摘要:
Thermoplastic copolymers of glytaric anhydride and (meth)acrylic esters may be prepared free of acid groups by reacting a (meth)acrylic ester polymer with a secondary amine at elevated temperature, and subsequently removing volatile components from the polymer at elevated temperature and reduced pressure.
摘要:
A pump for supplying liquid fuel to an engine and which incorporates means, in the form of shear members, for degrading an anti-misting additive in the fuel.
摘要:
A pressure loaded gear pump comprising a housing, a pair of intermeshing gears positioned in the housing, at least one gear side face sealing member, and pressure loading means for defining a pressure loaded area in use of the pump, the pressure loading means comprising a bobbin and first and second axial seals mounted on the bobbin.
摘要:
Reverse osmosis liquid filtration apparatus, which apparatus comprises an inlet conduit, a reverse osmosis chamber, a pump for pumping liquid to be filtered from the liquid inlet conduit to the reverse osmosis chamber, a reverse osmosis membrane positioned in the reverse osmosis chamber and dividing the reverse osmosis chamber into a first portion for containing concentrated unfiltered liquid and a second portion for containing filtered liquid that has passed through the reverse osmosis membrane, a first outlet conduit which extends from the second portion of the reverse osmosis chamber and which is for the filtered liquid, a reservoir, reservoir separator means, a second outlet conduit for concentrated unfiltered liquid, and valve means.
摘要:
An arrangement for head-up display system components incorporated into an aircraft cockpit forward of the ejection plane (124) provides space for accommodating a head-down display device (132) immediately beneath the over-nose vision surface (128) and adjacent to the ejection plane (124). The arrangement of components minimizes the amount of angular change in the pilot's line of sight that is required when the pilot moves his head to change his view from the outside real world scene to the head-down display device.
摘要:
A pump for pumping a liquid containing solid contaminants, which pump comprises rotatable pumping means for pumping the liquid from a pump inlet to a pump outlet, a filter for filtering the liquid, auxiliary pumping means for pumping the liquid to the filter, first passage means for passing filtered liquid to at least one bearing in the pump for lubrication, a rotor device which is operative during use of the pump to cause the liquid inside the filter to swirl and clean the inside of the filter, and second passage means for allowing the passage of unfiltered liquid from the inside of the filter whereby the unfiltered liquid can remove separated solid contaminants on the inside of the filter.
