Patent GB-867790-A (GB)
Title: Method and apparatus for producing hypochlorite of soda in an electrolytic cell
IPC: C02F1/467
Filed: 1958-04-03
Abstract: 867,790. Electrolysis. FERRIS, D. E. April 3, 1958, No. 10830/58. Class 41. A method of producing sodium hypochlorite comprises continuously flowing a stream of an aqueous solution of sodium chloride in one direction through a hollow tubular cathode 10, then in the opposite direction between the outer surface of the cathode 10 and the inner surface of a surrounding tubular anode 5, and then in the original direction between the outer surface of the anode 5 and the inner surface of a surrounding tubular cathode casing 6. A portion of water to be purified passing through a main 15 is by-passed at 16 to the pipe 10, which is cathodic by virtue of its connection to the casing 6, and flows through the cell to an outlet pipe 19 to rejoin the main stream at 70. The brine content of the water to be treated may be increased, e.g. in the case of fresh water, by by-passing water from the pipe 16 through a pot 20 containing salt by means of an apertured pipe 21, the water rejoining the pipe 16 by means of an apertured pipe 26. The apparatus may be provided with wheels and a handle, the current being supplied by a rectifier controlled by a rheostat, and the pipes 16, 19 having coupling members for attachment to the main. In a modification in which the apparatus works under pressure, the salt pot includes a filter of gravel and sand and a pipe connection between the outlet pipe 19 and the pot enables water to circulate between the cell and pot when the delivery of water through pipe 19 to the main is interrupted by closing a valve, the pipe connection having a pressure-responsive valve. In this modifica. tion, all the water from the pipe 16 passes through the pot and filter. Adjustment of valves and of the rheostat enables the acidity of the brine, and hence its bacteriacidal properties, to be regulated.

Title: Improvements in and relating to dial switches
IPC: H04M1/677
Filed: 1932-04-15
Abstract: 389,661. Impulse transmitters. FULD & CO. TELEPHON-UND TELEGRAPHENWERKE AKT.-GES., H., 136, Mainzerlandstrasse, Frankfort-on-Main, Germany. April 15, 1932, No. 10836. Convention date, Oct. 22, 1931. Addition to 383,166. Drawings to Specification. [Class 40 (iv).] The dial transmitter described in the parent Specification for mechanically preventing the emission of impulses when a predetermined one or two-digit member is dialled, is modified so that the emission is prevented both for one or more single digits and one or more multidigit numbers. As described, emission is prevented when the initial digits 9 or 00 are dialled and this is effected by a modification of the contours of the cams described in the parent Specification.. Further, when any initial digit is dialled, one of the cams remains off-normal to close a circuit for giving an indication that the transmitter is in use.

Title: Injectable iron compositions
IPC: C07H23/00
Filed: 1965-03-15
Abstract: A complex of ferric iron and monosaccharide phosphate ester is prepared by reacting a colloidal aqueous solution of ferric hydroxide and an aqueous solution of an alkali metal salt of the said ester, in such proportions that the atomic ratio of iron to phosphorus does not exceed 10.7:1.  The complex may be precipitated from the resulting solution by addition of about 0.5 volumes of ethanol, the complex containing iron and phosphorus in the said atomic ratio and any excess ester remaining in solution.  Also described is a preparation, from glucose-1-phosphate, of the potassium salt using an anion exchange resin.  The monosaccharide esters may be fructose-1-phosphate or glucose-1-phosphate.  The aqueous solution of the complex is for use in pharmaceutical compositions (see Division A5).ALSO:Intravenously administrable iron compositions comprise an aqueous solution of the complex formed by reacting a colloidal aqueous solution of ferric hydroxide with an aqueous solution of an alkali metal salt of a monosaccharide phosphate ester, in such proportions that the atomic ratio of iron to phosphorus does not exceed 10.7:1.  The esters may be fructose-1-phosphate or glucose-1-phosphate preferably as sodium or potassium salts.  The ferric hydroxide solution is prepared in known manner by adding ammonia solution to ferric chloride solution and dialysing against water; it should contain about 5% Fe2O3.  The reaction is preferably performed by adding the ferric hydroxide solution to the sugar phosphate solution, rather than vice-versa, to avoid forming and redissolving a precipitate.  The ratio of iron to phosphorus is preferably below 10.7:1, so that unreacted sugar phosphate is present in the composition for its stabilising effect.  The final solution may be further stabilised by boiling after preparation, and also by addition thereto of sodium citrate.

