Title: Method of and apparatus for controlling the pouring of molten  metal in a continuous casting process
IPC: B22D11/16
Filed: 1974-03-06
Abstract: 1463624 Continuous casting SUMITOMO METAL INDUSTRIES Ltd and SUMITOMO SHIPBUILDING & MACHINERY CO Ltd 6 March 1974 [6 March 1973] 10090/74 Heading B3F [Also in Division G3] The level of molten metal in a continuous casting mould is monitored, e.g. by using a gamma ray source 11, and a slide valve 2 is operated to adjust progressively the size of the orifice of a discharge nozzle of a tundish 1, which feeds the mould, to reduce any difference between the level and a predetermined reference level. A display indicator 13 indicates or records a signal from a scintillator 12 and this is compared with a reference level signal from a setting means 9. Any difference between the signal is fed to an amplifier 7 and compared with a signal fed back from a potentiometer 5 whose sliding contact is moved by a piston of a cylinder 4 which is moved in correspondence with that of a cylinder 3 which operates the slide valve 2. Output form the amplifier 7 operates a valve 10 for control of the cylinder 3. To avoid the need to change the tundish nozzle or slide valve owing to erosion, the basic maximum size of the orifice opening can be changed in stepwise fashion by use of a switch 6 to select different pairs of resistors, Fig. 3 (not shown), in the potentiometer 5 which correspond to these openings, so that a different range of opening sizes is selected by the normal operation of the sliding contact. To prevent complete closure of the tundish orifice, and therefore clogging, a voltage is applied to the potentiometer circuit or a limit switch is attached to its sliding contact.

Title: Improvements in or relating to means for applying sliding clasp fastener elements totapes
IPC: A44B19/46
Filed: 1948-04-12
Abstract: 642,804. Sliding-clasp fasteners. MARLOW, E. H. April 12, 1948, No. 10145 [Class 44] In a machine for the manufacture of sliding-clasp fasteners the means for the application of the elements to the tape comprise tape gripping feed jaws close to the position at which the elements are to be applied, operating means for the jaws to move them, when closed, in the feeding direction, then to release them, to retract them and again close them to grip the tape, there then being a period of dwell during which an element is secured to the tape. The feed jaws 80, 81, Fig. 2, form parts of levers 111, 110 which are pivoted at 114, 113 on slidable blocks 116, 115. Eccentrics engaging slots in the blocks, and carried on rock-shafts 123, 122 are adapted to reciprocate the blocks to cause the jaws 80, 81 to grip or release the tape. The rock-shafts carry arms 126, 125 coupled together in the centre and operated from a cam-shaft by a common push-rod. The levers are also formed with slots 131, 130 in which are engaged eccentrically mounted pins 133, 132 carried on rock-shafts 135, 134 operated in the same way by a pushrod. By this means the jaws 80, 81 are displaced upwardly to advance the tape to the next position. During the closing of the legs of the element on the tape, the tape is gripped below the element by a pair of jaws 72, 73, Fig. 4, which are carried on sliding blocks and operated through eccentrics and push-rods as before. A pair of jaws 70, 71, adapted to close the legs of the element, are operated in the same way. The tape gripping jaws and element fixing jaws together form a box into which the element is pushed from the chamber of the, shuttle as described in Specification 642,803, and the element is thereby accurately located with respect to the tape before being fixed thereto. Specification 642,802, [Group XXII], also is referred to.

Title: Improved modified polyesters
IPC: C08G63/68
Filed: 1963-03-14
Abstract: Fibre-forming polyesters have their dye-affinity improved by incorporating into the macromolecular chain links containing zinc carboxylate groups, the zinc content of the polyester being from 0.5 to 5 atoms of zinc per 100 structural units of the polyester. The polyesters are made by reacting (a) a dicarboxylic acid, e.g. terephthalic acid, isophthalic acid or 4: 41 - dicarboxydiphenylmethane (or ester-forming derivatives thereof); (b) a diol, e.g. ethylene glycol or 1: 4-di(hidroxy)cyclohexane (or ester-forming derivatives thereof) and (c) a zinc salt of an organic compound containing one carboxylic group combined with the zinc and two other groups capable of combining with the ester-forming groups in the mixture, e.g. a compound of formula <FORM:0992355/C3/1> where R1 is a lower alkyl radical and R2 is a trivalent aromatic, aliphatic or cycloaliphatic radical.  In examples, polyesters were made by reacting dimethyl terephthalate, ethylene glycol and (1) the zinc salt of dimethyl trimesate, (2) the zinc salt of diethyl 10-carboxydecyl malonate, (3) the zinc salt of 10-carboxydecyl malonate.  Specification 856,917 is referred to.

