  • Publication number: 20190287429
    Abstract: A method and apparatus for avoidance of damage to concealed mechanical elements during construction or repair of a structure. In one embodiment, a tag is provided for installation on a plumbing or similar element prior to such element being concealed by further construction. The tag is adapted to engage a concealed element in such a way that an indicator portion of the tab remains visible after further concealing structure is installed. The visible tab's location identifies the location of concealed elements and is preferably provided with indicia identifying such purpose. In a further embodiment of the invention, adhesive indicator tape is used in conjunction with an indicator tab. The indicator tape is adapted to be applied over concealing structure to generally identify the location and extent of concealed elements that may be susceptible to puncture or damage during subsequent construction or repair phases of a project.

  • Publication number: 20190152816
    Abstract: A water treatment system is disclosed having electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite, or potable water to be oxidized. The cell has first and second opposing electrode end plates held apart from each other by a pair of supports such that the supports enclose opposing sides of the end plates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.

  • Patent number: 5787816
    Abstract: A novel method and apparatus for installing and securing auto rack side panels, either during manufacture of the auto rack railway car, or during refurbishment of the car, where covers are placed over components which clamp the panel corners. In a preferred embodiment of the invention wherein end portions of elongated dust closure plates are employed to clamp side panel corners against brackets to prevent metal-to-metal contact between the end portions of the dust closure plates and the side panel corners engaged by the end portions thereof, plate covers are installed over the end portions of the elongated dust closure plates so as to be disposed between the end portions of the dust cover plates and the panel corners, to avoid abrasion and rusting as a result of friction.

  • Patent number: 5233932
    Abstract: A shredding and feeding system for an incinerator, wherein a shredding chamber is isolated from atmosphere by means of an airlock through which material to be incinerated passes into the shredding chamber. The oxygen content of the shredding chamber is maintained below a predetermined level to minimize risk of explosions and premature incineration of material.

  • Patent number: 5091917
    Abstract: A method and apparatus for associating received pulses with one of a plurality of emitters emitting pulses at periodic intervals. Periodic pulse trains are detected by computing the difference in arrival times between each received pulse and a fixed number of previously received pulses. In the simplest embodiment, a periodic pulse train is detected when one of the computed differences is one-half of another computed difference. In other embodiments, further processing is performed to detect staggered pulse trains or other periodic patterns.
