Abstract: 798,462. Liquid-pressure engines. HOOYDONK, A. H. VAN. July 28, 1954 [April 29, 1953; June 4, 1953], Nos. 11890/53 and 15463/53. Class 69 (2). [Also in Group XXVIII] In a liquid-pressure engine, a number of cylinders 29 are arranged about a shaft 18 and contain pistons 25 driving a swash-plate 21. Each cylinder communicates with a port 30 in a valve plate 13 and these ports are opened to inlet and exhaust by an annular valve mounted in an eccentric 19 and located between the valve plate 13 and a cover 15. The valve has lands 35, 37 separated by a slot 43 so that fluid pressure forces the lands apart and maintains a seal between the land 37 and the valveplate 13. In a modification, two engines are coaxially opposed and the land 35 controls the ports of the second engine. In another valve construction as shown in Fig. 4, the lands 37, 57 have two slots 54, 55 between them and the force caused by the fluid pressure to separate them is reduced by providing a rubber sealing band 58 which is backed by a split steel band 59 to prevent the band 58 being forced into the slots 54, 55. Specification 516,721 is referred to.

In use,' the sensitive sheet 36 is led over roller 60 and across the focal surface for exposure, after which it meets the receiving sheet 40 and is drawn superimposed therewith between pressure roller 86 and pressure plate 88 to rupture a container and effect processing while the two sheets lie in a dark chamber between inner closure means 70 and outer closure means 72, which means are pivoted at the left and right sides,.. respectively, of the camera, and are shown in open position for access to the interior of the camera in Fig. 2, and in closed position to form the dark chamber in Fig. 3. After a predetermined processing time the outer closure means 72 is opened for removal of the processed sheets, at which time the inner closure means maintains darkness in the interior of the camera. A modification, Figs. 6-11, not shown, for use with sensitive and receiving sheets with opaque backings, has a single closure means instead of the pair 70, 72 and processing is allowed to proceed after the two superimposed sheets are withdrawn from the camera.

Abstract: 1,147,056. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. 22 March, 1965 [25 March, 1965], No. 12505/66. Heading H1K. A helicon wave amplifier comprises two onecomponent plasma supporting media with a common interface, means for providing a magnetic field in the media parallel to the interface and for producing a current parallel to the interface in at least one of the media such as to cause interaction between the resultant surface wave at the interface and the bulk helicon wave to provide a net gain, and signal input and output arrangements. In a typical embodiment a first plasma supporting medium is sandwiched between a pair of second plasma supporting media, all three media being of doped lead telluride, though other semi-conductors, semi-metals and metals are suitable. The media may be supported in a rectangular waveguide with the interfaces parallel to a wall and the magnetic field and current running along the length of the guide, the current being confined to the first plasma. Matching may be provided by wedges of dielectric attached to the leading and trailing ends of the sandwich or by tapering off the carrier concentration at the ends of the sandwich. Improved coupling may instead be provided by a linear to circular polarization mode converter. In another arrangement the media, mutually insulated along their lengths, are interconnected at the ends so that the directions of current flow in the central and outer media are opposed. In both arrangements the current level is adjusted so that the Doppler shifted dielectric constant in the medium of lower dielectric constant exceeds that in the other. An arrangement of media in annular layers inserted between the inner and outer conductors of a coaxial line is operated in the same way. Yet another embodiment consists of a pair of superposed planar media with chamfered ends between which the biasing current is pasesd with input and output coils dispersed at the ends adjacent the bias current electrodes.

Patent GB-635717-A (GB)
Title: Improvements relating to breaking water in oil emulsions
IPC: C10G33/06
Filed: 1947-05-09
Abstract: A method of breaking water-in-oil emulsions comprises determining the water content of the emulsion and adding an amount of water-soluble surface-active agent to give a concentration of the agent in the water content of the emulsion which is about the critical concentration beyond which the surface tension of the solution is not appreciably reduced by increasing the concentration.  Thus an emulsion of seawater in marine fuel oil can be broken by the addition of an amount of a sodium secondary alkyl sulphate to give a 0.1 per cent concentration in the water content and preferably heating to 100-150 DEG  F.  If heating is not resorted to, an unpumpable sludge can be rendered pumpable by agitation with the surface-active agent by air-blowing.  The critical concentration may be reduced by the addition of polyvalent ions such as those of calcium or aluminium added, for example, as chloride.
