An electric pulse generator comprises a pair of electrically connected alternators on the same shaft, and means for periodically providing a limited, angular displacement of at least one of the stators with respect to its rotor to change the relative phases of the two generator voltages to produce a desired net output. As shown, mutual angular displacement of the stators 12, 13 is produced by means of a gear-driven cam 24 and cam follower 23 operating a lever 15, pivoted at 16, and engaging lugs 18 and 19 on the stators. In a modification, the stator and rotor slots are oppositely skewed in the two machines so that relative axial movement between the stator and rotor cores varies the phase of the output voltages (Figure accompanying Complete Specification, not shown). In another form, the rotors are mounted through skewed splines on a common shaft such that axial movement of the rotor on the shaft results in relative angular movement between the rotors and causes a phase change in the voltages. The stators may be combined into a single pack.

Patent GB-804341-A (GB)
Title: Process for the manufacture of trisubstituted boranes
IPC: C07F5/02
Filed: 1957-05-06
Abstract: Boranes of the formula R3B are prepared by introducing a boron halide of the formula BX3 and a compound of the formula RY into a mixture of alkali metal and a dry ether maintained at 20 DEG  to 60 DEG  C., R being a hydrocarbon radical selected from aliphatic, alicyclic and aromatic radicals, and X and Y being halogen atoms.  Suitable halides are the alkyl halides, preferably the lower alkyl halides having from one to five carbon atoms in the alkyl group, such as methyl iodide, ethyl bromide, isopropyl chloride and t-butyl chloride; aryl-substituted alkyl halides such as benzyl chloride, chloromethyl toluenes, or chloromethyl naphthalenes; alicyclic halides such as cyclohexyl chloride and cyclopentyl bromide; or aryl halides, such as bromobenzene and a -bromonaphthalene.  As boron halides, boron trifluoride, boron trichloride, boron tribromide or their etherates may be used.  The alkali metal is preferably used in the form of wire, shavings, pellets or as a fine dispersion in an inert medium. Lithium, sodium and potassium are suitable alkali metals.  The lower dialkyl ethers containing not more than five carbon atoms in each alkyl group are preferred solvents, but cyclic non-reactive ethers can also be used.  Examples include diethyl ether, di-n-butyl ether and tetrahydrofuran.  The stoichiometric ratio of 3 gram mols. of organic halide and six gram atoms of alkali metal per mol. of boron halide is preferred but a slight excess of boron halide or organic halide may be used. The proportion of alkali metal is preferably sufficient to combine with all the halogen of both reactants.  It is convenient to dissolve the two halide reactants in separate or the same ether solution and introduce them into a vessel containing the alkali metal covered with ether with vigorous stirring.  The heat of reaction may cause refluxing but additional heat may be supplied. The process may be operated continuously, the effluent stream being filtered to remove alkali metal halide, fractionated to recover the trisubstituted borane and the solvent and unreacted halides being returned to the reaction zone.  In examples: (1) n-butyl chloride is reacted with boron trichloride in the presence of sodium and ether to give tri-n-butyl borane; (2) n-butyl bromide is similarly reacted with boron trifluoride giving the same product; (3) n-propyl bromide is reacted with boron trichloride in the presence of lithium and ether giving tri-n-propyl borane; (4) monochlorobenzene and boron trifluoride etherate are reacted in the presence of lithium and ether to give triphenyl-borane; (5) bromobenzene and boron trichloride are reacted in the presence of sodium in ether to give triphenylborane. The products may be used in motor and diesel fuels or for synthetic purposes.

Abstract: 378,527. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, O'DONOVAN, D. E., Russetts, Vicarage Road, and NIXON, L. R., Totnes, Main Road, Broomfield Park Estate, both in Chelmsford. May 15, 1931, No. 14472. [Class 40 (v).] Relates to keying-systems of the kind employing a key-controlled valve SAV directly coupled to an absorbing valve AV connected across the main transmitter valve (not shown), and consists in arranging a protective device R in the grid circuit of the valve AV which passes current only when the grid voltage rises above a safe value. Keying is effected by applying alternately positive and negative voltages from a source SP to the grid of the valve SAV, and thus, owing to the presence of a resistance SAR in its plate circuit, causing the plate voltage to vary. These variations are passed through a bias source NB to the grid of the absorber valve AV, causing this valve to take or to block plate current through the resistance AR, and so varying the high tension supplied at CD to the transmitter valve. In normal operation, no current passes through the protective device R and source ABP, but in the event of the filament or filament supply of the valve AV failing, its grid is prevented from attaining an undesirably high voltage by the device R becoming conductive. The device R may comprise a copper oxide or other rectifier, a neon tube, or a spark gap.
