Title: Innovative inclined plane earth engaging tool
Inventor: WATTS CLEAL T
IPC: E02F9/28
Filed: 2000-02-07
Abstract: The Inclined plane (22) is a earth engaging tool arranged and constructed to be used as one or several in a set of inclined planes (22). A structural implement (28) replacing the sharp pointed lip (Fig 3) and teeth (30) arranged with one or a set of inclined planes (22) can be constructed and arranged for optimum encounter of earth excavation to fracture, cleave, and uplift earth usually, but not always, in unison.   An expected application would be found on a dragline, shovel, a loader type bucket, or other earth engaging implement.   It is a robust, one piece, ascending, rectangular, durable metal slope, arranged at approximately 50 degrees of encounter. Its thickness is 5% to 10%, of its length and its width almost half its length.     Its leading edge (20, of Fig 5,6,8,and 9) and approximately the first one third of the inclined plane (22), is optionally constructed for optimum earth engagement. Some optional arrangements include, leading edge pointed (20a) leading edge narrowed (20b), and a wear edge (27) added to the leading edge (20) of inclined plane (22). This thickened edge is for use in consolidated and abrasive earth.  Its leading edge (20) initiates the fracturing and cleaving and is also constructed and arranged for optimum encounter of earth excavation.   The final approximate two thirds of inclined plane (22), up lifts excavated earth above and beyond its attachment to an implement (28). This arrangement offers stabilizing forces, especially those, which happen during maximum effort. To help compensate the bending forces of the forward overhang attached at an approximate midsection support, the incline plane (22) has an optional attached rearward overlapping contact to the implement. The approximately midsection support is shown attached to the implement (28) by a mounting socket (32, Fig 2,7, and 8) or by a fastener (23, Fig 5,6, and 9) system incorporating a thrust block (25).     An accompanying clean up edge (24), is approximately half the length of inclined plane (22), and one is located on each side of inclined plane (22, Fig 5 and 6). Clean up edges (24) fill the gaps between the inclined planes (22). They are constructed to attach to the implement (28) with their upper extremities approximately the same height as the inclined plane (22). Clean up edges (24) attach integral to the inclined plane, or they may simply adjoin attached only to the implement (28).   Working more than one inclined plane (22) in unison and arranged to bridge cleave, results in little to no abrasion to the implement (28), superior excavation performance, and excellent staying.   This Innovative Inclined Plane Earth Engaging Tool can require considerable less energy or horse power to perform the same task.

Title: Spring clamp assembly for thermal stacked components
Inventor: COOK RANDOLPH H
IPC: H05K7/20
Filed: 1997-09-04
Abstract: A spring clamp device (14) providing a compressive stress to a stack of components includes a spring member (28) and a bracket (26) having attachment structure for engaging mating structure near the bottom of the stack. The bracket (26) is first engaged with the mating structure such that is straddles the stack. The spring member (28) is then latched to the bracket (26) under tension in an assembled configuration, thereby applying an upward reaction on the mating structure with the attachment structure of the bracket (26) and applying a downward reaction force to the top of the stack with the spring member (28). The oppositely directed forces apply a compressive stress to the stack, which improves thermal contact between the components.

Patent CA-2304987-A1 (CA)
Title: Inhibition of an fgf-binding protein using ribozymes
Inventor: WELLSTEIN ANTON
IPC: C12N15/09
Filed: 1998-09-25
Abstract: Increased expression of a secreted FGF-binding protein (FGF-BP) occurs in certain autoimmune and malignant disease conditions. It is found, for example, that tumor secretions of FGF-BP results in mobilization and activation of locally-stored FGFs that can serve as an angiogenic switch molecule. Furthermore, it has been found that in an animal model of multiple sclerosis (MS), the exacerbation of the disease is accompanied by increased FGF-BP. Using ribozymes, it is possible to cause cleavage of the FGF-BP mRNA. Hence, administration of ribozymes which cleave the FGF-BP mRNA in sufficient amounts to inhibit disease processes triggered by FGF-BP is appropriate.

Title: Dextran reduced in boron content, process for producing the same, and dextran packed in container in solution state
Inventor: KATO SHIGEAKI
IPC: A61K31/721
Filed: 1998-10-07
Abstract: The present invention relates to dextran whose boron content is reduced to a value less than 0.30 µg/g (dry basis) calculated on the basis of boron atom, a process for producing the same, and dextran with which a container is filled in a solution state.      Dextran of the present invention is obtained by treating a boron-containing dextran with a lower alcohol, and said dextran has such a characteristic that deposition is inhibited or the deposition rate is drastically reduced when using it in the form of a solution. Therefore, an isotonic sodium chloride solution of said dextran is suitably used as substitute plasma or external perfusate in an operation.

Title: Multi-channel grating interference alignment sensor
Inventor: STANTON STUART T
IPC: H01L21/027
Filed: 2000-07-24
Abstract: An alignment sensor having a fixed reference grating and a movable wafer grating receiving electromagnetic radiation from a coherent illumination source. The illumination source is split into two beams by a beamsplitter. One beam is directed to a fixed reference grating and the diffracted orders are collected. The other beam from the beamsplitter is directed to a movable wafer grating. The diffracted orders from the movable wafer grating are collected and caused to interfere with the diffracted orders from the fixed reference grating, causing a phase shift indicative of the wafer movement or misalignment with respect to the fixed reference grating. Multiple channels having discrete wavelengths or colors are used to optimize detection and alignment irrespective of wafer processing variables. A polarization fixture on the illumination source and a central polarizing portion on the beamsplitter is used to provide contrast optimization, or alternately a latent image metrology mode. The alignment sensor improves alignment accuracy irrespective of processing variables and provides flexibility improving efficiency in the manufacture of semiconductor devices.
