Title: Improvements in and relating to electric switches of the liquid-brake extinguishing chamber type
IPC: H01H33/96
Filed: 1938-08-20
Abstract: 502,940. Liquid - blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 20, 1938, No. 24562. Convention date, Aug. 20, 1937. [Class 38 (v)] A liquid - immersed circuit-breaker has two or more pairs of cooperating stationary and movable contacts arranged electrically in parallel to separate in a common extinguishing chamber within which is provided a differential piston adapted, on movement by the pressure produced by the switching arc or arcs, to produce a flow of extinguishing liquid across the arc or arcs, the movable contacts being moved simultaneously and separable from their co-operating fixed contacts simultaneously or successively. As shown, four movable contacts 1-4, cooperate with fixed contacts 5-8, located in a common pressure chamber 9 on hollow supports vented at 14, 15 to permit pressure generated by the arc or arcs to be transmitted to the lower side of a differential piston 10 which is raised against the action of a spring 11 to produce a flow of liquid across the arcs. Subsequently, the liquid is also forced through the hollow movable contacts 1-4 and by way of lateral apertures therein into zones 12, 13 formed by spaced walls 9<1> having staggered apertures therein, this how being stopped as the apertures pass the plates 9<1>, thus producing pulses in the liquid flow whereby the arcs are extinguished. By a relative displacement of the movable contacts in their mountings, successive separation of the individual switch contacts is obtained, in which case only the last pair of contacts to separate act as a high power switch.

Title: Improvements in or relating to the printing of cellulose textile fabrics
IPC: D06P1/22
Filed: 1948-09-20
Abstract: Cellulosic textile fabrics are printed with an aqueous printing paste comprising thermosetting resin-forming materials and a vat dyestuff in the form of its free acid leuco compound or free acid ester of the leuco compound, and in the presence of an acidic catalyst.  The printed fabric may then be passed through a pressure mechanical finishing machine, e.g. a friction calender, schreiner or embossing calender, at a temperature of 200 DEG  to 400 DEG  F. and if necessary, heated to polymerize the resin-forming materials.  A coloured lustrous pattern on a white dull background is obtained. Resin-forming ingredients specified are melamine-formaldehyde, phenol-formaldehyde, urea-formaldehyde, dicyandiamide-formaldehyde, urea-glyoxal, and mixtures of melamine-formaldehyde and urea-formaldehyde.  The thermosetting resin may also serve as the printing gum when using, for example, polyvinyl alcohol-formaldehyde, methyl cellulose-glyoxal or starch-formaldehyde.  The free leuco or leuco ester derivative of the vat dyestuff is made by adding an acid, e.g. formic, acetic, lactic or sulphuric acid to the reduced vat dye or to the ester of the leuco vat dye until the solution is neutral or slightly acid. The printing paste may contain a lubricant such as a sulphonated vegetable, petroleum or animal oil, polymerized ethylene oxide, lecithin, fatty chain modified melamine resins, emulsions of oils or waxes such as castor oil, Japan wax or Carnauba wax, tetra-alkyl ammonium chloride, trialkyl benzyl ammonium chloride, stearamidomethyl pyridinium chloride, or stearyl-oxymethyl pyridinium chloride.  Before subjecting the printed material to the action of the friction calenders or the like, it is dried so that the printed portions contain from 5 to 15 per cent of moisture above the normal moisture content of the fabric.  The treated fabric is preferably given a final washing treatment.  The treated fabric may be subjected to further treatments, e.g. treatment with cellulose swelling agents to produce lustrous coloured patterns on a sheer organdy fabric.