Patent GB-771144-A (GB)
Title: Improvements in or relating to the purification of zirconium tetrachloride
IPC: C01G25/04
Filed: 1955-04-15
Abstract: Zirconium and hafnium tetrachlorides are purified by heating a fused mixture containing the impure tetrachlorides and a minor amount of at least one alkali metal chloride above the temperature at which the tetrachlorides vaporize and thereafter condensing the evolved purified tetrachlorides.  Zirconium tetrachloride and attendant hafnium tetrachloride can thus be freed from metal and metalloid impurities and the content of zirconium oxy chloride decreased.  The preferred fused starting mixture contains 88 per cent crude zirconium tetrachloride and 12 per cent potassium chloride which mixture melts at about 215 DEG C.  Zirconium tetrachloride sublimes at about 331 DEG C. at atmospheric pressure. According to examples (1) a fused mixture of the zirconium tetrachloride and potassium chloride was heated to 500 DEG C. and the zirconium tetrachloride collected as a crystalline solid.  The impurities in the zirconium tetrachloride were reduced from 3000 parts of metallic impurities per million to 193 parts per million. Further examples relate to distillation at 600 and 450 DEG C., and to the use of different alkali metal chlorides and proportions thereof and to the use of mixtures of alkali metal and alkaline earth metal chlorides.  A further example (9) describes the re-employment of the fused salt residue after carrying out the zirconium tetrachloride distillation, which residue contains 27.5 parts of zirconium tetrachloride and 12 parts of potassium chloride. To such a residue further crude zirconium chloride is added and the mixture melted and purified zirconium tetrachloride recovered.  The crude zirconium tetrachloride can be added to the fused salt residue after the latter has been cooled and pulverized, or while it is in liquid state.  Alternatively the fused salt composition may be employed to scrub impurities from the crude tetrachloride.  Thus a mixture containing 88 per cent zirconium tetrachloride and 12 per cent potassium chloride may be melted and crude zirconium tetrachloride introduced at about the same rate as purified zirconium tetrachloride is vaporized from the molten salt bath.

Abstract: 1,123,166. Casting process. ANTECH Ltd. 15 March, 1966, No. 11216/66. Heading B5A. Articles are cast from or are impregnated, e.g. electrical coils, with synthetic thermoplastic or thermosetting resins, e.g. polyesters, polyurethanes, silicone and epoxy resins, within a mould M provided on a table in a chamber B, which chamber B is raised into sealing contact with an upper resin-containing chamber A whereby, after degassing of both chambers through valves V1 and V2, connected to a vacuum pump and with degassing of the resin chamber controlled by admission of air through valve V6 to prevent foaming, the mould M is raised upon the table to seal around an outlet valve 10 from the resin chamber which valve is then opened, together with a valve V3 which admits a predetermined quantity of air to the resin chamber to raise the pressure therein as resin fills the mould. After a short dwell air is admitted to both chambers via ganged decay valves V4 and adjustable throttles Q, whereby the resin chamber pressure is maintained greater than that in the mould chamber as the pressure in both chambers rises to atmospheric at a controlled rate. The resin chamber may be provided with a paddle-mixer mounted on the shaft of the resin outlet valve member 10 and the apparatus may be provided with heating and cooling coils whereby the apparatus or the resin may be heated. The chambers are sealed by ring seals and are looked together by pressure applied by electrical, hydraulic, pneumatic or mechanical means which means may also effect raising and lowering of the mould table and operation of the valves. The moulds may be made of aluminium, polymethylmethacrylate or polypropylene. The operation of the apparatus is preferably centrally controlled and the correct sequence of operation is maintained by interlock mechanisms. A single or multiple cavity mould may be used or two separate moulds supplied through a suitable head adjacent the resin outlet valve. The mould chamber is sealed at the top and base by ring seals 6 and 8 which are kept in engagement by inward pressure in the chambers. Resin is cleaned from chamber A by force or solvent.

