Patent GB-2197849-A (GB)
Title: Manufacture of bags
Inventor: STEER GRAHAM EMERY
IPC: B65D33/38
Filed: 1987-07-08
Abstract: A tube 10 is held in position between two superposed synthetic plastics walls of a bag by a light seam welding operation, with no special precautions taken in this step to make the joint leakproof. The bag and tube combination is then placed between the blocks of a mould, having confronting recesses and molten plastics material is injected to fill these recesses. The injected material forms a collar 22 which completely surrounds the tube. The bag film material on either side of the tube is melted to itself and to the tube wall, and the collar is securely attached in an encircling 22 configuration so precluding leakage. <IMAGE>
Patent GB-2195729-A (GB)
Title: Quick connectors
Inventor: NIX RICHARD ANDREW
IPC: F16L37/34
Filed: 1987-08-24
Abstract: A hydraulic control apparatus, having a master cylinder, a slave cylinder and a conduit connecting the master cylinder to the slave cylinder, is made of separate modular units interconnectable by leakproof connectors. The apparatus is prefilled with hydraulic fluid while the separate modular units are interconnected, and after filling the separate modular units are disconnected and shipped to a user, unconnected but filled with hydraulic fluid. Alternatively, the separate modular units may be individually filled with hydraulic fluid, and shipped to a user unconnected but each filled with hydraulic fluid. After installation on a utilization device, for example a motor vehicle, the complementary connector members are reconnected for placing the individual modular units in hydraulic fluid communication. The connectors take the form of complementary members which are arranged to open fluid passageway during connection. A one-way locking or retainer clip is disposed in one connector member for interlocking engagement with appropriate abutments in the other connector member for preventing separation of the members after coupling. The connector members may be disconnected by using an appropriate tool, or by providing a disconnect element built in one of the connector members, to enable disconnecting the members after installation of the apparatus on a motor vehicle for example, for the purpose of repair or replacement of components. <IMAGE>

Title: Sectional multi aperture bulk sampling spear
Inventor: CHRISTIAN DAVID HADDOW
IPC: G01N1/08
Filed: 1988-04-20
Abstract: A multi-aperture bulk sampling spear which may be split into two shorter sections, comprises two concentric tubes (1, 2) with a port at the lower end and a handle at the top. Halfway along the length of the concentric tubes there is a coupling (5) where the spear may be split into two shorter lengths. Within this coupling there is a means to secure the two halves of the outer tube together and also allow the turning motion exerted on the handle on the upper portion of the inner tube to be transmitted to the lower portion of the inner tube. The coupling will ensure that when the two lengths of the spear are assembled, the two portions of the inner tube will align themselves so that the orifices in them remain in line. The handle and point contain bearings which allow the inner tube to rotate within the outer tube whilst being restrained longitudinally. <IMAGE>

Title: Apparatus for pressurizing downhole well fluids in a subterranean well
Inventor: MENDEZ LUIS EDUARDO
IPC: E21B17/00
Filed: 1990-02-01
Abstract: A downhole pump is provided having characteristics that permit it to be installed in a subterranean well in order to pump well fluids at a substantial pressure to operate a downhole tool, such as an inflatable packer. The pump (30) is mechanically driven by motor means (60a, 60b, 60c, 60d) whose diameter permits insertion through the well and whose output characteristics are suitable for driving the pump means (30). A single mounting bracket (42) supports the motor means (60a, 60b, 60c, 60d) in a housing (10) and prevents counter rotation of tho motor stators. The motor means (60a, 60b, 60c, 60d) are immersed in a clean fluid inserted at the well surface and the clean fluid is maintained at the well hydrostatic pressure by a compensating piston (not shown). <IMAGE>

Title: Drum flying shear drive
Inventor: STYL PAVEL
IPC: B23D25/12
Filed: 1990-04-04
Abstract: The gear box (7) of the drum flying shears drive contains three non-circular gear wheels (10-12). The gear ratio between the intermediate non-circular drive wheel (10) and the left-hand non-circular driven wheel (11) driving the shears is given by the same relation as the gear ratio between the intermediate wheel and the right-hand wheel (12) driving the flywheel (8). Wheels 11 and 12 are angularly offset 180 degrees. Full energetic balance of rotating masses of the shear by the flywheel permits the drum flying shear to be designed with higher output and higher accuracy and substantial simplification of the mechanics. Electrical coupling of the shear motor (13) and the feeder motor (17) enables a higher degree of automation to be used. <IMAGE>

Title: Estimation of error of data values with increasing distance from control data points
Inventor: KOLLER GLENN ROBERT
IPC: G06T17/05
Filed: 1990-06-28
Abstract: In a method for estimating the error of data values with increasing distance from control data points, a gridded surface is generated from a plurality of control data points, and a distance grid is generated, from the same control data points, that has contours representative of the distance from the control data points. A residual grid is generated representative of the difference between the gridded surface and a reference surface, which was formed by a separate procedure from the plurality of control data points. The distance grid is then integrated with the residual grid to provide mean residual values representative of the error with increasing distance from control data points, and the output is plotted. This method can be utilized with a plurality of grid node interpolation algorithms and the outputs can be plotted side-by-side for the user to determine which grid node interpolation algorithm is best for mimicking the surface. <IMAGE>

Title: Unscrewing tool for thin wall cylindrical components
Inventor: KARP STEFAN
IPC: B25B13/50
Filed: 1991-03-20
Abstract: An unscrewing tool 6 having hardened slightly tapered circumferential serrations 8 is forced axially into the inside diameter 7 of a thin walled element on member 2 by turning nut 5 clockwise. Serration 8 is embedded onto inside diameter 7 to a sufficient depth that will enable an unscrewing torque applied to unscrewing tool 6 via spanner flats 9 to start the unscrewing process after which nut 5 is removed prior to completely unscrewing member 2. Separation of tool 6 from member 2 is achieved by inserting a spacer and partly screwing back member 2 onto member 1 until separation is realised. <IMAGE>

Title: Image forming method and apparatus for the same
Inventor: SAWAYAMA NOBORU
IPC: G03G15/01
Filed: 1991-04-26
Abstract: In a color copier, photosensors (41Y, 41M, 41C, 41BK) detect the amount of toner deposition on a reference pattern on a photoconductive drum (24Y, 24M, 24C, 24BK) and a signal is outputted to image processing section (12). A bias for development on sleeves (37) is changed by section (12) so as to maintain the output of the photosensor constant, so that the effective bias remains constant relative to the charge potential on the photoconductive element. Alternatively, section (12) can also change charge potential to chargers (25), the amount of exposure light from exposure unit (22) or more than one of these variables. This maintains the density of a predetermined reference pattern used to sense an image density constant despite the change in, for example, the reflection characteristic of the photoconductive drum. <IMAGE>
