Title: Improvements connected with a.c. commutator motors
IPC: H02K27/12
Filed: 1941-02-05
Abstract: 546,185. Alternating current commutator machines. SCHWARZ, B. Feb. 5, 1941, No. 1531. [Class 35] A polyphase commutator machine has a wound stator and a rotor with a commutator and commutator winding C, the commutator being fed from the supply through a continuously rotating brush-gear D and the rotor winding C or a separately wound polyphase winding on the rotor being connected through slip rings SS to the stator winding ST. The speed of the rotating field is increased or decreased by the revolution of the brushes according as they revolve in the same or opposite direction as the field and the motor runs synchronously at twice the speed of the rotating field. The brush gear has slip-rings B' for connection to the supply through a constant phase variable voltage transformer or induction regulator T. A variable or constantspeed A.C. or D.C. motor MA drives the brushes through gears G which may be of variable ratio. Induction starting may be obtained by shortcircuiting the stator winding directly or through a starting resistance. When operated as a generator the power delivered can be varied without varying the speed of the prime-mover. In a modification the functions of rotor and stator are interchanged, a commutator winding on the stator being fed through a stationary commutator and rotating brushes while the phase-wound rotor winding is connected to the stator winding through slip-rings.

Title: Processes and apparatus for the treatment of water with ozone
IPC: C02F1/78
Filed: 1960-01-15
Abstract: 930,110. Aerating water with ozone. THE CITY OF DUSSELDORF REPRESENTED BY THE OBERSTADTDIRECTOR OF DUSSELDORF. Jan. 15, 1960 [Jan. 16, 1959], No. 1571/60. Class 14 (1). [Also in Group I] In a process for treating water with ozone, a small portion of the water is separated and intimately mixed with ozone, the mixture then being injected under pressure into the remaining larger portion of water before the water is led to the bottom of a contact vessel from which it flows continuously through an outlet at the top of the vessel, so that substantially all the ozone is dissolved before the water leaves the contact vessel. The main part of the water is supplied to the contact vessel 40 through a feed pipe 41, pumps 42 and an inverted U-shaped inlet pipe 43 the downstream arm 44 of which is deeply immersed in the vessel 40. The remaining small portion of the water, previously separated from the main feed pipe 41, is supplied through a pressure pipe 45 to a water jet pump 47 connected to an ozone-air mixture supply pipe 46, the pump 47 supplying an intimate mixture of ozone and water under pressure to a water ring compressor 48. The compressor 48 causes further mixing and feeds the mixture through pipe 49 to the upstream arm 50 of the pipe 43 in counter-current to the rest of the water from the feed pipe 41. The resulting turbulence and the subsequent long path of flow promotes thorough mixing of the ozone-water mixture with the rest of the water. The water from the arm 44 is led to the bottom of the contact vessel 40 from which it flows through an outlet 52 controlled by a valve 53 into a storage tank 54. The pump 47 is provided with a needle valve so that the amount of ozone mixed with the water can be controlled.

Title: Electric discharge lamps
IPC: H01J61/35
Filed: 1974-01-14
Abstract: 1441471 Metal vapour discharge lamps GENERAL ELECTRIC CO Ltd 14 Jan 1975 [14 Jan 1974] 01724/74 Heading H1D A discharge lamp having a fused silica envelope and a filling including mercury, a scandium halide and possibly another metal halide (neither halide being a fluoride) and the pressure being greater than one atmosphere, has on the interior surface of the envelope a coating of at least one of the oxides of scandium, yttrium, lanthanum and the rare earth metals, the coating at least partially penetrating the surface of the silica. The oxide can be applied by forming a metal film which is then oxidized in situ prior to filling the envelope. The metal film in such a process can result from decomposition of a halide of the metal, e.g. a monohalide produced by passing a higher halide over particles of the metal, the monohalide being introduced, possibly with hydrogen, at a temperature of 900‹ to 1100‹ C., the metal film so formed being heated at 1000‹ to 1200‹ C. in an oxidizing atmosphere such as air, oxygen or inert gas with oxygen or water vapour. A typical filling is 20 mg. sodium iodide, 10 mg. scandium tri-iodide, 12 mg. mercury and argon at 20 torr at room temperature in an envelope having a diameter of 18 mm. and an arc length of 90 mm. To form the oxide coating such a lamp requires 4 mg. scandium and 12 mg. scandium tri-iodide.

