Title: Method for providing solids-free production from heavy oil reservoirs
Inventor: JENNINGS ALFRED R
IPC: E21B43/24
Filed: 1990-11-09
Abstract: A method for controlling formation fines when producing heavy oil from an unconsolidated sand formation where at least two wells are utilized.  Both wells are perforated and hydraulically fractured at a lower interval via a viscous gel fluid having a sized and high temperature resistant proppant therein.  The proppant is a size sufficient to filter fines from the oil, thereby keeping the fracture clear.  Cyclic steam-flooding and oil production are conducted in one well, while the other is shut-in.  This sequence is continued until steam breaks through at the lower interval from a first well into a second well.  Afterwards, production packers with knock-out plugs are used to isolate the lower interval of both wells.          Cyclic steam injection and oil production are continued in the upper interval of both wells.  Subsequently, both wells are shut-in and production strings are directed to the lower formation interval through the knock-out plugs.  Steam is then injected down the lower level of both wells and oil is produced from the upper level through the annuli of both wells.

Abstract: ABSTRACT A linear motion ball bearing is disclosed for providing relative linear motion in combination with a shaft.   A housing has an axially elongated opening therethrough and an axially elongated generally tubular shaped ball retainer is positioned within the housing opening and defines a plurality of endless ball loops therein extending generally in the axial direction of the retainer.  The retainer has a radially inner surface and a radially outer surface and the ball loops are spaced generally circumferentially about the retainer.  Each loop contains a plurality of balls and has a first ball duct for a row of loaded balls and a second ball duct for a row of unloaded balls.  Each first ball duct is open through the radially inner and radially outer surfaces of the cage, and each ball loop is arranged with the first ball duct next adjacent the first ball duct in the adjacent ball loop along one axially extending side and the second ball duct wherein adjacent the second ball duct in the next adjacent ball loop along the other axially extending side.  The housing defines a land opposite each pair of adjacent first ball ducts and extending radially inward, each land extending sufficiently radially inward and being of sufficient circumferential dimension to support the loaded balls of adjacent pairs of the first ball ducts and having a contoured relatively smooth surface for accommodating the loaded balls positioned within the corresponding opposed pair of respective first ball ducts of respectively adjacent ball loops.  A uniquely shaped complex ball support surface connects each pair of ball ducts while maintaining constant floor to ceiling height about the balls to provide smooth, quiet operation of the bearing so as to combine with the uniform loaded ball arrangement to provide a unique bearing having improved load life performance and substantially quiet characteristics, while simplifying the manufacturing procedures.

Title: Semiconductor capacitor circuit
Inventor: AUSTIN KENNETH
IPC: G11C27/02
Filed: 1991-03-28
Abstract: SEMICONDUCTOR CAPACITOR CIRCUIT                ABSTRACT OF THE DISCLOSURE       This invention relates to semiconductor integrated circuits concerned with the realisation of different value capacitive components of a semiconductor chip by means of programming control arrangements.  Programmable capacitors are implemented using a capacitive multiplier technique.          Programmable capacitors comprise essentially three elements, a capacitor (C1) and one or two capacitor multipliers.          Capacitor (C1) is connected to the output of a first buffer circuit while programmable resistors (RP1 and RP2) are connected in series between the input and output of the buffer, an output being taken from the junction between the first and second programmable resistors.  By this arrangement of components, the ratio of the set values of the two programmable resistors (RP2 and RP1) determines the amount by which the capacitor (C1) value is multiplied.  An overall effective capacitance value equal to (RP2/RP1) x C1 may be achieved.  The final effective capacitance with two multipliers approximates to (RP2/RP1) x (RP4/RP3) x C1.  The value of programmable resistor RP1 is adjusted in accordance with an analogue reference signal produced by a compensating circuit to compensate for the manufacturing/processing variations of capacitor C1.

Abstract: ABSTRACT OF THE DISCLOSURE           A portable fence system including a snow fence panel having a wood frame of 2" x 6" posts bolted together at the corners, with a 4-foot wide strip of plastic snow fence material pulled taut across the center.  Each panel is 8 feet long, with a height of 6'-8" or 8'-0", depending upon the application.  In both cases the geometry of the frame is optimized for maximum snow trapping efficiency and maximum snow storage, and an opening at the bottom is optimized to eliminate the tendency for snow deposition at the fence.  Panels are connected to one another by rebar pins passing through specially designed rotatably mounted U-clips, which also provide attachment to rebar anchors driven into the ground.          The U-clip-and-pin connections allow rapid installation and take-down,  and  add  flexibility  needed  for proper  installation  in irregular terrain.  Panels can be overlapped at either the top or bottom as required to limit space between panels to 1 1/2", which improves trapping efficiency.

Abstract: A process is described for the partial desulphurization roasting of a variety of zinc bearing sulphide ores or concentrates by adjusting the roaster temperature and residence time in the roaster thus providing an oxygen deficient atmosphere so that the required amount of sulphide retention is maintained. The obtained calcine or calcines are subsequently subject to various chemical and/or physical separation process steps to separate the unreacted sulphides which are, according to certain embodiments of the process, then dead roasted and treated for zinc recovery. In another embodiment, the separated unreacted sulphides are again partially desulphurized in an oxygen deficient atmosphere for subsequent treatment to recover zinc, lead and precious metals. The chemical separation process steps include aqueous sulphur dioxide treatment, dilute sulphuric acid solution treatment and treatment with dilute sulphuric acid containing sulphur dioxide in solution, all conducted in the temperature range of 50 to 75·C. Physical separation process steps include one or more of the flotation and magnetic separation techniques although other physical separation steps may also apply in some instances.
