摘要： There is provided a fluid sampling apparatus for withdrawing samples of groundwater or other fluids from a well or other monitoring site. The apparatus preferably includes pump means, packer means, conduit means and a wellhead assembly that are permanently installed at the well or monitoring site and are thereby dedicated thereto in order to avoid or minimize cross-contamination of samples from site to site. The packer is integral with the pump and isolates the groundwater below the packer in order to minimize the amount of groundwater which must be pumped in order to purge the well prior to taking an acceptable sample. The apparatus preferably also includes a removable and portable controller means adapted for easy and convenient transportation and connection to such dedicated fluid sampling components at various wells or monitoring sites.

摘要： A method for using a controller to control a fluid pump by controlling the rate at which the pump fills with fluid and subsequently discharges fluid. The pump includes a chamber for collecting fluid from within a well bore in which the pump is disposed. A user inputs a pump cycle time and a pump cycle volume to the controller. The pump cycle time input is used to determine a cycling period for the pump. The pump cycle volume is used to allot a portion of the cycling period to the refilling of the pump with fluid and the remaining portion of the cycling period to the discharging of fluid from the pump. The controller controls the pump such that the pump is vented to atmosphere during the refill portion, allowing the pump to fill with fluid, and such that pressurized fluid, such as compressed gas, is injected into the pump during the discharge cycle, causing fluid collected within the pump to be discharged. In another mode of operation, a sensor is coupled to the controller. The sensor sense when the water level in the well bore drops below a maximum desired drawdown level, and the controller adjusts the pumping rate to avoid exceeding the maximum drawdown level.

摘要： The present invention provides a method for monitoring select purge water parameters and determining when the parameters have stabilized. The method includes the steps of selecting which parameters are to be monitored and selecting the time interval between which evaluation readings are performed. The time interval may be selected in set time increments from within a predetermined time range. With the passing of each interval, the results of the evaluation readings are stored in a memory device for at least one, and more preferably a plurality, of consecutive readings. If the readings do not fall within the defined stabilization ranges for the selected parameters, the oldest scan is deleted from the memory device. The comparison of the reading results is again performed with the start of the next interval, with the new reading results being compared to the two old reading results. When the selected parameter values do fall within the defined ranges for three consecutive readings, the operator is alerted that stabilization has been obtained.

摘要： A method and apparatus for monitoring the fluid level in a well bore to limit fluid drawdown in the well bore to a maximum set level. The user first determines the static water level in the well bore by lowering a sensor into the well bore. The sensor is configured to sense when it makes contact with water, so that the user can be made aware that the sensor has reached the static water level. The user then lowers the sensor to a maximum desired drawdown level. The sensor is then set to sense when it loses contact with the water. The sensor is then monitored to determine if the fluid had has dropped below the maximum desired drawdown level, and an audible and/or visual alarm alerts the user whenever the maximum desired drawdown level is exceeded.

摘要： There is provided a dual pump floating layer recovery apparatus for pumping a floating layer of contaminant out of a well. The apparatus comprises an upper pump and a lower pump. The lower pump creates a cone of depression which increases the amount of the floating layer within the well. The upper pump pumps the contaminant from the well or cone of depression. The upper and lower pumps preferably are gas-actuated pumps. The lower pump preferably includes an automatic switching device to activate the lower pump upon sensing a predetermined amount of fluid within the pump. A gas conduit interconnects the actuation chambers on both pumps such that when the lower automatic pump is provided with pressurized gas, the upper pump is simultaneously provided with the identical pressurized gas. Upon deactivation, both pumps relieve the activation pressure through the lower pump.

摘要： A tension adjuster is mounted on and is part of an external fixation device comprising frame segments rigidly supporting fixation pins that pass through and immobilize fractured bones during rehabilitation. This tension adjuster securely attaches the fixation pins to the frame segments and adjustably applies tension along the fixation pins to more rigidly secure the fixation pins and to improve the immobilization of the fractured bones. The tension adjuster comprises a threaded slotted screw attached to the fixation pins and comprises a mounting nut having an aperture through which is drawn the threaded slotted tension screw while adjusting the tension along the fixation pins. A tapered pin extending into the aperture of the mounting nut and into a chamfered slot of the threaded slotted tension screw, guides the threaded slotted tension screw through the mounting nut during tension adjustments. A tension nut rotating upon the threaded slotted tension screw and buttressing the tension mounting nut operates by simple turning motion to draw the threaded slotted tension screw through the tension mounting nut and thereby applying tension along the fixation pins.
