Abstract: ABSTRACT           A process for recovering metallic values by put-ing the values into solution and separating undesired min-eral matter from the solution using countercurrent flotation is provided.  The process involves leaching metallic values from host rock, conditioning the resultant ore pulp with the required reagents to achieve selective flotation of mineral matter in the metallic values solution, introducing the con-ditioned ore pulp into flotation cells, along with counter-flow of solution from an immediately subsequent flotation step, wherein simultaneous washing and flotation is achieved and the mineral matter is removed leaving a solution of the metallic values.  The resultant mineral matter froth product is subjected to subsequent stages of flotation and simultan-eous washing with counterflow of solution removed from each subsequent stage of flotation, water and/or barren solution being used for washing in the final flotation stage.  The addition of water and/or barren solution to the final stage is controlled to maintain the desired concentrations of the advancing solutions.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved device for recording, comparing and displaying the growth of different members and generations of a family over a period of years.          The device has an elongated base member which is mounted on a suitable wall.  The base member has a vertically extending groove which slidably receives a rearwardly extending tongue portion of a slide member.  The slide member also has a forwardly extending arm portion, wing portions which extend laterally across the face of the base member, and an upwardly extending tree-shaped portion.  The family name or family tree is entered on the tree-shaped portion of the slide member.  A child stands against the wall in front of the device and the slide member is moved downwardly along the base member until the arm portion contacts the top of the child's head.  The slide member is held in this position and a horizontal line is then drawn on the front face of the base member along one of the wing portions of the slide member and the name of the child and the date is then inserted on the top of the line.  This is done periodically over a number of years for different members of the family.  The children of one generation of the family may be recorded and compared on one side of the groove and the children of the next generation recorded and compared on the other side.  When the record is complete, the apparatus provides an accurate historical record of the family's growth patterns over the generations used and a very interesting display which may be hung in a prominent position in one's home.

Abstract: Abstract of the Disclosure A single sheet of standard grade plastic laminate material is bent at two locations to form it into a side wall and two end walls corresponding to the side wall and two end walls of a bathtub recess.  Following forming, one end wall portion of the wall covering is loosely folded over the opposite end wall portion.  Then, the partially folded wall covering is pushed endwise into a rectangular cardboard box having a normal thickness which is substantially smaller than the initial depth of the partially folded wall covering.  The box with the partially folded wall covering inside is moved through a rectangular opening provided in a rigid mandril, sized to be substantially equal to the normal outside dimension of the box.  The mandril forces the outwardly bulging side walls of the box inwardly and reshapes both the side walls of the box and the side and end walls of the partially folded wall covering therein.  In so doing, the end walls of the wall covering are slid in position an amount sufficient to cause the side and partially overlapped end walls of the wall covering to bow inwardly until the wall covering has assumed a new configuration which is substantially within the normal rectangular shape of the box.  The frictional contact between the backing layer of the wall covering and inner surface portions of the box in contact therewith serve to hold the wall covering in such new configuration, so that the box will retain a substantially rectangular shape.
