Abstract: 694,257. Controlling aircraft. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 18, 1952. [April 18, 1951] No. 9100/51. Class 4. [Also in Group XXIX] A venting valve in a line leading from a pump to a jack acting on the pilot's control column restricts the hydraulic flow line passing from an inlet 20 to an outlet 23 when subject to an acceleration, and the valve is made up of two parts 13. 18 so that, in the event of part 13 sticking in the How restricting position shown, the other part 18 will be able to move relatively to part 13 into the dotted-line position and open an alternative passage 20, 17, 15, 23. In normal flight, with valve 13 open, the pump output flows from 20 to 22 and so to a sump, but when a dangerous acceleration takes place, the masses 13, 18 move to close valve 13 on to its seat 12 and allow pressure to build up in the jack, which latter will move the control column to a position producing ''negative acceleration". On return to normal flight, both masses 13, 18 should move to free the passage leading from 20 to 22. Valve 13 can be released manually when stuck in the flow restricting position by means of a  lever 24 and push rod 27.

Title: Method for the polymerization of rosin and its esters
IPC: C09F1/00
Filed: 1941-07-18
Abstract: 556,392. Polymerized rosin and rosin esters. HERCULES POWDER CO. July 18, 1941, No. 9125. Convention date, Feb. 21. [Class 2 (iii)] Rosin or a rosin ester is polymerized by treating a solution thereof, in a petroleum hydrocarbon solvent having an end boiling point not above 60‹ C. and selected from the group consisting of propane, butanes, pentanes and hexanes, with sulphuric acid or an organicsubstituted sulphuric acid. The normally gaseous paraffin hydrocarbons, such as propane, / N-butane and isobutane, may be used as the solvent at sufficiently low temperatures, or under sufficiently elevated pressure, to keep them in liquid form. A preferred solvent is a petroleum ether boiling completely within the range 30‹ C.-60‹ C. and at least 90 per cent. of which boils below 50‹ C. and at least 10 per cent. of which boils between 30‹ C. and 35‹ C. The preferred polymerization catalyst is 80- 85 per cent. sulphuric acid, but sulphuric acid of other strengths may be used, as well as organic substituted sulphuric acids such as monoethyl sulphuric acid and monoacetyl sulphuric acid. The rosin or rosin ester is dissolved to form a solution of from about 10 per cent. to 75 per cent. by weight, and the sulphuric acid is added. The temperature is preferably maintained at not above 35‹ C., and this control may be effected by allowing the heat of reaction to volatilize a portion of the solvent. The process is applicable to wood rosin or gum rosin, to the equivalent acids such as abietic or sapinic acid, and to esters of rosin with glycol, glycerine, pentaerythritol, diethyleneglycol, diglycerol, methyl alcohol, ethyl alcohol, propyl alcohol or benzyl alcohol. At the end of the reaction, sludge is separated and the solution phase is washed and evaporated to recover the product. Examples are given. Specification 459,320 is referred to.
