then withdrawn and the jaws 22 opened to drop the coil. To ensure that the ends of the coil are in alignment with one another or are offset by a specified amount around the circumference of the coil compensating means are provided to rotate the coiling head support 7 through a predetermined and adjustable angle during coiling. Said means comprises, Fig. 7, a rotatable arm 30 driven by the mechanism which moves the carriage 6 and linked to a curved lever 25 pivoted at 27. The lever 27 moves, through adjustable link means 28, 31, an arm 32 in a shaft 33 geared to a wheel 10 which turns the coiling head support 7.

Title: A process for the culture of bacteria for a mixed auto-vaccine
IPC: A61K39/02
Filed: 1930-03-20
Abstract: Auto-vaccines are prepared by growing micro-organisms taken from the patient on a medium containing a concentrated solution obtained from vegetable substances rich in sugar and containing fructose, and a vegetable thickening agent, such as agar-agar, at a temperature corresponding to the body temperature of the patient.  The culture period varies from 2-20 hours.  The culture medium used is preferably that containing expressed banana juice, described in Specification 313,514, [Class 81 (i), Disinfecting &c.].  The micro-organisms may be obtained, according to the particular disease, from the faeces, sputum, tonsils, vagina or other part of the body.  In cases where the germ relationships normal to the particular disease are disturbed the part from which the micro-organisms are to be taken may be re-stocked with the missing organisms by treatment with a culture thereof which has been weakened, but not killed, by heat treatment, before the germs for the preparation of the vaccine are taken.  Fecal germs are obtained from a filtered physiological sodium chloride solution of faeces and are grown on a banana-agar plate and the germs so obtained are then grown on banana-agar plates and a similar plate containing also sterile human blood.  The cultures are then separately killed and mixed for use in a vaccine.  In gonorrhaea, pus from the urethra is first inoculated on a plate containing also white of egg and the vaccine is prepared by cultivating the germs so obtained on plates free from white of egg.  In certain forms of tuberculosis, empyema, and asthma a vaccine from fecal germs is first injected to produce expectoration and a vaccine is then prepared from the sputum.  A mixed vaccine is also used which contains both sputum germs and fecal germs.  The Specification contains instructions for preparing vaccines for treating a large number of specified diseases.
Patent GB-346550-A (GB)
Title: Improvements in the manufacture and production of polymerisation products
IPC: C08G65/04
Filed: 1930-03-20
Abstract: Vaporous alkylene oxides are polymerized by passage over catalysts at elevated temperatures.  Alkaline catalysts, such as caustic potash, caustic soda and the oxides or hydroxides of the other alkali metals are suitable for the preparation of highly polymerized wax-like products, which may be liquid or solid, while acid-reacting substances, such as sodium bisulphate, aluminium sulphate, or mixtures of these with small amounts of sulphuric acid or with diluents such as sodium sulphate, or acid phosphates, are suitable catalysts for the preparation of dioxane and its homologues.  The temperatures of working lie between 40 DEG -200 DEG  C., the range 100-160 DEG  C. being preferred.  In the examples, (1) ethylene oxide vapour is led over anhydrous caustic soda at the rate of 0,1-0,4 gram per second per litre of catalyst, the catalyst being situated in a vertical iron tube which is maintained at 120-130 DEG  C., this temperature regulation being effected by means of a jacket containing a suitable liquid, e.g. ethylene glycol.  Cooling in the reaction chamber is also aided by the use of excess of ethylene oxide, which passes out at the lower end of the tube and is returned to the process.  The liquid formed is collected in a closed receiver, where it solidifies to a waxy or horn-like mass.  This may be freed from enclosed caustic potash by dissolving it in benzene, filtering and evaporating. (2) Anhydrous sodium bisulphate is substituted for the caustic soda of the previous example, and the ethylene oxide passed over it, the vapours condensed and returned to the process.  After about 24 hours, the condensate is fractionated, yielding unchanged ethylene oxide, dioxane and a small amount of acetaldehyde ethylene acetal <FORM:0346550/IV/1> (3) Propylene oxide is passed over anhydrous potassium hydroxide as in example (1).  The product is a viscous liquid which is insoluble in water but soluble in most organic solvents, including alcohol, ether, and aromatic hydrocarbons.  (4) Propylene oxide is passed over a catalyst consisting of 1 part of sodium bisulphate mixed with 3 parts of anhydrous sodium sulphate. From the issuing vapours, a crude dimethyl dioxane consisting mainly of 2,5 dimethyl dioxane is condensed, distilled in vacuo under reduced pressure, then fractionally distilled.

Abstract: 492,761. Embossing - machines; feeding and delivering sheets. KENRICK & JEFFERSON, Ltd., and GIFFORD, R. D. April 1, 1937, No. 9248. [Classes 100 (i) and 100 (ii)] A device for feeding sheets to and delivering them from the operating dies of a relief stamping machine of the kind set forth in Specifications 174,436 and 310,072, [both in Class 100 (ii)], in which the engraved plate is mounted in a reciprocating carriage face downwards and coacts with a vertically reciprocating ram or plunger is constructed with a reciprocating slide carrying a pair of grippers 19a, 20a which are so operated that, as one pair 19a takes a sheet from its registered position against rising front stops 32, the other pair 20a takes the embossed sheet and carries it to a delivery device E. The sheets are separated and fed from a pile by known means, and they are registered against the front steps and also acted upon by side-registering devices 37 of the pusher-type, and are held in registered position by a reciprocating member 47 all operated by cam and lever mechanism from a cam-shaft 27 which is driven by chain-and-sprocket gearing from a shaft 29 of the embossing-machine. The slide 7 is reciprocated by means of lever- and-link mechanism 18, 17, 17a, 16, 14, 13, 12 from an oscillating shaft 11 which also operates the means for reciprocating the die. The lever 12 is coupled to the shaft 11 in such a way that it can be disconnected when it is desired to convert the machine to a hand-feeding one. The slide 7 moves in a guide 8 upon which is mounted a cam-shaft 27 fitted with a number of cams for operating levers 25, 26, and 23, 24 (not shown), which respectively act to close and open the grippers 19a, 20a by depressing end raising rods 19b, 20b for turning square cams which move the gripper arms to open position and permit them to be moved by spring action to closed position. In embossing position the sheet is held to the bed plate 42 by a reciprocating member 48, and the bed plate is formed with a gap to permit of the raising of the ram 10, and it is supported by bars 43. To prevent the sheets from bending upwardly ribbons of steel 45 supported by brackets 46 are arranged above the bed. The ram 10 is normally raised by straightening toggles 53, and a hand-operated pawl 58 is provided to cause a finger 49 to engage a shoulder 52a on an arm 52 associated with the toggles and so prevent actuation of the ram. In the event of a failure in the supply of sheets a reciprocating set of needles 33, which are normally moved forwards over the sheets when engaged by the front stops 32, are arrested by depressions 62 on the machine bed, and by means of a cam-actuated lever 64 and a cable 65 passing over pulleys the finger 44 is operated to stop the impression by holding the toggles in their inactive position.
