Title: Guide and support rolls for continuous casting plant - using plain bearing shells so small dia. rolls can be employed
IPC: F16C13/00
Filed: 1975-11-20
Abstract: Roll for roll tracks in continuous casting plants, where the roll has an internal coolant cavity, on both sides of which are axial cooling channels extending through the roll, and on both ends of the roll is a bearing supported in a stationary bearing-block. The roll is provided with a journal at both ends, and the ends of the roll barrel surround part of the length of the journal, forming an annular cavity; the bearing blocks are fitted with a hub which projects into the annular cavity, and the coolant channel travels through the journals. A lubricant channel is pref. provided in the bearing blocks to lubricate plain bearing shells. Simple construction, high rigidity and a small dia. are achieved due to the use of plain bearings as distinct from roller bearings.

Title: Cardboard blank forming divider for bottle carton - has cross slits forming shallow auxiliary dividing pockets
IPC: B65D5/496
Filed: 1976-01-14
Abstract: A blank made of e.g. cardboard, intended to be inserted up its interiorm has a minimum number of vertical creases to form fold lines and a minimum number of slits to form auxiliary shallow compartments. For three bottles there are only two vertical fold lines and two horizontal slits, these slits being only half the total length. The folds give a compartment for one bottle, next to a double compartment. This double compartment incorporates a further divider of reduced height by bending out the portion between the two slits. Further blanks using the same principal are shown for six bottle, nine bottle, twelve bottle and four bottle cases.

Title: Water conservation system for canal lock - has column of self contained tanks built into side of lock to allow use with great water level differential
IPC: E02C1/02
Filed: 1977-04-01
Abstract: The major proportion of the water required to service the lock is stored at the lock site, and is stored in multi-storey closed structures. The lock channel may be flanked by two columns of superimposed self-contained cells. The cells are horizontally opposed to one another, are of equal height, and are empty when the water in the lock is at the high level. The level is lowered gradually by draining the water into the cells in vertically descending order. The reverse process applies in filling the lock-channel, and a vol. of water equivalent to that of two storeys of cells is transferred to the lower reach during a cycle. The cells may be provided on one side only of the lock and include suitable valve gear.
