Abstract: A floor sign comprising two substantially similar panels and an engaged slidable locking bar. Each panel has a pair of closely spaced apart tabs with an aperture through each and a tab having a boss on both sides. The two panels engage each other at their upper end by interlocking the pair of tabs with the tab bosses. The upper portions of the panels are pivotably coupled. The locking bar has an upper horizontal section and a vertically depending section and is inserted between the two panels for maintaining the panels in a spaced apart deployed position or in a collapsed position. The floor sign is deployed by pressing downward on the locking bar to insert the bar between the panels, forcing them apart at a ridge on the inner face of each panel. The bar locks to maintain the lower ends of the panels in a spaced apart configuration. To collapse the sign a user lifts upward on the locking bar via a notch in the panels to release the locking bar and permit the panels to collapse toward each other.

Abstract: A brush designed with a hook built into the handle for hanging the brush on the side of a can or container. The brush is formed by a new method in which the tufts have a tapered knot and the handle is molded around the tapered knot such that the knot is anchored in the handle.

Abstract: An apparatus for holding a pad to a rotary pad machine. The apparatus includes a base piece and a retainer piece. The base piece includes a plurality of base teeth and is attached to a pad driver disc of the rotary pad machine. The retainer piece includes quick-release tabs having locking ribs. When the retainer piece is inserted into the base piece, the locking ribs lock into the base teeth to hold the retainer piece to the base piece. Flanges on the base piece and the retainer piece hold the pad therebetween. To tighten the rotary pad holder, the retainer piece is pressed closer to the base piece until the locking ribs lock into the appropriate base teeth. To loosen the rotary pad holder or change pads, the quick-release tabs are pressed in towards each other which unlocks the locking ribs from the base teeth and the retainer piece can be removed from the base piece.

Abstract: A selected component of a fluid mixture, for example a reduced sulfur compound vapor in air, is detected by selectively adsorbing the component onto a conductive thin layer of material having a chemical affinity for such component and observing the resultant change of electrical resistivity of the layer. The sensitivity of the detector changes with accumulation of the component on the sensor. The accumulation of the component on the sensor is removed by oxidizing and evolving the component from the sensor to restore the sensor to a linear operating region. The accumulated component is preferably oxidized by reacting the component with ozone. The dynamic range of the sensor is increased by counteracting the tendency for the component to accumulate by continuously feeding back ozone to or controlling the temperature of the sensor so that the sensor operates in a linear region near null.

Abstract: In a gas ion laser of the type having a serial array of coaxially aligned axially spaced floating electrodes contained within an evacuable dielectric envelope for exciting a d.c. plasma laser pumping discharge, the electrodes and gas fill are cooled by a plurality of axially directed coolant tubes within the gas-filled envelope. The electrodes have a spherically shaped funnel portion immediately surrounding the laser beam and plasma discharge path for focusing secondary electrons back into the beam path for increasing conversion efficiency. The spherically shaped surfaces are electroplated with a tungsten-cobalt alloy to decrease sputter erosion.

Abstract: A gas ion laser employs two or more independently controlled electrical gas discharges including a longitudinal plasma arc created by a thermionic cathode and an anode and a transverse glow discharge electron beam created within a photocathode reflector. These separately controlled gas discharges are arranged in a unique topology that produces highly excited atomic ions on the optical axis of a laser cavity, giving rise to a beam of laser optical radiation characteristic of the gas ion species being excited. The longitudinal plasma arc on the optical axis is heavily populated with ground state thermal ions that are not sufficiently excited to the energetic states required for laser action. The additional energy to excite these ground state thermal ions to the upper laser states is provided by a second more energetic photo-electron and glow discharge electron beam generated by a negatively biased coaxial photocathode reflector.

Abstract: In laser absorption spectroscopy a fluid sample is irradiated with a beam of coherent optical radiation preferably in the infrared band. A detector such as an acoustic detector or thermal detector is coupled in acoustic or thermal energy exchanging relation, respectively, with the fluid medium to detect the absorption of energy, if any, by the fluid from the beam of coherent radiation. One or more of the physical or chemical parameters of the fluid or substances interacting with the fluid are changed and resultant changes, if any, are detected in the absorption of energy by the fluid to yield information concerning the fluid or substances interacting with the fluid.
