Title: Improved process for reducing levels of microorganisms in pumpable food products using a high pulsed voltage system
Inventor: DUNN JOSEPH E
IPC: A23L3/18
Filed: 1996-03-06
Abstract: The present invention is directed to methods and apparatuses for preserving fluid foodstuffs. More particularly, it is directed to methods and apparatuses for extending the shelf life of perishable fluid foodstuffs such as dairy products, fruit juices and liquid egg products, which contain significant levels of microorganisms. The improved methods and apparatuses incorporate a plurality of electric field treatment zones (106) with cooling units (108) between each pair of treatment zones in order to maintain the temperature of the pumpable foodstuff at a level at which microorganisms are killed in sufficient numbers and at which changes in the flavor, appearance, odor, or functionality of the foodstuff remain within acceptable ranges. For a comparable microorganism kill, foodstuffs prepared by the present process have significantly higher quality than foodstuffs prepared with standard thermal processes (e.g., ultra-high temperature pasteurization).

Filed: 1998-06-19
Abstract: A process and apparatus are described for producing higher hydrocarbons from lower hydrocarbons, e.g. by gas phase electrocatalytic polymerization of methane.  This is done using an electrolysis cell having an anode chamber on one side of a solid electrolyte and a cathode chamber on the other side of the solid electrolyte.  According to this process, methane-containing gas is passed through the anode chamber to contact a catalytic anode which is connected to one side of the solid electrolyte, this solid electrolyte comprising a solid proton conducting membrane.  An inert gas or oxygen is passed through the cathode chamber to contact a catalytic cathode which is connected to the other side of the proton conducting membrane. The membrane is designed so that H+ is capable of passing through the membrane from the anode chamber to the cathode chamber.  As a consequence, C-2 and higher hydrocarbons are formed in the anode chamber and hydrogen or water is formed in the cathode chamber.

Inventor: HODSON SIMON K
IPC: B29C48/07
Filed: 1997-04-09
Abstract: Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler.  Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, a cellulosic ether, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties.  The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the cellulosic ether to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation. The starch and cellulosic ether form the binding matrix of the sheets with the fibers and optional inorganic filler dispersed throughout the binding matrix. The starch-bound sheets can be cut, rolled, pressed, scored, perforated, folded, and glued to fashion articles from the sheets much like paper or paperboard. The sheets are particularly useful in the mass production of containers, such as food and beverage containers.

IPC: B60F3/00
Filed: 1998-10-26
Abstract: As an amphibious pontoon craft it is used for but not limited to land or water transport. The construction incorporates pontoons designed for maximum stability and load carrying capacity. The craft contains separate watertight compartments that make up the pontoons and may be accessible for storage purposes when fully waterproof hatches are installed. These compartments may be as few or as many as desired. At a particular dimension the pontoons may be cross-sectioned making room for a non-watertight compartment or wheel-well where a wheel assembly for land transport purposes is housed. Accessory mounting pockets may be incorporated into the top or side area of the pontoons where items may be inserted or mounted for any given reason. The portion of the craft making up the main deck may also be constructed as a watertight compartment or filled with flotation foam and semi-sealed, making it a flotation chamber. The bow of the craft incorporates a removable watertight gate, which can be lowered or raised acting as a ramp to provide access to the main deck. Incorporated into the bow sections of the pontoons, are built in lights which are wired or plugged into the tow vehicle for towing purposes. When being towed, the ground clearance of the craft can be adjusted at will by means of hydraulic, electric, pneumatic or manual power assistance etc, to accommodate the trailer hitch height of the tow vehicle by making changes to the adjustable axle, suspension or wheel. The stern section of the craft is designed in such a way that it not only ties together the aft section, but disperses load throughout the entire craft applied to it by the tow bar or propulsion devices. A removable tow bar is incorporated into the stern of the craft; it is inserted into a receiver built therein. When the craft is launched for use as water transport, the wiring for the lights is disconnected, the craft is disconnected from the tow vehicle, the retaining pin inserted through the receiver and tow bar located at the aft end of the main deck is removed and then the tow bar is removed. The wheels may be removed or retracted into the non-watertight compartment or wheel-well in the pontoons. If the wheel assembly or assemblies are of a retractable design, they may be retracted through any desired height to a maximum by means of hydraulic, electrical, pneumatic, or manual power assistance etc, therefore reducing drag in the water when the craft is being used as water transportation. The craft may be designed to use any means of propulsion when being used for water transport.

Title: Enhanced transcutaneous recharging system for battery powered implantable medical device
Inventor: WANG XINTAO
IPC: H02J17/00
Filed: 1997-09-17
Abstract: An improved transcutaneous energy transmission device is disclosed for charging rechargeable batteries in an implantable medical device and to minimize peak temperature rises in the implantable device. A current with a sinusoidal waveform is applied to a resonant circuit comprising a primary coil and a capacitor. Current is induced in a secondary coil attached to the implantable medical device. Two solid state switches are used to generate the sinusoidal waveform by alternately switching on and off input voltage to the resonant circuit. The present invention charges the batteries using a charging protocol that either reduces instantaneous charging current or duty cycle of a fixed charging current as the charge level in the battery increases. Peak temperature rises are less while delivering comparable electrical charge to the battery than for prior charging systems. A controller preferably is constructed as a pulse width modulation device with enable and reference voltage features to effectuate variable duty cycle control of the current level applied to the primary coil. An alignment indicator also is provided to insure proper alignment between the energy transmission device and the implantable medical device. The implantable device maximizes transcutaneous energy transmission at different current levels by placing different capacitors into the circuit depending on the magnitude of charging current.  Peak temperature rises are reduced while delivering comparable electrical energy charge to the battery than for prior charging systems.
