Abstract: A method and an apparatus are provided to remote boot a diskiess computer on a WAN. The remote boot apparatus is constructed as an embedded interface in the computer. The remote boot apparatus has a bi-directional buffer, a central processor, a network interface, a boot ROM and ail interface core routine. The remote boot apparatus intercepts a normal disk read of an MBR issued by a system BIOS of a local computer, and then redirects the disk instruction in a form of TCP/IP packet to a remote boot server to read a corresponding file block from a location of the remote boot server. After the file block is received and confirmed by the computer, the received file block is unpacked and supplied to boot the computer.

The remote boot apparatus has a bi-directional buffer, a central processor, a network interface, a boot ROM and an interface core routine. The remote boot apparatus intercepts normal disk read of an MBR issued by a system BIOS of a personal computer, and then redirects the disk instruction in a form of TCP/IP packet to a boot server to read a corresponded file block from a location of the server. After the file block is received and confirmed by the computer, the received file block is unpacked and supplied to boot the computer.

Abstract: A continuous dynamic mixing assembly includes a mixing chamber having an inner wall which is generally symmetrical about a central axis. At least one first fluid inlet introduces first fluid material into the mixing chamber. At least one second fluid inlet introduces second fluid material into the mixing chamber. At least one outlet permits fluid to leave the mixing chamber. First baffles extend along the inner wall generally parallel to the axis for disrupting fluid flow generally circumferentially in the mixing chamber. Second baffles extend generally transverse to the axis for disrupting fluid flow generally axially in the mixing chamber. A rotatable agitator includes a cylindrical central portion extending in the mixing chamber along the axis and has at least one blade having a twisted orientation on the central portion. A relative construction and arrangement among the first baffles, the second baffles and the agitator enable residence time of fluid in the reactor to be selectively adjusted.

Abstract: A vehicle and method for storing ozone is disclosed. A vehicle made of a water miscible, organic compound of a glycol-containing chemical compound, a tertiary alcohol or a mixture thereof that is capable of receiving and containing ozone is disclosed. The method involves producing ozone gas, introducing the ozone-containing gas into a mixing vessel that contains the aforementioned organic compound, agitating the organic compound in the presence of the ozone-containing gas, wherein the ozone-containing gas is at atmospheric pressure or at a pressure of up to about 150 psig., and releasing the pressure if pressures in excess of atmospheric are used.

Abstract: The present invention relates to a continuous dynamic mixing assembly comprising a pump assembly for motivating a fluid material into a mixing chamber and substantially preventing reverse flow of gas and/or fluid material and a continuous dynamic mixing chamber assembly for efficiently treating fluid material, the continuous dynamic mixing chamber comprising a cylindrical inner wall, elongated baffles coaxially extending along the major portion of the length of the inner wall, porous inserts for introducing gas into the mixing chamber and a multibladed agitator.

Abstract: A compact, heavy duty mixer-reactor is described which features a double-stage mixing/reaction chamber, one stage being of wall-baffled design and the other being unbaffled. Said mixer-reactor operates with a unique, two-stage impeller having a different set of coextensive agitator blades within each of said stages. For example, the effective radii of the blades in said unbaffled stage are significantly larger than those of the blades in said baffled stage. In addition, other differences in shape and pitch of the respective sets of agitator blades are provided to give enhanced performance, particularly in mixing and reacting finely divided solids with gases. The subject apparatus delivers outstanding results in terms of expediting thorough mixing and promoting complete reactions between fine solids and gaseous reagents. These results are particularly noteworthy when treating non-Newtonian suspensions of solids and liquids (e.g.

Abstract: Improved mixing equipment of the wall-baffled, cylindrical, mixing-vessel type is provided. The novel baffles employed have a uniform cross-sectional form corresponding generally to a small geometric segment of a circle, the radius of which circle is substantially equal to that of the inner wall of said mixing vessel. A plurality (e.g., 2 to 4) of such baffles mounted at uniformly spaced locations around the periphery of said inner wall are employed together with a concentrically located, multi-bladed impeller capable of providing good axial and radial mixing within said vessel.The subject mixing equipment can deliver outstanding performance in terms of speed and completeness of mixing, as well as economy in power consumption and peak power requirements. Results are especially noteworthy when the equipment is used to mix chemical reagents (gaseous or liquid) with thick, non-Newtonian suspensions of solids and liquids; e.g., wet wood pulps and similar compositions containing fine, fibrous solid matter.

Abstract: A safe continuous process is disclosed for generating superatmospheric pressure mixtures of chlorine and chlorine dioxide, wherein the chlorine dioxide is generated in situ by chemically reducing inorganic chlorates in aqueous sulfuric acid solutions, and most of the chlorine is supplied from a high-pressure external source. The mixed gaseous products contain Cl.sub.2 and ClO.sub.2 in volumetric Cl.sub.2 /ClO.sub.2 ratios of at least 10/1, and preferably between about 11/1 and 99/1, and are ideally suited for direct use in various industrial treatments, notably in the purification and bleaching of wood pulp and the like.

Abstract: A continuous system, process and associated apparatus are disclosed for reacting a gas with a liquid to manufacture a gaseous or liquid product. The preferred system comprises a reactive gas, such as chlorine and an aqueous solution, such as caustic soda, which are continuously combined and reacted under largely superatmospheric pressure and in turbulent cocurrent flow in very compact reactor equipment. Liquid bleach solutions such as aqueous solutions of hypochlorites or hypochlorous acid are among the products of major interest. The main reactor equipment consists of a fluid pressure energized, in-line mixing device followed by a low slip (closely fitted) regenerative turbine pumping unit. The fluid ports in the closely fitted stator elements of said pumping unit should have a radial dimension equal to at least about half that of the vanes.

The preferred composition is in an aqueous solution adjusted to an optimum pH and is used as a direct replacement for conventional compositions so as to effect substantial savings in the costs of chemicals and energy per ton of bleached pulp.

Abstract: A disinfection process is provided for preparing potable water having an unusually persistent and long lasting free available chlorine residual in order to assure safety and integrity of said water during its passage through the distribution system by which it is delivered to the consumer. The key step of this process is the generation of said unusually persistent free chlorine residual by mixing into a semi-finished water, which has already been pretreated specifically to satisfy substantially its immediate chlorine demand, dilute solution of HOCl having a pH between about 3 and about 6.
