摘要:
A wellhead housing has a casing hanger with an actuator mechanism to provide for direct transfer of casing and pressure loads to the housing even in conditions where the casing hanger may be set in a high position in the wellhead housing on a load shoulder, or in a casing hanger in the wellhead housing for an earlier installed, larger diameter casing string.

Disclosed herein is an aerogenerator having a horizontal maintaining means. The aerogenerator of the present invention includes a support pillar which is placed upright on the ground and has a hollow space therein. The aerogenerator further includes a rotational support unit which is provided on the upper end of the support pillar so as to be rotatable. The rotational support unit includes a rotational body and a rotational support base which supports the lower end of the rotational body. The opposite ends of the rotational support base extend predetermined lengths from the rotational body outwards. The aerogenerator further includes vane units which include a main vane and a subsidiary vane provided on the respective opposite ends of the rotational support base of the rotational support unit. The main vane and the subsidiary vane have different weights. The aerogenerator further includes a generating unit which converts the rotating force of the vane units into electric energy, a rotating force transmission unit which transmits the rotating force of the vane units to the generating unit, and the horizontal maintaining means which connects the vane units to the rotational body to maintain central axes of rotating shafts of the vane units horizontal.
摘要:
A device and a method for creating and/or maintaining an obstruction free upper respiratory passages. The device is configured to fit under the chin of a subject adjacent to the subject's neck at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The device is capable of exerting negative pressure on the surface of a subject's neck, displacing the soft tissue forward and enlarging the airway.

摘要:
The present invention describes methods of using terminal-phosphate-labeled nucleotides in the presence of a manganese salt to enhance their substrate properties towards various enzymes. Particularly described are methods of detecting a nucleic acid in a sample, based on the use of terminal-phosphate-labeled nucleotides as substrates for nucleic acid polymerases, in the presence of a manganese salt. Further provided are manganese complexes of terminal-phosphate-labeled nucleotides as well as terminal-phosphate-labeled nucleotides with new linkers with enhanced substrate properties.

A system for providing anti-islanding protection of a synchronous machine based distributed generator includes a frequency sensor configured to generate a generator frequency signal, a bandpass filter configured for filtering the generator frequency signal, a governor controller configured for using the filtered frequency signal to generate a power feedback signal, and a governor summation element configured for summing the filtered frequency signal, the power feedback signal, and a reference power to provide an electrical torque signal. Another system includes a voltage sensor configured to generate a generator terminal voltage signal, a feedback power calculator configured for generating a reactive feedback power signal, a bandpass filter configured for filtering the terminal voltage signal, and a PI controller summation element configured for summing the filtered terminal voltage signal, the reactive power feedback signal, and a reference reactive power to provide an error signal.
摘要:
Error-testing of merchant messages to be used with point-of-sale (POS) devices is performed by an automated system that receives a formatted message to be tested from a merchant or an agent of the merchant, performs a computer-implemented evaluation of the message according to predefined message-validation rules to detect one or more errors, and notifies the merchant or the agent of evaluation results. The evaluation results include a listing of each detected error, if any.
摘要:
An apparatus and method for manufacturing small quantities of cigarettes in a substantially simultaneous fashion while maintaining consistent quality between the cigarettes. The apparatus provides for arranging loose tobacco into tobacco charges and simultaneously inserting the charges into pre-formed tubular cigarette wrappers.
摘要:
Cigarettes are manufactured using modified automated cigarette making apparatus. Those cigarettes possess smokable rods having paper wrapping materials having additive materials applied thereto as patterns. The additive materials, which can have the forms of liquid or paste formulations, can be applied to the paper web using application apparatus possessing rollers. One of those rollers can have a series of pockets in its roll face to receive additive formulation from a reservoir and to define the pattern of the formulation on the paper. A radiant dryer can be used to dry the additive material that has been applied to the paper web. The radiant dryer can be located on one component of a two component assembly that is used to manufacture cigarettes. Spectrometric techniques can be used to ensure proper registration of the additive material on the cigarette rods so manufactured, and to ensure proper quality of those cigarettes.
