Title: A device for Ladling Molten Metal from a Bath of the Metal
IPC: B22D17/30
Filed: 1966-07-13
Abstract: 1,154,214. Casting-machines. UBE INDUSTRIES Ltd. 13 July, 1966 [10 Aug., 1965], No. 31548/66. Heading B3F. [Also in Division B8] Measures of molten metal are conveyed from a holding or melting pan 3, e.g. to a pivotable funnel 29 over the inlet sleeve 30 of a die-casting machine, in a ladle 4 suspended from a pivot 8 on an arm 9, driven by an hydraulic motor 18 to swing to a pouring position B while the ladle is kept from tipping by a cable or chain 13, 14 passing around sprocket-wheels 7, 11 (or a rope or belt around pulleys) the latter wheel 11 being unrotatable and fixed to a bracket 12 pivoted on a shaft 22. With the arm 9 in position B, the ladle 4 is aligned with the pivot shaft 22 so that when a piston-and-cylinder 24, 27 pivots the bracket 12, Fig. 3 (not shown), the ladle 4 merely tips for pouring whilst the free arm-end with its sprocket-wheel 7 swings down around the ladle. The funnel 29 pivots to the position E shown, at the completion of pouring, to prevent extraneous matter falling into the inlet sleeve 30. If the arm 9 swings in and out of the melt pan 3 in a vertical plane the ladle conveys its full volume of metal but it may be swung in an inclined plane, determined by the position of the bracket 12, to convey smaller measures, although, to avoid spilling, it is swung over (to the pouring position B) in a vertical plane.

Title: Improvements in carburetters
IPC: F02M1/00
Filed: 1934-11-03
Abstract: 445,488. Spray carburetters. ELLIOTT, A. G., Darley Bene, Belper Road, Derby. Nov. 3, 1934, No. 31635. [Class 7 (iii)] In a carburetter having a suction piston which operates a trunk controlling the air passage way and carrying a fuel needle valve, fuel is supplied to one or more downtakes through a distributer disposed across the downtake, the supply being controlled by the needle valve, and a member carried by the suction piston passes into the downtake to form a choke for the distributer and moves along the axis of the downtake to maintain the air velocity past the distributer at about a predetermined value. In the form shown, a suction piston g opposite the air inlet h controls two downtakes d, d<1> between which is arranged in a casting b<3> a fuel supply device consisting of needle valves f, f<1> co-operating with seat members b, b and slidable in sleeves f<2>, f<3>in the casting. The needles are pinned to rods f<5>, f<6> adjustably mounted in a sleeve f<8> fixed in the suction piston g. The needle valves control respectively the fuel supply to distributer bars b<9>, b<10> disposed one across each downtake and each bar is bridged by a downward extension of the piston comprising two members j<2>, j<3> forming an inverted V. Apertures j<4> where the extensions join the piston ensure that the air passage is most restricted at the distributer bars. Engine suction is transmitted to the upper side of the piston g by pipes h2. At starting, additional fuel is supplied by lowering the valve seats b, b<1> by a lever l. In a modification, fuel is supplied to a single downtake through a downward extension of the distributer bar, the upper end of the extension forming the valve seat, and a manually controlled byepass provides additional fuel for starting.

Abstract: 1,237,499. Dyeable acrylonitrile copolymers. STAMICARBON N.V. 23 June, 1969 [25 June, 1968], No. 31639/69. Heading C3P. Dyeable acrylonitrile copolymers are prepared by polymerizing a monomer mixture containing (a) at least 35% by weight of acrylonitrile and (b) α-methylene-glutaric acid and/or a monohydrocarbyl or mono-(substituted hydrocarbyl) ester thereof, preferably in an amount of 0À1- 10% by weight. Where the mono-ester is used in (b), some corresponding di-ester may also be present. Preferred as mono-esters for (b) are C 1 -C 22  mono-alkyl esters; other suitable esters are the cyclopentyl, cyclohexyl, phenyl and benzyl esters. The hydrocarbyl group of the ester monomers may be substituted, for example, by halogen. The monomer mixture may include a further monomer component, e.g. methyl acrylate, methyl methacrylate, vinyl acetate, vinyl chloride, vinylidene chloride or styrene. Polymerization can be effected in bulk, in solution (e.g. in dimethyl formamide, dimethyl acetamide, dimethyl sulphoxide or aqueous zinc chloride), or in aqueous dispersion or emulsion, using initiators such as azoisobutyronitrile, lauroyl peroxide, hydrogen peroxide, di-(t-butyl- 4-cyclohexyl) percarbonate, cumene hydroperoxide, potassium persulphate/sodium metabisulphite (optionally with ferrous compounds), butyl lithium or U.V. radiation. In aqueous polymerizations the pH is preferably from 1À5 to 3À5. A chain transfer agent such as dodecyl mercaptan may be included in the polymerization reaction. The copolymers obtained can be used to form shaped objects such as filaments and may be admixed with additives such as heat- or U.V.-stabilizers, pigments, dyes, plasticizers, fillers and lubricants.

