Wall rack

A device to easily mount and hold hockey sticks to a vertical structure, such as a wall. One embodiment includes a vulcanized rubber or EPDM body portion that can be attached to a wall. The body portion has a front recess that receives the shaft of a hockey stick and grips and holds the stick in place. The device can accommodate standard hockey stick shaft widths, and enables easy insertion and removal of hockey sticks.

A system and method for protecting a genset from pole slip is disclosed. The system may comprise a generator, a prime mover and a controller. The generator includes a stator and a rotor. The prime mover is configured to drive rotation of the rotor. The controller may be configured to: determine mechanical status of the generator based on data associated with a translational displacement of the rotor; determine electrical status of the generator based on (a) a load angle or (b) the load angle and a rate of change of the load angle associated with rotation of the rotor in the stator; determine an operating condition of the generator based on fusion of the mechanical status and the electrical status; if the operating condition is a pole-slip-warning, activate an output member to display or emit a warning; and, if the operating condition is a pole-slip, activate a protective action.

Generator pole slip detection

A load management system is disclosed. The load management system may include a generator, a power source configured to drive the generator, a load bank configured to produce an electrical load on the generator, a chopper operatively connected to the generator and the load bank, and a chopper regulator in communication with the generator and the chopper. The chopper may be configured to modulate the electrical load of the load bank on the generator. The chopper regulator may be configured to monitor generator parameters and control the chopper based on the generator parameters.

Smart load bank and excitation control

A method for adjusting a fuel control system of an engine capable of operating in both a first mode during which only a first fuel is delivered to the engine and a second mode during which both the first fuel and a second fuel are delivered to the engine includes operating the engine in the first mode during which a governor output value (X.sub.M1) is established and stored in memory. The engine is then operated in the second mode during which a governor output value (X.sub.M2) is established. The governor output value (X.sub.M2) is compared with the stored governor output value (X.sub.M1) and a stored second fuel energy content value is adjusted based upon the comparison. The actual energy content of the second fuel can also be directly calculated.

A fuel pressure relief system for a dual fuel engine including at least one gaseous fuel admission valve positioned between a gaseous fuel inlet region and an air intake region is provided. The system includes a first pressure sensor positioned in the gaseous fuel inlet region and a second pressure sensor positioned in the air intake region. An electronic controller is connected to the first pressure sensor and the second pressure sensor. A gaseous fuel vent path extends between the gaseous fuel inlet region and a portion of an air intake path of the engine. A vent valve is positioned along the gaseous fuel vent path and is connected to the electronic controller for control thereby. When the differential pressure across the gaseous fuel admission valve exceeds a predetermined level the fuel vent valve is opened to relieve the pressure.
