Title: Improvements in and relating to polyacrylonitrile solutions
Inventor: BROOK BASIL WILLIAM
IPC: C08F20/44
Filed: 1956-04-10
Abstract: Acrylonitrile, either alone or in admixture with up to 20 per cent of one or more other ethylenically unsaturated compounds such as methyl acrylate, styrene or vinyl acetate, is polymerized in an alkaline concentrated aqueous solution of an inorganic thiocyanate, e.g. sodium thiocyanate, in the presence of a hydroperoxide catalyst, e.g. cumene, tetrahydronaphthalene or tertiary butyl hydroperoxide.  The aqueous solution, whch may contain an alcohol, may be rendered alkaline by means of an alkali such as sodium carbonate but, more preferably, by an amine such as tetraethylene pentamine or tetramethyl methylene diamine which also functions as an activator of the hydroperoxide catalyst but which may result in a discoloured solution, an effect which may be avoided by the addition of formaldehyde prior to polymerization. During the course of polymerization further quantities of monomer and catalyst may be added to the reaction system.  The resulting polymer solutions may be spun into fibres by the methods described in Specifications 672,775, 714,530, 729,472 or 732,135. Specifications 626,155 and 796,294 also are referred to.

The field structure consists of U-shaped cores and windings 42, and the armature is arranged to reciprocate between the poles 41. A.C., pulsating or mixed current may be used. The spring 31 is composed of laminations clamped at their ends in openings in a frame comprising the members 26, 27, 28, 29, which is secured to the apparatus. The armature consists of a pile of laminations slotted at their edges to take the coil windings 49 which may have two coil sides as shown, or a single side as in Fig. 6 (not shown). In order to provide greater flexibility, the spring may be formed of two sets of laminations 53, 54, Fig. 4, connected at their ends by brackets 55, 56. One set is attached to the armature and the other set is secured to the apparatus by brackets 60. By adjusting the relative strength of the springs, the brackets 55, 56 may be at points of zero amplitude, in which case they may be used as supports for the apparatus, The Specification as open to inspection under Sect. 91 describes also a modification, Fig. 8 (Cancelled), in which the armature is clamped to the centre of the springs 63 and drives the apparatus 120. The structure 36, which carries the field magnets and to which the ends of the springs are clamped, is mounted on a base structure 68 through resilient supports 67.

Abstract: 289,428. Lavaud, D. S. de. April 27, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Ratchet gearing.-In friction ratchet gearing employing wedging balls, rollers, or cam-shaped pawls, simultaneous action of the wedging- members is secured by the provision of a cage rigidly, frictionally, or resiliently connected to the oscillated driving-member, which, in order to reduce friction on the idle stroke, is mounted on ball or roller bearings running on a race other than the wedging-surface of the driven member. The driving-crown 1, Fig. 1, runs on balls 4 engaging a race 3 independent of or rigid with the driven hub 2, and has cam surfaces 5 to coact with wedging-rollers 6, which are spaced by shaped bars 8 carried by lateral rings 7 rigid withthe crown 1. In a modification, the rollers 6 are hollow and lie in contact, the bars 8 being replaced by pins passing through the rollers, and the cage is adjustable for reversing the drive. Fig. 3 shows inclined cam-parts 6a spaced by pins 10 extending from the cage-rings 11, which are so connected to the crown 1 by friction pads 12 as to allow slip. Mention is made of the effect of inertia in assisting simultaneous action of the pawls.

Abstract: 494,156. Brake-holding devices; controlling motor vehicles. PILBLAD, E. J., STRANGE, C. C., McINTOSH, A. J.,BARACH, A. LER., and BARACH, E. J. April 17, 1937, No. 11024. [Class 103 (i)] [Also in Group XXXI] A brake-holding device for vehicles comprises a pivoted locking member 33 which is actuated on full depression of the clutch pedal 19 to bind onto a rod 23 connected to the brake pedal 20 and hold the brakes in the applied position. On release of the clutch pedal, as on starting the vehicle, a catch arm 43 is actuated to move the locking member 33 to its inoperative position and so release the brakes. The locking member 33 is pivoted to a fixed bifurcated member 34 having lugs 21, 22 with openings for guiding the rod 23, and has a portion 37 with an opening 38 through which the rod 23 can normally move freely. The member 33 is urged into its inoperative position by a spring 39 but on engagement of the clutch pedal with a part 42 it is tilted as shown in Fig. 3, so that the opening 38 binds onto the rod 23 to hold the brakes in the applied position, this locking action being assisted by the tendency of the brake mechanism to disengage. The catch 43, which.is pivoted on the member 33, is meanwhile moved into the position shown in Fig. 3, so that, on release of the clutch pedal for the clutch engagement, it is actuated to move the locking member 33 to its inoperative position, by means of a cam portion 50, to release the brakes. Whilst the brakes are locked in the applied position they can be further actuated if required by additional pressure on the brake pedal since the locking device acts in one direction only. The locking device may be independently actuated apart from the clutch operation to hold the brakes applied when it is desired to leave the vehicle unattended by means of a cam lever 55 which acts against a projection 58 of the locking member 33, and which is operated by a rod 60 from a hand lever on the steering column 12.
