Abstract: A Christmas tree (16) is described which is based on a dual bore sub-sea test tree. The Christmas tree consists of a Christmas tree housing (56), which connects to a wellhead (44), a Christmas tree valve block assembly (62) disposed in the housing (56) and a tree cap (84) which connects to the housing (56) and valve block assembly (62). In a preferred embodiment the valve block assembly (62) has a main production bore (70) with two valves (72, 74) in series and two auxiliary bores (76, 96). One auxiliary bore (96) has a valve (98) for facilitating control of the annulus bore (96) whereas the other annulus bore (76) has no valve and provides a pathway for an electrical submersible cable (66) to a pump. The valves (72, 74, 98) are actuatable via control from an umbilical (94) and provide the facility to seal the production and annulus access bores to meet statutory requirements. A tubing hanger is not required.

Title: Equipment for crystal growth and crystal-growing method using the same
Inventor: SANJOH AKIRA
IPC: C30B7/00
Filed: 1997-07-08
Abstract: Provided are an apparatus and a method which can accelerate crystallization of a biological macromolecule such as protein. A plurality of solution storage parts (12a, 12b, 12c, 12d, 14) are formed on a silicon substrate whose valence electrons are controlled by controlling the concentration and/or the type of impurity. These solution storage parts are connected with each other by passages (16a, 16b, 16c, 26). The storage part (12d) is made to hold a buffer solution containing molecules of protein or the like to be crystallized. The storage parts (12a, 12b, 12c) are also made to hold solutions capable of accelerating crystallization of protein or the like respectively. These solutions are shifted to the solution storage part (14) through the passages (l6a, 16b, l6c, 26) for preparing a mixed solution in a different ratio in each storage part (14). Thus, different conditions for crystallization can be simultaneously formed in a short time with a small amount of sample. A crystal of protein or the like is grown in the storage part (14) holding the mixed solution. Growth of the crystal is controlled by the electric properties which are brought to the silicon substrate surface by the valence electron control.
Patent CA-2261295-A1 (CA)
Inventor: ATHANASSIOU CHARALAMBOS N
IPC: A61B6/03
Filed: 1997-07-29
Abstract: A patient is automatically accurately positioned relative to a fixed reference of a treatment/diagnostic device by an optical system which operates a patient positioning assembly to bring fiducials or skin markers on the patient into coincidence with impigement points of laser beams projected in a fixed pattern relative to the device. Cameras record images of the fiducials and laser impingement points from which alignment error and velocity error in pixel space are determined. The velocity error in pixel space is converted to a velocity error in room space by the inverse of an Image Jacobian. The Image Jacobian is initially derived using rough values for system parameters and is continuously updated and refined using the calculated errors in pixel space derived from the camera images and errors in room space derived from position encoders on the treatment/diagnostic device.

Abstract: The disclosed system and method provide a customer with the ability to obtain temporary caller identification services in an Advanced Intelligent Network. The customer initiates the service by dialing a call to a feature access code and does not require the intervention of a service representative. The call by the customer is recognized as a request for.caller identification service. On the basis of the recognition, an association is retained between the line number and the Service Switching Point serving the line number. This retained association may be used later in the activation of the temporary caller identification service for the requested line number. The call is routed to a rental service interface through which rental information from the caller may be collected. This rental information may be compiled into a rental agreement that is used as the basis for activation of the temporary caller identification services with respect to the requested line number. Optionally, confirmation of the activation of caller identification service is provided to the customer during the communication.

Inventor: BINDUGA GARY E
IPC: A42B3/14
Filed: 1998-04-06
Abstract: The present invention provides an adjustable headband for protective headgear with a ratchet mechanism having different resistances.  The adjustable headband utilizes a ring gear assembly (300) having a plurality of radially projecting teeth (325) thereon. Each of the projecting teeth (325) of the ring gear assembly (300) has a first tooth side and a second tooth side which is different from the first tooth side. For example, each tooth of the ring gear assembly preferably has a first tooth angle on the first tooth side and a second, different tooth angle on a second tooth side. A spring assembly (150) having at least one spring tooth (155) projecting radially therefrom is connected to the adjustment knob (100). The spring assembly (150) is positioned such that the at least one spring tooth (155) meshes with the teeth (325) of the ring gear assembly (300) to provide resistance to the rotation of the adjustment knob (100). Because the first tooth angle of the ring gear assembly (300) is different from and preferably less than the second tooth angle of the ring gear assembly (300), it is substantially easier to rotate the adjustment knob (100) in the direction of tightening the headband than in the direction of loosening the headband.

Patent CA-2300244-A1 (CA)
Inventor: WARD KENNETH A
IPC: H04L12/56
Filed: 2000-03-08
Abstract: In a switched configuration in which data links can be bundled to increase data throughput, the links in a bundle are ordered. A data sender sequentially transmits cells in the data packet over links in the bundle. For example, a first cell is transmitted over a first ordered link in the bundle. The next cell is transmitted over the next link in the bundle order and operation continues in a "round robin" fashion. The data receiver is informed in advance of the order of links in the bundle and expects cells to be distributed over the links in that order. The data sender transmits a bundle sequence number with each data cell. As each new data cell is transmitted, the bundle sequence number is incremented. The receiver uses the bundle sequence number to validate cell order, to detect lost cells, and to resynchronize cell order with the sender in the case of cell errors. Bundle sequence numbers are used on a single bundle on a single link, or "hop", between a data sender and a data receiver. When the cells are received by the data receiver of a hop, the received bundle sequence numbers are replaced by new bundle sequence numbers generated by the data sender for transmission over the next hop.
