Abstract: A method of filtering a main fluid using a rotary fluid filter. A 360 degree filtration cycle is initiated by receiving, at an initial position, a first portion of a main fluid at a front end of a first fluid flow passage extending through a filter body rotationally mounted within a housing. The filter body is rotated in a rotation direction and the first portion of the main fluid is discharged from a rear end of the first fluid flow passage, having passed through a filter received in the first fluid flow passage. The filter body is rotated further in the rotation direction and a first portion of a backwash fluid is received through the first fluid flow passage from the rear end to the front end. The rotational cycle is completed by rotating the filter body back to the initial position.

Abstract: A turbine is provided, comprising a housing having a fluid inlet and a fluid outlet, each in communication with an internal chamber formed within the housing. A rotor is mounted for rotation within the internal chamber. At least one paddle is pivotally mounted to the rotor for pivoting between an extended position in which the paddle extends substantially radially from the rotor for receiving pressure exerted by fluid moving through the housing and causing the rotor to rotate, and a retracted position in which the paddle does not extend from the rotor. A cam is provided in the internal chamber for moving the paddle from the extended position to the retracted position when, during rotation of the rotor, the paddle moves past the cam in the extended position. Magnetic biasing means may be used to bias the paddle in the extended or retracted position.

Abstract: The invention is an environmentally safe surface cleaner with 3 main ingredients and an odor enhancing compound. The ingredients are sodium bicarbonate, triacylglycerol saturated and unsaturated fatty acids, and water. The odor enhancer can be mint or peppermint oil, or almond extract; or it can be excluded from the composition. The invention is effective on multiple surfaces including hard surfaces and fabrics. The 3 main ingredients all have more than one role, rendering the composition as an effective polar solvent and an effective non-polar solvent. The composition is used in conjunction with a hard plastic scraper or soft cloth or other physical scouring device with a harness of no more than 2.5 on Moh's hardness scale. The composition is an effective scouring agent that aids in breaking the bonds between atoms of the surface debris and atoms of the surface.

Abstract: A magnetic gate latch has a multiplicity of permanent magnets arranged on a pair of disks with half of the magnets in mutual attraction and half of the magnets in mutual repulsion. These magnetic forces are used to brake and close a gate or door. One of the disks is made axially movable with respect to the other so as to assume mutual repulsion in one position and mutual attraction in a second position. The movable disk is attached to a gate or door closing member and the other disk is attached to the closing structure post or jamb. Magnetic forces in the repulsion position are used in the invention to reverse the movable disk from a mutual repulsion position to a mutual attraction position.

Abstract: A rotary, positive displacement pump for fluids, having a pair of diametrically opposed vanes secured to a rotor in equally spaced, similarly contoured pockets, for movement between an extended position with a portion of the vane extending outwardly beyond the cylindrical surface of the rotor and a retracted position wherein the vane is seated entirely within its corresponding pocket. Each vane is formed of a top curved portion and a bottom curved portion, these portions meeting along a longitudinally extending line. The top portion extends from a pivot to the line and is curved so that when the vane is in retracted position it sits in a peripheral depression extending longitudinally along the rotor surface, the outer surface of this top portion of the vane conforming to the cylindrical surface of the rotor. The bottom portion is curved along a radius from that pivot, so that this lower portion is seated in and fills its corresponding pocket when the vane is in retracted position.

Abstract: A rotary fluid pressure actuator includes a housing having an inner actuator chamber with a cylindrical side wall extending between a pair of end walls. An integral vane rotor assembly, including a shaft and end discs, is positioned in the chamber and is rotationally reciprocated in response to the direction of flow of fluid to and from chamber segments of the housing. A fixed dam is secured between flanges in an elongated opening along the cylindrical side wall of the housing, the dam extending radially into the chamber from the opening to abut against the shaft between the end discs. The dam acts as a stop to limit the reciprocal motion of the vane and shaft in each direction.

Abstract: An impeller-type pump includes a housing with an internal chamber, a rotor within the chamber and a vane mounted to the housing for reciprocating action such that an end of the vane contacts the rotor and effectively divides the chamber between induction and exhaustion rotor chambers. The rotor has a non-circular cross-sectional configuration, such that its outside surface forms a camming surface that drives the vane in a reciprocating fashion upon rototation of the rotor. The rotor may be oval in cross section or have a complex cross-sectional configuration with a substantially flat trailing face forming a stop to prevent reverse direction rotation, and a curved leading face which forms a cam surface to elevate the vane upon rotation of the rotor.

Abstract: A rotary piston pump comprising a rotor mounted within a housing, the rotor having a pair of slidably mounted vanes on opposite surfaces. The inner wall of the housing acts as a cam surface to move the vanes inwardly, and centrifugal force or a combination of centrifugal force and biasing causes the vanes to move outwardly. The rotor is eccentrically mounted within the housing and the housing interior walls are of irregular configuration, whereby fluid from an inlet is moved by the vanes through the housing to an outlet. This rotary piston pump is of economic construction, serves a variety of applications and is easy to service.

The vanes are biased outwardly and forced inwardly by a cam action of the interior wall of the housing of the piston. Operation of the piston may be facilitated by the use of peripherally mounted drive gears. The rotary piston according to the present invention is particularly useful in pumping fluids and provides a system that can operate at both high and low speeds for a wide range of liquid viscosities.