Abstract: 1,143,732. Glass fibre manufacture. UNITED STATES GYPSUM CO. 2 June, 1966 [7 June, 1965], No. 24717/66. Heading C1M. Apparatus for making glass fibres comprises a centrifugal rotor surrounded by a burner with a combustion chamber and inlets of truncated conical form fed by burner nozzles spaced from the inlets or with air holes to permit the induction of air, the burner discharging across the rotor and a further chamber discharging gaseous blasts co-directionally with the combustion chamber to attenuate the fibres. The stream of molten glass 25 is fed to the inner surface of a rotor 2 mounted on a shaft 4 at a slight angle to the horizontal, and its wall is formed with a large number of perforations 3 through which the glass is forced by centrifugal action. The rotor is heated by combustion products issuing from an annular port 20 of a combustion chamber 6 surrounding the rotor. A mixture of gas and insufficient oxidant for complete combustion is fed from a manifold 12 adjustably mounted relatively to the combustion chamber so as to leave a gap 16 between burners 11 and the entrances to the combustion chamber to permit the induction of air to complete the combustion. Steam under pressure is supplied to a chamber 22 and issues from a slot 24 perpendicularly to the direction of movement of the fibres to effect further attenuation. A modified form of the apparatus is described.

Title: Improvements in warp machines
Inventor: TURNBULL WILLIAM GREENWELL
IPC: D04B27/00
Filed: 1950-10-10
Abstract: 733,772. Setting-off warps. RUNKNAGAL, R., and PICOTEX, Ltd. Jan. 10, 1952 [Oct. 10, 1950], No. 24770/50. Class 142(2). [Also in Group VIII] Warp threads are fed from a beam 6, rotated by means including a clutch capable of slipping and comprising co-axial driving and driven members which rotate at the same speed when permitted to do so ; and the threads pass 6 a region of intermittent utilisation over a bar 7 which is displaceable in one direction upon increase in warp pressure on it, to release a brake and so permit rotation of the beam and in the reverse direction, upon decrease in the pressure, to engage the brake and arrest rotation of the supply, causing the clutch to slip. The clutch may be a multi-plate friction clutch 9, or an electromagnetic clutch, to the driven member of which a brake drum 10 is connected directly, or through gearing 23, 123, Fig. 1. Normally, brake shoes 11a, 11b hold the drum stationary, but, as warp tension increases, bar 7 is pulled down and, through linkwork and jaws 20, rocks levers 16, 17 to release it.

Title: Improvements in or relating to an electric tracer control device for machine tools
IPC: B23Q35/32
Filed: 1948-09-22
Abstract: 671,465. Electric control systems. MASCHINENFABRIK HEID AKT.-GES.. Sept. 22, 1948. [April 17, 1944] No. 24821/48. Class 40 (i). [Also in Group XXII] An electrically-operated copying machine tool, such as a lathe, planing or milling machine, particularly for machining crankshaft webs, has a pivoted tracer 2 operating switches that control magnetic clutches in the tool feed drive, the magnetic clutches and the switches being fitted in a single electric circuit, without intermediate relays, and a low voltage, up to a maximum of 40 volts, being supplied to this circuit. This low voltage reduces burning of the switch contacts, and the operating time of the clutches, although increased by the lowering of the voltage from the usual value, is stated to be less than the total time required by both a relay and a clutch. The operating time of the clutch may be further reduced by fitting a resistance such as 19, in series with the operating coils of each clutch, thus reducing the voltage drop across the coil to, for example, 8 volts from 15 volts applied to the circuit and thereby reducing the time of rise of current intensity. The tracer 2b is pivoted at 2a and engages a conical recess 3 in the pivoted switch lever 4, contact between the two being maintained by a compressed spring 4b. Coils 9 and 11 control clutches giving movement of the tool to and from the work and a third coil 10 controls a clutch giving movement at right angles to the to or from movement. When the tracer is out of contact with the templet 1, the contact 5-5a is made and coil 9 is energized to move the tool towards the work and the tracer towards the templet.. When the tracer and templet engage, lever 4 is rotated and the contacts 5a-5b are made but contact 5 remains engaged with contact 5a under the action of a spring (not shown). The clutch controlled by coils 9 and 10 operate simultaneously and a resultant inclined movement towards the work is given to the tool. If the lever 4 is further displaced by the contour of the templet, contact 5, prevented from further movement by a stop, is disengaged from contact 5a so that only clutch coil 10 is energized and the tool moves at right angles to the to and from movement. Still further displacement of the tracer will cause the lever 8 to pivot and, firstly, contact 6 will be made while contact 7 will follow contact 7a under the action of a spring (not shown), giving inclined movement of the tool away from the work, until it meets a stop and then only contact 6 will be made, when the tool moves perpendicularly away from the work.

