Filed: 1943-04-21
Abstract: 565,870. Valve amplifying circuits. SCANTLEBURY, G. S. P., and WHITE, E. L. C. April 21, 1943, No. 6443. Addition to 564,250. [Class 40 (v)] An amplifier of the kind described in the parent Specification, in which a thermionic valve arranged as a cathode follower is connected in series with a further valve so arranged that the two valves feed the load in opposite phase, is modified to enable a single source of power to be employed. The circuit comprises a first and second pair of similar valves, the anode-cathode paths of each pair being arranged in series in the same sense across the source, and the load being arranged to receive the current in opposite senses from each of the valves of each of the said pairs. The input is applied in such a manner that the valves of each pair are excited in opposite phase and corresponding valves of the two pairs are excited in phase opposition, the contributions of all the valves to the load being additive. The Figure shows pairs of valves 1, 2 and 1a, 2a with the signal applied to the valve 1 which feeds an out-of-phase signal to the valve 2. The load 5 is connected between the cathodes 3, 3a so that a voltage is applied to the cathode 3a of the valve la so that this valve is driven in phase opposition to the valve 3. The valve 1a feeds an out-of-phase voltage relative to its input to the valve 2a. A common cathode resistance 15 may be provided in series with the valve pairs to maintain accurate balance. One terminal of the input circuit and of the load may be earthed. A bias resistance may be inserted in series in the cathode lead to the valve 1. Each valve in the system may be replaced by a number of valves in parallel.

Title: Improvements in or relating to a process for the production of bodies of cross-linked polymeric material
IPC: C08J3/28
Filed: 1958-02-28
Abstract: A body of cross-linked polymeric material is produced by irradiating in an inert gas stream with corpuscular or electromagnetic radiations having at least the energy of ultra-violet rays, a polymeric material capable of being cross-linked by such rays, said material being in powder form, and subsequently working the powder to form the body e.g. by injection, pressing or extrusion.  Specified polymers are those of which the chain and branch members consist only of carbon and hydrogen (polyethylene, natural rubber, synthetic rubber, poly-p-xylylene) and those of which the chain and branch members contain also other atoms, e.g. nitrogen, oxygen or sulphur (polyvinyl alcohol, polyacrylonitrile).  Specified radiations are X-rays, g -rays, fast, slow or thermal neutrons, electrons and ultra-violet rays from a high- or low-pressure mercury discharge tube.  The radiation may be derived from a nuclear reactor.  The irradiation may be performed by moving the powder past a number of sources of radiation and the powder may be maintained at a temperature above 20 DEG C. but below that at which the particles cohere.  For polyethylene 60 DEG -70 DEG C. is suitable; polyethylene when so irradiated and formed into plates exhibits no "memory effect."
