Title: Starting a pour in continuous casting plant
IPC: B22D41/52
Filed: 1976-07-16
Abstract: 1523025 Tundishes; ladles CONCAST AG 16 July 1976 [18 July 1975] 29817/76 Heading F4B [Also in Division B3] When starting to pour steel, to delay the filling of a continuous casting mould, to a specific level, so that there is time for solidification to provide an adequate shell and for coupling with a dummy bar head before starting to withdraw, a fusible tubular choke 12 (e.g. of steel containing 0À1-0À7% C, and to reduce the flow rate by 10-60%) is inserted in the bottom pouring nozzle 2 of a tundish 1 ; it melts away after a time determined by its size and material. The choke 12 may be squeezed to a slight ovality to wedge at a desired level. A ledge 20 may be provided in the nozzle 2 so that the choke is held always at the same level. To prevent the steel first entering the tundish from freezing in the nozzle 2, a cover, such as a metal plate 21 calculated to melt when the steel in the tundish 1 is a few centimetres deep, or an asbestos plate, is placed over the nozzle. The tundish 1 with its outlet cover may be preheated. The 20-60 mm. long choke 12 may have a heat insulating coating, e.g. of brushed-on Zr paste, and its flow cross-section may be 30-60% of that of the unchoked nozzle 2. It may be of a material having a higher melting point than the steel cast.

Title: Improvements in carburettors for use in connection with internal-combustion engines
IPC: F02M19/03
Filed: 1920-10-25
Abstract: 174,435. Parker, W. R. Oct. 25, 1920. Spray carburettors.-The fuel-inducing value of the depression in the region of the jet orifice is varied by admitting to such region a variable supply of compensating-air through a valve controlled independently or in conjunction with the throttle valve. A jet from the fuel tube c<3> discharges into a chamber c<4> whence capillary ducts c<5> deliver into air passages c<1>, the resulting emulsion being delivered through nozzles c<2> in the manner described in Specification 116,792. From the chamber c<4> a fixed tube a' extends upwardly along the axis of a barrel throttle valve b, and is provided at its upper end with a cone a<x> having a series of radial ducts a<4>. These ducts admit the compensating air, and are controlled by a valve a<3> actuated preferablv from the throttle valve. For this purpose, the throttle valve has a tubular extension b<2> carrying another tubular part b', to which the actuating arm b<3> is secured. The part b<4> has a tongue b<8> adapted to engage notches in the head a<7> of the spindle a<6> of valve a<3>. By raising and rotating the head a<7>, adjustment of the valve a<3> relative to the throttle valve may be effected. The valve a<3> has a port a<5>, which may register more or less with a port b<5> in the tubular part b<4>. The compensating air may therefore be graduated in quantity or cut off altogether, but it is such that it is reduced as the throttle is opened. The nozzles c<2> may decrease in height from the air intake towards the outlet side of the mixing-chamber. In a modification, a single nozzle may be arranged along the axis of the throttle valve and deliver fuel into a smallbore Venturi tube, primary air for breaking up the fuel being admitted through a calibrated passage in the base of the nozzle.

