摘要:
An audio signal distortion detection device for simplifying the detection of harmonic distortion to aid in setting an amplifier's gain control to match an audio source unit's output voltage. The audio signal distortion detection device generally includes a housing having a plurality of status indicators thereon for indicating the status of an audio signal being fed into the housing's audio input. By utilizing a scaling circuit and processing unit, the present invention may be configured to detect four audio frequencies and compare DC levels of the frequencies to each other to determine if harmonic distortion is present. A distortion illuminator will illuminate when such distortion is detected and thus significantly reduce the effort required to setting an amplifier's gain control.

The present invention discloses a reactor (100) for manufacturing carbon black, said reactor (100) comprising flow guide means (110) provided between a fuel burner (106) and an air inlet (108) for altering the flow path of combustion air entering at the air inlet (108) to result in a better mixing between the fuel and the combustion air, thereby, producing higher temperature hot combustion gases which are subsequently received in a reaction chamber (104) where they react with a carbonaceous feedstock to produce carbon black. The reactor (100) of the present invention increases the carbon black production by 5-20%. Further, the positioning of the flow guide means (110) stabilizes the flame from the fuel burner (106) to maintain it along the reactor axis, thus, increasing the life of the refractory lining (114).

Disclosed herein is a method comprising: (a) adding an aqueous solution comprising a quaternary ammonium salt to an organic solvent in a vessel under an inert atmosphere, thereby forming a first mixture comprising the quaternary ammonium salt and the solvent; and (b) mixing the first mixture at a temperature and for a time sufficient to remove water and a portion of the solvent from the first mixture, wherein the mixing is performed in an inert atmosphere and the temperature is less than the decomposition temperature of the quaternary ammonium salt.
摘要:
Under the present invention source code can be shared among nodes in a peer-to-peer network. Specifically, source code to be shared will first be analyzed to identify a set of code patterns, assigned one or more predetermined categories based on the set of code patterns, and then selectively indexed. A developer desiring to use previously created source code when creating a new program can perform a context dependent search based on his/her working code to identify and retrieve relevant source code.
摘要:
A process for preparing 1,7′-dimethyl-2′-propyl-2,5′-bi-1H-benzimidazole of formula (I) reacting N-methyl-o-phenylenediamine of formula (II) or the salts thereof with 2-propyl-4-methyl-1H-benzimidazole-6-carboxylic acid of formula (III) or the salts thereof wherein the coupling and cyclization is achieved using 1,3,5-triazine and tertiary amine.
摘要:
A hanger organizer is provided for supporting and organizing a plurality of articles in a hanging position. The apparatus includes a mechanism that enable multiple items to be hang in an efficient manner and easily be removed from the device. The apparatus includes a hanging element, a connector body, and a ring assembly connected to the hanging element is connected to the top side and the bottom side has a support. The ring assembly moves around the support and can be opened or closed. A biasing element located between the ring main body and a closable element keeps the ring assembly closed until items are hung on the ring assembly.
摘要:
A training bat has a central rod extending through the longitudinal length of the bat. A knob may be located at a proximal end of the bat. A handle located immediately distal to the knob may slide along the length of the rod. A cone section may be located distal to the handle. The knob and cone section may limit the longitudinal sliding of the handle. A barrel section may be located distal to the cone section. If the barrel section includes an interior chamber, the distal end of the barrel section may include a removable cap. Weights, springs, pins and other objects may be located inside the barrel section. Electrical components or other devices may also be included in the cone section, barrel section or cap. The handle may include an acoustic chamber and an amplifying chamber to provide for emission of a sound when the bat is swung. The acoustic chamber and amplifying chamber may also incorporate safety features.
