Title: Displacing hydrocarbons in subterranean reservoirs
Inventor: YELLIG WILLIAM FRANCIS
IPC: E21B43/16
Filed: 1984-07-04
Abstract: Injectivity losses in alternate displacing fluid-aqueous fluid injections into an oil-bearing reservoir can be reduced through injection of a secondary displacing fluid in conjunction with the first displacing fluid injection cycle. The secondary displacing fluids reduce residual oil saturation near the injection wells to prevent adverse effects on relative permeability to aqueous fluid flow, which can occur. Fluids useful as the secondary displacing fluid of the invention include nitrogen, methane, ethane, propane, benzene, and refined oil.

Title: Ultra-high pressure abrasive jet cutting of glass
Inventor: HERRINGTON RICHARD ALVIN
IPC: C03B33/10
Filed: 1985-09-03
Abstract: A system readily cuts intricate interior patterns from, as well as make simple cuts across, glass blanks S of various thicknesses at increased speed by means of an ultra-high pressure abrasive fluid jet. A highly collimated fluid stream or jet 14, into which abrasive particles are aspirated, is directed against the glass from a pressurized source 33. For initial penetration of the glass within the interior of the blank, the pressurized source is maintained at a first pressure level, so that the glass is initially penetrated without fracturing or undue chipping at the point of penetration and whereby the abrasive fluid stream may be advanced along the desired path relative to the glass at a first speed such as to sever the glass. After initial penetration by the abrasive jet the pressure level of the pressurized source of fluid is significantly increased, enabling the line speed of the fluid jet relative to the glass to be increased while still severing the glass and producing cut edges of high quality. <IMAGE>
Patent GB-2181055-A (GB)
Title: Disposable syringe
Inventor: COLGATE DAVID JOHN
IPC: A61M5/28
Filed: 1985-10-01
Abstract: A resiliently compressible variable volume casing having particular application as a disposable syringe. The casing (1) defines a chamber (1a) and is provided at one end region thereof with an aperture (2) for permitting transfer of a substance to and from the chamber. The casing is in the form of a bellows and has a wall including a plurality of fold regions (6) between which are respective bellows portions (7, 7a). The casing is configured so that there is a substantial reduction in ''dead space'' or the air entrapped in the casing, when the bellows is compressed. This is achieved by one or more of the following: 1) forming the bellows portions so that when the bellows is compressed there is a bellows portion the periphery of which lies wholly within or wholly without the peripheries of its adjacent bellows portions; 2) providing the casing with a member mounted with respect to the casing and such that, when the bellows is compressed, the member occupies a major portion of the internal volume of the casing; and 3) forming the bellows portions each with concave and convex surface so that a concave surface of one bellows portion mates with the convex surface of the adjacent bellows portions. The reduction of ''dead space'' in the compressed casing, and the almost complete elimination of air which follows, mean that the casing is particularly useful for the storage of substances for which contact of air is to be avoided. The aperture may be formed as a hollow needle receiving portion particularly adapted to receive a hypodermic needle, so that the casing may be used as a syringe either to remove body fluids or to administer medication.
Patent GB-2167692-A (GB)
Title: Electric motors
Inventor: CLARKE DEREK ARTHUR
IPC: H02K15/06
Filed: 1985-11-06
Abstract: In order to fit the field coils 69 into the slots in the core 16 of an electric motor stator it is usual to insert them via one slot end. To protect the wire from the lamination-caused jagged slot mouth edges it is necessary to provide each with a (temporary) cover known as a "guide blade" 15. In operation, the blades are pushed all the way into place on the core ridges (the mouth edges), the coils are then pushed into place in the core slots, and then the blades are withdrawn. The present invention proposes quite a different arrangement. Specifically, it suggests that, using a set of much shorter blades - merely long enough, in fact, to accommodate the depth of wire (the throat) in the coil (plus a little more) - both the blades and the wire should be pushed together into and through the core slots. <IMAGE>

Title: Controlling boundary layer
Inventor: RAGHUNATHAN SRINIVASAN
IPC: B64C23/04
Filed: 1986-01-06
Abstract: A buffet breather system for aerofoils is used to alleviate buffet and energy losses caused by separation at a shock of subsonic and transonic airflow speeds. A network of breather orifices 12, 13 in the surface may be connected together, e.g. by chamber 14, so as to permit flow from one region to another. The orifices may be forward facing, normal or backward facing holes, or any suitable combination. The intensity of shock is also decreased. The improvement in efficiency can be achieved with very low levels of aerofoil porosity.   <IMAGE>
