Title: Method for the preparation of copper sulfide films and products obtained thereby
IPC: G03G5/10
Filed: 1962-07-23
Abstract: A transparent electrically conducting film is formed on a flexible polymeric tape substrate, by nucleating the surface of the substrate with a low surface-mobility metal, e.g. Cu, followed by vapour depositing a crystalline layer of a zinc or cadmium sulphide-type compound on the copper layer, and which is then contacted with a solution containing Cu ions to convert at least a major part of the crystalline layer to a stable copper sulphide film.  Cu is the preferred nucleating metal as having high optical transmission, but Ag, Cr, W or Pt may be used.  These low surface mobility metals are deposited by vapour deposition as a non-continuous coating of small individual islands. The Zn or Cd-sulphide type compound includes also selenides and tellurides and also mixtures of the type CdZn sulpho-selenide.  The final treatment with a Cu solution includes Cu acetate, chloride, sulphate, acetonyl acetate to which may be added a little hydrazine as reducing agent, and complexes e.g. pyridine, ammonia, quinoline, or thiourea dissolved in water, or alcohol or other polar solvent.  The flexible polymeric tape may be polyethylene terephthalate, of 100m  thick, or other thermo-plastic polymers e.g. polyvinyl chloride, poly-vinylidene chloride, poly-esters, and poly-carbonates. The Cu film is 2-12<\>rA thick, and the Zn/CdS film is 50-400<\>rA thick.  The coatings may be applied to the substrate moving at up to 50 metres per minute. Specifications 735,235, 738,285 and 820,777 are referred to.

Title: Traverse mechanism
IPC: B65H54/38
Filed: 1952-11-10
Abstract: 714,032. Winding yarn &c. CELANESE CORPORATION OF AMERICA. Nov. 10,. 1952, No. 28268/52. Class 120(2) Traverse mechanism comprises an element adapted to reciprocate in a traverse stroke, a traverse guide operatively connected thereto and an elastic member positioned in the path of the element at each end of the traverse stroke and adapted on being struck by the element to convert substantiallly all the kinetic energy of the element into potential energy of the member and then to reverse the direction of movement of the traverse guide. The yarn packages 31, 32 are formed on tube 29 held on a rack 28 driven by frictional contact with a cork-covered roll 15 which is belt-driven from a motor 19. The diameter of the belt-pulley 16 is regulatable at 21 to effect a speed-adjustment of the roll 15. The packages are prevented from "bouncing" by a dash-pot mechanism 36, 39, 41 and the pressure between them and the roll 15 is adjusted by a counterweight 34. Yarns 42, 43 are traversed by selfthreading guides 59, 61 connected to a permanent magnet 45, of cylindrical form, reciprocated between hollow solenoids 46, 47, into which the magnet passes to compress helical openings 52, 53, whose ends are held in blocks 49, 51. The magnet 45 is prevented from turning on its axis by a strap 56 which passes along a slot formed between a bracket 62 and a bar 63 and the guides 59, 61 are counterbalanced at 57. The solenoids 46, 47 are energized alternatively from mains 65, 66 through a commutator 71 and slip rings 72, 73 driven by a switching motor 67, comprising an armature 69 and feed coil 68, sparking of the commutator and slip ring being prevented by capacitors 79. A rheostat 81 is provided to change the frequency of the attraction and repulsion of the solenoids, carbonfilament lamps 82 being fitted in series therewith so that the current through them gradually increases during the starting-up period. A timing device 83 is included which opens and closes a contact 84 across a rheostat 85 in series with the armature 69 so that the motor speed varies to vary the frequency of the traverse and prevent ribbon-winding. A further contact 86 in the timing device may short a rheostat 75 in a voltage divider network 74, to increase the current in the coils 46, 47, or vice versa, as required. A resistor 80 is fitted in order that whichever coil 46 or 47 is repelling the magnet 45 the current therethrough is reduced in order to limit the demagnetizing effect on the magnet 45. In a modification, the elastic members are mounted upon the reciprocating element and are adopted to strike stationary abutments positioned in its path.

