Abstract: A plow assembly for forming a trench within soil of a selected land area. The plow assembly has a blade element, a displacement element, and an attachment element that permits attachment of the plow assembly to a vehicle, such as a tractor. A first end of the displacement element is secured to a distal end of the blade element, and a second end of the displacement element is spaced from a rear edge of the blade element and connected to a pipe. As the plow assembly is advanced within soil, the cutting edge of the blade element cuts through the soil and the displacement element displaces the soil to form the trench and pulls the pipe into the trench as the trench is formed.

Abstract: Disclosed herein are methods of inducing and/or promoting cardiomyocyte maturation comprising: providing an immature cardiomyocyte; providing a three dimensional (3D) cardiac extracellular matrix (ECM) scaffold; and inducing and/or promoting cardiomyocyte cell maturation by seeding the immature cardiomyocyte in the 3D cardiac ECM scaffold and harvesting once the cardiomyocyte has reached maturity. Also disclosed herein are methods of treating a disease in a mammal comprising transplanting a mature cardiomyocyte into an ischemic heart, wherein the mature cardiomyocyte is generated comprising the steps of: providing an immature cardiomyocyte; providing a 3D cardiac ECM scaffold; and generating mature cardiomyocyte by seeding the immature cardiomyocyte in a 3D cardiac ECM scaffold or co-culturing the immature cardiomyocyte in the presence of endothelial cells or stromal cells; and harvesting once the cardiomyocyte has reached maturity.

Abstract: An oxygen fired fluidized bed combustor system (Oxy-FBC) is provided. The system provides means of producing a nearly pure stream of carbon dioxide for storage at high efficiency by controlling the oxygen content within certain regions of the combustor to control the rate of heat release allowing efficient transfer of heat from the combustor to the boiler tubes while avoiding excessively high temperatures that will cause ash melting, and simultaneously remove sulphur from the combustor via sorbents such as limestone and dolomite. The present invention utilizes a coarse oxygen carrier bed material to distribute heat and oxygen throughout an Oxy-FBC, while injecting fine sulphur sorbent that will continuously be removed from the bed.

Abstract: Film-forming compositions are provided comprising: (a) a zwitterionic-functional polymer; and (b) an organometallic compound. Also provided are methods of reducing adhesion of an organic substance to a substrate and methods of treating a siliceous or metal (M) oxide-containing subterranean formation penetrated by a well using the film-forming compositions described above.

Abstract: The present invention provides a wet press process and admixture components for making concrete slabs (flags), curb (kerb) units, panels, boards, and other flat shapes, whereby colloidal silica and at least one alkanolamine and optional rheology control components are employed to provide an ideal combination of pressing time, green strength, surface definition, stack-ability, final concrete strength, and permeability. Stack-ability can be expressed in terms of minimum deflection or non-eccentricity of the units while standing on thickness edges at distances apart less than width or standing height. A wet press process typically involves introducing a highly fluid concrete mix into a mold, applying hydraulic pressure to consolidate the concrete (e.g.

Abstract: An apparatus that may entirely be contained in a glovebox for the removal of at least one contaminant from an inert atmosphere. The apparatus includes a body, a media in the body for the removal of at least one of the contaminants from the inert atmosphere flowing through the media, a fan for causing the inert atmosphere to flow through the media and body, and a motor for driving the fan. The apparatus may be provided in combination with a glovebox. A method of purification of the inert atmosphere using such an apparatus is also provided.

Abstract: The present application discloses a string light assembly, such as for example, a string light assembly for task lighting in an industrial or transportation environment. In certain embodiments, an exemplary lighting device includes a length of electrical cable, at least one socket secured to the electrical cable, and at least one cover that encases the socket. The cover is secured to the electrical cable by placing the electrical cable in a through hole of the cover. In addition, the cover comprises a first connection port configured to receive an end of an electric lamp and a sloped surface that extends between a portion of the cover having the through hole and the connection port.

Abstract: A trunk mounted storage rack for sport utility vehicles (SUV) securely restrains grocery bags and prevents damage to fragile items contained therein. The trunk mounted storage rack includes a top shelf, a bottom shelf, a top lip, a bottom lip, a top-level barrier, an intermediate support frame, and a barrier support wall. The top shelf and the bottom shelf are sized to closely fit in the trunk of the SUV. The intermediate support frame suspends the top shelf over the bottom shelf. The barrier support wall allows the top-level barrier to mount to the top shelf and prevent items from falling from the top shelf into the rear seat compartment when the SUV turns or brakes.

Abstract: A lamp includes a light tube and one or more circuit boards. The light tube has three or more securing elements that extend along a length of the light tube. The circuit boards have a plurality of LEDs. The light tube is configured such that the one or more circuit boards are secured to an interior of the light tube by an adjacent pair of the three or more securing elements.

Abstract: A nut fastener is provided for locking the nut to prevent inadvertent loosening of the nut. The nut fastener is particularly useful for tightening a wheel onto an axle. The nut fastener includes a nut, a collar and a retaining ring. The nut is unlocked by pushing on an engagement surface of the collar or by riding ratchet teeth over each other. When the collar is released, the collar locks against the nut to resist rotation of the nut.

A first end of the displacement element is secured to a distal end of the blade element, and a second end of the displacement element is spaced from a rear edge of the blade element and connected to a pipe. The displacement element has a variable diameter that increases moving from the first end of the displacement element to the second end of the displacement element. As the plow assembly is advanced within soil, the cutting edge of the blade element cuts through the soil and the displacement element displaces the soil to form the trench and pulls the pipe into the trench as the trench is formed.

Abstract: A trunk mounted storage rack for sport utility vehicles (SUV) securely restrains grocery bags and prevents damage to fragile items contained therein. The trunk mounted storage rack includes a top shelf, a center shelf, a bottom shelf, an upper support frame, a center support frame, a lower support frame, a safety net, and a top-level barrier. The top shelf, the center shelf, and the bottom shelf are sized to closely fit in the trunk of the SUV. The center support frame suspends the top shelf over the center shelf. Similarly, the lower support frame suspends the center shelf and the top shelf over the bottom shelf. The upper support frame allows the top-level barrier and the safety net to mount onto the top shelf. The safety net prevents grocery bags from falling out of the back of the top shelf, the center shelf, and the bottom shelf.
