IPC: G05F1/33
Filed: 1961-10-31
Abstract: 992,709. Rectifying. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 31, 1961, No. 38930/61. Heading H2F. A rectifying arrangement as disclosed in Specification 823,537 in which a control voltage is applied to modify the reset flux of the saturable reactors, and hence the output voltage, comprises a rectifier MR1 forwardly biased by a battery B1, the control voltage being applied between points D and E. Fig. 2 shows the condition when input terminal A is positive and contactor X is closed. A forward circulating current I 1  flows through MR1, and with no control voltage a smaller reset current I can effectively flow in the " reverse " sense. If a positive control voltage is now applied producing I 2 , the maximum value of I will be reduced since I+I 2  cannot exceed I 1 . Figs. 3 and 4 (not shown) disclose the half wave when contactor Y is closed and a full wave arrangement respectively.

Title: Improvements in or relating to method and plant for drawing a glass strip
IPC: C03B18/04
Filed: 1963-10-03
Abstract: <PICT:0988128/C1/1> <PICT:0988128/C1/2> <PICT:0988128/C1/3> In the drawing upwardly of a glass strip 11 from a layer 3 of plastic glass which moves forward to the drawing position 6 sliding on a bath 2 of molten material and in which both surfaces of the foot 15 of the strip are cooled as by coolers 16, 17, the layer of plastic glass is prevented from flowing on the bath 2 of molten material beyond the foot 15 of the strip by cooling its front surface 18 to a degree sufficient for this freely flowing surface, because of the increase in viscosity, to be continuously entrained to constitute the front surface of the strip.  To protect the bath 2 of molten material from the cooler 17, a screen 19 is interposed below the cooler 17 with a polished surface 21 closely adjacent the bath 2 and with the end 20, of carbon or boron nitride, close to the surface 18 so that the end 20 acts as a stop to the free flow if the cooling is insufficient. The bath 2 below the drawing position is maintained at the required temperature by longitudinally movable controllable resistors 22 in sheaths 23 and the edges ahead of the drawing position by resistors 221 in sheaths 231. The edges of the layer 3 in the compartment ahead of the drawing chamber are prevented from touching the side walls 26 by coolers 25 above the edges, screens 27 preventing cooling of the bath 2 and heaters 29 maintaining the temperature of the bath 2.  As normally, edge grippers 14 are provided and as in Fig. 3, the strip 11 is passed over a roller 10 and then on to rollers 13 in an annealing lake 12 or as in Fig. 6, the strip 11 is further cooled at 161, 171 and passed between rollers 36 in a vertical annealing lake 35.  As in Fig. 6, the screen 19 may be a separate member, forming a continuation of the usual L-block 30.  In a modification, the screen has a further cooling member closely adjacent to the surface 18 and replacing the end 20, with a heat insulating lower surface. In place of the special combined cooler 17 and screen 19 shown in Fig. 3, the screen 19 may be hooked over a cooler similar to cooler 16.  In a modification of Fig. 3, the front end 20 is replaced by a carbon plate which is kept immersed in the bath 2 with its upper edge below the level of the foot 15, the carbon plate being adjustable vertically by pivoting the screen 19 about the cooling pipes 44.  A similarly pivoted, immersed carbon plate may replace the screens 27 and coolers 25 to prevent the edges of the layer 3 reaching the side walls 26.

Title: An apparatus for supporting an element from a floating marine platform
IPC: E21B47/00
Filed: 1965-09-16
Abstract: 1,092,247. Wells &c. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Sept. 16, 1965 [Sept. 18, 1964], No. 39579/65. Heading E1F. The effect of the vertical movement of a floating platform on an element supported by the platform is compensated by apparatus comprising means to measure the vertical movement, and an actuating device coupled to or forming part of the measuring means and causing vertical movement of the element in response to vertical movement of the platform. A drilling vessel 10 supports a manipulator 20 adjacent a wellhead 15 by means of a line 21 passing over a pulley 23. A line 36 is anchored to the sea bed and runs around a drum 25 which is connected by a line 24 to the pulley 23. The drum is subjected to a constant torque sufficient to support the manipulator and keep the line 36 in tension so that increase or decrease of the distance of the vessel from the bed is accompanied by corresponding lowering or raising of the manipulator relative to the vessel. The constant torque is derived from the actuating device comprising a hydraulic cylinder 31 which is supplied with pressure fluid from a compressed air tank 32. In a modification (Fig. 2, not shown) the vertical movement is measured by an anchored line (71) which is connected to a transducer (66) generating electrical signals according to the length of the line, the signals being supplied to a controller (67). The signal from the controller actuates a control valve (61) to supply fluid to or exhaust fluid from one end of the actuating device 51, the other end of the actuating device being supplied with fluid under pressure sufficient to support the element (44) which is a drill pipe supported by the free end of the hoisting cable which is attached to the rod of the actuating device. A device (68) detects the position of the rod to send a signal to the controller to stabilize the system.

Abstract: 1365598 Switching diodes COMMISSARIAT A L'ENERGIE ATOMIQUE 25 Aug 1972 [10 Sept 1971] 39799/72 Heading H1K A switching diode for use as a binary store comprises a semi-conductor substrate, a thin layer of vitreous, insulating material uniformly doped by ion implantation to a density of at least 10<SP>20</SP> atoms/c.c. on a surface of the substrate and an overlying electrode of metal which, in the forming of the device by avalanching, is incapable of diffusing through the insulating layer. As described the substrate is a wafer of 5 ohm cm. P- or N-type silicon 200-300 Á thick, the insulating layer is of thermally grown silica, or silicon nitride 1000 Š thick and the electrode of molybdenum 0À3-0À5 Á thick. Any of the elements between boron and argon in the Periodic Table may be used as dopant, but phosphorus and aluminium are prepared. Implantation is performed in a series of stages in which the ion energy and flux are progressively reduced, and may be followed by a 15 minute anneal at up to 500‹C. Forming is effected by application of 50 volts of either polarity with the avalanche current restricted to 100 ma/cm.<SP>2</SP> A further forming step may be employed in which a progressively increasing positive voltage is applied until at a current of 0À5 mA the device switches to a high resistance condition. In operation switching from a low to a high resistance state occurs on application of a positive bias above a threshold value and reversion to the low resistance state on application of a sufficient negative bias.

Abstract: 1,139,275. Voltage regulators. RADIO CORPORATION OF AMERICA. Sept. 4, 1967 [Sept. 29, 1966], No. 40248/67. Heading G3X. The effectiveness of a voltage stabilizing device of the breakdown type, e.g. a Zener diode, is improved by maintaining the current through the device at a constant value. As shown, a voltage regulator comprises input terminals 10, 12 and a Zener diode 18 across which the stabilized output voltage is developed for application to load terminals 14, 12, the Zener diode being associated as indicated with transistors 20 and 30 of opposite conductivity types. The arrangement is such that variations in the current through Zener diode 18 are sensed by transistor 20 which controls the conductivity of transistor 30 to compensate for these variations, the transistor 30 acting as a variable shunt path across the Zener diode 18.
