Abstract: ABSTRACT OF THE DISCLOSURE   Cells or multicell batteries are provided with vents comprising fiber-filled plastic tubes.  The plastic tube walls are formed of a hydrogen-permeable, liquid-impermeable, plastic material and the fibers which fill the interior of the tube serve to maintain an open gas diffusion passage through the tube.  The vents extend through seals between battery components into electrochemically active regions of the battery, into gas-permeable regions of the battery outside of the electrochemically active regions, or both.  The fiber filled tube can terminate in the cell interior when the end positioned within the cell is sealed with a hydrogen-permeable, liquid-impermeable, plastic layer, or the tube can extend across the battery length or width.  At least one end of the tube is open to the atmosphere.

Abstract: Abstract of the Disclosure A process for producing uniformly small spherical par-ticles of crystalline, normally solid condensation polymers is described.  The process of this invention further provides high yields of hydrophobic, non-agglomerating particles in a useful size range directly, without the need for subsequent processing, and is carried out by forming a dispersion of small liquid particles of the crystalline polymer in certain aprotic liquids containing 0.1 to 20% by weight of the poly-mer of an acid-modified polymer of propylene in a specified manner, cooling the dispersion with agitation until the liquid particles solidify and recovering the particles.

Abstract: DUAL MODE AC MOTOR DRIVE SYSTEM   ABSTRACT OF THE DISCLOSURE         Disclosed is an AC motor drive system having a variable frequency, variable magnitude AC current supplied from a  controlled inverter coupled to a variable DC current source in the form of a converter by way of a DC link including an inductor.  The AC motor load is controlled so as to have dual modes of operation in order to optimize torque at any speed which can be produced within the voltage and current limitations of the variable frequency power source.  The first mode comprises a constant slip or constant angle mode for operating speeds up to the corner point speed which is defined as the speed at which the motor voltage at full torque matches the maximum voltage the variable frequency inverter coupled thereto can provide.  Thereafter, the system enters the second mode by automatically shifting to a constant horsepower variable slip or changing angle mode for operating speeds beyond the corner point speed.

Abstract: Abstract: CONTINUOUS PROCESS FOR THE PRODUCTION OF PEROXYCARBOXYLIC ACID COMPOSITIONS     Peroxycarboxylic acid compositions containing stabilizing ingredients are produced by the hydrogen peroxide peroxidation of corresponding carboxylic acids which are not substantially soluble in water by a continuous process in which the peroxidation reaction takes place in solution in concentrated sulfuric acid, or other strong acid, while that solution is intimately interdispersed, by means of agitation, with methylene chloride, or other organic solvent, in which the re-sulting peroxycarboxylic acid is soluble, but the carboxylic acid is not, and the sulfuric acid, or other acid, is recovered from the effluent of the process by reacting it with borax and caustic soda or soda ash to form crystals of boric acid and sodium salt of the strong acid which, in admixture with peroxy-carboxylic acid recovered from the effluent, form the peroxycarboxylic acid composition product.  The meth-ylene chloride is also recovered from the effluent and recycled to the process.

Abstract: HYDRAULIC MINING OF TAR SANDS                  Abstract of the Disclosure Bitumen is separated and recovered from tar sands deposits by use of special  hydraulic mining techniques.   One or more jets  of  hydraulic mining  fluid  are  projected  by a nozzle or nozzles against a face of a tar sands deposit and advanced towards the face as the face erodes under the jetting action.  Sand and bitumen separate, due to the jetting action, and are removed from the eroding area by the flow of hydraulic fluid which  is  cycled to a  recovery zone for separation of fluid,  sand,  and  bitumen.     Fluid  is recycled,  bitumen recovered,  and sand  disposed of as  backfill.   Advance of a single nozzle is varied by lateral  diversion to erode over a wider area of the face and  increase the volume eroded by a single advancing jet.
