IPC: B21C47/30
Filed: 1952-12-18
Abstract: 742,994. Collapsible spindles. DAVY & UNITED ENGINEERING CO., Ltd. Dec. 7, 1953 [Dec. 18, 1952], No. 32124/52. Class 100(1). [Also in Group XXII] A coiler drum for strip, e.g. from a rolling mill, having a number of segments outwardly movable relatively to one another to positions in which the drum is in an expanded condition from which it may be contracted to enable a wound coil to be removed includes a jaw on one segment, a second jaw arranged to co-operate with the first to grip the end of the strip to be wound on the drum and means for moving said segment outwardly to expand the drum while causing the jaws to close to grip the strip, one of the jaws being yieldable during closing. A rotatable central member 1 carries three drum segments 2, 3, 4 interdigitated at their adjacent edges 67 and keyed at their ends to move radially in flanges on the member 1. The segments are moved outwardly against springs. 39, 59 acting between their ends and collars on the central member 1, by longitudinal movement of wedge members 13, 14, 15, slidable in recesses on the member 1, which engage wedge surfaces 21 and 22, 23, 24 respectively, on the segments and are reciprocated by an actuator rod 30 movable in a central bore in the member 1. One gripper jaw 8 is fixed on the segment 2 on one side of a strip end receiving slot 79 therein and a co-operating jaw 9 is movably mounted in the segment 2 on the opposite side of the slot 79. The jaw 9 is moved outwardly as the segments are expanded, but faster than such expansion, by a wedge member 75, whose wedge surfaces are steeper than those of the segment wedge members, which is secured in a recess in the member 13 and engages a wedge surfaced thrust member 72. The member 72 pressing, through a series of springs 73, a plunger 76 carrying the jaw 9 so that when the jaws are closed on the strip end, the springs take up the movement of the member 72. As the drum contracts the member 72 moves inwardly until flanges 87, 88 thereon engage shoulders 89, 90 on the plunger 76 and the member 72 and plunger 76 is then moved as a unit by springs 77, 78 to open the jaws. The various wedge surfaces are lubricated by a duct system. Specifications 712,246 and 712,247 are referred to.

Title: Improvements in and relating to electric closed-loop control systems
Inventor: ALSOP CHARLES FRANCIS
IPC: B21B37/60
Filed: 1959-09-22
Abstract: 958, 961. Electric correspondence control systems. ENGLISH ELECTRIC CO. Ltd. Sept. 16, 1960 [Sept.22, 1959], No. 32183/59. Heading G1N. The separation of the rolls of a rolling mill is determined through coarse and fine synchro links, incorporating means for (a) presetting the change in separation required for the next rolling pass, (b) neutralising the change signal without altering the input separation signal, and (c) adjusting the zero relationship between the input and output members. As shown, the required separation of the rolls 10,11 is manually inserted into coupled synchros 25, 29 by a selector 33, the coarse signal being fed through synchros 28, 27, 26, 20 and the fine signal through synchros 24, 23, 22, 19, to an amplifier 16 feeding screw motors 14, 15 eliminating the error signals in receiving synchros 19, 20. The change in separation for the next rolling pass is preselected by lever 42 attached to the rotor of synchro 43, followed by electrically coupled synchro 41 which also rotates a shaft 39 controlling the gear ratio in unit 36, which couples a motor 38 to shaft 35 and the rotors of synchros 24, 28. Motor 38 is arranged to rotate through a predetermined angle when energized by press-button switch 42a, to produce an additional angular rotation of synchros 24, 28 which is a function of the setting of lever 42. The separation between the rolls 10,11 follows the additional signal fed into synchros 24, 28, at the conclusion of the first pass. Coupled with synchros 24, 28 is a further synchro 45 which, via synchro 46 and motor 49, will rotate synchros 23, 27 to nullify the additional signal from lever 42, and restore the roll separation signal to that indicated on selector 33. This is effected by closing switch 47. The zero position of the system is adjusted manually by device 52 coupled to the rotors of synchros 22, 26.

