Patent CA-2234089-C (CA)
Inventor: MOORE N BRUCE
IPC: E21B17/10

Granted: 2004-03-02
Abstract: A drill pipe/casing protector assembly (18) for an underground drilling system comprises a well bore in an underground formation, a fixed tubular casing (16) installed in the well bore (14), a rotary drill pipe (12) extending through the casing (16) and having an O.D. spaced from an I.D. of casing (or well bore) during normal drilling operation, and a protective sleeve (18) mounted around the drill pipe and spaced from the I.D. of the casing, and upper and lower thrust bearings (22, 24) affixed to the drill pipe above, and below the sleeve to retain the sleeve in a fixed axial position on the drill pipe. The sleeve (18) contacts the I.D. of the casing when the drill pipe (12) deflects off-center to protect the casing from contact with the drill pipe or its tool joints during rotation of the drill pipe. Axial grooves (26) in an I.D. wall of the sleeve allow fluid under pressure to circulate through a space formed between the I.D. of the sleeve (18) and the O.D. of the drill pipe. Generally flat bearing surface regions (32) on the I.D. wall of the sleeve between adjacent grooves (26) are arranged in a polygon configuration for tangentially contacting the O.D. of the drill pipe around the sleeve I.D. The sleeve (18) separates from the O.D. of the drill pipe upon circulation of a fluid film under pressure between the sleeve (18) and the drill pipe (12) to produce a fluid bearing effect with reduced frictional drag. End slots at the top and the bottom annular end walls of the sleeve provide enhanced fluid bearing effects in the clearance regions between the sleeve and the adjacent thrust bearings (22, 24).

Abstract: New types of fiberoptic microbend sensors are in the form of flexible tapes wherein single or multiple layers of mechanically tough flexible tapes form two outside surfaces of the sensors including between them one or more continuous elongated optical fibers, a variety of monofilaments, wires, threads, meshes, ribbons and or like elements to act as deformers to the optical fiber and sufficient adhesive material to form a permanent flexible tape structure. Additional layers of film,optical fibers, and/or deformer elements may be included to augment or modify the intensity of light that issues from the output end of the optical fibers when they are illuminated at their input end while the surface films of the sensor are subjected to pressure, such as when the sensors are used to weight or detect passage of automobiles. Detection or measuring systems and methods using the flexible sensor tapes are disclosed.

Title: Novel elastomer composites, method and apparatus
Inventor: CHUNG BIN
IPC: B29B7/30
Filed: 1997-03-25
Granted: 2008-08-05
Abstract: Elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like. Novel elastomer composites are produced. Such novel elastomer composites may be cured or uncured, and combine material properties, such as choice of filler, elastomer, level of filler loading, and macro-dispersion, not previously achieved.

Granted: 2004-11-02
Abstract: A continuous method using a pressurized flow of liquefied carbon dioxide is described to reduce microbial and/or enzymatic activity in a liquid product. A flow of liquefied carbon dioxide is combined with a pressurized flow of the liquid product. The pressure and temperature in the flow regions are maintained at a level which is sufficient to keep the carbon dioxide in a continuous liquid state, but which does not freeze the liquid product.      The pressurized mixture of the carbon dioxide and liquid product flows through a reaction zone for a sufficient time to reduce harmful microorganisms and/or inactivate undesirable enzymes and then enters a plurality of expansion stages wherein the pressure of the mixture flow is sufficiently decreased to vaporize the carbon dioxide for separation from the liquid product. Heat is applied in at least some of the expansion stages to prevent a cooling of the mixture flow to the freezing point of the liquid product. Heat may be applied to control the temperature of the liquid product so that it does not exceed a temperature at which deleterious effects are experienced.

Title: Encryption/decryption method and authentication method using multiple-affine key system and apparatuses using the same
Inventor: SUZUKI SHUICHI
IPC: H04L9/18
Filed: 1999-12-02
Granted: 2004-09-14
Abstract: In the encryption/decryption method, a random number sequence {r i} is generated on the basis of a given key system K and encryption is performed by an exclusive OR of the random number sequence {r i} with a plain text. Further, the key system K is automatically sequentially rewritten into a series of new key systems each tame when the number "c" of use times of the key system reaches a predetermined number "n" and encryption of plain texts thereafter is continued while generating random numbers using the series of the rewritten key systems. Likewise, in decryption as well, since decryption is performed using a key system automatically rewritten each time when the number "c" of use times reaches a predetermined number "n", a third party cannot reproduce the key system and therefore cannot decipher a cipher text.
