Title: Fish processing machine - for alignment of fish with heads in same direction using vibratory conveyors
Inventor: EGGERT ERICH
IPC: A22C25/12
Filed: 1973-01-02
Abstract: The fish are fed into a shaker box assembly with axially parallel ribs through the gaps between which the fish fall oriented axially parallel onto sloping guide rails leading in both axial directions to openings in the end walls of the box leading onto conveyors with axially parallel guide rails leading to chutes which all to the level of a first pair of axially grooved cake-walls, these in turn lead to further chutes at each end descending to a final cake-walk also with axial troughs. The chutes ensure that on landing on the bottom cake walk, all the heads of the fish point in the same direction. To limit the speed with which the fish travel along the grooves, the inside surfaces of the grooves are roughened by grinding, sand-papering, sand-blasting or steel shot-blasting. Reduced handling damage to fish.

Title: Manoeuvring long reactor fuel elements into cooling pond - by pivoting from vertical to horizontal in constricted space
Inventor: BAUER ARTUR
IPC: G21C19/32
Filed: 1974-07-16
Abstract: A handling device for long reactor fuel elements comprises a carrying tube for the elements, and a mechanism for pivoting the tube from a horizontal to a vertical posn. within a constricted space. The mechanism consists of a vertical guide bar of greater length than the carrying tube and acting as a guide for one end of the tube, and of an arm attached to the other end of the tube and pivoting about a fixed point. The length of the guide bar pref. equals the length of the carrying tube plus that of the pivoting arm. Device is used for transferring fuel elements received from a storage frame inside the reactor containment for their initially horizontal posn. to a vertical posn. The mechanism requires a shorter horizontal distance than possible with a triangular frame mechanism. The water level in the cooling pond is kept low, due to the low posn. of the carrying tube when vertical.
