Patent CA-2462300-C (CA)

Abstract: A hierarchy may be explicitly or implicitly reflected in existing data maintained external to hierarchy structures. Such hierarchies are referred to herein as a "pre-existing hierarchies". Techniques are described herein for capturing a pre-existing hierarchy in hierarchy structures. After a pre-existing hierarchy has been captured, there exist two independent sets of data that reflect the hierarchy: the external hierarchy definition and the internal hierarchy definition. Changing either hierarchy definition changes the hierarchy. Therefore, to maintain a consistent reflection of the hierarchy, the internal hierarchy definition must be modified in response to changes made to the external hierarchy definition, and the external hierarchy definition must be modified in response to changes made to the internal hierarchy definition. Various techniques are described for maintaining consistency between the two hierarchy definitions.

Title: Modular in-wall medical services outlet system
Inventor: WALKER JAMES A
IPC: E04H1/00
Filed: 2004-05-14
Granted: 2011-07-19
Abstract: A modular in-wall medical services outlet system comprising separate standardized vertical units that can be shipped separately and assembled on site to form a consolidated horizontal system. The system includes a self-aligning feature that allows the units to be leveled as a single whole and eliminates the need to level each unit separately. The alignment system may be combined with connectors which secure the units to each other. Racks of medical service outlets are included. The racks may be horizontally aligned, vertically aligned, or both. Substantially continuous trim and cover plate assemblies extend entirely across the face of the system around the outlets giving the system the appearance of an in-wall horizontal unit. The trim is attachable to the wall structure, receives the wall board, supports the service outlets, and provides horizontal equipment tracks. The frame provides the system with load bearing capacity to support equipment in the horizontal tracks.

Abstract: An enzyme having an activity of transferring N-acetylglucosamine to an N-acetylgalactosaminyl group via a .beta.-1,3 bond; a nucleic acid encoding the same; and a method of diagnosing cancer and/or tumor, in particular, cancer and/or tumor in digestive organs using the expression dose of the gene of the above enzyme as an indication. A novel gene of an enzyme having an activity of transferring N-acetylglucosamine to an N-acetylgalactosaminyl group via a .beta.-1,3 bond is cloned from human intestinal and gastric cells and its base sequence is determined. Then this enzyme is expressed and, moreover, a monoclonal antibody against this enzyme is constructed. Since this enzyme is not or little produced in cancer and/or tumor cells, in particular, cancer and/or tumor cells in digestive organs, cancer and/or tumor can be diagnosed using the expression dose of the gene of the above enzyme as an indication.

Granted: 2012-06-05
Abstract: The invention concerns a method for making thin-film CIGS which consists in: electrochemically depositing on a substrate a layer of stoichiometry close to CuInSe¿2?; then rapidly annealing said layer from a light source with pulses of sufficient power to recrystallize CIS. Advantageously, the electrodeposited elements are premixed. Thus, after the deposition step, a homogeneous matrix is obtained which can support sudden temperature increases during the rapid annealing.

Abstract: The present invention generally provides apparatus and methods for reducing the pressure of a circulating fluid in a wellbore. In one aspect of the invention an ECD (equivalent circulation density) reduction tool provides a means for drilling extended reach deep (ERD) wells with heavyweight drilling fluids by minimizing the effect of friction head on bottomhole pressure so that circulating density of the fluid is close to its actual density. With an ECD reduction tool located in the upper section of the well, the friction head is substantially reduced, which substantially reduces chances of fracturing a formation.

Abstract: The method is referred to hydrometallurgy process and it serves for recovery of nonferrous, rare and precious metals from robust (hard to process) minerals, which may contain natural carbon or other robust compounds. This invention is aimed at increasing the recovery of nonferrous, rare and precious metals from robust minerals with simultaneous reduction of processing costs. The objective is attained, as the method for recovery of nonferrous, rare and precious metals from robust minerals envisages the processing of robust carbon- containing minerals by oxygen-containing oxidant with subsequent extraction of precious metal compounds from liquid phase, moreover, the treatment of robust carbon-containing minerals by oxygen-containing oxidant is performed in the presence of reducing agents featuring donor-acceptor properties, which are manifested in the fact that at the first stage of chemical reactions the reducing agents give their electrons to oxygen-containing oxidant and, as a result, form a stronger oxidant than the initial one, in the from of short- lived radicals and intermediate oxidation products of donor-acceptor reducing agents, which are oxidants, as well.

Abstract: In a rising gathered member 4 of an absorbent main body 3 attached to an external sheet 2, an inward folded base end 4b is joined astride a side end 13a of a top sheet 13 as a top surface of the absorbent main body 3 and a side end 14a of a back sheet 14 so that the rising gathered member 4 rises from a most side edge 3a in a width direction of the absorbent main body 3 and, also, the back sheet 14 of the absorbent main body 3 is attached onto a skin-contacting surface side of a crotch part R of a second external sheet 8 at an inward position at a prescribed width W5 from the most side edge 3a of the absorbent main body 3 as an outermost joint position. With the above constitution, it is possible to effectively prevent any lateral leakage of urine and the like, even if a disposable absorbent article is shifted.  Moreover, the base end of the rising gathered member is merely joined to the side end of the top surface of the absorbent main body, thereby requiring no sheet winding step or the like, such a simple process can achieve inexpensive production, and further, the stability of product precision becomes improved.

Granted: 2011-03-29
Abstract: A subscriber profile access management system for a telecommunications service provider or telecommunications operator provides technical solutions to providing a single point of access to telecommunications subscriber profile information. As the products and services offered by the service provider grow, and given the many different access mechanisms through which a subscriber connects to services, the single point of access eliminates the inefficient proliferation of custom interfaces between the many support systems and applications which need access to subscriber profile information. The single point of access provides a universal and personalized access to telecommunications services. Access may be made to the subscriber profile regardless of the particular type of access mechanism (e.g., WiFi, or DSL access), while the personalized access allows services to be customized based upon static and dynamically maintained information in the subscriber profile.
