Filed: 1921-10-04
Abstract: 191,137. McBlain, J. Oct. 4, 1921. Oxygen, supplying for combustion; liquid and gaseous fuel furnaces.-In the combustion of solid liquid or gaseous fuels, ozone is used wholly or in part as the oxidizing agent for the fuel, the ozone being incorporated with the fuel during gasification, atomization, and/or preparation to combustion at a comparatively low temperature to avoid reconversion of the ozone into oxygen. In the application to an oil-fired furnace, Fig. 4. the air supply is passed through an ozone generator b and is delivered under pressure by the pump n to the atomizer jets p, where it mixes with the fuel supplied by the pipe q. A supplementary supply of ozonized air may be led to the furnace by the pipe g. In the case of a gas-fired furnace or retort, the ozonized air and gas are mixed prior to delivery to the mixing chambers that feed the burners. In the application to solid fuel, the fuel is preferably delivered to the furnace in a finely divided form. and may be treated with ozone before use, or the ozonized air may be employed to feed the fuel into the furnace. Disclaiming reference is made to Specifications 6573/96, 13840/06, and 26869/06.

Abstract: 1,150,441. Cathode-ray tube mountings. SPECTO AVIONICS Ltd. 23 June, 1966 [23 June, 1965], No. 26567/65. Heading H4T. A mounting for a display cathode-ray tube comprises a structure of insulating material having cylindrical and conical portions (7, 8, Fig. 1), for receiving the tube 1, which may be withdrawn face first when a retaining apertured cap 9 is unscrewed, together with spring- urged contact means 12 which, when the tube is in position supplies E.H.T. via conductor 15 to a terminal contact 11 on the conical portion of the tube. In this embodiment angular location of the tube, to ensure registration of contacts 11, 12, is effected by a peg 16 secured to the neck of the tube and a locating slot 17 formed in the mounting structure. In a second embodiment correct angular location is ensured by means of a resiliently mounted socket (21, Fig. 3), co-operating with the normal pin contacts at the end of the tube neck and the mounting structure is modified by the provision of two spring-loaded plungers 24, 25, Fig. 2, to provide, with contact 12, a resilient three-point bearing for the tube. The mounting structure is further modified by the provision of an insulating sleeve 29 which prevents spring 14 from overextending when the tube is removed and by cut-out portions 26, 27, 28 which reduce the weight of the structure. The assembly further includes a focusing magnet (20) and a mild steel screen (23). The facility of withdrawing the tube face first (e.g. for maintenance or repair) is advantageous when it is installed in positions (e.g. in aircraft) where the neck end is not readily accessible and by making the mounting structure a close fit about the tube the leakage resistance between the E.H.T. contact 12 and the deflection coils 18 is kept at a high value.