Title: Electrolytic process for the manufacture of chemical compounds
IPC: H01M4/86
Filed: 1930-10-27
Abstract: 363,054. Electrolysis. CLARIANA, A. L., Valldemosa, Balearic Islands, Spain. Oct. 27, 1930, No. 32195. Convention date, Jan. 24. [Class 41.] In a process for the manufacture of chemical compounds other than those which are merely produced from the electrolytic decomposition of the electrolyte, the cathodes are made of or covered with a layer of a sponge or very fine particles of a metal which is easily oxidizable in air but whose oxides will have no harmful effects on the compounds produced ; the cathodes are alternately oxidized in the air and reduced during the electrolysis. Diaphragms may be employed or not. In the manufacture of lead hydroxide the electrodes are of lead, the cathode having a precipitated layer of spongy lead, and the electrolyte of sodium chlorate solution. A current density of 0À5 amps per sq. dcm. at 1À3 volts is employed. After 45 minutes treatment the electrolyte and the precipitated hydroxide are removed and the cathodes rested for a similar period. In modifications re-oxidation is effected by the use of two sets of cathodes one of which is raised while the other is submerged, or by the use of partially submerged cathodes which are slowly rotated.

Abstract: 1,112,346. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 13 July, 1966 [28 July, 1965], No. 32379/65. Addition to 1,086,060. Heading G6C. A nuclear reactor comprises a fuel rod cluster with perforated guide tubes interspersed among the fuel rods, control pins insertable with clearance into the guide tubes, an operating assembly for inserting and withdrawing the control pins, and conduit means adapted when required to supply liquid coolant to the operating assembly, which coolant subsequently passes to the guide tubes to be sprayed therefrom over the fuel rods. Referring to Fig. 2, each cluster 3 is associated with an operating assembly 6 comprising a control mechanism housing 7 extending between a control mechanism support grid 8 and the upper core support grid 4, the housing 7 being openended and in communication with the cluster 3. Each cluster 3 comprises a number of spaced fuel rods (not shown) on a triangular lattice with spaces for guide tubes 9 in which control pins 10 are insertable with clearance. The guide tubes 9 have perforations 14 distributed over their length, those of one tube being staggered relative to those of an adjacent tube. Each housing 7 contains a piston 15 releasably connected at its lower end to a carrier 16 from which the control pins 10 are carried. The upper end of the piston 15 is connected by a releasable connection 17 to a driven member 18 and is housed in an apertured dashpot 19 mounted from the housing 7. A scram spring 20 extends between the carrier 16 and the grid 8, and in the region of the grid 8 the housing 7 communicates with a housing 21 of a control mechanism drive system 22 forming part of the operating assembly 6. The driven member 18 of the system 22 is actuated by a motor (not shown) mounted on the reactor pressure vessel. The housing 21 is in valved communication with an emergency coolant supply in a storage tank and when required, coolant from this tank is caused to flow through the housing 21 into the upper ends of the tubes 9 to spray out through the perforations 14 on to adjacent fuel rods (as indicated by arrows 28). The perforations 14 may be absent from the lower ends of the tubes 9, or they may be metering orifices of a different size so that by a dashpot action the pins 10 are subject to endof-stroke cushioning when a rapid shut-down insertion is made. The emergency coolant supply may be under gravity from an elevated storage tank or by means of a pump system. In the case of a pressurized water reactor, there may be a pump of high pressure and low volume delivery suitable for meeting the occurrence of a low rate of depressurization and escape of the pressurized water coolant and also a pump of low pressure and high volume delivery where the same occurrence is at a fast rate.

