Title: Method of braking a bobbin chuck mounted on a pivotal arm and an apparatus for implementing the method
IPC: B65H63/036
Filed: 1975-10-07
Abstract: 1528805 Braking a yarn bobbin chuck MASCHINENFABRIK RIETER AG 7 Oct 1975 [9 Oct 1974] 40974/75 Heading D1J To brake a bobbin chuck and release the bobbin thereon, the rotating bobbin chuck is moved against a brake shoe which then moves in the same direction as the chuck, the brake shoe is pivoted about an axis under the effect of a braking force, and after the bobbin has come to a standstill the brake shoe pivots in an opposite direction under the effect of a pneumatic force while the pneumatic force is imposed on releasable holding means of the chuck to release the bobbin. Thread 2, Fig. 1, is wound by friction drive drum 3 on tube 5 on chuck 6. Tube 5 is held, Fig. 2, on chuck 6 by ring 9 expanded by cone 10 biased by spring 34 acting on piston 32. When the thread is wound, device 7 pivots arm 8 against stop 25 so that chuck cylinder 11 engages brake lining 13 and moves brake shoe 12 back over piston 16 so that air in chamber 17 is forced back into pressure source Q. The braking moment M, Fig. 3, causes element 15 carrying piston 16 to pivot about hub 14 so that shoe 12 is pressed against stop 26 and piston 19 is pressed into bore 18. When the chuck is stopped the braking moment vanishes, air carried by duct 20 from chamber 17 into bore 18 extends piston 19 so that the shoe is pivoted, with element 15, against stop 27, Fig. 4, and air flows, Fig. 2, via ducts 22, 23 and 30 against piston 32 so that ring 9 is retracted to release tube 5.

Filed: 1965-01-18
Abstract: 1,125,711. Electronic counters. MASCHINENFABRIK AUGSBURG - NœRNBURG, A.G. 27 Sept., 1965 [26 Sept., 1964], No. 41077/65. Heading G4A. A reversible ring counter comprises in each stage a thyristor such as 310 which, when conducting, biases the adjacent thyristors 201, 401 through RC-diode circuits so as to respond to a negative impulse applied over a reverse or a forward counting lead, 11 or 12 respectively. As the adjacent thyristor becomes conducting so a pulse through capacitor 311 or 411 cuts off 301. The anode of each thyristor is connected to the corresponding cathode of a digitron (Fig. 2, not shown). Resetting is effected by momentary reversal of key 20. Two or more counters with radices having no common factor may be arranged, Fig. 3, to feed AND gates such as 50-61 so as to count up to the product of the counters.

Abstract: 938,561. Clutch control. AUTOMOTIVE PRODUCTS CO. Ltd. Dec. 21, 1959 [Dec. 30, 1958; Nov. 27, 1959], Nos. 42073/58 and 40475/59. Class 80 (2). [Also in Group XXIX] Servomotor.-A spring-engaged motor vehicle friction clutch 17, Fig. 1, is controlled in response to engine speed by a diaphragm servomotor 34 through linkage, one servomotor chamber 36 being permanently open to atmosphere and the other chamber 37 being either connected to a vacuum reservoir 39 by a regulator valve 43, the reservoir being open to the engine inlet manifold 13, or to atmosphere as determined by the position of a double closure valve 56 actuated by a centrifugal governor 57 through a diaphragm 51<SP>1</SP>; one side of the diaphragm 51 is permanently open to the reservoir 39 and the other side is connected to the servomotor chamber 37, one closure of valve 51 controlling an orifice 54 through the diaphragm 51, and the other closure controlling an outlet 55 leading to the atmosphere. During clutch engagement an increasing pressure difference on the diaphragm 51 opposes the thrust of the governor 57 so obtaining progressive clutch engagement during increase of engine speed over a small range and providing a fluidpressure " follow-up "; beyond this range the fluid acts on the whole diaphragm area to oppose the governor. In various modifications the regulator valve is dispensed with, and the servomotor is spring- loaded having one of its two chambers permanently connected to the reservoir instead of atmosphere. The vacuum reservoir may be replaced by a compressed air tank supplied by an engine-driven compressor whilst an enginedriven electric generator actuating the valve diaphragm via a solenoid in the generator circuit may be used instead of the centrifugal governor. Speed-responsive valve.-The governor weights 61, Fig. 5, which are in a chamber 112 act upon a stem 64, the chamber 112 being in a body 113 having a flange 114 and a cover 115 between which is clamped the diaphragm 51 The conduits 44, 46, Fig. 1, lead into the body 113, Fig. 5, and cover 115 by connections 116, 117, respectively, whilst the centre of the cover 115 is apertured 55 and open to atmosphere via a cap 118.

Abstract: 1,157.833. Desiccant compositions. W. R. GRACE & CO. 21 Sept., 1966 [20 Oct., 1965], No. 42201/66. Heading B1L. SiO 2  gel desiccant compositions contain 2-10% by weight of asbestos based on the SiO 2 . They may be made from a dispersion of the required proportion of asbestos in a SiO 2  hydrosol containing 5-20% by weight of SiO 2  by permitting it to gel before being washed, dried and activated. The dispersion may be obtained by dispersing asbestos fibres in an alkali metal silicate solution whose pH is then reduced to below 5 by addition of mineral acid at a temperature of 15.5-65.5C. Washing is preferably with a dilute mineral acid or acid salt whose pH is below 4.0 and temperature below 77C. Drying is at 110- 150C to reduce the water content to below 10% and activation at 200-250C to reduce the water content to 5-7%. The preferred asbestos is crocidolite though amosite may also be used. 'In an alternative method of producing the gels, sols having 3-12% by weight of SiO 2  and of pH 9.5-10.4 and containing the required proportion of asbestos are obtained either by the addition of asbestos to the preformed SiO 2  sol or by the addition of mineral acid to the preformed asbestos dispersion in an alkali metal silicate, further acid being added after gelling, preferably at a temperature .below 75C.
