Title: Process for making wool shrinkproof and feltproof
IPC: D06M11/54
Filed: 1960-04-28
Abstract: Wool is rendered shrinkproof and feltproof and may be bleached by impregnating it with an aqueous bromate liquor containing a wetting agent, freeing it from excess impregnating liquor by squeezing so that it has a liquor pick-up of 30-130% by weight, calculated on the air-dry wool, and successively treating it with an acid at a temperature of at least 25 DEG C., an aqueous solution of a reducing agent and an alkaline neutralizing agent.  The bromate may be an alkali or alkaline earth metal bromate, e.g. an aqueous solution containing 20-80 g. per litre of potassium bromate, and the bromate solution may contain at least one alkali or alkaline earth metal chloride.  The acid which may be inorganic, e.g. hydrochloric, sulphuric and perchloric acids, or organic acid may be applied by immersing the wool in the acid, by spraying the acid on to the wool which may be warmed by means of infra red lamps or in the case of volatile acids, e.g. gaseous HCl, by exposing the impregnated wool to the gaseous or vaporous acid.  The reduction is preferably carried out at 30 DEG -50 DEG C. with dilute aqueous solutions containing 0,-1% by weight of the reducing agent, e.g. alkali metal sulphites, bisulphites, thiosulphates and hydrosulphites, and the wool is then neutralized with, for example, dilute aqueous ammonia or a dilute aqueous solution of an alkali metal carbonate or bicarbonate.  The handle of the wool may be modified by after treating it with an aqueous soap solution at 30 DEG -50 DEG C. and the wool may subsequently be dyed.  Any bromine produced during the acid treatment of the wool may be removed by bubbling a stream of air through the acid bath or by recirculating the acid bath through a column in countercurrent with a stream of air.  The wool may be in the form of tops or loose fibres, yarns or woven or knitted fabrics, blankets or felts, alone or in admixture with natural, artificial or synthetic fibres, e.g. cotton, viscose rayon, polyamide, polyester and polyacrylic fibres.  Specifications 614,271 and 798,236 are referred to.

Abstract: 803,757. Hydraulic locking of double-acting jacks. BRITISH MESSIER, Ltd. May 22, 1956 [May 24, 1955], No. 14990/55. Class 69 (2). A double-acting jack 10 is locked hydraulically if the pressure supply fails. Liquid from an accumulator 45 passes via a pipe 46 and a valvecontrolled chamber 23b to a distributing valve 16 and then via one of two passages 36, 37 to an isolating valve 33 and through one of two further passages 38, 39 to the jack. The valve 33 is loaded by a spring 29 which moves the valve 33 if the pressure fails, thereby closing a passage 23 from the pipe 46 and also closing the passages 38, 39 so that liquid on both sides of the piston 12 of the jack is trapped. A pump 47 connected to a reservoir 42 maintains the pressure in the accumulator via a cut-out valve 48. A non-return valve 50 is provided in the return line from the jack to the reservoir.

Title: Improved process for the manufacture of cinematograph films
IPC: G03D15/00
Filed: 1921-05-30
Abstract: 186,649. Coppier, A. C. May 30, 1921. Kinematograph picture films; composite photographs; studio accessories.-A process for producing a composite film from stock negative films consists in projecting simultaneously the desired portions of the negative films upon a wide sensitized paper strip, thereby producing an enlarged print, retouching the print, ard producing therefrom by photographic reduction the composite negative film from which positive kinematograph films are printed. Films in colour may be produced by colouring, the enlarged print with the predominant colour, for instance, blue, superimposing on this in turn transparent strips upon which the remaining colours, for example, red and yellow, are respectively applied by colourists, producing colour-value negatives from these strips by reduction, and producing from these negatives printing strips which are employed to print the respective colours upon a positive film, produced as in the first part of the process, after this film has been coloured with the predominant colour. The stock films may comprise background films, and acted scenes of any kind, the actors performing, if desired, in front of a transparent screen upon which a moving background picture is projected from the rear. The enlarged prints may be produced on gelatino-bromide paper 20-30 cm. wide. The transparent strips on which the colourists apply the colours may be composed of celluloid or cellulose acetate. The colours may be printed on the film by phototype printing in varnished lake colours.

