Title: Improvements in or relating to electron discharge devices
IPC: H01J25/04
Filed: 1940-08-31
Abstract: 543,592. Electron oscillators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 31, 1940, No. 13694. Convention date, Aug. 31, 1939. Addition to 541,477. [Class 39 (i)] ] In ultra-high frequency electron discharge apparatus as claimed in the parent Specification where a stream ofelectrons flows past a gap between two co-axial tubes 50, 51 which are joined by end plates 53, 54 to an outer concentric tube 52 to form a quarter wave concentric live tank circuit the emergence of secondary electrons from the collector cup 62 is prevented by a low potential field. This is obtained by a ring 36, Fig. 2, outside the cup 62, which is at a lower potential than the accelerator 241, the ring's potential being lower still ; or the low potential ring 64, Fig. 5, may be inside the cup which has a return flange 621 facing the accelerator annulus 61. An alternative construction consists in making the collector in the form of a disc separate from a low potential cylinder. In a further form a rod 67 at cathode potential projects through an opening 68 in the collector to deflect the incoming electrons more directly on to the cylindrical side of the cup; a shield 691 is carried by the rod. The construction of the tank circuit is substantially the same as described with reference to Fig. 7 of the prior Specification but the control grid 58 has concave wires 59 to focus the electrons. The accelerator, collector and suppressor electrodes are preferably made of tantalum, carbonized nickel or carbonised nichrome. Parallel wires 69, 70 with a bridge 72 form the input circuit ; the cathode heating current is supplied by the tubular conductor 70 and an insulated wire within it, the conductor 70 acting also as cathode lead. A high frequency byepass condenser 701 is housed within the glass envelope. Air may be circulated round this envelope within the tubes 50, 51, these tubes and the whole tank circuit is separable from the glass envelope. A solenoid 65 outside the tank keeps the electron stream along the centre of the glass envelope.

Title: Apparatus for automatically indicating the incidence of slamming of a ship
Inventor: CLAY JOHN ARMSTRONG
IPC: G01L7/08
Filed: 1969-03-15
Abstract: 1,272,092. Detecting and indicating slamming. MANCHESTER LINERS Ltd. 13 March, 1970 [15 March, 1969], No. 13714/69. Heading B7M. [Also in Division G1] Means for detecting and indicating slamming in ships comprises one or more stack pipes 11 open to the sea through the bottom plating 13, the air space above the water in the stack pipe being connected through pipe 18 to a pressure sensor 14 controlling an indicator 15a and counter 15b. Sensor 14 comprises a diaphragm 26 subjected underneath to the stack pipe pressure, and above to a low air pressure set by valves 30, 31 connected to a high air pressure line. When the bottom plating 13 is exposed during slamming, the stack pipe pressure falls to atmospheric, and the air pressure above diaphragm 26 moves it downwardly to operate a valve 28 to connect air pressure to a pressure switch 29 in circuit with indicator 15a and counter 15b. When water re-enters stack pipe 11, the increase in pressure returns diaphragm 26 to its former position, a baffle 19 preventing entry of water into pipe 18. High pressure air can be admitted to stack pipe 11 via valve 34 to remove blockages. A remote-controlled isolating valve 35 is provided in pipe 18. Valve 36 is used for testing. In another embodiment, Fig. 4 (not shown), the diaphragm is mechanically coupled to the switch, and low air pressure is supplied to the space below the diaphragm and above the stack pipe water level, the pressure due to the water column in the stack pipe normally holding the switch open, and lifting of the bows to expose the stack pipe causing the pressure to fall and the switch to close. Deflection gauges are also mounted along the ship's bottom to detect and measure the deformation of the bottom plating due to slamming, Fig. 1 (not shown). The gauge, Fig. 5 (not shown), comprises a spring- loaded plunger resting on the bottom plating and carrying an iron slug lying within a coil in circuit with a meter 49 on panel 15. A switch is also controlled by the plunger to illuminate a lamp 51 on deflection of the bottom plating to a predetermined extent. Alternatively, the gauge comprises a spring-loaded piston resting on plating 13 and moving in a cylinder hydraulically connected to a manometer which indicates the deformation.

Title: Measuring device applying radiometer action
IPC: G01J1/56
Filed: 1944-07-21
Abstract: 580,784. Radiometers. NEGRETTI, H. N., NEGRETTI, P. E., and GREGORY, H. S. July 21, 1944, No. 14006. [Classes 97 (i) and 97 (iii)] [Also in Group XIX] A measuring device comprises metallic foils, adapted to be relatively deflected by mutual repulsion when subject to radiant heat, and means, from which the desired measure can be derived, for countering the deflection and restoring the foils to their normal relative disposition. As shown, a foil 1 is fixed in a mica frame 2 carried in a low-pressure envelope 4 and has the side facing a window 10 blackened. A second foil 3 is attached at the top only in proximity to the foil 1. When the temperature of the latter is raised by radiant energy, the foil 3 is deflected and may be restored to its original position by gravity invoked by tilting the envelope 4 and its support 5 in the casing 6. The intensity of the radiant energy is indicated by the pointer 7 on the scale 8. In a modification, an electrostatic potential difference is applied to the foils 1, 3 to restore the foil 3 to its original position. In a further modification, the radiant energy is passed to the foil 1 through an iris diaphragm and lens and the foil 3, which in this case is substantially rigid and carried by a pivoted arm, is restored to a predetermined position by using the iris diaphragm to reduce the supply of radiant energy. When used as a photometer, a moving foil is interposed between two fixed blackened foils. A standard source of illumination is placed at a fixed distance on one side of the device, and the source to be measured is adjusted until the moving foil shows, no deflection. When used to measure the moisture content of a gas, the latter is passed through a chamber having opposite windows and the chamber is interposed between the device and a standard source. When subjected to a constant supply of radiant energy, the response of the device depends on the gas pressure in the envelope 4. The device may therefore be used for measuring low gas pressures (see Group XIX). Specification 307,122, [Class 38 (v)], is referred to.
