Abstract: The invention is a choline feed stock precursor having greater than about 80-wt % of choline chloride, a lubricating agent, and an excipient. Generally, the composition of the invention may comprise a choline compound at concentrations above 80 wt-%, trace amounts of lubricating agent, and an excipient. To extend shelf-life, a hydrophobic stabilizing agent or adjuvant may be added to the composition of the invention. This preferred composition remains free-flowing when subjected to ambient conditions of up to 49.degree. C. and less than 90% relative humidity. The invention is also a process for formulating choline feed stock precursors, having greater than about 80-wt % choline chloride. The method of the invention generally includes the steps of inter-mixing choline and an excipient, spray drying this mixture in the presence of a lubricating agent and adding an additional portion of hydrophobic stabilizing agent, to the mixture.

Abstract: There is disclosed herein an apparatus adapted for use on a conventional four slide machine which allows one or more end portions of a length of stock to be threaded simultaneously with the forming of another portion of the stock to a desired contour. The apparatus includes a thread rolling head driven by a motor, both of which are secured to a compound slide which is mounted on a four slide machine and adapted to be reciprocated through the agency of a cam and cam follower arrangement provided on the four slide machine.
