A relay device may include an armature that moves between a first position that electrically couples the armature to a first contact and a second position that electrically couples the armature to a second contact. The relay device may also include a relay coil that receives a voltage to magnetize the relay coil, thereby causing the armature to move from the first position to the second position. The relay device also includes an additional coil that couples in series with the relay coil via a switch. The relay device also includes a drive circuit that causes the switch to couple the additional coil to the relay coil in response to receiving a signal indicative of the relay coil energizing.

A control module for a reversing contactor includes a housing configured to mount to forward and reverse contactors. The control module is configured to receive command signals for the forward and reverse contactors and provide the command signals to an interlock circuit included within the housing of the control module. The interlock circuit is configured to use the forward and reverse commands as well as feedback signals corresponding to the current status of the contactors to prevent both the forward and reverse contactors from being closed in tandem. The control module is also configured to mount to contactors having different physical sizes. The housing may be configured as a telescoping housing, where one portion of the housing is fixed and a second portion of the housing slides with respect to the fixed portion of the housing to adjust the width of the control module.

A system and method for aging an unaged distilled spirit (raw product) to produce rapidly aged spirits over a very fast period of time whereby the rapidly aged spirit has flavor profiles and taste that replicate the flavor and taste of alcoholic beverages that are traditionally aged. A processing vessel dedicated to holding the unaged spirit and mixing the unaged spirit with charred wood staves is provided. Pressurized, filtered air is added to the processing vessel for a period of time and then the filtered pressurized air is released and vented elsewhere. Then, a vacuum pump is used to vacuum remaining air in the processing vessel for a period of time, and then the vacuum is quickly released resulting in violent, quick agitation of the remaining air and spirit in the processing vessel. A computer application is used to schedule the sequence of steps for a recurring period of time.
