Patent GB-1123347-A (GB)
Title: Testing of inductive windings
Inventor: JAMES RONALD EDWARD
IPC: G01R31/06
Filed: 1964-10-05
Abstract: 1,123,347. Detecting and locating faults. ENGLISH ELECTRIC CO. Ltd. Oct. 5, 1965 [Oct. 5, 1964], No. 40602/64. Heading G1U. The position 10 of a breakdown in an inductive winding such as the secondary winding 6 of a transformer is located by connecting the ends of the winding to earth points through inductive reactances 7, 9 and applying a high test voltage V, across the primary winding 5 so that a high frequency arcing discharge takes place at point 10. The ratio of high frequency voltages V 3 , V 2  developed across reactances 7, 9 is indicative of the position of the breakdown. A capacitor 8 may be interposed between inductive reactance 9 and winding 6 to reduce the voltage across inductive reactance 9. In a modification a null detector 11, Fig. 3 (not shown) is connected at one end to reactance 7 through a voltage varying device 12 and at the other end to reactance 9. A phase shifter (not shown) may be interposed between one pair of reactances 7, 9 and device 12. Device 12 is adjusted to give a null position on detector 11 and the setting of device 12 thereby indicates the ratio of voltages V 3 , V 2  and hence the position of the breakdown. Test voltage V 1  may be induced in the winding to be tested or it may be applied across the winding through a direct connection. A single inductive winding may be tested in this manner. The reactances 7, 9 may be replaced by capacitors or resistors, or a combination of such electrical impedances.

Title: Method for producing a cold rolled rimmed steel sheet or strip
IPC: C21D3/08
Filed: 1963-10-15
Abstract: A cold-rolled rimmed steel sheet or strip, with non-ageing properties and deep drawability, contains: <TABS:1057124/C6-C7/1> the remainder being Fe and impurities.  The steel is produced by adding P and at least one of Sb, Bi, Nb and Pb to molten steel containing:  .C.0.02 to 0.15%, .Mn.0.15 to 0.6%, .P.less than 0.01%, conventionally hot and cold rolling the resulting rimmed steel, and decarburizing and denitriding annealing e.g. at between 500 and 750 DEG C. the sheet or strip in an atmosphere e.g. moist hydrogen with or without nitrogen, which decreases the C and N contents to the desired final values. The rimmed steel may be prepared by adding Fe-P, Fe-Mn and metallic Sb or Pb to conventional open-hearth or electric furnace or converter steel.

Title: Improvements in or relating to flue gas rotary regenerative preheaters
Inventor: ALLISON JAMES NORMAN
IPC: F28D19/04
Filed: 1964-10-07
Abstract: 1,116,627. Thermal regenerators. JAMES HOWDEN & CO. Ltd. 30 Sept., 1965 [7 Oct., 1964], No. 40981/64. Heading F4K. In a thermal regenerator in which air is heated by flue gases, ammonia is injected into the flue gases in the regenerator, to minimize corrosion by sulphuric acid. As shown, the heat transfer matrix 3 is a pervious metal mass formed in two parts or zones positioned respectively upstream and downstream in the flue gas flow and means are provided for introducing the ammonia into the flue gas between the parts or zones to inhibit metal corrosion by the acid in the downstream zone of the matrix. The flue gas enters the regenerator through an inlet 7 and leaves through an outlet 9. A baffle 12 is arranged between the zones and directs the gas into a U-shaped duct 13 through which it is guided by vanes 14. Liquid ammonia is introduced into the duct 13 through an opening 15. The ammonia forms a non-corrosive salt which is deposited on the downstream matrix and from which it can be periodically removed by washing or soot-blowing, the resultant sludge being removed through an outlet 17. The invention is said to be applicable to regenerators having stationary air and gas ducts 7, 9, 10, 11 and a matrix rotating on a vertical or horizontal axis; and also to rotary duct-stationary matrix regenerators. Cleaning doors 16 (Fig. 2, not shown) are provided in the regenerator casing.

An A.C. motor is supplied by a converter providing a variable frequency output to give variable speed, and control for the converter is derived from a pair of reluctance type A.C. generator devices having rotating parts driven by the motor shaft. As shown, a rotating part 23 comprises a magnetic semi-cylinder 24 and a non-magnetic semi-cylinder 25. Two magnetic cores 41, 42 for each phase are disposed about the part 23, one above and one below, each bearing a winding fed from a high frequency generator 321 or 322 and connected with oppositely directed rectifiers 211, 221, so that according as whether the magnetic half 24 completes the upper or lower magnetic circuits so a voltage E 2  is derived in one sense or the other. An exactly similar device is associated with the other rotating part 13, but the magnetic and non-magnetic semi-cylinders are displaced by 90 degrees on the shaft. A voltage E 1  is derived from this device, the voltages E 1 , E 2  being alternating voltages having the frequency of the rotor and being 90 degrees phase displaced. These two are added to give a voltage E 5  which is used to control the inverter, similar voltages being derived for the other phases of the three phase supply. To increase speed the phase of the voltage E 5  is advanced, this being effected by varying the magnitude of E 1  relative to E 2  by control of the high frequency generators.
