Title: Polymer compositions
Inventor: EVANS ARTHUR WALLACE
IPC: C08F2/44
Filed: 1961-08-03
Abstract: A process for the production of pigmented polymers comprises dry milling together a pigment and a composition of which at least the greater part is a polymerizable monomer, the amount of pigment being at least 1% by volume of said composition, and thereafter polymerizing the monomer.  Specified pigments are rutile and anatase, which may be coated with alumina, silica and/or titanium dioxide. Milling may be effected in the presence of dispersing agents, e.g. ethylene oxide condensates with fatty acids and alcohols, sodium hydrocarbon sulphonates, quaternary ammonium salts and alkyd resins, particularly oil modified alkyds. Specified monomers are vinyl acetate, acrylic and methacrylic esters, acrylonitrile, vinylidene chloride, styrene, butadiene and dialkyl maleates and fumarates. Polymerization may be effected in bulk, suspension or emulsion, e.g. in the presence of alkyl or hydroxyalkyl cellulose ethers, in the presence of peroxide and redox initiators and sequestertering agents. Plasticizers may be added before polymerization.  In examples, vinyl acetate is milled with a rutile pigment coated with alumina and titanium dioxide in the presence of (1) a linseed oil modified pentaerythritol alkyd resin and the product polymerized in aqueous emulsion in the presence of hydroxyethyl cellulose, polyethylene oxide, trisodium salt of ethylenediamine tetraacetic acid, sodium bicarbonate, ammonium persulphate, sodium metabisulphite, and with the addition of benzoyl peroxide, vinyl acetate and dibutyl phthalate, and (2) a linseed oil modified pentaerythritol alkyd resin and dibutyl phthalate, and the product polymerized in aqueous emulsion in the presence of hydroxyethyl cellulose, a condensate of ethylene oxide with a long chain fatty alcohol, ammonium persulphate and sodium formaldehyde sulphoxylate, and with the addition of benzoyl peroxide, vinyl acetate and dibutyl phthalate.  The products may be used in emulsion paints.

Filed: 1924-11-29
Abstract: 233,652. Soc. Technique d'Etudes et d'Entreprises pour l'Industrie, and Huguenin, A. May 6, 1924, [Convention date]. Axle-trucks and bogies.--A guiding arrangement for adjusting a bogie to the curvature of the wheel track comprises controlling elements which, when travelling upon the curved track will cause the axles, by means of servomotors, to assume the proper inclination in the horizontal plane in an automatic manner and in proportion to the radius of the curve. The bogie r, Figs. 2 and 3, has an arm s connected by a ball ioint t to the centre of a double-ended piston u working in a cylinder v connected by pipes I, II to a distributing valve A, the stem of which is connected by links o, m, k, to a longitudinal shaft g the centre of which is shown displaced in Fig. 1, upon which is fixed a double-armed lever f pivoted by rods e, e<1>, to cylinders c, c' respectively. The cylinders c, c<1> are connected by rods h, h<1> to the body of the vehicle and contain piston rods b, b<1>, carrying wheels a, a<1>, which are maintained in contact with the track by springs d, d', respectively. When the vehicle is turning on a curved track Fig. 6, the wheel a is pushed inwardly by the pressure of the rail, this rotates the levers f and k clockwise and as the double armed lever H is loosely mounted on the shaft g and is held fixed by an arm F, Fig. 2, from the bogie, the pivot of the lever m will be maintained fixed by the link l so that clockwise movement of the arm k effects an upward movement of the valve to admit pressure through the pipe I to the left hand side of the cylinder v which imparts an anti-clockwise movement to the bogie. The arm F moves to the right with the bogie and turns the double-armed lever H clockwise to draw down the links l, m, o, to return the valve to its neutral position and release the pressure from the servomotor. Water under pressure is supplied to the valve A by a motor x and pump w supplied by a tank z. The control may be carried out by a mechanical device with springs or weights, or an electric device.

Abstract: 765,490. Making, filling and closing bags. BOULY, H. G. (Kraft Foods Co.). Oct. 8, 1954 No. 29056/54. Class 94(1). The machine makes block-bottomed bags and transfers them to holders on an intermittently-operated endless chain conveyer which carries them in succession to stations where each bag is filled with viscous material, e.g. molten cheese, an insert of relatively stiff material is pressed on to the surface of the contents, the upstanding walls of the bag are folded over the insert and the closing flaps are sealed by the application of heat and pressure. The sequence of operations at the various stations is shown in Figs. 17 to 29. A sheet 192 of tissue paper bonded by wax to aluminium foil is withdrawn from a magazine and positioned beneath a die 198, Fig. 17, which then descends to carry the sheet through a folding box 196 whereby it is formed into a bag as shown in Figs. 18,-20, the final movement of the die inserting the bag into one of a series of holders 166, Fig. 21, detachably secured to the endless conveyer. The first step of movement of the conveyer carries the bag to the filling station, where a measured quantity of molten cheese 220, Fig. 23, is delivered through a retractable filling nozzle 580, and the next step positions the filled bag beneath a suction transfer member 228, Fig. 24, which is reciprocated vertically in an intermittently-rotating carrier to withdraw an insert 222 from the lower end of a magazine, swing it through 180 degrees and then press it on to the surface of the molten cheese. At the next station, Figs. 25 and 26, reciprocating, cam-operated blades 230 fold down the side walls of the bag and the rear transverse wall is folded down by a pivoted L-shaped member 232 which is operated through linkage by a cam-operated plunger. The next step of movement of the conveyer carries the bag beneath a fixed plate 234, Fig. 27, which folds down the front transverse wall 200, and the bag comes to rest beneath a heated die 236, Fig. 28, which descends to heat-seal the closing flaps. The die is recessed so that the apex of the upper flap is left unsealed to form an opening tab. The completed packages are ejected from the holders as they pass over the conveyer end sprocket, see Fig. 29, and fall onto a discharge conveyer.

Title: Apparatus for indicating the head, height and/or quantity of liquids in containers
IPC: G01F23/14
Filed: 1926-04-24
Abstract: 266,056. Rodman, J. B. April 24, 1926. Liquid-level pressure gauges.- A gauge glass 4 is mounted in a reservoir 3, and carries at its upper end an enlargement 36 to receive the indicating liquid in the event of an excessive pressure on the liquid in the reservoir. The cover 37 is provided with a projecting part 38 over the mouth of the gauge glass, leaving only a capillary passage for the escape of the liquid into the overflow chamber, so that the liquid will return iu an unbroken column containing no air bubbles. A similar capillary passage is provided between a bush 35 and the bottom of the reservoir 3, so that the whole of the indicating liquid may be forced into the tube 4 without the escape of air bubbles. A blow-off tube 47 containing mercury may be provided so that pressure is relieved just before the liquid rises to the top of the gauge. The gauge is applicable to apparatus for indicating the level in petrol tanks, of the kind in which the pressure necessary to force air through an open-ended tube dipping into the tank is measured, and the invention prevents the loss of indicating liquid due to excessive pressure caused by overfilling of a tank which may have a long neck.
