Abstract: The finished product is a globe, which has been modified/remanufactured to house a light source in the interior of the globe.      The surface of the globe is remanufactured by drilling precise holes in predetermined locations from the outer surface and through to the inner surface of the globe. These holes permit the interior ambient light created (when the interior light source is turned on) to escape or be transmitted out from the interior of the globe. The interior light escapes via the precise point of the hole on the surface of the globe.      The placement of multiple holes on the surface of the globe allows for multiple precise points of light to escape from the interior of the globe.   An example: if the precise points of light escape from the world's major cities (as depicted on the printed surface/map of the globe), the desired effect would be a view of our: (a) Earth's night time surface as may be seen from near space; (b) Earth's night-lights (c) Earth's population depicted with light (d) Earth's city and town light output (e) Earth's electrical output Typically, when the example of a model of earth is produced, approximately 600 light points must be drilled and prepared to achieve the above-mentioned desired effect.      If the modification or remanufacturing process has been successfully completed then the following two visual effects are achieved:                1. During daylight hours or when the interior light source is turned off, the modified globe shows no signs of the light points when viewing the globe from most distances. Only from very close scrutiny: i.e., viewing the globe from within a few inches can one determine that light points have been installed in the globe. 2. Only when the globe's interior light is turned on can one tell that the globe has been modified or remanufactured to show multiple light points on the surface of the globe.

Abstract: A refrigerator includes a housing that defines an enclosable storage space.  The refrigerator includes a closed manifold which defines a chamber to contain refrigerant. The chamber is made up of three parts, a cooling pipe, a head pipe, and one or more heat pipes to communicate fluid between the cooling and head pipes. The heat pipes are flat, elongated, and are divided internally to form capillary channels to permit flow of refrigerant between the cooling and head pipes. An array of thermoelectric modules contacts a surface of the manifold to chill refrigerant within the manifold. A pump or compressor is not required to circulate the refrigerant within the system. A blower forces an air stream to cool the heating faces of the thermoelectric modules. A control unit may be used to maintain the operating temperature of the refrigerator. A refrigerator may be portable, with a portable power source or adapters. The manifold design is useful for modular refrigerator appliance designs. The manifold is also useful in other refrigerating systems, cold storage units and portable devices.

Abstract: A mukti-functional fastener driver device l0 that is capable of providing rotational force to fasteners having different configurations (hexagonal, flathead, wingnut or hook screw, for example) to urge a preselected fastener into a workpiece. The device 10 includes a first portion 12 that is secured, via a shank portion 16, to a tool providing rotary force, and a second portion 14 that transfers the rotary force to a preselected fastener via a plurality of arm members 30. The arm members 30 are configured from multiple apertures 24 and 38, and slots 32 and 34. The arm members 30 engage the fastener and force the fastener to rotate thereby "screwing" the fastener into the workpiece. When fasteners are to large to rotate without deforming the arm members 30, a sleeve 42 is utilized to snugly receive the device 10 therein to maintain the arm members 30 configuration while rotating the fastener. Further, the sleeve 42 includes opposing recesses 52 in an end wall 50. The recesses 52 are adapted to align with a slot 32 or 34 in a fastener receiving end 25 of the device 10 to allow the drive ends of large fasteners to be engaged by both the device 10 and the sleeve 42.

Inventor: LUO YAN
IPC: C12N15/09
Filed: 2001-03-02
Abstract: The subject invention relates to antisense oligonucleotides of the human Chk1 gene and to uses thereof. The human ChK1 gene is a major G2/M checkpoint gene that is activated in response to DNA damage. In particular, the gene transduces the inhibitory signal from DNA damage sensors to the basic cell cycle machinery. Thus, antisense oligonucleotides to the human Chk1 gene may be used, for example, to inhibit the gene thereby preventing G2 arrest induced by DNA damaging agents. Such antisense oligonucleotides should also further sensitize tumor cells thereby making them more sensitive to therapy than normal cells.

Abstract: A description is given of a method as well as a plant for manufacturing cement clinker by which method cement raw meal is preheated in a preheater (1), calcined in a calciner (3) comprising an upper end (3a) and a lower end (3b), burned into clinker in a kiln (5) and cooled in a subsequent clinker cooler (7). The invention is peculiar in that exhaust gases from the kiln (5) are introduced into the upper end (3a) of the calciner, in that fuel is likewise introduced into the upper end (3a) of the calciner, in that the exhaust gas/fuel suspension is directed down through the calciner (3), in that preheated air from the clinker cooler (7) and preheated raw meal from the preheater (1) in combination or separately are fed into the calciner (3) at a location under the zone where exhaust gases from the kiln and fuel are introduced, in that the preheated air is directed down through the caliciner (3), being gradually mixed with the exhaust gas/fuel suspension, in that the raw meal under the action of gravity is directed down through the calciner (3) along its wall, being suspended in the exhaust gases at the lower end (3b) of the calciner, and in that the exhaust gas/raw meal suspension is extracted from the lower end (3b) of the calciner and conveyed to a separating means (4) for separating the raw meal which is subsequently directed to the kiln (5).  Hereby is obtained a significant reduction of the NOx which is led to the calciner together with the kiln exhaust gases, a high degree of fuel burn out even when using fuels with a low content of volatile constituents, and a low degree of conversion into NOx of the nitrogen which is led to the calciner together with the fuel.

Patent CA-2430578-A1 (CA)
Inventor: KONERMANN LARS
IPC: G01J3/00
Filed: 2003-05-30
Abstract: The present invention provides a method and apparatus for detecting the noncovalent binding of a potential ligand (such as a drug candidate) to a target, e.g. a biochemical macromolecule such as a protein. The method is based on the Taylor dispersion of an initially sharp boundary between a carrier solution, and an analyte solution that contains the potential ligand(s) and the target. Dispersion profiles of one or more potential ligands are monitored by mass spectrometry at the exit of the laminar flow tube. Potential ligands will usually be relatively small molecules that have large diffusion coefficients. In the absence of any noncovalent interactions in solution, very steep dispersion profiles are expected for these potential ligands. However, a ligand that binds to a large target in solution, will show an apparent diffusion coefficient that is significantly reduced, thus resulting in a more extended dispersion profile. Noncovalent binding can therefore be detected by monitoring dispersion profiles of potential ligands in the presence and in the absence of the target. In contrast to other mass spectrometry-based methods for detecting noncovalent interactions, this method does not rely on the preservation of specific noncovalent interactions in the gas phase. This method has an excellent sensitivity and selectivity, therefore it can be used for testing multiple potential ligands simultaneously. The method is therefore useful for the high throughput screening of compound libraries.
