Abstract: The embodied invention is an enhanced rotary brush tool that provides important cleaning on porcelain surfaces that are stained by hard water deposits. The brush tool incorporates an outer holder that includes a motor connecting end, a tapered shaft, an outer cup and shroud. A fill epoxy bonds the outer holder together with an internal strengthening rod and an abrasive pad. The overall assembly provides significant compressive strength to allow an individual to utilize pressure when scrubbing off the water hardness buildup.

Abstract: The invention provides novel compositions of matter for the production of ethanol from carbon dioxide and water. Particularly, the invention provides photoautotrophic organisms having a first and second genetic modification, wherein the first genetic modification improves the ethanol production from organisms having the second genetic modification.

Abstract: The invention provides genetically modified photoautotrophic ethanol producing host cells. Ethanol production is controlled by an inducible promoter. Promoters utilized may be endogenous or heterologous, and genetic modification may be obtained by extrachromosomal means or chromosomal insertion.

Abstract: Myocardial revascularization is performed by an apparatus and method which forms channels in the myocardium from inside the ventricular cavity without penetrating the full thickness of the ventricular wall. A catheter has a fiber optic connected at its handling end to a laser, and terminates at the insertable end of the catheter. A servomotor controls the advancing of the fiber to stop positions relative to the catheter. At each stop position another channel is created. An aiming beam aids in directing the channel forming fiber end to different desired channel positions.

Abstract: A sound abatement method includes applying a sound abating material to at least one area of at least one component of the moving trolley. A sound abatement conveyor trolley includes a trolley body having at least one wheel for traveling in a track and one or more component cooperatively associated with the trolley body, which the components each include a sound abating material applied to the area for sound abatement. An element used in a conveyor trolley includes at least one area and a sound abating material applied to the area for sound abatement.

Abstract: A device for keeping row crop spraying booms, cultivating tools and other agricultural equipment in the correct position relative to rows of plants, where infra-red beams are used to determine the position of the booms or tools in relation to the rows, and activates rams or other actuators to move the booms or tools to the desired relationship with the rows when preset allowable deviation is exceeded.

Abstract: An apparatus is provided for drilling concurrently a plurality of wells within a laterally confined area. The confines of the drilling apparatus employ a structure having vertically extending walls rising from a drilling floor. A plurality of wells are drilled, each employing a separate rotary drilling table and a separate draw work assembly mounted in vertical displacement from the drilling table associated there with. Preferably, the individual draw work assemblies associated with separate one of the rotary drilling tables are utilized only to feed drilling pipe assemblies into the well and to aid in the actual drilling operation. To withdraw drilling pipe assemblies, a master draw works is provided and is mounted vertically above the draw work assemblies associated with particular rotary drilling tables.
