Title: Improvements in or relating to a process of making synthetic resins and the productsresulting therefrom
IPC: C08G8/00
Filed: 1950-10-19
Abstract: A synthetic resin is made by etherifying at least one phenolic hydroxyl group of a natural catechol tanning agent with mono-chloro- or mono-bromoacetic or propionic acid, by reaction in an alkaline medium with not more than 2 mols. of the acid per mol. of tanning agent and etherifying at least one of the remaining phenolic hydroxyl groups by reaction with an aralkyl halide in an alkaline aqueous medium.  The products are soluble in organic solvents such as mixtures of benzene or toluene and methyl or ethyl alcohol.  In the example, quebracho extract is reacted with monochloracetic acid in the presence of caustic soda, and the resulting product is reacted with benzyl chloride; the product is poured and allowed to solidify in a tray, the resulting soapy mass being added to cold aqueous hydrochloric acid and the resin removed by filtration.  The final product is considered to be a quebrachomonocarboxymethyl dibenzyl- or -di(carboxymethyl) monobenzyl-tri-ether according to the molar proportions of the reactants employed.  The products may be used in compositions for coating leather, cloth and paper.ALSO:A synthetic resin is made by etherifying at least one phenolic hydroxyl group of a natural catechol tanning agent with mono-chloro- or mono-bromo-acetic or propionic acid by reaction in p  an alkaline medium with not more than 2 mols. of the acid per mol. of tanning agent, and etherifying at least one of the remaining phenolic hydroxyl groups by reaction with an aralkyl halide in an alkaline aqueous medium.

Title: Improvements in and relating to cam drives
IPC: F16H53/02
Filed: 1930-08-27
Abstract: 343,420. Cams. JUNKERS, H., 21, Kaiserplatz, Dessau, Anhalt, Germany. Aug. 27, 1930, No. 25591. Convention date, Aug. 29, 1929. [Class 80 (iii).] The diameter d of a boss 3 on to which the roller follower 4 of a cam 2 is moved during periods of rest is approximately equal to the sum of the maximum and minimum radii of the cam ; and the transition surfaces 5, between cam and boss are conical with the opposite directed apices 7, 8 of the cones lying on the shaft axis. By these means a minimum sliding distance for a given inclination of the transition surface is obtained and the radial displacement of the follower due to rotation of the cam is reduced to a minimum whereby the resistance to lateral displacement depends almost entirely on forces occurring during rest and not on acceleration or driving forces such as occur in fuel pumps. In one form a cam is arranged on each side of the boss and in a known arrangement also shown the boss diameter is twice the minimum cam radius and the transition surface diminishes gradually in cross-section towards the boss.

Patent GB-206133-A (GB)
Title: Process for manufacturing a perylene vat dye
IPC: C09B3/20
Filed: 1923-10-15
Abstract: Perylene vat dyes are produced by treating perylene quinone with chlorine.  A chlorine addition product is first formed, which, on treatment with agents fixing hydrochloric acid, is transformed into a chloroperylene quinone.  According to the examples, (1) a suspension of perylene quinone in nitrobenzene is heated with chlorine in the presence of a trace of iodine; the chlorine addition product formed is precipitated by the addition of light petroleum and is recrystallized from nitrobenzene; (2) the chlorine addition product of the preceding example, dissolved if desired in nitrobenzene, is boiled with aniline; on cooling, chloroperylene quinone separates out; it dyes cotton greenish yellow from a cherry red vat.  The colours obtained by the use of the chlorine addition product are not so fast towards chemical reagents as those of the chloroperylene quinone.

Patent GB-799385-A (GB)
Title: The production of boron
IPC: C01B35/02
Filed: 1956-08-27
Abstract: Boron and zinc chloride, bromide, or iodide, are produced by the interaction of zinc and the appropriate boron halide.  The boron halide is injected into the reaction chamber in vapour form while the zinc is injected in vapour form or in finely divided liquid or solid form.  Finely divided solid zinc may be injected as a suspension in an inert gas.  The vaporous boron halide is injected first so as to remove air.  The reaction chamber, which may be of quartz, is preferably heated above 907 DEG  C., e.g. at 950 DEG  C.  The reaction pressure may be at, above, or below atmospheric pressure. Solid boron, which deposits during the reaction on the walls of the chamber and a baffle located at the exit thereof, is removed after the chamber has been allowed to cool.  Vaporous zinc chloride and unreacted zinc and boron halide may be separately condensed, or only the zinc chloride condensed.  In either case, the unreacted zinc and boron halide may be returned to the process.  The zinc halide may be used in the production of further zinc and boron halide.