Abstract: 1,042,566. Tandem axle suspensions. STANLEY STEEL CO. Ltd. June 16, 1964 [June 18, 1963], No. 24833/64. Heading B7D. In a motor vehicle or trailer supported by tandem or multiple axles remote from the steerable axle of the vehicle or the pivotal connection of the trailer to a tractor, inclined radius rods 25, 26 produce a turning of the axles 1, 2 in the required steering direction upon endwise movement of the axles under the thrust produced thereon by the turning action of the vehicle. The radius rods 25, 26 are inclined inwardly from their connection to the axles as shown if the rods are connected to frame 12 forwardly of the axles, or may be inclined outwardly if connected to the frame rearwardly to the axles. To permit the necessary limited sideways movement of the axles, the radius rods 25, 26 are formed at each end with holes which taper from each end (Fig. 3, not shown) to allow rotation of the rods on pivot pins 27, 2d, 30, 31, and springs 34 clamped to the axles slidably engage brackets 11, 22 and an equalizing yoke 15 having sockets 10, 14, 20, 21 wide enough to permit sideways displacement of the springs. If the vehicle has three adjacent axles, the centre axle need not provide for a steering action.

Title: Improvements in or relating to stirring or scraping apparatus for use in tanks for clarifying liquids and for other purposes
IPC: B01D21/06
Filed: 1932-09-07
Abstract: 408,303. Gravity separation apparatus. STOKES, R. 0., Adelaide House, King William Street, London. Sept. 7, 1932, No. 24950. [Class 46.] In a thickener, clarifier or the like having stirring or scraping mechanism revolving in a tank containing the suspension or mixture to be treated, the stirring or scraping mechanism is supported solely on a track 14 round the edge of the tank by means of carriages C of which one or more wheels are electrically driven, the electric supply being taken through slip rings mounted centrally on the stirring or scraping mechanism. Fig. 1 shows a clarifier comprising a tank 1 having an inverted conical base and which is fitted along an arc of its periphery with a feed launder 2 from which the liquid to be clarified passes into the tank through inlet openings 3. The clarified liquid is discharged over weir boards 4 on an opposite arc of the tank periphery into an overflow launder 5. The scraping mechanism comprises a framework 7 having three equally spaced arms the ends of which are supported on the carriages C. The lower parts of the arms have oblique scraping blades 8 which move the deposited solids towards a conical depression 9 at the centre of base and from which the deposited solids are discharged through a pipe 10. One of the carriages C is a driving carriage and comprises two double flanged wheels driven from an electric motor mounted on the carriage ; the electric supply is carried by leads 40 along the arm at the end of which the driving carriage is mounted and connected at the other end to slip rings on the top of a mast 24 at the centre of the scraping mechanism, the slip rings contacting with brushes connected to the former supply outside the tank. The other carriages are trailers serving merely to support the scraping mechanism. In the clarifier shown in Fig. 7 the weir board 4 forming the end of the discharge launder 5 extends all the way round the tank and the liquid to be clarified is fed by a launder 26 to a well 25 at the centre of the tank. The invention may also be applied to the square tanks described in Specification 248,679, [Class 111]. An underspeed alarm may be fitted to a trailing carriage. The alarm shown in Fig. 8 comprises a star wheel 29 fitted to one of the trailing wheels 16 and adapted to periodically raise an arm 30, a dashpot 31 to retard the fall of the arm and a push button switch 37 closing the circuit to a bell or signal lamp &c., actuated by the arm when it falls. To guard against failure of the alarm if a stoppage should take place while the arm 30 is supported by a point of the star wheel 29 the star wheel and arm are duplicated, the second star wheel 38 having its points staggered in relation to the wheel 29. The alarm shown in Fig. 9 comprises a gear pump 42 driven from a trailing wheel, a plunger 46, which permits a small amount of leakage and is adapted to be raised by the discharge from the gear pump, and a spring arm 48 operating a switch on the fall of the plunger.

