Abstract: 956,649. Bobbins. H. GLASTRA. July 10, 1962 [July 13, 1961], No. 26557/62. Heading B8M. [Also in Division D1] A composite spinning and let-off spindle comprises two coaxial cylinders 3, 4 of equal diameter and length on a driven blade 1, the upper one being drivably mounted and the other rotatably mounted. A former, split in two longitudinally and kept together by elastic bands or sticky tape, is placed on the upper cylinder, and as the blade is driven by a whorl 2, a package is built on it by a ring-andtraveller. The former and package are then pushed off the upper cylinder on to the lower one, from which yarn is drawn for re-winding while another package is built on the upper cylinder.

Title: Thermally sensitive coupling compounds and compositions containing same
IPC: C07C65/11
Filed: 1964-06-26
Abstract: Azo compounds are produced by heating to a decarboxylating temperature a normally stable acidic composition having in intimate contact as a starting material a diazonium compound and an aromatic coupler precursor therefor which contains a carboxylic acid group subject to decarboxylation when heated, said precessor being normally stable in intimate contact with said diazonium compound in said composition, said precursor being subject when heated in the presence of said diazonium compound to decompose and form a transitory material which simultaneously couples with said diazonium compound at the site of decarboxylation.  The precursor is particularly a benzoic acid which may be substituted by two or three substituents which are -NO2, -Cl, -Br, -O-CO-C6H3(NO2)2 or -O-COCX3, in which X is halogen, trinitrobenzoic acid and 3,5-dichloro or bromo phloroglucinol carboxylic acid being preferred.ALSO:The following benzoic acid derivatives are prepared:  2,4,6 - tris - 31,51 - dinitrobenzoyloxybenzoic acid, 2,6-di-31,51-dinitrobenzoyloxybenzoic acid, 2,4,6,-tris-trichloroacetoxybenzoic acid, 2,6 - ditrichloroacetoxybenzoic acid, 2,6-di - tri - fluoro - acetoxybenzoic acid, 3,5 - di-bromo - phloroglucinol - carboxylic acid, 3,5-di-chloro-phloroglucinol carboxylic acid, X-acetoxy - y,6 - dihydroxy - 3,5 - dibromo - benzoic acid, x and y are distributed between the 2 and 4 positions, 3,5-dibromo-4-benzoyl-oxy-2,6-dihydroxybenzoic acid, 2,4,6,31,51-penta-hydroxy-3 - carboxy - diphenyl, 5,21,41,61 - tetrabromo - 2,4,6,31,51 - pentahydroxy - 3 - carboxy - diphenyl, 3,5 - dibromo - gamma - resorcylic acid.

Title: Automatic stroke-changing apparatus for windmills
IPC: F03D11/02
Filed: 1952-10-23
Abstract: 743,993. Rack-and-pinion gearing. CROFTON, W. B. Oct. 23, 1952 [Oct. 25, 1951], No. 26654/52. Class 80 (1) [Also in Groups XXVI and XXVIII] A device whereby the stroke of a windmill-driven pump is automatically halved in order to reduce the load when the wind velocity falls comprises a pair of racks 1, 2 slidable in fixed channels 3, 4, the rack 1 being reciprocated at constant amplitude by the windmill while the rack 2 is free. An interposed pinion 5 is carried by the pump rod 9, and a U-shaped latch 12 is pivoted on the pinion shaft and controlled by a speed-responsive mechanism to couple and uncouple the pump rod 9 and the rack 1 by engagement with a recess 13 in the rack head so that at normal high speeds the two racks and pump rod move bodily together to transmit a full stroke while at low speeds the rack 1 rolls the pinion 5 up and down the stationary rack 2 so that the pump rod stroke is half that of the rack 1. The speed-responsive mechanism comprises a member 25 pivoted at 26 to the head of the rack 1 and having a projection 29 which at each descent of the rack 1 is knocked by a fixed abutment 28 so that the member 25 is swung through an are proportional to the speed of the windmill. The latch 12 is normally held upright against a stop by a spring 18 attached to a pivoted arm 16 whose end supports an arm 14 on the latch so that normally the latch enters and remains in the recess 13 and a full stroke is transmitted. An arm 20 pivoted to the channel 3 is urged outwardly by a spring 21 against a fixed plate to form a throat 23. At normal (high) speeds the member 25 is swung clear of the throat, but if the rack 1 is lowered slowly the member 25 enters the throat and displaces the arm 20 so that an abutment 20" thereon is moved into the path of the end of the descending arm 16. As the arm 16 strikes the abutment it is rocked against its spring 18 and the latch 12 is disengaged from the recess 13 by a weighted lever 27, whereupon the rack 2 remains stationary in its lowermost position and a half stroke is transmitted. As the arm 20 is displaced it additionally acts through a buffer spring 21a to move a slide 30 to the position shown below the end of the rack 2 to relieve the load on the latch and allow it to disengage freely from the recess 13. During half-stroke operation the load of the rack 2 retains the slide 30 in the position shown against the action of a spring 21b which, during normal full stroke operation, holds the slide in an inoperative position to the right of that shown.

Abstract: 444,324. Friction clutches; variablespeed gearing. BACKER, J. DE, 1221, Chaussee d'Alsemberg, Uccle, Brussels. Sept. 18, 1934, No. 26842. Convention date, May 11. [Class 80 (ii)] A multiple clutch for successively driving a number of concentric shafts, such as the shafts 1, 19 and 33 of the variable-speed gear described in Specification 309,563, [Class 80 (ii)], comprises a number of individual clutches, each comprising a drum 8 in which are disposed a driven clutch plate 2, splined on one of the concentric shafts, and a pressure plate 5 to which are secured longitudinallyextending rods 13 which at one end are subjected to the action of springs 16 tending to engage the clutch. The drums of the various clutches are secured to each other and the left-hand drum is secured to a driving flywheel 11, while the springs 16 of all the clutches abut against the left-hand drum. Radial disengaging levers 17 pivoted on the cover plate 12 of the right-hand drum and cooperating with adjustable abutments k on the rods 13 are actuated through rocker levers 21 by the inclined ends of longitudinal ribs 28 on a spring-loaded sleeve 24 which is slidable within the hub 25 of the plate 12 under the control of a fork 32, the ribs 28 projecting through slots in the hub 25 so as to prevent relative rotation of the sleeve 24. The ribs 28 associated with the different clutches are of different lengths, as shown in Fig. 5, the arrangement being such that as the sleeve 24 is moved to the right the clutches are disengaged in succession, while as soon as one clutch has been disengaged its associated rocker levers engage the outer flat face of the associated ribs 28 so as to relieve the sleeve 24 from the effect of the springs of that clutch. Similarly, as the sleeve is allowed to move to the left, the clutches engage in succession. The disposition of the levers and ribs may be such that the engaging and disengaging movements of the sleeve are reversed.