Title: Improvements in or relating to photographic cameras
IPC: G03B7/12
Filed: 1961-09-05
Abstract: 974,479. Photo-electric camera exposure control. CARL ZEISS-STIFTUNG, [trading as C. ZEISS [firm of]], and COMPUR-WERK G.m.b.H., [trading as COMPUR-WERK G.m.b.H. & CO.]. Sept. 5, 1961 [Dec. 19, 1960], No. 31837/61. Heading G2A. In a photographic camera fitted with a built-in photo-electric exposure meter, a feeler member sensing the position of the exposure meter needle, is coupled to a spring loaded diaphragm actuating mechanism by means comprising a follow-up shaft connected to the diaphragm mechanism and constructed so that it transmits torque yieldingly in the sense of rotation for cocking the diaphragm mechanism so as to limit the cocking torque transmittable to the diaphragm mechanism, but transmits torque rigidly in the opposite sense of rotation. In the embodiment shown, the coupling means of the invention comprises a sleeve 5 enclosing the end of a free moving follow up shaft 7, the two being resiliently coupled for clockwise rotation by a surrounding spring 8 having its ends fixed respectively to the sleeve and to the shaft, and rigidly coupled for anticlockwise rotation by sleeve extension 6a abutting shaft pin 9. The sleeve 6 is coupled, by way of a ratchet clutch 5 engaged for clockwise rotation, to a feeler member 2 biased by spring 3 to the bottom of the meter scale, and, by way of a one way clutch 20, locked during the diaphragm cocking process, to a cocking ring 16 biased anticlockwise by spring 16b. The one way clutch 20 Fig. 2 comprises two separate pinions 17a and 17b coupled by an intermediate loose sleeve 20 formed with a wing 20' engaging with pinion wings 17a<1> and 17b<1> for locked anticlockwise rotation, but allowing two free rotations of the pinion 17a in a clockwise direction. The follow-up shaft 7 is coupled to a stop ring 10 having an extension 10a bearing against a diaphragm opening projection 12 against the action of spring 13. In the diaphragm cocking process the cocking ring is rotated clockwise by pinion 15a until a catch 19 engages arm 16a. Sleeve 6 is rotated clockwise and causes the diaphragm to be fully opened, spring 8 coiling up to an extent depending on its strength relative to that of spring 13. The ratchet clutch 5 is released and the feeler member 2 swings to the bottom of the meter scale. On release of catch 19, cocking ring 16 rotates anticlockwise and spring 13 causes the feeler member 2, via the rigid coupling between pin 9, extension 6a and clutch 5, to abut the clamped meter needle 1 and so set the diaphragm. By means of the now slipping clutch 20 the cocking ring 16 continues to turn to activate the shutter release (not shown).

Abstract: 1,216,368. Control of A.C. motors; protective arrangements. ROTORK CONTROLS Ltd. 3 Oct., 1969 [4 July, 1968], No. 31851/68. Addition to 1,144,188. Headings H2J and H2K. The system of the parent Specification, in which a reversing starter in a motor-operated actuator cannot be energized unless the phase sequence of a polyphase supply is correct, is modified in that a contact 32 in the starter circuit 28 is now normally closed and is opened by energization of a relay 19 if the sequence is incorrect, and the two phases used for the supply to the starter circuit include the one used for the relay. Thus the relay is not energized under normal conditions, as it was in the parent case. Protection against the absence of one phase is still provided, by selecting the values of the components in the phase sequence detecting circuit 31. The starter circuit is now energized via a transformer 46 which, with resistor 15, may have tappings to accommodate various supply voltages.

An accumulator has an electrode 1 of silver which is wrapped in a viscose foil 3 and a second wrapper 4 of absorbent material such as paper or spun glass outside of which is a zinc electrode 5. An alkaline electrolyte such as a solution of caustic potash is absorbed in the wrappings and the whole maintained under a pressure of from 10 to 20 kg. per sq. dm. in a vessel 7. The elements are assembled as shown in Fig. 4, the plate 1 being first wrapped in several turns of thin sheets 3, 4 of the foil and paper over which a zinc sheet is placed having two limbs 5a, 5b. The assembly is then folded into U-shape, the two parts 5a, 5b of the zinc electrode being electrically connected together by a silver or copper plate 6a, as shown in Fig. 1. Terminal connections 2, 6 are taken from the upper ends of the electrodes. The electrodes and absorbent wrappings are placed in the vessel 7 in the dry state, the subsequent addition of the electrolyte causing the wrappings to swell and compress the elements. The vessel 7 is of sufficient strength to prevent deformation and may be made of metal coated or provided with a lining of alkali-resistant substance such as rubber or a resin. During the operation of the accumulator the wrapping 4 becomes impregnated with spongy zinc. When making a battery of cells connected in series each vessel 7 may contain two groups of elements joined in parallel and the whole may be contained in a frame 14, Fig. 6, having metal end-plates 15 which may be curved inwardly when the battery is new. A thin metal band 17 surrounds the frame. Specifications 680,793 and 682,165 are referred to.
