Title: Improvements in electrical signalling systems and apparatus for use therein
IPC: H02J13/00
Filed: 1940-05-30
Abstract: 541,553. Electric signalling systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and MACKENZIE. J. F. May 30, 1940, No. 9468. [Class 40 (i)] In a system for the control of power-consuming units over the supply network by means of alternating currents interrupted at various slow rates or cadences, the actuation of a pushbutton or of a time switch causes a rotary switch FA to take up a position individual to the appropriate control signal, whereupon transmission takes 'place automatically for a pre-determined time. The system provides for 24 distinctive signals by the use of 4 different audio-frequencies supplied by alternators ATR1-4 and 6 different cadences. On the actuation of one of the push-buttons PB1-24, the switch FA steps to the corresponding position and energizes a self-locking relay IR which starts the common driving motor ACM of the alternators. After a short delay imposed by a motor-driven timing mechanism MS circuits are made over wipers of FA for one of the operating coils MCR1-4 of the contactors CR1-4 in order to supply direct current to the stator of the appropriate alternator and for one of the operating coils MC1-4 of the contactors C1-4, the latter circuit including appropriate cadence contacts. One of the cadence controllers 1RC, 2RC is connected up for one revolution, and just before completing the revolution it closes a releasing circuit for relay 1R, whereupon the motor ACM is stopped and the switch FA advances again. If any other push-button has been depressed, FA takes up the corresponding position, otherwise it stops in its home position. Lamps may be provided for indicating the condition of the units under control. Time switches for the control of street lighting comprise contacts tsd, closed at dusk and opened at dawn and contacts tsm closed momentarily at midnight. These contacts control relays 5R, 4R, which cause a rotary switch FB to move to positions 8, 16, 24 respectively at dusk, midnight and dawn in order to mark positions of the switch FA corresponding to the appropriate signals. In a similar way, certain positions may be marked by relays such as 2R, 3R controlled by remote push-buttons. For emergency use, duplicate cadence controlling apparatus under direct manual control may be provided, the motor ACM being started and the contactors CR1-4 being operated manually. Specifications 518,877 and 520,500 are referred to.

Abstract: 1,040,824. Metallurgical converter chimneys and hoods. PHOENIX-RHEINROHR A.G. VEREINIGTE HUTTENUND ROHRENWERKE. March 5, 1965, [March 7, 1964] No. 9515/65. Headings F4B, F4J and F4X. A heat exchanger for utilizing the waste heat from the waste gases of a converter comprises rows of water or water and steam carrying tubes 2, 3, 4 in a converter chimney 1, which rows are staggered in successive series transversely across the width of the said chimney and through the walls at each side thereof so that their projection on a plane perpendicular to the chimney occupies the whole chimney cross-section. The rows 2 of said tubes adjacent to the converter are preferably off-set by 90 degrees to the following rows 3. The said rows 2 carry water at a high speed and low temperature, and provide a turbulent gas flow ensuring early combustion of the carbon monoxide in the gas. The combined effect of the said rows 2, 3, 4 enables waste gases to be cooled to below 500‹ C., coarse dust to be extracted and little air to be entrained in the gas by infiltration, thus enhancing the heat transfer between the tubes and gases. The fine dust entrained may subsequently be removed in an electrostatic precipitator. The system may be used for both top and bottom blown converters.

Title: High Current Gate Controlled Switches
IPC: A41C1/02
Filed: 1969-02-25
Abstract: 1,196,576. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORP. 25 Feb., 1969 [6 March, 1968], No. 9926/69. Heading H1K. The Specification relates to a gate controlled turn-off thyristor having interdigitated cathode and gate electrodes in which carrier storage is reduced by decreasing the minority carrier lifetime in those parts of the base region lying below the spine of the cathode electrode. As shown, Fig. 5, the device is produced by lapping polishing and etching an N-type silicon wafer 30, producing P-type regions 26, 28 on both faces by pre-depositing boron from a B 2 O 3  source using nitrogen as a carrier and then driving-in simultaneously with an aluminium diffusion. The surface is oxidized, photomasked and etched, and phosphorus is predeposited using a P 2 O 3  source. The wafer is etched to remove phosphosilicates and then heated to drive-in the phosphorus to form N- type region 44 and simultaneously reoxidize the surface. A window is formed in the new oxide on the upper surface, the oxide on the lower surface is completely removed and a lifetime reducing impurity such as gold is diffusedin to form regions 50 and 52 by heating in a sealed capsule containing gold chloride. The cathode region 44 may be doped with arsenic instead of phosphorus to increase the penetration depth of the gold doped region 50. The cathode and gate regions 44 and 28 are contacted by electrodes produced by alloying aluminium to the surface to form layers 54 and covering with aluminium-silver layers 56 and silver layers 58. The electrodes may be produced by vapour deposition, masking and etching. A molybdenum. tungsten or tantallum plate 60 is bonded to the lower face of the body using an aluminium-silicon layer 62, and the edge of the wafer is etched to separate regions 26 and 28. Terminals (not shown) may be bonded to or held under pressure in contact with the cathode and gate electrodes. The region 50 underlies the spine 18 of the cathode electrode 14 which is provided with fingers 20 interdigitated with the fingers 24 of the gate electrode 16, Fig. 1. The lifetime reducing impurity may also be nickel, copper, iron, or manganese. Alternatively the impurity concentration of the upper base region (28) may be selectively increased beneath the cathode spine to reduce the minority carrier lifetime by diffusing-in boron for a P- type base region of phosphorus for an N-type base region. In such an embodiment boron is selectively diffused-into the upper surface of an N-type silicon wafer to produce a P-type region, and the wafer is then subjected to a boron or gallium and aluminium diffusion to produce the P-type upper base and anode regions and to a phosphorus diffusion to produce the N-type cathode region which crosses the initial P-type region. Gold is diffused into the lower face of the wafer and may also be present in the boron doped initial layer.

Abstract: 1319702 Acoustic delay lines SIEMENS AG 19 April 1971 [23 April 1970] 9972/71 Heading H3U A delay line comprises a polarized piezoelectric ceramic substrate 1 having transducers formed by input and output electrodes of interdigitated type. To adjust the transit time of the surface waves travelling between the transducers to compensate for manufacture tolerance variations the elasticity modulus of the substrate 1 is altered by producing an irreversible change in the remanent polarization by applying a required D.C. potential to auxiliary electrodes 5, 6. Preferably, the remanent polarization is adjusted by applying an electric field which is stronger than the coercive field strength in opposition to the remanent polarization of the substrate for a period whose duration is dependent upon the desired weakening of the polarization. The effect of the electric field on the substrate 1 is described with reference to a hysteresis loop (Fig. 2, not shown).
