Abstract: A dispenser system for a pressurized canister including an actuator including components such as an external housing, a valve having a top stem connector for attachment to an output hose, support pins, and a one way ball check valve having a stem fitting with an extended valve stem for engaging the pressurized canister, a pivoting actuator control or trigger, having a trigger return spring, to bias the trigger out of engagement with the valve, unless a stop pin is removed and the trigger is pivoted into operating engagement under compression of the trigger and trigger return spring by a user. The sensor may communicate with a mobile device to indicate when to stop dispensing contents from the canister.

Abstract: A drive mechanism that connects to a rotary drive component for transferring rotary motion to another component. The drive mechanism may be a conversion assembly to facilitate a connection to an existing rotary drive component and transfer the rotary motion to another component. The drive mechanism may include a drive shaft, a housing with a rotary bearing and seal, an enclosure and a drive pulley or other transfer component. The drive shaft may include a cap and flange to connect to a rotary drum and extend to a drive pulley in an enclosure.

Abstract: This invention is a process for treating an underground formation of coal by contacting the coal with a basic aqueous solution for a time sufficient to disintegrate at least a portion of the coal formation. Subsequently, at least some of the disintegrated material is removed to create permeability in the coal formation. The coal is then treated with a heat carrying fluid to recover energy values from the coal. Another aspect of this invention is a process for slurry mining coal which comprises contacting the coal with the basic aqueous solution for a time sufficient to disintegrate the coal and form a slurry, then conveying said slurry to a receiving terminal.
