Abstract: The invention includes a system for monitoring the performance of an automatic dosing siphon utilized in reservoir which is a part of a wastewater treatment system. The siphon includes a bell type cover, a fluid trap having one leg extending upward into the bell, and an outlet discharge pipe connected to said trap. A flow detect switch is located in the discharge pipe. Upon siphon activation the switch is opened and a countdown timer is reset. After draining the reservoir, the switch closes and the timer starts counting down a predetermined time period. If the siphon doesn't activate, time expires and an alarm is triggered. A second system utilizes a solenoid drain valve located above the outlet portion of the siphon trap such that upon time expiring the valve opens, the tank drains, and the timer resets. The valve automatically reprimes the siphon. The system continues to monitor the siphon and initiates an alarm upon subsequent siphon failures.

Abstract: A generally L-shaped bicycle rack includes upper and lower intersecting leg portions, each including side walls having outwardly extending peripheral flanges which may optionally engage nails or screws for the purpose of securing the rack in a selected location. An arcuate well disposed centrally in the rack receives an outer circumferential portion of a bicycle wheel to support a bicycle for storage purposes. Aligned pairs of notches in the peripheral flanges of the upper and lower legs allows one or more of the racks to be secured in a variety of different mounting configurations. In a first alternative, the rack may be secured to a vertical wall to store a bicycle in a vertical orientation. In a second alternative, a plurality of racks may be secured in sequential adjacent relation to form a rack for storing multiple bicycles. A tubular member extending transversely through the upper leg of the rack may receive cables or chains for locking a bicycle to the rack.

Abstract: Toxic and hazardous organic materials are photochemically and thermally changed into innocuous and environmentally acceptable products through the proper application of solar energy. The present invention is especially well-suited for the destruction of polychlorinated biphenyls (PCB's) which are resistant to conventional incineration The method and apparatus described herein are also capable of handling liquids, solids or vapors, with only minor operating modifications.
