Abstract: An apparatus for and a method of handling grown crystal ingots from a crystal-growing furnace, which apparatus and method include: lifting and moving an upper crystal chamber with the crystal supported therein to one side of the furnace; and gently lowering the crystal into a lower crystal chamber positioned beneath the upper crystal chamber and on a wheeled vehicle, which permits ease in removal and transport of hot heavy crystals with minimum damage or fracture.

Abstract: A scan-lock control device is provided for use with a high frequency receiver in a manner which adds frequency scanning and lock-up functions to the receiver without affecting any of the receiver's other functions. The scan-lock control incorporates an interface unit which can be operatively connected to the receiver to interconnect scanning and lock-up circuits to the receiver. The scan-lock device also incorporates a novel multiplexer unit which is modular and expandable and has a plurality of plug-in cards operatively associated therewith; each card having programmed thereon a frequency data channel which may be selectively scanned.
