Patent CA-2234089-A1 (CA)
Inventor: KRUEGER R ERNST
IPC: E21B17/10
Filed: 1996-10-10
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).

Title: Method and apparatus for hydroforming metallic tube
Inventor: KOJIMA MASAYASU
IPC: B21D26/033
Filed: 1998-04-23
Abstract: A method and apparatus for hydroforming a metallic tube including the steps of: preliminarily expanding the metallic tube over an axial section longer than the length of the expanded portion of a final product as measured in the axial direction of the metallic tube; and compressing the preliminarily expanded portion in the axial direction of the metallic tube so as to form the shape of the expanded portion of the final product.          According to the method and apparatus of the invention, frictional resistance between the metallic tube and processing tools can be reduced, and moreover, the internal pressure within the metallic tube can be reduced during expansion processing.  Furthermore, the cost for the manufacture of metallic die is reduced, and in addition, yield is improved.

Abstract: An conference call reminder service is provided by automatically launching a call at a scheduled time to each of a plurality of invited participants (16, 17, 18, and 20) whose identity has been established, typically via the participant's telephone number. After answering, each invited participant's call is bridged, either immediately, or after validation of a participant code entered by the participant following a prompt to enter such a code.

Inventor: BENE BERNARD
IPC: A61M1/14
Filed: 1998-08-31
Abstract: The procedure for regulating the concentration of sodium in a dialysis fluid at a predetermined level so that the fluid inside the patient tends towards a desired concentration as the patient's blood and dialysis fluid are circulated on either side of a semi-permeable membrane (4) in a dialyser (1) consists of determining the concentration of sodium in the dialysis fluid, the desired concentration, the perfusion flow rate and the concentration in the perfusion fluid and adjusting the dialysis fluid concentration accordingly. The concentration of sodium in the dialysis fluid is determined from a set formula based on the desired concentration, the concentration in the perfusion fluid, the fluid flow rate and the dialyser separating capacity. The separating capacity is determined by circulating at least two dialysis fluids with different conductivities, taking two or more conductivity measurements before and after the dialyser, and calculating the separation capacity from the values obtained, using a second formula.

Filed: 1997-06-02
Abstract: A method and a plant for purification and other treatment of circulating water in water-based heating/cooling plants, district heating plants etc. The water is lead into the upper area of a tank (10) containing a "stack of layers" comprising material layers (44, 46, 48, 50, 52, 54) of granulated filtration materials and chemical reaction materials, in which the densities of the layers increase by the layer downwards, whereby treated water is let out at the lower area of the tank (10) and is returned to the water-based plant. The individual granulated materials of such a stack of layers may be washed clean of sludge and corrosion particles etc. by directing a water flow in the upward direction from the bottom of the tank (10). The individual granulated filtration/reaction materials as the backwashing is finished will settle - because of their mutually differing density values - into their respective layers (44, 46, 48, 50, 52, 54) at the original levels.

Title: Aremac--based means and apparatus for interaction with computer, or one or more other people, through a camera
Inventor: MANN STEVE
IPC: G03B29/00
Filed: 1998-12-24
Abstract: A new kind of display means and apparatus called an aremac is provided.  The aremac may either be worn upon the body, such as in a pair of eyeglasses, where it can direct light into an eye of the wearer of the apparatus, or it may be located together with a fixed camera to direct light onto a three dimensional scene or objects. The typical application of the aremac is that of collaborative photography, in which a remote director assists a photographer in composing a picture, or arranging lighting in a photographic studio while the remote director remotely views the scene through the photographer's camera.  In a wearable embodiment, the camera is effectively imaged inside an eye of the wearer so that the remote director can view the light rays passing through an eye of the wearer of the apparatus and the director can write on the retina of the wearer of the apparatus by pointing a laser beam at the screen in the director's office, which teleoperates a miniature laser beam directed through the wearer's eye lens onto the retina of an eye of the wearer in such a manner that when the director points at an object in the scene, the wearer of the apparatus sees a red dot at the corresponding location on that same object.  In another embodiment, the remote director can point to objects in the photographer's studio by pointing a laser beam at a projection screen which displays images of these objects in the photographer's studio, where the director's laser pointer remotely controls a teleoperated laser pointer in the photographer's studio.
