Title: Improvements in cloth piling machines
IPC: B65H45/103
Filed: 1922-11-17
Abstract: 205,368. Norton, D. G., and Norton & Co., Ltd., Sir J. F. Nov. 17, 1922. Piling materials in rope form.-The carriage a carrying the piling-mechanism is traversed backwards and forwards over the pit or pits into which the cloth is to be piled, by an electric motor f mounted thereon, all external gearing being avoided, and the length of the traverse is determined by adjustable stops i carried by the track c and which actuate a switch for reversing the motor; the motor f drives one axle d of the carriage through reduction gearing e. The driving mechanism for traversing the guide eye p is also carried on the carriage, and as shown, comprises a separate electric motor j which drives through suitable reduction gearing k, m, n, a cross-shaft o having right and left hand threads for reciprocating the guide eye; after passing through the latter the cloth is taken to a winch w carried by one of the intermediate shafts. The electric motors and the driving gearing are mounted at one side of the carriage away from the winch and guide eye so that water of condensation and oil cannot fall from the former on to the cloth in the pit. According to one Provisional Specification, the carriage is traversed by an electric motor running continuously in one direction, the necessary reversal of the drive being derived from electromagnetic clutches mounted on the driving axle of the carriage and the current to which is controlled by the stops on the track; and with this construction the same electric motor is employed to drive the mechanism for reciprocating the guide eye.

Title: Improvements relating to encapsulated materials
Inventor: WELLER BRION
IPC: B01J13/16
Filed: 1963-08-09
Abstract: Droplets or particles of a first reactive substance which is a hardening reagent for resins, a curing agent for natural or synthetic elastomers, or which is capable of reacting with one or more substances to produce an adhesive or surface coating composition are enclosed in a solid covering by dispersing the droplets or particles in a phase (liquid or gas) containing a substance which reacts with the particulate material at the particle faces to form a solid compound which coats the particle. A specific example relates to the encapsulation of a solution in bis-(tetrahydrofurfuryl) phthalate of boron trifluoride diethyl etherate complex by dispersion in a low-boiling naphtha hydrocarbon solvent to which vinyl cyclohexane diepoxide is added. The capsules are used as an internal curing agent for a bifunctional epoxide resin ("Epikote" (Trade Mark) 828) into which they are mixed-the application of pressure thereto rupturing the capsules and causing hardening of the resin.  In a second example, Epikote 828 mixed with a little finely-divided silica is dispersed in the same hydrocarbon solvent to which the BF3 complex of the first example is added.  A paste is prepared by mixing the capsules so formed with a solution of the BF3 complex in bis-(tetrahydrofurfuryl) phthalate to produce a composition which is a self-curing adhesive on the application of pressure.  A third example relates to the encapsulation of diethylene triamine (plus silica) droplets in the same way using tolylene 2,4-diisocyanate as the reactant. The capsules produced may be used as an internal hardener for " Epikote " 828 as before.

Title: Improved manufacture of wrought iron
IPC: C21C3/00
Filed: 1921-11-25
Abstract: 174,904. Ford, E. L. June 31, 1921, [Convention date]. Purifying and refining.-In the manufacture of wrought iron by the puddling process, the metal bath is cooled below the melting point of the metal, before the end of the period of removing silicon and phosphorus, by adding oxide of iron either-cold or preheated. The iron is granulated and carbon monoxide is given off and burnt. When the flames of burning gas die down, the temperature of the bath is raised as rapidly as possible to a welding heat, when the particles agglomerate and are balled by hand or mechanically. To remove the silicon and phosphorus rapidly, the molten pig iron should be fed into the puddling furnace at a temperature high enough to combine rapidly with the ferric oxide and to oxidize the metalloids other than carbon.

