Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a novel process for the production of polyvinyl chloride having a low vinyl chloride monomer content, the latter being removed from a slurry or latex which result from polymerization of vinyl chloride in aqueous media.  In the novel process vinyl chloride is removed from a slurry or latex that con-tains from about 1000 parts to 15,000 parts by weight of vinyl chloride per million parts by weight of the slurry or latex and from 5% to 50% by weight of a polymer selected from the group consisting of polyvinyl chloride and copolymers of vinyl chloride with at least one monomer copolymerizable therewith that comprises (a)  contacting the slurry or latex with 0.5% to 20% by weight, based on the weight of the slurry or latex, of an organic liquid selected from the group consisting of vinyl acetate, methyl-ene chloride, di-tert-butyl-p-cresol, and mixtures thereof, at a temperature in the range of 25°C to 125°C, and then (b)  removing vinyl chloride vapor from the slurry or latex.

Abstract: High Visibility Lift Apparatus Abstract Apparatus for lifting or moving loads require high operator visibility and simplicity of construc-tion.  For example, in a mast assembly such as can be used on a fork lift truck or other cargo handler it is desirable to maximize visibility through spaced-apart uprights.  Also, free lift of a carriage which engages the load will maximize visibility in that the movable uprights will not be elevated above the fixed uprights when raising the carriage to move the load.  In the apparatus, first and second lifting elements or jacks are mounted adjacent the uprights for visibility.  The lifting elements are interconnected by a load sharing member for free lift and to distribute the forces encountered in raising the load more equally between the lifting elements and the chains.

Abstract: ABSTRACT OF THE DISCLOSURE    In a method of forming a thin sheet glass by the float process, a thin layer of molten glass is formed by making molten glass flow through a sluice formed on the surface of a molten metal bath, and the glass layer is drawn lengthways of the bath to further reduce its thickness and advance while its upper surface is exposed to a cooled atmosphere.  The sluice is a vertically narrow gap between the surface of the molten metal and a lower end face of a wall extending above and transversely of the molten metal bath.  By ingeniously shaping a lower end portion of this wall and avoiding particularly heating the molten glass in the vicinity of the sluice, it has become possible to obtain defectless sheet glass thinner than one millimeter.

Abstract: ABSTRACT OF THE DISCLOSURE:            The present invention refers to a paper making process with improved retention and binding of fillers and second grade fibers. It is characterized by the use of an amphoteric mucus like compound as binder.  This compound is the reaction product between cationic starch of low charge density and an anionic polymer of high charge density as carboxymethyl cellulose.  The compound has amphoteric and mucous characters and should be used for paper making, while in a unique transient structure.  This structure is characterized by filler particles being enclosed and finely distributed in droplets of the highly hydrated but substantially water-insoluble mucous compound.          According to the invention this transient structure may further be reorganized to a less hydrated and more resist-ant gel structure, still enclosing the filler.  This gel structure can stand the draining forces on a paper machine wire.  This structural reorganization is achieved by reac-tion with colloidal inorganic polymers of very high surface charge as polysilicic acid and polyaluminium compounds.          The process yields papers of high strengths and filler retentions of more than 90% at a single wire passage even at extreme filler contents of 30-60% of the paper weight.

Abstract: Abstract A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time for one incoming field.  The progressively scanned image contains interstitital lines between the lines of one field  and consequently the line-scan structure is made less visible  but the flicker rate is undesirabley decreased. In order to increase the flicker rate, additional progressively scanned images are generated at a rate equal to or greater than the incoming field rate.
