Patent GB-2064075-A (GB)
Title: Gun
IPC: F41A21/00
Filed: 1979-11-23
Abstract: To improve the performance and efficiency of a gun, air or gas pressure or density in the gun barrel in front of a projectile therein is reduced prior to, or during, firing in order to reduce back pressure on the projectile when it is fired. Air in the barrel ahead of the projectile may be preheated, e.g. by causing a required amount of propellant gases to by-pass the shell as it accelerates along the barrel. Thus the bore wall (10) of the barrel (1) can be locally grooved or fluted as at (11) to allow some of the propellant gases to by-pass the shell (2). Alternatively the bore of the barrel in front of the shell may be pre-purged with a gas of lower density than air, e.g. hydrogen or helium or air may be pumped out of the bore. In the latter case the muzzle of the barrel is sealed, e.g. with a plastic diaphragm which is punctured by the shell on firing the gun. <IMAGE>

Title: Anode disk for a rotary-anode X-ray tube and method of manufacturing same.
IPC: H01J35/10
Filed: 1981-04-01
Abstract: Known rotary-anode X-ray tubes in which a graphite body is soldered to a heavy-metal body forming the rotary anode, have the drawback that the graphite body is damaged by the thermal and mechanical stresses occuring during operation. A heavy-metal body 9 is accordingly provided with a circumferential rim 22 which encircles at least a proportion of the graphite body 10. Between the inner side of the rim 22 and the outer side of the graphite body 10 a layer of solder is provided. It has been found that the graphite body is thus better protected against damage. Moreover, the soldering process is simplified in that the heavy-metal body can be situated below the graphite body during soldering to form a cup containing the solder thus preventing solder contamination of the electron impact surface of the anode. <IMAGE>

Patent GB-829333-A (GB)
Abstract: 829,333. Igniting burners. WOODALLDUCKHAM CONSTRUCTION CO. Ltd. May 6, 1958 [May 6, 1957], No. 14369/57. Class 75(3) An ignition system for a surplus gas burner 1 comprises a valve 5 controlling the supply of gas to the burner 1 and a timing device associated with the valve and adapted to render ignition means operative a predetermined period after the valve has opened. The delay in operating the ignition means allows an explosive gas/ air mixture which may.collect in the piping downstream of the valve to be swept out of the burner. The ignition means comprises a pipe 3 extending to the top of the burner 1 and provided near the bottom with an injector 8 providing a mixture of gas and air through which a flame is propagated to the top of the pipe, the mixture being ignited by a sparking plug 4 located just above the injector. The supply of gas to the ignition tube 3 is controlled by an electrically operated valve 10. In operation when the valve 5 is opened to supply gas to the burner 1 a switch 11 is automatically closed to open the electrically operated valve 10 and to energize a relay 12 which after a delay closes contacts 12a. Operation of a push button switch 13 then energizes an ignition transformer supplying the sparking plug 4. The gas is supplied from a gas holder 2 which is connected to the valve 5 so that the valve automatically opens when the holder is full. A lamp 14 or a hooter is energized when the switch 11 closes. Lamps 15, 16 are controlled by a relay 17 controlled by a thermal switch 18 at the burner head in such manner that energization of lamp 15 indicates that the gas is not burning and energization of lamp 16 indicates that it is burning. In a second embodiment, Fig. 2 (not shown), the valve 29 controlling the gas to the burner is operated by a reversible three phase motor 30 controlled by a four position switch 37. When the valve reaches its one quarter open position it operates a switch 35 which de-energizes the motor and necessitates further operation of the motor control switch 37 in order to open the valve to its full position. The solenoid valve 32 controlling the gas supply to the ignition tube 26 and the ignition sparking plug 27 are energized by a relay 38 which is energized by the valve operated switch 35 just before the valve reaches the quarter open position.