Title: Improvements in or relating to spray generators
IPC: B60S3/04
Filed: 1960-03-22
Abstract: 950,461. Washing vehicles. HOMESTEAD VALVE MANUFACTURING CO. March 22, 1960 [March 18, 1960], No. 10203/60. Heading B7J. In apparatus for spraying a vehicle with a cleaning liquid, the liquid is drawn from a tank 2, Fig. 1, by two pumps 8, 24, and is passed through a coiled heating pipe 17 containing an electric heater 33 to a line 18 carrying a discharge nozzle 21, and the inlet to the pump 24 is controlled by a valve 22 so that the rate of flow of liquid through the heater may be regulated to adjust the temperature and pressure of the discharged spray. The pumps 8, 24 are driven by a common piston-rod 27 from an electric motor 32 via a crank 30 and link 28. As a safety device a thermostat switch 48 de-energizes the motor 32 should the temperature within the heating coil 17 exceed a predetermined value. In a modified apparatus, the closure of a valve provided between the hose 18 and the nozzle 21 de-energizes the electric motor 32 by causing the opening of a fluid-actuated switch responsive to the pressure of liquid in the heating coil 17. In a further construction, pumps 8, 24, Fig. 3, draw the cleaning liquid from separate tanks 2, 2<SP>1</SP>, the inlet to the pump 24 being controlled by a valve 57, the operating coil of which is in series with a switch 61 controlled by the liquid pressure within the heating coil 17. The spray gun 20 has a rotatable nozzle head 64 so that either of two nozzles 65, 66 of different sizes may be used. When the larger nozzle 65 is used, the switch 61 remains closed and the valve 57 remains open so that both pumps 8, 24 are effective, but when the smaller nozzle 66 is used the switch 61 is opened to close the valve 57 and render the pump 24 ineffective. The spray gun having the rotary nozzle head 64 may be replaced by a gun having two independent nozzles of different sizes associated with a valve for diverting the flow from one to the other. A further valve may be provided between the hose 18 and the nose which when closed causes a fluid-pressure actuated switch to open to de-energize the motor 32. In another embodiment, the two pumps draw liquid from a common tank which may be supplied with either a strong solution of a cleaning agent or a weak solution through solenoid valves. The latter are controlled by a fluid-pressure actuated switch in such a manner that when the larger nozzle of the spray gun is used the weak solution is discharged thereby, and the strong solution is discharged when the smaller nozzle is used. The current supply to the apparatus may be controlled by a coin-operated timing device. Reference has been directed by the Comptroller to Specification 912,402.

Abstract: 1,205,587. Inking apparatus. BAKER PERKINS Ltd. 26 Feb., 1968 [4 March, 1967], No. 10356/67. Heading B6C. In an inking mechanism for a rotary web printing machine, having axially reciprocable inking rollers, means are provided for varying the amplitude of the reciprocation. Inward movement of the assembly of end-cap 14, bearing 13 and rotatable collar 12, by turning of cap 14 in screw-threaded mount 16, turns sleeve 21 on its supporting cross-pin 17, by way of linkage 36, so that as shaft 6 rotates sleeve 21 is wobble-rotated with it, with its axis angularly displaced relative to that of shaft 6 by an amount which increases as cap 14 is moved in. Non-rotating swash plate 23 is thereby given a corresponding oscillating movement which is transmitted to inking roller shaft 31 as an axial reciprocation. Adjustment of the magnitude of the reciprocation of roller 31 may be carried out while roller 31 is rotating and being reciprocated. Swash plate 23 may have four arms 26 each linked through a universal joint 27 to a bearing 43 on an inking roller shaft, and axially fixed inking rollers may be placed between the oscillating ones to make up roller trains.

Filed: 1945-04-25
Abstract: High molecular weight dimethyl silicones (mostly boiling above 200 DEG  C.) are prepared by adding dimethyldihalogensilane to a solid hydrated inorganic salt or metal hydrate other than an alkali or alkaline earth metal hydroxide.  Suitable materials mentioned are cupric hydroxide, ferric chloride hexahydrate, ferric sulphate heptahydrate, cupric sulphate pentahydrate, cupric chloride dihydrate, lead hydroxide, sodium carbonate trihydrate, sodium carbonate heptahydrate, sodium sulphate decahydrate, aluminium hydrate, stannic chloride pentahydrate, manganese chloride tetrahydrate, calcium nitrate hexahydrate, cobalt nitrate tetrahydrate, and hydrated silica.  On standing in contact with the hydrolysis medium, especially ferric chloride, sodium sulphate or copper sulphate the oily silicone may be converted into an elastic gum.  The silicone product may be washed with water to remove the hydrolysis medium or all or part of the hydrolysis medium may be allowed to remain in the dimethyl silicone as a filler.  In the example silica gel with the aproximate composition SiO212H2O was used to hydrolyse dimethyldichlorosilane.  The resulting buttery mass was mixed in a dough mixer with a little benzoyl peroxide and thickened during mixing to form a silicone elastomer.  Specification 594,481 is referred to.
