摘要:
The present invention relates to a method and device for playing a game in which values of a game piece are gradually revealed. In one embodiment, a housing receives a game piece. The housing includes an opaque portion covering markings on the game piece. The opaque portion is movable for gradually revealing at least one marking on the game piece. The opaque portion can include a pair of movable doors. The doors are moved laterally toward one another to reveal markings on outer columns of the game piece. The doors are moved vertically for revealing markings on an inner column of the game piece.

The production of a purified extracellular bacterial signal called autoinducer-2 is regulated by changes in environmental conditions associated with a shift from a free-living existence to a colonizing or pathogenic existence in a host organism. Autoinducer-2 stimulates LuxQ luminescence genes, and is believed also to stimulate a variety of pathogenesis related genes in the bacterial species that produce it. A new class of bacterial genes is involved in the biosynthesis of autoinducer-2.
摘要:
Mixed carbocycle derivatives containing at least two carbocycles per molecule from the group of anthracenes, adamantanes and steroids with functionalized carbon chains are synthesized and used as modifiers of resist properties and especially etch resistance enhancement and absorption characteristics. These derivatives are characterized by formulas I-V, where A and R may be an anthryl- and/or an adamantyl- and/or a steroid moiety. Methods for the preparation of the above compounds are disclosed.

The present invention provides a method and apparatus for making atomic clocks or atomic magnetometers as self-modulated laser systems based on the physics of push-pull optical pumping. An atomic vapor cell is required to be in the laser cavity. With proper conditions, spontaneous push-pull optical pumping can occur inside the laser cavity. This causes the laser beam to be modulated at hyperfine-resonance frequency. With a fast photodetector, the modulated laser signal can be converted into the electrical signal, which serves as the atomic clock ticking signal or magnetometer signal. The self-modulated laser system does not use any local oscillator and the microwave circuit to lock the oscillator frequency to the hyperfine-resonance frequency, and therefore can consume less power and become more compact than conventional systems. This invention will benefit applications of time measurements and magnetic-field measurements.

A method for the production of acrylic acid of high concentration by absorbing acrylic acid with high absorption ratio of acrylic acid is provided. In a method for producing acrylic acid by a procedure comprising a step of catalytic gas phase oxidation reaction and a step of absorbing the acrylic acid-containing gas, while a low boiling substance-containing solution is introduced into the absorption column via a portion different from the top of the column.

This invention relates to cosmetic applications for topical applications to the human skin. In particular, it relates to anhydrous cosmetic and dermatological compositions, with the capacity for self-warming or self-heating upon application. The self-warming or self-heating cosmetic compositions of the present invention comprise: (i) from about 0.1 to about 99% by weight of an anhydrous skin care preparation; and (ii) from about 0.01 to about 99% by weight of a heating agent selected from polyvinyl amine, polyalkyleneamine or polyalkyleneimine.
摘要:
Bird feeding apparatus comprising a main body that provides access to bird food and a base member having a plurality of shedding faces which are inclined so that a bed of food particles in the main body settling under gravity is shed towards feeding ports located proximal the periphery of the base; where each shedding face has at least two mutually inclined substantially flat surfaces that together form a valley the floor of which descends as it approaches the periphery of the base.
摘要:
A method and system for communicating data inspecting, monitoring and analysis information by signaling between digital devices is described. A process analyzes the data, which is then subjected to a variety of inspection and validation methods and systems. The results created by the process are then used to signal a grade and rating of the data to specified recipients. Additionally, selected reporting and notification are also sent to specified recipients. Dynamic control of the process is provided if specific information is also received for the information to be processed.
摘要:
A method is disclosed which produces acrylic acid in a high yield as maintaining the conditions for purifying acrylic acid in constant ranges and preventing the acrylic acid from polymerization. By using single a single reactor, propylene concentration adjusting in the range of 7–15 vol. % and water concentration adjusting in the range of 0–10 vol. % are introduced thereinto thereby obtaining an acrylic acid-containing gas. Then the gas is introduced to an acrylic acid absorption column to adjust water concentration in the range of 1–45 wt. %, thereby preventing from polymerization.
