Abstract: A ball pickup hopper on supporting wheels has a bottom panel contoured with channels extending from a front of the hopper to the supporting wheels. Extending forward of the hopper are opposing left and a right herding rails directing balls in front of the apparatus into the channels as the apparatus is moved over a ground surface. The supporting wheels are positioned and adapted for receiving balls moving through the channels, compressively rotating and lifting the balls between the supporting wheels and the hopper, and expelling the balls into the hopper through openings. A top cover is fitted to enclose the hopper and to alternately act as a base for supporting the hopper at an appropriate height for use in ball practice.

Abstract: The present invention relates to a process for the preparation of halo-4-phenoxyquinolines.

Abstract: The present invention relates to a new improved, simplified process for the preparation of halo-4-phenoxyquinolines, whereby thionyl chloride is used as the chlorinating agent to prepare the corresponding chloroquinoline intermediate prior to the final coupling reaction, and a single, inert high boiling polyether solvent is used throughout the entire reaction procedure.

Abstract: 2-Chlorosulfonyl-5-alkoxy[1,2,4]triazolo-[1,5-c]pyrimidine compounds, such as 2-chlorosulfonyl-5-ethoxy-7-fluoro[1,2,4]triazolo[1,5-c]pyrimidine, that are useful for the preparation of 5-alkoxy[1,2,4]triazolo [1,5-c]pyrimidine-2-sulfonamide herbicides, were prepared in an improved manner from 5-alkoxy[1,2,4]triazolo [1,5-c]pyrimidine-2(3H)-thione compounds, such as 5-ethoxy-7-fluoro[1,2,4]triazolo[1,5-c]pyrimidine-2(3H)-thione, by oxidation with hydrogen peroxide to obtain novel 2,2'-dithiobis(5-alkoxy[1,2,4]triazolo[1,5-c]pyrimidine) compounds, such as 2,2'-dithiobis (5-ethoxy-7-fluoro[1,2,4]triazolo[1,5-c]pyrimidine), and subsequent chloroxidation of these intermediate compounds.
