Title: A process for the treatment of filaments, fibres and fabrics, especially carpets
IPC: D06M13/507
Filed: 1961-07-10
Abstract: Filaments, fibres and fabrics are treated with a solution in an organic solvent, e.g. trichlorethylene or perchlorethylene, of (a) at least one alkyl titanate of the formula Ti(OR)4 in which R is an alkyl radical and (b) colloidal silica or methyl or ethyl silicate, and dried at a temperature between 60 DEG  and 160 DEG C. to improve their resistance to wear, to protect them against dry soiling and to render them water repellent.  Specified alkyl titanates are butyl, isopropyl and octyl titanates and the solution may also contain ricinyl and/or phenyl titanates.  The solution preferably contains 1-20% by weight of the alkyl titanate and up to 7% by weight of colloidal silica or methyl or ethyl silicate.  Filaments, fibres or fabrics made from wool, jute, flax, cotton, viscose rayon, nylon or acrylic fibres, e.g. carpets, moquettes and velvets, may be treated.

Title: Improvements in machines for cutting teeth in gear wheels
IPC: B23F1/04
Filed: 1920-08-30
Abstract: 169,891. Sykes, W. E. Aug. 30, 1920. Gear-cutting. -Gear-generating machines of the type employing one or more pinionshaped cutters have means comprising guides inclined to the cutter axes for withdrawing the cutters from the work during the return stroke. In a machine of the kind described in Specification 118,555 for generating double helical gears, the cutters a, b carried respectively on spindles c, d mounted in housings e, f are driven through worm gearing from a shaft g and are controlled by helical guide screws working in guide nuts j, k. The carriage b is reciprocated from a crank disc m, and carries two saddles p having inclined guide faces cooperating with similar faces on flanges o integral with the housings e, f. Stops p<2> on the saddles which transmit the reciprocating movement to the spindle housings are arranged at a distance apart greater than the width of the flanges o so that at the beginning of each stroke the carriage will move through a short distance without axially moving the spindle housings. During these periods the inclined guides will cause the cutter spindles to move laterally to impart the required relieving movement and to return to operative position for the next cut. In order to prevent axial movement due to friction while the stops p<2> are out of action at the end of the cutting stroke of each tool, the spindle housings are held by means of cam levers q having cam faces adapted to cooperate with abutments on the spindle housings and mounted on a rock shaft r operated by link mechanism from a second rock shaft t actuated from a cam t<6>. The movement of the cam levers is timed to disengage before the commencement of the cutting stroke, the friction of the angular guides being then overcome by springs. To avoid' strains due to the lateral displacement of the cutter spindles, the cutter controlling mechanisms are slidably mounted on a bracket u and are alternately actuated in unison with the relieving movements of the cutter spindles by cams v on a rock shaft v<1> operated by link mechanism from the shaft t. The return movements are effected by spring abutments x.

Abstract: 917,979. Weighing-apparatus. BLUNDELL & CROMPTON Ltd., and CROMPTON, H. E. July 13, 1961 [July 18, 1960], No. 25046/60. Class 143. Weighing-apparatus comprises air pressure actuated lifting means supplied by a pump, a relief valve which operates when the article to be weighed has been lifted to relieve the air pressure so long as the article remains lifted above a predetermined amount and an indicator for indicating the air pressure applied to the actuating means. Conveniently, the indicator may be adapted to give direct readings of weight. The article 30 to be weighed, e.g. a gas cylinder, is placed on a platform 31 which is hinged at 32 and rests on a base 34 projecting from the plate 35 which constitutes the cover of a cylinder 37. A pump 42 is operated and sends air through a non-return valve 43, 44 and pipe 41 into the cylinder 37, whereby the plate 35 is raised and the platform 31 tilted until air escapes past a seal 36. The indicator 45 is then read, being calibrated to show weight allowing for the proportion borne by the hinge 32. Pressure is released by a valve 46. The platform may be the top of a piston in a cylinder and carry the whole weight, air escaping when the piston uncovers a port in the cylinder wall. Alternatively bellows may be used.

Abstract: 359,571. Valve amplifying circuits. HAZELTINE CORPORATION, 15, Exchange Place, New Jersey, U.S.A.- (Assignees of Wheeler, H. A. ; 78, 22nd Street, Jackson Heights, New York, U.S.A.) April 23, 1930, No. 25349/31. Convention date, June 20, 1929. Divided on 359,890. [Class 40 (v).] In a high-frequency amplifier the output impedances of successive amplifier stages are rendered capacative over the operating range by the use of a large neutralizing condenser. The input circuit from an aerial may thus be made approximately equal in capacity to the neutralizing capacities C2 so that the same coupling may be used for input and intervalve couplings and the tuning condensers can be ganged. The coupling are preferably of the type described in Specifications 273,639 and 315,399, [both in Class 40 (v), Wireless signalling &c.]. The Figure shows a mixed intervalve coupling in which condenser C3 couples the plate of the valve to a tapping on the secondary inductance L1 and the sense of the tuned primary winding L3 is reversed. The winding L2 serves for neutralizing only and the circuit L3, C3 is tuned to a frequency just below the lowest frequency in the operating range. In a modification, Fig. 1 (not shown), the neutralizing winding also serves as a primary winding to the transformer. Winding dimensions and inductance valves are given in the Specification. Specifications 359,890 and 359,901, [Group XXXV], are also referred to.

