摘要:
A method for the extraction, separation, fractionation and purification of biopolymers from plant materials using supercritical and/or subcritical solvent extractions is disclosed. Specifically, the process can be used for the separation of resins and rubber from guayule shrub (Parthenium argentatum), and other rubber and/or resin containing plant materials, using supercritical solvent extraction, for example supercritical carbon dioxide extraction. Additionally, polar and/or non-polar co-solvents can be used with supercritical carbon dioxide to enhance the selective extraction of resins and rubbers from the shrub.

Disclosed is a method and apparatus for the extraction of high molecular weight biopolymers from plants. Specifically, invention described herein relates to the commercial processing of plant material, including that from desert plants native to the southwestern United States and Mexico, such as the guayule plant (Parthenium argentatum), for the extraction of biopolymers, including natural rubbers. More specifically, the invention relates to laboratory to commercial scale extraction of high molecular weight biopolymers from plant materials including the chemical and mechanical processing of the plants and purification of the extracted biopolymer.
摘要:
An injection device is for use with a syringe having a bore extending from an end surface, a needle communicating with the bore through the end surface and a dispensing piston movable in the bore towards the end surface. The injection device includes a housing having an opening, a resilient member for biasing the syringe and needle inwardly of the housing, a drive element movable towards the one end so as to move the needle out of the opening against the bias of the resilient member, a delatch mechanism operable to release the syringe such that the needle moves inwardly of the housing, and a drive coupling. The drive coupling gradually reduces in length such that, after the drive element has moved the dispensing piston to the end surface, the drive element continues to move to the dispensing piston at the end surface.

A vehicle wash system is set forth that comprises a main carriage that is movable along a length of a vehicle that is to be washed and a carriage drive system disposed to move the main carriage along the length of the vehicle. A plurality of nozzles are disposed for co-movement with the main carriage to dispense fluids used in the washing of the vehicle. A sidearm drive system is disposed for co-movement with the main carriage. The sidearm drive system rotates a sidearm cloth in a reciprocating manner for contact with a side portion of the vehicle. To reduce the footprint needed to operate the wash system, the sidearm cloth may be rotated along an arc that is less than 360°. An overhead cloth drive system also may be disposed for co-movement with the main carriage. The overhead cloth drive system may move an overhead cloth in a reciprocating manner for contact with an upper portion of the vehicle.

The present invention provides a facility management platform to monitor and view the status of a plurality of individually addressable downstream devices including, but not limited to, addressable terminals, IRG's, settops, cable modems, taps, nodes, and/or hubs at a network control center. The FMP may display problems at these downstream devices, for example, power loss, and/or may automatically notify the appropriate companies and/or personnel to correct the problem.

A filter assembly for a fresh air filtration system, the fresh air filtration system made therewith, and a method of filtering fresh air are provided. The filter assembly includes a filter housing and at least one filter element supported within the housing, the housing having at least one inlet for receiving a fluid to be filtered and at least one outlet for discharging filtered fluid, wherein the at least one inlet and at least one outlet are on a common side of the housing.

A method and a process for the production of high pressure laminate is disclosed using conventional manufacturing equipment without the use of melamine-formaldehyde resin pre-impregnated decorative print, solid, or overlay papers or combinations thereof. The method and process of making the disclosed laminate product utilize the assembly of a plurality of pre-impregnated Kraft papers independently saturated with melamine-formaldehyde resin, phenol-formaldehyde resin, and/or a bilayer coated construction of Kraft paper simultaneously containing both resins on opposing surfaces. The resulting pre-impregnated Kraft based components are assembled into the core layer and combined with the desired decorative layer assembly composed of untreated decorative print, solid, and/or overlay papers, or combinations thereof, prior to consolidation into a finished laminate using standard heat and pressure commonly known to those skilled in the art.

Locating satellites (e.g., GPS) are culled into a sub-plurality based largely on dwell time within an inverted cone above a relevant site in communication with a wireless device. A first inverted cone having a first base angle is defined above a first site, a second inverted cone having a second base angle is defined above a second site. If the second site is farther from an equator of Earth than the first site, then the second inverted cone is made to have a base angle larger than a base angle of the first inverted cone. If the first site is farther from the equator of Earth than the second site, then the first inverted cone is made to have a base angle larger than a base angle of the second inverted cone. The span of the inverted cone over the site closest to the equator may be limited.
摘要:
A cushioning device as in a pillow that has a main-body foam which a plurality of projections extend off a surface of the main-body. The projections are arranged in different support characteristic groupings such as rows of different volume or sized projections (e.g., cylindrical, cubical, prismatic, etc.) spaced out over a surface (e.g., convex surface) of the pillow (one or more surface sections as in upper surface sections and front edge surface section). There is also preferably provided a neck support ridge extension. The cylindrical projections are arranged such that a greater number of smaller volume, width or diameter, etc. rows of projections are centrally positioned on the surface and with the larger volume, width, or diameter, etc. projections laterally outward of the more centrally positioned projections, and with the ridge extension preferably extending along a front edge (e.g., commensurate with the extreme front edge surface or to some extent back in a front edge region of the front edge) of the pillow for a full length of the pillow.
