Title: Method of replacement of worn ropes in installations used for rope haulage
IPC: B66B19/02
Filed: 1967-02-08
Abstract: 1,128,126. Winching apparatus. OSTRAVSKO - KARVINSKE DOLY, OBOROVE REDITELSTVI. 8 Feb., 1967 [17 Feb., 1966] No. 6074/67. Heading B8B. A method for replacing old ropes 6 with new ropes 3 in mine winding gear comprises using the old ropes for the installation of the new ores. The new ropes 3 are fed from a winch 2 on to the mine winding sheave 4 which has been fitted with an auxiliary lining grooved to cater for the double quantity of ropes passing thereover. The free ends of the new ropes are clamped at 7 to the old ropes and as the upper haulage vessel 5 descends, the two sets of ropes are further clamped at intervals. When said vessel reaches its lowermost point, the new ropes are connected to the upper and lower vessels 5 and the old ropes are disconnected, whereupon on the next wind the old ropes may be unclamped and fed on to the winch 2. The auxiliary lining is then removed from the winding sheave 4.

Title: Improvements in or relating to stringed instrument musical machines
IPC: G10F1/18
Filed: 1925-03-05
Abstract: 242,850. Wade, H., (Mills Novelty Co.). March 5, 1925. Keyboard stringed instruments, bowed. To keep the speed of the electric motor operating a mechanical violin constant for any expression, irrespective of the load to which the motor is subected, there are provided means operated by a centrifugal governor for switching into or out of circuit certain of the motor resistances that normally are switched in or out by the expression controllers. As shown in Fig. 1 the governor comprises a ring 36a which rotates with the motor shaft 32 and carries a spring retracted lever 33 which is pivoted at 34 to a slotted sleeve 30. A plunger 29 working in the slotted sleeve rocks a bell-crank 23 about its pivot 24 to move a contact finger 20 into engagement with one of the contacts 21, 22 or to maintin a neutral position between them according to the movement of the ring 36a which is governed by the speed of the motor shaft. The normal circuit is through the positive wire 1 to the terminal N and the resistances A, B, C through the motor and the resistance D to the negative line 2. The expression is controlled by contacts on the tracker-bar 14 connected to terminals L, LL, LLL corresponding to increasing degrees of loudness and terminals S, SS corresponding to degrees of softness. When contact is made between the strip 20 and contact 21 a short circuit to terminal LL is made and the motor is consequently speeded up to neutralize the slower rotation caused bv the increased load, whereas if contact is made between the strip 20 and contact 22, a short circuit to the terminal S in the field windings is made and the speed of the motor is retarded. Specifications 10846/12 and 29654/13, [both in Class 88 (i), Musical instruments, Automatic], are referred to.
Patent GB-212910-A (GB)
Title: Improvements in and relating to asynchronous motors
IPC: H02K17/30
Filed: 1924-03-10
Abstract: 212,910. Henry, E. March 12, 1923, [Convention date]. Armatures and field magnets; alternating. current motors; motors, controlling.-The starting current and torque of a squirrel cage induction motor are controlled by magnetic plates or sleeves which are movable with respect to the rotor core for deflecting a portion of the stator flux, the rotor bars being joined by resistant conductors in which a self-induction is created. on starting by means of the movable magnetic plates. The magnetic discs 9, Fig. 1, may be moved by a fork or the like along the rotor shaft so as to engage the end plates 5 of the rotor when the motor is started. The rotor bars 6 are extended over the plates 5 and connected by resistant conductors 8 to the rings 7, the magnetic shunts 9 being grooved to receive the rings and conductors 8. The rotor may be made of thin laminae entirely, or partly of thick plates, or it may be solid, and the shunts 9 may be partly laminated. Fig. 6 shows a ring form of rotor 4 containing short-circuiting resistances 8 and having a magnetic shunt 9a in the form of segmental arms which enter the ring between its spider arms. The winding is also connected by resistances R, as shown in Fig. 8. The effect of the conductors 8, Fig. 1, and connecting resistances between the rotor bars is shown in Fig. 5. The stator flux normally enters the rotor surface at B, A, C, D and leaves at C, D, F, E, the effect of the magnetic shunts causes it to enter at C, H, L, E, D; D, J. K, F, and leave at A, G, H, C; B, I, J, D. The non- inductive resistances r carry a power current. The rotor bars 6, Fig. 1, may be connected in groups to the rings 7 by radial conductors 8, Fig. 11, having enlarged heads 8<1> and cast integrally with the rings 7, or as in Fig. 12, each conductor 6 may have several radial bars 8. The bars 8 may be replaced by a. flat iron-plate 8, Fig. 14, soldered to the ring 7 and having saw cuts 15; or an uninterrupted disc may be used with thin radial copper insets to increase the radial conductivity without increasing it circumferentially. The contacting surfaces of the magnetic shunts and the rotor may be coned, corrugated, or otherwise shaped so as to increase the contact area. When the inner surfaces of the magnetic shunts are not grooved to receive the end parts of the rotor bars the shunts may run loosely on the shaft or they may be supported on the shaft bearing during normal running. They may, alternatively, have only an axial movement on a fixed part of the motor without rotation, in which case thev are formed of a helically laid band of thin metal. In another form, they have movable projections which are moved out for the starting period. The shunts may be moved by hand, electromagnetically, by a servo-motor or a centrifugal device may be used in which after a preliminary setting against the action of a spring they are withdrawn from the rotor at a limiting speed. They may also be drawn in by the flux of the motor itself at starting.

