Abstract: 190,718 CAN/RRT     LOW-PERMEABILITY HOLLOW SPHERES AND PIPE FILLED WITH THE SPHERES FOR TEMPORARY WEIGHT REDUCTION                     Abstract Pipe adapted to be installed underwater at increased ocean depths by practical pipe-laying procedures comprises a porous cement shell filled with hollow spheres that are slowly permeable to water under pressure.  The cement shell is filled with a sufficient volume of the hollow spheres to make the pipe only slightly heavier than sea water, providing a reduced weight that overcomes previous difficulties in laying pipe at great depths. Over a period of time after the pipe has been installed underwater, the hollow spheres gradually fill with water and make the pipe rest stably on the ocean bottom. The preferred spheres comprise porous core spheres coated with thin coatings that partially seal the spheres to the needed degree of permeability.

Abstract: VITAMIN ENCAPSULATION     Abstract of the Disclosure Disclosed is a process for encapsulating oils and oil-soluble substances in multi-compartmentalized, mechanically stable microcapsules.  The process comprises the steps of first forming an emulsion consisting of a continuous phase comprising an aqueous solution of an alkali metal alginate and optionally a water-soluble, alcohol-insoluble filler such as a polysaccharide, and a dispersed phase of an oleophilic substance such as one or more vitamins dissolved in an oil.  The emulsion is then formed into droplets which are thereafter immersed in an alcoholic solu-tion of multivalent cations, to produce a shape-retaining algi-nate matrix filled with precipitated polysaccharide and enclosing plural oil droplets.  The vitamins are thereby protected from oxidative degradation and can be handled like conventional crystalline solids.

Abstract: Abstract of the Disclosure An electrical governor system for a turbocharg-ed diesel engine which eliminates objectionable puffs of smoke when gears are shifted, by limiting the rate of fuel delivery to the engine at such times.  The response charac-teristics of the turbocharger to changes in kinetic energy of the engine exhaust flow are determined and stored in a microprocessor memory.  The engine operating parameters are monitored to produce signals representative of engine speed and fuel delivery rate, and these signals are sup-plied to the microprocessor to cause it to generate a signal representative of the maximum rate at which fuel can then be delivered to the engine without producing objectionable exhause smoke.  The latter signal is used to control the fuel-control each automatically, through a stepping motor arrangement, at appropriate times to limit the fuel delivery rate to said maximum and thus avoid objectionable smoke puffs.
