Abstract: Abstract of the Disclosure A system for generating multicolor light images from a laser beam is disclosed.  An arrangement prism produces several different color collimated light beams from the laser beam.  Each different color light beam is directed at a different set of x-y axis moveable mirrors.  Each set of x-y axis moveable mirrors is moved in a predetermined manner to cause the light beam reflected therefrom to describe a desired image.  The different color collimated light beams are moved by a beam torquer device so as to cause interception and direction of at least one of the different color beams to a respective one of the x-y moveable mirrors which is different from the x-y moveable mirror-which would receive that particular color beam when the different color beams were stationary.  This permits images of multiple colors to be achieved.

Abstract: APPARATUS AND PROCESS FOR MOLDING      OF HOLLOW ARTICLES               Abstract of the Disclosure Disclosed is an apparatus and process for the mold-ing of hollow articles such as full length Foley catheters.          The apparatus preferably comprises a mold with two lumen forming wires longitudinally disposed therein.  A set of two receiving wires are spaced distally from the distal ends of the lumen forming wires and are longitudinally aligned there-with.  A first follower is slidably disposed about the lumen forming wires in close abutment with the wires and inside wall of the mold.  The first follower is preferably disposed toward the proximal end of the mold and preferably at least two other followers are provided spaced distally of the first follower.          One of the other followers preferably bridges the space bet-ween the lumen forming wires and receiving wires.  Sets of gates are preferably provided along the length of the mold in fluid communication with a source of molding material.  In practice, molding material is injected into the molding channel at the proximal end of the mold and flows longitudi-nally toward the distal end of the mold while pushing the first follower along the wire ahead of it.  As the follower proceeds toward the distal end of the mold, it engages and pushes the remaining followers toward the distal end of the mold.  At the beginning of the molding process, each set of gates has a follower that is transversely aligned with it so as to seal the set of gates and prevent the flow of molding material through the set of gates and into the mold.  In this fashion, molding material is not introduced through a set of gates and into the mold until all followers are distally located from the set of gates.

Each lowered pallet is raised by a piston and cylinder and latched in a burden carrying position to the inner wall.  The pallets and walls are supported for rotation along the trackway by water cooled supporting grid to minimize differential expansion and contraction of component parts of the machine as they are subjected to differential temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE       Expandable styrene polymer particles having reduced flammability are made by incorporating from 0.1 to 15 weight per cent of non-polymeric organic halogen compounds into the polymer during impregnation of the polymer particles with a blowing agent in aqueous suspension. Temperatures greater than 90°C., during the impregnation step, often cause degradation of the halog  compound and subsequent degradation of the polymer at the particle surface.  The addition of certain hindered phenolic anti-oxidants, such as di-tert-butyl-p-cresol, stabilizes the halogen compounds in the suspension system to temperatures up to 125°c.
