Methods and systems for packaging a plurality of objects are disclosed. The system includes a base tray having a first end and a second end, an object reservoir positioned at the first end, a dispensing guide positioned at the second end, and a column guide disposed between the reservoir and the dispensing guide. The column guide is configured to convey objects from the reservoir to the dispensing guide using gravitational forces via a plurality of longitudinally extending guiding columns. A tilt tray having a front edge and a back edge is positioned above the column guide. The tilt tray has a front edge and a back edge, and is anchored to pivot between a forward-engaged position and a backward-engaged position. When the tilt tray is in the backward-engaged position, the back edge is positioned to prevent object movement along the column guide, while the front edge is positioned to allow object movement along the column guide and into the dispensing guide. When the tilt tray is in the forward-engaged position, the front edge is positioned to prevent object movement along the column guide and into the dispensing guide, while the back edge is positioned to allow objects to pass underneath the back edge. The system is sized and configured for packaging golf balls in interchangeable object containers.

The present invention generally relates to processes for recovery of phosphorus values and salt impurities from aqueous waste streams. In particular, the present invention relates to processes for recovery of phosphorus values and salt impurities from aqueous waste streams generated in the manufacture of phospho-herbicides, including N-(phosphonomethyl)glycine and glufosinate.

Recovery of phosphorus values and salt impurities from aqueous waste streams

This invention relates to the preparation of N-(phosphonomethyl)glycine ('glyphosate') from N-(phosphonomethyl)iminodiacetic acid ('PMIDA'), and more particularly to methods for control of the conversion of PMIDA, for the identification of reaction end points relating to PMIDA conversion and the preparation of glyphosate products having controlled PMIDA content.

Control of N-(phosphonomethyl)iminodiacetic acid conversion in manufacture of glyphosate

A method is described for making solution stable salts of iminodiacetic acid (IDA), useful as precursors in the manufacture of N-phosphonomethylglycine. Concentrated dialkali salts of IDA which are insoluble at temperatures below about 55.degree. C., such as the disodium salt (DSIDA) are acidified to monoalkali salts, such as monosodium IDA (MSIDA). The resulting salts are stable in solution, and may conveniently be stored or transported in solution without recourse to dilution, heating, or similar measures.

Use of monosodium iminodiacetic acid solutions in the preparation of

A process for preparing glyphosate and other secondary amines of related structure in which a precursor primary amine such as aminomethylphosphonic acid is condensed with glyoxylic acid, or a related aldehyde compound, and the condensation product reduced without isolation to produce the desired product.

Process for the preparation of glyphosate and glyphosate derivatives

A process is provided for destroying formic acid and/or formaldehyde in an aqueous, organic acid waste stream by contacting the stream with a supported precious metal catalyst and passing air or molecular oxygen gas through the solution to promote chemical oxidation. The invention is a safe, practical and cost-effective alternative to bio-system treatment of these compounds using microorganisms. The process of the invention may be practiced in either a batch or continuous mode and, in accordance with the invention, formic acid present in a stream at a level of 3800 ppm and formaldehyde present in an amount of 5800 ppm can be reduced respectively to levels of 200 ppm or less.

Formic acid and formaldehyde destruction in waste streams

N-Phosphonomethylglycine can be purified and concentrated from aqueous solutions containing N-phosphonomethylglycine and impurities, such as N-formyl-N-phosphonomethylglycine, phosphorous acid, and the like, by passing the aqueous solution through an ion exchange column containing a weakly basic ion exchange resin to remove such impurities.

Process for purifying N-phosphonomethylglycine

The invention disclosed herein relates to a process for producing heterocyclic ethanolamines, especially 2-(2-furyl)ethanolamine.

Process for the preparation of 2-(2-furyl)ethanol amine

N-phosphonomethyl glycine is produced by the strong acid catalyzed hydrolysis of N-(phosphonomethyl) imino-diacetic acid. N-phosphonomethyl glycine is useful as a post-emergent herbicide.
