Abstract: A truck includes an alternator having a direct current electrical power output. The truck also includes a combined inverter and charger unit having an alternating current electrical power output, a house battery and a starting battery. The combined inverter and charger unit is configured to charge the house battery and the starting battery. The truck further includes a day cab forming an interior space and a climate control unit for conditioning the interior space of the day cab. The climate control unit is adapted to be powered by an alternating current electrical source. The climate control unit is powered by the alternator through the combined inverter and charger unit when an engine of the truck engine is running, and is powered by the house battery or the starting through the combined inverter and charger unit when the engine is not running.

Abstract: This patent application describes (a) software to help people design monitoring systems and (b) methods to facilitate enhanced data flow management (including from large numbers of simultaneous sources), diagnostic and statistical analyses based on novel concepts of data compression using statistical state space techniques. The design assistance is structured around known but not widely practiced procedures such as documented in Graves, Rens and Rutz (2011). For data flow management, the present invention may transmit and store an estimated state space model only when the last stored model is not adequate to predict recent observations. It may also transmit and store outliers and samples of regular observations. This unique data storage format requires new methods for data analysis to properly extract the information contained therein.

Abstract: A truck includes an alternator having a direct current electrical power output. The truck also includes an inverter having an alternating current electrical power output, and a battery. The truck further includes a day cab forming an interior space and a climate control unit for conditioning the interior space of the day cab. The climate control unit has a conditioning capacity rating that is not greater than 7,000 British thermal units per hour (Btu/hr). The climate control unit is adapted to be powered by an alternating current electrical source. The climate control unit is powered by the alternator through the inverter when an engine of the truck engine is running and powered by the battery through the inverter when the engine is not running.

Abstract: A hammermill having a housing, a rotor assembly, a plurality of hammers, and an attrition plate assembly is provided to reduce oversized particulate material to a desired size. The housing defines an enclosed work space. The rotor assembly is disposed within the housing for rotation about a longitudinal axis of the housing. The plurality of hammers is coupled to the rotor assembly and is disposed within the enclosed work space. Each hammer having an impact end, a connection portion adapted to couple to a portion of the rotor assembly, and a shank portion extending between the impact end and the connection portion.

Abstract: A hammermill having a housing, a rotor assembly, a plurality of hammers, and a attrition plate assembly is provided to reduce oversized particulate material to a desired size. The housing has a sidewall that extends between an inlet end and an discharge end which defines an enclosed work space. The rotor assembly is disposed within the housing for rotation about a longitudinal axis of the housing. The plurality of hammers is coupled to the rotor assembly and is disposed within the enclosed work space. The attrition plate assembly has a generally circular configuration and is removably secured to the sidewall within the enclosed work space of the housing.

Abstract: A hammermill having a housing, a rotor assembly, a first plurality of hammers, and a first attrition plate assembly is provided to reduce oversized particulate material to a desired size. The housing has a sidewall that extends between an inlet end and an discharge end which defines an enclosed work space. The rotor assembly is disposed within the housing for rotation about a longitudinal axis of the housing. The first plurality of hammers is coupled to the rotor assembly and is disposed within the enclosed work space. The first attrition plate assembly has a generally circular configuration and is removably secured to the sidewall within the enclosed work space of the housing.

Abstract: A hammermill having a rotor assembly and a screen bar assembly is provided to reduce oversized wood chips. The hammermill may also be used to reduce wood and/or bark, the rotor assembly includes flexible hammers which are pivotally attached to allow each flexible hammer to move radially inward or radially outward during rotation of the rotor assembly. Each flexible hammer preferably includes a recess with a portion of a support rod disposed therein to limit radial movement inward and outward relative to the rotor assembly. The screen bar assembly includes a plurality of screen bars having a beveled surface formed along one edge of each screen bar disposed adjacent to the rotor assembly. The flexible hammers allow the rotor assembly to rotate at lower revolutions per minute which reduces the amount of fines and undersized wood chips produced by the associated hammermill.

Abstract: A locking device for preventing relative rotation of pretorqued compression nuts used in face seal mechanical fittings includes an inner member having a cavity sized to slide onto and non-rotatably enclose the male or first nut of the fitting, an outer member having a first cavity sized to rotatably receive the inner member and a second cavity sized to slide onto and non-rotatably enclose the female or second nut of the fitting, and at least one set screw projecting inwardly through a threaded borehole in the outer member to non-rotatably engage and lock the inner member.

Abstract: A seal for interconnecting a vibrating plenum chamber to a stationary air duct for air flow communication therebetween. The chamber defines an inlet duct bounded by an upstream facing annular sealing surface. A baffle member is attached to, and encircles, the adjacent end of the stationary air duct. The baffle member comprises a pair of outwardly converging annular sides sealingly joined at their outer radius, with the innermost annular portion of one side attached to the stationary air duct and the innermost annular portion of the other side attached to a sealing member defining an annular surface slidingly engaging the upstream facing annular sealing surface on the inlet duct.
