Abstract: AXIAL SEALING DEVICE FOR A SCROLL-TYPE     FLUID DISPLACEMENT APPARATUS          ABSTRACT        A scroll-type fluid displacement apparatus is disclosed having a pair of scroll members each comprising an end plate and a spiral wrap extending from one side of the end plate. The spiral wraps interfit at an angular and radial offset to make a plurality of line contacts to define at least one pair of sealed-off fluid pockets. At least one of the scroll members has a discharge port or fluid hole near the center of the spiral element and is provided with an anti-wear plate on its end surface facing the other scroll member. The anti-wear plate is an involute plate that covers substantially the area of the end surface of the end plate on which the spiral wrap of the other scroll member makes contact during the orbital motion of the orbiting scroll member.      The radially inner end of the anti-wear plate is spaced from the dis-charge port to avoid blocking the discharge flow or covering the dis-charge port. Therefore, the undesirable vibration of the anti-wear plate by fluid flowing through the port is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE           A molded cup-shaped dielectric and a cup-shaped conductor are pressed together in telescoping relationship at an interference fit, whereby the two cup-shaped members comprise an integral dimensionally stable sealed enclosure for a contact member movable axially therein for selectively making or breaking an electrical connection between the cup-shaped conductor and a second conductor extending axially through and sealed within the base of the cup-shaped di-electric.  The axially outer surfaces of the base of the cup-shaped dielectric and the second conductor comprise electri-cal contacts for a gravity actuated switch adapted to be selectively and releasably confined between a pair of axially spaced contacts within a container for the switch.          The overall axial dimension between the axially outer sur-faces is preselected without recourse to close axial tolerances in the fabrication of the cup-shaped members, merely by telescoping the cup-shaped members coaxially to-gether until the preselected axial dimention is obtained.          In one embodiment the cup-shaped dielectric,has a cylindrical base and a coaxial diametrically reduced cylindrical portion extending from the base to an upper opening. The conductor-is telescoped over the diametrically reduced portion in fluid sealing relationship, whereby said enclosure has an interior cylindrical surface of optimum diameter for the axially movable contact member comprising a metallic ball also of optimum diameter for any given size switch.

Abstract: SELF-STABILIZING DRY VISCOUS SPRING DAMPER         Abstract of the Disclosure A self-stabilizing dry viscous spring damper is provided for absorbing shock that is particularly resistant to instability due to nonaxial deformation.  The damper comprises opposed first and second outer housing members which are elastomerically associated with a shear spring.  A selectively pressurizable gas chamber is provided having a subchamber disposed in association therewith which in-cludes, preferably, a plurality of elastomeric particles.  A rigid structural assembly with deformable bushing and metal bearing mem-bers is included in the damper for stabilizing the device upon relative compressive movement of the first and second outer housing members.  That is, the deformable bushing is provided to allow con-trolled nonaxial deformation to a maximum predetermined limit.  Past this maximum deformation limit nonaxial forces are entirely carried by the rigid assembly.  An inner housing is provided which includes outer wall portions configured in an arcuate bell-like configuration to engage the deformable elastomeric shear springs upon compression of the damper.  The form of the inner housing wall portions allows engagement of the shear springs in a nonfrictional manner.

Abstract: Abstract of the Disclosure Dual interrelated distillation columns are disclosed wherein the heat for a first column is transferred by thermal conduction through a common wall or surface to a second column to increase efficiency and decrease waste of energy.  In one embodiment, the first heat generating column is a cylindrical column, and the second column is an annular column concentric to the first column.  This concentric arrangement permits the heat generated in the first column to flow outwardly into the second column, thereby improving its efficiency and reducing the heat loss.  Typically, the inner first column is a high pressure rectifying column, and the outer con-centric column is a stripping column.  In an alternate embodiment, the inner column can simply be a portion of a high pressure distillation process, and the outer column is a portion of a lower pressure distillation column.  In alternate embodiments, the rectifying apparatus can assume a variety of shapes such as a plurality of packed tubes which extend through the stripping column or a corrugated configuration or rectangular configuration as desired.

Title: Method of producing a stratified viscous oil reservoir

IPC: E21B43/24
Filed: 1985-07-25
Granted: 1987-11-17
Abstract: ABSTRACT         This invention discloses a more efficient and more self supporting method of producing oil from a viscous oil-bearing permeability stratified reservoir.  In situ combus-tion with oxygen is carried out near a first injection well in a manner such that carbon dioxide substantially free of nitrogen is produced.  The carbon dioxide substantially free of nitrogen produced by in situ combustion is then injected into a second injection well to swell, reduce the viscosity of in-place oil and displace oil from a separate part of the stratified reservoir.  Water with or without other mobility and solubility control agents can be injected in either or both the combustion step and carbon dioxide displacement step.  In situ combustion with or without nitrogen may there-after be initiated adjacent the second injection well to produce the less permeable or more viscous oil-bearing strata to either produce oil left by carbon dioxide injection or to produce more nitrogen-free carbon dioxide.  This additional carbon dioxide plus carbon dioxide produced in the second production well can then be injected into a third laterally spaced injection well to sweep and displace oil from another part of the reservoir.  These steps may be repeated until the reservoir is economically depleted.

Abstract: ABSTRACT           The machine disclosed herein is useful for blending a particle containing stream, especially a stream of solid particles, with fluids.  In a typical operation, sand is mixed with a gel composition to obtain a fluid mixture suitable for stimulation treatments of oil and gas wells.  The machine includes a slinger with a topside surface which may be of toroidal concave configuration.  The machine also includes an impeller, of a vortex configuration, that is fastened underneath the slinger.  In this machine, entrained gas is carried into the fluid phase by the particle containing stream, but the gas is then "exhausted" from the mixture through interior and exterior air exhaust channels and spaces that are built into the machine.  A slinger which is particularly adapted for use in such a machine is also disclosed.
