Patent JP-H06102952-B2 (JP)
IPC: E21B31/107
Filed: 1987-06-02
Abstract: A drilling jar (100) includes a swivel (20) which allows the drilling jar to operate substantially independently of any right hand torque that becomes trapped in the drill string. The swivel (20) includes a bearing cage (9) that engages the polished stem (4) of the drilling jar to the jay stem (5) of the drilling jar. This bearing cage (9) holds a number of bearings (10) against the jay stem (5) and the polished stem (4). The swivel (20) allows the jay stem (5) to rotate substantially independently of the polished stem (4). The drilling jar may further include splines (8) formed onto the outer surface of the polished stem (4) for transmitting torque from the polished stem (4) to the barrel (1) of the drilling jar without simultaneously transmitting torque from the polished stem (4) to the jay stem (5). In addition, the drilling jar may include floating pistons (11,12) that are circumferentially engaged to the polished stem (4) and the washpipe (7) that effect the upper and lower seals on the drilling jar and allow the internal pressure inside the tool to be equalized with the internal and external pressures of the drill string.

Abstract: Disclosed is a process and device for facilitating the differentiation of particles in a medium. The particles, which belong to at least two different groups of particles, are enclosed in a chamber bounded by electrodes which produce a rotating electrical field. A means for producing two rotating electrical fields having opposite directions of rotation and variable rotational frequency is provided to be attached to the electrodes. The particles exposed to the rotating electrical field forces with opposite directions of rotation can be differentiated on the basis of their rotational behavior.

Abstract: A pressure relief panel assembly (20) for rupture discs, explosion vents and the like has a plurality of frangible panel portions (140, 44, 50) which burst at different pressures to present a pressure relieving aperture having a cross-sectional area which varies in accordance with the number of panel portions (40, 44, 50) which have ruptured. In one embodiment of the invention, the assembly comprises two frangible panels (26, 30) positioned in face-to-face relationship in covering disposition to a vent opening, and the innermost panel has an orifice which functions as a pressure relieving aperture once the outermost panel ruptures; subsequently, further build up of pressure causes the innermost panel to burst and present a pressure relieving aperture larger than the orifice so that the structure to be protected is fully vented. In certain forms of the invention, a discontinuous pattern of perforated lines of weakness in the innermost panel serve as pressure relieving apertures once the outermost panel ruptures. In another embodiment, the assembly comprises a single panel (125) having one set of weakness lines (142) defining a first frangible panel portion (140) and a second set of weakness lines (142) surrounding the first set and defining a second frangible panel portion (144).

Abstract: PURPOSE:To prevent the separation of plies of a belt layer by a method in which a triangle belt layer is made up of 4 plies with steel cords arranged at given angles for each, and a high-elastic cord protective layer is interposed between both ends of the second and third plies. CONSTITUTION:A belt layer 10 is made up by orderly laminating the first - the fourth plies 1-14 wherein steel cords are each arranged at 50-70 deg., 10-30 deg., -10--30 deg., and -10--30 deg. to the circumferential direction of tire and the first ply 11 in proximity to carcass. A high-elastic cord protective layer 15 almost in parallel with the circumferential direction is interposed with a width W0 of 5-100mm. on both ends of the second and third plies 12 and 13. The distance L between the outside end 15a of the layer 15 and the end 12a of the second ply is set up to about 10mm. or less, and the width W2 of the second ply is set to 100-130% of that W3 of the third ply and the width W3 of the third ply is made wider than that W1 of the first ply. The separation of the plies can thus be prevented.

Abstract: An analysis system for analysing coal or other material causes the material (3) to be bombarded with neutrons (2) from a source (1), and this generates gamma rays (11,12,13) from the material (3) which are detected by a detector (4). The detector has scintillators (5,6) which generate light when a gamma ray is detected, the light being detected by photomultipliers (8,9). Each gamma ray generates two other gamma rays, which may both be wholly absorbed in one or the other scintillator (5,6) or one absorbed in one scintillator and one in the other. By analysing these events, the spectrum of gamma rays may be obtained, giving the composition of the material. One preferred detector has an array of scintillators and coincident gamma ray detection events in three adjacent scintillators detected.

Abstract: In electrochemical flow through sensors comprising at least one cell for the passage of a fluid for analysis therethrough, the method of optimizing the flow pattern and signal-to-noise ratio comprising the steps of loading the cell under high pressure with a first fluid which will set to a solid material; before the solid material solidifies, causing a second fluid immiscible with the first fluid to flow through the cell at low pressure to find the optimum flow path therethrough; and, with the immiscible fluid in the cell, allowing the first fluid to solidify. Bandspreading is improved because any offset, junctions, or potential traps that would induce drag or trapping effects on a test fluid flowing through the cell are reduced in size and/or number and/or eliminated. The signal-to-noise is improved as the result of filling spaces in the cell that may contribute to noise but do not contribute significantly to useful signal because of their location relative to the optimum flow path.

Abstract: A method and a sealable, sterilizable vessel for detecting the presence of microorganisms in a specimen, the vessel containing a liquid culture medium and a sensor with an indicator medium therein. A gas permeable membrane with a gas impermeable removable seal thereon are provided in a wall of the vessel. If the microorganism to be detected is an anaerobic organism, then the gas impermeable seal is left in place. If the microorganism to be detected is an aerobic organism, then the gas impermeable seal is removed so as to allow the passage of oxygen into the vessel. In a preferred embodiment, the gas permeable membrane allows the passage of oxygen into the vessel while at least partly restricting the passage of carbon dioxide to outside of the vessel. Changes in the indicator medium resulting from a change in gas production (CO2, NH2, H2S, etc.), volatile acid production or pH concentration in the medium, are detected from outside the vessel.
