Abstract: A novel process for the purification of crude aromatic carboxylic acids, such as, for example, terephthalic acid, orthophthalic acid, trimesic acid, isophthalic acid, 2,6-naphthalenedicarboxylic acid and pyromellitic acid, which are obtained by oxidising the corresponding aromatic precursors is described; the process is based on the subsequent oxidation in heterogeneous phase of the crude product in aqueous solution.

Abstract: A description is given here of a novel process for the production of monocarboxylic and polycarboxylic aromatic acids by the catalytic oxidation in homogeneous phase of aromatic compounds carrying at least one oxidizable substituent group attached directly to the carbon atom of the corresponding aromatic nucleus. The novel process according to the present invention comprises the steps of: a) catalytically oxidizing the corresponding aromatic precursors in liquid phase in the presence of gaseous oxygen; b) filtering the end product; c) recycling into the oxidation reactor at least part of the mother liquors resulting from the filtration stage, and is characterized by the fact that said steps from (a) to (c) are carried out in a closed and continuous cycle operating substantially under the same pressure and temperature conditions, preferably at 2-10 barg and 100-140° C.

Abstract: A fuel expansion system or carburetor for internal combustion engines utilizing the bubbling of air through use of a number of bubble tubes through a supply of liquid fuel. The resulting atomized, vaporized and expanded fuel is then mixed with air and fed into the engine for combustion.

Abstract: The present invention is a method of making a building wall panel or building wall panel system. The building wall panels are made by taking a standard panel of metal roof decking having alternating ridges and channels and attaching a length of board stock, such as a concrete board. These panels are then able to be attached to a steel frame or other type building shell.

Abstract: A feminine hygiene disposal unit for sanitary receipt and disposal of used sanitary products. The unit has a disposal bag dispenser, at least one disposal bag, a receptacle, and a liner for the receptacle. This liner having a lid flap having an opening therethrough, this lid flap being supported through use of a pair of sandwiching flanges for sandwiching the lid flap in a generally horizontal orientation.

Abstract: An attachment for fastening a brush to a shoe. The attachment having a first (horizontal) flange extending to a second (vertical) flange. The first flange attaching to the sole of the shoe, with the second flange attaching to a wiping element such as a brush. The attachment could alternatively be provided with a disk-like single flange having threading allowing the attachment to be screwed into a standard golf shoe threaded spike hole.

Abstract: An improved vacuum motor air intake for use on vacuum motor device with a funnel shaped shroud enclosing a portion of the vacuum motor housing adjacent a fan assembly. Combined with the funnel shaped shroud, a conical air deflection body directs air entering the motor in a laminar flow pattern.

Abstract: An improved cutter blade assembly for cutting vegetable products such as potatoes. The cutter blade assembly utilizes a number of cutter blades that transverse an axial bore through which products to be cut are fed. These blades are locked within the assembly by an attachment system that partially deforms the blade to hold the blade in place. This improved attachment connection system serves to hold the blade in a position having higher tension and thereby reduces wear, chatter, and feathering.

Abstract: The invention is a double duct changeover HVAC system, which uses two conditioned air sources to deliver air into two main duct systems. The two main duct systems are routed toward the exterior exposures of a building, and converge into a single duct which is routed to heating and cooling zones. Exterior exposure dampers control the mix of air so that the correct air temperature is sent to each exterior exposure. A damper at each heating and cooling zone controls the air flow into each heating and cooling zone, and VAV logic is used to deliver the correct air temperature and air flow to each heating and cooling zone of a building.

Abstract: A portable endothermic caulk warmer for warming at least one tube of endothermic caulk. This caulk warmer having an insulated housing, at least one AC heating pad, a AC/DC power inverter and a DC rechargeable battery.

Abstract: An air compressor for use with direct source current sources such as the typical cigarette lighter found in most motor vehicles. The device is made up of an electrically powered air compressor which is controllable by a removable programmable controller. This removable programmable controller is configured to be removable from the compressor to measure an amount of air pressure within an item, and to be programmed and placed upon the compressor to activate the compressor to deliver a desired amount of air to the item being inflated, and to deactivate the compressor when a desired amount of air pressure has been reached within the device.

Abstract: A tape measure that incorporates a marking device for allowing an individual to measure and mark a wide variety of materials in a more efficient and economical manner, and for measuring and marking the beginning point of reference and the measured position point simultaneously. The tape measure has a housing, a coiled measuring tape, a tape tip, and a marker having a marking wheel mounted on an axle.

Abstract: A positioned sensing device measures and/or calculates the lateral position and movement of a saw blade. These measured and calculated values are used to automatically alter the work-feed rate and/or saw blade rim speed either up or down as sawing conditions change within the work piece or between different work pieces.

Abstract: A heat transfer array is presented which includes one or more pouch flexors that press down on a fluid product containing pouch and facilitate heat exchange by mixing the pouch contents while the exterior of the pouch is contacted by a heat exchange medium. The pouch flexors are arranged in an array of three wheels, and the pouches are subjected to a number of wheel arrays in order to exchange heat from the pouch contents. The pouch flexors are stationary and a conveyor belt moves the pouch product under the wheel arrays.

Abstract: An equine dental speculum maintenance system utilizing rotatable and replaceable wear components in order to extend the useful life of an equine dental speculum. Both the toothed rack and the pawl are rotatable and replaceable.

Abstract: A water detection device and alarm. The water detection device includes protruding electrodes above and below the device which detect water on a surface below the device, and water dripping from above the device. The electrodes are rod-shaped, and can penetrate a material to detect moisture in subsurface regions of the material. The device has a lifting ring, and may be placed in difficult to access positions by means of the lifting ring. A deflector cone directs water from above the device into a splash ring. When water or moisture completes a circuit between two of the electrodes, an alarm enunciator signals the presence of water.

Abstract: An apparatus for cutting optimally sized fruit and vegetable pieces comprised of a dump chute, a trough, a conveyor, a drive means, at least one sensor, a programmable logic controller (PLC), and a cutter assembly. The apparatus is configured to receive materials from a source, load these materials onto a conveyor move these items by means of the conveyor to a cutting portion where the materials are cut into appropriate sized pieces, as determined by a programmed logic sensor based upon the input from a plurality of sensors and pre-selected criteria from a user.