Oct. 11, 1930, No. 30485. Convention date, Oct. 16, 1929. [Class 60.] Guides and rests.-A machine for grinding long tapered articles, for example, rifle barrels, golf club shafts, &c. comprises means for feeding the work axially through the throat between the grinding-wheel and the regulating- wheel of a centreless grinder, and timed mechanism for varying the width of the throat. The machine consists of a base 15 having thereon a grinding-wheel 17 and on a slide 18, a support 19 for a regulating-wheel 21 movable towards and from the wheel 17 by a screw 23 engaging a nut in the support 19. The wheel 21 also may be moved by rotation of the nut, through gearing operated by a pinion 53 on a shaft 54 and rotated by a rack 52 on the rod 51 of a piston 50 movable in a cylinder 49 carried by a bracket 48. The bracket also has therein a chamber 54<1> for a ported bushing 55 containing a control valve 65 having therein spaces 66 .. 69 ; fluid is supplied by a source 42 from a reservoir 47 and conduits 43 .. 46 ; the conduit 45 has therein an adjustable choke valve 60. The valve 65 may occupy three positions, in one of which fluid is admitted to the top of piston 50 and exhausts freely from below the piston through the conduit 44, in the second of which the exhaust is restricted by the valve 60 giving a slow movement for feeding during grinding, and in the third of which the direction of movement of the piston is reversed, thus retracting the regulating-wheel after grinding is completed. The work is supported in the throat by a rest 30 and outside the throat by members 34, 35, being fed axially by a member 40 carried by a rod 38 and retracted axially after grinding by an ejector 39 on the rod 38 ; the rod 38 is moved by a belt, chain, &c. 89 passing over a member 90 carried by the shaft 54, and the shape of the member 90 may be such as to give a variable speed to the rod 38. The movements of the valve 65 are controlled by a cam plate 73 movable with the rod 51 and having parts 74, 75, 76 engaging a spring-pressed latch on the arm 79 of a lever 78 connected to the stem 84 of the valve. When the lever is depressed, the movement is rapid until the latch moves on to the part 76 of the cam when grinding proceeds with slow movement of the parts ; when the latch moves off the part 76 the lever is lifted by a spring 801 up to a stop - and gives the reverse movements to the parts. The grinding-wheel and the regulating-wheel may be of tapered form with shaped edges ; the axis of the regulating-wheel may be inclined to assist, or to oppose, the axial traverse of the work.
Patent GB-211196-A (GB)
Title: Improvements in or relating to submarine mines
IPC: F42B22/18
Filed: 1922-11-08
Abstract: 211,196. Vickers, Ltd., and Elia, G. E. Nov. 8, 1922. Mines, marine. - A submarine mine is automatically anchored at the desired depth by means of an auxiliary line which is paid out from the sinker while the main mooring rope is also being paid out; the upper end of the line is connected to the mine or to the upper end of the main mooring cable and is adapted to be released therefrom at the desired depth. This release stops the mooring cable drum in the sinker. In the form shown in Figs. 2 and 3, the sinker B and the mine, A are secured together before launching by a combined time and hydrostatic release Q, as described in Specification 210,873. The mooring cable C and the auxiliary line F are paid out of the sinker B from two drums D, E rotating in opposite directions on the same fixed spindle G<1>, the drums acting as brakes to each other by frictional engagement at H. The upper end of the mooring cable C is attached to the mine A by means of a tension-controlled safety device, as described in Specification 212,971, to delay the separation of the mine from the sinker at the beginning of the launching operation. The upper end of the line F is connected by a link g<1>, Fig. 3, to a. socket g<7>, which is attached to the stem g<6> of an hydrostatic device G on the mine A by a shear wire g<10>. When the mine is launched and falls below the desired depth before its release from the sinker, the diaphragm g<2> is forced up by hydrostatic pressure and the stem g<6> of the diaphragm confines balls g<8> in holes in the socket g<7> and in the casing of the hydrostat, the socket being thus locked to the hydrostat. When the launching operation is nearly completed and the mine has risen to the desired depth, the balls g<8> are released by the hydrostat, the wire g<10> is sheared by the pull of the line F, and the drum E is driven in thel reverse direction by the drum D through the braking engagement H. This reverse rotation of the drum E drives a ratchet wheel K by means of a pawl J<1>, and a detent plate L fixed to the wheel K releases a pawl M, which is urged by a spring N into locking engagement with a toothed wheel d on the drum D, thereby stopping this drum. In some modifications, the two drums are mounted on a screwthreaded spindle or on parallel screw-threaded spindles and follow each other, so that when the line drum ceases to rotate it acts as a stop to the mooring-cable drum, or the line drum works a nut which acts as the stop for the mooring-cable drum. In another modification, the pull of the auxiliary line normally holds a spring pawl away from a ratchet wheel on the mooring-cable drum; and when the line is released, the pawl locks the drum. A suitable form of hydrostat for the present purpose is described in Specification 163,339.

Oct. 26, 1934, No. 30795. Convention date, Feb. 2. [Class 17 (i)] Lasting.-In a heel-seat lasting-machine, the bars for driving the tacks into the wiped-over margin of the upper are stationary during the advance of the wipers, but are adjustable to correspond with the adjustment of the wipers for size of shoe. The mass moved by the wiper-actuating cam is thus decreased, this being specially advantageous when the cam is formed to cause several reciprocations per cycle. For each side of the heel, the tacking mechanisms 21 are carried by a sector 20 above and independent of the sector 8 for the corresponding wiper 9. The sectors 8 are swung by the usual pinions 11, 12 gearing with a normally stationary toothed slide 13. For adjusting the initial position of the wipers for size of shoe, the slide 13 is moved by a screw 14 actuated by bevel gearing and a hand-wheel 17. So that the tackers may be correspondingly adjusted, pinions 26-28 for swinging the sectors 20 are provided, the first pinion gearing with teeth on a slide 24 adjustably connected to the slide 13 by an eccentric on a pin 23 carried by the latter slide. The slide 6 which advances and retracts the wipers and causes them to swing is actuated by a cam 4 providing at least three reciprocations of the wipers per cycle.
