Title: Adjuvant for transcutaneous immunization
Inventor: GLENN GREGORY M
IPC: A61K9/70
Filed: 1997-11-14
Granted: 2003-07-29
Abstract: A transcutaneous immunization system delivers antigen to immune cells withou t perforation of the skin, and induces an immune response in an animal or huma n. The system uses an adjuvant, preferably an ADP-ribosylating exotoxin, to induce an antigen-specific immune response (e.g., humoral and/or cellular effectors) after transcutaneous application of a formulation containing antigen and adjuvant to intact skin of the animal or human. The efficiency o f immunization may be enhanced by adding hydrating agents (e.g., liposomes), penetration enhancers, or occlusive dressings to the transcutaneous delivery  system. This system may allow activation of Langerhans cells in the skin, migration of the Langerhans cells to lymph nodes, and antigen presentation.< /SDOAB>

Abstract: A low power management system including both hardware and software is provided for a battery powered portable computer (not shown). The low power management system powers down various sections of the computer (DMA, VCO, DISPLAY, UART) when they are not used. The low power management system is controlled by a control program directing the microprocessor of the computer, and includes the capability to turn off clock signals (not shown) to the various sections of the computer based upon demand. Also included is the capability to turn on clock signals based upon demand. The low power management system also includes the capability to turn on the computer upon a press of a key on the computer keyboard. The low power management system monitors software application programs for keyboard activity so as to turn off the microprocessor in the computer in response to a loop looking for a keypress and certain other loops which can be monitored without use of the microprocessor.
Patent CA-2289367-C (CA)
Inventor: SHESHTAWY ADEL
IPC: E21B17/10

Granted: 2003-09-16
Abstract: A tool for expanding a hole size while drilling tool is disclosed. The tool utilizes a mechanically actuated mandrel and extendable cutting lugs designed in a configuration with fewer moving parts than previous designs. The cutting lugs have multiple cutting elements attached. The cutting lugs are driven between two cylindrical diameter surfaces to achieve a large differential between the retracted and extended positions of the tool, and to provide sufficient stability to allow the tool to be used in the extended position while drilling forward. The lugs are internally assembled and tapered to closely match the slots in the body of the tool for additional stability and to prevent complete passage through the tool for prevention of catastrophic failure. The tool has a locking mechanism to allow the tool to remain in the extended position when the weight is removed from the tool. In an alternate embodiment, the cutting lugs may be replaced with stabilizing lugs having a wear resistant surface or mounted with wear resistance elements to form an expanding drill string stabilizer.

Title: Use of lysophosphatidylethanolamine (18:1) and lysophosphatidylinositol to retard senescence and to enhance fruit ripening
Inventor: RYU STEPHEN BEUNGTAE
IPC: A23L3/3526
Filed: 1998-11-09
Granted: 2007-08-21
Abstract: The present invention relates to a method of enhancing fruit ripening and stability and of delaying senescence in fruit and other plant tissues. This method consists of applying an effective amount of a lysophospholipid, such as lysophosphatidylethanolamine (18:1) (hereinafter referred to as "GPE (18:1)") or lysophosphatidylinositol (hereinafter referred to as "LPI") to the fruit and other plant tissues.  Lysophospholipids such as LPE (18:1) and LPI were found to be superior to other lysophospholipids in delaying senescence and in inhibiting phospholipase D, a key enzyme in mediating membrane deterioration during of plant senescence. LPE (18:1) and LPI are naturally occurring and environmentally safe. Their use could replace many environmentally toxic compounds that are currently being used to retard senescence of flowers, fruits and leaves and to enhance fruit ripening.

Abstract: A laser delivery system and method incorporate a diffractive optic beam integrator. The diffractive optic apparatus for modifying the spatial intensity distribution of an excimer laser beam (10) to generate a spatially integrated beam comprises a diffractive optic diffuser (12) and a converging lens (22). The diffractive optic diffuser (12) includes a diffractive grating pattern etched in a transparent medium for transforming the intensity profile of the excimer laser beam into a generally circular, substantially uniform spatial intensity distribution at a spatial integration plane. A variable aperture positioned about the spatial integration plane selectively passes the spatially integrated beam to an imaging lens. The imaging lens forms an image of the passed beam about a surface of a tissue to be ablated. A scanning element under computer control scans the imaged beam about the surface.

Abstract: A recessed downlight wall wash reflector assembly and method of installing the same. The reflector assembly is installable from below the plane of a ceiling into a standard mounting frame for a recessed downlight reflector having a similarly sized light exit aperture. In the preferred embodiment configured for use as a single wall washer, the reflector assembly has a downlight reflector, a window cutout in the wall of the downlight reflector and a resilient wall wash reflector attached to the reflector assembly such that it is positioned behind the window cutout. The resilient wall wash reflector has flexible sides which flex inward, allowing the reflector assembly to fit through the mounting frame opening during installation. Once the assembly has cleared the frame opening, the flexible sides return to their original shape. In an embodiment preferred for use as a corner or double (parallel) wall washer, the reflector assembly has a yoke assembly having a top plate and a leg extending between the top plate and the mounting frame. The yoke assembly may be installed through the mounting frame opening and secured to the mounting frame from below the ceiling. Wall wash reflectors may then be installed through the opening and attached to the yoke assembly. Lastly, a downlight reflector with window cutouts may be installed through the opening and attached to the yoke assembly such that the window cutouts are positioned in front of the wall wash reflectors.

Granted: 2007-04-17
Abstract: A breaking system is able to meet emergency stopping distance requirements associated with a failed rear axle service control line (40) by modifying the service relay valve (26). The service rel ay valve incorporates a biased double check valve (100) so that an additional or secondary control line (50) from the foot control valve (20) communicates with the service port of the relay valve.

Granted: 2009-11-17
Abstract: L'invention concerne un procédé de préparation de corps cristallins contenant de l'argile, du magnésium, du silicium et de l'aluminium, à partir de sources aluminium, magnésium et silicium. Ce procédé comporte les étapes suivantes : a) préparation d'un mélange précurseur b) mise en forme de ce mélange précurseur en vue d'obtenir des corps façonnés; c) éventuellement traiter thermiquement ces corps façonnés et d) vieillissement en vue d'obtenir des corps cristallins contenant de l'argile, du magnésium, du silicium et de l'aluminium. Le plus grand intérêt de la présente invention réside dans le fait que les corps sont façonnés avant la formation de l'argile cristalline dans lesdits corps. Ceci permet de produire des corps très résistants à l'usure, sans adjonction nécessaire de matériau de liaison. L'argile cristalline est produite à partir des sources aluminium, magnésium et silicium. En cas d'absence de source silicium, on obtiendrait alors de l'hydrotalcite. Si on réunit des sources aluminium, magnésium et silicium, on obtient alors de la saponite ou de la montmorillonite.