Title: A process for converting insoluble substances into a state of aqueous solution or suspension
Filed: 1927-01-20
Abstract: 264,860. I. G. Farbenindustrie Akt.- Ges. Jan. 20, 1926, [Convention date]. Sizes.-Aqueous solutions or dispersions of solid substances which are normally insoluble or only slightly soluble in water are obtained by dissolving or suspending the substances in waterinsoluble organic solvents or mixtures thereof, and mixing the solutions or suspensions with water in the presence of aromatic sulphonic acids or their salts, particularly those which possess high wetting properties, sodium sulphanilate being excepted. Suitable sulphonic acids are the alkyl, aryl, aralkyl, or hydroaryl derivatives of aromatic sulphonic acids or of aromatic halogen-, oxy-, nitro-, carboxy-, or amino-sulphonic acids, the alkyl &c. radicals being situated in the nucleus and/or in the substituent radical or serving to link up several aromatic radicals. Specifically, suitable sulphonic acids.or salts are (1) the products resulting from the action of alcohols such as isopropyl alcohol, iso- or n-butyl alcohol, or cyclohexanol, on naphthalene sulphonic acids, and the condensation products of these products with aldehydes; (2) the products obtainable by the action of alkyl or aralkyl chlorides, such as benzyl chloride, on naphthol ethers, such as #-naphthol propyl, butyl, or amyl ether, and subsequent sulphonation: (3) sulphonic acids of fatty acid arylides or the salts of such acids, such as sodium stearoanilidosulphonate; and (4) diamylnaphthylamine sulphonic acid, benzylsulphanilic acid, butylsulphanilic acid, butylaminonaphthalene sulphonic acid, and diethylmetanilic acid. The action of the sulphonic acids or salts may be assisted by addition of protective colloids, such as glue, gelatine, or gum arabic, or of other dispersing agents, such as sulphite cellulose waste liquor, soaps, or turkey red oil. The substances which may be dissolved or dispersed include natural or artificial resins and cellulose esters and ethers, and the solutions or dispersions may be used in finishing or dressing wool, cotton, and artificial silk, &c. According to specific examples, (1) a solution of colophony in benzine is stirred with a solution of sodium isopropylnaphthalene sulphonate to which glue has been added, and the mass is diluted with water to give a stable emulsion of the resin, suitable for finishing or dressing fabrics: and (2) a lacquer, such as copal varnish, which has been coloured with a water-insoluble dye; is treated with an aqueous solution of a mixture of sodium butylnaphthalene sulphonate and glue, whereby a coloured emulsion suitable for finishing or dressing is obtained. The Specification, as open to inspection under Sect. 91 (3) (a), refers to the use of aliphatic sulphonic acids or their salts. This subject-matter does not appear in the Specification as accepted.
Patent GB-567523-A (GB)
Title: Coating compositions
IPC: C09D5/34
Filed: 1943-02-03
Abstract: A surfacing composition comprises a solid granular ethyl cellulose of ethoxy content between 46.8 per cent and 48.5 per cent, dispersed in a vehicle in which the ethyl cellulose is substantially insoluble at normal temperature and which comprises a drying or semi-drying oil or oil-modified alkyd resin, but is free from volatile solvent.  The composition may be subjected to a baking treatment directly after it has been applied to an article, or a top-coating composition may be applied and the two compositions may be baked together.  The baking may be carried out at 275-350 DEG  F. and for a sufficient length of time to cause fusion of the ethyl cellulose particles and partial solution in the remainder of the composition.  The viscosity of the ethyl cellulose as determined at 25 DEG  C. on a 5 per cent solution in a solvent composed of 80 parts toluene and 20 parts denatured ethyl alcohol, by weight, may be from 7 to 100 centipoises.  The ethyl cellulose should be present in an amount of 6 to 10 per cent of the total composition.  The liquid vehicle may be a drying or semi-drying oil or an alkyd resin modified with such an oil.  It should be substantially free from volatile matter so as to avoid swelling and blistering on baking.  The vehicle may have an acid number of 4-10 and a viscosity of 9-17 poises.  The oil-modified alkyd resin may be one which has been modified with a synthetic drying oil or synthetic drying oil acid, with or without monobasic acids or natural resins.  In examples, ethyl cellulose grains are mixed with soya bean or linseed oil-modified glyceryl phthalate, dehydrated castor oil or heat-bodied linseed oil, and barytes, whiting, lithopone, talc, or titanium dioxide, to form a white putty-like composition.  In other examples, ethyl cellulose grains are mixed with heat-bodied linseed oil or soya bean oil and lithopone and barytes.  Other pigments which may be used are zinc oxide, antimony oxide, white lead, blanc fixe, silica, china clay, powdered slate, asbestine, red iron oxide, metal chromates, cyanides, sulphides, phosphates, selenides, molybdates, phthalocyanines, and organic dyes.  The top-coat may be of the lacquer or enamel type.  In an example, the top-coat composition comprises titanium dioxide, zinc oxide, soya bean oil-modified glyceryl phthalate, dehydrated castor oil-modified glyceryl phthalate, urea-formaldehyde-monohydric alcohol resin, petroleum naphtha, butyl alcohol and xylol.  In another example, the top-coat composition comprises a mixture of glyceryl phthalate condensation products modified respectively with 52 per cent linseed oil, 40 per cent linseed oil, 46 per cent linseed and chinawood oil, together with chinawood oil-modified phenol-formaldehyde resin, iron oxide, ferrite yellow, bone black, titanium dioxide, antimony oxide, diatomaceous earth, silica, cresylic acid, manganese naphthenate and petroleum naphtha.

Abstract: 575,035. Superposed telephony and telegraphy. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Feb. 4, 1944, No. 2078. [Class 40 (iv)] [Also in Group XL] In a system in which a telegraph or other channel is superimposed on a telephone line, a band of a width not exceeding 300 cycles within the range 500-1800 cycles and preferably including 1500 cycles is allocated to the telegraph channel, this band being excluded from the telephone channel. In such a system, the narrow-band filters employed at the telegraph receiver produce a drag effect on the received signals which necessitates a precise adjustment of the reception level to ensure that the drag does not affect the telegraph relay. Fig. 5 shows a self-adjusting circuit in which the amplifier 4 and amplifier-detector 5 are controlled by negative feed-back from the diode portions of the valve 5 through rectifiercondenser circuits 11; 12 and 17, 18. The condensers charge quickly during a signal and discharge slowly on its cessation on account of the rectifiers, thus providing sufficient hangover to cover the drag period. The circuit 17, 18 has a longer time-constant than 11, 12 and is intended to deal with signals that are only slightly above the proper level.
