Title: Improvements in or relating to thermionic valve arrangements
IPC: H03F1/16
Filed: 1936-12-31
Abstract: 475,457. Valve generating circuits; thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. (Telefunken Ges. f³r Drahtlose Telegraphie) Dec. 31, 1936, No. 35893. [Classes 39 (i) and 40 (v)] In a short-wave or other high-power transmitter in which a transmitter valve R is balanced by a capacitively equivalent but inactive neutralizing valve' or other capacity network N, the working valve R is arranged coaxially with the neutralizing valve or network N, the two grid connections being adjacent to one another with the cathode lead K arranged coaxially inside the grid lead G. The grid leads are thus shortened, back-coupling is eliminated, and inter-anode capacity is reduced. Except for ultra-high-frequency working a parallel-connected live valve may be used for the neutralizing valve. Radiation damping may be checked by screening the anodes, but alternatively the whole system may act as a radiating dipole. The feeder E may be matched to the valves. The two valves may have a common glass envelope, the output energy being taken off capacitively, so that a short lead can be used for connecting the grids ; this lead has small inductance and thus determines a high frequency. The filaments He, Fig. 3, are axially arranged and the grid-anode capacity is adjustable. When a second valve N, as distinct from an artificial capacity network, is used for neutralizing purposes, the valves may be used in turn to economize their life. Alternatively, if the unit is not to be used as a dipole radiator, they may both be active and may be used in parallel. In a push-pull arrangement two pairs of valves are required, as shown in Fig. 4. Thermionic valves. In a short-wave transmitter in which the active valve R is balanced electrostatically by an inactive valve N, the two valves are arranged coaxially so that their grids can be connected by a short lead G containing a coaxial cathode lead K. The glass structures Gl, Fig. 1, of the valves are borne by supports H. The valves may have a common evacuated envelope, the glass part of which is seen at V, Fig. 3, so that a short lead may be used for connecting the grids Gi. Each cathode He, Fig. 3, may consist of a thick axial wire and a number of thin outer return wires. In order that the capacity between grids and anodes may be adjustable, the anodes are mounted on resilient glass or metallic concertina portions Z of the envelope. Aerials. The transmitting valve R and capacity-neutralizing inactive valve N, mounted coaxially base to base, may function as a radiating dipole. Thus the feeder only carries the control energy. Several such dipoles, united in phase, may be built up into a directive transmitting system.

Title: Polymers containing carbonate and carbamate groups
IPC: C07C49/813
Filed: 1958-11-12
Abstract: New copolyesters contain the residues of carbonic acid, a bis carbamic acid, a dihydric phenol, and possibly a dihydric alcohol. Preferably, the number of carbonate groups is at least twice the number of carbamate groups.  The polymers may be made (a) By reacting a bis-chloroformate of a dihydric phenol with a diamine and a dihydroxy compound in the presence of a hydrogen halide acceptor, block type copolymers being produced when the bis-chloroformate is added to a mixture of the other two reactants or when the diamine is first mixed with the bis-chloroformate and the dihydroxy compound is then added, and more regular copolymers being produced when the diamine and the bis-chloroformate are added to a pool of the dihydroxy compound; (b) By reacting a dihydric phenol, a diamine and a bis-chloroformate of another dihydroxy compound as in (a) above; or (c) By reacting a dihydric phenol with phosgene in the presence of a hydrogen halide acceptor to produce a low molecular weight polycarbonate with chloroformate end groups and then reacting this polycarbonate with a diamine and also, possibly, a dihydroxy compound. Specified dihydroxy compounds are di-(monohydroxyaryl)-alkanes, 4:41-thio-bis(3-methyl-6-tertiary butyl phenol), resorcinol, catechol, ethylene glycol, di-, tri- and tetra-ethylene glycol, propylene glycol, 1:3-propanediol, 1:4-butanediol, 1-butene-3:4-diol, 1:4-butenediol, thiodiglycol and phthallyl alcohol.  The diamine may be one of formula <FORM:0906012/IV(a)/1> where X is an oxygen or sulphur atom or a sulphide, sulphoxide, sulphone, hydrocarbon or substituted hydrocarbon radical or it may be ethylene-, propylene-, trimethylene-, tetramethylene-, hexamethylene-, o- or m-phenylene or 1:7-naphthylene diamine; or 4:41-diamino dicyclohexyl methane, bis-(o -aminoalkyl) sulphides, 2:4-diaminotetrahydrofurane, 1:4-diamino cyclohexane, 4:41-diamino benzophenone, piperazine, o-toluidine or m-toluidine.  The polymers are soluble in organic solvents (e.g. methylene chloride) but may be rendered insoluble by heating them with a diisocyanate or a diisothiocyanate (many specified).  They may be used in the manufacture of coatings, electrical insulation materials, transparent windows, films or fibres.  In examples, polymers are obtained by reacting (1)-(4) The bis-chloroformate of bis-phenol A, bis-phenol A and p,p1-diaminodiphenyl methane or hexamethylene diamine; (5) A low molecular weight polycarbonate of bis-phenol A with chloroformate end groups and ethylene diamine; (6) and (7) Bis-phenol A, the bis-chloroformate of diethylene glycol and the dihydrochlorides of 4:41-methylene dianiline or hexamethylene diamine, the products being reacted with toluene diisocyanate; (8) Bis-phenol A, the bis-chloroformate of diethylene glycol and p,p1-diaminodiphenyl methane, the product being reacted with 1,5-naphthalene diisocyanate.
