Abstract: A device for termination of synthetic rope, with an eye socket substantially free of sharp edges, a bale at the top of the eye socket with an eye for attachment of connecting links, a groove for receiving synthetic rope. In addition, the device includes a bale with extended sides at the top of the eye socket, a thimble within a synthetic rope eye contained within the extended sides and restrained from translation by pin. A shroud is also provided for protection at the bottom of the eye socket at the synthetic rope splice. The device is intended to aid in the efficient and safe connections to other objects such as other synthetic mooring lines, steel wire rope, and anchor chains.

Abstract: The detachable ears rope thimble comprised of thimble body, detachable ears and having the optional features of bale, main load pin sub assembly, and a restraning load sub assembly. The inventive thimble provides very high load capacity ability for wire or synthetic ropes. Furthermore the thimble assembly enables eye splicing on new ropes yet allows for the thimble addition to previously formed eyes without resplicing the eyes. The invention provides a thimble that fully contains even the oversize found in fresh synthetic ropes protecting them within an array of detachable ears from abrasion. The outer body has smooth form with embedded detachable ears and rounded edges preventing synthetic fiber damage.

Abstract: A detachable synthetic rope connector with connector body, bale, main load pin sub assembly, and a restraining load sub assembly that permits the use of large diameter synthetic and other mooring components such as cable and chain on offshore work vessels without specialized deck equipment. The inventive connector allows for safe and redundant restraint of a mooring segment in order to provide transfer of the tension load while providing connection features that simplify separation and the reduction of safety risks to vessel working personnel and the environment, and the features allow for the connector to be separated easily while the portion holding the rope is restrained while the bale can be removed.

Abstract: The invention is a user control panel for a pitching system with a pitching mechanism. The control panel allows a user to separately control ball speed and tilt angle. The control panel also displays an estimated height at which the ball will cross the plate for the selected ball speed and tilt angle. In the preferred embodiment, a vertical row of lamps shows the estimated ball height. The control panel can include symbology to indicate strike zones for batters of different heights.

Abstract: The invention is a pitching system with a pitching mechanism. A control panel allows a user to separately control ball speed and tilt angle. The control panel also displays an estimated height at which the ball will cross the plate for the selected ball speed and tilt angle. In the preferred embodiment, a vertical row of lamps shows the estimated ball height. The control panel can include symbology to indicate strike zones for batters of different heights. To operate the batting cage, the batter selects the desired ball speed. The control panel displays an estimated ball height based on the selected ball speed and current tilt angle. The batter then adjusts the tilt angle of the pitching mechanism until a desired ball height is reached. The batter then starts the machine. In this manner, the batter avoids wasting balls selecting a preferred choice of ball speed and height. The batter can also change ball speed and tilt angle during a pitching sequence, to alter the strike zone through which balls are pitched.

Abstract: A process is provided for purifying phosphoric acid, such as wet process phosphoric acid by extracting the impure phosphoric acid with a nonaqueous solvent and contacting the nonaqueous solution of phosphoric acid with a strongly basic anion exchange resin and recovering the purified phosphoric acid by stripping the nonaqueous solution with an aqueous solution.

Abstract: Phosphoric acid is treated to remove and/or tie up heavy metals and antimony to enable the acid to be used in electrical semiconductor applications by reacting the acid with hydrogen sulfide and with hydrogen peroxide in separate treating steps. The hydrogen sulfide precipitates metal sulfides which are separated from the acid, and the hydrogen peroxide oxidizes dissolved antimony so that it is tied up and does not post-precipitate in the acid after removal of the metal sulfides.

Abstract: Phosphorus values in the raffinate from wet acid purification and nodule fines from an electric phosphorus furnace are recovered as elemental phosphorus by forming briquettes with a bed of the raffinate and nodule fines, curing the briquettes and feeding the cured briquettes plus the requisite coke and silica fluxing agent into an electric phosphorus furnace.

Abstract: The invention is a process to purify a solution of phosphoric acid by removing transition metal impurities such as iron, chromium and vanadium. In the process a solution of phosphoric acid in an organic solvent which is substantially immiscible with water is contacted with an aqueous solution of a salt of an alkali metal of phosphoric acid. The phosphoric acid recovered following the contacting contains a substantially lesser content of transition metal impurities.

Abstract: Alkali metal phosphates are recovered from a water immiscible solvent solution of aqueous wet process phosphoric acid by neutralizing the acid with a basic alkali metal salt in a ratio of alkali metal to phosphorus of 1 to 3.5 to form at least the mono alkali metal phosphate. The solvent is given a water wash to recover entrained alkali metal phosphates. The resulting aqueous solution aforesaid and wash liquor containing the alkali metal salts are separated from the stripped solvent.

Abstract: In the process of purifying yellow phosphorus by treating liquid yellow phosphorus with active carbon and separating the purified phosphorus from the spent active carbon containing adhering phosphorus, the spent active carbon is mixed with sufficient liquid phosphorus to form a slurry which is pumped to a disposal zone. The disposal zone is preferably a phosphorus furnace.

Abstract: Either commercial yellow phosphorus or a phosphorus sludge is reacted with a slurry of calcium hydroxide in aqueous sodium hydroxide to form a sodium hypophosphite solution containing calcium and hydroxide ions. The solution is neutralized with phosphoric acid or an acid phosphate salt with the co-production of an insoluble calcium phosphate. The neutral solution is contacted with an ion exchange resin charged with sodium ions to remove any remaining calcium ions.

Abstract: Anhydrous cyanuric acid containing amounts of occluded solvent is recrystallized to a purified cyanuric acid dihydrate by slurrying the contaminated anhydrous cyanuric acid in an aqueous medium.

Abstract: Strong, stable, free-flowing agglomerates of sodium carbonate peroxide are produced by contacting rotary agitated sodium carbonate peroxide with an aqueous agglomerating solution having a viscosity of at least 30 centipoise and containing less than 20% by weight agglomerating agent.

Abstract: A process for the production of sodium and potassium peroxydisulfates by continuously reacting a 10 to 75 weight percent solution of the corresponding sodium or potassium hydroxide with a 20 to 70 weight percent solution or slurry of ammonium peroxydisulfate, at a temperature between 15.degree. and 45.degree.C and at a pH between 11 and 13. Air or an inert gas is passed through the reaction medium to remove ammonia and the product is recovered by conventional means, preferably by spray drying.
