Patent CA-2550957-C (CA)
Inventor: BASLER HERMANN
IPC: E21B19/16
Filed: 2006-06-26
Granted: 2014-05-27
Abstract: An open-throat power tong for making up or breaking apart an oilfield tubular connection, includes a cage plate lock system. The lock system connected to each cage plate extends across the space provided by the open throat in the cage plate when locked in the closed position. This provides support for the cage plates, resisting their tendency for expansion. The cage plates are mounted on the ring gear for rotation about a common center. The support provided to the cage plates for resisting expansion is communicated to the ring gear, thus providing support to the ring gear against expansion.

Title: Advance of pipe elements in the ground
Inventor: TRUMPI STEFAN
IPC: E21D9/00
Filed: 2005-02-17
Granted: 2012-06-12
Abstract: The aim of the invention is to advance pipe elements (18) for constructing an elongate structure in a soft, stony, rocky, and/or monolithic ground. Said aim is achieved by determining the force of advancement (40), the eccentricity (52) thereof in relation to the neutral axis (N), and/or the direction of advancement (28) with the aid of a pressing device (24) and extension elements (44) which are filled with fluid and are disposed on the face of the joints (70) of the tubing (14). The fluid pressure (p) is measured in at least one portion of the extension elements (44) which extends along the entire length of the tubing (14), and/or the deformation is measured in some of the joints (70). The force of advancement (40) and the eccentricity (52) are calculated from said parameters, and the values are stored and/or are compared to stored standard values. According to a variant, the eccentricity (52) is calculated, and the values are converted into control commands for the pressing device (24) and/or the individual fluid supply to or the individual fluid discharge from the extension elements (44).

Title: User authentication system and method for a communications network
Inventor: KE ZENG
IPC: H04L9/32
Filed: 2006-11-16
Granted: 2011-11-01
Abstract: A user authentication system and method for a communications network is provided. The credential authority publishes an accumulator and issues tokens and credentials to the users who are authorized to access a service. The user computes by himself a derived credential based on the credential issued by the credential authority, and proves to the verifier using the derived credential. If a new user is authorized, other users and the verifier need not update any data. If a user ever authorized is banned, i.e., his/her token is revoked, the credential authority computes the updated accumulator based on the token issued to the banned user, and publishes a revocation increment data comprising the updated accumulator and the increment data about the revoked token. Other users compute their updated credentials by themselves based on the updated revocation increment data received. The revocation increment data can be published in several forms, and propagated among the credential authority, the users and the verifiers quickly.

Abstract: A balloon for a dilation catheter, produced with a method that includes the steps of: (i) positioning a tube in a preconditioned mold; (ii) expanding the tube in a preconditioned mold to form a parison; (iii) positioning the parison in a balloon mold; and (iv) expanding the parison within the balloon mold to form the balloon. The tube is initially expanded into a parison in the preconditioned mold. Subsequently, the parison is expanded into a balloon in the balloon mold. Because of this unique manufacturing process, polyester block copolymers can be formed into balloons. Some of these polyester block copolymers could not be formed into a balloon using prior art blow molding processes. The resulting balloon exhibits superior characteristics, including relatively thin and consistent walls, soft texture, low uninflated crossing profile, expansion in a predictable fashion, and good tensile strength.

Title: Needle shielding device
Inventor: ERSKINE TIMOTHY J
IPC: A61M5/00
Filed: 2006-03-06
Granted: 2014-05-06
Abstract: A needle assembly with a needle shield is disclosed. The shield includes a lumen slidable on the needle, a holder and a needle blocking object which moves at least partially into the lumen in order to block distal movement of the needle. A spring biases the blocking object towards the needle axis.  Proximal movement of the needle relative to the shield is limited by a restraint in the form of a discontinuity on the needle which abuts the shield, a tether or a tube abutting the needle hub. When the needle shield moves from a non-shielding position to a shielding position, the needle blocking object moves at least partially into the lumen. The needle blocking object is radially and axially constrained in the shielding position. The holder also prevents radial, longitudinal and circumferential movement of the blocking object. In one embodiment, the needle blocking object is a ball. A catheter adapter and tube may be threaded over the needle. The needle blocking object may also lock the catheter adapter to the needle shield, allowing it to be released only when the needle is shielded.
