Abstract: EMULSIONS OF CROSSLINKED POLYDIORGANOSILOXANES         Abstract This invention is a method of producing a latex of crosslinked polydiorganosiloxane.  The latex yields an elastomer upon removal of the water.  The latex is prepared by homogenizing a mixture of hydroxyl endblocked polydi-organosiloxane, less than 75 millimoles of surface active anionic catalyst per kilogram of polydiorganosiloxane where said surface active anionic catalyst is dodecylbenzene sulfonic acid or hydrogen lauryl sulfate, and water to yield an oil-in-water emulsion.  This emulsion is then admixed with from 0.5 to 15 parts by weight of an alkoxy silicon compound selected from a silane of the formula R?Si(OR3)4-a where R' is a monovalent hydrocarbon radical of up to 12 carbon atoms, R3 is an alkyl radical of 1 to 6 carbon atoms, and a is 0 or 1, a partial hydrolyzate of the silane, or mixtures of silane and partial hydrolyzate.  The resulting emulsion is maintained at a temperature of about 15 to 30°C for at least 5 hours at a pH of less than 5 until a crosslinked polymer is formed, then the emulsion is admixed with sufficient base to raise the pH to greater than 7.  The crosslinked polymer present in the latex is reinforced by adding greater than 1 part by weight of colloidal silica sol or silsesquioxane to the latex.  Removal of water from the latex results in a reinforced elastomer.  This method yields a latex which can be applied and dried immediately after preparation to yield an elastomer.

Abstract: Abstract of the Disclosure A FOLDING BELT SYSTEM AND SAID BELT      A folding belt system having the head (13) and tail (12) pulleys twice the width of the support idler rolls and having a transition length of about 7 to 15 times the width of the belt between the fold or hinge lines, where transition width support rolls are located.  The folding conveyor belt is composed of a central belt section which has specially constructed flexible areas at each edge extending longitudinally the length of the belt to which are attached cover flaps (34 or 46).  The cover flaps completely enclose the load while it is conveyed.  This reduces spillage, dust, and contamination while providing highly enhanced conveying capacity.  The flaps may be of the same or different construction than the center section of the belt.    In it's preferred embodiment the fold belt is constructed by suitably providing the top cover of a fully cured conveyor belt with longitudinal grooves (30) formed by slitting and removing a strip of rubber at the appropriate locations to form preferentially flexible longitudinal hinge areas in the belt with the dominions outside the hinges comprising the cover flaps (34).  Alternately the hinge areas (44) can be molded into the belt at the time of manufacture.
