Класс МПК E21B 43/12 № заявки PCT/AU1988/000378 Заявитель BASTER, Lawrence, Reginald Изобретатель BASTER, Lawrence, Reginald

A mining installation and method for recovery of minerals from a below ground deposit in which at least two bore holes (32, 34) whic are mutually spaced and extend into the deposit, the bore holes including: a) at least one bore hole (32), referred to as pressurising bore, connectable to a source of pressurising liquid and having an outlet (42) within the deposit, and b) at least one further bore hole (34), referred to as a lift bore, having an inlet (44) thereto within the deposit, the lift bore having means (46) for discharging pressurised gas therein. The arrangement is such that pressurised liquid (A) supplied to the pressurising bore (32) is able to discharge from the outlet (42) to cause material of the deposit to move toward the lift bore (34) under hydraulicking action of the liquid, with the discharge of pressurised gas (B) in the lift bore providing an air-lift action on the material moved towards the lift bore (34) such that the material is raised in the lift bore (34).

3.WO/1989/006676THE USE OF POLYALPHAOLEFIN IN DOWNHOLE DRILLING

WO - 27.07.1989

Класс МПК C09K 8/02 № заявки PCT/US1989/000078 Заявитель COASTAL MUD INCORPORATED Изобретатель TRAHAN, David, O.

The composition of matter and application thereof in the present invention relates to the application of a synthetic hydrocarbon compound, a polyalphaolefin liquid, blended in various concentrations with chemical oil and water emulsifiers, thinners and oil and water surface tension reducers, the concentration of polyalphaolefin liquid to that of the remaining portion of the blend being no less than 5 %; blending the polyalphaolefin liquid and the emulsifiers in a blending tank containing water base drilling mud; circulating the blend of polyalphaolefin liquid and emulsifier with the water base drilling mud downhole, so that the blend of polyalphaolefin liquid, emulsifier and water base drilling mud lubricates the drill string or reduces the differential pressure between the wall of the borehole and the drill string so that the drill string is free to rotate and drilling may be undertaken with less drag or torque. In another application, the polyalphaolefin blended with the emulsifier serves as a spotting fluid in order to unstick drill pipe that has become stuck. In this method, the polyalphaolefin emulsifier blend is introduced into the borehole as a ''pill''; the pill is circulated downhole in the mud system through the annulus to the depth at which the pipe is stuck; the polyalphaolefin emulsifier blend acts on the differential forces between the wall mud cake and the pipe to reduce the differential pressure between the pipe and the formation, so that the pipe is freed and drilling is able to resume.

The invention relates to an assembly element (2, 2') for the forming of flat elements such as for example walls (1), floors or roofs with at least two board-like basic elements (3, 3') having spacers (4, 4', 5). The spacers (4, 4', 5) comprise spacer strips or individual spacer pieces separate from one another are secured between two board-like basic elements (3, 3'), in the region of the vertical long sides and substantially form a U-shaped groove or a U-shaped tongue. Such spacers (4, 4', 5) do not involve sectional rails and require no separate strip-like connecting elements for the connection of at least two assembly elements (2, 2').

7.WO/1982/001388FLEXIBLE TERMINAL POINT FOR LATTICE WORK CONSTRUCTIONS

WO - 29.04.1982

Класс МПК E02B 17/00 № заявки PCT/SE1981/000291 Заявитель SCANDING BYGGKONSULT AKTIEBOLAG Изобретатель HALVORSEN, Finn

A flexible terminal point, specially for lattice work constructions comprising a tube formed terminal means (5), which is secured to one of the bars (1), and which at its one end (7) receives the other bar (3) in a manner which allows limited flexibility. Through the tube-like terminal means (5) runs one or several tie-rods, by which the terminal means (5) is attached to the other bar, and by which the terminal means can be pretensioned, whereby load changes in the other bar (3) only to a lesser degree cause strain changes in the tie-rod (15) while the major part of the loads in the other bars (3) is taken up by the tube-like terminal means (5) which is set under compression forces. Coupling between terminal means (5) and the movable bar (3) is effected by means of a bearing socket via a rubber pad (13) or spherical surfaces in the terminal means (5) and movable bar (3). The tie-rod (15) can be formed as one or several tie-rods, steel cables, wires or such, which can be tensioned and locked by known methods for pretensioned constructions.

9.WO/1983/002693ENERGY CONVERSION SYSTEM

WO - 04.08.1983

Класс МПК H02K 44/08 № заявки PCT/US1983/000117 Заявитель COVER, John, H. Изобретатель COVER, John, H.

A system for converting one form of energy into an alternate form of energy by means of a low-temperature process. A liquid flow loop with two vertical columns (13, 15) that are interconnected at the top and bottom circulates a fluid. A convective flow of this fluid is established by heating the fluid in one of the columns and cooling the fluid in the other column to establish a weight differential between the fluid in the two columns (13, 15). An electric generator (101) is placed on this loop so that, as the fluid flows through the loop and through the generator (101), electrical energy is generated. This electrical energy is used to electrolize a second fluid, such as a solution of sulphuric acid, into gasses such as hydrogen and oxygen. The gasses so generated are used to increase the rate of flow of the fluid, and consequently the rate of electric energy production. In one embodiment, the gasses are injected into the rising column (13) of the fluid to increase the weight differential between the fluid in the two columns (13, 15) and enhance the convective flow of that fluid. These gasses, which contain chemical energy, are then removed from the loop at the top (71) of this column (13). Alternatively, the gasses can be accumulated at high pressure, and the pressure used to inject a volatile fluid into the loop.
