  • Patent number: 5138890
    Abstract: Both apparatus and the method is directed to a sampler array carrying a plurality of samplers in which the array has a trip assembly with a plurality of lanyard release pins. One moving member in the assembly contains a pivotal cam which is spring loaded in order to pass a plurality of lanyard release pins in one direction, but to move in the opposite direction and depress the lanyard release pin thereby releasing the lanyard to a preselected sampler for purposes of closing the same and entrapping a sample by the exact sampler desired by the operator at the surface. The method then contemplates counting the degrees of movement of a moving trip wheel having a release cam in one direction in which each sampler lanyard release pin is bypassed, and thereafter reversing the same having the lanyard release pin which is desired to be activated confronts the angled under surface of the lanyard release cam which, when reversed, will depress the lanyard release pin and release the lanyard to close the sampler.

  • Patent number: 5138868
    Abstract: A method of calibrating pipette position in an automated assay instrument employing a conveyor for holding assay cartridges and a transport for transporting a pipette between various locations is accomplished by alignment of a pipette stem with targets located at various locations within the system. Two targets are located on a tray having a plurality of reservoirs for holding liquid, and one target is located on a dummy cartridge carried by the conveyor. An indicator having a spring-loaded tab is used in conjunction with a pipette stem modified by inclusion of a circumferential slot for receiving the spring loaded tab. The stem is inserted into the indicator and locked therein, with limited sliding being provided by movement of the tab within confines of the slot. Alignment marks are provided on both the stem and the indicator to permit visual alignment of the stem relative to a target upon abutment of the indicator with the target.

  • Patent number: 5138891
    Abstract: A system for a gauge well in a liquid storage tank with a floating roof including a floatable container located inside the gauge well and having a flexible laterally or radially serrated flange extending outward from the float and in contact with the inside of the well pipe to prevent vapor from the liquid stock from rising in the pipe. There may be a pair of such flexible flanges vertically spaced apart with the lower seal being just above the level of the liquid stock in the well pipe. A tape is attached at its lower end to a weight in the well pipe below the float and its upper end is connected to a winch outwardly of the upper end of the well pipe. A vertical passageway through the float is provided for the tape to pass freely therethrough and the float is freely slidable on the tape. The container includes a closed opening which is selectively opened to fill with the liquid stock at any selected level in the tank.

  • Patent number: 5136886
    Abstract: A lightfastness testing chamber comprises an enclosure for samples being tested and at least one, and preferably a plurality of, lamps for irradiating samples in the enclosure. A monitor of the light intensity from each lamp present is provided. By this invention the monitor may comprise a light transmission rod, and preferably one such rod for each of the lamps, having one end positioned adjacent the lamp and another end in communication with light intensity measuring apparatus positioned more remotely from the lamp than the one end. The light transmission rod is preferably positioned on a side of the lamp that is substantially opposed to portions of the lamp that directly irradiate samples in the enclosure. Also, the samples may be moved by an elevatable platform or the like toward and away from the irradiating lamp or lamps to vary as desired the intensity of irradiation applied to the samples.

  • Patent number: 5133210
    Abstract: Disclosed is a method and apparatus of indentation testing of variable types of specimens which includes mounting an indenter member onto a thermally expandable member, mounting the specimen to be tested on a pedestal, loading the specimen with the indenter member by thermally expanding the thermally expandable member and measuring applied force to and displacement of the specimen so as to determine the hardness or other material properties of the specimen. The indenter member is thermally insulated from the thermally expandable member prior to thermally expanding the thermally expandable member. The thermal expansion driven indentation system in the present invention allows for controlled application of precise and continuous reproducible loads to produce stress-strain plots. Continuous indentation testing with this system has yielded results which correlate well to Rockwell fixed load hardness tests on standard test blocks.

  • Patent number: 5131283
    Abstract: A tool for piercing an electric distribution transformer tank for obtaining a sample of oil therefrom to be tested for PCB contamination is disclosed. The tool includes a threaded body with a wrenchable fitting on one end and a tank punch pin on the other and is adapted for threadable insertion into a threaded hollow shaft of a ground lug nut attached to the tank. The pin is advanced in the lug nut shaft to pierce the tank by wrenchably rotating the fitting. Hollow shafts formed through the pin, punch body and fitting provide a path for the flow of oil from a space in the lug nut shaft between the hole in the tank and the end of the punch body to a syringe which contains a threaded tip inserted into a threaded shaft in the fitting when suction is drawn by the syringe on the shafts after the hole is punched and the pin is backed slightly out of the hole. A threaded nut seals the threaded shaft in the fitting after the filled syringe is removed from the tool to prevent oil leakage.

  • Patent number: 5129268
    Abstract: A method of measuring an average particle size of granules. The method computes the average particle size on the basis of an n-order moment M.sub.n of an image of granules accumulated in a pile or of the image subjected to binarization or floating binarization. The method is capable of highly accurate and stable measurement on granules having many irregularities in the surface thereof and accumulated in a pile. The method can be used to continuously measure in real time the particle size of granules in a rotary tray of a rotary tray-type rolling granulating machine thereby adjusting the feed rate of a liquid binder to automatically control the particle size.

  • Patent number: 5127276
    Abstract: An inspection drain plug that is removably connected to an aperture in a fluid reservoir. The drain plug comprises an outer hollow body having an open first end and an open second end, the first end being removably connected in a fluid flow relationship to the aperture of the fluid reservoir. A valve mechanism is connected to the outer body, such that the valve mechanism may be selectively operated between an open and closed position, so that the first end of the outer body is closed when the valve is in the closed position. The drain plug also comprises a biasing mechanism, whereby the valve is biased toward the closed position. The first end of an inner hollow body, having an open first end and a closed second end, is removably inserted within the second end of the outer body. Upon insertion of the inner body within the outer body the closed second end of the inner body operatively engages the valve, thereby selectively moving the valve between the closed position and the open position.

  • Patent number: 5119684
    Abstract: An apparatus for determining the collectability of dust particles is disclosed herein. The concept of collectability and collectivity are employed to establish fundamental equations which are solved by the use of data obtained by passing a dust laden gas through a sampling train having a plurality of impingers. The weight of material collected in each separate impinger is determined and using these individual weights a mathematical matrix is set up from which the collectability of the dust particles is obtained. The collectability of a given dust particle is defined as its impinger efficiency when the impinger is operated in strict accordance with design specifications. Collectivity is defined as the collectability distribution of a mixture of dust particles having different collectabilities.
