Publication number: 20140295403Abstract: This invention relates to a method and apparatus for detecting a biological molecule associated with enzyme activity in a sample. The invention is applicable to detecting a microorganism associated with an enzyme in a sample such as water, food, soil, or a biological sample. According to a preferred embodiment of the method of the invention, a sample containing an enzyme of interest or a microorganism associated with the enzyme is combined with a suitable substrate, and a fluorescent product of the enzyme-substrate reaction is selectively detected. The fluorescent product is detected with a partitioning element or optical probe/partitioning element of the invention. In one embodiment the partitioning element provides for partitioning of only the fluorescent product molecule into the probe. The invention also provides an automated system for monitoring for biological contamination of water or other samples.Type: ApplicationFiled: November 18, 2013Publication date: October 2, 2014Applicant: QUEEN'S UNIVERSITY AT KINGSTONInventors: R.

Patent number: 6224164Abstract: A mining machine that has a chassis that defines an operator area thereon and has a mining assembly attached thereto. A vertically extending shield assembly is supported on the chassis to prevent material that is dislodged during the mining process from inadvertently entering the operator area. The shield assembly may be selectively vertically extendable and may be equipped with a ventilation duct assembly to withdraw dust and gases away from the operator area. The mining machine may be equipped with a mining assembly that extends the entire width of the chassis and that can be advanced forwardly of the chassis and swung down across the seam face during mining. The present invention may also be equipped with a quick disconnect assembly for detachably mounting the mining assembly or other mining implement to the mining machine.Type: GrantFiled: February 12, 1999Date of Patent: May 1, 2001Assignee: Joy MM Delaware, Inc.Inventors: Kevin R. Hall, Gregory S. Wilson, John R. Frederick

Patent number: 5366068Abstract: Disclosed is a conveyor belt/cutting head advancement mechanism (10). Mechanism (10) comprises a conveyor belt support structure (11) connected at one end to a conveyor belt gathering structure (12). The conveyor belt support structure (11) is typically interconnected at its forward end to a self advancing conveyor return end (not shown). Material removed from a mine face by the cutting implement is delivered to a conveyor belt supported by the support structure (11). Structure (11) comprises a plurality of structural elements (18) pivotally interconnected in a scissor-like configuration. The mid points of elements (18) are pivotally interconnected at a point coinciding with the mounting location of a conveyor belt return roller (16). At the upper pivotally interconnected extremities of elements (18), the conveyor belt advancing rollers are supported. Mounted at a location nearby the lower ends of elements (18) are ground engaging wheels (17).Type: GrantFiled: May 20, 1993Date of Patent: November 22, 1994Assignee: Australian Longwall Pty. LimitedInventors: Kevin R. Hall, Gordon Wilkinson

Patent number: 5307917Abstract: Disclosed is an extendible conveyor structure (10). Structure (10) comprises a main frame (11) supported above a ground surface by way of wheels (20). Main frame (11) comprises a number of vertical members (22) and cross-members (18) extending therebetween. Main frame (11) further comprises a number of longitudinal members (23). Either fixed to main frame (11) or rollably supported thereby is a sub-frame (14) to support a conveyor belt (16). Rollably supported to sub-frame (14) is a pair of movable sub-frames (12, 13). The conveyor belt (16) spans all three sub-frames (12, 13 and 14) and is supported by rollers (15) or alternatively by troughing plates or a combination of both. The respective sub-frames (12, 13 and 14) may be manually or automatically extended between a loading zone and a discharge zone as required.Type: GrantFiled: November 13, 1992Date of Patent: May 3, 1994Assignee: MECO Australia Pty LimitedInventor: Kevin R.
