Abstract: 1,256,398. Lasers. ELLIOTT BROS (LONDON) Ltd. 24 Sept., 1970 [26 Sept., 1969], No. 47442/69. Heading H1C. In a gas, e.g. CO 2 , laser, dissociation of the gas during operation is overcome by circulating the gas over a reassociating catalyst. A circulating system for a gas laser 10 is shown in Fig. 2, and comprises laser inlet and outlet gas ports 52, 54 respectively connected to flow control valves 70, 56, a heating device 58 for raising the gas temperature to enhance reassociation in a catalyst chamber 60, and a cooling device 62 for reducing the gas temperature to that required for laser operation. The gas is circulated by a pump 64 which is followed by a further cooling device 66 to remove gas temperature rise occurring within the pump. Gas control taps 68, 84, 88 are provided in the system to enable the laser tube 18, Fig. 1, to be initially evacuated by a pump 86, and the required proportions of CO 2 , He and N 2  to be introduced in the system from pressurized gas storage devices 72, 74, 76, through flow control valves 78, 80, 82. Option - ally the system may use either the same gas mixture continuously or the gases may be replaced from the storage devices during operation. The catalyst chamber 60, Fig. 3 (not shown), comprises a honeycomb matrix of alumina coated with finely divided platinum as the catalyst over which the gas flows. The laser tube 18, Fig. 1, extends between electrodes 20, 22, 24 energized either from a D.C. source 42 or by A.C. Alternatively the laser gas may be optically pumped by a flash tube. Adjustable mirrors 14, 16 are coupled to the ends of the tube by bellows 30, 32, semitransparent mirror 16 being formed of germanium. A folded laser construction is also described, Fig. 4 (not shown).

Abstract: 1,076,679. Triggering arrangements for surge arresters. GENERAL ELECTRIC CO. Nov. 12, 1965 [Dec. 11, 1964], No. 48038/65. Heading H2H. In a surge arrester and circuit arrangement generally similar to that of Specification 1,076,377, the arrester 16 is provided with a second trigger electrode 132 responsive to switching surges of relatively low frequency transmitted thereto by a step-up transformer 100, whose windings are arranged so that a voltage surge of one polarity produces a voltage of opposite polarity on the electrode 132. Thus, when spark-over to electrode 24 occurs, the instantaneous voltage between electrodes 22, 24 is the arithmetic sum of the surge and trigger electrode voltages, Fig. 4(a) (not shown), thereby assisting breakdown of the main gap 25. Capacitor 36 is chosen so that the other trigger electrode 32 responds to lightning surges, the operation for the clearance of such surges, of powerfollow current and of switching surges being similar to that described in the abovementioned Specification. In another embodiment, Fig. 1 (not shown), the invention is applied to a surge arrester and circuit arrangement generally similar to that of Specification 1,026,021.

Title: Improvements in forced recirculation steam generators
IPC: F22B37/70
Filed: 1962-12-20
Abstract: 949,028. Forced flow steam boilers; heating feedwater. H. VORKAUF, and LA MONT INTERNATIONAL ASSOCIATION Ltd. Dec. 20, 1962 [Aug. 8, 1962], No. 48085/62. Addition to 949,025. Heading F4A. The forced recirculation boiler described in the parent Specification is modified in that all or part of the feedwater is brought into indirect heat exchange contact with the circulating water before entering the mixing vessel, the thus cooled circulating water being withdrawn from the heat exchanger by the circulating pumps and delivered into the mixing vessel. The risk of steam formation in the circulating pump suction lines in the event of a fall in boiler pressure is thus reduced. The heat exchanger may consist of a tube coil conveying the feed water disposed in the boiler drum, Fig. 1 (not shown). Alternatively, a coil 10 may be located in a header 11, Figs. 2, 3, receiving circulating water from the drum 1 through pipes 12. The cooled circulating water flows to the pumps 3 through downcomers 2 and is delivered through pipes 4 to the mixing vessel 5 wherein it mixes with the preheated feed water entering through a pipe 8. The steam generating tubes 7 are supplied with the mixed water from the vessel 5 via a header 6. Any steam liberated in the header 11 is led to the steam space of the drum through a pipe 14. In a modification the heat exchanger header is disposed vertically.

Abstract: 1,080,548. Electric selective signalling. EASTMAN KODAK CO. Dec. 7, 1964 [Dec. 6, 1963], No. 49710/64. Heading G4H. A continuously-variable signal (e.g. sound) is sampled at a constant rate, each instantaneous sampled amplitude being optically encoded as a row of digits (e.g. on film), and the rows of digits are moved, at a rate equal to the original sampling rate, past means which optically sense the rows and produce an analogue signal from each. The digits in a row may be sensed separately and the digitalto-analogue conversion done in a strobed weighted-resistor network which produces a voltage which is amplified and fed to a loudspeaker. Alternatively, a single photo-detector may be provided to produce the analogue signal directly, the intensities of the light fluxes from the separate digits of the row being adjusted in accordance with their weights, by an " optical wedge " mask or by light fibres through which the light passes, before reaching the detector.

Vinyl acetate is prepared by reacting ethylene with acetic acid and oxygen in the gaseous phase at an elevated temperature in the presence of a catalyst containing palladium metal and one or more alkali metal salts, e.g. acetates or compounds which can form alkali metal acetates under the reaction conditions. The process is continuous and a small quantity of one or more alkali metal salts is added continuously or intermittently to one or more of the reactants so that the composition of the palladium carrier catalyst (i.e. noble metal, alkali metal acetate and carrier) is kept constant and optimal. The addition of the alkali metal compound preferably in the form of a solution, to the reactant or reactants may be accomplished by passing the latter partly or entirely in the gaseous form through a solution of alkali metal compound or through layers of solid bodies impregnated with alkali metal compounds.