Title: A variable ratio planetary type drive
IPC: F16H61/662
Filed: 1956-10-22
Abstract: 810,856. Driving dynamos; McCULLOCH MOTORS CORPORATION. Oct. 22, 1956 [Nov. 7, 1955], No. 32061/56. Class 35. [Also in Groups XXIV, XXVI, XXVII and XXXII] An I.C. engine dynamo 11, Fig. 1, is driven from the engine crankshaft 18, Fig. 10, via a variable-speed gear comprising a cage 38 having a rubber crank-shaft drive connection 42 and entraining balls 31 rolling between a resiliently mounted stationary split race 28a, 28b and a split race 27a, 27b entraining dynamo drive pulley 141. The race halves 27a, 27b are urged together by Belleville washers 33 and the race halves 28a, 28b by a Belleville washer 35 and by a piston 120 under hydraulic control, the washers 33, 35 being operative over a part of their range in which they have a negative spring rate (see Group XXXII). The gearing arrangement is such that dynamo speed increases faster than engine speed at low engine speeds and more slowly than engine speed at higher engine speeds, gear ratio variation being effected conjointly by centrifugal force acting on the balls, by the springs 33, 35 and by oil pressure acting on the piston 120 under the control of engine speed and temperature. On engine starting, an oil pump 125 driven from the pulley 14<SP>1</SP> supplies oil to the piston 120 via a valve 130 which closes under governor control as engine speed increases, a valve 131 controlled by a thermostat 135 in the engine cooling system opening on engine overheating to again supply oil to the piston 120. Modifications.-In Fig. 2 (not shown) the hydraulic control is dispensed with. In Fig. 7 (not shown) the gearing unit is built into a dynamo, the drive pulley of which carries a cage for balls rolling between an outer split race rotatively fast in the dynamo housing and an inner split race rotatively fast on the dynamo shaft. In Fig. 5, to effect hydraulic control the washers 33 are replaced by washers 62a, 62b acting in conjunction with a piston 56 under the control of valves 70, Fig. 6, thrown outwards centrifugally with engine speed increase to block a vent passage 68 and allow oil supplied via ducts 65, 66 to act on the piston 56.

Abstract: 444,417. Converting waste into material suitable for drafting and spinning. KERN, R., 172, Volksgartenstrasse, Gladbach, Munich, Germany. Nov. 9, 1934, Nos. 32243 and 32244. Convention dates, Nov. 9, 1933. [Class 120 (iii)] Knotted and entangled waste of artificial silk, wool, or ramie is converted into material suitable for ultimate drafting and spinning by teasing or combing out the waste into a fleece, drawing this fleece by rollers through a gilling or heckling machine to render the fibres or threads parallel and to straighten out looped threads, and cutting the so treated fleece into regular sections to give uniform staple fibre length. Cop waste, cop bottoms, tangled hanks &c. are roughly combed and then treated to eliminate loops in a gilling or heckling apparatus e, Fig. 3, having needle bars f, projecting loop ends being gripped by rollers r and the threads pulled round the needles f. The sliver or fleece is then cut to the desired staple length by knives operating on lines S<6> ... S<10> and the sliver k, Fig. 5, subsequently passed through a drawing frame having rollers z<1>, z<2>, z<3> which are heavily weighted to break any long fibres remaining therein. The final sliver l may be spun on a coarse flyer frame. In a modified arrangement of apparatus the rough combed thread mass is fed on a lattice to feed rollers y, Fig. 6, and thence to a gill box having strong needles f travelling faster than the rollers y and extending for a length greater than that of the longest fibres or threads. The material then passes through heavily weighted rollers r, r<1> running considerably faster than the speed of feed of the material. A rapidly rotating bladed roller o is provided to clear the top roller r<1>. The material is then passed over a table p to a pair of rollers q, ql which rotate slightly faster than the rollers r, r<1>, and then to a cutting or stapling device m.

A rotary boom-type sprinkler has a hollow rotary mast 17 from which booms 18 radially extend, and each carries a fixed main liquid nozzle 19 at its outer end, a fixed auxiliary nozzle 20 which, under the influence of the prevailing wind, provides intermittent liquid precipitation in a predetermined area during a portion of each revolution, driving nozzles 21 which rotate the mast at a substantially constant speed under variable wind conditions, and sub-boom sprinklers 22 attached to the booms. The mast rotates on a wheeled frame which includes a tube 24 by which liquid is fed to the mast and booms, and the latter are supported by frame members 45, Fig. 3, guy-wires 46 and cables. Each auxiliary nozzle 20, Fig. 10, has an outlet orifice 71 directed generally parallel to the boom and is liquid fed from the boom via a valve 72 operated by an arm 79 attached to a wind-vane 78. The arrangement is such that as the sprinkler rotates and the boom starts its upwind swing, Fig. 7, the valve 72 is closed, whereas during the. downwind swing the valve is opened by the wind acting on the wind-vane, and an otherwise uncovered area 67 is sprayed. Each boom may have a number of auxiliary nozzles arranged to operate at various wind velocities to compensate for a neglected spray area 67 which would normally expand with increasing wind velocity. Each driving nozzle comprises an L-shaped body 81, Fig. 12, with an outlet orifice 82 and a windvane 84, whereby the nozzle may be swung by the wind about the vertical axis of a conduit portion 86 and against the force of a spring 94. The nozzle swings between two stop positions, and the arrangement is such that when the boom rotates in prevailing wind the driving nozzles are swung on the boom so as to increase or decrease the driving torque to keep the boom speed substantially constant. Each boom may have a number of driving nozzles each with control springs of different strength so that the various nozzles move in response to wind velocities of varying intensity. Each subboom include a vertical conduit 110, a valve 113 and a distribution pipe 111 with outlets.
