Title: Improvements in or relating to Beam Balances
Inventor: TJUTIKOVA MARIA IVANOVNA
IPC: G01G3/02
Filed: 1968-01-11
Abstract: 1,195,322. Weighing apparatus. M.I. TJUTIKOVA, B.V. GRAN, E.I. SMIRNOV, O.S. IVANOV and S.A. PODDUBNY. Jan. 11, 1968, No. 1600/68. Heading G1W. A beam balance comprising a beam pivotally mounted on a fulcrum 11 is acted upon by a spring 12 in such a way that when the beam is in balance forces produced by the spring 12 act through the fulcrum and do not affect the balance of the beam whereas when the beam is out of balance the forces produced by the spring 12 tend to increase the deflection of the beam. As shown, the beam which is mounted by elastic pins 11 on a frame 10 in a casing 1, 8 is provided at its ends with scale pans 18. The spring 12 which is connected at its upper end to the beam 9 is connected at its lower end to a lever 13 which is pivotally mounted on the frame 10 and which is connected at its ends by springs 15, 16 to micrometer screws 5, 6 respectively, micrometer screw 5 being calibrated. With no load on the beam the micrometer screw 6 is adjusted to ensure the beam is in balance with the micrometer screw 5 set at zero. When a load is mounted on one scale pan and a counterweight on the other scale pan, the difference in weight, indicated by the resultant tilting of the beam under the influence of the load weight and spring is obtained either directly from the amount of tilt of the beam or indirectly by adjusting the micrometer screw 5 to restore balance and reading off the micrometer screw reading. When the beam is at balance, the balance position or tilt of the beam is indicated by a lamp-lens-mirror arrangement. The spring 12 may be a tension spring arranged so that its ends are above and below the fulcrum, respectively, or a compression spring having both its ends above the fulcrum Fig.4 (not shown).

Title: Improvements in or relating to multi-phase induction motors
IPC: H02P3/24
Filed: 1956-01-17
Abstract: 781,682. Control of induction motors. LANCASHIRE DYNAMO & CRYPTO, Ltd., BUTLER, O. 1., BARTON, T. H., and STERLING, H. Jan. 17, 1956, No. 1630/56. Class 38 (3). [Also in Group XXXV] A three-phase induction motor is braked by the combination of the action of a short-circuited single-phase stator winding D of larger pole-number and the single phase energization of the main stator winding A, B, C. This single-phase energization may be series delta as shown, or parallel delta, or series or parallel star. The main winding pitch is about equal to the pole-pitch during normal running, and its phase-spread is not equal to 120 degrees electrical. The phase terminals are joined AlC2, BlA2 and ClB2 for normal running when contacts 5, 6, 7, 8 are closed, but A1 and C2 are separated and fed with single-phase current through contacts 9, 10 for braking. This induces a six-pole excitation of the stator for braking down to one-third of synchronous speed. The auxiliary winding D is also wound to produce six poles displaced by 90 degrees from the six braking poles. This winding produces braking down to zero speed. Alternatively, the winding D may be a three-phase short-circuited winding displaced 30 degrees from the main winding as shown. Specification 777,278 is referred to.

Title: Improvements in and relating to the manufacture of articles from metallic powders
IPC: B22F3/10
Filed: 1945-01-24
Abstract: A method of making a dense and substantially non-porous article from a mixture of two or more powdered metals, one of which is soluble in another, comprises sintering the mixture, without the prior application of external pressure and without the use of a binder, at a temperature below the melting point of at least one of the metals, but such that a liquid phase is present, that is, such that one metal passes into solution in another.  As applied to the manufacture of a wedge-shaped article from a mixture of copper, nickel and tungsten powders, the mixture is loosely packed in a wedge-shaped mould arranged with its plane of symmetry vertical.  If the mould is of refractory material it may be heated to the full temperature required, that is 1450 DEG  C.  If the mould will not withstand such a temperature, it may be heated to, say, 1000 DEG  C. so that the particles of metal adhere sufficiently to form a coherent body which is then removed from the mould for the final sintering.

