Title: Improvements in or relating to dispersions
Inventor: CRESWELL GEORGE TONSON
IPC: C08F289/00
Filed: 1964-01-23
Abstract: An aqueous dispersion comprises an adduct, prepared by reacting in the presence of a free radical initiator, the anhydride of an unsaturated dicarboxylic acid, e.g. maleic anhydride, with a hydrocarbon resin prepared by the polymerization of a mixture of dienes, and either sufficient alkali metal hydroxide to neutralize or substantially neutralize the adduct or an anionic emulsifier or both. The hydrocarbon resin is obtained by polymerizing a monomer mixture consisting of or comprising dienes such as "probenzene" fraction of steam cracked petroleum, with a Friedel Crafts catalyst for example, boron trifluoride.  Of a number of free radical initiators listed, ditertbutyl peroxide is exemplified.  Ionic emulsifiers used are sodium rosinate or a mixture of tertiary aliphatic acids plus sodium hydroxide; others are also listed.  The dispersions, with the addition of ammoniacal casein solution and alum are used for the internal sizing of paper.ALSO:A dispersion used with the addition of ammoniacal case in solution and alum for the internal sizing of paper comprises an adduct, prepared by reacting in the presence of a free radical initiator, the anhydride of an unsaturated dicarboxylic acid for example, maleic anhydride, with a hydrocarbon resin prepared by the polymerization of a mixture of dienes and either sufficient alkali metal hydroxide to neutralize or substantially neutralize the adduct or an anionic emulsifier or both.

Abstract: 293,064. Dawson, F. G. T. Feb. 2, 1927. Planes, arrangement of.-An aircraft having similarly rotating propellers c, d not on the centre line, has those rear fins e, f that lie in the slipstreams from these propellers arranged to converge forwardly towards a point on one side of the centre line of the machine and in front of the propellers. If the fins are in the upper halves of the slip streams the fins converge towards that side of the machine to which the propeller blades move in the lower halves of their revolution. Where engines are used above and below the centre line of the machine the convergence of the elevators and tail planes is similarly determined. The distance of the line of convergence in front of the propellers varies with the distance of the fins and propellers from the centre line.

Title: An electric smelter for producing porcelain enamel frit
IPC: C03B5/027
Filed: 1952-02-06
Abstract: 704,713. Electrode furnace for porcelain enamel. THORNTON, A. A. (Ferro Enamel Corporation). Feb. 6, 1952, No. 3137/52. Class 39 (3) A smelter for porcelain enamel frit in which the constituents are heated bv current therethrough comprises a refractory-lined rectangular vault having its bottom 9 stepped down longitudinally from an end wall 4 to a low rectangular communication passage 11, where the molten enamel passes from the melting chamber under a vertical wall 5 into a lining chamber 19, whence the enamel frit passes over a weir 28 in the end wall to pass through a vertical discharge opening 30. The charging opening 18 in the end wall 4, the passage 11 and the discharge weir 28 are axially aligned along the line of flow of material. Pairs of electrodes are arranged on opposite sides of the axial line, the first pair A being adjacent the charging opening 18, the second pair B arranged downstream therefrom and more widely spaced in the melting chamber. A third pair of electrodes C is arranged further downstream and adjacent the passage 11 and a fourth pair of electrodes D is arranged adjacent the weir 28. The furnace is roofed and the partition wall 5 has an upper aperture 42 through which hot gas passes from the fining chamber to the melting chamber, whence it is discharged through a roof chimney 17, preferably under reduced pressure. The electrodes A, B for melting are of material lower in the electromotive series than the materials present in the batch as oxides. Thus in the presence of zirconium oxide, the electrodes are of molybdenum, but with the oxides of cobalt or nickel, graphite electrodes may be used. Inclined molybdenum plate electrodes A, B are supported by brackets 33 on rods 31 passing through the furnace walls. The rods 31 are carried externally by an angular bracket 35 pivoted at 37 on a bracket 38 on the wall, so that the transverse distance between the electrodes may be adjusted. The lower edges of door openings 39 have recesses in which a block is placed over the rod, allowing vertical adjustment of the electrodes A, B. The smelter may be emptied through a discharge in the side wall below the bridge 5. Specification 683,701 is referred to.

Title: Improvements in or relating to material handling systems
IPC: B66B17/26
Filed: 1958-01-31
Abstract: 880,864. Delivering materials to skip hoists. RHYMNEY ENGINEERING CO. Ltd., and DAVIDSON, G. W. Jan. 30, 1959 [Jan. 31, 1958], No. 3331/58. Classes 78 (1) and 78 (4). Material is stored temporarily, e.g. before delivery to or from a skip hoist in a mine, on a rotating turn-table 28. As illustrated, the turn-table receives coal from a tippler 26 through a shoot 27 and its rotation carries the material to a plough 34 which sweeps the material through either of two shoots 38, 39 feeding two skips 41 in a skip hoist. While the material is being delivered to the turn-table the plough 34 is allowed to rotate freely. The turntable makes two revolutions under these conditions, a plough 48 pushing the material delivered during the first revolution towards the middle of the table but being retracted during the second revolution. When the turn-table is to be unloaded a stop 46 or 47 is projected into the path of the plough to hold it in the delivery position. The turn-table is surrounded by a wall 29 provided with suitable gaps for loading and unloading and has an inner wall 30. A similar device may receive material from the skips at the surface and deliver it to conveyers. Air locks 42, 44 may be provided. The rotating plough illustrated may be replaced by a plough projected through a slot in the peripheral wall 29. Two spaced ploughs projecting radially by different amounts may divide the material into two streams for separate delivery. The ploughs may be driven directly, instead of by the material.

Abstract: 1,208,272. Embossing with foil. MASSON SEELEY & CO. Ltd. 22 April, 1968 [23 Jan., 1967], No. 3401/67. Heading B6J.  A marking press, in which a foil is interposed between a die and an article to be marked so that material is transferred from the foil to the surface of the article under pressure and optionally heat, comprises a support 9 for a die 22, Fig. 1, and a support 3 for the article 4 being marked, one of the supports, e.g. the support 9, being movable towards and away from the other. The drive for the press includes a reciprocable wedge 15, movement of which in one direction transmitting movement to a follower 17 to displace the latter in a direction perpendicular to the direction of movement of the wedge, and the follower causing the press to close, i.e. to move the support 9 towards the support 3. In operation, a constant pre-determined but adjustable force is applied to the wedge 15 by means of a pneumatic ram 18, or relief valve being provided in the system; the piston 19 of the ram can be connected directly to the wedge 15, or a toggle linkage can provide the transmission (not shown). Alternatively, the wedge could be driven by a motor, the system incorporating a slipping constant torque clutch which could be adjustable. The work support 3 is mounted on a vertically-adjustable table 2 to slide between operative and inoperative positions. A mask 5 is inserted between the support 3 and the foil which is fed between supply and take-up rolls 23 and 24. The die support 9 on withdrawal of the wedge 15 after marking is moved to inoperative position by return springs (13), Fig. 2 (not shown). Fine control of the force applied to the article 4 can be effected by means of fluid-operated jacks 20 which oppose the downwards force of wedge 15 on support 9 during the latter part of the closing movement of the press. The press can comprise a plurality of wedges each acting on a die support and individually driven. A heater box 27 may be interposed between the die support 9 and the die 22.
