Abstract: ABSTRACT OF THE DISCLOSURE          Subterranean oil and gas producing formations are fractured by providing one or more combustion gas generating units using rocket fuel type propellants disposed in a well casing at preselected depths. The well casing is filled with a compressible hydraulic fracturing fluid comprising a mixture of liquid, compressed gas, and propant material and precompressed to a pressure of about 1,000 psi or more greater than the fracture extension pressure at the depth of the zone to be fractured. At least one of the gas generating units is equipped with perforating shaped charges to form fluid exit perforations at, the selected depth of the fracture zone. The gas generating units are simultaneously ignited to generate combustion gasses and perforate the well casing. The perforated zone is fractured by the rapid outflow of an initial charge of sand free combustion gas at the compression pressure followed by a charge of fracturing fluid laden with propant material and then a second charge of combustion gas. The column of precompressed fracturing fluid is discharged into the formation until the hydraulic extension pressure is reached and eventually the perforations sanded off.

Abstract: LOCKING ARRANGEMENT, ESPECIALLY FOR FLUIDS UNDER HIGH PRESSURE, AND USE OF THE APPARATUS              ABSTRACT OF THE DISCLOSURE      Locking arrangement for fluids under high pressure.          The housing of the apparatus has a cylindrical hollow space, into which an inlet, an outlet and a relief channel lead.  A pair of pistons, connected by a rod may be pushed back and forth between a closed position and an open position by means of two pneumatically operable, single-action piston-cylinder units between a closed position and open position.  In the closed position one of the pistons of the pair of pistons closes the connecting path between the inlet channel and the outlet channel and the other piston opens up the connecting path between the outlet channel and the relief channel.          In the open positon, one of the pistons opens up the connecting path between the inlet channel and the outlet channel, and the other piston closes the connecting path between the outlet and the relief channel.  In both positions the part spaces of the cylindrical hollow space, adjacent to the shifting path of the pair of pistons, are connected with the relief channel.  The apparatus closes and opens within a few milliseconds and also operates reliably in the case of abrasive fluids.

Abstract: A method of setting a code in such a manner that great security against unwanted discovery of the code at the moment of setting is achieved. An exemplary embodiment includes a display 1, on which the current code value 4 can be read when the eyes 11 of the user are located in an imaginary readability space 10, the dimensions and positioning of which are adapted to the natural eye position of the legal user. The code value 4, which is initially random, can be changed relatively to a desired value by using forms of input members 3 and 5 which are themselves without code information. Owing to the limited readability space, only the legal user can read the code, and owing to the fact that the code value can only be changed relatively from a random initial value, the code cannot be deduced from the hand movements of the user. The invention is a solution to a real security problem connected with the use of payment cards, but can also be used for other forms of information input where great anonymity is required. <IMAGE>
