Abstract: A device designed for releasing air from the bladder of a fish brought up from depth. Depth is defined as water exceeding 33 feet deep. This device releases air from the bladder of a fish brought up from depth by puncturing the swim bladder of said fish, and consisting of an elongated hollow tubular cannula having an axially extending lumen therethrough, with a means for producing an audible, visible, mechanical or electrical alert signal activated by the movement of air.

Abstract: Method for detecting total bilirubin in urine using a chemical detection means with an indicator that will produce a detectable quantitative response in the presence of bilirubin in urine on an automated analyzer.

Abstract: Aliquot of a urine sample is placed in a first automated analyzer sampling cup and a known standard is placed in a second cup. The urine sample and standard are transferred to separate cuvettes and at least one reagent composition in an aqueous medium is injected into the cuvette. The reagent composition contains a compound to remove substances in the urine interfering with a calorimetric reaction, a compound to convert B-hydroxybutyric acid in the urine to acetoacetic acid in the presence of nicotinamide adenine dinucleotide and reading at a specified wavelength to determine quantitatively the total ketone bodies in the patient's urine.

Abstract: Method for detecting casts in urine by measuring Tamm-Horsfall protein by solid and liquid phase reagents including a method for manufacturing a enzyme specific for Tamm-Horsfall protein which produces a detectable response in the presence of casts in urine.

Abstract: Detecting white blood cells in an aliquot of urine by placing the aliquot of urine in an automated analyzer sampling cup, transferring the urine to a cuvette and injecting at least one reagent composition. The reagent composition contains a buffer, an activator such as benzalkonium chloride, an indicator and at least one substance to remove substances in the urine that cause interference with colorimetric photometry. The aliquot of urine is read in accordance with a preprogrammed code at a monochromatically specified wavelength to compare absorbance of the patient's urine with a known standard containing a known concentration of white blood cells.

Abstract: Placing an aliquot of a urine sample in an automated analyzer first sampling cup, and a standard containing a known quantity of nitrite in a second cup. Injecting known specified amounts of each sample from these cups into discrete cuvettes in the autoanalyzer, injecting at least one reagent composition in an aqueous medium containing a buffer, a compound to remove substances in the urine interfering with a colorimetric reaction, oxidized glutathione, and B-nicotinamide adenine dinucleotide phosphate or nicotinamide adenine dinucleotide and reading at a preprogrammed code in an automated analyzer at a preprogrammed wavelength to compare the patient's urine with the standard to determine quantitatively the presence of bacterial nitrite in the patient's urine.

Abstract: Method of detecting urobilinogen in urine using a chemical detection means with an indicator that will produce a detectable quantitative response in the presence of, or lack of urobilinogen in urine on an automated analyzer.

Abstract: Detecting red blood cells in a patient's urine by placing an aliquot of the urine in an automated analyzer sampling cup. The urine is transferred to a cuvette mounted within the automated analyzer and one or more reagent compositions in an aqueous medium is injected into the cuvette. The reagent contains a buffer to adjust pH, chemicals to remove substances in the urine that interfere with colorimetric photometry, a compound to lyse the red blood cells in the urine, a substrate to react with the hemoglobin, a color indicator and a surfactant to improve fluid mechanics. The sample is read against a standard using a pre-programmed monochromatically specified wavelength to determine the presence or absence of blood cells in the patient's urine.

Abstract: A scuba diver's toxic gas detector, in particular carbon monoxide detector, for use with conventional diving equipment and/or dive equipment filling systems, having a body portion (34) and a detector portion (32). The body portion (34) includes a first opening (42) therethrough communication at opposite ends thereof with connections for a first hose (14) from an air tank and a second hose(16) from a buoyancy vest (12). The body portion (34) includes another opening (50) in fluid communication with the first opening in which is positioned a guide element (68). A movable stem element (75) is positioned within said guide element (68). A bore (64) extends between the second opening (50) and the detector portion (32). A button (80) is connected to the stem element (75) and is biased in one position by a spring (82).

Abstract: A method that provides techniques for determination of urinary constituents (Blood (Red Blood Cells/Hemoglobin), Leukocytes, pH, Specific Gravity, Bacterial Reductase/Nitrite/Indole activity, Total Ketone Bodies, Protein, and Glucose) at low chemically significant levels with a carrier independent reagent system that can be placed on a high throughput autoanalyzers. Thus, giving the analyst the ability to run multiple urinary assays on a single sample of urine simultaneously with the ability to compare to reference standards on the same run. This system is designed to neutralize urinary interfering substances. This method is fast, efficient, an adaptable to many of the currently available discrete and continuous flow automated analyzers, effective at sample to reagent ratios of 1 to 13 or more. This method is applicable to samples with high turbidity, high ionic strength, high color content, wide pH extremes, and buffer strengths, among other interfering substances.

Abstract: A safety system shield which protects the head, facial, throat, and upper thorax regions of the body from exposure to biological, chemical, and physical matter that may take the form of solids, liquids, or aerosols, and includes a thin flexible shield which is curved, and transparent. It is shaped to rest on the anterior shoulder, and thorax region of the body, thereby allowing the head to look in any direction. This relieves the wearer's head of the weight of the shield while affording maximum protection. The safety shield system is ultra-light weight thus, reduces wearer's fatigue, and eliminates headaches, resulting in the enhancement of safety, and the reduction of accidents. The safety shield is flexible allowing it to conform to the size, and curvature of the wearer.
