  • Patent number: 5372126
    Abstract: A pulmonary sample collection apparatus and method are provided for the sanitary collection of pulmonary sputum samples otherwise referred to as sputum induction, without allowing escape of infectious pathogenic microbes into the ambient air. The present invention is conveniently and safely usable in outpatient settings, such as doctors' offices and laboratories. The apparatus entirely encloses the patient in a chamber. The chamber is equipped with an air exchange blower which produces within the closed chamber controlled negative air pressure. The chamber is equipped with a replacable exhaust filter unit with which to trap airborne pathogens and other potentially harmful particles. The negative internal air pressure acts to facilitate sealing the chamber to prevent escape of substantially all airborne infectious particles from the chamber.

  • Patent number: 4253691
    Abstract: A litter collecting bag is retained by a clamping device in an open-end of a tubular housing. Pawl means attached to a spring loaded handle slidingly mounted atop the housing engages a sliding toothed rod connected through the housing to the clamping device permitting the litter collecting bag to be drawn into an ejected from the housing. When the collecting bag is pressed by the housing onto a quantity of litter, the litter is driven into the collecting bag. The litter bag self-seals as it is fully retracted into the tubular housing and may be discharged later to dispose of the litter conveniently.

  • Patent number: 4123236
    Abstract: An improved high resolution chromatograph device operable at column pressures ranging between one and fifty atmospheres absolute measured at the column exit, means for closely regulating the column carrier gas velocity including intermittent stop flow operation, and sample collection chamber means to facilitate contamination free handling and concentration of collected pure sample during spectral or other analysis of eluted samples. Velocity and stop flow control without loss of chromatographic resolution permits matching operation time of chromatograph to that of spectral or other analysis devices.

  • Patent number: 4090371
    Abstract: A device for monitoring the physical and thermodynamic states and concentration of components of a fluid mixture within an operating refrigeration system to detect precursor conditions of system malfunction. Monitoring and detecting refrigeration system fluids is accomplished by continuously sampling the fluids at critical positions within the system during operation. The sampling is accomplished by means of a plurality of sensors positioned within and adapted to detect changes in the heat constants of the fluids. Electronic circuit means utilizing voltage signals derived from the sensors discriminates between normal operating conditions and malfunction precursor conditions. The electronic circuit output is applied to control operation of the system to prevent system damage and to actuate the system status visual display.

  • Patent number: 4053085
    Abstract: A seal apparatus for making demountable gas tight seals between juxtaposed dissimilar material parts in high temperature, high pressure and chemically reactive environments. The seal is comprised of two or more concentric elastomer washer seals mounted in a first juxtaposed part within a recessed channel of measured depth. The washer seals have a thickness greater than the measured depth of the channel, thereby providing contact with the second juxtaposed part interfaced with the first or channeled part. The inner concentric elastomer washer, being made of chemically relatively inert material, and the outer concentric elastomer washer being made of high resilient, therefore relatively chemically reactive material. The outer concentric washer seal is the true load bearing seal; the inner seal is a means for shielding the load bearing seal from chemical deterioration.
