Title: Travelling wave tube
IPC: H01J19/74
Filed: 1966-01-12
Abstract: 1,097,243. Velocity-modulated tubes. COMMUNICATIONS SATELLITE CORPORATION. Jan. 12, 1966 [March 1, 1965], No. 1377/66. Heading H1D. In a discharge tube in which an electron beam is focused along a rectilinear axis by magnetic means to interact with an electromagnetic wave, the collector for the beam is thermally connected to a heat sink surrounding the magnetic means by a plurality of thin, flexible, annular metal discs bonded to the collector and, at their outer peripheries, to a rigid cylindrical member which surround the collector and is itself thermally connected to the heat sink, whereby, by flexure of the discs, the collector may move axially to relieve thermal stress. An electron beam from the gun 14 of a travelling wave tube is received by a collector 19 which is thermally connected to the outer cylindrical cover 35, constituting the heat sink, by the flexible copper discs 36, metal cylinder 37, insulating beryllia cylinder 38 and metal member 39. The slow-wave structure is constituted by a first helix 29 joined to a second helix 30, of smaller pitch, the helices being operated at a voltage which gives optimum gain in the first section, and which consequently exceeds the value for optimum gain in the second, whereby stability with respect to voltage fluctuation is improved. The helices are supported by three axially extending rod members 21; at a region a third of the way along the tube loss material 28 is coated on the surface of the rods but not on the helices, whereby, since the rod surfaces are parallel to the electron beam, deterioration due to bombardment of the coating is avoided. Data on the coating density distribution are given: the region of maximum density is arranged to coincide with the junction of the two helices. The focusing magnet 20 has its central portion cut away in a series of steps 23 to reduce weight, the ferromagnetic discs 26-which are spaced from one another by aluminium spacers 27-improving the focusing. The gun 14 is magnetically shielded by ferromagnetic members 24, magnetic symmetry in the tube being improved by a magnetic member 25 at the collector end of the tube.

Abstract: 157,773. Demand, J. Oct. 20, 1919, [Convention date]. Windows and like, cleaning.-A wind-screen D for a motor vehicle, flying-machine or dirigible, is cleaned by a reciprocating wiper F which is operated by a piston J through cable connections L passing round pulleys M. The piston is reciprocated in the cylinder K by pressure fluid, which is admitted alternately to either end of the cylinder by the piston contacting with interconnected tappet valves g to reverse the movement of the piston. These valves are connected by a rod k and links l, or this rod may be carried directly through the piston as in a modified construction. The pipe b leading into the pipe e communicating with the parts f controlled by the valves g, may be connected with the intake side of the engine, or fluid under pressure may be supplied from the brake reservoirs as in the application of the device to railway vehicles. The wiper is detachably connected to a block O slidable in a cylindrical guide-member G mounted on the wind-screen. The cylinder K is preferably mounted on the lower part of the upper screen member C. When the control valve in the pipe b is opened by the driver, and with the part in the position shown, the piston J is subjected to atmospheric pressure and to suction pressure in the right and left hand sides respectively. At the end of the movement of the piston to the left, the operation of the valves g reverses its action and the wiper F is thus moved to and fro across the screen.

Filed: 1971-01-14
Abstract: 1327142 Automatic control of speed GENERAL ELECTRIC CO 14 Jan 1971 [2 Feb 1970] 1870/71 Heading G3R The speed of a gas turbine 85 is controlled by regulating the output of its fuel pump 83 in response to the difference between an actual speed signal and a reference, the difference being amplified by an operational amplifier 63 which has feedback via a capacitor 65 for a constant speed/load characteristic, or additional feedback via resistors 61, 67 and contacts 69 to produce a desired degree of "droop". The turbine drives a generator which may supply a network in isolation, when constant speed would be required and contacts 69 would be opened, or in parallel with and assisting a main generator, when contacts 69 would be closed to provide the droop characteristic. This enables the generator to take a desired amount of the load, determined by a signal at 73 which is added algebraically to the feedback via 61, 67. During isolated operation the load reference at 73 is made to track the feedback signal via 61, 67 so that change over can occur without shock. A potentiometer 53 enables the fuel supply to be adjusted to achieve synchronous running before the load is applied. The actual speed signal from a tachogenerator is applied via a resistor 75 and the desired speed for isolated operation via a rheostat 77. The fuel pump is driven from the engine so that there is a further speed feedback loop 87.

Title: Process for the production of ammonia from gases containing cyanide of hydrogen
IPC: C01C1/08
Filed: 1925-01-21
Abstract: The water required for the production of ammonia and carbon monoxide by the catalytic decomposition of hydrocyanic acid present in gases which also contain hydrogen is produced in situ at elevated temperature by introducing a gas containing oxygen. If air is employed for this purpose it is advantageous to combine the process with the manufacture of hydrocyanic acid, the gases after absorption of ammonia and addition of hydrocarbons or carbonaceous material and hydrogen being blown through an electric arc.  When the gases containing hydrocyanic acid do not contain sufficient hydrogen for the production of the necessary amount of water, hydrogen must be added before the gases are introduced into the chamber containing the usual catalysts such as ferric oxide, chrome iron or a mixture of ferric and aluminium oxides.
