Title: Improvements in impedance measuring devices
IPC: G01R27/02
Filed: 1949-07-28
Abstract: 659,550. Impedance, loss angle, and Q-value measurements. RADIO CORPORATION OF AMERICA. July 28, 1949, No. 19885. Convention date, July 29, 1948. [Class 37] A circuit for measuring directly the Q-value and reactance of impedances and the loss angle of magnetic cores includes a vario-coupler and a phase shifter to which the impedance to be measured is connected in such a manner that the phase shifter can be adjusted to match the phase angle of the impedance and the variocoupler can be adjusted to give the magnitude of the reactive component of the impedance. The primary winding 12 of a vario-coupler 10 is connected in series with a resistor 18 and capacitor 16, the circuit being tuned to series resonance. An inductance 20, having a resistance 24, and a variable capacitor 22 are each connected in parallel with the series resonant circuit and together form a phase-shifting circuit. The three-branch circuit A is connected to one terminal 25 of a source of alternating voltage 26, the impedance 30 to be measured being connected between the circuit A and the voltage source 26 at terminals 28, 32. The secondary winding 14 of the vario-coupler 10 is connected in a detector circuit including a radio receiver or other detector 34 and a pair of terminals 36, 38. Normally the secondary circuit is connected in series with the impedance 30 by a lead 44 between terminals 28, 38. For initial adjustment the lead 44 is removed and a pair of air-core coupled coils 40, 42 are connected as shown. A purely reactive voltage is induced in the coil 40, and the capacitor 16 is then adjusted to make the current It through the impedance 30 and the current I 1  through the primary winding 12 of the vario-coupler 10 correspond in phase. The resulting setting forms a datum from which subsequent changes can be determined as the circuit is used to measure different impedances. If the coils 40, 42 are replaced by coils wound on a magnetic core whose loss angle is to be measured and the capacitor 16 adjusted to give a null indication in the detector 34, the change in capacitance is a direct measure of the loss angle of the core. The vario-coupler 10 may be of the wave-guide attenuator type. The variable capacitor 22 may be calibrated in Q-values.

Title: Improvements in or relating to electrical remote supervisory apparatus
IPC: H04Q9/00
Filed: 1959-06-12
Abstract: 869,396. Electric selective signalling systems. COMPAGNIE DES COMPTEURS. June 12, 1959 [June 16, 1958], No. 20196/59. Class 40(1). In a field station system in order to preven a field station transmitting data incorrectly to the central station each field station is called by two pulses, the first of which prepares or " readies " a field station to transmit if it has received a complete unit of data and the second of which actually causes the field station to transmit if it has been " readied." As a further safeguard these two pulses are followed by a third pulse which resets a " readied " field station, thereby ensuring that a field station can only be caused to transmit data by a pulse occurring at the correct time. As described, the central station I, Fig. 1, calls field stations, only one, II, being shown, successively by means of a rotary switch 22 and these calling pulses constitute the first pulses mentioned above. If a field station is prepared to be readied (i.e. if it has received a complete unit of data, this being represented by the positions of two switches 6 and 12) then a contact 5 is closed (by means not described) and the first call pulse from switch 22 energizes a relay 1 which is rendered slow-to-release by a capacitor 3. When relay 1 is energized the field station is " readied." The second pulse transmitted by the central station actually consists, as shown, of two pulses produced by switches 19 and 20 which make at least one revolution for each position of switch 22. These two pulses result in the energization of one of six coils 50 depending upon the positions of switches 6 and 12, the circuit being via a winding of a relay 8 and a contact 2 held closed by relay 1. Relay 8 causes a record of the data (i.e. the positions of switches 6 and 12) to be made at the field station. The third pulse produced by the central station is a pulse of earth and is transmitted by switch 22 to make relay 1 drop-out. After this switch 22 advances to its next contact and a further field station is interrogated.

Title: Improvements in rotor windings for commutating electrical machines
IPC: H02K23/30
Filed: 1951-08-29
Abstract: 690,205. Winding layouts for dynamoelectric machines. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 29, 1951 [Sept. 8, 1950], No. 20355/51. Class 35. The first or last coil in a slot to be commutated is split into two parallel conductors, one of which is disposed in the adjacent slot, the inductive energy caused by commutation being thus transfered to the slot which has just entered the commutation zone, and those coils which are commutated immediately after each other are adjacent in the same slot. To prevent circulating currents the two conductors of a split coil must have coil pitches respectively greater and less than the pole-pitch by the same amount, and for good cooling the number of coil sides located beside each other in the slot are less than the number of commutator segments per slot. As shown for a slot-winding having three coils 1, 2 and 3, the coil 1 is divided into two conductors 1<SP>1</SP> 1<SP>11</SP>, one of which is disposed in the adjacent slot in both coil sides so that conductor 1<SP>1</SP> has a pitch one tooth greater than the pole-pitch P, while conductor 1<SP>11</SP> has a pitch one tooth less. Equalizing connections may be connected to the commutator end of the windings.

Title: Improvements in and relating to electric discharge lamps
IPC: H01J61/04
Filed: 1946-07-09
Abstract: 646,369. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. July 9, 1946, No. 20499. Convention date, April 21, 1945. [Class 39 (i)] In a long gap low-pressure positive column discharge lamp with a coating of luminescent material on the interior wall of the envelope, and having a filling of starting gas and vaporizable metal, both of the thermionic electrodes 8 are surrounded by open-work metal screens 11 which have a floating potential during operation. As shown, the stem 2 flares at its inner end 3 so as to elastically distort the woven wire mesh screen 11 when it is slipped over the stem; the screen is thus held securely in place. A small lug 14 may key the screen in place, or the screen may be sealed to the stem. An exhaust tube 6 is provided, and the filling may be argon at 2-6 mms. together with mercury vapour at 10 microns. The thermionic electrodes 8 may be operated on A.C. or D.C. and may be used for hot or cold starting, and may be constructed as described in Specification 569,685, [Group XX]. The screens 11 may be of coarse or fine mesh and may be of uniform or non-uniform mesh. The front end 12 of the screens may be omitted, Fig. 3 (not shown). The screens are stated to reduce " spiralling " of the discharge, " anode oscillations " and end blackening." The Specification as open to inspection under Sect. 91 states that only one electrode need be provided with a screen 11, which may be of perforated sheet-metal or a closely-wound helix of fine wire. The filling may be of gas alone or of metal vapour alone. For D.C. operation only one of the electrodes may be thermionically emissive. Parts of the screen 11, such as portion 12, Fig. 2, may be imperforate, and parts such as the rear end or both the front end 12 and the rear end, may be left open. An imperforate disc or tube is, however, disadvantageous. The screen 11 should lie well within the Faraday dark space. In another embodiment, Fig. 4 (Cancelled), each electrode 8 is surrounded by two concentric tubular wire mesh screens 11, 16. The screens 16 are connected inside or outside the envelope 1 by a connection 15 of negligible resistance which is preferably broken after starting. If the outer screens 16 are omitted and the screens 11 are connected by connection 15, a resistance of ¢ megohm must be inserted in the circuit to prevent shorting out of the main discharge. This subject-matter does not appear in the Specification as accepted.
