[Class 112.] In a method of knitting fashioned stocking blanks which involves running on previously worked heel portions, a part worked stocking blank is run on, at the point where the high splice 3 adjoins the sole portions 4, to two closely superposed rows of needles 5, 6, 61, which may be part of a looping machine. The portions 3, 4 are then severed by passing a knife between the rows. The needles 6, 6<1>, for the sole portions 4 are mounted on devices capable of being turned through 180‹. When this is done and the needles are all in one plane, the edges 11 of the heel portions 2 can be run on to the groups 6, 6<1>, while the initial courses 12 are run on to the groups 5. The doubled portions are linked together as usual. In another method, a completed blank after removal from the knitting-machine is run on to the groups 5, 6, 6<1> of the linking machine on a line slightly beyond the joining edges 12 whereupon the parts 3 and 4 are severed and the parts 4 folded over in line with the parts 3. The edges 11 are then sot on the needles carrying the parts 4 and the linking completed.

Title: Improvements in or relating to brakes
IPC: F16D65/46
Filed: 1941-10-02
Abstract: 554,071. Brakes. BENDIX AVIATION CORPORATION. Oct. 2, 1941, No. 12748. Convention date, March 22. [Class 103 (i)] In an internal drum brake comprising a pair of shoes each anchoring at one end or the other occording to the direction of rotation of the drum, operation is effected by a pair of levers pivoted on one shoe and connected by struts and auxiliary levers to the other shoe and means for simultaneously adjusting the shoes and the operating mechanism are provided. The brake shown is normally applied by hydraulic cylinders 12, 12a, each shoe anchoring at one end or the other on the adjacent cylinder according to the direction of drum rotation. The mechanical operating means comprises a pair of levers 22, 23a, pivoted at 23, 23a to the shoe 13. Levers 35, 35a, mounted respectively on the shoe 13a and the lever 22a engage with one arm, struts 20, 20a the other ends of which engage respectively the lever 22 and the shoe 13a. The other arm of each lever 35, 35a bears upon the en of a rod 41 that screws into a tubular member 4 which in turn screws into the corresponding cylinder cap 43. The internal and external screw-threads of the member 40 are of opposite hand. The member 41 is slotted to receive the web of the corresponding shoe and a T-piece 42 which bears on the head of the member 40 and also on the shoe end. When the brake is operated hydraulically the pistons move the shoes through the caps 43 and the members 40, 42. The levers 22, 22a are operated by an equalizer 28a pivoted on the cranked end 25a of a shaft 25 mounted in the anchor plate 11 and carrying an outer arm 26 to which a cable is connected. Operation of the levers 22, 22a moves the shoe 13a through the struts and the levers 35, 35a which fulcrum on the rods 41, the shoes anchoring at either end accordto the direction of drum rotation. Adjustment of the shoes is effected by turning the members 40 and the rods 41 since they are held from rotation by the shoe ends move outwards relatively to the members 40 and thus similtaneously turn the levers 35, 35a and thus take up the slack in the mechanical operating mechanism. According to the Specification as open to inspection under Sect. 91, means external to the brake are provided for taking up the slack in the mechanical mechanism, the levers 35, 35a may be dispensed with, the struts then engaging directly the shoe 13a and the corresponding lever 22, 22a. In a further modifica tion a single strut and lever acting only on one pair of adjacent ends of the shoes is provided. In this case the shoes anchor at the other pair of adjacent ends during mechanical operation so that only one shoe is self-energising. This subject-matter does not appear in the Specification as accepted.

