Title: Linear accelerator for electrically charged particles and generator of electromagnetic pulses
IPC: H05H9/00
Filed: 1950-11-09
Abstract: 711,785. High-frequency discharge apparatus; particle accelerators. RAUDORF, W. R. Oct. 30, 1951 [Nov. 9, 1950], No. 27358/50. Class 39(1) A charged particle linear accelerator comprises an axially symmetrical tube T having three sections 1, 2, 3 and an axially symmetrical magnetic field which vanishes in the region of the cathode section 1, is uniform in section 2 and increases rapidly in the region between sections 2 and 3.. The cathode section 1 is magnetically screened. Current pulses are abstracted from the cathode K by means of a grid G. Two grids may be used, one for withdrawing the charged particles and the other for accelerating them. The duration of a pulse is long compared with charged particle transit time in the tube. The operation is. stated to be as follows: the beam of charged particles rotating but cylindrical in form in section 2, is radially compressed in the region of increasing magnetic field intensity between sections 2 and 3, and a space-charge limited virtual cathode is formed. As the virtual cathode develops, the beam current falls off, and the magnetic field due to the beam collapses. The collapse of this magnetic field induces an electric field in section 3. The charged particles beyond the virtual cathode i.e. those forming the front of the beam, are then accelerated by the induced electric field. The energy of the magnetic field associated with the beam of charged particles is transferred to the charged particles which constitute the front of the beam. The effect is stated to be analogous to that of an hydraulic ram. The accelerator may be used to generate a pulse of electromagnetic waves, section 3 being shaped to provide a parabolic reflecting surface and closed by a glass plate, or to generate X-rays. The beam of charged particles may be concentrated by a combination of magnetic and gas-focusing methods. Two or more accelerator tubes may be used in series.

Title: Improvements in and relating to liquid level governors
IPC: G05D9/02
Filed: 1959-08-11
Abstract: 922,956. Valves. B. CAVLING, and S. O. RYE. Aug. 11, 1959, No. 27449/59. Class 135. A liquid-level governor suitable for controlling the level of fuel oil supplied to a burner comprises a valve member 4 coacting with a seat 3 at the inlet to a container 1 and connected to a lever 5 which is pivoted at 6 and carries a float 8 and a counterweight 9, the float having a lost-motion connection with a forked end 10 of the lever and carrying an armature 13 which coacts with a permanent magnet 14 fixed to a cover 2 of the container. As shown, the liquid level is such that the valve is closed under the effect of the counterweight 9 and the lost-motion between the float and the lever is such that any slight reduction of level will cause the valve to open at a rate greater than that at which the level falls due to the reduction of magnetic attraction between the magnet 14 and armature 13 as the latter descends. Should the valve member fail to seat properly the continued rise of level in the container 1 will cause the armature to be brought into contact with the magnet 14 at the same time causing a blow to be delivered to the valve member to assist in seating it. A pushbutton 18 with an inclined portion 19 coacting with a projection 20 is provided for separating the armature 13 from the magnet to resume normal functioning. An additional safety device operative after the armature has engaged the magnet consists of an upwardly open float 15 on the valve spindle in which float is filled to hold the valve closed in the event of excessive rise of liquid level.

Sept. 27, 1955 [Oct. 7, 1954], No. 27481/55. Addition to 788,161. Class 75(1) The arrangement for feeding liquid fuel to a burner of the parent Specification in which fuel is fed to the burner from a supply tank through a heated riser pipe having its top opening at a higher'level than the fuel in the tank has the heated part of the riser at a point below the lowest possible level in the fuel supply tank and the regulator which regulates the fuel supply to the burner is isolated from the burner head. A fuel tank 11 consisting of upper and lower parts 12 and 13 has the upper part 12 filled through a tube 14 on removal of a cover 39. After filling, the cover 39 which allows air to enter the tube 14 at atmospheric pressure, is replaced to depress a rod 40, slidably held in a guide 48, to move a spring loaded ball 41 away from a seating 42 thus allowing the lower part 13 to be filled with fuel to the level S defined by the bottom edge of the tube 14. A tube 46 extends from below the fuel level S into a dome 47 with its upper edge above the upper edge of the mouth of the tube 14. The chamber 13 is open to atmosphere through a tube 15. The fuel from the part 13 enters chambers 19, 20 and 27 of a regulating unit 18 and tubes 28, 29 and 34 and is normally maintained therein at the level S. Fuel also enters and reaches the level S in a chamber 16 from a pipe 17 through a three-way cock 38 when the cock is in the position shown. The chamber 16 is contained in the part 13 and is open to atmosphere The fuel supply to the burner 30 is regulated-by the adjustment of a screw 26 bearing against the stem of a spring-loaded member 24 provided with a conical head which opens, closes or varies the cross-section between the head and an aperture 23 in a member 22 located in the chamber 20. On starting, the cock 38 is turned anti-clockwise to allow the fuel in the chamber 16 to pass through the pipes 35, 37 and 33 to the burner 30 where it is burnt and so heats the riser 29. The riser 29 on being heated causes the fuel contained therein to pass over the top part of a pipe 31 vented at 31<SP>1</SP>, down a pipe 32 to the burner 30 through a pipe 33. Should the fuel supply to the riser 29 from the part 13 cease the heated oil circulates around the closed circuit comprising, the pipe 34 and the riser 29 and burner is consequently extinguished.

Abstract: 403,201. Heating carburetters, vaporizers, and other engine parts. DODSON, E., 66, Lewin Road, Streatham, London. Oct. 4, 1932, No. 27526. [Class 7 (iii).] Carburetters, vaporizers, induction pipes, &c. are heated by a fluid flowing in a continuous circuit wholly independent of any main engine-cooling system and connected with a relief tank to which some of the fluid can be driven, to be out of contact with the heating means, by the vapour pressure of the fluid as the fluid temperature rises, the arrangement avoiding excessive temperatures. A heating jacket 11 for a carburetter 12 is disposed in a closed circuit 13, 14 including a portion 15 heated by either exhaust gases, engine-cooling liquid or conduction from the cylinder walls, the heating fluid circulating either on a thermo-siphon system as shown or by a pump 20. A branch pipe 17 leads, through a restricted opening 21, to a closed reserve tank 18 and when the heat transmitted to the system is excessive, it vaporizes the fluid driving the liquid portion thereof towards the relief tank and the vapour carries a smaller amount of heat to the carburetter. As applied to an air-cooled radial aeroengine, the heating portion 15 extends throughout the exhaust ring. A branch of the system may extend around and heat a car body or aeroplane fuselage. Specification 197,827, [Class 7 (iii), Internal-combustion engines, Carburetting apparatus &c. for], is referred to.
