A furnace control system for controlling a gas-fired induced-draft furnace having a variable speed inducer blower. A control apparatus, responsive to a signal corresponding to the magnitude of a pressure difference between an inlet and outlet of the combustion chamber, controls blower motor speed to maintain the pressure difference at a predetermined magnitude corresponding to a selected gas flow rate. Inducer blower motor speed is varied directly and precisely to maintain an optimal pressure drop across the combustion chamber. The control system can be used in multi-stage and modulating furnace systems and in furnace systems utilizing pressure-assist modulating gas valves.

Disclosed are methods and devices for detection of bacteria based on recognition and infection of one or more selected strains of bacteria with bacteriophage genetically modified to cause production of an inducer molecule in the bacterium following phage infection. The inducer molecule is released from the infected bacterium and is detected by genetically modified bacterial bioreporter cells designed to emit bioluminescence upon stimulation by the inducer. Autoamplification of the bioluminescent signal permits detection of low levels of bacteria without sample enrichment. Also disclosed are methods of detection for select bacteria, and kits for detection of select bacteria based on the described technology.

A medium and high pressure pump systems supplies a cryogenic fluid from a storage tank. The system comprises a pump that is operable to pump cryogenic liquid or a mixture of cryogenic liquid and vapor. The pump preferably comprises an inducer with at least two chambers and means for recycling excess fluid within the inducer instead of returning excess fluid to the storage tank. The reciprocating pump is preferably double acting such that fluid is discharged from the pump during both extension and retraction strokes.

The invention relates to a plant stress-resistant inducer, which takes Chitosan oligosaccharide solution as an effective active component. The invention adopts Chitosan oligosaccharide to induce crops to resist drought, waterlog, cold and freeze. Leaves of the crops are sprayed with the Chitosan oligosaccharide or roots of the crops are irrigated with the Chitosan oligosaccharide in order to induce the stress resistance (drought, waterlog, cold and freeze resistance) of the crops. By inducing the leaves of the crops, the content of resistant enzyme is increased in different degrees; the praline content is obviously increased; the opening degree of stomata obviously declines; the chlorophyll content is obviously increased; and the stress resistance of the crops is improved. The external application of the Chitosan oligosaccharide can improve the stress resistance of the crops, is free from toxicity, causes no environmental pollution, and is simple in usage.
