Patent GB-1029566-A (GB)
Title: Polymer compositions
Inventor: EVANS ARTHUR WALLACE
IPC: C08F2/44
Filed: 1962-08-21
Abstract: Pigmented polymer compositions are prepared by mixing a solid, particulate pigment, water, a surface-active agent and a water-insoluble polymerizable monomer, the pigment being initially in the aqueous phase and the surface active agent being such that it causes transfer of pigment into the monomer, and thereafter polymerizing the pigment containing monomer thus produced. Specified monomers are vinyl acetate, alkyl acrylates, methacrylates, maleates and fumarates, acrylonitrile, vinylidene chloride, styrene and butadiene.  The pigment may be titanium dioxide, e.g. a rutile pigment coated with alumina, titanium dioxide or silica.  Specified surface-active agents are octadecylamine acetate and the octadecyl ester of carboxymethyl trimethyl ammonium chloride.  Dispersion stabilizers, e.g. linseed oil modified pentaerythritol containing alkyd resins, may be present, and the polymerization may be effected in the presence of conventional redox catalyst systems, emulsifying agents and protective colloids, e.g. methyl, ethyl, hydroxymethyl or hydroxyethyl cellulose, and plasticizers, e.g. dibutyl phthalate. The products may be used in the preparation of coating compositions.  In an example, vinyl acetate containing a linseed oil modified pentaerythritol containing alkyd resin is added to an aqueous dispersion of alumina/titania coated rutile pigment and octadecylamine acetate. Hydroxyethyl cellulose, polyethylene oxide, trisodium ethylenediamine tetraacetate and sodium bicarbonate are added, and the vinyl acetate is polymerized in the presence of ammonium persulphate, sodium metabisulphite and benzoyl peroxide.ALSO:Substrates may be coated with pigmented polymer compositions prepared by mixing a solid particulate pigment, water, a surfact active agent and a water-insoluble polymerizable monomer, the pigment being initially in the aqueous phase and the surface active agent being such that it causes transfer of the pigment into the monomer, and thereafter polymerizing the pigment containing monomer. The monomer may be vinyl acetate, an alkyl acrylate, methacrylate, maleate or fumarate, acrylointrile, vinylidene chloride, styrene or butadiene.  The pigment may be titanium dioxide, e.g. anatase or rutile coated with alumina, titania or silica.  The preferred surface active agents are amine and quaternary ammonium salts.  In one example tin plated panels are coated using a doctor blade with paints prepared by mixing alumina/titania coated rutile, water, octadecylamine acetate and vinyl acetate containing a linseed oil modified, pentaerythritol-containing alkyd resin, adding hydroxyethyl cellulose, polyethylene oxide, trisodium ethylenediamine tetracetate, sodium bicarbonate and dibutylphthalate and polymerizing the vinyl acetate in the presence of ammonium persulphate sodium metabisulphite and benzoyl peroxide.

Patent GB-920644-A (GB)
Title: Sales registering device for fuel pumps
Inventor: SETTLFMIRE EUGENE F
IPC: B67D7/22
Filed: 1960-09-19
Abstract: 920,644. Dispensing liquids. GAS REGISTER CORPORATION. Sept. 19, 1960, No. 32184/60. Class 116. [Also in Group XIX] A fuel pump with a main register 8, 9 is provided with a number of individual counters 17 for registering the amount dispensed by each attendant, each of which counters is brought into operation by a key-operated lock which also releases an interlock preventing completion of the resetting operation of the main register. The counters 17 are pivotally mounted at 15 and their drive pinions 20 are normally out of register with meshing pinions 13 on a drive shaft 14 connected to the main register drive. Actuation of a lock 22 by an attendant rotates an arm 23 to lift a slide 26 operating the interlock release and rotates a lever 32 to lift the counter body so that its pinion 20 meshes with the drive shaft 14, a latch 33 on the arm 32 maintaining the counter in its engaged position after removal of the key. The slide 26 is biased upwardly by a weak spring 29 and is connected by a wire 30 to an interlock lever 97, Fig. 5, biased to interlock position with a cam 89 on the reset shaft 38 of the main register by a strong spring 99. Another interlock lever 47, Fig. 6, prevents operation of the pump switch 5 until the main register has been zeroized and the attendant's lock operated. Operation.