Abstract: 1314570 Polymerising a coating on particles and microballoons GENERAL TIRE & RUBBER CO 1 Oct 1970 [26 Nov 1969] 46719/70 Heading B2E [Also in Division C3] Polymer coatings are formed on particulate or microballoon matter by (a) wetting the surface of the matter with a solution comprising (i) a liquid or liquefiable polymerisable monomer selected from acrylic and substituted acrylic acids, esters of the aforesaid acids containing less than 20 carbon atoms in the ester molecule, acrylonitrile, vinyl chloride and mixtures thereof and (ii) a free radical generating agent selected from hydrogen peroxide, methyl ethyl ketone peroxide, organic hydroperoxides and mixtures thereof, and (b) exposing the wetted surface to an atmosphere containing sulphur dioxide (sufficient to provide a polymerisation rate of at least about 1 mole per litre of monomer per second) to rapidly polymerise the monomer on said surface, the matter being maintained in the form of microballoons or un-bound particles during said exposure. With the microballoons, coating can be effected on both the inner and outer surfaces of the microballoon wall; reinforcement of the microballoons may also occur. In a modification, the coated matter is treated again with a different liquid or liquefiable monomer to form a second layer of polymer thereon. The monomer solution can be applied by slurrying the matter therein, or by spraying the solution onto the matter carried on a moving conveyor belt. Particulate matter which can be treated includes calcium carbonate powder, barium sulphate, kaolin, carbon black, silica, titanium dioxide, iron oxide, organic resins and polymers, Fuller's earth and wood flour; a particular microballoon material illustrated is cellular siliceous glass spheres marketed under the Trade Mark "CORCEL". The coated materials are useful for incorporation into thermoplastic or thermosetting resins, and also polymeric foams.

Abstract: 1,236,742. Photographic type-composing. INTERNATIONAL PHOTON CORP. 10 Oct., 1969 [11 Oct., 1968], No. 48378/68. Heading B6W. Coded information representing characters or functions is passed from an input keyboard, tape recorder or storage 70, Fig. 1, to a countercomparator 76 where its numerical value is compared with the number of pulses from a character matrix 86 so as to illuminate a flash tube by a circuit 84 when the signals correspond. A box 78 identifies function codes and inhibits the activation of circuit 84 when they occur. A matrix drum 92, Fig. 3, carries a plurality of matrix strips 94, Fig. 6, each carrying one or several rows of characters and corresponding timing slits such as 2, 3, 6, 7, 10, 12 together with intervening slits representing machine functions, such as 1, 4, 5, 8, 9, 11. Thus, the numerical value of character S is represented by the number of slits, namely ten, from the end of the strip. Since no flash takes place for a function code, said code requires no blank space on the strip. Light from the flash tube 104 passes through the selected character and is deflected by a prism 142 movable in the direction of the arrow as the composition of a line proceeds to a selected lens 126 on a lens turret and thence to a film 128. A second optical system 120, 124 and film 130 may be used in conjunction with another matrix strip, using a common control circuit on a time-sharing basis.

Abstract: 1,002,631. Land mines. WASAG-CHEMIE A.G. Dec. 21, 1962 [Dec. 21, 1961], No. 48452/62. Heading F3A. A hollow-charge land mine comprises a double-walled casing 1 housing a hollow charge 3 having a liner 4, a propellent charge 5 being housed in the hollow charge and a double-walled cover 6 carrying a fuze 9 being placed over the propellant. Axially arranged in the charge 3 is a primer charge 12 and a delay detonator 11 held in place by a plug 13. A fuze (not shown) to fire an ignition charge 14 may be inserted in a radial passage in the cover 6 and may be an electric igniter or of the push-pull type. When charge 14 is fired and fuze 9 ignited thereby, the propellant 5 is initiated and blows off the cover 6 together with any overlying camouflage material. Flame from the charge 5 passes through a flash passage 10 and fires the detonator 11, which in turn fires charge 12 to initiate the charge 3. The space between the double walls of the casing 1 and cover 6 may be filled with passing such as a foamed material. As propellant either a mono- or polybasic nitrocellulose powder or gunpowder may be used and the hollow charge may be trinitrotoluene, tetranitropentaerythritol, or cyclotrimethylenetrinitramine or mixtures thereof. Liner 4 and the casing walls may be made of copper or for a non-detectable mine, non- metallic materials such as plastics, wood or ceramics may be used.

Abstract: 1368428 Filling containers BECKER EQUIPMENT & LIFTS Ltd 12 Oct 1971 [12 Oct 1970] 48460/70 Heading B8T [Also in Division G3] A main valve 6 and a by-pass valve 22 in a liquid filling apparatus are controlled by respective pressure-sensitive diaphragm valves 11, 26 which detect a rise in pressure in pilot tubes 12, 23 depending within a filler pipe 1 when the liquid being filled into a container 3 blocks their exits 13, 24. The tubes 12, 23 are supplied with air at low pressure from an air circuit, Fig. 2, through pressure reduction valves 15, 25 respectively. A manually operated button 16 controls a valve 17 supplying air to one side of the diaphragm of an actuator 10, which moves to overcome a spring loading the main valve 6 and hold it open, so allowing liquid to flow. When the tube 12 is blocked, diaphragm valve 11 opens, allowing air to flow to reset the valve 17 and so shut off air to the actuator 10 to close the main valve 6. The by-pass valve 22, which is actuated by the initial depression of button 16, through valves 17 and 27 and a diaphragm actuator (not shown), opens the by-pass 21. Since the by-pass 21 is of a relatively small bore the rate of fill is reduced until rising liquid blocks the outflow of tube 23. The by-pass valve 22 is then shut, since rise in pressure in the tube 23 actuates valves 26 and 27. The filler pipe 1 may be automatically lifted and lowered by means of a double-acting piston and cylinder 49 supplied with air through a valve 50 set by a manual button 53.
