Abstract: 1,213,293. Water soluble graft polymers. COURTAULDS Ltd. 5 April, 1968 [5 April, 1967], No. 15627/67. Heading C3R. [Also in Division D1] A curable, water-soluble graft polymer suitable as an antistatic agent or adhesive for application to a fibrous substrate, comprises a random polyamide carrying a plurality of N- substituted hydroxyl-terminated polyethylene oxide groups and methylol groups, which are N-substituents of the copolyamide or O-substituents of the terminal hydroxyl groups of the polyethylene oxide groups; the parent copolyamide used is one soluble in aqueous methanol containing 50% by volume of water. The methylol groups may be introduced by reacting the parent copolyamide with formaldehyde, the copolymers produced being capable of crosslinking through the methylol groups, usually in the presence of a catalyst, e.g. an inorganic acid or a salt which decomposes to give an acid at the curing temperature. Suitable parent copolyamides are binary or tertiary polymers derived from hexamethylene adipamide, hexamethylene sebacamide and caproamide.

Title: Improvements in or relating to the production of polyaryl methane dyes of the rosaniline type
IPC: C09B11/18
Filed: 1949-06-13
Abstract: Rosaniline type dyes are made by oxidizing a dispersion of a leuco polyamino polyarylmethane in an excess of arylamine by gaseous oxygen in presence of a vanadium catalyst.  A diamino diarylmethane may be employed, either as such or in the form of a reaction mixture of anhydroformaldehydeaniline with aniline and an agent effecting condensation of aniline with formaldehyde, the aniline being present in excess.  The catalyst may be ammonium metavanadate or the reaction product of sodium metavanadate with acetic anhydride.  The conditions are preferably anhydrous. Examples describe: (1) the reaction of auhydroformaldehydaniline with excess aniline in presence of hydrochloric acid, and aeration of the product in presence of each of the catalysts specified above; (2) the aeration of a dehydrated mixture of leuco parafuchsine and aniline with hydrogen chloride in presence of the reaction product of sodium metavanadate and acetic anhydride.

IPC: D06M15/423
Filed: 1956-05-24
Abstract: Regenerated cellulose textiles are impregnated with an aqueous solution of a resin precondensate in the presence of a water-soluble ketone, and are dried and baked to insolubilize the resin.  The resin precondensate may be obtained from formaldehyde and melamine, urea, acrolein or urea and acrolein.

Abstract: 333,948. Reucke, H., and Preibisch, A., (trading as Rudolphkr³ger, Telegraphen- Bauanstalt). Feb. 26, 1929, [Convention date]. No Patent granted (Sealing fee not paid). Desk and table sets; hand-combination sets; supporting ; earpieces and attachments; mouthpieces and attachments.-Relates to a telephone set comprising a microtelephone, a mouthpiece coupling ring and an earpiece coupling box, all mounted on a base plate, an auxiliary preferably enlarged mouthpiece being mounted on the coupling ring and the earpiece coupling box being equipped with one or more -sound tubes terminating in auxiliary earpieces. According to the invention, the various mounting means are adjustable on the base plate so that the apparatus can be adapted to microtelephones of different sizes and shapes. In the form shown, the microtelephone H is carried by holders l, m on the base plate a, the holder m being adjustable by means of a screw n and slot o. The mouthpiece M of the microtelephone communicates through an aperture in a holder v with an enlarged mouthpiece S adapted to be rotated both horizontally and vertically. A resilient ring ensures a sound-proof joint between the edge of the mouthpiece and the holder v, the foot t of which is provided with a projection u engaging a slot in the base plate, this slot being formed with lateral extensions w, x. A closed sound-box e carried by a support p bears against the earpiece N of the microtelephone, a resilient ring being interposed between the earpiece and sound-box. One or more tubes f extend from the sound-box to additional earpieces g which may be supported when not in use on a standard y. The base q of the support p is adjustable in two different directions on the base plate a by means of a screw engaging in slots r, s.

Title: Improvements in and relating to change speed gears
IPC: F16H29/16
Filed: 1934-05-31
Abstract: 432,460. Variable-speed ratchet gearing. VINCENZONI, A., 30, Via le del Vignola, Rome. May 31, 1934, No. 16227. Convention date, June 3, 1933. [Classes 80 (ii) and 80 (iii)] A shaft 7, carrying a toothed ratchet-disc 8, is adjusted from one eccentric position 8A, through the concentric position, to the opposite eccentric position 8B, relatively to a rotating flange 10, to provide respectively, speed increase, direct-drive and speed reduction, power being transmitted from the flange 10 to the ratchet-disc 8 (or vice versa) by means of pawls 12, pivoted on the former, and controlled by a non-rotary cam 16 which, in the eccentric positions, holds off the pawls on one side, whilst allowing them all to engage in the concentric direct-drive position. The cam 16 comprises two arcuate members, carried on pivots 46, supported by the bearing of the shaft 7, and overlapping at their free ends. A spring urges the cam-members outwardly to a limited extent, so as to mask the periphery of the ratchet-disc 8 over all but the arc between the pivots 46, means, not shown, being provided to press the cam-members inwardly in the concentric direct-drive position, so as to expose the entire periphery of the ratchet-disc. The pawls 12 have hook-shaped ends, or carry transverse pins, so as to transmit drive to the disc 8, or a pair of such discs by a push or pull. The Specification as open to inspection under Sect. 91 describes and shows a yoke for moving the cam members 16 inwardly in the concentric direct-drive position and describes two forms of friction pawls. In Fig. 5 (Cancelled), rollers 29, carried by the transmission links 27, are adapted to be wedged in one direction, between wedging surfaces 27<1> on the ends of the links 27, and a smooth groove in the driven disc 26. The above-described cam 16 acts on overhanging parts 30 of the links to lift the rollers out of engagement during their required idle travel. Fig. 6 (Cancelled) uses lozenge-shaped pawls 35, pivoted to the links 32, and adapted to wedge at each side in annular grooves 31 in the driven member. The disengaging cam 16, above referred to, acts on crescent-shaped parts 37 to tilt the pawls 35 out of the wedging position. The links 32 in another construction are replaced by pivot-blocks sliding in arcuate grooves in the face of the driving member. This subject-matter does not appear in the Specification as accepted.
