Abstract: ABSTRACT OF THE DISCLOSURE          OPTICAL MEMORY SYSTEM HAVING IMPROVED POSITIONING AND          FOCUSING CONTROL CIRCUITRY        An optical storage system employing a laser beam which is directed and focused onto an optical disk for reading and/or writing data in a track of the disk.  Positioning control is achieved by providing for track following and track seeking using a plurality of interactive servo-loops. Proper focusing is maintained using focusing control circuitry which produces a focus error signal that is applied to a focus motor.  This focusing control circuitry is able to return the objective lens assembly to its in-focus position so long as the objective lens assembly remains within a predetermined capture range.  In the event that the objective lens assembly is outside of this capture range, a waveform generator is enabled which produces a correction signal that causes the focus motor to move the objective lens assembly back within the capture range with a velocity and for a time period sufficient to permit the focusing control circuitry to regain control and return the objective lens assembly to its in-focus position.

Abstract: DISPOSABLE CUP WITH SIDEWALL POP-OUT              ABSTRACT OF THE DISCLOSURE     A paper cup or similar disposable thin-walled fluid container with a removable or pop-out portion in its sidewall containing redemption information is dis-closed wherein the pop-out portion is formed by a series of surrounding perforations in the sidewall, which per-forations are sealed against fluid leakage by being filled with the protective material, such as wax, that is used to coat the sidewall to protect it against the fluid in the container. The perforations may outline an integral portion of the sidewall or when the redemption indicia is to be obscured,  separate portions at the opposite edges of the sidewall blank may be outlined, which portions will cooperate to form the pop-out portion as part of the sidewall seam when the edges are overlapped and joined.   In the latter instance, the perforations extend into the sidewall beyond the limits of the seam so that an opening will occur in the sidewall when the pop-out portion or a part thereof is removed to view the prize indicating indicia.

Abstract: Abstract:    A method of upgrading low-rank coal comprises the steps of dehydrating crushed low-rank coal using a rotary drum in a drying section, dry distilling the coal dehydrated in the drying section in a rotary drum in a dry distillation section and subsequently cooling the dry-distilled coal in a cooling section, while enabling the coal to adsorb tar produced from the coal in the dry-distillation section.  The present invention makes it possible to continuously upgrade large quantities of low-rank coal with a high moisture content and hence a low calorific value, to provide upgraded coal with an increased calorific value and which is not prone to spontaneous combustion.

Abstract: Improved Processing for Titanium Alloys Abstract Process for improving the crack growth behavior of titanium alloys containing substantial beta stabilizers and at least 3% molybdenum, such as Ti-6-2-4-6.  The process includes the steps of forging above the beta transus temperature, cooling at a controlled rate through the beta transus temperature, heating to a temperature between 50-150°F below the beta transus temperature, cooling the alloy at a rate in excess of that produced by air cooling, and aging the material between about 900°F and 1100°F.  The resultant material has sub-stantially improved crack growth behavior when contrasted with material processed according to the prior art.

Abstract: Title of the Invention:         METHOD OF ENCAPSULATING FINELY DIVIDED SOLID PARTICLES AND STABLE SUSPENSIONS PREPARED THEREBY          Abstract of the Disclosure:         Finely divided water insoluble solid particles free of ionic charges and ranging in size from about 0.01 to several hun-dred microns or higher, including but not limited to paint pigment particles, are given a generally uniform polymeric encapsulation by admixing such particles in an aqueous reaction medium with a water insoluble monomer polymerizable to form a generally water insoluble polymer free of ionic charges in the presence of a non-ionic surface active stabilizing agent, preferably a polyethoxy-lated alkyl phenol containing at least about eight carbon atoms in the alkyl group thereof and preferably at least about 40-50 ethylene oxide groups per molecule, and polymerization of the monomer is then initiated, usually with heating, with a redox polymerization initiating system which is free of anionic groups and does not decompose to release anionic groups in the reaction medium.  Naturally agglomerated particulate materials are effec-tively dispersed in situ during polymerization, eliminating the necessity for preliminary grinding and/or dispersion treatments.     Monomers generally useful for emulsion polymerization and free of ionic groups are effective and reaction conditions are generally the same as employed in emulsion polymerization.  The polymeriza-tion product is a suspension of generally discrete particles enveloped within a polymeric coating which exhibits remarkable stability against flocculation or settling.  White paint pigments, e.g., titanium dioxide, encapsulated in this manner exhibit greatly increased hiding power, while colored pigments exhibit greater brilliance and depth of color in dried paint films, and the film in either case has much improved abrasion or scrub resistance, and much improved stain reistance due to reduced porosity, all compared to equivalent conventional latex paints.

Additionally, the apparatus may perform error detection and burst error trapping.  The error correction apparatus of the present invention uses a common set of registers and two sets of fixed field multipliers to perform all specified error correction functions.  The organization of the registers and multipliers is controlled by two sets of multiplexers under control of a controller.  The function of the apparatus is programmed by the microprocessor via its control of the controller.
