    摘要： A photometric detection system including a light source, a photometric detector, and a flow cell assembly. The flow cell assembly includes a tubular liquid core waveguide having inlet and discharge ends for receiving and discharging a flow of the sample fluid. A first coupling device optically couples the light source to the waveguide at a first position along the length of the waveguide. A second coupling device optically couples the detector to the waveguide at a second position along the length of the waveguide. The first and second positions define an optical path length within the waveguide. The second position is variable relative to the first position such that the optical path length is selectively varied.

    摘要： A method for separating mixed granular material based upon dissimilar specific gravities, (such as in firearm range cleaning) thereby separating lead from backstop material. Lead falling from an airstream is airwashed by an upwardly directed second airstream. The preferred method is performed under negative pressure to control lead dust. Application to pick up and clean or recover fouled ballast rock (such as used in the rail industry). Processes and apparatus are disclosed that pick up and clean or enrich precious metal bearing ore.

    摘要： Process for pneumatic classification of mixture of granular particulates by providing an apparatus, entraining mixture, reducing velocity of entraining airstream, and airwashing falling particulates of low aerodynamic support. Specific applications include a method separating mixed granular material based upon dissimilar specific gravities, useful in cleaning firearm ranges by separating lead from backstop material. Falling granular lead particulates can also be airwashed and negative pressure facilitates control of lead dust. Also disclosed are applications that pick up and clean or enrich precious metal bearing ore, and a broad range of applications from heavy mixtures, such as landscape rock, to light mixtures such as grain.

    摘要： A concrete lid for an in-ground utilities box includes a reinforcement structure filled with concrete. The reinforcement structure includes a plastic frame and one or more reinforcing trusses that extend between opposing sidewalls of the plastic frame. The reinforcing trusses also extend substantially between the upper and lower edges of the opposing sidewalls. For example, a reinforcing truss may include a flat truss member that is substantially coplanar with the lower edges of the sidewalls, and an arched truss member that extends towards (but does not reach) a plane defined by the upper edges of the sidewalls. The reinforcing trusses include openings that allow wet concrete to pass through. The sidewalls of the plastic frame protect the edges of the lid from damage. The reinforcing trusses reinforce the concrete lid, eliminating the need for separate reinforcement material.

    摘要： A waterfowl decoy for selectively simulating feeding in water. An articulating apparatus includes a motor, a threaded rod, a weight, a motion-reversing toggle switch, and a motion-reversing sliding plate having forward and rearward-stopping tabs. The motion-reversing toggle switch is toggled forwardly when the weight moves forwardly enough to contact and move the forwardmost-stopping tab forwardly, causing the motor to reverse, and when the weight moves rearwardly enough to contact and move the rearwardmost-stopping tab rearwardly, the motion-reversing toggle switch is toggled rearwardly causing the motor to reverse, with such back and forth motion of the weight causing the body to duck in and out of the water and imitate feeding. The articulating apparatus further includes a normally closed-movement termination switch that is selectively engaged by the rearwardmost-stopping tab, and when engaged, opens and prevents power from communicating with the motor, terminating motion of the weight so as to cease the body from ducking in and out of the water, while assuring that the body is in a non-feeding position, and a normally-opened momentarily-closed electrical switching device that when closed momentarily shorts out the normally closed-movement termination switch so as to allow the body to continue ducking in and out of the water, if desired. The electrical switching device can be either a remote control switch, a timer switch, or a random generator switch.
