Title: Improvements in or relating to Stop-motions for Machines for Winding Yarns.
Inventor: BAYLEY WILLIAM HENRY
IPC: B65H63/036
Filed: 1917-03-28
Abstract: 114,318. Bayley, W. H. March 28, 1917. Stop-motions.-In a machine for winding artificial silk or other yarn from the hank on to bobbins or cops, &c. on vertical, oblique, or horizontal axes, the bobbin &c. is separated from its driver on the tension becoming excessive. The yarn b<1> drawn from the swift l passes over a fixed guide q and under a guide r carried by a lever t, the forked end a of which embraces the driver s of the bobbin i. Increase in the tension of the varn tilts the lever and raises the bobbin from its driver. The end t<1> of the lever is depressed and allows a weighted catch v to slip over it, and hold the lever until the hank is disentangled and ready for winding to proceed.

Title: Improvements in the refining of fatty glycerides
IPC: C11B3/06
Filed: 1951-05-25
Abstract: The alkali refining of fatty glycerides containing free fatty acids carried out continuously in the presence of a minor proportion of an aliphatic polycarboxylic acid, anhydride or salt of such acid other than tartaric acid, or a salt or anhydride thereof, and the refined oil phase and the aqueous phase containing the impurities are separated by centrifuging.  The preferred polycarboxylic acids are straight or branched chain hydrocarbons having 2 to 5 carbon atoms substituted at several or all of the carbon atoms with COOH groups: the ammonium, alkali and alkaline earth salts or the acid anhydrides may also be employed. Desirably one or more of the carbon atoms carry hydroxyl groups. Specified acids are citric, maleic, malic and oxalic acids.  The additive may be employed in amounts of less than 1 per cent. and preferably 0.02 to .2 per cent., by weight calculated as anhydrous on the weight of glyceride to be treated; 0.04 to 0.1 per cent. gives the best results.  It is preferred to use it in the form of a 5 per cent. to saturated aqueous solution.  Sodium hydroxide is the preferred refining alkali.  The polycarboxylic acid, salt or anhydride may be incorporated with either the oil or the refining alkali solution prior to mixing or it may be blended with the refining mixture during or after its formation.  It is preferred to add it to the oil prior to adding the alkali.  The refining mixture may be blended at about 16 to 24 DEG C.; if desired 1 to 2 per cent. of steam may be introduced into the mixture of unrefined oil and additive prior to adding the alkali.  In an example a non-degummed expeller soya-bean oil containing 0.55 per cent. free fatty acids is refined with caustic alkali lye in the presence of 0.06 per cent. citric acid, added as a 10 per cent. aqueous solution, 1 1/2 per cent. of steam being injected in the mixture before addition of the lye.

Title: Improvements in tube-testing presses
IPC: G01M3/28
Filed: 1954-04-30
Abstract: 752,256. Hydraulic testing of tubes. SCHLOEMANN AKT.-GES. April 30, 1954 [May 19, 1953], No. 12565/54. Class 106 (2). A testing press for testing tubes of magnetic material, e.g. steel, having a fixed test head 1 and a second head 2 displaceable in the direction of the tube axis is provided with holding members 7 of permanently magnetic material to hold the tubes in test position against buckling, the members 7 also serving to move the tubes 12 into and out of engagement with the test heads 1, 2. As shown, the members 7 are formed as rollers having on their axles gears 11 meshing with toothed segments 9 pivoted at 10 and operated by a rod 6 connected to the lever 3 by means of which the displaceable test head 2 is moved into position. The portions 7a of the rollers are non-magnetic. The tubes 12 are placed initially into position to contact the sectors 7a and head 2 is then moved axially towards the tube. This movement rotates the rollers to hold the tube and move it into engagement with the head 1. The lever ratios are such that the total displacement of the head 2 is greater than the axial movement of the tube so that the head 2 also is brought into engagement with the tube. After the test, the head 2 is moved away, the tube 12 disengages from the heads 1, 2 and at the end of the rotational movement of the rollers the sector 7a is once more in engagement with the tube so that it may be lifted free of the press. In another embodiment the holding members move linearly in the direction of the tube axis, a degree of lost motion being provided, and means are provided to insert a plate of non-magnetic material between the tube and its holding member at appropriate points in the operating cycle.

