Title: Method and apparatus for continuous casting of metal strips
IPC: B22D11/041
Filed: 1972-07-18
Abstract: 1385985 Continuous casting NORANDA MINES Ltd 18 July 1972 [30 Sept 1971] 33565/72 Heading B3F A cast strip 25 of Cu or Cu-based alloy such as brass, bronze, Ni-Ag, cupronickel or Al-Zn is withdrawn in a stop-start sequence from a mould 5 of non-wetting material (graphite) directly connected (possibly removably) to the bottom of a tundish 10 which is heated (as by burners 12 in an insulated container 16); the mould 5 is cooled by liquid (water from pipes 23 and a channel 24 adjacent a bulging mould-portion 7) applied directly to the mould and then allowed to flow on to the emerging strip 25. The top narrow portion 6 of the mould 5, with a tapering seal 8 is mainly in the heat-conducting bottom 17 of the tundish 10 and includes thermocouples 9. A bath of molten metal of a depth 4-6 times the width of the mould cavity crosssection is contained mainly in the mould portion 6. The water-flows on to the two mould sides are separately controlled to maintain the temperature at the solidification level above or near the melting point of any alloy constituent which has an appreciable vapour pressure. To prevent oxidation of the vapour, a neutral or reducing atmosphere may be introduced into the gap between the strip and the mould wall. The cast strip is ¢-1 inch thick, and of a width of the order of 30 inches, with a metal residence time in the mould of 2-8 sec. at an average withdrawal time between 10 and 60 inches/min. It may receive in-line heat treatment. The mould 5 is supported on a plate 18 which is mounted on ball bearings on a plate 19 to allow some sideways movement of the mould.

Title: Improvements in and relating to change speed gearing
IPC: F16H61/02
Filed: 1936-12-09
Abstract: 471,458. Controlling change - speed gearing. FLEISCHEL, G. Dec. 9, 1936, No. 33875. Convention date, Dec. 9, 1935. [Class 80 (ii)] A two-speed planetary train is operated by a sliding annular brake 12, Fig. 1, which is slid axially by servo means and as it slides, disengages a direct-driving clutch 9, 10 and thereafter remains in braking engagement with the freed clutch part 9 to effect a geared drive. That is, springs 16 tend to hold in the solid drive clutch 9, 10 which is disengaged by servo action and a sun gear 7 is held so that an annulus 2 drives the carrier 4 of planets 6 and a driven shaft 3 at reduced speed. The servo means may be an annular piston 36b, Fig. 11, or it may be a set of cylinders 36, Fig. 1, energized by oil pumped at 13 when a slide valve 38 is depressed. Forms of double coned and of multiple-plate clutching and braking surfaces are described. As shown in Fig. 10, any number of two-speed units A, B, C may be compounded in series, their control valves a, b, c being depressed selectively by solenoids such as 88 and a manual selector switch 91. In an automatic transmission for a vehicle shown in Fig. 11, an enginedriven governor 107 throws a lever 111 over to the right against a contact 114 every time a step-up in the speed of the driven shaft D is to be made. A resisting plunger 115 causes the changes up and down to be made at different speeds. This change of contact of the lever 111 turns a suitable motor 116 stepwise up or down to shift a switch arm 91 into four positions, bringing in the four speeds derived from two two-speed units B, C according to the invention. There are solenoids in the valve unit c of the gear unit C and a similar one in the valve unit of the gear unit B admitting oil pumped at 92 to the left of annular pistons 36b &c. The oil-return pipe 40 has a raised loop at 95. The gear unit A shown is for reversing and it is operated by a manual switch 119. The engine clutch 98 is brought in automatically by centrifugal weights 99, and a one-way clutch 103 allows the engine to be used as a brake. In a modified arrangement shown in Fig. 12, the engine clutch 126 is electromagnetic and is engaged by the engine-driven governor 107 throwing a switch lever 130 to engage a contact 132. The same governor throws the speed switch lever 111 over right for a stepped change up, and allows the lever 111 to return left for a change down. These steps are effected by angular displacements of the armature of an electric motor 116 which turns a shaft 77 with selector cams 79, 80 for depressing the hydraulic valves b, c of the two forward-driving units B, C. The reverse unit A is operated by a turn of the motor 116 effected by a manual switch 119.

Abstract: 367,467. Vacuum cleaners. GRIFFITHS, A. W., 50, Panton Road, Hoole, Chester. Aug. 12, 1931, No. 34137/30. [Class 8 (i).] - The nozzle of a vacuum cleaner is supported by wheels 20 within it, carrying gear wheels which drive the brush 23 ; the brush shaft is rotatably supported in arms 24 pivoted on the spindles of the wheels 20 and held in position by pins 26 passing through the ends of the nozzle and pressing the arms against abutments. The fan is driven from rear floor wheels 10 the spindle 9 of which has pinned to it a member 32, Fig. 7, recessed to receive rollers &c. which drive a rim 38 on a sleeve ; the further end of this sleeve is squared and carries a disc 41 attached by a spring to a worm wheel 8 driving a worm 7 on the fan shaft. Forward motion of the vacuum cleaner causes the rollers to engage and drive the rim and this motion is flexibly transmitted to the.wheel 8, a slight rotation of the sleeve taking place before a projection 38 on the sleeve rim is caused to engage a recess in the wheel. During backward motion the wheel and sleeve continue to rotate freely together. A handle 43 on one of the rear wheels enables the machine to be driven when stationary. The dust bag may then be curved around and under the fan casing and clipped to it.

