Abstract: A system for crimping metal sheets and a female die designed for use in crimping metal sheets. According to the present invention, a female die for use by interaction with a male die to join metal sheets together by interaction of the dies to cut or slice through the sheets to form portions of the metal sheets which are spread by material flow by the interaction of the dies to prevent separation of the metal sheets is disclosed.
Abstract: A process for separating a feed gas stream containing methane, C2 components, C3 components, and heavier components into a volatile gas stream containing a major portion of the methane and C2 components and a less volatile stream containing a major portion of the C3 and heavier components by adjusting the temperature and pressure of the feed gas stream and charging it to a separator/absorber where the gas stream is separated into a first gas stream containing a major portion of the methane and C2 components with a minor content of C3 and heavier components and a first liquid stream containing a major portion of the C3 and heavier components with a lesser concentration of C2 and lighter components with the first liquid stream being fractionated in a deethanizer into an overhead stream and a bottoms stream with the bottoms stream containing primarily C3 and heavier components with the overhead stream containing primarily C2 and lighter components being at least partially condensed and separated into a liquid re
Abstract: A multi-stage compressor, including a system for the injection of a cooling liquid into at least a portion of the compressor stages to increase the efficiency of the multi-stage compressor by reducing the temperature of the compressed gas produced in the multi-stage compressor. A cleaning solution may also be injected through nozzles used for the injection of the cooling liquid.
Abstract: A method for converting well drilling cuttings that carry petroleum hydrocarbons to an environmentally friendly humus-like product wherein salt, if present, is washed therefrom, the washed cuttings mixed with a feedstock having a carbon and nitrogen content sufficient to encourage a biopile composting reaction, forming an environmentally acceptable plant growth enhancing humus-like product by continuing the biopile composting reaction until (1) the biopile is reduced in weight and/or volume to a total biopile weight and/or volume that approaches the original weight and/or volume of the drill cuttings before the feedstock was added thereto, and (2) the total petroleum hydrocarbon content of the biopile is reduced to an environmentally friendly level for spreading on the earth's surface.
Abstract: A toy for producing a concealed message by producing a message on a message paper including a busy reddish pattern and for revealing a concealed message from a second party on a message paper including a busy reddish pattern by viewing the message under a translucent member having a similar red color.
Abstract: A highly tensioned, suspended pipeline (HTSP) which is especially useful in permafrost regions, rugged terrain, and active seismic fault areas. Basically, the pipeline is comprised of segments which are fluidly connected together to form the desired length of the line. Each segment is comprised of a length of tensioned pipeline which extends between two fixed anchors and which is suspended over a plurality of vertical support towers therebetween. The length of pipeline is greater than the distance between the anchors to allow the pipeline to sag significantly between adjacent vertical supports whereby there is no need for expansion loops in the line.
Abstract: An electrophotographic apparatus having structure for mounting a drive motor on the fuser section whereby the motor can be removed and replaced from the outside of the housing. The structure includes a mounting structure which is affixed to one of the walls of the housing and an adapter plate which is affixed to the face of the motor. The mounting structure has a stub extension for receiving the gear on the drive motor and a plurality of mounting holes spaced outward therefrom. The adapter plate has a main opening to receive the hub of the motor and openings through which screws secure the plate to the motor. The plate has mounting openings which align with the mounting holes in the mounting structure to secure the plate, hence the motor, to the housing.

Abstract: A connector for connecting electrical conductors and including first and second conductor-containing bodies configured to sealingly connect the conductors when the first and second body are matingly joined. A passageway is formed to accept a pin when the first and second body are matingly joined so that the pin, which is a different color than the first and second body, is readily observable in position to confirm that the first and retains the first and second body in mating engagement and so that the pin, which is a different second body are matingly joined.
Abstract: A method and apparatus for extending the useful life of a fuser roller having ends, a length greater than a central portion of the fuser roller, the central portion of the fuser roller having ends, and end portions of the fuser roller extending from the ends of the central portion of the fuser roller to the ends of the fuser roller, at least a portion of the fuser roller being coated during operation with a release agent by contact with a wick roller, the wick roller including a porous ceramic wick roller body having ends, a length greater than a central portion of the wick roller, the central portion of the wick roller having ends, a release agent supply line in fluid communication with a central cavity in the wick roller body, a release agent impermeable coating over lengths of the wick roller body between the ends of the wick roller and the ends of the central portion of the wick roller, and a release agent transfer surface over the outside of the wick roller and the release agent impervious coating by pos

Abstract: A method for efficiently producing, transporting, offloading, storing and distributing a natural gas to a marketplace. The method comprising producing the natural gas from a first subterranean formation, liquefying the natural gas to produce a liquefied natural gas, transporting the liquefied natural gas to a re-gasification platform, offloading and pressurizing the liquefied natural gas, re-gasifying the liquefied natural gas to produce a re-gasified natural gas, and injecting the re-gasified natural gas into a second subterranean formation which is capable of storing natural gas and producing a product natural gas stream therefrom and transporting the product natural gas stream via a distribution system to a marketplace.
Abstract: A closed loop single mixed refrigerant process and system wherein the process efficiency is increased by increasing the temperature of liquefied material produced in a heat exchange refrigeration zone and thereafter cooling the liquefied material by flashing a portion of the liquefied material to produce a cooler liquefied material and a flash gas a portion of which is recycled to the heat exchange refrigerator. The process and system provide increased process efficiency and flexibility.
Abstract: An electrostatic filter for removing contaminants from a dielectric fluid when the filter comprises a plurality of electrically conductive plates positioned in a housing and having filter media disposed between the plates so that during the operation of the filters, fluid flows axially through the media between the electrode plates and into a central recovery zone and is discharged from the filter.
