Means and method for providing a non-freezing catalyst solution

A non-freezing catalyst solution carries a platinum group metal compound admixed with an antifreeze compound which is blocked from reaction therewith by a blocking agent. The blocking agent is selected from the group consisting of hydrogen chloride and lithium chloride. All of the materials are soluble in solution at room temperature.

Method and apparatus for controlling a lifting magnet of a materials handling machine

An apparatus and method for controlling a lifting magnet (12) of a materials handling machine (10) to eliminate arcing between contacts (70-80) within the magnet controller (26) as is well as is large voltage spikes. The controller (26) selectively excites the shunt field windings (66, 68) of a direct current generator (22). The magnitude and direction of the current passing through the shunt field windings (66, 68) is varied by the magnet controller (26) to control the magnitude and polarity of the voltage at the generator output (23). The armature (60) of the generator (22) is rotatably driven by a hydraulic motor at an essentially constant speed to minimize voltage variations at the output (23) of the generator (22). At least the drop cycle is controlled through use of a current transducer (200) that senses current flowing to the lifting magnet (12) so that the electronic controller is able to control the flow of current to the lifting magnet (12) based upon the sensed current in the magnet circuit.
