摘要:
A method and apparatus for the detection of methane gas including a low-cost low-power infrared methane sensor integrated with a smart energy network endpoint node, a volume corrector, or an electronic data recorder for transmission of alarm conditions and detector data between the instrument and a remote gas utility company. An independent gas calibration/verification cell may be included in the methane detector for periodically testing the functioning and calibration of the infrared sensor. An infrared carbon monoxide sensor and associated calibration/verification cell may also be installed with the methane sensor.
摘要:
A method for preparing low toxicity Fischer-Tropsch fuels suitable for use in a diesel engine and Fischer-Tropsch derived fuel compositions having low toxicity suitable for use in diesel engines characterized by a boiling range distribution wherein the 5 weight percent point is at a temperature of 570 degrees F. or less and the 95 weight percent point is at or above a temperature of 680 degrees F.; a kinematic viscosity at 40 degrees C. of less than 5.5 cSt; and a cloud point of less than −18 degrees C.
摘要:
An assembly for maintaining flow between an inlet conduit and an outlet conduit. The assembly may include a first plate having an inlet notch sized to engage the inlet conduit and an outlet notch sized to engage the outlet conduit, and a second plate having an inlet notch sized to engage the inlet conduit and an outlet notch sized to engage the outlet conduit. The assembly may also include a first connecting member coupled to the first plate and the second plate, a bag having at least one glove port coupled to a second connecting member, and means for connecting the first connecting member to the second connecting member.
摘要:
A dosage form for administration of two or more active pharmaceutical ingredients to a subject, comprising a first pharmaceutical composition comprising a first active pharmaceutical ingredient and optionally one or more pharmaceutically acceptable excipients in a first physical form selected from the group consisting of powder, granule, pellet, bead or mini-tablet form, and at least a second pharmaceutical composition comprising a second active pharmaceutical ingredient and optionally one or more pharmaceutically acceptable excipients in a second physical form selected from the group consisting of granule, pellet, bead, mini-tablet or tablet form, wherein the composition is characterised in that said first and second physical forms are selected to be different to minimise interactions between said first and second pharmaceutical compositions and to allow separation of said first and second pharmaceutical compositions for analysis on the basis of size difference.

摘要:
A method an composition for the bonding fibres to rubbers. The method comprising the steps of the fibres with a primer, treating the fibres with a resorcinol/formalin/latex preparation and curing the rubber in intimate contact with the treated fibres, wherein the primer comprises a ring-opened, maleinised polybotadiene and a phenolic derivative comprising electron-withdrawing groups. The composition can be the primer alone or in combination with the primer alone or in combination with the resorcinol/formalin/latex preparation.
