摘要:
The present invention relates to a self-contained device to maintain a specific level of liquid in a pool, spa or other small body of water. More specifically, the invention relates to a self-contained mechanical device that can be detachably mounted to a spa at a desired level and maintain the level of liquid in that spa using a floatation device connected to a stopper via a lever arm. As liquid enters the device chamber through a liquid intake opening, the flotation device rises along with the level of liquid in the device. A liquid outlet opening allows the liquid in the device to exit into the spa to be maintained, thereby equalizing the level of liquid in the device and the spa. When the liquid rises to a desired level, the flotation device rises as well, pulling the lever arm and closing the stopper over the liquid intake opening.

Melanin concentrating hormone receptor ligands (especially 1-benzyl-4-aryl-piperazines, 1-benzyl-4-aryl-piperidines and related compounds), capable of modulating MCH receptor activity, are provided. Such ligands may be used to modulate MCH binding to MCH receptors in vivo or in vitro, and are particularly useful in the treatment of a variety of metabolic, feeding and sexual disorders in humans, domesticated companion animals and livestock animals. Pharmaceutical compositions and methods for treating such disorders are provided, as are methods for using such ligands for detecting MCH receptors (e.g., receptor localization studies).

Cermets are provided in which a substantially stoichiometric metal carbide ceramic phase along with a reprecipitated metal carbide phase, represented by the formula MxCy, is dispersed in a metal binder phase. In MxCy M is Cr, Fe, Ni, Co, Si, Ti, Zr, Hf, V, Nb, Ta, Mo or mixtures thereof, x and y are whole or fractional numerical values with x ranging from 1 to 30 and y from 1 to 6. These cermets are particularly useful in protecting surfaces from erosion and corrosion at high temperatures.

摘要:
The orientation of a camera associated with a first image is determined based on a shape of a perimeter of a corrected version of the first image. The corrected version of the first image has less perspective distortion relative to a reference image than the first image. The shape of the perimeter of the corrected version of the first image is also different from the shape of the perimeter of the first image. The first image is then projected onto a surface based on the orientation of the camera.
摘要:
A method and apparatus for controlling torque delivery independently, i.e., asymmetrically, to the two rear axles and wheels of a vehicle with front wheel drive provides improved vehicle handling and performance. The apparatus includes a prime mover, transaxle, power takeoff, rear axle having a pair of independently controllable modulating clutches driving respective rear axle and wheels, various vehicle sensors and a microprocessor. The method, embodied in software in the microprocessor, senses wheel speeds, yaw rate, lateral acceleration, throttle position and steering wheel angle, determines various reference values and oversteer and understeer conditions and activates one or both of the two clutches.

This invention relates to low molecular weight, non-peptidic, non-peptidomimetic, organic molecules that act as modulators of mammalian complement C5a receptors, preferably ones that act as high affinity C5a receptor ligands and also to such ligands that act as antagonists or inverse agonists of complement C5a receptors, preferably human C5a receptors, Preferred compounds of the invention possess one or more, and preferably two or more, three or more, four or more, or all of the following properties in that they are; 1) multi-aryl in structure (having a plurality of un-fused or fused aryl groups), 2) heteroaryl in structure, 3) orally available in vivo (such that a sub-lethal or preferably a pharmaceutically acceptable oral dose can provide a detectable in vitro effect such as a reduction of C5a-induced neutropenia), 4) comprised of fewer than four, preferably fewer than three, or fewer than two, or no amide bonds, and 5) capable of inhibiting leukocyte chemotaxis at nanomolar concentrations and preferably at sub-nanomolar concentrations. Specifically exemplified representative compounds include, but are not limited to optionally substituted arylimidazoles, optionally substituted arylpyridyls, optionally substituted aryl-substituted cycloalkylimidazoles, optionally substituted arylpyrazoles, optionally substituted benzimidazoles, optionally substituted aryl-substituted tetrahydroisoquinolines, and optionally substituted biaryl carboxamides. This invention also relates to pharmaceutical compositions comprising such compounds. It further relates to the use of such compounds in treating a variety of inflammatory and immune system disorders. Additionally, this invention relates to the use such compounds as probes for the localization of C5a receptors.