IPC: H03K23/82
Filed: 1947-09-12
Abstract: 644,067. Pulse counting circuits. STANDARD TELEPHONES & CABLES, Ltd. Sept. 12, 1947, No. 25066. [Class 40 (vi)] In a counting circuit using gas-filled discharge tubes means are provided for compensating for variations in the supply voltage. Fig. 2 shows a pulse generator circuit used for supplying a triggering pulse from lead PL to each triggering electrode of a chain of cold-cathode gas discharge tubes which are connected to be sequentially fired by the combined effect of this pulse and a priming pulse applied from a preceding stage which has fired, Fig. 1 (not shown). The voltages +V1 and. - V are derived from the same source as the supply voltage for the counting circuit. When the amplitude of the priming pulse derived from a preceding stage changes due to a variation in supply voltage, the positive-going pulse at lead PL changes in amplitude in the opposite direction due to the limiting action of rectifier D and neon tube S, so that the sum of the two triggering voltages is maintained constant. The circuit may be overcompensated to give optimum performance. Specification 636,668 is referred to.

Title: Improvements in the production of cyclic condensation products
IPC: C07D213/81
Filed: 1949-09-30
Abstract: Condensation products are manufactured by condensing p-aminobenzoic acid, anthranilic acid, salicylic acid, p-hydroxybenzoic acid, p-nitrobenzoic acid or 2-aminopyridine-4-carboxylic acid with a polyhydroxyalkylated amine of the general formula NR2.(CnH2nO)xCnH2nOH (wherein n and x are whole numbers greater than 1 and R represents hydrogen or an alkyl or hydroxyalkyl group), or with diethylenetriamine, or with glycocoll or sarcosine or the addition products thereof with ethylene oxide.  The condensation may be carried out by heating the acid with the calculated amount of the amino compound, if convenient in the presence of a condensation catalyst or an auxiliary liquid, until substantially equimolecular proportions of the reactants have condensed and an equimolecular proportion of water split off.  In an example, p-amino-benzoic acid is heated with the reaction product of 1 mol. of triethanolamine and 6 mols. of ethylene oxide.  Samples have been furnished under Sect. 2 (5) of condensation products of: (I) salicylic acid with glycocoll; (II) p-aminobenzoic acid with the reaction product of 1 mol. of dodecylamine and 10 mols. of ethylene oxide.  The Specification as open to inspection under Sect. 91 comprises also the condensation of other cyclic carboxylic acids substituted by one or more hydroxy, amino or nitro groups or halogen atoms and other hydroxyamines, polyamines or aminocarboxylic acids. Additional examples describe the condensation of p-aminobenzoic acid with triethanolamine or its monolauric ester, dodecyldiethanolamine or the reaction product of 1 mol. of diethylaminoethanol and 10 mols. of ethylene oxide; in the first three cases, the p-aminobenzoic acid may be replaced by p-nitrobenzoyl chloride with subsequent reduction of the nitro group. Other starting materials specified are: o-chlorobenzoic acid, nitronaphthalenecarboxylic acid and aminoquinolinecarboxylic acid; mono- and diethanolamine, propanolamine, b -hydroxyethoxyethylamine and p-phenylenediamine.  This subject-matter does not appear in the Specification as accepted.