Title: Improvements in or relating to methods of and apparatus for applying settable material to a surface
Inventor: MARKLEW ARTHUR LESTER
IPC: B05C5/02
Filed: 1957-05-14
Abstract: <PICT:0888768/III/1> A settable material is applied to a surface by continuously moving the outlet orifice of a nozzle positioned at one end of a nozzle body mounted on a support and containing a quantity of the material relatively to the support, in a predetermined path over and close to the surface, and controlling the flow of material from the nozzle at its point of emergence therefrom, in timed relation with the movement of the nozzle.  As shown, a nozzle body 6 is mounted in gimbals on a suspension ring 2 carried by a plate 1. The upper portion of the body 6 contains a pneumatic cylinder 7 in which a piston 9 may be moved by compressed air admitted through passages 7a or 7b.  The piston 9 is attached to a needle 19 which controls the emission from a nozzle 12 of rubber compound, which is circulated under pressure through a lower chamber 6a in the body 6, through connections 6b and 6c.  The body 6 is articulated with a connecting rod 18 through a self-aligning ball journal 16.  As shown in Fig. 3, the plate 1 is mounted on pillars 20, and the ends of the connecting rod 18 are journalled on adjustable throw eccentrics 25 which are carried by shafts 22, which are interconnected by sprockets 24 and chain 23, and adapted to be driven by means 26.  Closures 27, to be lined, are brought successively into a fixed position below the nozzle which is caused to describe a circular motion while the needle-valve in its tip is opened by the admission of compressed air beneath the piston 9.  The apparatus may be adapted to move the nozzle in non-circular paths, e.g. square, rectangular or oval. Several nozzles with a common connecting rod drive, may be mounted on the plate 1.

Title: Improvements in or relating to electric switches and switchgear having auxiliary sparking contacts
IPC: H01H9/38
Filed: 1941-11-27
Abstract: 553,638. Arc-rupturing in switches. BROOKHIRST SWITCHGEAR, Ltd., and HARRIS, R. C. Nov. 27, 1941, No. 15273. [Class 38 (v)] The movable arcing contact 20 of an air or oil-break switch is mounted on a bellcrank lever 16 which is pivoted at 23 to the main movable blade contact 14 and carries a weight 22 or is formed as a damping air vane or paddle. Owing to inertia effects in opening and closing, the lever 16 is caused to lag behind the blade 14, so causing the tip 20 to travel in a loop 24 whereby it acts as a spark-taking, contact in opening circuit, but in closing circuit engages the fixed arcing contact 15 after the main contacts engage, and at a different point on the contact 15 from that whereat it separated. The pivot position is also such that the contactpressure between 20, 15 is reinforced electrodynamically by the current loop comprising arm 19 and the blade extension. The switch may be snap-operated and can function even if tilted backwards or forwards by 45 degrees. In Fig. 1, centrifugal force tends to assist inertia-effects in closing, but in Fig. 4 the arrangement is such that centrifugal force acts in both directions as shown by the arrows 25 and radial line 26. The Specification refers also to the weight being shaped as a wind vane and paddle in air-break and oil-break switches, respectively.

