Title: Sand cooler
IPC: B22C5/08
Filed: 1967-03-21
Abstract: 1,121,258. Cooling sand. NEWAYGO ENG. CO. 21 March, 1967 [30 March, 1966], No. 13148/67. Heading F4U. Sand to be cooled is fed through a hopper 30 having outlets 32 at its lower edge on to the imperforate centre of an otherwise perforated rotating disc 36, the sand being cooled and kept in suspension while moving radially outwardly across the disc by air from a plenum chamber 90. Sets 20, 20a of beaters are arranged in the sand which is removed from the periphery of the disc by an adjustable plough (Fig. 2, not shown) arranged in an opening in the peripheral wall 40 of the device. Diametrically opposed air compressors 92, 94 supply the annular plenum chamber, the height of the latter decreasing from a maximum at the location of each compressor to a minimum at the location midway between the compressors. Water may be sprayed into the sand to assist in cooling and the device preferably has a cover formed with air outlets (Fig. 1, not shown). The pitch of the paddles in sets 20, 20a is such that the inner paddle blades tend to move the sand radially outwardly while the outer blades tend to move the sand in the reverse direction to prevent build-up of sand on the periphery of the disc.

Title: Improved method of providing vacuum vessels such as electric discharge tubes with a getter-layer
IPC: H01J7/18
Filed: 1946-05-01
Abstract: 611,469. Obtaining high vacua. PHILIPSLAMPS, Ltd. May 1; 1946, No. 13165. Convention date, May 4, 1945. [Class 8 (i)] Also in Group XL (a)] In the manufacture of a vacuum vessel with a getter layer, a metal combining with gas is quickly volatilized, and deposited on an artificially-cooled surface, which has previously been coated with a carbon layer. The volatilization maybe effected in the presence of a gas such as nitrogen or carbonic gas, which may be released during volatilization and subsequently bound'during the deposition of the metal, or may take place in the presence of a rare gas, which is then pumped. off. The surface, such as the wall of the vessel, is preferably cooled by liquid air or a freezing mixture, and the getter metal is preferably constituted by barium containing a certain amount of nitrogen, for example barium nitride. The invention is applicable to, for example, electric discharge devices and hollow resonators.
Patent GB-696322-A (GB)
Title: Improvements in or relating to adhesive compositions
IPC: C09J109/04
Filed: 1951-06-04
Abstract: An adhesive composition comprises an aqueous dispersion of a copolymer of a butadiene-1,3 hydrocarbon and an acrylic nitrile and 2 to 50 per cent by weight of the copolymer of a rosin alcohol, the copolymer having a molecular weight below 100,000 and a Mooney viscosity, determined by means of the Mooney viscosimeter using the 1.5-inch rotor after 4 minutes at 212 DEG  F., of between 10 and 35. Suitable rosin alcohols are dehydroabietyl alcohol, dihydroabietyl alcohol, tetrahydroabietyl alcohol and mixtures of these.  Specified butadiene hydrocarbons are butadiene-1,3, isoprene and 2,3-dimethyl butadiene-1,3, and the nitriles include acrylonitrile, chloroacrylonitrile, methacrylonitrile and ethacrylonitrile.  The copolymers are preferably prepared in aqueous emulsion from a mixture comprizing 30-80 per cent butadiene and 20-70 per cent acrylonitrile. Minor amounts of other polymerizable materials such as methyl acrylate and methacrylate, styrene, acrylic acid, vinyl benzoate and vinyl pyridine, may be included.  The soft, low molecular weight copolymers are obtained by using large amounts of sulphur-containing modifiers or by terminating the polymerization at an early stage. The rosin alcohol is preferably added in the form of an aqueous emulsion for the production of which emulsifying agents, such as fatty acid soaps, rosin acid, hydrogenated rosin acid, disproportionated rosin acid soaps, hymolal sulphates and alkaryl sulphonates, are used.  The copolymer latex is preferably concentrated to contain at least 35 per cent copolymer and age-resistors &c. are added before adding a concentrated emulsion (25-60 per cent) of the rosin alcohol, along with more emulsifying agent.  The mixture is stirred until homogeneous and may be applied to various surfaces and dried and the coated surface may be sealed to a similarly coated surface by pressure and/or heat (see Group VIII). Other materials such as natural or synthetic rubber and resin latices, waxes, fillers, stabilizers and thickeners may be added to the compositions.

Title: Improvements in or relating to sound reproducers or transmitters
IPC: H04R7/18
Filed: 1929-07-01
Abstract: 337,836. Matthew, E. M. July 1, 1929. Divided on 331,828. Magnetic instruments.- A moving coil sound transmitter or reproducer, such as a loud-speaker, is associated with switchgear and surge preventing devices which protect the moving coil and field exciting windings when these windings are being brought into or out of operation. The switchgear may either be mounted on the loud-speaker or employed as a remote control. On switching on the moving coil circuit a variable resistance of the order of one megohm is introduced into the circuit and is gradually cut out until it is inoperative when the circuit is completed. An anti-sparking or buffer resist. ance is also connected in parallel with the field exciting circuit immediately prior to and during connection of this circuit to the source of supply, the resistance being inoperative when the circuit has been completed. The switch is so arranged that the moving coil circuit is closed before the field exciting circuit, the latter being broken before the moving coil circuit. If desired, the. variable resistance may be completely traversed before the field buffer resistance is connected. Figs. 8 and 9 show a construction of switch in which the body B is provided with a recess D<1> for housing the moving coil variable resistance which contacts with a number of metallic segments S<1> - - S<5> adapted to be traversed by a spring loaded metallic plunger or flexible strip P connected to one metallic pivot G of the switch barrel E. The segment S<5> is connected to a terminal T<1> to which the moving coil M is connected whilst the pivot G is connected to a terminal T<2>. If desired, the segments may be dispensed with and the resistance itself traversed by the arm P. A metallic segment H connected to the metallic pivot K is fixed to or moulded with the barrel E and traverses over spring- loaded contacts L, N. The contact N is connected to a terminal T<4> which is connected to the field winding F and the pivot K is connected to a terminal T<5>. The buffer resistance is housed in a recess D<2> in the body B and has one of its ends connected to contact L and the other to a terminal T<6>. The pivot G may be located in the body B by a metallic bushing and the pivot K by a similar bushing in the switch cover (not shown), rotation of the barrel E being limited by pins fixed to one or both pivots and working in recesses in the body and cover.
