Patent number: 6337048Abstract: A method and apparatus for significantly increasing the solubility and dispersibility of consumer products such as food products, botanicals, cosmetic ingredients and medical products is disclosed. The method involves applying a continuous stream of oxygen-containing, i.e., OX gas to a material in a sealed chamber. The continuous stream of OX gas is prepared in an OX generation cell, which contains a means for generating the OX gas at a pressure less than 20 lbs/in2 using, for example, one or more of the following: corona discharge, high frequency electrical discharge, ultraviolet light, x-ray, radioactive isotope and electric beam. The apparatus contains: (a) a chamber; (b) a vacuum pump coupled to the chamber; (c) an OX generation cell, wherein the OX generation cell contains an OX generator capable of generating OX at a pressure less than 20 lbs/in2.Type: GrantFiled: March 22, 2000Date of Patent: January 8, 2002Assignee: Cosmed Group, Inc.Inventors: Gary B.

Patent number: 6336280Abstract: A self-propelled rotary excavator having a plurality of booms forming a boom assembly attached to a chassis, with a rotary cutting device attached to the end of the boom assembly. The boom assembly positions the rotary cutting device at a desired position in regard to the chassis or moving portion of the self-propelled rotary excavator. The position of the rotary cutting device is maintainable (preferably controlled by lasers) so as to provide a ditch which has a constant grade regardless of the undulations of the land upon which the self-propelled rotary excavator traverses. An operator of the self-propelled rotary excavator can also independently control both the depth of the cut produced by the rotary cutting device and the distance in a direction perpendicular to the depth of the cut produced by the rotary cutting device.Type: GrantFiled: June 29, 2000Date of Patent: January 8, 2002Assignee: Mississippi State UniversityInventor: Norman M.

Patent number: 6331839Abstract: An easily installable signal enhancement addition for a satellite dish, and method for using an installed dish as a reference that allows installation of the enhancement without re-acquiring the satellite signal or re-aiming the dish. In one variation, the enhancement includes a reflector addition fitted with fasteners that locate the reflector against the existing dish, and use of the original feed horn, which is relocated using a support extension. This variation avoids the “shadow” of the feed horn and its support arm, and minimizes the reflective surface area at the lower end of the dish, which reduces collection of such interfering material as snow, rain, and debris. In variations using increased reflector size, the enhancement reduces loss of signal during inclement weather or in other situations in which the satellite signal is partially blocked. In one variation, the added reflector is a standard parabolic reflector superimposed over the original reflector, or replacing it on its mount.Type: GrantFiled: March 1, 2000Date of Patent: December 18, 2001Inventor: Burt Baskette Grenell

Patent number: 6322727Abstract: A kit for detecting a first substance in a sample including a stabilized 1,2-dioxetane bearing an enzyme-labile substituent, which is destabilized and caused to decompose by contacting the 1,2-dioxetane with an enzyme under conditions which cause the enzyme to cleave the enzyme-labile group from the dioxetane, thereby yielding a negatively charged oxygen anion bonded to the 1,2-dioxetane, which causes the 1,2-dioxetane to decompose without input from an external excitation energy source, the decomposition being accompanied by chemiluminescence; and a second component selected from the group consisting of a specific affinity substance (e.g., an antigen, an antibody or a nucleic acid probe) and an enzyme which destabilizes said 1,2-dioxetane.Type: GrantFiled: March 29, 2000Date of Patent: November 27, 2001Assignee: Tropix, Inc.Inventor: Irena Y. Bronstein

Patent number: 6296385Abstract: A probe for measuring the viscosity and/or temperature of high temperature liquids, such as molten metals, glass and similar materials comprises a rod which is an acoustical waveguide through which a transducer emits an ultrasonic signal through one end of the probe, and which is reflected from (a) a notch or slit or an interface between two materials of the probe and (b) from the other end of the probe which is in contact with the hot liquid or hot melt, and is detected by the same transducer at the signal emission end. To avoid the harmful effects of introducing a thermally conductive heat sink into the melt, the probe is made of relatively thermally insulative (non-heat-conductive) refractory material. The time between signal emission and reflection, and the amplitude of reflections, are compared against calibration curves to obtain temperature and viscosity values.Type: GrantFiled: May 12, 1998Date of Patent: October 2, 2001Assignee: Mississippi State UniversityInventors: Krishnan Balasubramaniam, Vimal Shah, R.

Patent number: 6280614Abstract: A water-tight fiberglass septic tank is strong enough to withstand live loads. The fiberglass septic tank is preferably designed with integral ribs to for structural strength. In one preferred embodiment, the tank is made in two unequal halves. The lower half comprises the major portion of the tank and includes a bottom, two endwalls and two sidewalls. The upper half comprises a cover. This arrangement allows the horizontal seam to be placed above the internal waterline, thereby protecting the seam from exposure to sewage. At least one of the endwalls includes a raised top portion that allows a pipe to be located near the top of the lower portion without passing through the seam between the upper and lower portions of the tank. The endwalls are also curved to allow for angled inlet and outlet pipe connections. The ribs are preferably internal and hollow. The lower portion of the tank is also preferably flat bottomed. A provision has been made for a self-locating baffle if required.Type: GrantFiled: March 2, 2000Date of Patent: August 28, 2001Assignee: Xerxes CorporationInventors: Robin Berg, Kaushik Mallick, Brian Garcia, Michael Zais
