Title: Apparatus for controlling and synchronizing clocks
IPC: G04G5/02
Filed: 1963-09-17
Abstract: 1,041,859. Time-signal controlled clocks. KOBUSIA DENKI KABUSHIKI KAISHA. Sept. 17, 1963 [April 15, 1963],No. 36596/63. Heading G3T. Apparatus for controlling and synchronizing clocks in dependence on a time signal which consists of one or more warning signals of a first frequency and a correct time signal of the same or other frequency, comprises a frequency selecting detector circuit F, D, a counting circuit C arranged to accumulate successive charges on a capacitor in response to the signals, a control circuit H, I arranged to discharge the accumulated charge on receipt of the correct time signal, and an electromagnetic device M for driving clock correcting means in response to discharge of the accumulated charge. By means of a low frequency electromechanical wave filter MF, the arrangement is designed to detect signals from a radio receiver (not shown) of 1000 c/s at input 1, consisting of fire warning pulses followed by a correct time pulse, Fig. 1 (not shown). The signals are amplified and supplied to a rectifier network D, in which a series capacitance C 0  and parallel inductance L provide a high-pass filter to supplement the circuit F. Circuit D includes a relay A operated by the stable rectified output of a transistor having a diode in the emitter circuit. This initiates operation of the counting circuit C, in that the contact a of relay A closes to discharge C 1  thereby actuating a relay B to close a contact b 1  and open a contact b 2 . The potential at input 2 of a time holding circuit H changes from +ve to -ve. This triggers a monostable multivibrator to actuate a relay E for a time interval T e . Contact e closes to energize an integration circuit I in which the junction of R 5  and C 5  goes to the base of a transistor whose emitter circuit includes a relay F which is actuated later than the energization of relay E. The output of the integration circuit I is applied to the magnet circuit M. Capacitor C 3  in the counting circuit is progressively charged by the warning pulses. By setting the operating voltage of relay G higher than the terminal voltage V 6 , and setting relay F to operate with the arrival of the last pulse of the correct time signal, relay G is operated in the time Tg. By designing relay F to operate over a time interval T f  which terminates later than the time announcing pulses so as rapidly to discharge the spurious voltage of C 3 , erroneous operation is avoided.

Title: Improvements in or relating to methods of treating silicon-iron alloys
IPC: C21D1/78
Filed: 1956-11-30
Abstract: A method of heat treating silicon-iron alloys containing 2-5 per cent silicon in which the alloy is subjected to hot deformation followed by one or more cold deformations and a final heat treatment comprises carrying out the final heat treatment in an atmosphere in which the partial pressure of oxygen is so low as to prevent the combination of oxygen with silicon on the surface of the alloy or, alternatively, to cause the disappearance of any oxygen combined with silicon which may already be present, for a time and at a temperature so related that recrystallization results in a cubic structure.  The temperature may be above 950 DEG C., preferably between 1100 and 1350 DEG C., and the atmosphere may be hydrogen of dew point between -25 DEG C. and -40 DEG C., or a mixture of hydrogen and argon, or the treatment may be preformed in a bath of molten metal.  A getter material for oxygen may be present in the furnace, e.g. sheets of silicon-iron may be separated by sheets of aluminium or titanium, or an oxide of magnesium aluminium, alkaline earth metals or rare earth metals may be used.  A substance which acts catalytically to convert molecular hydrogen to atomic hydrogen may be present e.g. nickel, platinum, or alloys thereof or a ceramic substance having such a metal sintered therewith.  The final cold deformation may be 50 per cent to 75 per cent to produce sheet or strip between 0.35 and 0.003 mm. thick and the heat treated strip may be shaped before a treatment in hydrogen at 600 DEG C. to 1000 DEG C. Specification 442,211 is referred to.

Title: Improvements in or relating to conversion of crude oil into more valuable hydrocarbons
Inventor: MURRAY MAURICE JACKSON
IPC: C10G47/00
Filed: 1954-12-21
Abstract: <PICT:0761847/IV(b)/1> A process for treating a crude oil comprises distilling the oil and recovering gasoline and a residual fraction, reforming at least a portion of said gasoline under conditions that result in a net production of hydrogen, deasphalting at least a portion of the residual fraction, hydrocracking at least a portion of the deasphalted material in the presence of hydrogen from the reforming step to produce gasoline and treating at least a portion of the latter gasoline in the reforming step.  Distillation of the crude oil may be effected at atmospheric pressure under vacuum with the assistance of steam.  Deasphalting may be effected by means of a solvent such as propane used at a temperature of 16-93 DEG  C.  In a prepared process, a crude Kansas oil having a specific gravity of 0.8348 is passed through line 1 into a distillation column 5 in which some gas together with light naphtha is removed overhead via line 6, and a straight-run naphtha boiling at 66-204 DEG  C. is withdrawn through line 8, and reduced crude is removed through line 13 to deasphalting unit 15 in which it is deasphalted in a tower-type operation with propane. The resulting deasphalted oil passes through line 18, and is commingled with recycled hydrogen from line 20 and is then passed through heater 22 where it reaches a temperature of 285 DEG  C. and it then passes through line 23 to the hydrocracking zone 24 where it passes over a catalyst consisting of 3 per cent of nickel on silica-alumina.  Kerosene and fuel oil are removed via line 25 while the gasoline is removed via line 27 and is combined with the straight-run naphtha withdrawn from column 5 and after admixture of hydrogen from line 23 is reformed in vessel 35 using a catalyst comprising 0.3 per cent weight of platinum on alumina containing 0.18 per cent of combined fluorine, at a temperature of 477 DEG  C. and a pressure of 47.5 atmospheres.  There is a net production of hydrogen at the reforming step which is more than sufficient to meet the demands of the hydrocracking step.  Specification 657,565 is referred to.

