  • Patent number: 8480957
    Abstract: Gas detector tubes may be used to determine a concentration of target gases in air. The gas detector tubes described may be read either by and optical reader or visually by the user. A gas detector tube reader having an optical reader capable of reading a length of stain, a color change and color density of a reagent in a gas detector tube. The gas detector tube may further comprise sensors for measuring the environmental conditions during sampling.

  • Publication number: 20120055815
    Abstract: Gas masks and canisters for gas masks have a chemical sorbent that protects the respiratory system of the wearer from gaseous compounds. The remaining service indication systems for respiratory protections systems provide a warning to the wearer that the capacity of the chemical sorbent to adsorb or absorb further compounds is nearly depleted. A remaining service life indication system has a computer memory device for storing information concerning the canister for determining an end of the service life of a gas mask, a canister and/or a cartridge and such devices from the input of various sensors.

  • Publication number: 20110197687
    Abstract: The disclosure is directed to a device for fluid sampling. The device may have two panels that are or may be adhered, attached or otherwise connected to opposite sides of a sampling bag having flexible walls. The panels may be used for conveniently inflating or deflating the sampling bag and obtaining fluid samples.

  • Publication number: 20060062689
    Abstract: A surface wipe for real time detection of trace amounts of toxic substances on surfaces. The wipe includes a collection surface that is swiped across a surface to be tested. The collection media filters dirt and other materials to prevent or reduce inaccurage readings caused by dirt or other foreign matter. A reactive media next to the collecting surface is impregnated with chemicals that react to the toxic substances to create a color change in the reactive media. The color change may be viewed through a clear backing.

  • Publication number: 20060042373
    Abstract: A cold smoke generating device includes an air source that may include a hollow flexible collapsible container having an expandable and compressible cavity for accepting air and air-borne reagent therein. The collapsible container is fluidly connected with a narrow flexible extension that includes an elongated cavity or chamber. Isolated and/or free reagents are disposed within the chamber of the narrow flexible extension. These reagents are capable of reacting with each other, with atmospheric air, or with other gases and fluids to generate a visible aerosol when expelled into the surrounding air.

  • Publication number: 20050224737
    Abstract: Presented is a flow metering valve that can precisely and accurately regulate the volume of the fluid-flow through entire range of measured flows. The valve comprises tubular body and moving stem in it. One end portion designated as a leading has threadely engaged stem and body. Another portion designated as a regulating has body with the stem extended to fill the tubular space longitudinally separating inlet and outlet ports. At least one of the surfaces—the inner of the body or the outer of the stem—is threaded and have their threads truncated by tapering truncation from the crest to the root. The truncated thread forms channel having cross-section tapering from one port to the other. The axially moving stem gradually changes the cross-section of the channel providing variable flow communication between the two ports. The fluid flow changes proportionally to the cross-section of the formed channel. The valve provides very fine regulation of the flow within four orders of magnitude.

  • Publication number: 20040140347
    Abstract: A mailbox is developed which comprises a separated top and bottom port. A pivotally hinged gate/tray serves for depositing the incoming mail. The gate/tray has a pocket for outgoing mail and secures the top port from theft. Under the gate/tray a fixture with short wave ultraviolet (UV) light irradiates the box inside simultaneously generating ozone for a predetermined time. This time starts after the outgoing mail is put in the pocket or the incoming mail is dropped inside. A specially designed basket provides space around the mail where sanitizing gas freely diffuses. The light source can irradiate and activate gas-releasing objects generating other disinfecting gases such as chlorine, chlorine dioxide and ethylene oxide. The bottom port is closed by a locked door and allows retrieving the mail, and setting and maintaining the UV fixture. Two signals on an outside flag indicate the beginning and the end of the sanitizing process.

  • Publication number: 20030168507
    Abstract: A mail box comprising separated top and bottom port. A pivotally hinged gate/tray serves for depositing the incoming mail. Same gate/tray has a hard-cover book-looking pocket for outgoing mail and secures the top port from theft. Under the gate-tray a fixture with short wave ultraviolet (UV) light irradiates the box inside generating simultaneously ozone for a predetermined time. This time starts after the outgoing mail is put in the pocket or the incoming mail is dropped inside. Specially designed basket provides space around the mail where sanitizing gas freely diffuses. Same light source can irradiate and activate gas-releasing material generating other than ozone disinfecting gas such as chlorine dioxide or ethylene oxide. The bottom port is closed by locked door serving for retrieving the mail, setting and maintaining the UV-fixture. Two signals on outside flag indicate the beginning and the end of the sanitizing process.
