Abstract: 662,424. Electric indicating systems. WESTERN ELECTRIC CO., Inc. Dec. 16, 1949. [Dec. 18, 1948] No. 32331/49. Class 40 (i). A relay circuit for distinguishing between signals of different potential comprises a chain of relays R1 ... R5 each connected through a rectifier RC1 ...RC5 to a source of different biasing potential P1 ... P5 so that each relay responds to a different minimum signal potential, the relays being so connected that only the relay appropriate to the magnitude of the D.C. potential P will respond. As shown, a potential of below 20 volts applied at P will cause actuation of relay R5 which breaks the circuit of relays R1 ... R4 and lights lamp L5; a potential of between 20 and 30 volts applied at P actuates relay R4 which breaks the circuit of relays R1 ... R3 and lights lamp L4; similarly, higher potentials actuate relays R3, R2 and R1.

Title: Improvements in and relating to magnetic saturation devices

Abstract: 670,838. Inductances; automatic regulation; converting. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 16, 1949 [Dec. 31, 1948], No. 32351/49. Classes 38 (ii) and 38 (iv). A standard reference voltage or current is obtained across or in a circuit 19 from an A.C. supply 15 by including in the circuit a saturable reactor 1 comprising a laminated core and a permanent magnet 8 which provides a flux in a main path 4, 5, 6, 7 including air gaps 11, 12, and in a shunt path comprising a pair of coilcarrying limbs 9, 10 of material having a sharp kneed saturation characteristic, e.g. nicaloi (equal quantities of nickel or iron) and which are saturated by the flux of the permanent magnet. The pair of coils 13, 14 are seriesconnected in opposition so that the limbs are desaturated in succession by the A.C. giving a constant and substantially rectangular current waveform through resistance 19, which current may be rectified by rectifier 18. Alternative core constructions are described, Figs. 6 and 7 (not shown), which in one arrangement the symmetrical core comprises two main central limbs having the permanent magnet between them and two outer coil-carrying limbs. A closed conducting loop 34 may be provided around the magnet to avoid demagnetization by the A.C. Compensation for supply voltage and frequency variation may be effected by providing an additional winding 23, 24 on each limb acting in opposition to the magnet flux and connected through a rectifier 27 either across a condenser 25 connected in series with an adjustable resistance 26 across the A.C. supply or through an inductance, shunted by an adjustable resistance, to the A.C. supply, Fig. 8 (not shown). The main windings 13, 14 may be connected in series as shown, or in parallel, each through a rectifier in opposition so that one coil only carries current at any instant (Fig. 9, not shown), or included the two upper or lower arms of rectifier bridge 18, Fig. 13 (not shown), or in the outer leads of a centretapped transformer secondary winding connected through push-pull rectifiers (Figs. 10- 12). In the latter arrangement an additional winding may be provided on each limb to induce an E.M.F. in the main winding to prevent overlapping of current through the main windings, the additional winding being connected either in series with the main winding on the other limb or in the common lead between centre tapping and resistance 19.

Abstract: 583,022. Gas turbines. WHITTLE, F. Dec. 19, 1939, No. 32477. [Class 110 (iii)] The walls of the rotor of a gas turbine are cooled by a flow of air induced by running blades 15 carried by the rotor in co-operation with outer fixed blades 13 which secure a radial delivery of the air. On the inlet side of the turbine, air enters by an annular duct 10 and is discharged through a duct 11 and pipe 16 as a supply of useful warm air. The air is delivered by the blades 13 at a pressure sufficient to prevent entry of the working gas into the air stream. The blades on the exhaust side, which are optional, draw air in through an orifice 8b and discharge it into the turbine exhaust. The turbine may be part of a jet propulsion plant as described in Specification 456,980, [Group XXXIII]. According to the Provisional Specification, the cooling air may be used to augment the propulsion jet, or, to drive auxiliary apparatus.

Abstract: 352,357. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Lynn, L. H. ; 115, Elmer Avenue. Schenectady, New York, U.S.A.) Nov. 4, 1930, No. 33181. Convention date, Nov. 4, 1929. [Class 40 (v).] A thermionic generating system comprises two valves in push-pull with the output circuit of a third valve coupled to their input circuit, the load circuit of the single valve being balanced with respect to the cathode by connecting an intermediate point on the load circuit to the cathode and providing a balancing capacity between one side of the load circuit and the cathode. The tuned load circuit 4 of the screen-grid high frequency amplifier 1 has the mid point of its tuning condenser 6 connected to earth, as is the cathode. The capacity to earth of the upper part of the inductance 5, consisting of the anode-cathode capacity and condenser 15, is balanced by connecting the lower end of 5 to the cathode through a balancing condenser 16. This ensures that the opposed-phase voltage fed to the push-pull amplifiers 2, 3 is equal, ensuring stability and freedom from parasitic oscillations in circuit 4. The output circuit 13 may be tuned to a harmonic of the frequency of circuit 4.
