Systems and methods for sensing angular motion in the presence of low-frequency noise
Systems and methods for sensing angular motion using a microelectromechanical system (MEMS) gyroscope are described. These systems and methods may be useful for sensing angular motion in the presence of low-frequency noise, which may be noise below 1 KHz. In a system for sensing angular motion, low-frequency noise may give rise to duty cycle jitter, which may affect the demodulation of the sense signal and cause errors in angular motion estimates. The systems and methods described herein address this problem by relying on double-edge phase detection technique that involves sensing when the rising and falling edges of the resonator signal deviate from their expected values in the idealized 50% duty cycle scenario. To prevent the formation of ripples in the double-edge phase detection that may otherwise affect the demodulation of the sense signal, a switch may be used.

Compressor gas cutoff
Embodiments of a compressor cutoff are presented. In an embodiment, the present invention includes apparatus for cutting off the flow of gas/liquid in the event of compressor failure or breakdown. In this embodiment, gas/liquid flows from its source through one or more passageways into a first input chamber, and also through one or more other passageways into a second input chamber, where the first and second input chambers are separated by a stop plunger. During the down-stroke of the compressor's piston, gas/liquid in the first chamber passes (or is drawn) through an inlet valve of the piston bore, and during the up-stroke of the piston that gas/liquid is forced through an outlet valve to a tank or other compressed gas/liquid receptacle. So long as the compressor operates normally, the pressure in the two input chambers (i.e., on each side of the stop plunger) will be substantially equal, thereby keeping the stop plunger in place. If, however, the compressor fails in a manner that exposes gas/liquid in the piston bore to the atmosphere, or otherwise results in a decrease in pressure in the piston bore, the pressure in the first input chamber will fall below the pressure in the second input chamber, thereby causing the stop plunger to move to a position in which it blocks the flow of gas/liquid from entering the inlet valve of the piston bore. |

Compositions containing anti-HIV ostrich antibodies
For many diseases due to microbes or the like, proliferation of microbes themselves is a cause of a symptom.

However, it was difficult to find the underlying substance causing the disease among substances released by the microbes. An antibody (polyclonal) binding to not only an antigen but also to a substance, which is secreted by the antigen and accelerates the deterioration of a symptom, is obtained by immunizing birds with a lysis solution produced from lysing microbial cells as an antigen. Further, an antibody obtained with a surface protein of a virus as an antigen is expected to inhibit an infection by a virus. |

Tannery process with effluent recycling
A recycling process for achieving near-zero emissions of tannery effluent is characterized in that effluent recycling is carried out independently in soaking, liming, re-liming, de-liming bating, pickling chrome tanning, re-tanning, neutralizing, and dyeing procedures. The effluents in the above procedures can be recycled in each step. This process greatly reduces effluent discharge and helps solve the problem of tanning pollution. The process also improves the quality of the finished leather, effectively decreases loose grain rate and increases compactness and fullness of the finished product. The project can reduce chemical material consumption by 15%-55%. For example, the consumption of chromium powder can be reduced up to 65%. Consumption of other chemical materials can be reduced by more than 90%, while certain chemical materials can be essentially completely conserved. |
