Patent CA-2216498-A1 (CA)
Title: Floating cushion sub
Inventor: SECORD DOUGLAS CECIL
IPC: E21B17/07
Filed: 1997-09-25
Abstract: A cushion sub for absorbing both axial and torsional vibration in modern drilling techniques. The cushion sub includes an outer casing connectable at one end to a section of a drill string, usually the upper section being actually the output of the rotary drive, and an inner piston reciprocally mounted in a cylinder within the casing, the piston has a shaft projecting from the other end of the casing connectable to another section of the drill string. The cylinder includes a first cushion device at opposite ends thereof for engagement by the piston to absorb axial vibrations and thereby prevent their transmission between the piston and the cylinder. A spline type connection prevents relative rotation between the piston and the cylinder. The cylinder is mounted for arcuate turning within the casing, but the cylinder has vanes which are interposed between vanes fixed to the casing, and elastomeric material between the vanes of the cylinder and the vanes of the casing absorbs torsional vibrations being transmitted between the cylinder and the casing. An outer surface of the cylinder may be spaced radially inward from an inner surface of the casing to form a closed chamber therebetween containing the interspaced vanes and the elastomeric material between the vanes. The elastomeric material is preferably formed in situ as an integral mass in the chamber by pouring the elastomeric material in a fluid state into the chamber. The cushion sub is of a compact nature with long wear characteristics and is capable of handling the types of forces experienced in advanced drilling techniques and preventing the torsional and axial vibrations developed downhole from being transmitted to the rotary drive.

Abstract: L'invention porte sur un procédé in vivo visant à apporter un agent diagnostique ou thérapeutique à un site cible chez un mammifère. Dans le cadre de ce procédé, on apporte à un site cible une espèce ciblante ayant la possibilité de s'accumuler sur celui-ci, l'espèce ciblante comprenant une fraction ciblante et un agent diagnostique ou thérapeutique ou un site de liaison pour un conjugat d'agent diagnostique ou thérapeutique administré ensuite, la fraction ciblante étant pourvue d'un site de liaison primaire au moyen duquel elle se lie de manière spécifique à la cible. On améliore l'espèce ciblante en injectant dans le système circulatoire du mammifère un agent éclaircissant qui se fixe au site primaire de liaison de celle-ci, l'espèce ciblante primaire non localisée étant retirée de la circulation. Ce procédé s'avère particulièrement utile pour des techniques de pré-ciblage puisque l'agent éclaircissant n'élimine pas l'espèce ciblante primaire ni ne bloque des sites secondaires de liaison de celle-ci.

Title: A procedure for calibrating a breathalyser
IPC: G01N33/497
Filed: 1997-12-31
Abstract: The present invention relates to a procedure for calibrating a breathalyser (7) by means of a calibrating gas generator (1) with a fluid reservoir (2) for an aqueous ethanol solution (3), and air supply devices, this being designed so as to allow air to percolate through the ethanol solution and conduct gas from the atmosphere above the ethanol solution to the breathalyser (7). In order to equalize the temperature dependency of the ethanol concentration in the gas phase without the need to carry out thermal stabilisation, the process is conducted in the following steps: measurement of the temperature of the ethanol solution by a thermometer (8) and generation of an electrical signal that represents the temperature; reception of the electrical signal in a sender unit (9) and passage of the electrical signal, or a signal processed therefrom, to the breathalyser (7) and to its electronic evaluation unit, automatic conversion in the electronic evaluation unit of the test reading of the breathalyser (7) to the test result that is to be anticipated at a given reference temperature, using a predetermined dependency of the temperature of the aqueous ethanol solution obtained from the electrical signal or from the signal processed therefrom and the given reference temperature, and evaluation of the test reading anticipated at the given reference temperature in order to calibrate the breathalyser (7).

Abstract: A sorting apparatus includes a first grating of spaced parallel bars and a second grating of spaced parallel bars positioned parallel to the first grating. Relative lateral movement of the first grating and the second grating alters the lateral spacing between the parallel bars of the first grating in relation to the parallel bars of the second grating. This enables rocks to be sorted into three piles; a first pile of rocks that will pass through when openings in the first grating and second grating are out of register, a second pile of rocks that will pass through only when openings in the first grating and second grating are in register, and a third pile of rocks that will not pass through.

Inventor: SERGEY SCOVOROD KO N
IPC: G01B11/30
Filed: 1998-09-15
Abstract: These present inventions represent optical devices for remote measurement of one-dimension roughness. These devices allow the measurement of the roughness automatically with the use of a computer.      The first method for the measurement:     The interference one-dimension pattern is formed on the rough surface. The direction of a roughness coincides with the direction of the interference pattern. If the bandwidth in the interference pattern is equal to the period of the roughness, then the light reflected from a rough surface has maximum or minimum intensity. By changing bandwidth in interference pattern and synchronously measuring intensity of the light reflected from a rough surface, it is possible to obtain the information about bandwidth in the interference pattern when the signal has a maximum or minimum intensity.      The second method for the measurement:  The light from a point source goes on a rough surface and is reflected by it. Reflected light has defined distribution depending on the roughness size. To measure the roughness size it is necessary to compare intensities of reflected light in specular direction and any additional direction.