Filed: 1966-03-16
Abstract: 1,097,042. Sewing machines. E. BECKER and K. NOTZ, [trading as QUICK-ROTAN BECKER & CO.], March 16, 1966 [March 23, 1965], No. 11454/66. Heading D1G. [Also in Division F2] An arrangement for stopping a sewing machine in the needle raised or lowered position is controlled by an electromagnetic clutch/ brake mechanism, the current supply to the solenoids of which is governed by a pair of switching transistors. As shown the shaft 7 may be driven at high speed by an electric motor 1 which can be coupled directly to an intermediate shaft 4 by friction clutch discs 2, 3, or driven at a low speed by an auxiliary belt drive 16, 17. The disc 3 is operable by a bell crank 24 connected by a chain 22 to an operating pedal 21 which is depressed to engage the clutch. Belt 16 drives a pulley 15 which may be coupled to a shaft 72 carrying a worm 11 driving a disc 9 freely mounted on shaft 4, the shaft 12 carrying a clutch member 13 which may be coupled to pulley 15 by a solenoid 14 to establish the auxiliary drive, or to a fixed brake member 19 by a solenoid 20. The driven shaft 7 carries a slip ring interrupter 25 comprising three rings 26, 27, 28 of which rings 26, 28 have insulated segments 29, 30 at diametrically opposite positions to effect stopping of the shaft at the needle raised or lowered position. The electric control circuit, Fig. 2, includes a pair of transistors 34, 35 connected to solenoids 14, 20 respectively, and rectifiers 44, 45 arranged in parallel with the solenoids to act as by-pass anodes. A third transistor 48 controlled by transistor 35 prevents transistor 34 from conducting when an interrupter brush is in contact with a conductive portion of a slip ring. Either one of the interrupter rings 26, 28 may be brought into circuit by a selector switch 49, according to whether raised or lowered needle is desired. For this to be effected pedal 21 is released to break the main drive by disengaging clutch discs 2, 3, the slow auxiliary drive 16, 17 then being operative through discs 3, 9 and the speed of shaft 7 then falls until at a particular cut-off value a capacitor 38 is unable to supply sufficient current during the passage of segment 29 or 30 over its associated brush, when transistors 34, 48 block and transistor 35 conducts, to energise brake solenoid 20 and thus lock worm 11 and cause disc 3 to be held braked against the stationary disc 9.

Abstract: 126,213. Kirk, G. July 13, 1918. Burglar and like alarms.-An alarm which can be employed with systems of either the open or closed circuit type is constructed with a switch member operated by a magnetic relay and combined with a lock which is used to re-set the device after the alarm is sounded, and which is also employed for rendering the device inoperative during the day. As applied to a closed-circuit type of apparatus, the closed contacts X are arranged in a circuit comprising a battery P, switch R, and an electro-magnet L which, when the current is flowing, attracts an armature M and breaks contact between a bar Z, and a contact N. When one of the contacts X is opened, the current ceases to flow in the electro-magnet L, and the contacts M, N join and current flows from a battery S through bar Z, contacts M, N to an electro-magnet Y, the return circuit to battery S being completed through a contact G, lock D, and a switch F comprising spring members held in contact by an insulated member H on a lever B held in the position shown by a pivoted armature A. When the electro-magnet Y is energized as above described, the armature A releases the lever B, and the contacts F are separated, and the circuit from the battery S to the bell K is completed through the arm B, bolt E, and contact G. The bell K continues to ring until the arm B is raised by the bolt E, thereby breaking the circuit at G: the arm B is then caused to be reengaged by the armature A, and when the bolt D is returned to the position shown, the alarm is ready to operate again. When applied also to open-contact systems, the normally open contacts are connected to the contacts N, Z, so that when any of the contacts is closed the alarm is given as described. The lock D is contained in a panel or the like.
