Title: Process for inhibiting scale formation in subterranean formations
Inventor: YAN TSOUNG-YUAN
IPC: C09K8/92
Filed: 1991-09-03
Abstract: Wells producing oil and gas are treated with formation waters containing selected time-release scale inhibitors to reduce the deposit of scale in the well bore and within the formation. The inhibitors are formed by cross-linking a polyacrylic acid compound of controlled molecular weight from about 1,000 to 10,000 with trivalent chromium cations to produce a water-soluble complex which progressively releases the inhibitor from the formation over an extended period of time. <IMAGE>

Title: Method and apparatus for filling sliver cans of elongate cross-section
Inventor: LEIFELD FERDINAND
IPC: D01H9/18
Filed: 1995-03-31
Abstract: In an apparatus for filling sliver cans (8) of elongate cross-section, e.g. at a drawing frame, the sliver is delivered in coils from a rotating head (7) and the can (8) performs a backward and forward movement in its longitudinal direction during the filling process under the action of a displacement means (9, 10). To produce an apparatus which is simple as regards its layout and construction, and allows production speed to be increased, the displacement means (9, 10) is also adapted to displace the can between the filling position and a position adjacent a store (12) of empty and filled cans to enable changeover of the cans. A loading/unloading device (15) effects changeover. The displacement means comprises a conveyor with or without a carriage (9) and is driven by a motor which is speed-controlled. The motor control device responds to can displacement and filling level sensors. <IMAGE>

Title: Crossed-field amplifiers:anode cooling
Inventor: WORTHINGTON MICHAEL SCOTT
IPC: H01J25/587
Filed: 1995-07-19
Abstract: A double helix coupled vane forward wave crossed-field amplifier utilizes anode backwall cooling and vane channel cooling in its RF slow wave circuit. Backwall channel cooling is provided for the majority of the anodes radial vanes. Additional cooling is provided exclusively for the output vanes (40) via individual coolant passages in each output vane. The passages are machined into each double helix output vane to create a U-shaped channel. A U-tube 42 is inserted and brazed to the machined vane. The vane assembly is then attached to the anode body of which the backwall has holes formed to accept the tubes from each vane. Divided backwall coolant channels 50, 60 are brazed to the outside of the anode, thereby placing in fluid communication the coolant channels to the tubes. The vanes of the anode are thus preferentially cooled. <IMAGE>

The pair of facets (3, 5) of the semiconductor laser (2) and the light responsive surface (10) of the photodiode (9) are both disposed perpendicular to the surface of the semiconductor substrate (1), and the light responsive surface (10) of the photodiode (9) is disposed so that the light of the laser beam reflected by the light responsive surface (10) does not return toward the emitting point (6) of the laser beam. Therefore, due to reflected light noise is not generated in the semiconductor laser (2). In addition, the pair of facets (3, 5) of the semiconductor laser (2) and the light responsive surface (10) of the photodiode (9) can be formed simultaneously by dry etching, thereby shortening the fabricating process. <IMAGE>

Title: Field electron emission materials and devices
Inventor: TUCK RICHARD ALLAN
IPC: H01J29/94
Filed: 1996-08-02
Abstract: A field electron emission material comprises an electrically conductive substrate 13,14 and, disposed thereon, electrically conductive particles 11 e.g. of metal carbide embedded in, formed in, or coated by a layer of inorganic electrically insulating material 12 (e.g. glass or diamond). A first thickness 15 of the insulating material is defined between each particle 11 and the substrate 13,14 and a second thickness 15 of the insulating material is defined between the particle 11 and the environment in which the material is disposed. The dimension of each particle 11 between the first and second thicknesses 15 is significantly greater than each thickness 15. Upon application of a sufficient electric field, each thickness 15 provides a conducting channel, to afford electron emission from the particles 11. By use of an inorganic insulating material 12, surprisingly good stability and performance have been obtained. The particles 11 can be relatively small, such that the electron emitting material 11, 12 can be applied to the substrate 13,14 quite cheaply by a variety of methods, including printing. The material can be used in a variety of devices, including display and illuminating devices. When used in a display device, gettering material can be located at sites which would normally be occupied by spacers between the anode and cathode. Alternatively the gettering material may be co-located with the field electron emissive material.
Patent GB-2304408-A (GB)
Title: A viscometer
Inventor: TAYLOR JAMES C
IPC: G01P3/36
Filed: 1996-08-09
Abstract: An apparatus for use in measuring the kinematic viscosity of a fluid comprises a vertical tube 2 in which a sample 1 of the fluid is permitted to fall under the influence of gravity at a velocity determined by the viscosity of the fluid. Light from a source 3 illuminates the fluid axially via a beam splitter 4 and is partially reflected back towards the source from a surface of the sample. The reflected light is recombined in the splitter with a reference beam in order to generate fringes which are detected by an optical detector 6. The rate at which fringes pass the detector 6 is a measure of the falling velocity of the fluid. This velocity may thus be deduced and used to determine the kinematic viscosity of the fluid.
