Title: Improvements in or relating to plastic films
Inventor: HEDGE DEREK G
IPC: C08J7/052
Filed: 1961-11-08
Abstract: An organic thermoplastic film is coated with a solution in an organic solvent of a heat-sealable polymer containing finely-divided polymethyl methacrylate particles, the particles being large enough to confer slip properties but not so large that they cause haze, the organic solvent being a non-solvent for polymethyl methacrylate and for the material of which the film is made, and the coating dried to remove the solvent.  The bulk of the particles may have a size in the range of 0,1-2 microns, especially 0,1-0,7 microns, and the thermoplastic film may consist of a linear polyester, preferably polyethylene terephthalate, or a poly-a -olefine, e.g. polythene or polypropylene.  Heat-sealable polymers mentioned include polyvinyl acetate, partially hydrolysed polyvinyl acetate, butadiene/acrylonitrile copolymers, butadiene/styrene copolymers, copolymers of vinylidene chloride with vinyl chloride or alkyl acrylate, copolymers of vinyl acetate with vinyl chloride or ethylene, copolymers of vinyl chloride with ethylene, and especially copolymers of vinylidene chloride and acrylonitrile (e.g. 80-95% / 20-5% copolymers).  Specification 707,549 is referred to.

Abstract: 1,247,997. Bleach composition. UNILEVER Ltd. 12 Aug., 1969 [14 Aug., 1968], No. 40283/69.. Heading D1P. A low density bleach composition is prepared by spray drying a base comprising a phosphate builder (preferably sodium tripolyphosphate, potassium tripolyphosphate tetrasodium pyrophosphate, tetrapotassium pyrophosphate sodium acid pyrophosphate, sodium trimetaphosphate or sodium hexameta phosphate) a borax fluffing agent (borax pentahydrate or borax decahydrate) a solubilizing agent (preferably sodium toluene sulphonate or sodium xylene sulphonate) and then adding to the spray dryed base a chlorinating agent for example potassium dichlorcyanurate; sodium dichlorocyanurate; [(mono-trichloro)- tetra-(mono-potassium dichloro)] penta-isocyanurate; 1,3-dichloro-5,5 dimethyl hydantoin; H,H'-dichlorobenzolyleneurea; paratoluene sulphondichloroamide; H,H'-dichloroazodicarbonamidine; H-chloroacetyl urea; H, H'-dichlorobiuret; chlorinated dicyandiamide; chlorinated trisodium phosphate; or the sodium derivative of H-chloro-p-toluene sulphonamide and as a cementing agent an aqueous solution of tetrapotassium pyrophosphate or sodium tripolyphosphate or mixtures thereof. Optionally the base may contain fillers (sodium sulphate, potassium sulphate, sodium carbonate and sodium sesquicarbonate) fluorescent dyes, a source of cerium ions, solourants and surfactants (either anionic or non-ionic). To make the base all the compounds with the exception of the phosphate builder are mixed together, water is added and the mixture is heated to 160‹F. The phosphate builder is then added to give a slurry containing between 10 and 40% by weight of solids at 160 to 180‹F which is then homogenised and spray dried in a tower where it falls under gravity against a counter current of air having an inlet temperature of 600 to 700‹F and an outlet temperature of between 200 and 300‹F. The spraydryed base so produced is then transfered to a rotating horizontal drum where the chlorinating agent is blended with the base and the cementing agent is added. The bleach so prepared is dryed at below 175‹F by blowing warm air through the drum in order to remove tackiness. If desired perfumes, de-dusting oils, colourants, anti-yellowing agents, and moisture scavengers may be added to the bleach composition. Typically the final bleach composition has a particle size which ranges between 25 and 40 mesh and a density of less than 0.6 g/cc.
Patent GB-403317-A (GB)
Abstract: 403,317. Fluid actuated valves. KROMSCHRODER AKT.-GES., G., Osnabr³ck, Germany. June 29, 1933, No. 18539. Convention date, June 30, 1932. [Class 135.] Valves controlled by pilot or relay valves.-A valve device for controlling the lighting of a gas burner having a main valve actuated by gas pressure under the control of a thermally actuated auxiliary valve has the thermal element arranged to actuate a second valve controlling an additional supply to the igniting burner. In the form shown in Fig. 1, an annular valve member 11 carried by a diaphragm 10 co-operates with an adjustable seat to control the additional supply admitted through a passage 6. A valve member 15 actuated by a bi-metallic strip 1 co-operates with a seat on the member 10 to control the flow of gas passing from the actuating chamber of the main valve through a passage 7. The two gas flows unite in the member 16 to feed the igniting burner 15 and a small port supplying a heating flame 3. The passage 14 in the member 11 is formed as a nozzle to cause an ejector effect reducing the pressure in the chamber 9. When the thermal strip cools, the closure 13 is first closed and then the closure 12, opening being effected in the reverse order. In a modification the member 11 is formed as a sphere and co-operates with conical or spherical members. In another form in which the bi-metallic curls downward when heated, two separate valves are successively operated and in a variation of this form a metal diaphragm. replaces the bi-metallic strip. In the form shown in Fig. 5 an adjustable annulus 25 carried by an expanding diaphragm 2 bears against a valve member 27, adapted when the diaphragm cools to move against a spring 26 to engage a seat member 28 and then depress the seat member against a spring 29 to disconnect the conduit 6 from the burner and connect it to the passage 7. A protective guard 34 is arranged above the diaphragm 2. In variants of this form arrangements are made whereby a reduced flame burns within the device when the supply is decreased and is transferred to the igniting burner when the pressure is restored.

