Title: Expandable retaining shoe
Inventor: CROCKFORD LLOYD A
IPC: E21B33/12
Filed: 2002-07-30
Abstract: An improved downhole tool apparatus and method for limiting the extrusion of a packer element. The apparatus includes a mandrel having a packer element assembly. Packer retaining shoes are disposed about the mandrel at the ends of the packer element assembly. The packer retaining shoes have an inner retainer and an outer retainer. The inner retainer has a plurality of segments having gaps therebetween that expand in width when the retaining shoe is moved from the initial position in which it is disposed about the mandrel to an expanded position wherein it engages the casing to limit the extrusion of the packer element assembly. The outer shoe is likewise made up of a plurality of segments having gaps therebetween that will expand. The inner shoe segments cover the gaps that exist between the outer shoe segments and the outer shoe segments cover the gaps that exist between the inner shoe segments so that extrusion is limited. The retaining shoes provide enhanced high temperature and higher pressure performance in that extrusion in wells having high temperature and high pressure is severely limited if not completely prevented.

Title: Plant brassinolide responsive genes and use thereof
Inventor: YANG GUANGXIAO
IPC: C12N15/09
Filed: 2002-11-26
Abstract: The objective of the present invention is to isolate and identify genes responsive to plant hormones, such as, brassinolide, and to provide these genes and their use. The present inventors found two novel genes (referred to as OsBLE1 gene and OsBLE2 gene) whose expressions are markedly increased by brassinolide and auxin, using DNA microarray techniques and Northern blotting. Transformed rice plants were produced using Agrobacterium EHA101 which comprise antisense polynucleotide against OsBLE1 and OsBLE2 under the control of the CaMV35S promoter in a binary vector pIG121-Hm. As a result, the transformed rice plants exhibited inhibition in stem and leaf growth as compared with controls which carried the vector alone.

Title: High temperature cryogenic preservation of biologically active material
Inventor: BLANTON JOHN
IPC: A01G7/00
Filed: 2001-06-12
Abstract: Viable biological material is cryogenically preserved (cryopreservation) by preparing the material for freezing, immersing the material in a tank of cooling fluid, and circulating the cooling fluid past the material at a substantially constant predetermined velocity and temperature to freeze the material. A method according to the present invention freezes the biologic material quickly enough to avoid the formation of ice crystals within cell structures (vitrification). The temperature of the cooling fluid is preferably between -20 ~C and -30 ~C, which is warm enough to minimize the formation of stress fractures in cell membranes due to thermal changes. Cells frozen using a method according to the present invention have been shown to have approximately an 80 percent survival rate, which is significantly higher than other cryopreservation methods.

Title: Solution drying system
Inventor: DICK KENNETH W
IPC: G01N33/483
Filed: 2002-11-27
Abstract: A system for drying chemical reagents on material, particularly for producing product used in making reagent test strips is described. By drying selected chemicals on substrate drawn past a radiant energy source (preferably an IR source), rapid drying may be achieved while obtaining high-quality product. Airflow sufficient to break or disturb a vapor boundary layer above drying solution may be provided to increase drying speeds. Any airflow provided should not disturb the surface of the solution. Still, air-impingement drying techniques may be employed in the system to finish drying reagent material once it is sufficiently dry to be stable in shape. The substrate upon which chemicals are dried may include a reflective coating to facilitate its use with high levels of radiant energy. A metallic or metalized substrate is advantageously used in producing electrochemical test strips. Such test strips may be used in conjunction with various kits and be conveniently read using known hand-held meters.

IPC: G06F17/30

Abstract: When searching for new people, the current instant messaging networks typically allow users to search mainly by name or by e-mail and some of them also by interests, although one of them (Odigo) allows to search also by sex, age, area, languages, occupation &, interest. However, to the best of the inventor's knowledge there is no way to systematically search in these networks for compatible personality, or by reciprocal compatibility in any of the above mentioned attributes. This is a waste of huge potential since some of these networks already have more than dozen of millions of people. Also, Odigo allows searching by only among people currently connected, which means that highly compatible dates can be missed just because they don't happen to be connected at exactly the time of the search. The present invention is a novel concept which applies computer dating to the context of instant messaging, in a systematic and flexible way that to the best of the inventor's knowledge has never been done before. This system and method enable the user to search and instantly compatible dates in instant messaging networks on the basis of attribute search or 1-way compatibility search or 2-way compatibility search instead of being limited to search only by the limited options described above, and to search either for potential dates that are currently Online or Offline, and also take advantage of many additional features, and especially features that are based on improved integration between computer dating and instant messaging.

Filed: 2003-07-25
Abstract: A manipulative toy is provided comprising a body and a plurality of interchangeable appendages, such as arms, legs, heads, tails and wings, said appendages being removably attachable to the body at certain predefined coupling points by means of complementary magnetic elements disposed within both said appendages and said body. Said appendages are retained in place by means of the interaction between two sets of complementary ribbed elements disposed on both the body and the appendages about said magnetic elements, which complementary ribbed elements are formed in a beveled configuration. The configuration of these ribbed elements, in combination with attractive force of the complementary magnetic elements and the frictional engagement of the complementary ribs, limits the appendages from moving rotationally about the point of attachment, and limits the movement of the appendage in the plane of the point of attachment, thereby allowing the manipulative toy to be posed by a user and retain its position.

Title: Methods of introducing treating fluids into subterranean producing zones
Inventor: BRADLEY TODD L
IPC: C09K8/528
Filed: 2003-09-25
Abstract: Methods of uniformly introducing aqueous treating fluids into subterranean producing zones are provided. The methods are basically comprised of the steps of packing perforation tunnels in the producing zone with a particulate solid anhydrous borate material which degrades and dissolves in water over time. A treating fluid is then introduced into the subterranean zone by way of the packed perforation tunnels whereby the treating fluid uniformly flows into the producing zone. The particulate solid anhydrous borate material in the perforation tunnels is allowed to degrade and dissolve in an aqueous fluid in contact therewith so that the aqueous fluid and produced formation fluids freely flow into the well bore.

Title: Workpiece forming
Inventor: WAY JEROME
IPC: B21D26/055
Filed: 2002-08-07
Abstract: A method of forming a workpiece (18) comprises: holding the workpiece adjace nt a mould (20); using a laser (30) to heat at least a part of the workpiece to a temperature sufficient to induce superplasticity; and applying a fluid pressure to the workpiece, so that it takes the shape of the mould. This has the advantage that the superplastic properties of the material can be used t o form the workpiece precisely to the required shape, without needing to heat all of the processing chamber to the superplastic temperature. Before using the laser to heat the workpiece to its superplastic temperature, the laser c an be used to heat the whole of the workpiece to a substantially uniform temperature to anneal it. Similarly, after using the laser to superplastical ly form the workpiece, the laser is used to heat the whole of the workpiece to a substantially uniform temperature to remove any residual stresses. This has the advantage that the whole of the forming can be carried out as a single process, in a single processing apparatus.
