The dyes are obtained by acylation of compounds of formula <FORM:1009794/C4-C5/2> in molar ratio 1 : n with acylating agents which contain the reactive group as above.  The acylation is generally carried out at temperatures between - 10 DEG  and +30 DEG C. with cooling, the liberated mineral acid being neutralized with alkali agents, additions of organic solvents, e.g. benzene, toluene or dimethyl sulphonide may also be employed.  The products are salted out with sodium or potassium chloride. The acylating agents include b -chloro and bromo-propionyl chloride, and the following propionyl chloride derivatives, b -phenylsulphonyl, b -methylsulphonyl, b -ethylsulphonyl, and b -phenoxy, also b -chloroacrylolyl chloride, acrylolyl chloride, b -chlorocrotonyl chloride, chlorazine, chloro-azole, trichloro, 1,3,5- or 1,2,4-triazines especially cyanuric chloride, dichloro triazines and trichloro pyridazines, pyrimidines and pyrazines, tetrachloropyridazines, pyrimidines, pyrazines and dichloro pyridazones.  If the heterocyclic acyl radical introduced has more than one halogen atom then further reactions may be carried out with compounds containing hydroxyl, amino, mercapto, and thiocyanato groups provided at least one reactive chlorine remains.  The diphenylsulphone radical may contain other groups as well as the sulphonic acid group. The starting materials of Formula II may be prepared, for example, by reaction of 1-amino-4-bromoanthraquinone-2-sulphonic acid or -2,5, -2,6, -2,7, -2,8 disulphonic acids with diamino-diphenylsulphone-sulphonic acids.

Filed: 1975-10-29
Abstract: 1498715 Ion pumps; ionization manometers VARIAN ASSOCIATES Inc 29 Oct 1975 [30 Oct 1974] 44616/75 Heading H1D A gas sensing apparatus comprises a sensing unit 40, a narrow constriction and a pump 60, the gas passing into the sensor and through the constriction to the pump, the gas conductance of the constriction 50 being much smaller than the pumping speed of the pump. The gas concentration in the sensor, for any given rate of entry, is then practically independent of variation in the pumping speed. The gas detected may, e.g. be hydrogen, entering, e.g. from an atmosphere via a Pd diaphragm 20 or after a water leak from solution in liquid Na via a Ni membrane. The pump 60 may be a sputterion pump with cold Ti (or alloy) or Ta cathode 64, the sensor 40 having a similar construction with an inactive, i.e. non-pumping cathode 44, e.g. of stainless steel. The total anode current, mainly from the sensor, is monitored 90 to measure gas concentration. In both chambers a magnetic field parallel to the axes of tubular anodes 42, 62 increases the electron path length. Owing to the reduction of overall pumping rate to a figure close to the conductance of the tube or aperture constriction 50, for a given gas influx the pressure is raised in chamber 40, increasing the sensitivity. Multiple cells in each chamber, and multiple sensing chambers, possibly detecting different gases, connected via separate constrictions to one pump, may be introduced.

Abstract: 964,539. Laminating. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 10, 1962 [Dec. 13, 1961 (2)], Nos. 44671/61 and 44672/61. Heading B5N. A laminate is formed by applying particles of an organic thermoplastic material to the surface of a sheet material, melting the particles by e.g. a radiant heater to form discrete globules, and then pressing a preformed film, or a heat softened freshly extruded film, of an organic thermoplastic material on to the treated surface and chilling the resulting bonded laminate. The preformed or extruded film may be, for example polythene, polypropylene, polyvinylchloride or polyethylene terephthalate (which may be biaxially oriented) and is in the range 0.0005 inch to 0.002 inch thick. The thermoplastic powder is preferably of the same material as the film and may be a polymer thereof with a lower melting point. The sheet material may be a rough fabric, e.g. hessian, or a fine fabric, a fibrous sheet of jute or hemp, felt, paper, metal foil, or a high softening point thermoplastics film. Two suitable laminating processes are illustrated in the Figures accompanying the Provisional Specifications. In the Figure accompanying Provisional Specification 44671/61 (not shown), powder is applied to a sheet 3 by a perforated drum 4 and the powder melted by passing the sheet around a drum 1 under radiant heaters 5, the thus treated sheet being then laminated to a preformed film 7 by rolls 8, 9. In the Figure accompanying Provisional Specification 44672/61 (not shown), powder is applied to the sheet material and heated to form globules, the thus treated sheet being then bonded to a freshly extruded film between two rolls, one of which is cooled. Specification 777,584 also is referred to.

Title: Token operated device
IPC: D06F34/30
Filed: 1961-12-14
Abstract: 919,688. Coin-freed apparatus. MAYTAG CO. Dec. 14, 1961 [Jan. 19, 1961], No. 44792/61. Class 27. A token-operated device such as a washing' machine is operated by a token T having conductive portions S and non-conductive portions R arranged in predetermined pattern indistinguishable from each other to an observer and electrical contact members a-g in the device engage the token at predetermined locations to complete a circuit through the conductive portions for operating the device. The token T has a thermoplastic base on which are printed the portions S of conductive material and the portions R of nonconductive material, such as printing ink, the latter being arranged to disguise the conductive portion. On the token being inserted in the token receiver, the portion S completes a circuit between contacts b and c and also closes a switch 25 for a heater element which invalidates the token by deforming it and, in deforming, it shrinks so that the switch 25 opens again. A guide 95 at the rear of the receiver deflects the used token downwardly to a receptacle when another is inserted. As applied to a washing-machine, the making of the circuit through contacts b and c and through switch 25 supplies current to a resistance-capacity circuit and after a time delay of a few seconds the charge on the capacitor builds up sufficiently to fire a neon gas tube. The illumination of the gas tube reduces the resistance of a photo-electric cell to a low level and a relay is closed to complete a circuit for energizing the automatic timing control of the washing-machine. After the timer motor of the washing-machine has operated for a small part of its cycle, it closes contacts to complete the heating element circuit through the switch 25 but the machine continues its cycle, when the switch 25 opens again, under the control of its timer motor which continues to be energized through a holding circuit. To prevent operation on insertion of a counterfeit token or other object, the contacts a and d-g are linked to a line 90 and if the object connects contact b with any of the linked contacts the capacitor is shorted and cannot fire the gas tube. Even if b and c only are connected for a short time, the relay circuit will not be energized unless switch 25 is also closed.
