Abstract: 1,221,909. Continuous casting; casting processes. STANDARD TELEPHONES & CABLES Ltd. 1 Oct., 1969, No. 48283/69. Heading B3F. [Also in Division F4] A crucible 52, Fig. 5, is formed by a ring of water-circulating tubes which are so spaced at a mould part l that molten material 54A cannot escape between them. A charge 54 of material is melted by an induction coil 50 to form the melt 54A on a starter plug 55 which is lowered for continuous casting. The tubes 1, Fig. 4, depend from an inlet portion of an annular coolant water header 5, and, to communicate with an outlet portion, either contain an inner water return tube, Fig. 1 (not shown), or are of the hairpin type, Fig. 3 (not shown). Further tapered-end tubes 41 containing return tubes 43, may be interposed between the tubes 1 at the upper part of the crucible. The tubes, which may be flattened, are made of gold, silver or copper, alloys of these metals or one of these coated with another of these. The starter plug 2 may likewise be made of these metals, in which case it is independently water-cooled, or of refractory material or of the metal being melted. The melt 54A is kept away from the tubes 1 by the magnetic fields induced by the induction heater. A quartz enclosure may surround the apparatus to allow casting of chromitun to proceed in an inert or a hydrogen atmosphere.

Title: Thermographic sheet
IPC: C09K5/00
Filed: 1971-10-19
Abstract: 1376611 Temperature indicating J TRICOIRE 19 Oct 1971 [20 Oct 1970] 48585/71 Heading G1D [Also in Divisions H3-5] A thermographic sheet comprises a layer 12 including temperature sensitive cholesteric liquid  crystal material and a parallel layer 11 formed to have a higher thermal conductivity in the direction of arrows 15 than laterally in the layer, so that the resolution of thermal images provided e.g. at a support layer 10 is not decreased by thermal diffusion. The layer 11 is produced from a latex, e.g. of a styrene-butadiene copolymer, either by heat reticulation of a single layer thereof, or by sequential deposition of a plurality of latex paint layers less than 50Á thick, for example by spraying. The layer 12 may comprise gelatine encapsulated liquid crystal material dispersed in a latex. The support layer 10, preferably a good heat conductor, may be of polyethylene glycol terephthalate, inter alia, and may be disposed between layers 11 and 12, Fig.2 (not shown). Alternatively the layers 10 and 11 may be identical and/or the liquid crystal material may be dispersed in a combined heat sensitive and heat guiding layer 11. The thermographic sheet may be mounted in a rigid or flexible frame, which itself may have provision for being mounted at one end of an arm, a camera being adjustably mounted at the other end of the arm for recording purposes, Fig.5 (not shown). In a further embodiment, Fig.7 (not shown) the sheet is flexible and is secured at its edge to a rigid transparent plate so that by inflation the sheet may be applied to shaped surfaces and observed through the rigid plate. In other variants, the sheet may be mounted on various types of medical instruments, and layers 12 including different cholesteric materials may be laterally juxtaposed ona common layer 11, to cover a wider temperature measuring range.

Title: Improvements in or relating to Suction Grip Devices
Inventor: CALLIGARO GIUSEPPE
IPC: F16B47/00
Filed: 1968-10-15
Abstract: 1,193,899. Suction grip fastenings. G. CALLIGARO. 15 Oct., 1968 [6 March, 1968], No. 48929/68. Heading E2A. A suction grip device comprises a flexible resilient membrane 1 supported along its outer periphery by a rigid cup shaped member 3 having a central aperture through which a stem 4 secured centrally to the membrane passes, an external tubular extension 6 provided on the cup shaped member and provided externally with a radial flange 10, a push button 5 slidable axially within said tubular extension and attached to said stem for effecting movement of the membrane away from the cup shaped member and a spring 7 housed in the tubular extension and interposed between an outer surface of the cup shaped member and the push button to urge the latter outwardly and draw the membrane towards the cup-shaped member. The flange can have a plurality of equi-angularly spaced apart pairs of hooks the arrangement enabling at least two of the hooks to be always available for hanging articles thereon independently of the angular position of the flange about its axis, alternatively the flange is circumferentially continuous and is intended for use with a plate formed with a keyhole shaped hole the plate being incorporated in any desired article such as a box, a roll holder or a towel holder. The external circumferential surface of the push button 5 is provided with an inner portion 14 of a colour contrasting with the remaining outer portion of the push button; when the device is gripping normally the portion 14 is disposed wholly within the bore of the tubular extension; a partial release of the vacuum allows the spring 7 to move the push button 5 to expose part of the inner portion 14 of the push button and the contrasting colour provides a readily discernable warning.

Title: Improvements in or relating to antennae
Inventor: TURRIN RICHARD HERBERT
IPC: H01Q5/45
Filed: 1964-12-03
Abstract: 1,080,546. Aerials. WESTERN ELECTRIC CO. Inc. Dec. 3, 1964 [Dec. 5, 1963], No. 49148/64. Heading H4A. [Also in Division H1] The effective area of a radiating aperture provided in a waveguide operating at two frequencies is decreased at the higher frequency by means which causes wave energy at that frequency only to be concentrated in the centre region of the aperture, whereby the radiation patterns for both frequencies are made substantially the same. As described, a circular air-filled waveguide 11 is fed from a source 13 at one end and radiates energy at the other end, in which end a cylindrical rod 10 made, for example, of material with dielectric constant two or more is held coaxially by an annular plug made of material with dielectric constant nearly one. The rod 10 is tapered at its end inside the waveguide and is squared-off at the other end, which protrudes by a small amount from the aperture. At both the lower and the higher frequencies transmission of energy to the radiating aperture takes place in the TE 11  mode, Fig. 2A (not shown), but at the higher frequency it also takes place in the TM 11  mode, Fig. 2B (not shown), causing a concentration of energy of that frequency at the centre of the aperture, Fig. 2c (not shown). It is stated that the phase and magnitude of the TM 11  energy may be controlled by adjustment of the dimensions of the rod 10 and its position within the waveguide 11, and that in consequence substantially equal radiation patterns at both frequencies may be obtained (Fig. 4, not shown). The dimensions of the waveguide are chosen so that the cutoff frequency for transmission in the TM 11  mode is greater than the lower frequency of operation. A paraboloidal reflector 70 or a lens may be used in conjunction with the radiating aperture. One frequency may be used for reception and the other for transmission, as in a communications system link, and the two may be polarized linearly and orthogonally to reduce interaction.

