Patent GB-662634-A (GB)
Title: Improvements in or relating to the process of smelting of metal and a furnace therefor
IPC: C22B9/00
Filed: 1947-06-27
Abstract: 662,634. Melting and refining metals. WEIL, W. M. June 27, 1947. [July 12, 1946] No. 17014/47. Class, 82(i). [Also in Groups XI and XII] Metals such as aluminium are melted and refined in a reverberatory furnace (see Group XII), which in one form, Figs. 2 and 3, comprises a main heating chamber, which normally contains a pool of molten metal B, and an auxiliary open chamber having a hearth 18 arranged at substantially the same level as the main hearth 1 and divided by a partition 40 into two compartments adapted to contain pools of metal C and A and communicating with the main chamber through passages 20 and 21 respectively. The passage 21 is provided with a vertically-movable door 22 which is normally so positioned as to prevent flow of slag from the surface of the pool A into the main chamber. Molten metal may be withdrawn from the pool C through vertical passages 23, 24 and caused to flow upwardly through a central passage 26 by means of an electromagnetic induction pump, (see Group XI), which also effects heating of the metal in the passages. The passage 26 communicates with a pipe 37 through which a stream of metal may be directed into the pool A over a lip 38 formed on the partition 40. In operation, solid metal to be melted is charged into the pool A adjacent the partition and is engulfed by or mixed with molten metal fed through the pipe 37, fluxing or refining agents being added to the resulting pasty mass. Charging is then discontinued for a period sufficient to allow liquefaction of the mass, the impurities rising to the surface being skimmed off and the refined material flowing into the heating chamber where it may be tapped off. Molten solid metal may then be charged and the process repeated. In a second form, Fig. 7 suitable for a continuous process, metal is withdrawn from a pool D in the auxiliary chamber by an electrically-driven pump 76 and supplied to a manifold 82 having lateral branches 83 and 84, controlled by gate valves 85 and 86, from which the metal may be discharged tangentially into a hopper 72, 73 and into the pool E respectively. Solid metal to be melted together with fluxing and refining agents is fed continuously into the hopper and becomes mixed with the molten metal due to the whirling motion induced by the discharge from the branch 83, the resulting pasty mass passing through opening 75 into the pool E where it is liquefied by the stream of metal from the branch 84. At this stage the metal is puddled and the slag skimmed off, the refined metal passing into the main chamber through the passage 22. Further refining agents may be introduced through the branch 84. Specifications 542,347 and 632,947, [Group Xi], are referred to.

Title: Improved process for the recovery of light-alloy scrap
IPC: C22B21/00
Filed: 1940-11-29
Abstract: 570,166. Working aluminium &c. alloy scrap. GROOM, E. J. Nov. 29, 1940, No. 17073. [Class 83 (iv)] [Also in Group II] Aluminium- or magnesium-base alloy scrap is recovered by freeing from cutting oil, free iron &c., comminuting and subjecting to pressure in a die, hot or cold. This avoid's the formation of undesirable combinations of alloying materials. Aluminium scrap may be comminuted so that 80 per cent will pass a 200-240 I.M.M. sieve and pressed, hot, e.g. at 350-450‹ C., or cold, in a die at 5-80 tons per sq. in. Magnesium scrap may be comminuted to pass a 200 I.M.M. sieve and subjected to a pressure of 10-30 tons at 250-300‹ C. The scrap is preferably comminuted in a ball mill to produce angular grains. If the powder is made by stamping it is then treated by two air-screw streams in a chamber to convert the lamellar grains to a spherical form. The powder may be adjusted to desired analysis by adding selected powdered scrap and may be heated by heating the die, by passing an electric current through the mass, or by induction. The die.may have the shape of the article required or a pressed block may be machined, finished pressed, or extruded. In this case the first pressing is at a low pressure, e.g. 5-6 tons per sq. in.

Title: Automatic machine for moulding, from dough, the shells or cases required in the manufacture of meat pies, fruit tarts and the like
IPC: A21C3/00
Filed: 1946-06-11
Abstract: 612,934. Pie-moulding machines. GLEDHILL, H., and MILLER, G. R. M. June 11, 1946. No. 17335. [Class 87 (ii)] To form a pie shell, dough is fed by means of an intermittently rotating worm g, Fig. 2, from a hopper h into a hollow male die band extruded through slots b<1>, Fig. 3 (the left part of Fig. 3 shows the dies open and the right part shows them closed), into the space between the die and a co-operating female die c. The female die c is then lifted, by a rod n acting on a bar m, and the upper part of the die c lifts a bar i<3>, which lifts a sleeve i having parts i<@> to close the slots b<1>. This upward movement also brings passages k in the die b and slots i<5> into alignment to allow excess dough to return to the inside of the die b. Further upward movement seals the passage k and causes the pie shell to be moulded between the dies. The bar m is then lowered to lower the die c, which has a loose bottom o that is stopped by a rod p when it abuts against a fixed bar q ; the die is further lowered to expose the moulded shell, which is pushed on to a table r or a conveyor. The return downward movement of the sleeve i is effected by springs j. The dies b, c may be electrically heated. The rod n may be actuated bv crank or cam mechanism and the intermittent rotation of the worm may be synchronized with the opening and closing of the slots b<1>.

