  • Patent number: 11921107
    Abstract: Disclosed is an assay device which comprises a liquid sample addition zone, a reagent zone, a detection zone, and a wicking zone, all defining a fluid flow path. The device further comprises a reagent addition zone along and in fluid communication with the fluid flow path downstream of the sample addition zone and upstream of the detection zone. An interrupting wash is added at this reagent addition zone in accordance with the method of the subject invention to control sample volume. The interrupting wash fluid is added at a predetermined fill volume on the chip device and also serves to wash the detection channel and fill the remaining chip volume.

  • Patent number: 5792384
    Abstract: A buffer solution comprising one or more metal salts, preferably monobasic potassium phosphate and/or monosodium phosphate, dissolved in water creates a rinse having a pH near that of human skin. The buffer solution in various concentrations and compositions is adapted for routine use by professional and casual users of cement to rinse their skin and tools, as a spray-on application for skin and clothes, and as a pre-wash for laundry. The buffer solution may include other metal salts, preferably manganese sulfate, further to reduce hexavalent chromium carried into the rinse from cement. A pH color indicator such as phenolphthalein also may be included to signal when the buffer solution becomes ineffective from prolonged use.

  • Patent number: 5388885
    Abstract: A vehicle body structure of a vehicle has a pair of body side frame sub-assemblies running longitudinally on the vehicle and an underbody sub-assembly extending transversely across the vehicle. Each of the body side frame assemblies has a body side outer panel having a lower horizontal flange extending longitudinally and projecting outboard, and a forward vertical flange projecting outboard. A longitudinally extending rocker inner frame of the body side frame assembly has an inboard vertical wall spaced inboard from the body side outer panel and a lower horizontal wall projecting outboard having an extreme outboard portion underlying the lower horizontal flange of the body side outer panel. The underbody sub-assembly has a generally planar floor pan having a pair of longitudinal edges and a horizontal surface adjacent to each of the longitudinal edges underlying and engaging the lower horizontal wall of the rocker inner frame of one of the body side frame sub-assemblies.

  • Patent number: 5282726
    Abstract: Apparatus and method for increasing the capacity of a gas compressor. The apparatus comprises a supercharger for compressing a gas flow and an evaporative cooler for cooling and ducting the supercharged gas flow to the gas compressor. The cooler comprises a section of pipe connecting the supercharger and the compressor. Mounted on the wall of the pipe are nozzles oriented upstream to atomize water into droplets of mean diameter ranging from about 4 to about 12 microns. The pipe is sized to provide a residence time of from about 0.1 to about 0.5 seconds for the droplets in the gas flow.

  • Patent number: 5095655
    Abstract: A vehicle door assembly has a pair of spaced guide channels carried below its belt line which slidably receives pin guides secured to the sides of the lower end portion of the window for guiding the movement of a window between its open and closed positions. The window is bent along a horizontal line so that its exterior surface will be substantially flush with an exterior surface of the door assembly when in its closed position. The door assembly also includes a door frame means which permits lateral movement of the window as it is moved between its open and closed positions and a seal means carried by the door frame which engages the window along its interior sides to bias the same outwardly toward an outer flange on the door frame.

  • Patent number: 4896442
    Abstract: A trencher comprising a digger located adjacent the rearward wheels, which pair of wheels are driven hydraulically and which have an open area between them into which the digger may be partially positioned. The forward wheels of the trencher are steerable by use of a self-locking angular adjustment mechanism. A hydraulic circuit which includes a pressure relief valve provides substantially constant pressure on the chain of the digger. A locking mechanism is provided for the forward wheels when initiating the cutting action of the digger.

  • Patent number: 4695185
    Abstract: This disclosure relates to an applicator for placing a sealant into a groove, and comprises a member having a lower side, the lower side being adapted to extend into the groove. The lower side has an arcuate shape and a sealant passage extends through the member and includes an outlet opening in the lower side. The arcuate lower side is adapted to extend partially into said groove and engage the upper corners of the groove during use. The applicator further includes a limiter attached to the member, the limiter extending laterally of the lower side and over the upper corners of the groove.

  • Patent number: 4561211
    Abstract: The disclosure relates to a vehicle door and window assembly in which the door has a pair of spaced, arcuate sheet metal guide rails and the window adjacent its side edges is secured to a pair of plastic guides which are slidable on the rails for movement through a path of a given radius and with the guides maintaining the windows substantially flush with the adjacent side door structure. The plastic guides have a transverse dimension, as measured between the rails and the outer window surface, which progressively increases proceeding from their upper ends toward their lower ends so that the window has a radius which is greater than the radius of its path of movement whereby the window is moved away from its outer belt line seal when lowered into the door and whereby the window moves both upwardly and outwardly as it is being raised so that it is also substantially flush with the outer belt line of the door when in its closed position.