Title: Improvement in multiple spindle lathe
IPC: B23K1/00
Filed: 1944-02-10
Abstract: 593,747. Lathes. CONE AUTOMATIC MACHINE CO., Inc.. Feb. 10, 1944, No. 15361. Convention date, Dec. 19, 1942. Divided out of 593,737. [Class 83 (iii)] A multiple spindle lathe in which the movements of the work and tools are controlled by a cam-shaft which may be driven through variable speed gearing at a relatively fast speed in either forward or reverse directions or at a relatively slow speed in the forward direction, is provided with an interlocking device for ensuring inoperative condition of the gear elements for movement in the reverse direction when the gear elements for movement at fast speed or slow speed in the forward direction are selected and vice versa. A gear 58, Fig. 4, mounted on a driven shaft 51 carries one part of a clutch with external teeth 64 meshing with a gear 70 on a shaft 71, so that on engagement of the clutch parts 64, 65 through the action of a yoke 66 secured to a rock-shaft 67, the cam-shaft 32 is driven at a high speed from the shaft 71 through a worm 72 and worm-wheel 73. When the clutch 64, 65 is disengaged, the shaft 71 may be driven in the reverse direction through a gear 59, Fig. 5, meshing with the gear 58 and carrying a clutch part 75 also meshing with the gear 70. The clutch 80 of this reverse drive is also operated from the rock-shaft 67. The cam-shaft may also be driven at a selected low working speed from the shaft 51 through change gears 90, 91, shaft 92, gears 93, 94, shafts 95, 102, 105, all of which are connected by change gears, and worm 108 meshing with a worm-wheel 109 which drives shaft 71 through an over-running clutch device 110 and a clutch element 113 operable from the rock-shaft 67. The clutch parts 64, 75 and 113 may be operated manually from either the back or front of the machine by levers 142, 133, 159 coupled to levers 145, 130, 162 by rods which carry abutments 174, 176, 177 adapted to co-operate with a pivoted lever 170 to ensure that the forward drive and the reverse drive clutches are not engaged at the same time. The rock-shaft 67 is normally actuated from the cam-shaft 32 to control the high speed clutch and on the disengagement of said clutch, the shaft 71 is slowed down. to the lower speed rate by means of brake shoes 122 applied to the gear 70 by the action of a cam-operated rock-shaft 125. The lathe is more fully described in Specification 593,737. Specification 528,694 also is referred to.

Title: Nuclear Reactors
Inventor: MARTIN DUDLEY JAMES VICTOR
IPC: G21C7/30
Filed: 1968-03-29
Abstract: 1,185,780. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 7 March, 1969 [29 March, 1968], No. 15373/68. Heading G6C. A nuclear reactor has two members reciprocable within a channel by a drive mechanism disposed outside one end of the channel, the members and drive mechanism being connected end-to-end in series by releasable couplings, and means being provided for selectively releasing the couplings within the channel to enable withdrawal of one or both members from the other end of the channel. In a steam-generating, heavy water-moderated reactor (Fig. 1), the fuel channels 1 are arranged in six groups of seventy-two and one channel of each group is of the kind designated 1a. This contains four fuel clusters 12 stacked end-to-end to comprise a member 2, the fuel in these clusters having only natural abundance of U-235. A member 3 comprises a fuel cluster in which the fuel is enriched in U-235 to C o  value 6.5. The fuel is UO 2  sheathed in Zr alloy. The members 2, 3 and a drive mechanism 4 are connected end-to-end by releasable couplings 5, 6. Coolant enters the lower end of each channel 1 and enters each channel 1a by a branch pipe 8. It leaves the channels 1, 1a through branch pipes 9 and passes to a steam drum where the steam and water are separated, the steam being conducted to a turbine. The heavy water moderator is contained in a calandria vessel 10 surrounded by shield tanks 11 each containing ordinary water. In the channels 1 the fuel clusters 12 are suspended from a closure plug 14 for the upper end of each channel by a tie rod 15, and between each plug 14 and the fuel clusters there is a steel baffle 16 for preventing neutron streaming. In the channels 1a the fuel clusters 12 are supported by the member 3 and drive mechanism 4 and they are surmounted by a steel baffle 16a. The upper end of the baffle 16a is guided by rollers 37 and the lower end has an oblique face 38 complementary to an oblique face of the upper end of the member 2. The oblique faces provide a sideways component of force for urging the member 2 into contact with the channel wall to prevent rattling. The reactor is not reactive when the coolant is wholly liquid and in order to initially activate the reactor, the members 2, 3 in each channel 1a are raised to insert the enriched fuel of the members 3 into the moderated region of the reactor. Thereafter, reactivity can be controlled by varying the position of the members 3 in the reactor. When it is necessary to withdraw the members 2, 3 the coupling 6 is released. Sometimes only the natural fuel needs to be withdrawn in which case only coupling 5 must be released. In an alternative embodiment (not shown), at least one of the members comprise neutron absorbing material for controlling reactivity of the reactor by positional variation in the channel by the drive mechanism.

