Filed: 1924-08-26
Abstract: 236,068. English Electric Co., Ltd., and Bremner, F. D. H. Aug. 26, 1924. Master control systems; controlling travel for a fixed number of revolutions.-In a system comprising a master switch 4 which produces circuit conditions cancelled by the movement of a secondary switch 18 driven by an electric or pneumatic auxiliary motor, a relay 3 is adapted upon failure of voltage to short-circuit its coil by way of segments 8 cn the switch 4, so that it cannot be reenergized until the switch 4 is moved to its off position. Normally the relay 3 is energized from conductor 6 through resistance 12 to earth, thereby moving its armature 1 on to contact 13 and completing a circuit, when the switch 4 is moved to its first position, through reversing switch 10, auxiliary contacts on a reverser 11, line-breaker coils 5, and segment 17 of switch 18, to earth. Closing of the line-breaker causes auxiliary contacts 16 to complete an alternative earth connection for coils 5 so that switch 18 can then be moved from its initial position. Failure of voltage allows the armature 1 to drop on to contact 14 completing the short circuit for the coil 3, and also breaking the circuit for the coils 5, with consequent opening of the line-breaker. Where the control circuit and the main motor circuit are not derived from the same supply, an interconnection between the no-volt relay of the motor circuit and the relay 3 is provided, so that the latter is de-energized whenever the main supply fails.

Title: Improvements in and relating to fibrous dielectric compositions
IPC: H01B3/48
Filed: 1948-07-30
Abstract: Fibrous materials having dielectric properties (see Group XXXVI) are produced by reacting a lignocellulose pulp with acrylonitrile in an aqueous alkaline medium until the fibrous material contains 0.3-2.8 per cent of nitrogen.  The fibrous reaction product may be made into paper suitable for use as a dielectric or electric insulating material (see Group VIII).  The lignocellulose pulp (i.e. mechanical wood pulp) is first suspended in the aqueous alkaline medium, which may be an aqueous solution of sodium hydroxide or potassium hydroxide containing for example 6-12 per cent of the alkali, and 30-70 per cent of acrylonitrile (based on the weight of the dry pulp) may be added to the continuously stirred suspension, which may be maintained at - 1 DEG  to 25 DEG  C. and preferably at 7 DEG  to 18 DEG  C.  The reaction may be stopped when the nitrogen content of the resulting product has reached the desired figure by adding sufficient dilute acetic acid to render the mixture slightly acid and subsequently filtering off the pulp and washing it with water until neutral. However, the reaction is preferably stopped by filtering the pulp from the reaction mixture and washing the pulp with dilute acetic acid and water until neutral.  In an example, 2.41 parts by weight of lignocellulose pulp are suspended in 44.4 parts of 6 per cent aqueous sodium hydroxide solution and stirred for 4 hours with 1.0 part of acrylonitrile at 10-15 DEG  C.  The reaction is stopped by drowning the mixture in a large volume of water, filtering off the pulp, and washing the pulp with dilute acetic acid and finally with water until neutral.  The nitrogen content of the modified pulp is 0.90 per cent. Pulps modified according to the invention may be formed into sheet material and impregnated with dielectric substances such as mineral oils or waxes, chlorinated hydrocarbons such as chlorinated benzene, chlorinated diphenyl, e.g. pentachlorodiphenyl, chlorinated diphenyl oxide, chlorinated diphenyl methane, chlorinated diphenylbenzene and alkyl derivatives thereof, tetrachloro-ortho-nitrodiphenyl, castor oil and derivatives thereof, and silicones.  These impregnated sheet materials may be used as dielectric spacers in capacitors of relatively small size (see Group XXXVI) and are said to have higher dielectric constants than similarly impregnated kraft papers.
