Patent GB-346822-A (GB)
Title: Process for the preparation of ketones
IPC: C07C45/54
Filed: 1930-01-16
Abstract: Higher homologues of acetone are obtained by heating alkaline earth salts of higher fatty acids such as calcium butyrate mixed with calcium oxide or hydrate, while stirring the mass.  The addition of calcium oxide or hydrate, which may be about 10-30 per cent by weight of the salt of the fatty acid, serves to lower the melting point of the mixture and permit the ketone vapours produced to escape more readily; when commercial fatty acid salts obtained by fermentation are employed, it also combines with the nitrogen- and sulphur containing impurities therein.  In addition, the mixture may contain an inert solid diluent such as sand.  The distillation may, in the case of calcium butyrate, be carried out at temperatures of about 300 DEG  C., and in the presence of a continuous flow of an inert gas, or preferably of a condensible vapour such as superheated steam.  When it is desired to obtain methylalkyl mixed ketones, an amount of calcium acetate preferably not exceeding one-third of the weight of the other fatty-acid salt may be added to the mixture to be heated.

Patent GB-353389-A (GB)
Title: Improved process for solubilising gums, resins, copal gums and the like
IPC: C09F1/00
Filed: 1930-01-16
Abstract: Insoluble or difficulty soluble gums and resins, particularly for use in oil, spirit or nitrocellulose varnishes, are rendered soluble by heating them, preferably in a finely divided condition, in the presence of oxygen or oxygen-containing gases such as air. The heating is effected at a comparatively low temperature, such that substantial decomposition does not occur, for an extended period. The process is particularly directed to solubilizing copals such as amber or the Congo, Hard Manila, Sierra-Leone, Zanzibar, Pontianac or Kauri varieties.  The process may be accelerated by carrying it out in damp air, or by simultaneous use of to ultra violet rays. Previous neutralization of free resin acids result in products soluble in drying oils such as linseed or wood oil.  The products are soluble in alcohols and esters &c.  In examples (1) Congo copal is finely ground and exposed as a thin layer in a room, where it is heated to 45--50 DEG  C. for 3--4 days. The air temperature is then increased to 65 DEG  C. for 5--6 days. The product forms a clear solution in alcohol which contains 75 per cent of resin.  (2) Zanzibar copal is exposed as in the first example, but the humidity of the air is kept just below saturation point, the resin also being exposed to the rays of a mercury vapour lamp.  After 4 days' treatment at 65--70 DEG  C. an easily soluble product is obtained.

Title: Fuel tank inerting
IPC: B64D37/32
Filed: 1972-01-13
Abstract: 1331736 Minimising explosion risk in aircraft fuel tanks PARKER-HANNIFIN CORP 13 Jan 1972 [29 Jan 1971] 1708/72 Heading ASA An aircraft fuel tank inerting system involves mixing the liquid fuel being supplied to the tank with inert gas from the tank vapour space in order to scrub dissolved oxygen from the fuel; the tank includes vent means from the vapour space and also includes means for further scrubbing of oxygen from the fuel during ascent and for pressurising the tank with inert gas during descent. Tank 1 with ullage 2 is supplied via line 3 and nozzle 4 with N 2  from liquid source 5, under the control of valve 6 operated by differential pressure sensing device 7. Valve 6 opens when the pressure difference between the tank and atmosphere drops below a predetermined minimum. The tank also has vent valve 8, and fuel inlet valve 9 coupled to nozzle 10. Valve 9 leads fuel into aspirator 12, Fig. 2, which has suction port 14 to which tube 15, extending into the tank vapour space, is connected. The negative pressure thus produced at throat 16 of venturi nozzle 17 sucks inert gas from space 2 to mix with the fuel. The mixture passes through section 18 and tube 20, and inert gas and liberated O 2  bubble therefrom through tank 1 to ullage 2. During flight, pump 21 circulates the fuel through scrubbing tube 22, to which N 2  is injected at elbow 25. The N 2  line 26 includes regulator valve 27 and check valve 28 to prevent entry of fuel. Electrical control 30 is connected to valve 27 and pump 21 to activate and de-activate them. The outlet of tube 22 is near the fuel surface and remote from pump 21 to ensure maximum circulation. The system acts to maintain the oxygen content of the ullage gas always below 10%.
Patent GB-1012571-A (GB)
Title: Improvements in or relating to safety devices for filters
IPC: B01D35/143
Filed: 1963-01-15
Abstract: 1,012,571. Oil filter safety device. G. MOATTI. Jan. 15, 1963 [Jan. 19, 1962; May 17, 1962], No. 1760/63. Heading B1D. A safety device operative upon the clogging of an oil filter has first and second elements subjected to the pressures obtaining at the inlet and at the outlet of the filter respectively, connecting means between said elements, spring means acting on the said connecting means so as to balance the differential pressure up to a predetermined safe value, and a contactor actuated by the above mentioned connecting means when the pressure difference across the filter exceeds said predetermined safe value due to an advanced clogging of the filter and thereby closing the circuit of the warning device whilst optionally effecting the opening of an electrically-controlled by-pass valve. In Fig. 1, the elements are the diaphragms 24 and 27. Duct 5 is connected to the inlet and duct 6 to the outlet of the filter, so that the inlet pressure is acting on diaphragm 24 and the outlet pressure on diaphgram 27. Spring 19 is adjusted by means of the thrust fixture 20, 21 and nut 22 so as to balance the normal inlet pressure and thus maintain rod 14 and heads 15, 16 and 17 in the position shown. As the filter becomes clogged, the pressure increases in chamber 2 and decreases in chamber 3 until the pressure in chamber 2 overcomes the action of the spring 19, so that the head 16, 17 is pushed to the left, as does head 15, drawn by rod 14, so that rod 30 moves away from the contactor 31 which closes, lighting lamp 32 and optionally effecting the opening of electrically-operated by-pass valve 34. In a variant, rod 30 is eliminated and the unit 20, 21 is hollow, enclosing a rod 35 (chain-dotted line). Contactor 31 is replaced by contactor 31<SP>1</SP> which is normally out of contact with the rod 35 but which is contacted as rod 14 moves to the left, so actuating the warning device. In Fig. 2, spring 19a rests against thrust collar 20a pierced by a central hole for a rod 14a connected to diaphragms 24a and 27a as in Fig. 1. The part situated between the diaphragms is hollowed-out to accommodate a contactor 31a actuated by a projection 36 or 36<SP>1</SP> carried by the rod 14a. In Figs. 3 and 4, levers 41, 41d are used to amplify the movement of the diaphragms 24c, 27c and 24d, 27d. In Figs. 2, 3 and 4, pistons fitted with rings or toroidal gaskets may replace the diaphragms. In Fig. 6, pistons 50, 54 having toroidal gaskets 49, 53 are used. If desired, the length of the body 1 or If may be reduced and the depth of the cups 8, 9 or 8, 9f increased, especially where toroidal gaskets are used, ducts 5 and 6 being arranged in the cups instead of in the body of the appliance. Specifications 833,395 and 904,983 are referred to.
