Abstract: This invention relates to the remote monitoring of the floating roofs of large storage tanks, including tanks used for storing liquid petroleum products or other chemicals. The invention is used to monitor the position and flexure of the roof and other conditions such as vibration; the presence of vapors or liquids from water, hydrocarbons, or other chemicals; the presence of snow; or the presence of intruders. The invention can be connected to a monitoring system using wired or wireless means and can be used for routine status monitoring or for notifying plant operators in the event of alarm conditions. The invention can be completely self-contained and is suitable for encapsulation and use in harsh environments.

Abstract: An apparatus for the wireless and remote monitoring of covered floating storage tanks monitors roof position, flexure, fires and the presence of vapors or liquids from water, hydrocarbons or other chemicals. The apparatus relies upon on one or more encapsulated intelligent sensor units and communication units. The sensors are deployed on the floating roof of a storage tank and the communication units are deployed near the top wall of the floating roof storage tank or on the fixed roof of the tank.

Abstract: A floating storage tank roof having a roof cover level monitor apparatus uses a flexible rod having a first end in contact with the storage tank cover bottom surface and a second end in contact with a base mounted to the top of the storage tank roof. As the rod flexes the second end of the rod is pushed into a slot within the base and against a resilient member within the slot. Within the slot are disposed proximity switches. As the rod second end sinks into the slot the proximity switches are actuated by mechanical or magnetic means. The spacing of the switches within the slot is calibrated to represent the level of the storage tank roof. A force transducer may also be used in lieu of the switches.

Abstract: A visual monitoring system for covered storage tanks, comprising in combination a storage tank, an Imaging Unit and a Communication Unit. The storage tank has a peripheral wall, a fixed ceiling and a floating roof that travels up and down the peripheral wall. The Imaging Unit is positioned within the covered storage tank and includes a Camera, a Microcontroller, a Power Source and a Wireless Communication Interface. The Camera is mounted on one of the ceiling or the wall adjacent to the ceiling and is focused upon the floating roof. The Communication Unit receives wireless communication signals from the Imaging Unit providing imaging data regarding the floating roof.

Abstract: A switch for use with an electrosurgical tool having a heatable tip connectable to a power source and a suction passage connectable to a suction source. The switch comprises a main body having a suction passage extending therethrough connectable to the suction passage of the tool. A cavity in the main body intersects the suction passage and is adapted to slidably receive a mounting post to permit slidable movement of the main body over the mounting post. The mounting post has an end protruding from the main body that is pivotally connectable to the tool. An opening extends through the mounting post that is alignable with the suction passage. In operation, the main body of the switch is manually movable between a default position in which the suction passage and the opening are misaligned to block suction and an operating position in which the suction passage and opening are aligned to permit suction.
