Title: Improvements relating to ejectable seats for aircraft
Inventor: LOBELLE MARCEL JULES ODILON
IPC: B64D25/10
Filed: 1951-06-04
Abstract: 709,736. Escape apparatus for aircraft. M.L. AVIATION CO., Ltd. May 29,1952 [June 4,1951 July 2, 1951], Nos. 13225/51 and 15677/51. Class 4 An aircraft is provided with ejection apparatus in which a cover in the roof of the aircraft is automatically opened and the airman is ejected at a low velocity sufficient to throw him clear of the aircraft. The apparatus comprises seat ejecting mechanism in which a cartridge is fired automatically either by one of a number of immersion switches in the aircraft or by an inertia switch and a gravity actuated switch may be included so that the ejecting mechanism is immobilized in the event of an inverted crash-landing. The ejecting mechanism has a main breech 33 for a cartridge giving normal high velocity ejection under airborne conditions and an auxiliary breech 34 for a smaller cartridge for use during a crash landing on earth or under water. The breech 33 is in communication with an exhaust port 60 and a port 65 leading to the cylinders 36. The breech 34 also has an exhaust port 25 and a port 40 which leads to the cylinders. Flap valves 37, 61 and 63 of the type described in Specification 716,608 are used either to place both breeches in communication with the appropriate exhaust ports or to connect one breech only with the cylinders. The operation of the valves 61, 63 forms part of a manually operated firing mechanism for the main cartridge, the spindle 62 of valve 61 carrying a crank and pin (not shown) which engages in a cam slot of an actuating plate which is fast with a spindle 73 and during its initial movement turns the valve 61 away from port 65 and into contact with the exhaust port 60 and during its final movement actuates a firing pin, Fig. 5 (not shown), for the cartridge. Simultaneous movement of the valve 63 with valve 61 is achieved by connecting a crank 85 on the spindle 73 with a further crank 91 on the spindle 64 of the valve 63 by means of a spring loaded rod 87, the valve being snapped into either of its two positions by a toggle arm 92. The valve 37 is moved from the port 40 to the exhaust port 25 by a solenoid (not shown) energized automatically by an immersion or an inertia switch as a stage in a sequence of electrically controlled operations which first causes the jettisoning of a cockpit canopy and the retraction of a gun sight and finally fires the cartridge in the breech 34. The first Provisional Specification states that during a crash landing the seat may be ejected by compressed air or hydraulic or spring stored energy or a large cartridge may have part of its gases dissipated through an exhaust port to reduce the speed of ejection of the seat and the canopy, instead of being jettisoned, may be shattered by explosive tapes. The second Provisional Specification refers also to the provision of a manually operated control inside and outside the cockpit for energizing the release mechanism of a thermal responsive actuating device.

Patent GB-783463-A (GB)
Title: Esters purification process
Inventor: CRAVEN ERNEST CECIL
IPC: C07C69/80
Filed: 1955-05-10
Abstract: Alkyl and oxa-alkyl diesters of dicarboxylic acids are decolourized by treating with ozone and thereafter washing the treated ester with alkali.  Esters which may be treated include the diesters of dicarboxylic acids, such as phthalic acid, pimelic acid, sebacic acid, oxalic acid and tartaric acid, with saturated aliphatic alcohols such as those having four or more carbon atoms, e.g. butanols, octanols, nonanols, and decanols, and the alcohols containing ether linkages such as butoxyethyl phthalate and di-2-ethylhexyl phthalate and the diester of a mixture of C9-C7 oxo alcohols with phthalic acid.  The ozone used may be employed as ozonized air or ozonized oxygen.  The decolourization takes place more rapidly at elevated temperature but temperatures above 100 DEG C. are not so efficient owing to the decomposition of the ozone. After treating with ozone, the ester is washed with aqueous alkali, suitable alkalies being the hydroxides of sodium and potassium.  The concentration of alkali is desirably within the range of 1 to 20 per cent by weight, 10 per cent by weight being preferred.  The washing may be effected at 20-100 DEG  C.  The ratio of ester to aqueous alkali is desirably within the range 20:1 to 5:1 volume/volume, a ratio of 10:1 being preferred.  The ester may then be washed with water at 20-100 DEG  C., the ratio of ester to water being within the range 6:1 to 2:1 volume/volume, a ratio of 4:1 being preferred.  The ester may then be dried by any suitable method, such as chemical drying or heating in vacuo on a water-bath followed by filtration. The treatment with ozone may be combined with further purification processes.  The crude ester may be washed with aqueous alkali before treating with ozone and passed through a tower containing activated carbon after the ozone treatment.  The product may be further treated with ozone to reduce the colour still further. The ester may also be treated with steam after being washed with alkali to remove traces of free alcohols.  Detailed examples describe the treatment of the phthalates of a mixture of C7-C9 oxo alcohols and 2-ethyl hexanol, dioctyl sebacate, and methyl glycol phthalate.  The Provisional Specification refers also to the purification of esters such as di-2-ethyl-hexyl phthalate by treatment with ozone followed by washing with water, without washing with alkali.
