Title: Improvements in or relating to the treatment of fuel gases
IPC: C10K1/32
Filed: 1944-08-02
Abstract: Fuel gases which have been subjected to a process for the stripping therefrom of benzole, are treated for the removal of residual benzole and of volatile hydrocarbons (other than methane) gaseous at atmospheric temperature and pressure and/or of volatile organic sulphur compounds also gaseous at atmospheric temperature and pressure, by passing the fuel gas into contact with active carbon at a temperature at or below 0 DEG C. (preferably between -30 DEG C. and the liquefaction temperature of methane), and recovering the volatile componds from the active carbon, the fuel gas having been dried prior to contact with the carbon to lower the dew point below the temperature at which contact takes place. The process may be carried out under such conditions that propylene and less volatile hydrocarbons are adsorbed, or so that ethylene and ethane are also removed.  Exhaust steam from the engines driving the gas blowers and the compressors for the refrigeration of the fuel gases may be used to remove the adsorbed compounds from the carbon, and in this case adsorption may be carried out at such a temperature that the amount of exhaust steam required corresponds substantially to the consumption of high pressure steam in these engines.  In a modification of the process different compounds may be removed in a series of low temperature adsorptive steps, and such steps may be operated at successively lower temperatures.

Title: Spatial simulator for maritime tactical navigation with in sight  ships and coastlines
IPC: G09B9/06
Filed: 1973-05-26
Abstract: 1439152 Projection apparatus for simulating navigation R HERVIEU 26 May 1973 14837/73 Heading G2J A device for simulating navigation comprises a cylindrical screen on which images are projected, said images simulating the position of observed objects relative to an observer, the images being mounted on a rotatable carrier, and means being provided for varying the magnification and angle of projection of the images. As shown in Fig. 17, the cylindrical screen 14 forms the walls of the simulation room. A control desk has a helm and a speed control for simulating the manoeuvring of an observed ship NI from a ship N from which bearings are taken, both ships being in motion. These controls supply a computer with coordinates of the position of one ship from the other. A rotatable projector 11 with a variable focal length lens is arranged to project images of transparencies 12 which are reflected by a right angled prism on to the screen 14. The transparencies, of which there are a large number, e.g. 180, are arranged round the periphery of a disc 18, and represent photographs of ship NI, either directly or by means of a model, taken by rotating in steps of e at a time completely round the ship. Thus an image of ship NI may be projected as a representation of what would be seen by the observer by orienting a plate 20, which carries both disc 18 and projector 11, according to the bearing of ship NI from ship N, rotating the disc 18 until the transparency corresponding to the difference in course of the two ships is aligned with the projector, and adjusting the focal length of the projector lens. These three operations are effected by three motors, which are controlled from the computer. Non-moving objects such as islets or a coast line may be superimposed by having additional projectors. Several different ships may be represented by having a separate plate 20 for each ship, each plate being under the control of a separate computer.

IPC: H01P1/12
Filed: 1961-04-27
Abstract: 927,388. Mechanical switches, without quick-action. CONTINENTAL ELECTRONICS MANUFACTURING CO. April 27, 1961, No. 15261/61. Class 38 (5). [Also in Groups XL (b) and XL (c)] A plurality of radio-frequencysources are selectively connected to a plurality of loads by a system of switches. Each of three transmitters supplies one of a set of transmission lines 16, 17, 18, Fig. 1, and each of five aerials is supplied by one of a second set of five transmission lines 11 ... 15 which are disposed transversely to those of the first set, interconnection between. any lines of the two sets being made by interconnecting lines such as 21 and ganged switches such as 31, 32. When not making such connection the switches make to continuations of the transmission lines, as shown for switches 34, 35, and thus isolate the proximate interconnecting line such as 26. As described, the transmission lines 16 .. 18 and 11 .. 15 and the interconnecting lines are screened balanced twin transmission lines but alternatively coaxial lines may be employed. The conductors of the balanced transmission lines 63 and 64, Fig. 5, and interconnecting balanced line 65 are enclosed by metallic ducts 60 of rectangular cross-section and the conductors of each transmission line may be made either to continuations thereof or to the conductors of the interconnecting line by rotation of switch blades 68. The cross-sections of the ducts are such that, considered as waveguides, their cut-off frequency is above the frequency of signals transmitted on the lines so that opening of a pair of switch blades in any transmission line conductors isolates the two parts of the line from each other. When coaxial lines are employed similar considerations apply to the cross-section of the outer conductors of the lines. Suitable contacts to mate with a switch blade 93, Figs. 6 and 7, comprise a bracket 91 integral with a conductor 90, on which bracket is mounted a plurality of conductor fingers 92 which may be provided with contact buttons 94 of sintered silver graphite. A corona shield 95, supported on an insulating support 96, may surround the fingers. The switches may be manually-controlled or remotely by motor or pneumatic means. Switches suitable for pneumatic control may include a movable cylinder 105, Fig. 9, which may be retracted into a transmission line conductor 102 by fluid-pressure admitted by a pipe 116 or extended from the conductor by pressure applied through a pipe 120 to make contact with a socket 106 on conductor 103.