Apparatus for counting small articles comprises a circular plate rotatable about an axis inclined to the vertical and fed with the articles to be counted which are displaced by centrifugal force to the edge of the plate where they are transferred to a rotating ring which feeds them singly to an electrical counter. As described, articles to be counted are fed on to a circular plate 20 which is rotated about an inclined axis 21 and is surrounded in a frusto-conical ring 22 surrounded by a fixed cylinder 28 and rotating about a vertical axis, and a cylinder 25 also rotating about a vertical axis. The velocities of the plate 20, cylinder 25 and ring 22 are of progressively increasing magnitude. Articles pass from the plate 20 to the ring 22 at the lefthand side of the Figure, the width of the ring 22 allowing only articles in single file to be fed to an exit channel 6 whence they are ejected via rapidly rotating rollers 9 to interrupt at 11 a beam of light thereby causing a photo-cell 13 to step on an electric counter 14 having an indicator 8. The articles are then directed by a blade 15 into one or the other of two channels 16, 17, the blade 15 being controlled by the counter 14 to pass successive predetermined numbers of the articles to the channels 16, 17 alternately.

Driving belts having polyester reinforcing cords therein, or a sleeve which is to be cut into belts subsequently, are prestretched, after fabrication and curing, by a process comprising heating the belts to between 150‹ and 350‹ F.- preferably 200‹ F.- and then cooling them, while they are stretched by about 1¢% relative to their original length. The belts are placed round rollers 24, 36, rotatably supported on a fixed bar 18 and a movable bar 25, respectively. To allow placing and removal of the belts, one end of each roller shaft 23, 35 bears in an arm 20a, 31 which is movable axially of the roller by rotation of a handle 21, 33 on a spindle 19, 30 screwed into the bar 18, 25, the arms being freely rotatable on the spindles. The bar 25 and roller 36 are moved by an hydraulic jack 29 to tension the belts, and the roller 24 is driven by a motor 42 to slowly move the belts. An hydraulic jack 14 lowers a carrier 16 carrying infra-red heaters 17 which are then energized. After a heating period of about 6 minutes, the heaters are de-energized and raised, and a cooling water spray 44 turned on. Finally the motor 42 is stopped, the jack 29 operated to slacken the belts, and the belts removed.
