    Abstract: An emulsion breaker featuring a two stage unit, the first stage comprising a resin impregnated fibrous medium including waterresistant, preferentially hydrocarbon-wettable synthetic fibers and having passages therethrough sufficiently fine to trap particles greater than 25 microns in diameter but at least coarse enough to permit passage of particles 1 micron in diameter, and a second stage directly downstream of the first comprising a batt including water-resistant, preferentially hydrocarbon-wettable synthetic fibers for removing from hydrocarbon droplets passing out of the first stage water bubbles surrounding those droplets.

    Abstract: Improvement in a system for controlling fluid temperature comprising a member movable between positions in which the temperature is respectively increased and decreased, and an actuator linked to the member and mounted to communicate with the fluid to adjust the position of the member in accordance with temperature changes in the fluid, the improvement being in the actuator, which comprises a housing; a diaphragm mounted in the housing to define a control chamber therein, the diaphragm having a valving portion and having a piston portion linked to the member and mounted to reciprocate in the housing, to move the member between its positions, the housing having an opening on one side of the diaphragm for connection to a source of regulating pressure, the valving portion being adjacent the opening and movable between sealed and unsealed positions with respect thereto; and a temperature sensitive element mounted to apply force to the valving portion dependent upon the fluid temperature, so that the balance of forces on the valving portion, including force attributable to the regulating pressure, will determine the position of the valving portion, and, in turn, the pressure in the chamber and the positions of the piston portion and the member.

    IPC: F04D29/38

    CPC classification number: F04D29/382

    Abstract: An automotive fan having flexible curved blades of resilient material which decamber as rotational speed increases in which an integral portion of each blade, having a mass of the order of 2 percent to 40 percent, preferably 8 percent to 10 percent, of the remainder of the blade, extends continuously along substantially the entire trailing edge of the blade and is folded upon itself at the trailing edge on the upstream side of the blade, thereby rigidifying and weighting the trailing edge to reduce vibration and noise and to assist the decambering of said blade at a predetermined rate.