Title: Improvements in or relating to steam turbines
IPC: F01D25/26
Filed: 1937-03-01
Abstract: 486,340. Elastic - fluid turbines. RODER, K. March 1, 1937, Nos. 6118, 6119, and 6120. Convention dates, Feb. 29, 1936, Oct. 9, 1936, and Nov. 4, 1936. [Class 110 (iii)] A steam turbine has a guide blade carrier a, which though subdivided in at least one axial plane, is formed as a true body of revolution, i.e. any section in a plane at right-angles to the axis of rotation of the rotor b is a true circle, and is held in position by one or more supporting members d, d<1>, lying in the steam space and themselves constituting true bodies of revolution, the carrier and the supporting member or members being so assembled that the subdivided carrier as a whole acts as an undivided true body of revolution. One of the supporting members d<2> may be constituted by a single unit, i.e. a ring or it may be subdivided in an axial plane at right-angles to the plane of subdivision of the carrier. One of the supporting members c<1> may also be carried by an internal annular wall c<11> integral and concentric with the housing. The shape, size and position in the flow of steam of the supporting members are so chosen that they will respond to temperature variations more rapidly than the adjacent parts of the rotor so that during starting up when the temperature changes are large the clearances will first increase and then decrease. The materials from which the carrier parts and the rotor are made preferably have approximately the same coefficient of expansion. The casing is so arranged that those parts, i.e. steam connections, which cause the housing to deviate from a true body of revolution are so arranged that any deformation of the housing on one side is balanced out by an equal deformation on the other side.

Title: Improvements in and relating to the manufacture of garments from regenerated cellulose
IPC: D06M15/70
Filed: 1960-02-23
Abstract: "Wash and wear" garments are made by cutting a shrinkable woven fabric containing more than 20% by weight of regenerated cellulose fibres to form a garment segment which is longer in the warp and filling directions than is desired in the finished garment by an amount approximately equal to the relaxation shrinkage of the garment, i.e. the shrinkage which occurs when the tensions introduced into the fabric and its individual yarns during textile processing are released, joining the garment segments to form the garment, subjecting the garment to relaxation shrinkage by an aqueous treatment, impregnating the garment with a cross-linking agent for the regenerated cellulose fibre and pressing and curing the impregnated garment.  The garment segments are preferably cut 10%-25% larger in the warp direction and 0%-5% larger in the direction of the filling than is desired in the finished garment, and the garment segments may be joined by sewing or by use of an adhesive, e.g. the fabric may contain thermoplastic fibres such as cellulose acetate which are rendered adhesive by heat to cause joining, or an adhesive may be applied to the areas to be joined and the areas pressed together and dried.  The garments may be shrunk by agitation in water at 140 DEG F.-180 DEG F. for 1/2 -4 hours.  If the fabric has been sized before cutting, e.g. with 4%-12% by weight of starch, gums or polyvinyl alcohol, the garments may be desized and shrunk simultaneously with an aqueous solution of a desizing agent, e.g. an aqueous solution containing 1%-3% by weight of a diastatic enzyme at 140 DEG F-180 DEG F. for 30 minutes to 4 hours.  The cross-linking agent may be formaldehyde or an amino plast, e.g. urea-formaldehyde, melamine - formaldehyde, dicyandiamide - formaldehyde and guanidine formaldehyde condensation products, but it is preferred to use dimethylol cyclic ethylene urea compositions containing polymethyl methacrylate, silicone lubricants, softening agents and a catalyst such as ZnCl2, Zn(NO3)2 or MgCl2. 6H2O.  Other specified cross-linking agents are acetone-formaldehyde, acrolein-formaldehyde and polyepoxy resins, e.g. polyfunctional compounds having at least two epoxy groups linked through a hydrocarbon, polyhydric phenol or polyhydric alcohol group. Creases or pleats may be inserted in the garment impregnated with the cross-linking agent before curing.  The garments may be pressed in a "hot head" press at a temperature of 300 DEG F.-330 DEG F. at air pressures of 20-80 p.s.i. or dried at 140 DEG F.-200 DEG F. and then pressed and cured, with or without the presence of moisture, at 1/2 -20 p.s.i. and 250 DEG F.-300 DEG F. After pressing the garments may be hung in an oven at 300 DEG F.-350 DEG F. for 3-10 minutes or at 230 DEG F.-300 DEG F. for 15 minutes to several hours. Specified garments are aprons, vests, dresses, coats and shirts. Specification 796,815, and U.S.A. Specifications 2,504,835, 2,696,477, 2,711,971 and 2,752,269 are referred to.

Abstract: 267,917. Dubilier Condenser Co. (1925), Ltd., (Assignees of Pfiffner, E.). March 22, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Condensers.-Homogeneous films of cellulose derivatives such as cellulose esters and ethers for the dielectrics of electric condensers are made by superposing separate films before complete hardening, so that they may be united but without the passage of any impurity from one constituent film to another. The apparatus is similar to that used for making single films, but the spraying device is multiple, and the individual film bands meet on the common support in such a state of plasticity that they combine together free of bubbles and show no stratification on drying. The uniting of the films may be facilitated by the use of pressure and heat. The metal foil constituting the conductor may serve as base for the composite film. One of the claims is for making the film by pouring the film elements upon a smooth hard support whereby the excess of solvent in the freshly poured film dissolves the upper surface of the dried film, and the union of the layers is effected.
