Patent number: 10161271Abstract: A fluid expander is disclosed as used in conjunction with an air compressor that is driven by a prime mover. The fluid expander is structured to extract useful work from a fluid stream and add that work to the work provided by the prime mover to the compressor. In some embodiments a clutch can be used to decouple the expander from the compressor if insufficient work is developed by the expander. A gear train can also be used to change the rotational speed prior to work being delivered to the compressor.Type: GrantFiled: January 26, 2016Date of Patent: December 25, 2018Assignee: Ingersoll-Rand CompanyInventors: James Christopher Collins, Marion Patrick McDonald, Jr.

Patent number: 10115288Abstract: An automatic battery fluid level monitoring system is provided. The automatic monitoring system includes a fluid consumption algorithm, programmed into a microprocessor based motor controller, connected through a communications link to a microprocessor based battery charger. The battery charger is electrically connected to a flooded type battery as well as a power connection such as being plugged into an outlet, the electrical connection from an alternator, or the like. Once the fluid consumption algorithm indicates that the fluid level is too low, a battery fluid indicator is activated utilizing a visual and/or audio display.

Patent number: 10042371Abstract: According to one aspect of the present disclosure, a drain system, including a sensor in communication with a reservoir and controller, uses algorithmic control of a drain valve to adjust the interval and duration of actuation of the drain valve to regulate a fluid level within the reservoir. In embodiments applying the drain system to a gas compressor system, the disclosed control algorithm enables the controller to prevent the loss of compressed gas through an open path out the drain and further to prevent condensate generated by operation of the compressor system from backing up in the reservoir and reentering the flow of compressed gas. The control algorithm adjusts the interval and period of actuation of the drain valve such that as operating conditions change the drain valve opens more or less frequently for longer or shorter periods in response to varying condensate load.Type: GrantFiled: December 1, 2015Date of Patent: August 7, 2018Assignee: Ingersoll-Rand CompanyInventors: Michael R.
