Abstract: Apparatus is disclosed for use with typewriters of the type having trip hammers and is adapted to receive combinations of electrical signals which uniquely define the respective characteristics and to decode the electrical signals to selectively activate the trip hammers of the typewriter. The apparatus has a number of coded plates located adjacent one another in general alignment, with each of the plates having a number of transverse slots at one edge thereof at predetermined positions. Lateral or longitudinal movement of the elongated plates between first and second positions in response to receiving appropriate electrical signals causes the slots to be either into or out of alignment with an activating member which effects triggering of the trip hammer of the typewriter. Any one of the coded plates having a slot in a nonaligned orientation will prevent activation of the particular hammer.

Abstract: A system for CO.sub.2 cooling of the cargo compartment of a refrigerated vehicle. A vessel carried by the vehicle holds liquid CO.sub.2 at pressure preferably not greater than about 125 psia. Liquid CO.sub.2 is supplied to first heat-exchanger where it is vaporized and warmed a predetermined amount while the pressure is maintained at at least about 80 psia. The pressure of the warmed CO.sub.2 is lowered to about atmospheric pressure without the creation of solid CO.sub.2, while simultaneously cooling the CO.sub.2 vapor, using a gas-driven motor through which the CO.sub.2 vapor is passed. The cooled CO.sub.2 vapor from the motor is passed through a second heat-exchanger, and a fan connected to the motor circulates the atmosphere in the cargo compartment in association with both heat-exchangers. The CO.sub.2 vapor from the second heat-exchanger is vented to the atmosphere exterior of cargo compartment.