-Replacement of the nozzle after a dispensing operation rotates lever 43, Fig. 6, to " off " position 43A in which interlock lever 47 engages a notch 46 to prevent further dispensing before operation of the reset shaft 38. For the next dispensing operation an attendant must first operate reset shaft 38 through about 400 degrees to an overtravel position, during which a cam 40 moves a toggle device 52 to a position to load lever 47 towards disengaging from notch 46 and also moves a friction disc to a position in which projection 57 prevents disengaging of lever 47. In the overtravel position of the reset shaft the second interlock lever 97, Fig. 5, is forced by spring 99 into a notch 98 in a cam 89, whereby slide 26 is pulled downwards to disengage the previously engaged individual counter 17. The travel of the reset shaft 38 operates a spring-loading arrangement to urge the shaft 38 back through 40 degrees to its zero position. To permit this return the attendant must operate his individual counter lock 22 which raises slide 26 against spring 99 to engage his counter 17 with the drive 14 and simultaneously release the interlock 97 to free shaft 38. During its return to zero position, the main register is finally zeroised and projection 57, Fig. 6, is removed from beneath lever 47 to permit the toggle 52 to free lever 47 from notch 46 which frees lever 43 to permit operation of the pump switch 5 when the dispensing nozzle is lifted from its holder.

Title: Improvements in or relating to machines for verifying and punching record cards
IPC: G06K5/00
Filed: 1936-11-26
Abstract: 491,142. Statistical apparatus. YOUNGBERG, W. K. Nov. 26, 1936, No. 32418. Convention date, Nov. 26, 1935. [Class 106 (i)] [Also in Group VIII] Verifying perforated cards. - A machine for verifying and punching record cards has original and duplicate card receiving means and comprises manually operable keys controlling the punching mechanism for the duplicate card, sensing mechanism controlled by the original card and means controlled by the sensing mechanism adapted to prevent control of the punches by the keys to produce any punching on the duplicate card save that corresponding to the punching on the original card, and to call attention to an error. The receiving means 9, 10, Fig. 1, for the original and duplicate cards O, D, are attached to a rack 12 adapted to be moved step-by-step to the left by a spring 23, Fig. 2. A hole in the original card is sensed by one of a series of brushes 32, Fig. 3, which contacts with a plate 38 to close the circuit of an electromagnet 41, Fig. 2, to attract a spring-urged armature 62 and remove lug 64 from the path of a lever 54. The energized magnet 41 also attracts an armature 67 to engage a pawl 70 with the rack 12. Upon depression of the corresponding key K contacts 80 are opened to allow the armatures 62 and 67 to return to their normal positions, the lever 54 engaging the appropriate punch 57 to perforate the duplicate card and rocking the escapement 75 to allow a movement of the rack 12, equal to the width of a card column. If no hole is to be punched in a column, a space key S is depressed to actuate the escapement 75. If, a hole is sensed in the original card in the latter case, or if two holes have been punched in one column, the pawl 70 prevents movement of the rack 12. At the end of its travel the rack 12 is returned by means of a handle 19 fixed to a bar 18 slidable in relation to the rack 12 against the action of a spring 17, a projecting fin 91 on the bar pushing a spring-urged member 94, Fig. 3, out of engagement with a pin 37 to raise the brushes 32 during the return movement. In an arrangement for mechanical sensing, the passage of a sensing pin 110, Fig. 10, through a perforation actuates Bowden mechanism 116 to remove a lug (not shown) from the path of the corresponding lever 54. At the same time a lever 126 is moved to engage a pawl 133 with the rack 12. When the appropriate key K is depressed, contacts are closed to energize a magnet 132 which resets the pin 110 and the pawl 133. The machine may be used for verifying only, no duplicate card being used, or may be adapted for punching only. In this case a device 145, Fig. 12, withholds the armature 67, Fig. 2, and prevents engagement of the pawl 70 with the rack 12 ; therefore, since all the brushes 32 will contact with the plate 38 to release the holding lugs 64, the keyboard will be free for manipulation. In the mechanical sensing arrangement the pawl 133, Fig. 10, is moved laterally out of engagement with the rack 12 to achieve this object.
