The water reservoir also has a rotary agitator blade immersed therein with apertures to increase agitation.

Abstract: The effluent of a process for making a preform from which an optical fiber is drawn is directed into a scrubber (40) of a loop (20) where it is treated with an aqueous solution to provide a solvent mixture which comprises particulates and a solvent solution including germanium. Subsequently, the solvent mixture is moved into a first filter system (55) which provides a filtrate free of particulates above a first size that is returned to the scrubber for reuse and a residue. Then the residue from the first filter system is moved into a second filter system (80) which provides a filtrate free of particulates larger than a second size that is smaller than the first size and a residue. The filtrate from the second filter system also is returned to the scrubber for reuse while the residue from the second filter system is recirculated therethrough.

Abstract: Filter apparatus and a method for removing dry combustible particulate material from a stream of gas in two steps of separation, utilizing a primary separator to remove the majority of the material from said stream of gas and a secondary filter apparatus which includes water sprays and a wetted filter pad to remove additional material. Portions of the filter pad are sequentially backwashed at periodic intervals, and the particulate material washed from the filter pad is thereafter introduced into the stream of gas being cleaned, permitting collection of all removed particulate material from a single collection point associated with the primary separation apparatus. The material washed from the filter pad of the secondary apparatus is introduced into the stream of gas to be cleaned in the form of a slurry, the moisture from the slurry thereby reducing the likelihood of explosion of the particulate matter within the stream of gas.

Abstract: A fuel control system for gasoline operated vehicles includes a metering device connected to the fuel line for controlling the rate of flow to the carburetor to permit a normal rate under ordinary driving conditions and an increased rate of flow under accelerated conditions with a filter being connected to the fuel line upstream from the metering device to prevent blockage of the main metering valve in the metering device and a second filter downstream from the metering device to act as a auxiliary reservoir.

Abstract: A liquid fuel purification system has a centrifuge in parallel with a conventional filter. Both the centrifuge and the filter are in fluid communication with a reservoir of liquid fuel and with a user of liquid fuel, such as an internal combustion engine. A by-pass valve device selectively effects the movement of fuel through either the centrifuge or the filter responsively to centrifuge speeds. The latter, in a preferred embodiment, is responsive to engine speeds.