Patent GB-1019726-A (GB)
Title: Improved method of making a fused multitube glass structure
IPC: C03B23/207
Filed: 1964-08-24
Abstract: <PICT:1019726/C1/1> A fused multitube glass structure 20 is made by assembling a multiplicity of glass tubes 26 in side-by-side relationship with each other in a bundle, heating the bundle to fusion temperature such that the glass tubes are simultaneously and individually expanded whilst the bundle as a whole is constrained against appreciable expansion to cause the tubes to fuse together along their entire lengths, the formed structure then being cooled. In a preferred method the ends of the individual tubes are sealed off at room temperature (68 DEG  F.) to entrap air, the air causing the tubes to expand when heated.  The bundle of tubes is placed in a mould 44, formed from four dismantleable sides 46 and end blocks and having a non-stick gold foil or asbestos paper lining, and the assembly placed in a furnace (heated electrically or by gas). Upon expansion the tubes, being constrained by the mould, completely fill the interstices between them to produce a structure having a number of uniform parallel end-to-end passageways.  The ends of the structure are usually removed.  For structures having fine bores individual tubes may first be drawn down before fusing, or a fused structure may be drawn down and then refused in a bundle of multitubes to form a further structure.  In alternative embodiments the tubes may be sealed with thermosetting resins, or may be sealed at very cold temperatures; the tubes can also be filled with solid or liquid CO2, or water.  To aid the formation, vacuum may be applied to the moulds during fusing, whilst compressed air may simultaneously be blown into the tubes.  For specific purposes the tubes used may have an inner coating of a material for producing, say, secondary electron multiplication.

Abstract: 492,572. Cables ; feeding washers from stacks. STANDARD TELEPHONES & CABLES, Ltd., NUNN, D., and SLADE, W. C. Dec. 14, 1937, No. 34576. Addition to 458,772. [Class 36] [Also in Group II] Spacing washers are supplied to the machine described in the parent Specification from a supply magazine comprising a series of stacks which come into operative position automatically as the preceding stack is exhausted. The stacks may be arranged linearly or, as shown, circularly. In the Figure, guides A are mounted between plates B, C ; fins 4, projecting through apertures in the guides, coact with the slots in the washers to orientate the washers, with recesses 8 in apertures 6 in the plate C to prevent rotation of the guides relative to the plate, and with latches 11 on the plate B whereby the guides may be locked-in position or readily removed. A follower 12, placed on the stack of washers, comprises a pin 13 projecting through a slot 29 in each guide. Washers pass through an aperture 15 in a plate 14 on which the guides rest to a guide 2, which is kept full, whence they are fed singly to the cable-making machine. As a stack becomes empty, the pin 13 contacts a switch 18, energizing a magnet 20 to withdraw a lever 17 from one of the apertures 6 ; the lever 17 operates a switch 21 to start a motor 22 to rotate the magazine : this causes release of the switch 18, return of the lever 17 and release of the switch 21 ; rotation of the supply magazine continues, however, due to the spring 25 and the action of the lever 17 on the sloping part of the aperture 6 until the lever 17 finally fully enters the aperture. The machine is stopped, in the event of an empty stack, by contact of the pin 13 with a switch 27 ; a sensing device may also be provided to stop the feed of the central conductor in the event of a missing washer. Two magazines with guides at 180‹, or two identical magazines, one of which has a helical feed guide 2, or two identical magazines having respectively front and rear feeds, or a single magazine having a double feed may be used to alternate the direction of the washer slots. When the guides are arranged linearly, two rows may be provided. Instead of a gravity feed from a vertical machine, a spring feed from a horizontal machine may be utilized.

Abstract: 991,525. Frequency-dividers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 2, 1963 [Sept. 5, 1962], No. 34596/63. Heading G4A. Means for dividing a standard frequency by a variable integral number comprises a differentiating circuit 23 and a first cascade counter 25 which produces output pulses from each stage as it changes to 1, the resulting pulses being thereby spaced and of different frequencies. These pulses are applied through selectively operated switches S0-S13 and a lead 26 to a second cascade counter 27 to produce a square wave at its output 29. Phase-error is reduced with increase in the number of stages. Phase-error is further reduced by a further counter 31 with the same number of stages as 27 which resets 27 each time the counter 31 restores to zero, so obviating failure of any stage in 27. The counter 31 may also control a programming counter 30 which can change the settings of switches S0-S13 at each step. The switches may be replaced by AND gates. Fig. 4 shows an arrangement for producing an output at 42 phase-displaced from that at 29 by an angle # set up in binary form flip-flops FF1<SP>11</SP>- FF9<SP>11</SP>. The conditions on unit 35 comprising of these flip-flops are compared at K1-K9 with those of FF1<SP>1</SP>-FF9<SP>1</SP> of counter 27. When K1-K8 show equality output circuit 40 is switched to one stable condition. When K1-K9 show equality output circuit 40 is reversed. Unit 35 may be a reversible counter. The instantaneous phase displacement between two output signals can be read from unit 35.
