Title: Improvements in the Treatment of Wool
Inventor: WRAY DENNIS
IPC: D06L4/24
Filed: 1966-07-29
Abstract: 1,192,553. Shrinkproofing wool. PRECISION PROCESSES (TEXTILES) Ltd. 28 July, 1967 [29 July, 1966], No. 34288/66. Heading D1P. Wool, e.g. in the form of top, wool serge or knitwear, is shrink-proofed and rendered antistatic by substantially uniformly treating it with an aqueous solution of hypochlorous acid at an acid pH to modify it to such an extent that there is a reduction in shrinkage, when compared with art untreated control which is subjected to the same washing test, of at least 15%, then substantially uniformly impregnating it with a water-soluble cationic hydrophilic resinous condensation product which is obtainable by (a) reacting a mono-and/or polyfunctional derivative of a polyalkylene oxide with a polyamine in such proportions that the resulting polyamine contains a plurality of reactive hydrogen atoms each of which is attached 'to a nitrogen atom and (b) then reacting the product with at least one bifunctional compound containing at least one epoxide or alpha-halo-betahydroxyalkyl group, at least the latter part of the treatment with the cationic hydrophilic resinous condensation product being carried out under alkaline conditions, and then heating it e.g. at 70-120C. The aqueous solution of hypochlorous acid may be obtained from an aqueous solution of an alkali metal dichloroisocyanurate to which an acid has been added, a solution of dichloroisocyanuric acid in aqueous tetrasodium pyrophosphate which has been acidified or an acidified solution of a hypochlorite, and the treatment with hypochlorous acid is preferably applied from a short liquor bath having a pH of 3-6 to which permonosulphuric acid or an alkali metal salt thereof and a wetting agent, e.g. a condensation product of trimethyl nonylphenol with 6 moles of ethylene oxide, may be added. After treatment with the hypochlorous acid the wool may be treated with an aqueous bath containing sodium sulphite. The cationic hydrophilic resinous condensation product may be prepared by the reaction of ethylene diamine, diethylene triamine, triethylene tetramine, dipropylene triamine, paraphenylene diamine or 1,4- diaminio-cyclohexane with a polyethylene oxide or polypropylene oxide having 3-70 ethereal oxygen atoms and a molecular weight of 400- 2,000 the terminal hydroxyl groups of which have been reacted with phosgene, chlorosulphonic acid, epichlorohydrin or a compound forming a sulphuric ester grouping, in the presence of boron trifluoride or stannic chloride, the resulting product then being reacted with epichlorohydrin, dichlorohydrin or polyalkylene glycol bis-chlorohydrin ether. The cationic hydrophilic resinous condensation product may be applied to the wool from a bath having a pH of 7-10 which may contain an anionic wetting agent, e.g. the sodium salt of a sulphated fatty alcohol.

Title: Improvements in Brake Adjusters
Inventor: FARR GLYN PHILLIP REGINALD
IPC: F16D65/56
Filed: 1966-07-30
Abstract: 1,198,443. Disc brakes; ratchet gearing. GIRLING Ltd. 28 July, 1967 [30 July, 1966], No. 34331/66. Headings F2E and F2Q. In a disc brake having a brake pad assembly 12, 14 (Figs. 1 and 3) capable of limited circumferential movement in the caliper and a cooperating brake pad assembly 16, 18 selectively displaceable in a brake applying direction from a normal rest position by actuating means, a unidirectional drive means 32, 40 for effecting adjustment of the rest position during brake release in a brake applying direction is provided responsive to circumferential movements of the pad assembly 12, 14. Automatic brake adjustment is obtained when the thrust member 36 is actuated by hydraulic cylinder 24 or hand brake lever 56 via push rod 62, rubber block 64 and thrust pad 66. The thrust member 36 presses pad 18 and by reaction pad 14 against the rotating disc (not shown). This causes back plate 12, which has circumferential slots 22, to move circumferentially so that the arm 40 moves to the right (Fig. 3). As the braking is released spring 44 moves the arm 40 to the left and if any wear has occurred a projection 42 rotates the ratchet wheel 32 and piston 28. The internal bore of the piston 28 is screw threaded to the thrust member 36 which is held against rotation by a flange 54 so that the member 36 is axially displaced towards the disc to re-set the normal position of the pads 14, 18. The arm 40 may have a flexible portion intermediate its ends or may be longitudinally slotted including a rubber or resilient button at the pivot point 41 or may be made of two sliding parts spring biased together so that the arm is yieldable in its longitudinal direction. Alternatively the pawl 42 may he provided by a lever pivoted to the arm 40 in the form of a bell crank lever which is spring biased towards a stop on the arm 40 and into engagement with the ratchet teeth. In a modified hand brake actuating arrangement (Fig. 4, not shown), halls (74) are arranged to ride up ramps between the cams (70, 72) when a brake lever (68) is turned. In an alternative embodiment (Fig. 5) hydraulically actuated by cylinder 100 or mechanically actuated by lever 120 acting by cam 118 on the end of a push rod 104, the normal rest position of the brake pad 18 is adjusted by rotation of the rod 104 which has an end 108 screw threaded within a nut 110. When braking an arm 122 moves a member 124 of a one-way clutch clockwise and the edge 116 of the nut abuts a friction ring 138. If any wear has occurred on release of the brake the member 124 which moves anticlockwise due to the action of spring 136 (Fig. 6), moves by means of balls 134 the rod 104 and since the nut 110 is held against the friction ring 138 the axial position of the nat and piston is adjusted to compensate for the wear. The automatic adjustment of the brake is restricted, by suitable choice of the spring 136, so that an hydraulic pressure in the cylinder 100 of 100 p.s.i. or greater is necessary to extend the spring 136 and move the clutch member 124.