Title: Improvements in sewing machines
IPC: D05B57/30
Filed: 1934-05-23
Abstract: 419,924. Sewing machines. HULME T., and CARRINGTON & SONS, Ltd., S. R., Cale Green Hat Works, Stockport, Cheshire. May 23, 1934, No. 15376. [Class 112.] The hook of a lock-stitching machine oscillates about a horizontal axis in a plane at an angle to the feed direction. The machine has two needles co-operating with the same hook. Rotation of the main shaft 4 causes the rod 7 to oscillate the spur wheel 9 thereby rocking the shaft 15 through the intermediate wheels 11, 14 of suitable ratio. The rocking motion of the shaft 15 is transmitted to the hook 20 by a pair of bevel wheels. Owing to the play in the transmission mechanism, the hook dwells at each change in the direction of motion, allowing time for the needle loops to be formed and brought into correct position for reception by the hook on its next oscillatory swing.

Title: Improvements in or relating to control systems
IPC: G05F1/00
Filed: 1936-06-03
Abstract: 477,831. Automatic control systems. BAILEY METER CO. June 3, 1936, No. 15506. Convention date, June 19, 1935. [Class 38 (iv)] [Also in Group XXIX] Fluid pressure &c.-A regulating system in which a variable is controlled or regulated through a hydraulic transmission device of variable transmission ratio comprises means for producing an initial variation in said transmission ratio in accordance with variations in said variable and additional means for producing a continuing variation in said transmission ratio until said variable returns to normal. Variation of the transmission ratio may be effected by employing a hydraulic coupling, the filling of which can be varied. The apparatus shown in Fig. 4 comprises a hydraulic coupling from which liquid passes through a scoop tube, pipe 13 and a cooler, and to which it returns through a pipe 15. The quantity of liquid in the coupling is varied by driving the pump 18 in one or the other direction to supply or withdraw liquid. The control of the pump motor 79 is effected by a switch 82 actuated by diaphragm motors 81, 83 respectively supplied with pressure from the relay 43 and the compressor 65. An intermittent switch 88 operated by a motor 89 is provided. In the form shown in Fig. 7, the valves 24, 25 are controlled by electrical means. The Bourdon tube 34 may vary the position of a pivoted beam 90 supported by a vertically movable carriage 92 to interrupt one or the other of the opposed fields 98, 99 of a reversible motor 100. The motor is thus driven in one direction or the other to raise or lower the carriage until the broken circuit is re-established. The beam also acts through relays 103, 104 to control a motor 105 adapted to position a floating lever 107, and a beam 106 with contact 108 for controlling the circuits of a reversible motor 112 which actuates the valves 24, 25. The driven shaft. 3 drives a generator 113 which actuates an arm 115 for restoring the lever 107 and beam 106 to initial position. The motor 100 also actuates a cam 116. When the carriage 92 is out of its neutral position, the cam tilts a mercury switch 118 in circuit with a periodic interrupter 119 and the motor 105, so that the valves 24, 25 are periodically operated until the carriage and Bourdon tube have returned to their initial positions. In modifications of this form, the arm 115 is actuated by means including a potentiometer adjusted in accordance with the liquid level in the reservoir 17 or the pressure in the pipe 13.
