Abstract: 758,360. Endless belt conveyers; manifold devices for lifting bottles. BERRY, R. M. Oct. 11, 1954 [July 13, 1953], No. 19310/53. Classes 78 (1) and 78 (4). [Also in Group XVII] Bottles are fed by a conveyer (not shown) disposed at right angles to the conveyer frame 11. Mounted in the frame 11 is a running conveyer belt 12. Bottles are fed across the belt 12 at right angles to its direction of motion between a guide rail 13 and a gate 15 which is raised automatically on the filling of a row of bottles across the belt 12. When the gate 15 on pivoted arms 16 rises a stop 25 is lowered to stop the flow of bottles on to the belt 12. The bottles travel between guide rails 27 on to a frame 28 where, on completion of loading of the frame, their necks are gripped by grippers 34 which then lower them into a crate below the frame. The grippers 34 are actuated by plungers 38 when the foremost row of bottles on the frame 28 depresses plungers 42. Supporting bars 31 slide from under the bottles which are deposited in a crate below the frame 28, the grippers then being automatically released and the frame returning to its original position.

Abstract: 239,344. Hollingworth, E. Aug. 15, 1924. Change-box motions.-In a loom for weaving chenille Axminster carpets, blankets, &c. having plain parts and parts comprising chenille weft, and in which there are two or more shifting shuttle boxes at each end of the lay, the top shuttle boxes are brought into line with the raceway, the shuttle-box operating Levers are held out of action, the rate of take-up is increased, and the starting handle is prevented from " locking " in the starting position so that the loom is stopped after every pick, while chenille weft is being woven in. The shuttle boxes are connected by flexible chains &c. 7 to levers 6 controlled by springs 9 and cams 5, the boxes being lowered when the cams actuate the levers 6. The levers 6 are connected by links 13 to the ends of levers 10 pivoted at 11, the opposite ends of the levers being normally free to move in vertical slots in a grate 14 connected by a link 16 and crank 18 to a hand wheel 21. When the grate 14 is lifted, the levers 6 are moved away from the cams 5, and consequently the shuttle boxes are lowered.
Patent GB-833666-A (GB)
Title: Aldehyde condensation reactions
IPC: C07C49/17
Filed: 1956-06-22
Abstract: Aldol-type condensation products are prepared by the method claimed in the parent Specification in the presence of a volatile tertiary amine as sole catalyst, the condensation being effected under a pressure above atmospheric and the reaction mixture containing more than 19% by weight of water.  This procedure allows of the use of higher temperatures, e.g. 80-90 DEG  C. Preferably, the reactants, amine catalyst and water are passed through a reactor in which the pressure is superatmospheric and then passed to the top of a distillation column; unchanged reactants, water and amine catalyst are removed overhead and returned to the reactor and the aldol-type products are removed as bottoms.  The procedures and apparatus described in the parent Specification may be utilized, the reactor being provided with a valve on its outlet whereby the reactor may be operated at elevated pressure and the distillation effected at ordinary pressure.  The aldol-type condensations, classes of reactants and amine catalysts are as described in the parent Specification and the products may be catalytically dehydrated by the methods and in the apparatus described therein.  Examples describe the auto-condensations of acetaldehyde and butyraldehyde and the condensations of acetone and methyl ethyl ketone with formaldehyde, the reactions being operated continuously in the presence of 19.4% upwards of water and trimethylamine or triethylamine as catalyst, the reactor temperatures ranging from about 55 DEG  to 86 DEG  C. and the pressures from 20 to 60 p.s.i.g.; the aldoltype condensation products are subsequently dehydrated to yield corresponding unsaturated aldehydes or ketones by heating with aqueous phosphoric acid.

Title: Improvements relating to carburetters for internal combustion engines
IPC: F02D11/02
Filed: 1939-07-04
Abstract: 530,810. Fluid-pressure servomotors. AVIMO, Ltd., and LAURET, M. A. July 4, 1939, No. 19413. [Class 135] [Also in Group XXVII] A control mechanism for the throttle valve of a carburetter, which can be actuated either by the pilot or by a hydraulic mechanism controlled by a capsule responsive to induction-pipe or atmospheric pressure, as described in Specification 498,974, [Group XXVII], comprises a lever a operable by the pilot, a lever g for imparting movement to the throttle valve, a coupling f interconnecting and slidable relatively to both levers, and a hydraulic piston responsive to the action of the capsule and connected by a link h to the coupling. When the throttle valve is closed, the levers a, g are substantially in alignment, so that movement of the coupling f by the piston j has no material effect on the throttle valve. The lever a is then in contact with a stop p. As shown, the lever a is secured to a spindle b having an arm operable by the pilot, and the lever g is a bell-crank, the arm g<SP>1</SP> of which is connected through a link m and lever mechanism to the throttle valve. The coupling member f carries freely mounted rectangular collars o slidably engaging slots e, n in the levers a, g.

