Title: Irregular tessellated building units
Inventor: RICCOBENE THOMAS S
IPC: E01C5/00
Filed: 2004-03-24
Granted: 2012-05-22
Abstract: An irregular, tessellated building unit comprises x primary elements, wherein x is an integer equal to or greater than 1. The primary element (20) is a rotational tessellation having a plural pairs of sides extending in a generally radial direction from plural vertices, respectively. In each pair, the two sides are rotationally spaced by an angle that is divided evenly into 360 degrees. Preferably, all of the sides are irregularly shaped, but one or more sides could be wholly or partially straight. Optionally, spacers are provided on the sides of each unit. A wide variety of units may be constructed having different numbers and arrangements of primary elements (20). As all the units are combinations of primary elements (20), they readily mate with each other. A surface covering (10) comprises a multiplicity of units assembled to form a continuous surface without overlap between units and without substantial gaps.

Abstract: A method of removing water (7) from a fuel tank (2) using a water scavenging line (4) which has an inlet (6) immersed in the water and an outlet (5) coupled to a water tank (3). The method comprises filling the fuel tank with fuel (30) whereby the fuel exerts hydrostatic pressure on the water, the hydrostatic pressure driving the water up the water scavenging line against the force of gravity and into the water tank. The use of hydrostatic pressure provides an automatic and relatively simple method of extracting the water from the bottom of the fuel tank. The water tank enables the extracted water to be stored for disposal at a later time, typically by feeding the water into an engine.

Abstract: A positive displacement pump for pumping fluids from a downhole formation to the earth's surface is provided. The pump (100) first comprises a plunger (130). The plunger is reciprocated axially within the wellbore by a linear actuator (300), such as a submersible electrical pump, in order to form an upstroke and a downstroke. A pump inlet (140) is disposed near the bottom end of the plunger, while a pump outlet (150) is disposed near the top end of the plunger. The pump is configured such that it is able to pump a first volume of fluid upward within the wellbore during the pump's upstroke, and a second volume of fluid upward within the wellbore during the pump's downstroke. Thus, the pump is "double-acting", that is, it is able to displace fluids both on the downstroke and on the upstroke. The pump also permits the capture of a greater volume of fluids without a corresponding increase in velocity of the fluids through the pump. Furthermore, the pump is substantially hydrostatically balanced.

Granted: 2014-06-03
Abstract: A disposable cartridge assembly for use with a paint spray gun is disclosed, being made out of an inexpensive material, such as plastic, wherein the paint flows into the cartridge assembly and is sucked out of the tip of the cartridge assembly by the force of pressurized air flowing around the cartridge assembly and past the cartridge assembly fluid spray tip opening, thereby atomizing the paint, allowing for an even application of the paint onto a working surface, such as an automobile body. The inexpensive material allows the cartridge to be disposed of after use, rather than cleaned. Further, keeping the paint within the cartridge assembly and away from any inner workings of the paint spray gun reduces or eliminates the need to clean the spray gun after use.
