Title: Lasers
IPC: H01S3/0953
Filed: 1976-01-27
Abstract: 1519031 Lasers ROLLS ROYCE Ltd 27 Jan 1976 [28 Jan 1975] 3585/75 Addition to 1390919 Heading H1C In a CO 2  gas dynamic laser, either combustion gas or compressed air is tapped off an air breathing gas turbine engine, and a laserable gas mixture is produced by burning one or more hydrocarbon fuels in the tapped off gas, the laserable gas being aerodynamically expanded in a supersonic nozzle to produce lasing in an optical resonator. It is a requirement that the total amount of fuel added to the tapped off gas is such as to produce a gas fuelair mixture, before burning, having a ratio of between 0À35 and 0À85 to its stoichiometric mixture. A gas turbine 1 is shown in Fig. 1 having a compressor section 2, combustion equipment 3, a turbine section 4 and a jet pipe 5, a portion of the combustion gas being taken off at the outlet end of the combustor 6 and passed to a reservoir/combustion chamber 8 where fuel injected at 9 is burned. The laserable gas mixture so produced is passed through convergent-divergent nozzles 10 developing supersonic flow, and lasing takes place in an expansion chamber 11 bounded by an optical resonator C to produce an output beam 12. The exhausted gases are removed from chamber 11 by a compressor 13 so as to pass through a duct 14 into the jet pipe 5. Alternatively a diffuser unit may be used. A parallel line of converging-diverging nozzles may be used, Fig. 3 (not shown), or alternatively a system of flow turning axi-symmetric nozzles 18, 19, may be used, Fig. 5, for both supersonic expansion and diffusion. An embodiment using tapped-off compressed air is described, Fig. 2 (not shown), this embodiment differing from Fig. 1 only by the inclusion of a further supply duct used to supply additional substances as needed to the reservoir 8, and by the engine tapping point at the compressor section. The hydrocarbon fuel or fuels used is/are selected to give a gaseous H 2 O : CO 2  ratio in the combustion gases in the range between 1 : 2 and 2 : 1, a suitable fuel mixture being of two different hydrocarbon fuels of carbon to hydrogen content of 1 : 2 or more and less than 1 : 2, respectively. The main hydrocarbon fuel may be aviation kerosene or benzene, but examples of other fuels are given. The additional fuel, if used, may be carbon monoxide, carbon disulphide, cyanogen or finely divided carbon. Other gases may also be added to the combustion gases before expansion such as air, nitrogen or carbon dioxide. The additional fuel may supply a pilot burner for a main burner through which the main fuel is passed.

The board is marked around its periphery with forty spaces over which the pieces of the players are moved according to the throw of dice or by other chance determining means, commencing at the lower right-hand corner. Three such pieces are shown in Fig. 2. Twenty-two of the spaces on the board are marked with the names of streets, avenues, or places to indicate real estate areas and are also marked with bands c of colour, different groups of such areas bearing distinctive colours. Other spaces are marked to indicate Community Chest, Chance, Railroads, Utilities, Income Tax and Luxury Tax. A set of title cards one of which is shown in Fig. 6, correspond to the real estate areas and are marked with various rentals and values. If a player's piece lands upon an unoccupied estate area, he may acquire the corresponding title card on payment of paper script previously distributed to the players one of whom acts as Banker. The player may then proceed to develop the estate area according to the rules of the game by placing one or more model houses or an hotel, Fig. 3, upon the area. Other title cards similarly deal with monetary values in connection with Railways and Utilities, such as electricity or water. Other cards marked Chance and Community Chest must be drawn by player whose piece lands on corresponding areas of the board, and these cards involve financial or other penalties or benefits to the players.

Abstract: 579,315. Electron-oscillators. MANIFOLD, M. BOWMAN-. March 29, 1941, No. 4253. [Class 39 (i)] In electron discharge devices of the type in which an electron stream is velocitymodulated by passing across a gap in a hollow resonator and is then reflected back through the gap, means are provided to make the reflecting equipotential surfaces concave towards the gap and substantially concentric to avoid loss by spreading of the electron stream. With a resonator 1 of toroidal shape having a flat rear surface, the reflecting electrode 3 is of hemispherical shape with an inturned flange 4 lying adjacent the rear surface of the resonator. A further electrode 5, of disc shape with an aperture in line with the resonator gap 2, lies in the plane of the flange 4, and is given a potential intermediate that of the electrode 3 and the resonator. The shape of the reflecting electrode 3 and the electrode 5 is adapted to other forms of resonator such as that described in Specifications 523,712 and 577,037, and to a flat electron beam as described in Specification 574,512. The disc electrode may be formed of a material having a resistance such that the potential progressively increases from the rim, or it may be made up of a number of separate rings with potentials increasing towards the gap. It is not necessarily flat, but may consist of one or more conical frusta.
