Title: An installation for making ingots
Inventor: PATON BORIS EVGENIEVICH
IPC: B22D11/08
Filed: 1969-05-16
Abstract: 1,219,707. Casting processes; electroslag refining. INSTITUT ELEKTROSVARKI IMENI E.O. PATONA AN UKSSR. 16 May, 1969 [22 Nov., 1968], No. 24997/69. Heading B3F [Also in Division H5] In an electroslag refining apparatus ingots are produced by fusing electrodes 6 through a slag bath 17 in a cooled mould 13 having a widened mouth 16. The total cross-sectional area of the electrodes is preferably 0À8 to 1À2 times that of the lower part of the mould 18. At the beginning of the process the mould 13 rests on a stool 14 with the projection 21 lying just below the tapered part of the mould. As refining proceeds the mould is moved upwardly to free the lower part of the ingot 19 which is surrounded by a heat insulating screen 22 to retard cooling and thereby prevent the ingot cracking. When refining is completed the solidified ingot is removed on a truck 15.

Title: Stabilising arrangement for oscillators in high frequency apparatus for signal transmission
IPC: H03D7/10
Filed: 1937-09-15
Abstract: 492,624. Valve generating circuits. COLE, Ltd., E. K. Sept. 15, 1937, No. 25036 Convention date, May 15. [Class 40 (v)] Variation of frequency of a radio-frequency oscillator with variation of one or more of the energizing voltages, (e.g. grid bias) is prevented by the provision of a supplementary feedback circuit so designed that the reactive effect of the valve on the frequency determining circuit is compensated. Fig. 3 shows an oscillator 3 with magnetic coupling between the anode inductance 9 and the tuned grid circuit coil 10. With such an arrangement variation of the mutual inductance of valve 3 due, e.g. to variation of grid bias will result in a variation of the total impedance across points 1 and 2, and the tuning of circuit 10, 11, 12 will be varied. According to the invention a feed-back circuit comprising resistance 5 and condensers 6 and 11 is provided, the circuit constants being chosen so that the inductive effect of the valve on the impedance across points 1, 2 is neutralized by an approximately equal capacitative reactance fed back over condenser 6. The invention is mainly directed to prevention of detuning in superheterodyne receivers when a strong A.V.C. voltage is applied on weak signals to a frequency changer 24 of the pentagrid type as shown in Fig. 7. The oscillator anode 29 is back-coupled to the tuned circuit 34, 35, through inductance 39, while the capacity feed-back circuit comprises resistance 41 and condenser 57. The A.V.C. circuit is conventional, the control being applied to the I.F. amplifier 46 and the frequency changer 24. The effect of the variation in mutual conductance of 24 on the frequency of tuned circuit 34, 35 is compensated by the capacity feed-back 57. The invention is also applicable to stabilization of frequency in transmitting oscillators. Specification 383,981 is referred to.

Abstract: 604,266. Feeding ammunition to guns. NASH, A. F. Sept. 13, 1935, No. 25505. [Class 92 (ii)] The desired degree of slackness in an ammunition belt 7 is obtained by connecting the mounting of the gun 1 as by a link 17 with an arm 18 which, when the gun is trained, causes rotation of the spindle 10 around which the magazine 8 rotates. Further, in the path of the belt there is a roller 14 mounted on a lever 15 whose other end 15 serves to operate braking mechanism 21 for the magazine. In the construction shown a Bowden cable 23 extends from the end 15 to a two armed lever 20 which is pivoted to the arm 18 and carries the brake shoe for the magazine 8, and the arrangement is such that the normal pull on the belt when firing the gun serves to release the brake shoe from the magazine.

Title: Improvements in or relating to the production of fused anhydrous salts and caustic alkalis
IPC: C01D17/00
Filed: 1951-11-02
Abstract: Fused anhydrous salts or caustic alkalis, e.g. sodium nitrate or caustic soda, are produced from aqueous solutions thereof by rapidly super heating a melt of the substance, quickly thereafter adding the solution to the melt maintained as a shallow stream, removing steam, and recovering the fused anhydrous salt.  In <PICT:0706441/III/1> Fig. 1, sodium nitrate is melted in pot 10, and pumped, at say 312-365 DEG  C., through nozzles 17 over baffles 16 in tower 15. Therein it is heated to 350-400 DEG  C. by hot gas from heater 18 circulated by fan 23.  Entrained drops of sodium nitrate are removed by baffles 24.  The superheated melt flows as a stream over baffles 28, and a concentrated neutral solution of sodium nitrate, at say 80 DEG  C., flows in through duct 29.  The net make of salt is pumped to spray nozzles 38, the droplets descending tower 36 against a current of air from fans 39.  In a modification, the conical base of tower 15 is provided with baffles defining a serpentine or concentrically circulating path for the fused material which flows therethrough to the central opening, the nitrate solution being passed in to the outside path.

Abstract: 319,478. Rymal, R. L. Sept. 7, 1928. Actuating pumps by motion of vehicles; regulating compression.-A tyre inflator actuated by rotation of a wheel comprises a cylinder divided by a wall into a piston chamber and a compressed air chamber connected with it through a check valve and containing a tube disposed to prevent flow of lubricant but allow flow of air to the tyre. The pump cylinder is formed as a part of the hub; a delivery chamber 20 in its end is formed bv a partition 19 containing the inlet and outlet valves. The incoming air is filtered by a screen. The compressed air passes from the chamber to the tyre through a tube 39 extending nearly to the partition, so that lubricant is prevented by the centrifugal force from entering. The piston is driven by an eccentric 25 on the axle. A chamber on the side of the cylinder contains a diaphragm 44 subject to the air from the cylinder entering through a port 56 and acting against a spring 52. This diaphragm opens a valve 48, allowing escape to atmosphere when the pressure rises unduly. Oil also escapes into the diaphragm chamber through the port 56.

As shown a switch 14 is used to select one of three frequencies at terminals 15, 16, 18 of a frequency divider 12 to drive a liquid crystal display 30. A switch 40 ganged to the switch 14 activates a corresponding one of decimal point indicators 33a-c to show that the display is in thousandths, hundredths, or tenths of a second. Counting is started and stopped by a switch 52 which controls a NOR gate 20 via logic circuitry 51. In the RESET position of the switch 52, counter 22 and the display 30 are set to zero. A further embodiment is envisaged which can also be used as a reaction timer or for starting races. In this mode, a randomly variable delay is introduced between the operation of a push-button switch (52a), Fig. 5 (not shown) and the inititation of counting. As counting starts, a transistor (94) is triggered to light a lamp (70). The next operation of the switch (52a) stops the counter, and a third operation resets to zero. If the STOP operation is performed before the end of the variable delay, a flip-flop (86) in the logic circuitry is reset to sound an alarm. Other forms of display are envisaged.

The annular induction heating coil which surrounds the rod to form the molten zone may also be inclined to the vertical. In a modification the melt is produced by a heating device e.g. an electron beam which acts from above on the rod so that the melt is heated on one side to approximately the centre of its cross-sectional area and the monocrystalline rod is drawn from the melt outside the heated part i.e. from the flow of the melt arising from tilting the feed rod. Figure 1, shows a silicon monocrystal being drawn by seed crystal 5 from melt 4 located in a graphite container 2 which is surrounded by a heating coil 1 whilst the entire system is inclined to the vertical and both the crucible 2 and seed crystal 5 are rotated. In a modified arrangement, not shown only the axis of the crucible is inclined to the vertical.
