Title: Process for preparing filled polymeric materials
Inventor: HOFFMAN FRANK EDWARD
IPC: C08K3/00
Filed: 1967-05-19
Abstract: A particulate filler is uniformly incorporated into a thermoplastic polymer by uniformly mixing the filler with discrete solid particles of the polymer in predetermined proportions while maintaining the polymer below the melting-point thereof, then uniformly dispersing the mixture in a further amount of the polymer in the molten state, while maintaining the mixture of molten polymer and filler above the melting-point of the polymer and removing any volatile material from the mixing zone.  In an example, 5 lb. of a diatomaceous earth were mixed with 100 lb. of polyethylene terephthalate flakes, and the mixture added over 1 hr. to 100 lb. of the molten polymer.  The process is said to be suitable also for such polymers as polyethylene isophthate, sebacate and 2 : 6-naphthalene dicarboxylate and poly-1 : 4-cyclohexane dimethylene terephthalate; polycarbonates, e.g. of bisphenol A and of diphenylol methane; and polyamides, e.g. nylons 6, 66 and 610.ALSO:A particulate filler is uniformly incorporated into a thermoplastic polymer by uniformly mixing the filler with discrete solid particles of the polymer in predetermined proportions while maintaining the polymer below its melting point, then dispersing the mixture in a further amount of polymer maintained above its melting point.  This process may be carried out in a conventional screw extruder.

Abstract: 254,550. Thorpe, W. Aug. 21, 1925. Reel and non-endless web apparatus.-A band 8 which is moved forward step-by-step to display advertisements, pictures, posters, show cards. &c., then automatically reversed to display them in the opposite order, is mounted on two rollers 2, 3 carried in a frame 1. The actuation is effected by a chain 10 running over a toothed wheel on the shaft 4 of the roller 2 and over an idle wheel 12. The chain 10 carries pins 11 which are engaged by spring pawls on a member 28 reciprocated vertically on guides 29 by rods 27 pivoted to one end of a hinged lever 25 having an up-and-down motion effected and positively controlled by two cams 21, 22 rotated by a motor 15. The pawls on the member 28 are carried by a sliding piece which pushes one or the other into engagement with the pins 11, and thus determines in which direction the chain 10 will be dragged. The sliding piece is controlled by a rotatable member 35, Fig. 4, carrying a spring- retracted sliding ring, whereby the member 35 is held in position, the member being operated by two spring-pressed rods 51, 52 pivoted directly and indirectly to two hanging links 49, 50, Fig. 2. These links are pushed in opposite directions by two pins located in two of a series of holes 45 in a worm wheel 44 driven by a worm 42 on the shaft 4, and cause the rods 51, 52 to be moved in turn into the path of the arms 36, 36<A> of the member 35. The pins can be placed in any two selected holes 45, the selection determining the positions of the band 8 which are exposed when reversal in either direction takes place. To ensure the winding-on roller rotating at a faster rate than the other the roller shafts 4, 5 are connected at each end by endless belts 61 passing round pulleys 59, 60, one of which is larger than the other. Each shaft 4, 5 carries a larger pulley, which is fixed thereto, and a smaller pulley, which is mounted thereon with one-way connection by a spring pawl 62 engaging a ratchet wheel 63. The tension of the belts 61 is controlled by adjustable jockey pulleys 67. To prevent spinning of the roller 2 a friction belt 68, attached by a spring 71 to a weight 73, is passed round one end. The lever 25 bears on the weight 73 at the end of each downward stroke of the member 28 to increase the friction on the roller 2.

Title: Compositions for making thermoplastic sheet materials and other moulded products
Inventor: GRIFFITHS LESLIE HERBERT
IPC: B29B7/88
Filed: 1950-08-30
Abstract: Compositions suitable for the production of thermoplastic moulded products are made by distributing a pulverulent polyvinyl compound and a liquid plasticizer therefor which gels the polyvinyl compound on heating throughout a flock of fibrous material and heating the resultant fibrous mass sufficiently to anchor the pulverulent polyvinyl compound to the fibres of the material without effecting coalescence of the particles of the polyvinyl compound and plasticizer to a homogeneous mass.  The amount of plasticizer is preferably sufficient to form a film of plasticizer on the flock. The polyvinyl compound may be polyvinyl chloride or a copolymer of vinyl chloride with vinyl acetate and/or vinylidene chloride in which the vinyl chloride units predominate and the plasticizer may be dibutyl, di-hexyl or di-octyl phthalate or tricresyl or trichlorphenyl phosphate.  The flock may be of wool, cotton, asbestos, glass wool, slag wool or regenerated cellulose.  A pulverulent filler, such as limestone, or a pigment or both may be distributed throughout the flock of fibrous material before the heating step and there may also be incorporated a non-gelling plasticizer which may be a petroleum hydrocarbon.  The fibrous mass may be used for making sheet material suitable for flooring by feeding it to a calender, and marbled products may be made by simultaneously supplying to the calender differently coloured fibrous masses.  Specification 723,643 is referred to.

The movable contacts are normally maintained closed against the bias of a spring 225 by a latch 207 connected by a spring 211 to a lever 199 which is pivoted on a lever 197 rigidly connected to the fork 151. When the fork 151 is turned clockwise by the lug 153 on the switch arm (not shown), the spring toggle formed by levers 197, 199 and spring 211 is moved over-centre and a latchrelease member 213 on the lever 197 turns the latch 207 to release the moving contact assembly. The contacts are closed and relatched when the fork 151 is turned anti-clockwise so causing the free-end of the lever 199 by its engagement with a pin 219 on the moving contact assembly, to move the assembly back to the closed position shown. When the contacts separate, the arcs drawn cause gas to be evolved from the resin sleeve and liners, washers 173 and 192 acting to cause the gas to flow towards a vent 161. This vent is closed by the moving contact 170 when in the fully open position so that should the extinction of the arc not be complete, the direction of flow of the gas is reversed. Under these conditions the gas is vented from the actuating housing 185 and indicates unsatisfactory operation.
