Abstract: 583,902. Inertia switches. HOLMES, E. L., HUGHES, A. J., and HUGHES & SON, Ltd., H. April 22, 1944, No. 7522. [Class 38 (v)] [Also in Group XX] A switch for breaking the circuit to an electromagnetically operating gravitational control for a gyroscope when the acceleration exceeds a predetermined amount comprises a lever h, pivoted at 3, eccentrically weighted at f, and urged by a spring g against a stop l, which holds the lever at a predetermined angle, e.g., 10‹, to a normally horizontal part 5-6 of the gyroscope. The tension of the spring g is adjusted to just hold the lever against the stop I and thus keep the circuit closed when the lever h is horizontal, i.e., when the weight f is exerting its maximum leverage, so that the lever h is only moved from the stop l to break the circuit when the horizontal acceleration exceeds an amount determined by the angle between h and 5-6.

Title: Process for the manufacture of a dicarboxylic acid
IPC: C07C51/27
Filed: 1948-03-12
Abstract: In the manufacture of ethylene-bis-glycollic acid by nitric acid oxidation of triethylene glycol, the glycol is added gradually to the nitric acid at 40-90 DEG  C.  The oxidation is preferably carried out in the presence of a vanadium compound, e.g. 0-1 per cent of ammonium vanadate, and the nitric acid may contain sulphuric acid.  Nitric acid of higher strength than that originally present (and likewise optionally containing sulphuric acid) may be added gradually to replace the acid consumed in the oxidation, and the process may be operated in batchwise or continuous manner.  A detailed example is given and includes a description of the S-benzylthiouranium salt of the product.

Abstract: 890,010. Applying rapid-setting cement. AEROCEM Ltd. June 9, 1958 [March 8, 1957], No. 7749/57. Classes 20(2) and 20(4) In a method of applying a previously formed rapid-setting aerated cementitious mix which is ejected under pressure from a discharge device, a setting accelerator, e.g. a 40 % aqueous solution of sodium silicate, is introduced into the mix, whilst it is in or at the point of discharge of the device to effect a substantially uniform admixture thereof with said mix. The aerated cementitious mix may be prepared as disclosed in Specifications 616,207 and 652,705 and mixed by using a mixing device as described in Specification 695,111. The discharge device may be either a spray gun or an injection lance. A prepared aerated mix is discharged from a pressure vessel by air pressure or by pump to the discharge device into which the setting accelerator is fed through a separate pipe by pump pressure or gravity feed at or near to the point of discharge. In another embodiment an injection lance has a tube for the introduction of the setting accelerator terminating in the body at a point near to the tip of the lance and a supply of secondary air is introduced through a number of auxiliary air inlets disposed between the tip of the lance and the tube.

Abstract: 1,237,015. Cooling electrical components. GENERAL ELECTRIC CO. 13 Feb., 1969 [19 Feb., 1968], No. 7973/69. Heading F4U. A vapour-cooled electronics enclosure 2 provided with cooling fins 4, 5, 6 on its exterior surfaces contains a plurality of heat-generating electronic components 19 immersed in a vaporizable heat exchange liquid 12 partially filling the enclosure 2. Packages 10, 11 of electronic components requiring little or no cooling are suspended from a cover member 7 which comprises two removable sections 7a, 7b. The arrangement is such that when the enclosure is tipped, the progressive immersion of the packages 10, 11 modifies the liquid level and permits the amount of tipping to be increased without exposing the heat-generating electronic components 19 above the liquid. The heatgenerating components 19 are suspended from mounting members 14 to expose all their surfaces to the heat exchange liquid. In operation a continuous heat transfer cycle is set up in which heat from the heat generating components 19 causes the liquid to boil; the liquid vapours formed rise and condense on the interior walls of the enclosure and the condensed liquid then falls back downwardly to rejoin the liquid 12. The mounting members, shown to be horizontal, may alternatively be positioned vertically (Fig. 3) adjacent a side wall of the container 2. The heat exchange liquid may be a dielectric refrigerant such as a fluorinated hydrocarbon or methylene chloride.

Title: Improvements in or relating to the production of organic esters of cellulose
IPC: C08B3/16
Filed: 1940-05-09
Abstract: 543,311. Cellulose esters. DREYFUS, H. May 9, 1940, No. 8336. [Class 2 (ii)] A mixed ester of cellulose is obtained by subjecting a lower aliphatic ester of cellulose - to the action of an anhydride of a higher aliphatic acid in the presence of dissolved metal halide as catalyst and in a liquid medium which is a solvent for the catalyst and which has a swelling or solvent action on the lower aliphatic ester. The lower ester may be a cellulose acetate, propionate, butyrate, or cellulose ester of another aliphatic acid containing less than six carbon atoms. The higher aliphatic acid may be lauric, oleic, palmitic, stearic, or other acid containing at least 6 carbon atoms. The metal halide catalyst' may be ferric, stannic, or zinc chloride. Hydrohalide acid may also be present during esterification. The solvent liquid may be a halogenated hydrocarbon, e.g. ethylene dichloride, in admixture with acetone. Esterification may be effected at raised temperature. On completion of the reaction, the cellulose ester, if in solution, may be precipitated by mixing the solution with alcohol or other non-solvent. If desired, the ester may be precipitated by mixing the solution with hot water so as to drive off the ethylene chloride in the form of vapour. The mixed esters produced may be used for the production of artificial filaments, foils, and films. Specifications 308,323 and 312,096, [both in Class 2 (ii)], are referred to.