Abstract: 864,052. Controlled non-linear inductors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 21, 1959 [April 22, 1958], No. 12770/58. Class 40 (9). An arrangement for switching an alternating current comprises a coil on a toroidal core which is saturated when a permanent magnet is brought into proximity with a diameter of the core. As shown in Fig. 2, a core 1 of H.C.R. alloy has soft iron polepieces 4, 5 which align with polepieces 6, 7 of a permanent magnet 3, the magnet being movable between a soft iron keeper plate 8 and the core so as to provide " off " and " on " conditions for current in a coil 2. In a modification, Fig. 3, the magnet 3 is secured to a spindle 11 which passes through a non-magnetic back plate 12 and a fixed keeper plate 15. The outer ends of the spindle are terminated by a stop 13 and a push-button 14, and springs 16, 17 are located each side of the keeper plate to provide a snap action. In operation the magnet is held by its attractive force to either the keeper plate or the polepieces, one of the springs being compressed. By depressing or pulling the button 14, as the case may be, the attractive force of the magnet is reduced and the compressed spring provides a snap action movement to the other switch position. On application to a limit switch is described, Fig. 4, in which relative movement takes place between a movable magnet and a fixed core, no keeper plate being provided. An alternative arrangement is shown in Fig. 5 in which the core 1 and permanent magnet 3 are both fixed and the switching action is controlled by movement of a keeper plate in the air gap between the two fixed members.

Filed: 1961-04-10
Abstract: 959,800. Rolling. UNITED STATES STEEL CORPORATION. April 10, 1961 [April 28, 1960], No. 12867/61. Heading B3M. [Also in Division G3] A method of rolling strip comprises passing a strip under tension between two pairs of rolls in sequence, measuring the thickness of the strip after the second pair of rolls at a plurality of positions transversely of the strip, and transversely varying the longitudinal tension of the strip in accordance with variations in the strip thickness. The tension of the strip S after passing rolls 2 is controlled by rollers 5 which rotate in the plane of the rollers, the thickness of the strip being measured by gauges 14, 16 and 18 arranged transversely of the strip. Signals from these gauges are fed into differential amplifiers 20, 22, the outputs of which control the direction of rotation of motors 34, 40 running from D.C. supplies at 32 and 36., Rollers 5 in a frame 48 are tilted by threaded spindles 345, 405 of the motors. If the strip is thicker at one edge than at the centre, a signal causes the rollers to be lifted at that edge to increase the tension and hence give a greater reduction to the edge in the rolls 4. A similar arrangement is described where the outputs of two bridges, including strain gauges mounted in the frame of rolls 4, are fed to the differential amplifiers.

Title: Treatment of fibre-forming polyolefines
Inventor: O'NEILL WILLIAM ALEXANDER
IPC: C08L23/02
Filed: 1962-04-04
Abstract: The melt-spinning properties of mixtures comprising polyolefines and incompatible polymeric substances are improved by inactivating the residues of polymerization catalysts in the polyolefine by heating, advantageously from 250 DEG  to 300 DEG  C., the polyolefine with a substance which reacts with said catalyst residues to form a compound which is soluble or dispersible in the molten polymer and is incapable of reaction with the incompatible polymer.  The inactivating substance may be a compound A-X-H, where X is an oxygen or sulphur atom and A is R- or <FORM:0987012/C3/1> where R is alkyl, aryl or alkaryl, such compounds being soluble or fusible in the molten polymer, having a boiling point in excess of 300 DEG  C. and preferably being monofunctional. Certain substances which are not fusible may also be used, for example inorganic compounds containing hydroxyl groups, such as disodium hydrogen phosphate and hydrated metal oxides, provided they are sufficiently finely dispersed in the molten mixture.  Hydrated metal oxides in which the metal is polyvalent may be used advantageously as the partial salt of a monobasic aliphatic acid containing more than 6 carbon atoms.  The polyolefine is preferably treated with the inactivating substance before the addition of the incompatible polymeric substance. However, the inactivation may be carried out by using the incompatible polymer as the inactivating substance.  In this case the polyolefine/incompatible polymer mixture is heated until formation of the ceramic-like complex is complete, prior to passing the molten mixture through the narrow passages of a spinning unit.  The incompatible polymer may be selected from polyesters, copolyesters and polyamides.  In the example, isotactic polypropylene containing titanium alkoxide as catalyst residues is heated with basic aluminium stearate at 270 DEG  C., cooled, chipped and then mixed with polyethylene terephthalate and melt spun.  Specification 968,335 is referred to.
