Title: Method and apparatus for separating water and oil
IPC: E02B15/04
Filed: 1968-10-01
Abstract: 1,210,967. Separating oil from water. STANDARD OIL CO. 1 Oct., 1968 [2 Oct., 1967], No. 46463/68. Heading C1C. Oil is removed from water by contacting the contaminated water with a porous, resilient filter material which selectively absorbs oil, and regenerating the filter material by removing the absorbed oil to render the material reusable. In one embodiment (see Figs. 1 and 2) the apparatus for removing oil is mounted on a tank 21 and comprises a power driven roller 33, and a rotating perforated cylinder 26 round which passes an absorption filter 36, which is preferably formed of expanded polyurethane. The means for regenerating the filter 36 comprise a roller 34 serving to lightly press the filter 36 to remove water therefrom and a roller 35 which exerts a substantial pressure against the filter 36 to remove oil therefrom, the oil being removed from the apparatus via a trough 37. The difference in the water levels outside and inside the cylinder 26, i.e. 45 and 47 respectively, provides a differential head of water which produces a flow of water into the cylinder. The substantially pure water is removed from the interior of the cylinder 26 through its open end 38. In alternative embodiments, (Figs. 4 and 5, not shown), the regenerating means comprises (a) a distributor jet (43) which strays water through the filter to remove particulate material, followed, in the direction of rotation of the filter, by roller 35 and trough 37; and (b) a thin plater or blade (37a) pressed against the surface of the filter to function as a wringer and inclined at such an angle that it acts as a trough to remove the oil from the system, respectively. In a further embodiment (Fig. 6, not shown) the absorption filter forms a sheath on a single closed cylinder and is regenerated by a roller (35) assisted with a trough.

Filed: 1972-10-13
Abstract: 1385258 Two-part couplings GENERAL ELECTRIC CO 13 Oct 1972 [21 Oct 1971] 47385/72 Heading H2E [Also in Division H1] A section of transmission line for insertion between a source of signals and a load consists of a generally cylindrical outer conductor, an inner conductor disposed within it and a voltage surge suppression element consisting of a member of metal oxide based varistor material having an α > 10 in the current density range 10<SP>-3</SP> to 10<SP>2</SP> amps/cm<SP>2</SP>. and having outer and inner peripheral portions respectively contacting the outer and inner conductors. In the typical arrangement shown in Fig. 2 the toroidal varistor member 40, made of one of the zinc oxide based materials described in Canadian Specification 831,691 has metallized surfaces 31, 32 prepared, e.g. by application of silver-glass frit by silk screening and firing at 550 C. To reduce shunt capacitance and hence improve the impedance-frequency response the metallized surfaces may alternatively consist of concentric annuli on one face of the toroidal member abutting shoulders on the inner and outer conductors respectively and if smaller surge currents are anticipated a thinner member epoxy bonded to an alumina support may be used. The tendency for surge current to concentrate in one part of the member due to inaccurate placement of the metallization can be reduced by providing the inner annulus with flat ended radial projections and providing parallel flats on the inner edge of the outer annulus. Two (or more) inner conductors each surrounded by a toroid of varistor material may be provided as shown in Fig. 11.

Abstract: 1,195,269. Semi-conductor device. WESTINGHOUSE ELECTRIC CORP. 18 Oct., 1967 [24 Oct., 1966], No. 47429/67. Heading H1K. An area is exposed on the surface of a substrate by forming on a major surface of the substrate a first layer of insulating material of a first thickness over its entire area except for a first strip having a second thickness less than the first, superimposing on the first layer a layer of electron bombardment - responsive material and exposing it to an electron beam to form an etchresist mask having at least one strip or gap intersecting the first strip and exposing the area formed by the intersected portion by removing material therefrom. The material is removed to a thickness at least as great as said second thickness but less than said first thickness. An N-type Si wafer 20 has formed thereon an oxide layer 22 and 22A, the portion 22A being thinner than 22 and in the form of a stripe running across the wafer (Figs. 3 to 5 not shown). A resist mask 24 in the form of stripes preferably at right angles to the stripes 22A is provided and the parts of the oxide layers 22, 22A left exposed are etched to expose the wafer below portions 22A giving a reduced oxide thickness on the exposed parts of 22 (22B, Fig. 10, not shown). Boron is deposited on the surface and then diffused into the wafer and the wafer annealed to redistribute dopants. A thin oxide layer (22C, Fig. 10, not shown) is formed over the wafer and another resist mask (26, Fig. 12, not shown) having a stripe opening is provided on the oxide covering parallel to the portion 22A. The uncovered portions of the oxide 22D, Fig. 13, are etched to expose the wafer under the thin oxide layer and phosphorus difused in to give a planar transistor. Electrode connections of deposited Al are formed using another resist mask. The oxide layers are built up by the successive deposition of layers. Nitrides may be used in place of the oxide layer. The resists are of the positive type for the oxide layers but of the negative type for the electrode connections. The silicon wafer 20 may be a uniform substrate or an epitaxial layer on a substrate of different conductivity or resistivity. An electron beam microscope may be used to align the resist masks. In one technique, a reverse bias is applied across the PN junction and the voltage contrast effect on the secondary electron image is used. In another the photovoltage developed on a uniform beam as it scans the junction is measured.