Abstract: 1364502 Foundry moulding machines; flasks SHERWIN-WILLIAMS CO 22 Oct 1971 49225/71 Heading B3F A foundry moulding machine has a pivot column 32, at one side of the column 32, a moulding station 30 for forming cope and drag moulds, at the other side of the column 32, opposed to the moulding station 30, a mould closing station 31 for uniting drag and cope moulds and stripping them from their flasks C, D, a pivoting frame 48 holding drag D and cope C flasks and a pattern shuttle 92 for presenting cope and drag patterns alternately to the moulding station 30. In operation, an inverted drag flask D is held in the pivoting frame 48 within the moulding station 30 and a moulding table 100 is lifted to entrain and lift a drag pattern 93 from a pattern shuttle 92 into the drag flask D. A sand shoot (not shown) is pivoted to a position between a sand hopper 40 and the drag flask D and the flask is sand-filled. Afterwards the sand shoot is removed with concomitant positioning of a press-head 78 above the drag flask D and the table 100 further lifted to press the drag mould so-formed. The table 100 may be jolted both during flask-filling and pressing. The table 100 is retracted and the frame 48 pivoted to bring cope flask C into the moulding station 30, to invert the drag flask D and place it in the closing station 31. The cope mould is similarly moulded while the drag flask is stripped. Flasks, turning, clamping, guiding and stripping.-The drag flask D (Figs. 11, 12) is provided with trunnions 122, 123, one of which 123 has a keyway for engagement with a flask-turning device 121. The device 121 on frame 48 is rotated by means of a gearing (133, 134, not shown) as the frame 48 is pivoted on the column 32. Trunnion stops 227, 228 are provided on the frame 48. At the closing station 31 the drag flask D is lifted by diagonally opposite support rods 176, (178) engaging pads 231 until stripper rods 46 engage taper rods 205 at the other diagonal corners of the flask D. Further movement upwardly involves downward movement of the taper rods 205 in taper bushings 212 as biasing springs 216 are compressed. In the flask D rubber spacer blocks 220 expand, taking up play between the taper rods 205 and taper bushings 212 and thereby allowing the drag flask D to expand and to release a drag mould 240 on to a table 141. After placing cores into the drag mould 240, the drag flask is pivoted back to the moulding station and a completed cope mould in its flask C brought above the drag mould 240. The mould 240, is lifted together with tables 141, 140 and rods 175 to 178 to force the cope mould against a stripper plate 45 and to lift the cope flask C from the cope mould by means of the rods 175 to 178, at the same time uniting the cope and drag mould parts.

Abstract: 1405020 Mixing an aerosol with a liquid BEKAERT SA NV 30 Oct 1972 [29 Oct 1971] 49976/72 Heading B1C In a method and apparatus for mixing a first liquid with a smaller quantity of a lower viscosity liquid additive, the first liquid is introduced into an enclosed mixing chamber e.g. duct 51 in mixing head 1, Figs 1, 2, and the additive is introduced into the first liquid together with a pressurised gas, in the form of an aerosol. In the apparatus, the gas is introduced by means of an inlet duct 32, 60 associated with means such as atomising valves 34-39 for introducing the liquid additive.  In the particular method and apparatus, the gas in supply reservoir 30 is compressed air and also pressurises additive reservoirs 23, 24 containing the optional additives Freon (registered trade mark) and water, and cleaning solvent reservoir 40 which flushes out the mixing head after use. The first liquid is a combination of two components, separately agitated heated and stored before use in reservoirs 2, 3. These components such as a polyisocyanate and a polyhydroxyl compound, are fed to mixing head inlet valves 14, 15 along lines 7, 8 and may be recycled along lines 16, 17. The valves 14, 15 are adjustable needle valves, Fig 4, which may be switched on and off by compressed air in ducts 73 and 74, 83 and 84 which acts on flexible diaphragms 71, 72. After introduction of the first liquid, adjustable needle valve 33, Figs 1, 2 is opened by solenoid operated valve 63 controlling the flow of pressurised air to needle piston 61 and the compressed air flows from duct 60 into mixing duct. 51 to create turbulence in the liquids therein. One or more of valves 34-39 spaced around the axis of duct 60 is opened and the liquid additive forced in forms an aerosol with the air. After mixing-aided by impellers 53, 56-the mixture is ejected through duct 52 and valves 14, 15 34-39 are closed. Pressurised air from line 32 then cleans duct 51. Flushing solvent from reservoir 40 may then be introduced. The valves 34-39 may be of different flow rates but introduce additive at the same pressure so that used singly or in combination they can provide a selectively variable flow of additive and hence mixtures of variable proportions of constituents.
