Abstract: An hydraulic centrifugal piston motor having mulitple piston circumferentially disposed at right angle to shaft axis, having a rotational power moment that occurs twice each revolution for each cylinder. The power stroke for each cylinder would occur for a duration of 90 degrees twice during each 360 degree operating cycle. Hydraulic input is applied to opposing pairs of cylinders and overlap of successive power strokes provide rotational balance and cancels net reaction forces applied to the bearings. Another feature of the motor would be the particular design of the power transfer device. The thrust of the power transfer device is applied axially to the drive shaft providing a smooth transfer between the hydraulic input power and the mechanical output power.

Abstract: A carbon monoxide Monitoring System includes a control panel and remote alarm stations. The control panel is associated with a carbon monoxide monitoring unit, an emergency AC power pack and an alarm system. Each remote alarm station includes a visual-audio alarm system and a distress signal system. The carbon monoxide monitoring unit continuously samples the personnel air supply and if the CO reaches a pre-set concentration, it will provide a primary audio-visual alarm signal to a panel alarm for the control panel operator and to each individual remote alarm station, thereby giving warning of an excess of carbon monoxide gas in the air supply to the control panel operator and to the remote workers. In addition, if a worker at any remote station is in distress, he actuates his distress signal system which energizes the control panel alarm system. The control panel operator is alerted and takes whatever action is required.
