Abstract: An extreme vacuum cooling (EVC) method and apparatus is disclosed for rapid cooling, food treatment, and flavor infusion in commercial kitchens and food processing plants. Operating under ultra-low pressure with adaptive chamber pressure control, the EVC apparatus eliminates liquid splash and optimizes marinating and brining, achieving substantial time and energy savings. Available in single-unit and dual-module designs, this technology and apparatus enables swift, flexible, safer, less labor-intensive, and high-throughput food preparation operations.

Abstract: A well screen cover including a channel running along substantially the entire length of the well screen cover. The channel may be formed directly into the cover or separately formed and welded to the cover. The channel is open to the exterior of the well screen cover and is formed to house a cable, such as a fiber optic cable, which is run into a well bore along with the well screen.

Abstract: Well screen assembly for use in horizontal wells and other situations where tensile, torsion and bending forces can damage well screens which are welded to their end supports provides a floating mounting which eliminates welding of the screen segments. A pair of complementary inner and outer slip rings are provided at one end of the well screen assembly with the inner ring being in sealed relationship with a screen segment and the outer ring being integrally affixed to an outer protective cover member and an axial support member such as a pipe base member or a tubular end fitting. The inner ring is free to slide and rotate relative to the outer ring.

Abstract: Well casing assembly for use in oil and gas wells, and especially deviated or horizontal wells, has an inner pipe member with threaded ends which permit a number of casing assemblies to be joined in a string. The inner pipe has a series of perforations along a segment of its length which are covered by an elongated screen member which prevents the passage of sand particles. A concentric outer protective cover member is devoid of perforations in regions which are radially opposite the inner screen to prevent damage to the screen. One or more perforated segments of the outer member are axially spaced from the screen member so that inward flow from a formation will have its energy and velocity reduced before it reaches the screen, thereby minimizing erosion of the screen surface. If desired, perforated flow control devices such as annular rings can be located between the inner pipe and outer member at the ends of the screen segment to allow a more uniform flow to the screen, and thus further reduce erosion.

Abstract: An alternate-path, well screen made-up of joints and having a sleeve positioned between the ends of adjacent joints which acts as a manifold for fluidly-connecting the alternate-paths on one joint with the alternate-paths on an adjacent joint.

Abstract: Disclosed herein is an internal combustion engine comprising a cylinder block, a cylinder, an exhaust port, an inlet port, and a cylinder head fixed to the cylinder block including a recess, a spark plug fixed in the cylinder head along an axis located in a plane bisecting the inlet port and the exhaust port and extending at an acute angle to the cylinder axis, a fuel injector fixed in the cylinder head between the cylinder axis and the inlet side and along an axis located in the bisecting plane and extending in parallel and offset relation to the cylinder axis in the direction from the inlet port to the exhaust port, and a piston moveably axially in the cylinder and comprising an outer surface extending in opposing relation to the cylinder head and including a deflector extending diametrically from and between the cylindrical wall in transverse relation to the plane bisecting the inlet port and the exhaust port and including a centrally located raised crown having therein an axially inwardly extending bowl,

Abstract: Screen for use in collecting and/or distributing process flow streams has profiled surface wires welded to channel-shaped support members and is preferably made by helically wrapping and welding a profiled surface wire around the elongated channel members which are rotated about the screen axis to produce a cylindrical slotted screen which is then cut along a line parallel to its axis, flattened, and either used flat or rerolled and welded at right angles to its original direction so that the channels form hoop-like supports. The channels are preferably apertured to such an extent that the total open area for an inlet stream flow on the channel side of the screen is less than the open area of the slots on the wire side of the screen. Also, it should be noted that the outer edge of each leg portion of each of the channel members is positioned so close to the outer edge of a leg portion of an adjacent channel member that substantially all of the process stream will flow through the aperatures.