Abstract: 865,635. Vehicle power steering. BOULTON PAUL AIRCRAFT Ltd. Aug. 1, 1958 [Aug. 12, 1957], No. 25417/57. Class 79(5). In a hydraulic servo system for steering &c. the control valve 40 operated from the steering wheel through a reversible worm drive 42, 43 is mounted within the movable actuating piston 25 and has the pressures on opposite sides of the piston 22 imposed across it to piovide feel and permit self-centering by castoring action, the valve 40, in its rest position permitting flow to apply equal pressure loads at opposite ends of the piston 25. The steering column 2 is rotatably mounted on a bearing 10 in the end of a cylindrical sleeve 3 and is located against endwise movement by a flange 12 and ring 13 engaging, the inner bearing race. The end of the column 2 is supported by a ball race 5 in the sleeve 3 and carries internal worm teeth 43 for actuating a worm 42 which is coupled to the valve 40 through a rod 41 and link or ball joint 41a. Rotation of the worm 42 is prevented by splines 44 which are engaged between a shoulder 45 and a ring 48 fixed within a hollow piston rod 23 and which permit limited axial movement for operating the valve 40 and act as stops for manual operation in the event of an hydraulic breakdown. Rotation of the piston 25 within the cylinder 19 is prevented by the engagement of splines 35 on the hollow piston rod 23 engaging grooves 36 in a fixed liner 37. The valve 40 is slidable within a cylindrical liner 39 having ports 64, 65 opposite lands 62, 63 and connected to opposite ends of the operating cylinder through passages 67, 71. In the rest position the lands are arranged to leave the ports partially open so that equal pressure loads are applied to opposite ends of the actuator. Pressure fluid is supplied to the central annular channel 61 through a coupling 82 and passage 83 and is exhausted from spaced annular passages 59, 60 through ports 78, 79, leading to a central bore 75 in the valve 40 from which the fluid escapes through an end port 80 and coupling 81 A. Reduced ends 54 of the valve 40 are slidable in sleeves 53, 55 and provide annular passages 69, 73 which are pivoted to the cylinder passages 67, 71 to provide "feel". The effect of feel is further supplemented by a spring 51 engaged between a sleeve 49 and collar 52 on the operating rod 41.

Abstract: 532,609. Washing machines with closed receptacles and liquid &c. supply encased. UNITED STATES HOFFMAN MACHINERY CORPORATION. Sept. 11, 1939, No. 25602. Convention date, Oct. 29, 1938. [Class 138 (ii)] A laundry washing machine comprises an oscillatory drum with an imperforate periphery and having liquid supply means at one end and continuous liquid discharge at the other end, a partition adjacent the liquid supply end to provide a receiving chamber for water and washing ingredients, conduits extending from the receiving chamber to convey liquid at a uniform rate in all parts of the drum, and a perforated discharge end engaging an enclosing stationary head. The drum 17 is mounted by trunnions 15, 16 in end frames 11, 12 and is rotated in opposite directions alternately by a reversing motor driving through a chain and gear or wheel 37 fixed to the drum. Hot and cold water, and if desired cleansing agents from a hopper 136 are introduced through the inlet 29 into a chamber 30 between the drum end 26 and a partition 27 and passed through apertures 34 into conduits 31 projecting inwardly from the periphery and extending to the perforated rear end 28 of the drum which is housed in the hollow frame 12. The liquid escapes through apertures 35 in the conduits to the clothes in the drum, even distribution being effected by increasing the apertures along the conduits which. act as tumblers for the clothes in the washing operation. Flexible sealing flaps 42 and 53 bear against a flange at the end of the drum to prevent escape of liquid and vapour respectively at the periphery. The liquid continuously escapes through the apertures in the end plate 28 of the drum into a chamber 72 fitted with a sump valve 60 and communicating with a chamber 74 containing a float 93 carried by an arm 80 pivoted on a vertically adjustable slide or weir 78 on the side of the chamber 74 whereby the float can be adjusted for operation at different working levels of liquid in the drum as for example when washing and rinsing respectively. The float lever 80 is connected through lever 88 and a link to an arm slidable on a square shaft 89 and when the float approaches its lowest position the shaft 89 is rotated sufficiently to operate valves for introducing a flush of fresh liquid, or recirculating the liquid back by the action of a steam injector connected with the pipe 76 to the inlet 29, this being arrested as the float rises to its highest position. Liquid is led away from the slide or weir chamber by a pipe conectend to a channel 121. The sump valve 60 which is normally closer is operable by a foot lever 69, which when actuated to open the valve acts through link 134 and lever 133 to close a valve 132 whereby a piston controller valve 110 in the supply system may open.