The magazine is reciprocated by engagement of a cam 2 fast with it against a plate 12 provided this has been locked against movement by the electro-magnet e because an article has deflected the arm d. Labels may be delivered from opposite ends of the magazine alternately. Safety devices.-In the form illustrated the bottles b roll in engagement with a resilient surface g carried by a wall h which yields if the bottles jam.

Title: Improvements in envelope sealing machines
IPC: B43M5/04
Filed: 1920-12-06
Abstract: 175,467. Rogers, F. H., (Standard Envelope Sealer Manufacturing Co.). Dec. 6, 1920. Damping - machines. - In an envelopeclosing machine, the envelopes are piled face downwards in a holder 29 and are fed from it by an india-rubber conveyer band 20, the passage of more than one envelope at a time being prevented by a flexible stop 76 mounted so that its edge adjacent the fold of the envelope flaps is curved more abruptly that its opposite edge, which results in a rubbing action that does not tend to form a new folding line between the flap and the body of the envelopes. The envelopes are held on the band 20 by a spring strip 85 while the flaps are raised by a blade 92 pressed upon a damping-roller 95 by a pivoted arm 106. The rear of the envelope pile in the holder 29 rests on a triangular support 36 which is slidably adjustable to suit the length of the envelopes and is held by a spring 37. The conveyer rollers 10 are barrel shaped and are mounted, as shown in Fig. 4, upon studs 7 fixed at one end only in the machine frame. One of the rollers 10 is provided with an inset india-rubber band 24, Fig. 3, against which bears under the action of a spring 25, the roughened shaft of an electric motor 21 which is pivoted at 22 to the machine frame. Instead of this electric drive the rollers may be rotated by a hand-crank 18 which is inserted through the hollow stud 7 and screwed into a plate 14 at one end of the roller. The conical damping-roller 95 rotates in a sloping tank 93 pivoted at 87 to the machine frame, its lowest position being adjustable by a stop 90, and the upper surface of the tank is held in an approximately horizontal position by the whole machine being tilted upon adjustable feet 4. Water is supplied to the tank by an inverted bottle 99, the insertion of which without spilling the water is facilitated by a valve 102 which is opened when its stem is pressed upwards by meeting the bottom of the tank. The pressure of the arm 106 upon the flaps of the envelopes is adjustable by a stop 109. Clamping-screws 114 permit lateral adjustable of the damping-device.

Title: Improvements in or relating to fluid-pressure operated servo-motors
IPC: B62D5/087
Filed: 1953-12-10
Abstract: 810,471. Vehicle power steering. JOHNSTON, R. H., BISHOP, R., and WHITLOCK, G. B. R. March 9, 1955 [Dec. 10, 1953], No. 34462/53. Class 79(5) [Also in Group XXIX] In a spool valve for controlling a doubleacting, piston and cylinder servomotor in a power-assisted vehicular steering mechanism, comprising a valve spool 1 displaceable in either direction from a central position in a casing 6 having a pressure port 14 flanked by exhaust ports 13, 15 and ports 19, 20 connected to opposite ends of the cylinder and wherein at or near the central position of the spool communication is established between the pressure port, both exhaust ports and both sides of the piston, a further port 25 co-operable with a further spool land 21 is provided to reduce the time to return the piston to its mid cylinder position on the release of the steering wheel after a steering operation. The port 25 is connected to the passage supplying the pressure port 14 with pressure fluid, and when the spool is in its central position with the exhaust port 15 through a reduced diameter portion 23 of the spool so that the pressure in the port 14 is reduced to that prevailing at the exhaust port 15. On the piston returning to its mid cylinder position, pressure fluid displaced from one side of the piston flows to exhaust by way of the appropriate exhaust port 13 or 15 and also the respective marginal portion of the pressure port 14 whilst make-up fluid for the other side flows by way of the appropriate exhaust port and the other marginal edge of the pressure port so that the flow rate through the valve is approximately doubled to what it would otherwise have been. The valve spool is returned to its central position, e.g. by springs, and the piston by, e.g. castoring action of the steerable road wheels. To reduce the tendency of the spool to flutter as it approaches its end positions communication between one or other of the ports 19, 20 and the respective exhaust port is cut prior to the cutting of communication between the ports 25, 15. To maintain a predetermined low pressure in the pipes between the spool valve and the cylinder, spring-loaded, non-return valves opening towards the low pressure region are interposed in the exhaust lines from the ports 13, 15.
