Title: Disperse dyestuffs containing halotriazinyloxy groups and processes for their production
Inventor: MERIAN ERNEST
IPC: C09B62/04
Filed: 1960-10-20
Abstract: 970,936. Reactive disperse dyes. SANDOZ Ltd. Oct. 20, 1960 [Oct. 23, 1959], No. 36031/60. Heading C4P. The invention comprises disperse dyes free from water-solubilizing groups which dyes contain at least one triazine ring attached to the dyestuff radical through an oxygen atom and which triazine ring contains at least one chlorine or bromine atom. The dyes are prepared by condensing disperse dyes containing at least one hydroxy group with a di- or tri-halotriazine. Diazo or coupling components containing hydroxy groups may be similarly reacted and subsequently converted by the coupling reaction into azo dyes. Dyes containing two halogen atoms on the triazine ring may be further reacted e.g. with an amine to replace one of the halogen atoms. The dyes may be used to dye, pad or print hydrophobic fibres e.g. polyamide, polyester, polyacrylonitrile, polyurethane, polyvinyl chloride and cellulose acetate fibres, preferably with heating and in the presence of acid-binding agents. In examples the preparation of mono- and dis-azo, anthraquinone and nitro dyes is specified.

Title: Improvements in or relating to electric signalling systems
IPC: G09F13/00
Filed: 1931-02-05
Abstract: 371,964. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd. and GRIFFITHS, J. B., Columbia House, Aldwych, London. Feb. 5, 1931, No. 3654. [Class 40 (i).] In a train indicator system in which designations are stored on registers and shown in a predetermined order, when the first indication is cancelled the indications stored on the registers are transferred in turn to the preceding registers under control of a common rotary switch. All indications are extinguished during the transfer process. An indication on a particular register can be cancelled and replaced without affecting the setting of the remaining registers. The system described employs direct manual control of the setting, but this can be replaced by a code signalling system of the type described in Specification 366,919. If the designation on the first indicator is to be 2, key 2 is depressed and A2 pulls up and locks, completing circuits for lamp LA2. Relay S1 operates and locks, transferring the control circuits to the second register. If the next indication is to be 3, key 3 is operated and B3 pulls up, lighting LB3 and energizing S2. Similarly the 3rd, 4th, and 5th indications are stored on relay groups C, D, and E respectively and control lamp groups LC, LD, LE. When a train leaves the station track contacts RC1 operate and K pulls up. Clutch C operates and locks the cams to a rotating shaft. As the cams move C locks over CH and the circuits for all lamps are broken over BS. K, which locked to RL, releases. At the first step off normal the circuit of the operated A relay is broken over AL and the relay releases, S1 being held over AB. At the second step AT completes a circuit for the operated B relay to energize the relative A relay, which locks, and at the third step the operated B relay falls away. Similarly the remaining registers transfer their indications in turn to the next preceding register. When one revolution of the switch has been made C releases and BS completes the circuits for the indicator lamps. Another designation can then be set up on the final register. Should it be required to cancel and replace an indication the relative key CK, e.g. CKC, is operated. The energized C relay releases and S3 falls away. A next indication set up is thus registered on the C relay group, the other register groups being unaffected.

Title: Improvements in or relating to machines for beaming or winding yarn
IPC: D02H3/00
Filed: 1949-02-11
Abstract: 661,463. Beaming warps. HIBBERT & CO., Ltd., J., and HIBBERT, H. April 25, 1950 [Feb. 11, 1949], No. 3765/49. Class 142 (iv). A pressure roller is held against the warp during beaming by a hydraulic ram coupled to a pump which starts and stops simultaneously with the drive to the beam. A pump 15, coupled by a pipe 16 to an oil tank 17, delivers oil under pressure to a cylinder 4 through a pipe 18. A ram 5 is thereby moved further out of the cylinder and a pin 7 engaging a slot in an arm 8 rotates a shaft 9 and raises the presser roller 11, carried by an arm 10, into contact with the beam. As the diameter of the warp on the beam increases, the arm 10 is moved downwards and the increased pressure in the cylinder 5 causes the oil to open a valve 20 and flow back to the tank 17 through a pipe 19. When the drive to the beam is stopped the pump is also stopped and the arms 10 fall due to gravity. The oil then feeds back through the pump to the tank. Two pumps and rams may be provided and remote control through electric switches may also be fitted.

