Title: Stabilisation of paints based on polymer latices
IPC: C09D125/06
Filed: 1969-01-17
Abstract: A nitrogen-containing compound (especially an amine) is added to paints based on latices formed by the emulsion (co)polymerisation of ethylenic monomers using phosphate emulsifying agents. Latices prepared using phosphate emulsifier (U.S. Patent 2,853,471 and British Patent 994,136) have an excellent resistance to light, heat and mechanical agitation. Coatings based on these latices are clear, water-resistant and do not discolour (British Patent 1,067,438). Their abrasion resistance is also excellent. The paints however are not stable and are completely coagulated after 1 to 24 hours at 50 deg.C. Stabilisation by this new technique makes commercial production of the paints possible.

Title: Appts. for converting thermoplastic sheet to hollow profiles - for rapid prodn. of sleeving or cladding by progressive annealed folding
Inventor: JARJAVAIL JEAN-CLAUDE
IPC: B29C53/04
Filed: 1974-08-09
Abstract: Appts. is for continuously converting thermoplastic sheet into open or closed profiles by passing the sheet between a series of elongated guides which form successive complementary folds and fix the fold by applying a narrow hot former to the inside of the crease during forming. Ancillary integrated equipment provides for dispensing the sheet from rolled stock, accumulating surplus sheet feed adjacent to any intermittent stationary treatment such as press. embossing, printing, etc, applying adhesive stripes to seal longitudinal joints on closed folded structures, and cutting the shaped profile to controlled lengths. Suitable for forming trough or hollow profiles at rates of e.g. 14-25 m/min. for producing, packaging or cladding for e.g. window or door frame profiles etc. The appts. offers fast throughput and is thermally efficient because the fixing heat is only applied along the crease zone and not wasted on adjacent planes of the sheet.
