Abstract: 1347568 Making spherical particles XEROX CORP 19 April 1971 [23 March 1970] 24975/71 Heading B3A [Also in Divisions B5 and G2] A method of making spherical particles of substantially uniform size comprises cutting rods of a malleable metal into lengths substantially equal to the rod diameter and continuously impingeing the cut rods against a rigid surface. The particles are used in a developer for latent electrostatic images. The rods are of steel, copper, nickel, aluminium, brass and the like and are drawn down to a diameter of 50-1000 microns. Stainless steel wire when cut is fed to a vibrating mill containing ceramic balls of large diameter relative to the particles and occupying about 80% of the mill volume. Alternatively cut aluminium, brass or low carbon steel wire is impinged against hardened steel targets by a centrifugal throwing wheel and is recirculated via a bucket conveyer. The rods may be cut either individually or in sheaths and the cut rods may also be worked in ball mills, tumbling mills, blast mills and the like. The particles may be coated by conventional techniques to alter their triboelectric properties.

Title: Process for recovering cyclopentadiene
IPC: C08F36/04
Filed: 1945-01-05
Abstract: Benzol forerunnings containing cyclopentadiene are stored at atmospheric temperatures and pressures out of contact with oxygen or oxygen-containing gas to polymerize cyclopentadiene to the dimer with at most minor amounts of higher polymers, other constituents originally present are removed by distillation at not more than 120 DEG  C. to avoid depolymerization and the dicyclopentadiene purified. The forerunnings, which must be substantially free of benzene and its homologues, are stored in closed containers at not substantially below 15 DEG  C. or above 40 DEG  C.  A halide catalyst such as stannic chloride or boron fluoride may be added.  The storage time varies from a few days to a few weeks.  After the distillation, the residue is fractionated under vacuum to recover the dimer.  In an example, forerunnings of B.R. 31-46 DEG  C. are stored at 22-25.5 DEG C. for 34 days and solid dicyclopentadiene recovered.  This may be transported in an inert atmosphere such as natural gas or nitrogen, and depolymerized as required to cyclopentadiene for use in the production of synthetic rubber or, with maleic anhydride, resins.ALSO:Benzol forerunnings containing cyclopentadiene are stored at atmospheric temperatures and pressures out of contact with oxygen or oxygen-containing gas to polymerize cyclopentadiene to the dimer with at most minor amounts of higher polymers, other constituents originally present are removed by distillation at not more than 120 DEG  C. to avoid depolymerization and the dicyclopentadiene purified.