Title: Improvements relating to fluorescent pigments
IPC: C08F2/44
Filed: 1952-12-23
Abstract: A pigment for forming inks, enamels and coating compositions comprises a solid solution of a water-soluble fluorescent organic dyestuff in a thermoplastic resinous substrate consisting of a polymeric product of at least one vinyl type monomer, the ratio of dyestuff to substrate being from about 0.2 to about 5 per cent based on the weight of the resin, the pigment imparting a brilliant fluorescence in daylight or in ultra-violet light to a film comprising the pigment and a suitable binder or vehicle. The resinous substrate usually consists of polyacrylonitrile or a copolymer, the major portion of which is acrylonitrile.  In one example to an aqueous dispersion of polyacrylonitrile containing polymer solids in the wet gel state or water slurried state glacial acetic acid was added with stirring to form an emulsion and then a water solution of Rhodamine 6G, Rhodamine B and Uramine B-4315.  The mixture was stirred, filtered and washed, and the resulting pigment air-dried and ground and made into an enamel film with a long oil alkyd resin and a urea formaldehyde resin.  Hydrochloric acid can be used instead of acetic acid or the acid omitted.  In other examples the resinous substrate can be a copolymer of acrylonitrile containing 10 per cent glycidyl methacrylate, 10 per cent 2-hydroxyethylmethacrylate, 10 per cent dichlorostyrene, 10 per cent maleic anhydride, 5 or 10 per cent acrylamide or 5 per cent acrylic acid, or can be polyethylene, polychlorotrifluoroethylene, polydimethylstyrene or a copolymer of acrylonitrile, vinyl acetate and vinyl pyridine.  In the latter case the copolymer was pretreated in a rising temperature bath prepared by mixing with water solutions of sodium chlorite, " Calgon " (Registered Trade Mark) and sulphated dodecyl alcohol (sodium salt) and adding concentrated nitric acid.  The polyethylene, polychlorotrifluoroethylene and the polydimethylstyrene can be slurried in a mixture of water and alcohol.  The water dispersion of polyacrylonitrile can have added to it the sodium salt of sulphated dodecyl alcohol or polyacrylonitrile powder can be dissolved in dimethyl formamide. In another example, the dye was dissolved in acrylonitrile and the product emulsion polymerized.  A water dispersion of a polyamide resin can be added to the polyacrylonitrile-dye complex.  Dyes or mixtures of dyes referred to in the Specification include Rhodamine 6G, Rhodamine B, Uramine B-4315, Auramine, Calcomine Brilliant Flavine S, Brilliant Sulfoflavine FS, Calcozine Flavine TG, 4 - methyl - 7 - diethylamino coumarin, Calcocid Blue EG, Calcocid Alizarine Blue SAPG, Calcocid Green G, 4-beta-hydroxyethylamino-1,8-naphthalic N-butylimide (Calcofluor Yellow HEB), Calcocid Malling Green 6B, Calcocid Milling Fast Green CR and Phthalocyamine Green.

A throttle valve (not shown) in the inlet to a compressor is automatically adjusted to maintain the output pressure within predetermined limits. The throttle valve is adjustable by rotating a shaft 33<SP>1</SP> movable by a device 10 comprising pistons 31, 32 loaded by springs of differing rate. The pistons are subjected to the pressure in the compression cylinder 7 through a tube 29, 29a, 29b filled with liquid or connected directly to the cylinder 7. Assuming the final compression pressure lies between the predetermined limits, then only the low-pressure piston 31 is moved. This causes pivoting of a lever 34 and consequential anti-clockwise rotation of a ratchet 33 connected to the shaft 33<SP>1</SP>, However, this adjustment is immediately nullified by equal rotation of the ratchet in the reverse direction by a lever 35 actuated by a crankshaft driven cam 37. If the pressure is excessive, piston 32 is also operated to cause twice the amount of anti-clockwise movement, whereas if the pressure is too low neither piston is actuated. Hence the subsequent operation of the lever 35 causes a change in the adjustment of the throttle. Gas compressed in the cylinder 7 may pass to a valve which directs the output either through a by-pass line or through the inlet valve of a second stage cylinder.
