Abstract: The present invention relates to a comminution device suitable for use in a cooling apparatus for cooling crushable material. The device is located at a source for such crushable material and typically comprises at least two rolls in series, which are crushing rolls wherein material is crushed in a material crushing area located between said two crushing rolls. It is a advantageous feature of the device of the present invention in that the position of at least one of the crushing rolls is adjustable relative to the other crushing roll to thereby change the dimension of the material crushing area.

Abstract: The present invention pertains to a grate plate utilized in a cooling apparatus. Substantially the entire surface area of the exposed surface, that is, the surface of the grate plate that is not overlapped by a preceding grate plate, is recessed from its outside perimeter. The recessed exposed area is defined by alternating rows of (1) substantially tubular, hollow air distribution conduits that travel substantially the entire length of the recessed exposed area in a direction parallel to the movement of solid material through the cooling apparatus. The tubular air distribution conduits have two side walls and a top surface with which the solid material transported to the cooling apparatus comes into contact, and (2) narrow, open, secondary air distribution channels that also travel substantially the entire length of the recessed exposed area in a direction parallel to the movement of solid material through the cooling apparatus.

Abstract: A Central Processing Unit (CPU) may be conveniently and selectively connected to a plurality of Cathode Ray Tube (CRT) terminals through the use of a connection station provided with adapter jacks for interconnecting the CPU and CRT operating cables. The connection station includes an insulated panel in which the adapters are positioned and an enclosure in which the insulated panel may be retained. The insulated adapter panel is preferably made out of a three layer phenolic board so that appropriate identification can be conventionally engraved on the board, and the insulated construction of the board prevents electrical interference between separately connected cables. The connection station permits remote connection of CRT terminals to the CPU without the necessity of running long cables back to the CPU which might be located at a considerable distance from the terminals.