Title: Improvements in or relating to directional aerial systems for use in wireless telegraphy and telephony
IPC: H01Q19/10
Filed: 1925-07-06
Abstract: 259,294. Franklin, C. S. July 6, 1925. Directive signalling; aerials; coupling oscillating and radiating circuits.-In a directional system, particularly suitable for short-wave signalling, a series of aerial units A1 - - A4, preferably of the type described in Specifications 242,342, are combined with reflecting-units R1 - - R4 so as to produce or receive a vertically-directed beam. An inclined reflecting-system IR, arranged at a higher level and preferably of larger area than the main aerial, comprises a number of insulated tuned units. These are arranged to reflect the beam into a plane substantially horizontal and parallel with the wires A, Fig. 1, or, as in Fig. 2, into an horizontal plane at right-angles to the wires A. In Fig. 1 the reflected beam is planepolarized in the vertical sense, whilst in Fig. 2 it is horizontally polarized. As the unidirectional network comprising the wires A and R is located near to the ground, the means for energizing the system through the feeders F and transformers T is simplified. Further, since the reflecting network IR is energized totally by re-radiation from the main aerial, no connecting feeders are necessary, and the network can therefore be located at a considerable elevation above the ground. The directional aerial A and its associated reflector may be replaced by a known arrangement comprising an aerial arranged at the focus of a large parabolic reflector.

Title: Improvements in or relating to the mechanical recording of sound or other oscillations
IPC: G11B11/00
Filed: 1935-06-17
Abstract: 445,658. Recording sound &c. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. June 17, 1935, No. 17384. Convention date, July 19, 1934. [Class 40 (ii)] Relates to apparatus for mechanically recording sound or like vibrations on a film by means of a recording member vibrating substantially normally to the film surface, and particularly to devices in which a V-shaped chisel operates on a celluloid or like film having a transparent layer such as gelatine and an opaque covering layer. According to the invention, the recording surface of the film is pressed against a support, adjacent to the point of recording, by a pressing member which, as well as the support, has a plane bearing surface, the pressing member being movable substantially normally to the bearing surface. Defects in recording usually caused by variations in the thickness of the film are thus obviated, and certain disadvantages arising from the use of a curved support are avoided. In the construction shown, the film, not shown, moves along a support 8, being pressed against the recording point 18 by a member 9. This is provided with a flexible metal strip 11, which is attached to a strap 10 screwed to the support 8. The pressing member 9, which has a plane bearing surface 20 and side strips 21, Fig. 7, is forced against the film by means of a micrometer screw 15, movable in a nut, not shown, and acting through a plate 14 and a rubber damping sheet 19. The bearing surface of the support 8 may be grooved, to provide air lubrication, and the film may be lubricated with grease or oil. Preferably, however, the support and /or the pressing member are made of an oily wood such as palm wood or pock-wood, to render supplementary lubrication unnecessary.

IPC: H04N5/225
Filed: 1956-06-06
Abstract: 858,704. Optical-projection apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 6, 1957 [June 6, 1956], No. 17411/56. Class 97(1) In an arrangement for effecting change over between two optical projectors, different colour light filters are respectively provided in the paths of light from said projectors and a dichroic mirror for reflecting one and transmitting the other of said colours is disposed in the paths of light from both of said projectors subsequently to said filters, the arrangement being such that the path of light from one of said projectors when reflected by said mirror is substantially coincident with the path of light from the other of said projectors when transmitted by said mirror, the arrangement also comprising means whereby light from each of said projectors can be prevented from reaching or allowed to reach an image-receiving surface for said projected light. The form shown comprises a projector 2 with a green filter 6, the output of which may be intercepted by a red-transmitting, green-reflecting dichroic mirror 11 and a projector 3 with a red filter 7, the output of which may be intercepted by a red-reflecting, green-transmitting dichroic mirror 10. The projector 1 has alternative filters 8 (red) and 9 (green). Both dichroic mirrors are removable. To permit change over between projectors 1 and 2 the filter 8 is inserted in projector 1 and the mirror 11 placed in position. The combined light beam is concentrated by a field lens 5 into a television camera 4. To permit change over between projectors 1 and 3 the filter 9 is inserted in projector 1 and the mirror 10 placed in position. To permit change over between projectors 2 and 3 both mirrors are placed in position. The devices for moving the filters 8 and 9 and the mirrors 10 and 11 may be coupled together. The actual change over in either case may be effected by dimmers acting on the lamps or neutral wedges or guillotine shutters acting on the light beams.

Title: Windscreen wiper
IPC: B60S1/06
Filed: 1940-12-07
Abstract: 543,635. Windscreen wipers. SLATTERY, M. S., and ROBERTSON, D. R. Dec. 7, 1940, No. 17428. [Class 138 (i)] A windscreen wiper, particularly for aircraft, is operated by the action of the wind on a streamlined or other vane 7 pivoted about an axis 6 extending at right-angles to the usual pivoted wiper arm 4. The movement of the vane is limited by stops 8, 9 on the wiper arm, and the movement of the wiper arm by stops 10, 12, which engage the leading end 11 of the vane and throw the vane over from one stop 9 to the other 8, or vice versa, and thus reverse the direction of motion of the wiper. The stop 12 is adjustable so that it can be set to engage the trailing end of the vane, and so to park the wiper. In a modified construction, the stops 10, 12 are dispensed with, and use is made of the gradual change in the angle of the vane, under the influence of the wind, as it moves across the screen, to cause reversal of movement of the wiper arm.
