Abstract: A control system for a mining machine which moves in passes across a seam to be mined using absolute coordinates is disclosed. The machine is carried on rail and co-ordinates of the rail are measured along the length of rail. The rail is then moved to a new position for a next pass, and the distance of moving is determined from the co-ordinates previously measured. By knowing the co-ordinates, the rail can be moved to assume a desired profile, so that a desired profile of the seam can be achieved on the next pass. Co-ordinates of the up and down movement of a shearing head can also be measured and stored with the co-ordinates along the rail to provide a profile of the seam being cut, and so that on a next pass the intended position of the shearing head can be predicted and moved accordingly.

Abstract: A mining machine (7) is provided which moves from side-to-side in sequential passes across a seam of material to be mined. The machine (7) is carried on rail means (19) and co-ordinate positions of the rail means (19) are measured at locations along the length of the rail means. A trailing part of the rail means (19) is then moved by rail moving means (25) to a new position for a next pass, and the distance of moving is determined from the co-ordinates of the positions previously measured. By knowing the co-ordinates of the positions, the rail means (19) can be moved to assume a desired profile, so that a desired profile of the face of the seam can be achieved on the next pass of the machine (7). Desirably the profile is a straight line.

Abstract: A method, system, and computer-readable medium controls one or more applications in a graphical user interface type operating system. All events that occur through the graphical user interface are recorded and a script file is generated comprising instructions based on the recorded events. A compiler compiles the script file into a binary language file; and an event player executes the binary language file to control the one or more computer applications according to the instructions. In a preferred embodiment, all mouse and keyboard events that occur through a graphical user interface in a Windows, MacOS, or X-windows based operating system are recorded. The above events are created directly or indirectly by a user of the graphical user interface.

Abstract: A filter assembly, particularly for use with a plastic bottle having an open neck with an inside diameter of about 50 mm or less (e.g. about 25 mm), includes a tube of filtering material connected to one surface of a cap while a valve extends from an opposite surface of the cap. The tube is preferably of filtering material such as activated carbon with plastic binder, having a substantially continuous liquid-porous sidewall, a hollow interior, a first closed end, and a second open end. The tube is operatively connected to the cap second surface at the tube second open end by sonic welding, a mechanical connection, or adhesively. The cap has a fitting portion for cooperating with the bottle neck, such as internal screw threads or a snap portion. The valve may be a reciprocating valve, a baby bottle nipple, or a spray device. A biocidal medium may be disposed within the hollow interior of the filter tube, and the tube may be wrapped with a filter material having a pore size of about 1-4 microns.

Abstract: Herein is disclosed a continuous process for manufacturing purified silver nitrate solutions comprising the steps of:a) transferring a crude silver nitrate solution, together with a slurry comprising silver oxide, to a multistage agitated reactor, thereby forming a mixture;b) maintaining a continuous weight percent undissolved solids inside the reactor such that silver oxide is 10 to 80 weight percent of said undissolved solids;c) transporting the first mixture through the reactor over a period of 15 minutes to 3 hours to form a reaction product; andd) filtering the reaction products through a continuous filter to form a silver nitrate filtrate.

Abstract: Today when most passenger cars are fabricated without frames, many people are using vans and sports utility vehicles to pull trailers. These vehicles have improved efficiency and apparent power when equipped with a wind deflector. A wind deflector for such vehicles is disclosed which comprises a top member which is mounted on the rear portion of the vehicle and two side members having front side portions which extend downwardly from the top member along the sides of the vehicle. All said members curve outwardly from the front side portions thereof away from the vehicle. All members are molded from semi rigid plastic and have spaced braces on the rear interior side portion thereof. The top and side members are matably fitted together and releasably held together by buckles. The wind deflector is removably mounted on the vehicle using hook bolts, straps and bars which are fastened to the frame beneath the vehicle.

Abstract: A liquid treatment mechanism may easily be snapped on, or otherwise attached, to the neck of the single orifice bottle, such as a standard five gallon water bottle. An end cap is connected to a first tube of the liquid treatment mechanism, the liquid treatment element (such as activated carbon) disposed in the first tube and extending from the second end of the first tube to a termination position near, but spaced from, the first end of the first tube. A liquid inlet allows for the passage of liquid from exteriorly of the first tube into contact with the liquid treatment element. A dispensing tube (which may include a cyst or other particle filter) is disposed adjacent the first end of the first tube and extends from the liquid treatment element. An air inlet (e.g., a free about 0.02-0.1 inch diameter hole) is disposed in the first tube near its first end and exteriorly of the dispensing tube. A sheath of porous material may wrap the activated carbon, which may be either in hollow tubular or block form.
