Abstract: A sand check filter for preventing solids from reentering into a pump. The filter is designed to mount atop a conventional rod pump. The filter allows well fluid, that contains high solids, to pass through the pump under normal operation while eliminating the solids from being swept back into the pump barrel. The filter includes a sleeve that has radial flutes that allows the sleeve from hanging up, sticking to or wedging itself to the valve rod. The sleeve is rotated on the valve rod to create a valve effect atop the filter. This prevents the fluid from passing through the inner diameter of the screen and forces solids within the fluid to be redirected to the outer diameter of the filter. This allows the fluid to be filtered before reentering the pump.

Abstract: Provided herein is a shallow-liquid strainer apparatus with an intake assembly that can be adjusted to keep the inlet opening completely submerged beneath the surface of the liquid to avoid letting the surrounding atmosphere into the device where it can cause inefficient flow. The intake assembly can comprise a sliding door on tracks designed to cover all or a portion of the inlet. The apparatus can be connected to a pump. The wall of the device on which the inlet is located and the inlet itself can be angled toward the back wall to facilitate submerging of the inlet. The device can comprise a strainer attached to the inlet for removing undesirable elements from the liquid. A ramp can be provided near the inlet to allow the liquid to flow upward toward the outlet. Methods of making the device are also provided.

Abstract: An adjustable liner, for immersion in the cooking oil of a deep fryer, includes: (a) two partial baskets, each having a bottom surface with four edges and three side surfaces, each of which extends upwardly from one of the bottom surface's edges so that the fourth edges of these partial baskets are free edges, (b) wherein the bottom surfaces of each of these partial baskets has a porosity chosen so as to allow the cooking oil to circulate through these bottom surfaces when the deep fryer is in use, and (c) wherein the lengths of these partial baskets' free edges are such as to allow one of these partial baskets to fit and nest within the other so as to yield a liner having adjustable length that can be custom fitted to the width of the deep fryer in which this liner is to be retrofitted for use.

Abstract: A crude oil removal device that is attached to a tethered umbilical line which feeds coolant thru the coolant coils. The refrigerated device creates an atmosphere to which crude oil will attach itself to, either floating or submerged for easy removal. The unit consists of two housings that contain the cooling coils which is sealed with rubber to maintain an air tight seal. The unit does not collect water while collecting the crude oil and can be used in virtually any weather condition.
