  • Patent number: 5484524
    Abstract: A wastewater treatment plant for removal of organic matter, suspended solids and other pollutants comprising a pre-treatment chamber, a biofilm-aeration chamber and a settling chamber. Biofilm grows on biofilm support structure which is stationary and submerged in the mixed liquor of the biofilm aeration chamber. The combination of submerged or surface aeration and suspended solids particle size reduction occurs thereby creating a sufficient fluid flow within the biofilm aeration chamber. This combination of sufficient fluid flow, and reduced size suspended organic particles results in the efficient digestion of organic matter and pollutants by the biofilm growing on the biofilm support structure submerged in the biofilm aeration chamber. This results in a vastly more effective digestive process than conventional processes producing no sludge. Further, resulting treated effluent has a high dissolved oxygen content and low BOD and SS.

  • Patent number: 5481832
    Abstract: A series of large bins which can be raised and lowered on lifts in order to reach a bridge that is to be sand blasted. A skirt is attached to the upper outside edges of the bins. This skirt is raised and attached to the bridge so that the entire work area is completely enclosed. An air inlet and an air outlet are provided at either end of the enclosed work area. Air is pumped in to the work space through the inlet and is evacuated through the outlet. The outlet pressure is maintained at a higher level than that of the inlet in order to maintain a negative air pressure inside the work area relative to the outside air pressure. A grate covers each bin, providing an area on which workers can stand. As the bridge is sand blasted, all paint debris and blasting sand falls through the grates and into the bins. Smaller particles of dust are removed from the work area through the air outlet and are collected by a dust filter.

  • Patent number: 5472247
    Abstract: A locking mechanism which provides a number of resistance points, all of which function to impede the opening of a door located on the chassis of a lottery dispensing machine or any other enclosure that must be secured. The locking mechanism includes a rotating cam which sets the lock in motion. Rotation of the cam is translated into reciprocating motion of a number of bolts which move into a locked position. Once the bolts are in a fully locked position, movement of the door is impeded. If two bolts are used, they face in opposite directions. If more than two bolts are used, they all face in different directions. This makes the lock impossible to jimmy. Further, to successfully pry open the lock would require an effort great enough to cause substantial structural damage to the enclosure itself. A cam extension is also provided which provides extra resistance when the locking mechanism is in a closed position.

  • Patent number: 5440290
    Abstract: A proximity detection device for protection of personnel against exposure to hazardous radio frequency radiation. The device works by detecting the presence of people, either the operator or bystanders, who are in the system antenna's radio frequency radiation hazard zone. Upon detection, the device triggers a timer that delays the activation of alarm circuitry for a brief period of time. This time delay is instituted to minimize the triggering of nuisance alarms by a momentary intrusion in the hazard zone. If a presence is still detected after the delay time, pulsing visual and audible alarms are triggered to alert the system operator of the dangerous situation. The alarms remain activated for a timed period, allowing the operator to clear the hazard zone.
