  • Patent number: 5907110
    Abstract: A fluid sampling tool for sampling fluid from a container. The tool has a fluid collecting portion which is drilled into the container wall, thereby affixing it to the wall. The tool may have a fluid extracting section which withdraws fluid collected by the fluid collecting section. The fluid collecting section has a fluted shank with an end configured to drill a hole into a container wall. The shank has a threaded portion for tapping the borehole. The shank is threadably engaged to a cylindrical housing having an inner axial passageway sealed at one end by a septum. A flexible member having a cylindrical portion and a bulbous portion is provided. The housing can be slid into an inner axial passageway in the cylindrical portion and sealed to the flexible member. The bulbous portion has an outer lip defining an opening. The housing is clamped into the chuck of a drill, the lip of the bulbous section is pressed against a container wall until the shank touches the wall, and the user operates the drill.

  • Patent number: 5902940
    Abstract: A improved disposable bailer which is made of a pliant or flexible transparent tubing material for the collection of fluids and/or gases. The present invention allows sampling in minimally sized bores or wells which are not perfectly straight. Also, the invention permits sampling at the top of a fluid column or within a fluid column and permits acquisition of a vapor sample on top of the fluid column. In this embodiment, a vapor or liquid specimen may be sampled through a septum on the surface of the bailer. Also in this embodiment, fluids and gases may be collected through a flexible nozzle which acts as a valve when the collected sample constricts the nozzle opening due to the presence of the collected sample in the tubing. In another embodiment, samples are collected through the top of the tubing, allowing selective sampling within a column of fluid when the tubing is immersed. Another embodiment utilizes both the flexible nozzle and top opening to collect samples.

  • Patent number: 5895836
    Abstract: The method of the invention allows adjustment of the Greyscale of a digital print in addition to adjusting the individual colors thereof, which have a tendency to vary as the respective inks are changed, the paper or canvas stocked utilized is replaced, or the printer drifts with time. In accordance with a preferred embodiment of the method, the densitometers employed in calibrating the printer are individually adjustable to vary the Greyscale, where needed, while continuing to tailor the component colors displayed. Rather than utilizing prior art methods of only calibrating the printer, the method of the invention additionally permits the adjustment of the calibrator in maintaining proper Greyscale.

  • Patent number: 5892162
    Abstract: An apparatus and method for directing ultrasonic and magnetostrictively generated mechanical waves from an exterior point to an interior point within a small diameter tube, pipe, or cylindrical structure. The present invention incorporates an external mechanism for generating waves in a cylindrical waveguide tube gun of a size small enough for insertion into the target tube and configured so as to maintain mechanical contact with an inside diameter of the target tube. Standard ultrasonic wave generating devices or magnetostrictive/mechanical wave generating coils are positioned on the waveguide external to the target tube and generate appropriate mechanical waves through the waveguide to a point interior to the target tube. A mechanical interface between the waveguide and the inside diameter surface of the tube is positioned and provided at a point within the target tube to transfer both the interrogating waves and the received return signal waves between the target tube and the waveguide.
