Title: Improvements relating to temperature control means for magneto-strictive delay lines
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H03H9/36
Filed: 1956-11-14
Abstract: 813,591. Automatic temperature control. SIEMENS EDISON SWAN Ltd. Oct. 17, 1957 [Nov. 14, 1956], No. 34819/56. Class 38 (4). The temperature of a magneto-strictive delay line is maintained constant by varying a heating current therethrough in accordance with its electrical impedance. In one embodiment, unbalance of a D.C. bridge B, Fig. 1, having the delay line D in one arm, is detected by the control winding CW of a saturable reactor S, the main winding MW of which is in series with an A.C. source T1, rectifier Rf and the input of the bridge. When the line D approaches the required temperature, the bridge approaches the balance point and the bridge current, and hence the line heating current, approaches zero. To avoid overheating the line, in abnormal conditions, e.g. during setting up, the circuit is rendered responsive to unbalance in one direction only by the inclusion of rectifier Rf2 in the circuit of the control winding CW. In a modification the bridge current is derived from a transistor amplifier controlled by the rectifier circuit including the saturable reactor, Fig. 2 (not shown), or the transistor amplifier may be replaced by a magnetic amplifier. In an embodiment using an A.C. bridge and line heating current, the bridge B1, Fig. 3, including the line D is supplied from the A.C. source through winding W3 of a transformer TF2. The out-of-balance potential is applied via transformer TF1, and transistor amplifier TS2, to the other winding W4 of transformer TF2 to augment the bridge current flowing through winding W3. If the bridge becomes unbalanced in the abnormal direction the amplified output of transformer TFl is in opposite phase and diminishes the bridge current. Series and shunt rectifiers Rf4 and Rf5 are connected in the collector-emitter path of transistor TS2 to protect the latter from positive excursions of the applied A.C.

Abstract: 783,102. Digital electric calculating apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 30, 1955 [Dec. 2, 1954], No. 34970/54. Class 106 (1). Zero resetting arrangements for electronic multi-cathode tube type of counter include means for applying a reset pulse to each stage and simultaneously applying a pulse to the carry-over apparatus to render it inoperative during the resetting operation. The zero cathode Ko of each counter tube is connected through a resistor Ro to a bus-bar RBB which delivers a negative reset pulse to each zero cathode and also, via a condenser C4, to the trigger electrode of each transfer tube T, thus rendering ineffective the carry-over arrangements. Rectifier W1 prevents overswing from affecting the tube T, and rectifier W2 allows ordinary cathode current to pass from the zero cathode Ko while presenting a high impedance to the reset pulses applied at terminal A. The carry-over arrangements are described in Specification 782,433.

Patent GB-422592-A (GB)
Title: Improvements in and relating to processes for recovering vanadium from pig-iron
IPC: C22B34/22
Filed: 1933-12-14
Abstract: Vanadium is recovered from pig iron by adding a strongly basic and very liquid slag to the molten pig iron before or during oxidation of the vanadium, removing the slag as soon as the vanadium is completely oxidized, and recovering vanadium or its compounds from the slag. The basicity of the slag may be determined by the presence of sodium or potassium compounds, ferrous oxide, or manganous oxide.  When the molten iron is run directly into the slag, preliminary oxidation of the vanadium may be promoted by increasing the distance through which the iron drops, by supplying air enriched with oxygen or steam to the iron, or by adding to the iron substances adapted to yield oxygen such as red iron ore or slags containing ferrous oxide.  Prior to removal of vanadium, the pig iron may first be freed from silicon by the use of a slag rich in silicic acid; in this case oxidation of the vanadium during following treatment with the basic slag may be promoted by addition to the slag of metallic oxides, such as red iron ore.  After removal of vanadium, refining of the pig iron may be completed.  The Specification, as open to inspection under Sect. 91, states p  that the basic character of the slag may be determined by the use of pig-iron containing manganese, or by adding manganese ores or manganese-containing slags to the slag.  This subject-matter does not appear in the Specification as accepted.ALSO:Vanadium is removed from pig iron by adding a strongly basic and very liquid slag to the molten pig iron before or during oxidation of the vanadium, and removing the slag as soon as the ionadium is completely oxidized.

Title: Improvements in or relating to electronic circuits embodying transistors
Inventor: CHAPLIN GEORGE BRIAN BARRIE
Filed: 1953-12-17
Abstract: 763,735. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 16, 1954 [Dec. 17,1953], No. 35209/53. Class 106 (1). [Also in Group XL (c)] A number of two-state transistor circuits are combined to indicate the presence of none, one, some or all of a number of input signals. The input signals may be of pulse form occurring simultaneously or sequentially in an electronic digital computer. Each transistor operates in a circuit of the type described in Specification 747,606 in which two of the electrodes are supplied from constant current sources in the on condition and are limited to certain potential levels in the off condition. In the on condition, the electrodes of transistor T1, Fig. 1, are all near the collector potential while in the off state the emitter is held near earth due to diode D5 conducting, diode D1 holding the base near +2. In the on condition of transistors T2, T3, T4 the electrodes are all near the collector potentials which are biased increasingly negative. Clock pulses a and signal pulses band c are applied to the cathodes of diodes D1, D2, D3, the pulses band c also being fed through an and gate to diode D4. An a pulse triggers transistor T1 on to indicate that no signals has been received but if either b or c is applied the current through resistor R1 is diverted to transistor T2 or T3, transistor T1 remaining in the off state. When both a band c are received transistor T4 operates, biasing off the emitters of the other transistors. The circuit is reset by a negative pulse applied to the cathode of diode D5, and output pulses may be derived from the bases of the transistors. In a modification, Fig. 3 (not shown), loads are arranged in the collector leads to give larger output currents. In a further modification, Fig. 4, for serial operation a diode gate D14, D15 and D16 is arranged between transistors T11 and T12. Transistor T9 operates in each case and is reset by operation of T 10 or T11. When pulse b is followed by c, the latter passes through diodes D14, D15 since diode D16 is biased off due to the fall in emitter potential of transistor T10. Transistor T12 passes to the on state, resetting the other transistors. Positive input pulses. A positive a pulse, Fig. 7, allows the anode of diode D17 to rise carrying the emitter temporarily positive to switch transistor T13 on, the base and collector becoming slightly negative with respect to earth. In a similar manner, inputs band c are effective to switch on transistors T14 and T15, the rise in collector potential of either raising the anode potential of the corresponding diode D18 to feed a positive resetting pulse to the base of transistor T13. The collectors of transistors T14, T15 are also connected over diodes forming an and gate to the input of transistor T16. When both band c pulses occur the transistors T14, T15 trigger transistor T16. The circuit is reset by pulses applied over diodes to all the bases and outputs are taken from the collectors.