Title: Improvements in devices for driving machines for example alternators, at substantially constant speed from a variable-speed shaft
IPC: H02K7/10
Filed: 1958-06-18
Abstract: 861,532. Toothed gearing. PRECISION MECANIQUE LABINAL. June 18, 1958 [Dec. 16, 1957], No. 19456/58. Class 80 (1). [Also in Group XXXV] An alternator shaft 2 is driven at constant speed (see Group XXXV) from a variable-speed drive shaft 1 connected to the planet-carrier 12 of a spur differential, one of whose sun-wheels 18 drives shaft 2 and the other 17 is controllably braked by an eddy current brake 5 whose rotor is mounted on the same hollow shaft 36. Planet gears 13, 16 engage sun-wheels 17, 18, while gears 14, 15 (which are shown spaced in Fig. 2) actually engage each other. Since these planet gears are all on the same side of the carrier 12, a pair of balance weights 19 are provided on the opposite side. The planet gears are forcefitted on to a polygonal sleeve 21 which rotates on needle rollers 34 on axles 31 mounted in the carrier 12. Lubrication difficulties are experienced because the gears 13, 17 must necessarily be located outside the carrier 12. This difficulty is overcome by providing three separate channels 25, 26, 27 in which lubricant for the various gears is retained so that little escapes through the aperture 23 through which the gear 13 projects. In addition a deflector 28 causes escaping oil to be returned centrifugally through apertures 29, 30 in the balance weights 19 and 32, 33 in the axles 31. In addition, a returning thread 35 is provided on the periphery of the carrier 12.

Title: Improvements in valve gear for hydraulic control transmission pipe lines
IPC: B66F3/24
Filed: 1943-11-22
Abstract: 576,033. Hydraulic transmission of power. ARNOLD, H. I., and EXACTOR CONTROL CO., Ltd. Nov. 22, 1943, No. 19518. [Class 69 (ii)] In a remote control system comprising a. transmitter A and receiver B, a valve device C, inserted in the conduit 10 between them, comprises a non-return valve 22 and a relief valve 28 mounted on a diaphragm 30 sensitive to pressure changes in the conduit between the transmitter and the device. The spring 33 acting on the diaphragm and transmitter spring 8 are such that changes in pressure between the device and transmitter due to leakage or temperature variations affect only the transmitter. While pressure can be transmitted to the receiver through the non-return valve, reverse loads due to pressure on the receiver merely close the valves ; but return of the transmitter to original position causes a drop in pressure on the conduit 10 which acts on the diaphragm and causes the relief valve to open. The relief valve may be manually actuated. In a modification one valve serves both as non-return and relief valve. The device is preferably located near the receiver.

Title: Improvements in a filling fork and stop motion for an oriental rug loom
IPC: D03D39/02
Filed: 1928-07-06
Abstract: 320,328. Marks, E. C. R., (Whittall As. sociates, M. J.). July 6, 1928. Weft tension, regulating apart from shuttles in shuttle looms.-In an orieutal rug loom, stopmotion weft forks 26, 22 at each end of the loom are raised and lowered in slots in the lay by plates 25 and lever mechanism 30, 31 connected to a shaft 32, which is rocked by means of an arm 38 resting on a lever 39, actuated by lugs 44 on a cam 42. After a row of pile tufts has been inserted whilst the lay is stationary, the weft forks are raised whilst a shuttle is picked from the left hand box to the right hand box, then the weft forks fall on the weft and clamp and tension it whilst it is beaten up. The procedure is repeated whilst a second weft is inserted and beaten up. As the lay moves back and is about to come to rest for the insertion of a row of tufts, the forks are raised slightly to free the weft and provide slack to prevent the pulling away of the weft from the fell of the fabric. The forks fall again on the weft before the lay has reached its rear position, thus preventing any more weft from being pulled out of the shuttle by the knotting in of the tufts, which might cause an uneven edge.

Title: Improvements in apparatus for testing the accuracy of gear teeth
IPC: G01B5/20
Filed: 1931-07-09
Abstract: 376,496. Surface and outline gauges. BROWN & SONS (HUDDERSFIELD), Ltd., D. and GOULDER, J., Park Gear Works, Lockwood, Huddersfield. July 9, 1931, No. 19719. [Class 106 (ii).] For checking the profile accuracy of involute gear teeth, the base disc b to which is secured the gear a to be tested is adapted to be rolled between a fixed straight edge d' and a rod or bar h by axial movement of the latter, a gauging member r<1> being arranged to bear against the tooth profile and an indicator being provided to indicate irregularities of profile. The straight edge d' is formed by a bar d secured to a bedplate c. Also mounted on the plate c is a carriage e which can be clamped to the bed at any point of its travel. Passing through the carriage are two parallel spindles f, f<1> carrying rollers g, g<1> which are disposed at exactly equal distances from the straight edge. The spindles are arranged so that the bar h can be passed between the rollers and the base disc b in contact with both. The rollers are caused to engage the bar h with pressure by means of a crosshead i and nut j working on a threaded projection of the carriage. A slide m mounted on balls to move parallel to the straight edge and normally held in the central position by springs carries a pillar p on which is adjustably clamped the gauge member r. An abutment s on the slide engages the plunger l<1> of a dial indicator t clamped to the base. The end of the member r is provided with a part r<1> having a flat outer face and conical inner face forming a circular knife-edge which is arranged to be in the plane of the straight edge. The gear is adjusted by hand so that the edge r<1> engages the face of the involute with sufficient pressure to cause the pointer to occupy a central or zero position. The gear is then rotated by moving the rod h axially and if the curve of the tooth is a true involute the pointer should remain stationary.
