Patent GB-556830-A (GB)
Title: Improvements in the manufacture of dipentaerythritol esters
IPC: C11C3/04
Filed: 1942-02-10
Abstract: 556,830. Polishing compositions. AMERICAN CYANAMID CO. Feb. 10, 1942, No. 1749. Convention date, Feb. 11, 1941. [Class 95] [Also in Group IV] Dipentaerythritol esters are produced by heating dipentaerythritol with triglyceride fats or oils, and continuously removing the liberated glycerol from the reaction mixture. Some etherification of the dipentaerythritol and glycerol may occur. Any triglyceride oil may be used including drying and semi-drying, oils, many of which are mentioned. The products when drying and semi-drying oils are used have improved drying properties; when non-drying oils are used the products are softer, but may be used in compositions such as floor and shoe polishes. The reaction may be effected in an inert atmosphere such as carbon dioxide or nitrogen, and when drying oils are used alkaline catalysts such as alkali hydroxides, carbonates, phosphates and silicates, calcium oxide and acetate and lead oxide may be used to shorten the reaction in order to avoid polymerization. The liberated glycerol may be removed by a stream of inert gas or by vacuum distillation. Examples describe the reaction of dipentaerythritol with soya, cottonseed, and linseed oils, carbon dioxide being blown through the reaction mixture in each case to remove the glycerol. Specification 556,829 is referred to.
Patent GB-637490-A (GB)
Title: Improved gear-wheel grinding-machine
IPC: B23F5/06
Filed: 1948-01-20
Abstract: 637,490. Gear-cutting. AEPPLI, A. Jan. 20, 1948, No. 1759. Convention date, Jan. 25, 1947. [Class 83 (iii)] [Also in Group XXIV] In a machine for generating gear-wheels by means of narrow-rimmed disc-like grinding- wheels 7, wherein the rolling movement is slow and the feed in the direction of the teeth is fast, the plane of each disc is slightly inclined to the direction of feed movement, and the spatial position of the feed-stroke is continuously displaced along the teeth in dependency on the rolling movement so that a strip of the entire length of the tooth-flank is ground in one feed-stroke. The slight inclination of each disc results in single-point contact between the disc and the tooth-flank and, according to the position of the path of the contact-point along the tooth-flank, so the actual path of the feed-stroke of the wheel is altered to ensure that minimum travel of the disc is required. In Fig. 9, the gear-wheel 6 is reciprocated past the discs 7 by a lever 10 actuated by a crank 14 and flexiblebands 12. The spatial position of the feed-path is adjusted by a cam 18 which is rotated by worm-gearing 19 and gradually alters the position of the crank 14 which is mounted, with its driving-motor, on a lever 15. The grinding- discs are carried on standards 21 secured to carriages 22 which are rectilinearly displaceable on sub-carriages 23 and are attached by flexible bands 25 to a central stationary cylinder 24. The sub-carriages 23 are rolled about the centre M by a fluid-operated rack 28 working through pinions 29, 27 and a rack 26 fast with each carriage 23, thus rolling the discs past the non-rotating gear 26 which is indexed after a rolling motion is completed. Bevelgearing 32, 33 rotates the worm-gearing 19, thus moving the path of the feed-stroke of the gear in dependency on the rolling-motion. The cam 18 may be theoretically exact or a straightline approximation. In a modification, Fig. 12, the spatial movement of the feed-stroke of the gear 106 is approximate, being effected by a sliding pin 142 which rotates a differential gear 145-147, to modify the position of reversal of a hydraulic valve 155. This latter valve controls the movements of a hydraulic piston reciprocating the gear-carriage 108 which is formed with a rack co-operating with a pinion on the end of a shaft carrying the valve-control disc 157. The feed-path may also be adjusted by mechanical stops or by movement of a switch controlling the reversal of a motor driving a feed-screw. Specification 15617/13, [Class 60], is referred to.

Title: Improvements in or relating to the recovery of trimethyl borate
Inventor: TULLY THOMAS JAMES
IPC: C07F5/04
Filed: 1959-01-21
Abstract: The trimethyl borate content of trimethyl borate-methanol solutions is increased by intimately admixing a solution consisting essentially of methanol and trimethyl borate with a mineral oil in an amount in excess of the solubility limit of said mineral oil in said solution to yield a mixture which breaks into two phases and recovering methanol and trimethyl borate from the oil-rich phase in which the proportion of trimethyl borate to methanol is greater than that in the original solution.  The methanol and trimethyl borate may be obtained from the oil-rich phase by fractional distillation, separating a first fraction consisting of methanol-borate azeotrope and a second fraction of higher boiling range and consisting of substantially pure trimethyl borate.  Preferably the proportion of trimethyl borate in the starting mixture should not exceed that which forms an azeotrope with the methanol and solutions containing more trimethyl borate than the azeotrope are preferably fractionated to recover as much trimethyl borate as possible leaving the azeotrope to be treated by the above process.