Abstract: 561,339. Knitted fabrics. KRETSER, R. Sept. 7, 1942, No. 12591. [Class 74 (ii)] A knitted fabric somewhat similar to a woven fabric in appearance is obtained by the use of wrap threads d ... k knitted by needles which do not knit the course-wise extending body yarns a, b, a<1>, b<1>. The fabric is knitted upon a multi-feeder circular machine, and at each feeder pattern wheels A, B are provided so that selected needles take and knit yarns supplied by guides spaced circumferentially of the machine, as well as a third pattern wheel C which raises the remaining needles so that they knit wrap yarns supplied by guides 60 individual to the needles. Several yarn guides may be provided in connection with each pattern wheel A, B so that horizontal colour striping may be obtained. The arrangement of yarns caused by each needle knitting only one yarn provides wale-wise floats 66 in the wrap yarns and coursewise floats 62 .. 65 in the body yarns and reduces the stretchability of the fabric in both directions.

Abstract: 917,236. Electric selective signalling systems. BENDIX CORPORATION. April 10, 1961 [April 15, 1960], No. 12845/61. Class 40 (1). A stepper-motor 15, Fig. 1, is so arranged in association with two relays 26, 32 as to make a complete rotation, either forwards or backwards, in response to a pulse on one of lines 10, 11, respectively. A first field winding 40 of the motor is normally carrying current thereby maintaining a permanent magnet rotor in the position shown, and the two relays are arranged to be slow to pick-up and also to release. In operation an input pulse first causes a horizontal field component by passing through a selected half of a centre-tapped second winding 14. This determines the direction of rotation. Thereafter one of the two relays picks-up, and when the input pulse ends it releases, and this causes the resultant field produced by the two coils to step around a complete revolution either forwards or backwards.

Title: Improvements in and relating to gas producers
IPC: C10J3/34
Filed: 1936-05-08
Abstract: 460,554. Gas producers. KOLLER, K. May 8, 1936, No. 13014. [Class 51 (ii)] Charging ; charges, agitating.-In a gas producer 1 having an agitator 8, 9, 10 eccentrically mounted in a rotary cover plate 3 so that it rotates therewith about the axis of the producer, the agitator tube 8 is given, in addition, a movement of complete rotation about its own axis and means are provided by which the agitator is automatically raised when increased resistance, due to a rise in the level of the fuel bed, is encountered and is allowed to fall under its own weight when the fuel level drops. As shown, the tube 8 is guided in a bearing 14 and is rigidly secured in a member 16 which carries racks 17 meshing with pinions 18 mounted on the inner ends of shafts 32, the outer ends of these shafts carrying bevel gears 31 in mesh with a gear rim 30 on a casing 26. The latter also carries a second gear rim 29, which by engagement with a fixed rim 7 ensures rotation of the cover 3 and the mechanism carried therebv about the axis of the producer, and a third rim 25 which, by cooperation with a worm 24 driven through gearing from the motor 19, effects rotation of the casing 26 and thus the tube 8 about the axis of the latter. When the movement of the agitator is hampered by increased resistance due to overcharging, the gears 31 roll on the rim 30 and thus rotate the pinions 18 to raise the tube 8, the reverse operation taking place, under the weight of the agitator when the fuel level falls. The cover 3 and the parts 8, 9, 10 of the agitator are cooled by a circulating water system. The motor 19 also drives a charging device which is mounted on the cover 3 and comprises a pocketed-drum feeder 45 delivering into a rotary container 56 divided into four compartments by radial partitions, this container being closed at top and bottom by discs 49, 51 which carry diametrically opposed inlet and outlet shoots 48, 52. The shaft 44 of the feeder 45 and the gear rim 61 mounted on the container 56 are both driven from a shaft which is connected to the shaft 20 of the motor 19 through an adjustable friction ratchet drive device. Below the shoot 52 is arranged a water-cooled half-conical distributer 55.