Title: Improvements in and relating to the production of isotactic polystyrene fibers
IPC: D01D5/08
Filed: 1959-11-02
Abstract: 940,621. Polystyrene filaments. UNION CARBIDE CORPORATION. Nov. 2, 1959 [Oct. 31, 1958], No. 37047/59. Heading B5B. Isotactic polystyrene filaments having uniform molecular orientation are made by extruding isotactic polystyrene having a melt index from 1 to 30, through a die at from 230-330 C. to form a continuous filament, hot drawing the filament as it emerges from the die through a heated zone maintained at a temperature at least as high as the extrusion temperature and not higher than 330 C. without permitting the temperature of the filament to fall below the extrusion temperature until all the filament molecules are completely relaxed, and thereafter bringing the filament to a temperature of 120-140 C. and cold drawing the filament at this temperature to a degree sufficient to induce molecular orientation in an amount of 750- 900%. The heated zone may be a heated liquid bath containing an inert non-solvent for polystyrene, or a heated gas stream, or, as described below, a heated chimney of metal or refractory material capable of withstanding elevated temperatures. Preferably, the melt index of the polystyrene is 2-20, extrusion is effected at 250-300 C., and cold drawing at 125-135 C., at a rate of 200-3000 ft./min. to a ratio of at least 8.5: 1. Isotactic polystyrene of melt index 1-30 may be obtained by pyrolysis of isotactic polystyrene of melt index 0.01-1.0 at 325-425 C. After extrusion and hot-drawing, the filaments may be cooled and wound on bobbins or drums prior to cold-drawing. As the hot-drawn filaments are brittle when cold, they are heated, after the cooling step, to 75-100 C. before winding. Preferably, however, hot-drawing and colddrawing are carried out as a continuous process, without an intermediate wind-up step. In Fig. 1, isotactic polystyrene fed into hopper 10 is forced by a screw extruder into a heated zone 16, held at 230-250 C., then into a second heated zone 18 held at 250-290 C., and then into extrusion die 12, at 230-330 C. The extruded filaments are maintained at the die temperature by means of the heated chimney 14, hot-drawn and passed around pulley 20 at a temperature sufficient to prevent the fibres from being too brittle for handling, but at which the polymer will not flow or permit orientation. The tow is now passed around rolls 22, through which the force is applied to the filaments in the relaxing chimney to effect the hot-drawing, heat being supplied from infra-red lamps A to prevent cracking of the filaments while passing around rolls 22. Next the tow is cold-drawn in bath 24, suitably of glycerine, maintained at 120-140 C., force being applied through godet 26. Fig. 2 shows the extruder head construction. The extruder head and spinning die are maintained at the required temperature by an electric band heater 40, and chimney 42. close to the die orifices, and preferably attached to the die shown, is heated by heater bands 44, the temperature of the chimney interior being measured by thermocouple 46. Specification 823,306 is referred to.

Filed: 1961-10-16
Abstract: A process for the catalytic hydrogenative treatment of lubricating oil or wax in which the oil or wax to be treated is passed at elevated temperature through a reaction zone together with a gas containing hydrogen comprises bringing the oil or wax to reaction temperature by passing it through one or more heat exchange zones in which indirect heat exchange is effected with the gas containing hydrogen, which has been heated to a temperature higher than the temperature at the beginning of the reaction zone, preferably 10 DEG -100 DEG C. higher, and mixing the gas containing hydrogen which has been used for this heat exchange with the oil or wax at one or more points situated upstream and/or downstream of the heat exchange zone or zones, and/or between such zones.  The oil or wax may have been preheated to a limited extent prior to the heat exchange.  The mixture entering the reaction zone may contain 100-1000 m.3 of gas (S.T.P.) containing hydrogen per ton of oil or wax, suitably a pressure of 125 kg./cm.2 is employed in the reactor, using a catalyst such as CoO/MoO3/Al2O3, with an inlet temperatur of 340 DEG C. and an outlet temperature of 375 DEG C.  Specification 275,248 is referred to.
