Title: Mechanism for opening filter presses
IPC: B01D25/172
Filed: 1970-03-13
Abstract: The mechanism comprises a rigid member extending along the direction of opening movement, a member for reciprocating the member and a slipping clutch which connects the member to a pawl adapted when moved with the member to engage a plate and displace the plate to an open position. Continued movement of member in the same dirction is accompanied by slipping of the clutch and hence the relative movement between the member and pawl, whereby return stroke of the member of the pawl is repositioned relative to the length of member for engagement with the next subsequent plate during the next return stroke. The slipping clutch is provided with means for varying slip. An arrangement is provided for returning the pawl after a final opening cycle to an initial position ready for a first opening cycle.

Title: Adding iron powder to molten metal in continuous casting - forms dense zone at core of cast bars and slabs thus preventing pipe
Inventor: KIMM DIETER
IPC: B22D11/112
Filed: 1973-04-30
