Title: Improvements relating to variable speed induction motors
Inventor: HETZEL PETER JOHN GRENVILLE
IPC: H02P27/02
Filed: 1961-07-19
Abstract: 992,014. Control of A.C. motors; electric converting systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 13, 1962 [July 19, 1961], No. 26180/61. Headings H2F and H2J. The speed of an induction motor M is varied by injecting a variable A.C. voltage at slip frequency into its secondary winding, using static electronic switching devices, to buck or boost the slip voltage. By increasing a bucking voltage the motor is slowed, and by increasing a boosting voltage the motor speed can be increased above synchronism. The voltage is derived from a variable transformer T connected to the three-phase supply to the motor primary which may be the rotor. The switching devices X, preferably transistors or semi-conductor controlled rectifiers, are triggered to connect each end of each secondary winding S1 . . . S3 to the three-phase output of T in a sequence which results in the windings receiving effectively a six-phase supply, which it is stated improves the wave shape of the injected voltage. The triggering is effected by a timing unit U, coupled to the motor shaft, which provides pulses at a frequency such that the resultant frequency of the injected voltage is that of slip. Details are given (Fig. 2, not shown) of the manner in which the semi-conductor devices are used to switch A.C. (using a rectifier bridge) and the way in which they are automatically " extinguished. It is stated that the secondary windings could be in star formation, and that the power factor can be controlled by adjusting the phase angle of the triggering pulses. Specification 926,099 is referred to.

Title: A process for the preparation of adenosine 5-triphosphate and salts and esters thereof
IPC: C07F9/6561
Filed: 1960-08-03
Abstract: Adenosine-51-triphosphate (A.T.P.) or a salt or ester thereof is obtained by reacting adenosine 51-phosphoramidate, the amidate group of which may be substituted, or an organic or inorganic base salt thereof, with pyrophosphoric acid or an acid ester or salt thereof. The amidate group may be substituted on the N-atom by one or two alkyl, alkenyl, or aryl groups or it may be derived from a heterocyclic nitrogen base e.g. morpholine, piperidine or piperazine. The organic base salt of the phosphoramidate may suitably be a salt with dicyclohexyl guanidine, N-(3-oxapentamethylene) guanidine or N-(pentamethylene) guanidine.  The pyrophosphoric acid or ester thereof is one having the formula:-  HO.P(O)(OR3).O.P(O)(OR4)(OR5) wherein R3, R4 and R5 are hydrogen or an alkyl, aryl or aralkyl group.  When the pyrophosphoric acid is used in the form of a salt it may be an alkali metal or alkaline earth metal salt or an organic base salt.  When the product is an ester the ester can be converted to A.T.P. by hydrolysis with an alkali or preferably by hydrogenolysis especially when the ester is the benzyl ester.  The hydrogenolysis can be effected in the presence of a palladium or platinum catalyst.  The reaction is generally carried out in an organic solvent, e.g. pyridine, acetonitrile, cresol, or o-chlorophenol and may be conducted without the application of heat. The A.T.P. can be recovered from the reaction mixture as its alkali metal, mercury or barium salt and may be purified by absorption on e.g. activated charcoal or an ion exchange resin and then eluted with a suitable solvent.  Alternatively, an organic solvent may be added to a highly concentrated aqueous solution of an alkali metal salt of A.T.P. to precipitate the salt.  Specified methods are by the reaction of tribenzyl pyrophosphate with the N-(3-oxapentamethylene) guanidinium or dicyclohexyl guanidinium salt of adenosine 51-phosphoramidate, and by the reaction of bis-triethylammonium pyrophosphate with the cyclohexylammonium- or dicyclohexylguanidiniumsalt of adenosine 51-phosphoramidate.

Abstract: 831,715. Electrotherapeutic apparatus. DIAPULSE MANUFACTURING CORPORATION OF AMERICA. Aug. 22, 1958 [Oct. 4, 1957], No. 27047/58. Class 81 (2). Electrotherapeutic apparatus comprises an H.F. oscillation generator and amplifier, the output of which is controlled by a pulse generator and fed to a tuned output circuit. This results in high-frequency oscillations being administered to the patient in controllable, pulsed bursts whereby the total heating effect is kept within tolerable limits. A piezo-crystal 37, connected to a valve 38, feeds oscillations to a doubling circuit 46, 47, the output of which is passed to a further frequency-doubling stage 50, 65 coupled to a radio-frequency amplifier 8 comprising two tetrodes in push-pull. Control pulses are derived from a generator assembly 6 in which parallel-connected oscillator valves 27, 28 are supplied with high-voltage anode current received from a full-wave power pack 5, containing a tapped auto-transformer 15 and a step-up transformer 18. The pulse length is controlled by a switch 33, which varies the effective capacity of the grid-condenser assembly 32, while the pulse frequency is controlled by a switch 35, which determines the magnitude of the grid leak 34. The amplitude of the pulses is determined by the transformer tapping switch 16 and the pulsed output is connected through a step-up transformer 36, which is connected as the anode feed for the amplifier valves 55, 56. Consequently the H.F. output is dependent on the flow of anode current from transformer 36 and passes as a series of pulses of H.F. current through transformer 73 and coaxial cable 74 to a tuned circuit 13 in the applicator head.
