Title: Improvements in single-phase compound motors
IPC: H02K27/04
Filed: 1952-08-08
Abstract: 709,354. A.C. commutator machines. SPAHR, O. Aug. 8, 1952 [Aug. 15, 1951], No. 20061/52. Class 35. A compound single-phase motor comprises an armature 1 and a stator 5 which are both laminated, the stator having poles 6, 7, upon which are arranged the series field winding 2 and the shunt field winding 3. A condenser 4 is connected in series with the shunt field winding and is so dimensioned that the shunt circuit is tuned to the frequency of the mains, the operation in the resonance range tending to keep the shunt field current at a steady value under different conditions of loading. The connection of the condenser also reduces the phase displacement between the shunt field and armature currents, thereby reducing sparking at the brushes. The transformer coupling between the windings 2, 3 reduces the series field excitation at light loads due to countervoltage induced in the winding 2, the shunt field excitation being similarly reduced when the load is heavy.

Title: Artificial line and method of making same
IPC: H04B3/40
Filed: 1943-12-01
Abstract: 571,772. Artificial lines. STANDARD TELEPHONES & CABLES, Ltd. Dec. 1, 1943, No. 20065. Convention date, Aug. 8, 1942. [Class 40 (iii)] An artificial line comprises a permalloy or like strip separated by a strip of insulating material from a grounded strip of conducting material and means for tapping the permalloy strip at any desired point. The strips may be straight, as shown in Fig. 4, the permalloy and insulating strips 40, 41 being wedge-shaped in cross-section to give a more uniform distribution of current. Where the line is short, it is grounded through a resistance 47 equal to the characteristic impedance of the line. In other arrangements -similar strips or, as shown, parallel-sided ones, are bent into a spiral, Fig. 1, in which case the arm 30 for making the adjustable contact is telescopic, or a helix, Fig. 5 (not shown), in which case it is movable along its shaft. In all cases in which the strips are bent, it is necessary to avoid stresses in the permalloy, e.g. by making it very thin and giving a large diameter to the spiral, by extruding it initially so that it builds up in a helical shape or by submitting the bent strip to an annealing process.

Title: Separation of protactinium from molten salt compositions
IPC: G21C19/50
Filed: 1961-06-05
Abstract: Protactinium is separated from a fused fluoride salt composition by reacting the composition with a metal oxide which will form a fluoride and precipitate protactinium oxide.  Suitable oxides are those of Li, Na, Rb, Be, Ca, Zr, Al, U, and Th, preference being given to oxides corresponding to the fluorides present in the fused composition.  The oxide may be added to the composition and precipitated protactinium removed by filtration; or the fused salt may be passed through a porous column of the oxide.  In examples, BeO, CaO, ThO2, and uranium oxide are added to composition containing fluorides of Be, Li, and Th, and small amounts of Pa233 \sB Pa231. The process may also be used for separating protactinium from uranium-containing natural sources.  The residue from treatment of pitchblende with nitric and sulphuric acids, or the carbonate precipitate from treatment of the acid extract of pitchblende with sodium carbonate, may be dissolved in a fused fluoride composition and treated according to the invention.

Title: Improvements in and relating to circuit arrangements for measuring a component of analternating current or an alternating potential
IPC: G01R1/28
Filed: 1936-07-21
Abstract: 470,303. Power-factor and resistance measurements. SIEMENS & HALSKE AKT.-GES. July 21, 1936, No. 20212. Convention date, Aug. 3, 1935. [Class 37] In the measurement of a component of an alternating-current or potential, an auxiliary circuit is provided in which a balancing current equal in magnitude to a selected component (other than the measured component) is set up, the measured and balancing components being fed differentially to a transformer, the output circuit of which contains the measuring instrument and a phase adjustable rectifier. A condenser 1, the loss-angle of which is to be measured and a variable standard condenser 2 having no losses are connected to primary windings of a differential transformer 3. The difference current produced in the transformer secondary winding due to the differential flux action is rectified by a phase-controlled vibrator winding fed separately from a secondary winding 7 on the main transformer. The measuring currents are fed from a tapped secondary winding 9 and the sensitivity of the instrument is adjusted by parallel resistances 12 and 14, 15 variable respectively with the potential adjustment 10 and capacitance adjustment 13, these adjustments making the instrument reading independent of capacity and potential. In making a measurement of phaseangle loss, the rectifier is energized in phase with the secondary potential 9 and the capacitance 2 is varied until the instrument reads zero. The phase-shifter 6 is then adjusted through 90‹ and the deflection on the instrument is then a measure of the loss-angle of capacitance 1.
