Abstract: 1285051 Laminates IMPERIAL CHEMICAL INDUSTRIES Ltd 13 March 1970 [27 March 1969] 16048/69 Heading B5N [Also in Division C3] Laminates are produced from fibre-reinforced synthetic resin composites comprised of a mixture of a resin which is the product of curing an isocyanate terminated prepolymer obtained by reacting a polyisocyanate with a polyol, at least one of which contains a cyclic group between two functional (i.e. OH or NCO) groups, the prepolymer having no more than 12 atoms in the chain between neighbouring cyclic groups, the cured resin having a heat distortion temperature of at least 50 C., and carbonized fibres which form 20 to 75% by weight of the composite. The composite is suitably prepared by placing a layer of long fibres in a mould, impregnating the fibres with a liquid mixture containing prepolymer, curing agent and optionally a diluent, and removing any diluent and curing the prepolymer by heating. The curing agent is suitably a catalyst which causes trimerization of isocyanate groups, a polyepoxide, azino compound, aldimine or bisaldimine of an aromatic aldehyde or a carbodiimide. The prepolymer is suitably prepared by reacting diphenylmethane diisocyanate or the crude phosgenation product of an aniline/  formaldehyde reaction product with the product of reacting 2 to 4 moles of propylene oxide with one mole of 2,2-bis-(p-hydroxyphenyl)propane. In the mould, the fibres may be laid individually or in the form of bundles, hanks, rovings, tapes, ribbons, mats or tissues. It is preferred to apply pressure to the impregnated fibres-while curing the resin. Where comparatively thick articles are required, a number of impregnated layer composites may be prepared, a stack formed from these layers and then the prepolymer cured, preferably while pressing the layers together.

Title: Improvements in and relating to circuit arrangements for effecting the exchange of energy between alternating current and direct current mains networks
IPC: H02M7/00
Filed: 1935-06-05
Abstract: 441,917. Converting. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. June 5, 1935, No. 16363. Convention date, June 7, 1934. [Class 38 (ii)] Relates to an arrangement for the interchange of power between an A.C. network 1 and a D.C. network 2 and consists in interconnecting the networks by means of one or more discharge devices 3 having reversing switches to permit of rectifier or inverter operation and by means of one or more groups of discharge devices 7, 8 connected oppositely to permit of rectifier or inverter operation without the need of reversing switches. The group 7, 8 in cross connection is designed only to take a small percentage of the total load and is arranged to take all the load during transfer from rectifier to inverter operation and vice versa of the discharge devices 3. If desired relays in the D.C. leads of the group 7, 8 responsive to direction of current flow, may be used to effect operation of the reversing switches. Alternatively the relays may be inserted in the cross connections of the group 7, 8, in this case the relays need only be responsive to current flow. Where certain of the discharge devices are switched out when the load has fallen below a certain value (e.g. 50 per cent) the reversing switches of these devices may be changed over immediately, so that they will be ready for operation when change-over occurs.
