Title: Microencapsulation of anaerobic compositions
IPC: B01J13/18
Filed: 1973-02-22
Abstract: 1411475 Microcapsules LOCTITE CORP 22 Feb 1973 [22 Feb 1972] 8688/73 Heading B8C Microcapsules having a core of a liquid "anaerobic" composition are prepared by dispersing and agitating an anaerobic composition comprising a polymerisable acrylate ester monomer and a peroxy polymerization initiator therefor as droplets in a liquid immiscible therewith, adding a first reactant which is soluble in the immiscible liquid and which is capable of being reduced to a state in which it reacts with the said peroxy initiator to generate free radicals, adding a second reactant which is a reducing agent for the first and continuing agitation until solid polymer walls have formed around the droplets the first reactant being used in an amount less than the stoichiometric amount required to react with the peroxy polymerization initiator. Numerous suitable acrylate esters are specified including di- and polyacrylates and alpha-substituted acrylates, e.g. methacrylates and chloroacrylates. Preferred peroxy initiators are organic hydroperoxides and suitable first and second reactants are reducible transition metal compounds, e.g. water-soluble salts of Fe, Cu, Co, Mu, Su, Ti, Cr and Sb, and a reducing agent therefor, e.g. anaerobic acid, oxalic acid, hydroquinone and pyrogallol, respectively. Other agents which may be present are: latent accelerators of polymerization, e.g. organic amines and sulphimides, stabilizers, e.g. quinones, thixotropic agents, adhesive agents, thickeners, plasticizers, colouring agents and dispersing agents (to assist in forming the initial emulsion).

Title: Process for the manufacture of phosphoric esters of polyhydric alcohols
IPC: C07F9/09
Filed: 1963-03-06
Abstract: Phosphoric acid esters of polyhydric alcohols are prepared by mixing the polyhydric alcohol and water with a stoichiometric quantity of an inorganic calcium oxy-compound capable of forming the calcium salt of the phosphoric acid ester and phosphorylating the resulting mixture at a temperature in the range - 10 DEG  to + 30 DEG  C. with a solution of phosphorus oxychloride in a chlorinated hydrocarbon solvent, e.g. chloroform or trichloroethylene. Specified polyhydric alcohols include sugars, sugar alcohols, dihydroxyacetone and glycerol.  Mixtures may be used.  Calcium oxide, hydroxide or carbonate may be used.  The calcium salt of the phosphate ester may be recovered by precipitation with alcohol, e.g. ethanol, followed by repeated dissolution in water and precipitation or by countercurrent extraction with an alcohol or aqueous alcohol to remove CaCl2.  The calcium salt may be converted to other salts (e.g. sodium) via the ester itself. Examples describe the phosphorylation of maltose, mannitol, sorbitol, lactose, galactose, arabinose and fructose. Mono- or di-esters may be formed.

Abstract: 590,253. Safety devices for aircraft pilots. MALCOLM, Ltd., R., and LOBELLE, M. J. O. April 12, 1945, Nos. 9153 and 32323. [Class 4] A safety device for an aircraft pilot comprises a pilot's seat mounted to slide upwardly on guide members in the aircraft, an ejecting device adapted to hold an explosive charge and connected to the seat, and a locking device which normally holds the seat in its working position but is released automatically by the gas pressure resulting from the explosion of the charge. As shown, Fig. 1, the seat 10, 11 is carried by a metal frame supporting a cross-bar 13 over which the pilot can tuck the heels of his shoes when about to operate the ejector, the frame being fitted with brackets 19, 22 and 24 in which are mounted rollers 18, 21 and 23 engaging channelled guide rails 14, 15 and 16 secured to the aircraft cabin structure. The ejector mechanism comprises telescopic cylinders, the inner cylinder being carried by a bridge 32 mounted on a cross member 30, and the head 34 of the outer cylinder 33 being connected by links 35 and 36 to frame members 37 of the seat back. In one form, Fig. 6, the inner cylinder 46 has a screwed base portion 47 mounted on a bracket 40 secured to the bridge 32. Claws 41, pivoted to the bracket 40 and engaging a ferrule 45 screwed to the lower end of cylinder 33, normally hold the seat in its working position and are connected together by lugs 44 engaging a shear pin 43 of aluminium or brass. The upper end of the cylinder 33 contains a cartridge 54 which may be fired by an electrically-operated striker 58 or by ignition leads 59 (see Fig. 8, not shown). In firing the cartridge, the gas pressure rises, the cylinder and seat are moved upwardly on the guide rails and ejected from the cockpit. The piston 48 is fitted with a flap valve 52 which is normally open to allow pressures inside and outside the cylinder to equalize during gradual changes of atmospheric pressure, but which is closed by the gas pressure as soon as the cartridge is fired. In a second form, Fig. 7, an intermediate cylinder 62 is fitted between the cylinders 46 and 33 to allow the gases produced by firing of the cartridge to act over a longer period. A thin metal thimble 64 is mounted in the cap-shaped end of the cylinder 62 to form a gas seal, and the ferrule 45 carries a metal ring 66 which absorbs shock by crushing when the cylinder 33 picks up the cylinder 62. The bracket 40 may be mounted on the bridge 32 by means of a hand-operated screw jack so that the height of the seat may be adjusted (see Fig. 9, not shown). The pilot's parachute is arranged to open automatically after ejection. The pilot may be strapped to the seat so as to descend with it, or the opening of the parachute may free the pilot from the seat so that it falls separately. Specifications 399.332 and 583.257 are referred to.
