Title: Method and installation for reducing the concentration of com- bustible gases in tanks
IPC: F17C9/00
Filed: 1972-11-07
Abstract: 1387678 Minimising fire-explosion risk in tanks KONGSBERG VAPENFABRIKK AS 7 Nov 1972 [8 Nov 1971] 51367/72 Heading ASA The concentration of combustible gas in a tank, e.g. a ship's tank, is reduced by evacuating gas through pipes extending from the lower part of the tank to the open air by means of an ejector operated by compressed air, and supplying fresh air to the tank from above. The compressed air may be supplied from a steam turbine-driven or electricallyoperated compressor, particularly the compressor unit of a gas turbine engine of an auxiliary or emergency power set. In a preferred feature the tanks are filled during the evacuating process with water to a level just above the bottom webs in the tanks, as in Fig. 1. Pipes 2 are connected to manifold 3, Fig. 2, of compressed air ejector 4 driven by air from pipe 5 and nozzle 6. Ejector pipe 7 leads air and exhausted gas into larger pipe 8 where further gas is drawn in from 3. Thus 4 is a two-step ejector. Fresh air enters the tanks from the butterworth and access hatch openings in the deck.

Abstract: 1528579 Photo-electric alignment of image carriers MARCONI CO Ltd 28 Oct 1975 [30 Nov 1974] 51937/74 Heading G1A To align a microfilm, microfiche, or ultrafiche image frame 10 in a projection light path the frame carrier is displaced in a given direction until the image 63 of a set of coded marks 18 aligns with predetermined areas of first detector means 65 and the image of the spaces between the marks aligns with predetermined areas of second detector means 66, the coding of the marks being such that the difference in the signals from the first and second detector means when the frame 10 is correctly aligned differs measurably from the difference obtained for all misalignment positions. For alignment in a second perpendicular direction a further set of marks 20 giving image 64 may be provided and the second set may alternatively be disposed along the upper edge of the frame (16) Fig. 2 (not shown). The detectors 65, 66 comprise stripes of CdS on a flat substrate. Alternatively in a further embodiment Fig. 4 (not shown) an element (24) is provided having transmitting and reflecting stripes corresponding to the coded marks and spaces between them respectively,while corresponding gratings (26, 34) serve to improve the signal/ noise ratio at single detectors (30, 32). The use of interleaved prisms and cylindrical lenses is also mentioned. The coded marks may be of different colours and the detectors sensitive to different colours. In the embodiment of Fig. 6 two sets of detectors 68, analogous to sets 65, 66, guard against the effect of possible simulation of the coded marks by the information image 62.
