Abstract: CURTAIN TRACK WITH TRAVERSE CORD            ABSTRACT OF THE DISCLOSURE:         The curtain track with a traverse cord has at least one guidance channel in which the curtain hangers to which the curtain is to be attached are longitudinally freely movable.  The cord is also positioned within this track and is led over turn-around or exit rollers at the end of the track.  The curtain hangers are in frictional engagement with the cord, so that they can be actuated by the cord but stop when a resistance arises, whereupon the cord slips past them.  The curtain can be operated both with the traverse cord and also by throwing.

Abstract: A method and apparatus for protecting an ion-exchange resin in a uranium and/or related values recovery operation from poisoning by polythionates contained in the leach solution.  A guard chamber containing a catalytic material is positioned in the leaching circuit upstream of the resin so the leach solution will pass through the catalytic material before it contacts the resin.  The catalytic material, e.g. activated carbon, converts the polythionates to non-poisoning thiosulfates, sulfites, and water which offer no poisoning threat to the resins.  An oxidant, e.g. oxygen, is added to the leach solution before it passes through the catalytic material to speed up the catalytic reaction.

Abstract: A B S T R A C T             A combination pressure regulating and flow control valve having a first fluid passage interconnecting an upstream port and a down-stream port. An adjustable pressure regulating valve is mounted in the first fluid passage to provide a reduced pressure at the downstream port. An adjustable flow control valve is mounted in said first fluid passage for selective provision of either a meter in or meter out action on fluid flowing through said first fluid passage. In parallel with said flow control valve is a spring biased check valve for selective provision of free flow in a direction opposite to the metering action of the flow control valve. A parallel second fluid passage in the valve interconnects the upstream port with the downstream port. Mounted in the second fluid passage is an adjust-able spring loaded pre-exhaust valve which is vented to the upstream port.          When a meter out flow takes place from the downstream port through said first fluid passage to the upstream port the pre-exhaust valve is set to allow flow through the parallel second fluid passage until a pre-set pres-sure at the downstream port is reached and then it closes against flow.

Abstract: Abstract of the Disclosure In an agricultural implement for use in ground breaking procedures including a frame adapted to be moved over the underlying terrain in a given direction, at least one ground breaking tool, a pivot connecting the tool to the frame for pivotal movement thereon about a generally horizontal axis generally transverse to the direction of movement between a forwarding ground breaking position and a rearward inoperative position and releasable means inter-connecting the tool and the frame for normally holding the tool in the forward position and for releasing the tool for movement to the rearward position upon the tools encounter-ing resistence sufficient to damage the implement.  The in-vention contemplates the improvement wherein the releasable means is a replaceable, fracturable element interconnecting the frame and the tool at a location remote from the pivot and disposed in a plane generally transverse to the pivot axis so that resistence encountered by the tool will place the element in tension with little or no compression force imposed on the element.  Upon fracture, the element is there-by stretched as opposed to being expanded and therefore is easily replaced.