Abstract: 328,924. Ryles. E., and Sopwith, J. Feb. 5, 1929. Interconnected valve members controlling a single passage - way. - Liquids are aerated by spraying under pressure through a nozzle, adapted to deliver a main jet of atomized liquid, controlled by a valve the stem of which constitutes an inner nozzle adapted to deliver a fine jet, aeration being effected by induction of air or gas through holes bored around the orifice of the main nozzle. The compound nozzle is supplied from a chamber c, the main jet being formed by helical grooves h on the stem of a valve member f by which the discharge is regulated, the grooves impinging tangentially into the orifice of the main nozzle. A fine jet is formed by helical or other passages m leading at a suitable angle to a central bore g in the valve stem. Holes e bored in the main nozzle may supply air or a gaseous mixture. The chamber c may be supplied by means of a pipe attached to the threaded orifices l<1>, but, as shown, the main supply comes from a chamber a which may be connected to a water tap, water main, or other supply under pressure. Communication between the chambers is controlled by a manuallv actuated disc or cone. valve member b having a lost motion connection with the valve member f so that except when the valve b is fully open only the fine jet is operative. A secondary connection by means of the threaded orifice P enables the chamber c to be used as an intermediate aerating or mixing chamber, any desired gas, liquid, semi-liquid or finely powdered material being fed thereto to be mixed with the liquid passing through from the chamber a. The valve f may be fixed in a more or less open position to provide a compound jet of suitable character, the valve b being similarly set and the supply controlled by an independent tap.

Title: A method for cold-working metals
IPC: B21D22/20
Filed: 1960-02-03
Abstract: A method for cold working metals is characterized by the combination involving applying to the metal surface a solution of polyvinyl acetate in trichlorethylene, the polyvinyl acetate having an average molecular weight of 30,000 to 70,000, evaporating the trichlorethylene, heating the polyvinyl acetate layer to a temperature above its softening point e.g. 150 DEG -200 DEG C. for 5-10 minutes, applying a lubricant on the polyvinyl acetate layer, subjecting the metal to the desired cold working process, and treating the cold worked object with trichlorethylene to remove the polyvinyl acetate and the lubricant from the metal surface.  The solution of polyvinyl acetate is applied by dipping, spraying or rolling.  Mineral, animal or vegetable fats and oils or soaps of higher fatty acids, e.g. calcium stearate and aluminium, naphtenate mixed with an oil are used as a lubricant. After the cold working the objects are placed in vapour generated by boiling trichorethylene the vapour condensing on the cold object to dissolve and so remove the plastic coating and lubricant.  In an example polished saucepans are manufactured from blanks punched from a sheet of stainless metal the blanks having been dipped in a 10% solution of polyvinyl acetate (molecular weight 60,000) in trichlorethylene.  The plastic coating is heat treated at 160 DEG C., coated with a viscid chlorinated paraffin and deep drawn.  Finally the coating and lubricant are removed.

Title: Improvements in or relating to Switched Voltage Regulators
IPC: H02M3/156
Filed: 1967-01-25
Abstract: 1,172,543. Automatic voltage control. MARCONI CO. Ltd. Jan.25, 1967 [Jan. 27, 1966], No.3841/67. Heading G3R. In a voltage regulator of the type including a switching transistor which is connected to load terminals by way of a filter constituted by a series inductor and a shunt capacitor, means are provided to limit the transient current flow, due to the charging of the said capacitor, which occurs when the regulator is initially switched on. As shown, a load 8 is supplied from a source 1 by way of a switching transistor 3 and an inductance/ capacitance filter 5, 6, the transistor 3 being controlled in known manner by circuitry 9, 10, 11 so that the voltage across the load is maintained constant; associated with the transistor 3 are a further transistor 19, resistors 4, 14, 15, 16 and 17, and a capacitor 18 inter-connected as illustrated. In operation, when the regulator is first switchedon capacitor 6 acts momentarily as a short-circuit, but as transistor 19 is initially in a high-resistance state the transistor 3 is rendered practically non- conducting, so that current does not flow to the capacitor; however the potential divider 14, 15 allows a voltage to be applied from the integrating circuit 17, 18 to the base of transistor 19 sufficient to bring the latter gradually into conduction, allowing base current to flow to transistor 3 and in turn allowing current to flow into capacitor 6 at a controlled rate. This effect is cumulative and continues until capacitor 6 is fully charged; the transistor 19 then is fully conductive and transistor 3 operates in normal manner. Thus, the power required to be dissipated in the transistor 3 during the initial transient period is materially reduced. Additionally provided in the circuit shown is a further integrating circuit 12, 13 the effect of which is to make the reference voltage, present in the control circuitry 9, 10, 11, rise at a controlled rate from zero at initial switch-on to the final predetermined value, so that switching of transistor 3 will also occur during the initial transient period, thereby reducing still further the power required to be dissipated in the transistor.