Abstract: 534,749. Measuring phase difference. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 26, 1939, No. 28780. Convention date, Oct. 26, 1938. [Class 37] [Also in Group XXXV] A condenser 29, across which a voltage depending on the phase difference between the output of an oscillator 10 and a reference oscillation is to appear, is charged through a rectifier 26 by impulses from a composite wave representing the source of the reference frequency, which may be that of a power line, and a frequency preferably in harmonic relation thereto derived by reduction from the oscillator. The condenser can discharge' where the amplitude of the composite wave falls, but only during the impulses. Between impulses the voltage remains constant. The discharge circuit includes a rectifier 31 and a resistor 36 ; its impedance remains high until the cut-off bias on the grid 33 is held off due to a connection from the oscillator through condenser 42 but is always high in relation to the impedance of the charging circuit. The voltage of condenser 29 thus changes with changes in the relative phase of the two oscillators. As shown the voltage of condenser 29 is arranged to vary the bias voltage of the grid of a variable-Á valve 46 acting as a reactive circuit in parallel with' the tuning inductance to control the oscillator. Specification 458,161, [Group XXXV], is referred to.

Title: Air Brake Cylinder with Slack Adjuster
IPC: B61H15/00
Filed: 1967-06-22
Abstract: 1,193,124. Air brake cylinder; slack adjustment. KNORR-BREMSE G.m.b.H. 22 June, 1967 [23 June, 1966], No. 28961/67. Headings F2E and F2F. An air brake cylinder for a railway vehicle disc brakes, is provided with automatic slack adjustment and is resiliently and pivotally supported on brackets extending from the vehicle frame. Automatic slack adjustment.-This is provided in the coupling between a non-rotatable tubular piston-rod 4 and a non-rotatable push rod 11 connected to the brake rigging and disposed with the rod 4. The coupling comprises an abutment ring 13 fixed on the inner surface of rod 4, and nuts 14, 15 screwed on to the push rod 11 on each side of the ring 13. The lead of the screw threads makes the nuts non-self-locking. A spring 16 and a thrust bearing 28 are axially clamped between nut 14 and an abutment at the open end of the piston-rod 4 urging the nut against the ring 13. The nut 15 is urged against the ring 13 by a spring 20 disposed between the piston head 3 and a non-rotatable axially movable control ring 23 abutting the nut. The spring 20 prevents axial play of the rod 11 within the nut 15 and absorbs vibration transmitted from the vehicle to the push rod 11. A spring 21 axially clamped between the nut 15 and control ring 23 together with spring 20 holds the nut 15 frictionally engaged with ring 23 preventing rotation of the nut during braking. The piston 3 and rod 4 move to the left (as shown) to apply the brakes, push rod 11 being moved by abutment ring 13 and nut 14, the ring 13 being moved along by spring 21. When the braking stroke of push rod 11 exceeds a normal braking stroke the forward movement of the control ring 23 is stopped by an abutment in sleeve 19. As the push rod continues to move, spring 21 will oppose further movement of the nut 15 together with the push rod, and will yield sufficiently to permit nut 15 to lose its locking engagement with the ring 23. Thus nut 15 will be rotated by the spring 21 and displaced axially to the right (of drawing). When the braking movement of rod 11 ceases the nut 15 is again locked against rotation. During return of piston 3 to its brake release position (as shown), the rod 11 will move with respect to the pistonrod 4, to take up slack. Mounting.-A substantially horizontally orientated bolt 31 passes through metal plates 32, 33 extending from the vehicle frame, and through a bore in a bracket 35 extending from the brake cylinder. Within the bore are metal rings 36, 34 between which are rubber rings 29 separated axially by a metal bush 30. Reference has been directed by the Comptroller to Specification 1,144,685.
