Title: Improvements in Ring Spinning and a Yarn Twisting Head for Ring Spinning Frames
Inventor: SUBRAMANIAN TARACAD ANANTAPADM
IPC: D01H13/08
Filed: 1965-12-06
Abstract: 1,169,699. Twisting apparatus. AHMEDABAD TEXTILE INDUSTRY'S RESEARCH ASSOCIATION. 8 Nov., 1966 [6 Dec., 1965], No. 51650/65. Heading DID. A twisting device, particularly for use in ring spinning &c., apparatus to strengthen yarn leaving the delivery rollers of the drafting head and to reduce the tension in the yarn, comprises a tube with two arms ending in yarn guides extending from diametrically-opposed points at its lower end, the guides being so arranged relatively to the end of the tube that when the tube is vertical yarn passing from the tube to one of the guides takes a horizontal path. In use, the device replaces the upper yarn guide in ring-spinning &c. apparatus, and is mounted to rotate in bearings in a housing 3. The latter is mounted on a shaft 4 which is screwed into the lappet-holder and is adjustable so that the device can be centred relatively to the spindle.The arms are of wire and the guides take the form of loops. Yarn passes from the delivery rollers through the tube, over its lower end 6 to one of the guides, and then to the traveller. As the latter rotates, the tube is also rotated so that a strengthening twist is imparted to the yarn between the roller and the edge 6. As the yarn changes direction as the yarn rotates, the spinning-tension is reduced.

Filed: 1972-11-09
Abstract: 1338730 Detecting gases electrically BORGWARNER CORP 9 Nov 1972 [28 Dec 1971] 51769/72 Heading G1N A breath alcohol testing system includes a normally balanced bridge circuit having first and second substantially identical alcohol sensing elements, such as heated catalyst resistances, in adjacent arms. First and second substantially the same samples of deep breath are obtained and the first sample is supplied directly to the first sensing element simultaneously with the second sample being supplied via an alcohol removal stage, such as a heated platinum wire to the second sensing element. Thus the effect of carbon dioxide and water in the two samples on the sensing elements is balanced out in the bridge. The bridge unbalance is indicated on a meter or by a lamp which is illuminated when the alcohol concentration in the first sample exceeds a predetermined level. The sensing elements may be of the ionization or semiconductor type.

Abstract: 1,157,578. Valve for hydraulic braking systems; Valves. GOODYEAR TIRE & RUBBER CO. 21 Nov., 1966, No. 52042/66. Headings F2F and F2V. [Also in Division G3] A pressure control valve 6 for hydraulic braking systems comprises a housing 15 having connected thereto a brake line 8, a pressure line 22 and a sump line 7. A power valve 17 is slidably mounted in the housing and has a null position in which all the lines are isolated from one another (Fig. 3, not shown). The valve 17 is movable in one direction to connect the brake line 8 and pressure line 22 and in the other direction to connect the brake line 8 and sump line 7. The movement is controlled by a spring-loaded pilot valve 16 which in turn is controlled by a solenoid 20 deriving its energy from an anti-skid device (Fig. 1, not shown). In the solenoid inoperative position fluid pressure passes from line 22 through a passage 31, filter 33, passage 34, chamber 35 and passage 28 to a first pressure chamber 30 to urge the valve 17 in the one direction. Pressure builds up in a chamber 25 and passes through a passage 40 in the valve 17 into a second pressure chamber 41 to balance the pressure acting on the valve and hence urge the valve back to its null position. On half actuation of the solenoid (Fig. 3, not shown), the valve 17 is in its null position and the pressure line is connected to the sump line through the pilot valve. With the solenoid fully actuated (Fig. 4, not shown), the pressure line is cut off from the pressure chamber 30 which is connected to the chamber 27 from which the sump line extends. Fluid from the chamber 30 enters chamber 27 and chamber 41 to urge the valve 17 in the direction to connect the brake line and the sump line. The ends of the pilot valve are maintained at the same pressure by a passage 38 which is also connected to the sump line.

Title: Protective adhesive carrying tape
IPC: A61K6/893
Filed: 1973-11-16
Abstract: The adhesive strip is used for producing resistant protective coatings on substrates such as letterings. The main constituent of the adhesive composition applied on one side of a thermoplastic carrier film is polyunsaturated ester which contains urethane or urea groups and is free-radically polymerisable with crosslinking. This ester is a multiple ester of monocarboxylic acid containing the grouping CH2=C-COOH; it has the constitution of a reaction product of       A) an organic polyisocyanate with B) a polymerisable monomer which is an ester of said monocarboxylic acid. For the reaction with an isocyanate group of A) the ester B) contains a hydroxyl or nontertiary amine group in the radical of the hydroxyl compound with which said monocarboxylic acid is esterified.   For curing using UV radiation the adhesive composition may contain a UV-activable polymerisation initiator and be applied to a UV-transmitting carrier film. Instead it may also incorporate an amine as co-reactant for a peroxide activator to be applied to the substrate surface before the strip is applied. After the adhesive composition has cured, the carrier film can be peeled off.
