Title: Improvements in or relating to cameras for use on aircraft
IPC: G03B17/56
Filed: 1932-08-10
Abstract: 402,890. Photographic cameras; gyroscopic apparatus. BOWEN, I., Air Ministry, Kingsway, London. Aug. 10, 1932, No. 22389. [Classes 97 (iii) and 98 (i).] A camera and a gyroscopic vertical indicator are combined so that the images of an index mark on the gyroscopic system and a datum mark fixed relatively to the camera which show the relative tilt of the indicator and the camera, are recorded simultaneously with the image of the ground when the camera is operated. As shown, the gyroscope rotor 1 is mounted in gimbals 3, 5 in a casing 7 relatively to which it is constrained by an electro-magnet 8 which produces eddy currents in a metal disc 9 on the rotor spindle and tends thereby to maintain the rotor spindle erect to the casing. Alternatively the rotor may be constrained relatively to the casing by means of a spring. The casing 7 is secured to the body 10 of the camera, of which 11 is the film box and 12 the lens cone, by means of an intermediate casing 7x containing an optical projection system comprising a prism or mirror 13, a lens 14 and a prism or mirror 15 disposed in a tube 16 secured in the casing 7x. Alternatively the casing 7 may be secured to the film magazine or the lens cone of the camera. A disc 20 bearing an index mark is mounted on the gimbal ring 3 in alignment with the rotor axis 2, and the optical system 13, 14, 15 projects an image of the index mark on to the film. An image of the graticule 21 is also projected on to the film. An electric lamp bulb 22 illuminates the disc 20. The camera main blind 23 and the capping blind 24 or their release mechanism are arranged to close the lamp circuit to illuminate the disc 20 at the time of exposure. Alternatively, the optical system 13, 14, 15 may be arranged so that the index mark on the gyroscopic vertical indicator and the graticule fixed relatively to the camera are photographed on a separate film or plate from that on which the ground is photographed. Instead of controlling the photographing of the index mark and the graticule by means of the camera blind or shutter it may be controlled by a blind or shutter working simultaneously with but separate from the camera blind or shutter, or by the lamp 22. A large graticule concentric with the optical axis 25 of the camera may be provided on the glass plate 26 against which the film is pressed. In a modification a gyroscope rotor pendulously controlled may be used as a pitch and roll indicator.

Title: Method of adiabatically oxidizing a carbonaceous fuel
IPC: F23C13/00
Filed: 1972-05-12
Abstract: 1395422 Generating combustion products under pressure; gas turbine plant ENGELHARD MINERALS & CHEMICALS CORP 12 May 1972 [13 May 1971] 22494/72 Headings FIG and F1L To reduce the content of hydrocarbons, carbon monoxide and nitrogen oxides in the reaction products, a method of adiabatically oxidizing a carbonaceous fuel which when burned with a stoichiometric amount of air has an adiabatic flame temperature of at least 3300F comprises passing a mixture of the fuel in vaporous form and air through a zone containing an oxidation catalyst at a temperature of between about 1700 and 3000F and at a velocity, at or prior to the inlet of the zone, in excess of the maximum flame propagating velocity of the mixture under the conditions. The volume ratio of free oxygen to fuel in the mixture is at least 1.5 times the stoichiometric amount and the mixture is in or on the fuel-lean side of the inflammable range and has a theoretical adiabatic flame temperature of between about 1700 and 3000F at the conditions of the initiation of oxidation. The fuel may be gaseous or liquid at ambient conditions, e.g. methane, ethane, propane, naphtha, carbon monoxide and alkanols of I to 4 carbon atoms such as methanol. The catalyst may be in the form of  small solid particles packed into a bed or may be a skeletal structure consisting of a catalytically active metal carried by a less active or inert support 'such as a ceramic. The catalytic metal may be from groups IB, IIB, or III to VIII of the periodic table, e.g. silica, alumina, zirconia, platinum, palladium, rhodium, copper, chromium, nickel, cobalt, vanadium, iron or combinations thereof. In one application a gas turbine plant comprises a compressor 12, catalytic reaction chamber 30 and a turbine 14. At starting, ignitor 36 is activated and fuel, e.g. naphtha, is tapped from line 15 via branch 39 and valve 27 to enter reaction chambers 30 where it burns with a flame to raise catalyst 31 to oxidation temperature as sensed by thermocouples 32, 33. Ignitor 36 is then deactivated, valve 27 shut and valve 16 opened so that fuel is now sprayed into the air inlet 23 of compressor 12. The compressed mixture enters reaction chamber 30 at a velocity greater than the maximum velocity for flame propagation, e.g. at least 3 ft/sec, where the fuel is flamelessly oxidized by catalyst 31, the residence time in the oxidation zone being less than 0.1 sec. The hot products expand through turbine 14, which may drive a vehicle or electric generator, or alternatively are used to heat a steam generator. The air and fuel may be pre-heated prior to entering chamber 30. The volume of air to fuel may be above 20:1 and as high as 200:1. Cooling air may be added to the reaction products. Another plant operating in similar manner but using propane fuel comprises, Fig. 2 (not shown), a centrifugal compressor (112), mixing vanes (122), pre-heater (125), catalyst chamber (131) and axial-flow turbine (138).

Patent GB-591796-A (GB)
Title: Improvement in catalytic dealkylation of alkyl aromatic compounds
IPC: C07C1/20
Filed: 1944-11-15
Abstract: An alkyl aromatic compound having at least one alkyl substituent containing three or more carbon atoms is dealkylated by contacting with an active clay or clay-like catalyst, including both activated clays, and natural clays which are surface active, at about 200-600 DEG  C.  The said alkyl substituent is split off without removing any methyl or ethyl groups present.  Suitable catalysts are Georgia clay, floridin, attapulgus clay, diatomaceous earth, and fuller's earth, generally in the form of 30-60 mesh granules.  Alkyl phenols can be dealkylated at about 250-300 DEG  C. while with hydrocarbons such as alkyl benzenes or naphthalenes, 500-550 DEG  C. is desirable.  A fixed or moving bed or suspended catalyst may be used.  With a fixed bed and vapour phase operation, space velocities of 0.2-3 are suitable.  The compound to be dealkylated may be vaporized, heated to 200-600 DEG  C., and passed downwards through the catalyst, products being fractionated to obtain olefins, aromatics, and unconverted charge, which is recycled.  A second catalyst container may be provided for continuous operation while the spent catalyst is being regenerated with air and flue gas.  The separation of, for example, m- and p-cresol by alkylating a mixture thereof with isobutene, separating the di-tert.-butyl derivatives by fractionating, and then debutylating is referred to.  In examples, di-tert.-butyl meta-cresol is treated with Georgia clay at 260 DEG  C. and various space velocities, and at temperatures ranging from 260-500 DEG  C. at a space velocity of 0.23, giving substantially theoretical yields of cresol and isobutene mixed, at the higher temperatures, with isobutane.  Di-tert.-butyl para-cresol is similarly dealkylated. Amyl-, tert. - butyl-, and di - ethyl - benzenes, and cumene at temperatures of 350-500 DEG  C. similarly yield benzene and olefins, in some cases mixed with paraffins.
