Title: Recording medium
IPC: H01B3/00
Filed: 1962-04-17
Abstract: A multiple layer recording medium comprises a supporting base layer at least one surface of which bears optically sensible irregularities, a layer of a film-forming thermoset polymer overlying the said irregular surface to provide a surface which is substantially free of optically sensible irregularities and which may also be applied to the backs and edges of the base, and a thermoplastic polymer layer overlying the last mentioned surface, the supporting base layer being thermally stable at the softening or deformation temperature of the thermoplastic layer, and the thermoset polymer being one which does not release gas at the softening or deformation temperature of the thermoplastic layer. Optionally, there may also be present an intermediate conducting layer e.g. of a heavy metal such as Fe, Cr, Ni or Sn, an oxide thereof e.g. SnO2, Cu2O or In2O3 or a compound e.g. CuI, which may be disposed between the base and thermoset layer or between the thermoset and thermoplastic (recording) layer.  Preferred base materials are polyethylene terephthalates and solid polycarbonate resins, other materials mentioned being cellulose acetate, polyepoxides and silicones. Specified thermoset materials are phenol/aldehyde resins optionally modified with 10-40% by weight of a drying oil acid, polysiloxanes, aromatic polyesters e.g. those obtained by the interaction of phthalic anhydride with glycerine and/or pentaerythritol and hydroquinone-isophthalate resins, polyepoxides containing amine or anhydride curing agents and heat-curable unsaturated polyesters containing styrene and diethylene glycol maleate.  Specified thermoplastics for the recording layer are polystyrene and polystyrene copolymers, mixtures of organopolysiloxanes and a thermoplastic solid comprising a polyarylene ether and/or a polystyrene.  The thermoset layer may be applied as a solution in a solvent, particularly one which exerts some solvating action (and hence smoothing) on the base material.  The thermoplastic layer may be similarly applied.

Title: Improvements in or relating to apparatus including a synchronous alternating electric current motor
IPC: H02K7/04
Filed: 1938-05-23
Abstract: 516,426. Testing balance of rotary apparatus. GENERAL ELECTRIC CO., Ltd., and CAPE, A. B. May 23, 1938, No. 15322. [Class 106 (ii)] A device for testing the dynamic balance of rotary parts comprises two or more synchronous motors, the rotors of which are each adapted to rotate 'independently about the same axis as the part under test and to rotate a balance  weight or weights about that axis, their stators being independently rotatable about their rotor axis. In the form shown the part to be tested, e.g., a dynamo rotor, not shown, is mounted on  the shaft 1 on which is rigidly fixed the rotor 5 of an alternator; the stator 2 of which is fixed in space. The shaft also carries on ball bearings 8 the rotors 6, 7 of two synchronous motors, both fed from the alternator 5, 2 and having stators 11, 12 which may be rotated on the shaft through any designed angle, e.g., by gear cooperating with toothed racks 14, 15. Each rotor 6, 7 carries out-of-balance weights 9 which may be adjusted as to position or magnitude when the device is at rest. The three rotors may be of permanent magnet or electromagnetic type. but they may carry polyphase windings, in which case the stators carry permanent or electromagnets. In use, the stators 11, 12 are rocked  through angles sufficient to neutralize the outof-balance effect in the tested part, and the  displacements and magnitudes of the weights 9 give a measure of the position and magnitude of the correcting weight to be applied to that part. In an alternative arrangement, the part to be balanced may be. driven by a further  synchronous motor supplied at the same frequency as the synchronous motors 11, 12, in which case the drive from the first-named motor to the part under balance should be free from lost motion.

Title: Improvements in and relating to transformers
IPC: H01F29/02
Filed: 1928-05-25
Abstract: 291,107. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). May 27, 1927, [Convention date]. Regulating transformers; polyphase transformers. - Relates to a. method of avoiding the production of eddy currents in the cover plate and bushings of the casing of a transformer having at least one of its windings provided with a plurality of tappings for regulating, and consists in subdividing the return conductor into as many parallel-connected branches as there are multiple bushings and taking one branch through each bushing. In the arrangement shown, the tapped winding d has its tappings divided into two groups passing respectively through metal bushings g, h. The conductors e, f, either of which may act as return conductor, are divided into two branches i, k, and l, m passing through opposite bushings. The separate branches of each conductor are connected together externally of the cover a, with the result that current in the return conductor will tend to flow in the branch passing through the same bushing as the tapping in use so as to neutralize the flux produced by the current in the tapping, the other branch having comparatively high reactance due to absence of current in the tappings in the same bushing. The application of the invention to a three phase auto-transformer is also described.

Title: Improvements in or relating to the manufacture of products from cellulose and cellulose derivatives
IPC: C08L1/00
Filed: 1935-05-27
Abstract: For the purpose of giving a permanent curl, crimp, patterned or similar shape to artificial threads, horsehair, films, staple fibres, &c. made from cellulose or cellulose derivatives, the materials are impregnated with substances capable of forming synthetic resins or with the latter substances in their partly condensed or polymerized state, and then after curling, crimping or patterning the thread, film, &c., subjecting the materials to treatment, for example, a heating operation, such as will effect further condensation or polymerization, so as to set the shape. The impregnation is effected either by treating the finished artificial threads, films, &c., or by incorporating the substances in question in the spinning solution from which such materials are made.  Thus, a partly condensed phenol-formaldehyde or urea-formaldehyde resin may be added to a cellulose solution, and the artificial silk threads or films curled or shaped by passage through fluted or goffering rollers, the further condensation being effected by heating to 80--160 DEG  C., and such further condensation may take place simultaneously with the curling if the rollers are heated.  In the case of staple fibres, the necessary curl can be produced by fans which are used for the purpose of opening up the fibre mass, and the final condensation may be effected by passing the fibres through a continuous oven.