Filed: 1936-01-22
Abstract: Arsenobenzene - monosulphoxylates of the formula <FORM:0469324/IV/1> in which R and R<1> represent hydroxyalkyl groups and R<2> stands for an alkyl or hydroxyalkyl group, are prepared by condensing aminobenzene-arsines with aminobenzenearsenoxides and introducing before or after the condensation two hydroxyalkyl radicles into the one amino group by treatment with an alkylene oxide and into the other amino group the formaldehyde-sulphoxylate p  radicle and either an alkyl radicle by means of an alkylating agent or a hydroxyalkyl radicle by treatment with an alkylene oxide.  One of the trivalent arsenic compounds used as starting materials may if desired be prepared in situ by reduction of the corresponding arsonic acid. According to the examples: (1) 3-hydroxy - 4 - (bis - dihydroxypropyl)-aminobenzene-1-arsenoxide is condensed with 3 - methylamino - 4 - hydroxybenzene - 1-arsine and the resulting arsenobenzene treated with sodium formaldehyde-sulphoxylate; (2) 3 - (dihydroxypropyl - hydroxyethyl - amino-4 - hydroxybenzene - 1 - arsenoxide is condensed with the reaction product of 3-methylamino - 4 - hydroxybenzene - arsine and sodium formaldehyde-sulphoxylate; (3) the condensation product of 3-amino-4-hydroxybenzene - 1 - arsenoxide with 3 - dihydroxypropylamino - 4 - hydroxybenzene - 1 - arsine is treated first with sodium formaldehydesulphoxylate and then with a double molecular proportion of glycide to form 3-(bis-dihydroxy propyl) - amino - 4 - hydroxy - 3<1> - dihydroxypropylamino - 4<1> - hydroxyarsenobenzenemonosulphoxylate; (4) a mixture of 3-hydroxy-4 - aminobenzene - 1 - arsenoxide and 3-methylamino - 4 - hydroxybenzene - 1 - arsonic acid is reduced in aqueous solution with hydrosulphite and the product converted into the sulphoxylate; further treatment with ethylene oxide and glycide in succession, using equimolecular proportions of each, produces 3-hydroxy - 4 - (dihydroxypropyl - hydroxyethyl) -amino-3<1>-methylamino-4<1>-hydroxy-arsenobenzene -sulphoxylate.  Arsenoxides.--3 - Hydroxy - 4 - (bis - dihydroxypropyl) - aminobenzene - 1 - arsenoxide, as well as the unsubstituted 4-amino compound, are obtained by reduction of the corresponding arsonic acids with sulphurous acid and potassium iodide. 3-(Dihydroxypropyl - hydroxyethyl) - amino - 4 - hydroxybenzene - 1 - arsenoxide is similarly prepared from the corresponding arsonic acid, which latter is formed by the action on 3-amino-4-hydroxybenzene - 1 - arsonic acid of ethylene oxide and glycide, each in equimolecular proportion.  Arsines.--3 - Methylamino - 4 - hydroxybenzene-1-arsine is obtained by reducing the arsonic acid with zinc dust and hydrochloric acid as described in Specification 11625/11, [Class 2 (iii)].  3-Dihydroxypropylamino - 4-hydroxybenzene-1-arsine is similarly prepared from the corresponding arsonic acid, which is itself produced by reacting 3-amino-4-hydroxybenzene-1-arsonic acid with an equimolecular proportion of glycide.

Title: Improvements in or relating to photographic stripping films
IPC: G03F7/09
Filed: 1958-01-21
Abstract: 835,170. Photographic stripping films. DU PONT DE NEMOURS & CO., E.I. Jan 21, 1958 [Jan. 28, 1957], No. 2086/58. Class 98(2) A stripping film for photogravure has an organic solvent dissoluable hydrophobic film support carrying two layers of gelatine, the layer nearer the support being coated from a predominantly organic solvent solution and the other layer from a predominantly aqueous solution, between it and a water permeable organic colloid silver halide photographic emulsion. The reverse side of the dissoluable support is releasably joined to a strippable hydrophobic film base. The support and base may be of cellulose ester, polyvinyl ester or acetal, polyhexamethylene adipamide or polyethylene terephthalate. In an example the rear of a cellulose acetate film base is waterproofed by coating with a solution of cellulose nitrate in acetone followed by a solution of gelatine in methanol and acetone together with salicylic acid and a further layer of hardened gelatine containing an anti-halation dye. On the front of the film base is coated a dry stripping layer of ethyl cellulose and cellulose nitrate in butyl alcohol and acetone followed by a solution of cellulose nitrate in acetone followed by a solution of soluable gelatine and salicyclic acid in methanol, ethanol and acetone followed by an aqueous solution of soluble gelatine containing small amounts of potassium chloride, saponin, glycerine, ethanol and thymol, followed by an orthochromatically sensitised silver chloro-bromide emulsion containing more soft gelatine than silver halide. After exposure, the film was developed in a developer of specified composition, treated with a solution of sodium carbonate arid fixed with sodium thiosulphate. After the film has been applied to a copper gravure plate, the strippable film base is dry stripped and the dissoluable support removed by successive applications of a mixture of diacetone alcohol and isopropyl alcohol. A resist is then formed by dissolving away all unhardened gelatine with warm water. The soluble gelatine layer adjacent the emulsion may contain an anti halation dye and the gelatine anti halation layer at the rear of the film base may be omitted. The water proofing layer on the film base may be a vinylidene chloride co-polymer. Specification 835,171 is referred to.
