Abstract: A secondary drainage system for buildings utilizing pre-manufactured exterior panels. The system drains off moisture and condensation collected in joints and on the rear wall of the panels, under circumstances where the primary exterior seal or cladding have failed. An elongated collection channel is attached in inclined relation to the rear wall of a panel. The channel includes a top cover, comprised of a trough having inclined walls and oval apertures. The lower end of the channel includes an end cap with a drain tube, connected to an upper, inner portion of a receptacle box. The receptacle box is located within a vertical joint between two adjacent panels. A lower, outer portion of the receptacle box has a one-way discharge valve. Also provided are intermediate joint gutters, having open tops and a discharge outlet positioned over the trough of a collection channel.

Abstract: A prosthetic foot is comprised of a springy internal frame embedded in a resilient foot-shaped outer body. The frame is in the shape of a modified trapezoid, wherein the shorter top member and the longer bottom member are connected by a generally vertical back member, and a substantially oblique front member. A toe member extends from the bottom member into a toe portion of the outer body. A solid carbon fiber layer is embedded in the frame for strength and elasticity. A break is provided between the lower end of the front member and the bottom member to enable the toe portion of the foot to flex laterally. A flexible cord is connected across the break to prevent the front and bottom portions of the frame from separating when the foot kicks an obstacle.

Abstract: An improved prosthetic foot construction providing resilient lateral flexion as well as excellent longitudinal flexion and energy recovery includes a core frame embedded in an expanded polymer body that mimics the shape of a natural foot. The core frame extends in a generally vertical plane, and comprises a modified trapezoidal shape having an open medial region. The frame includes an upper side having a mounting bolt extending therethrough to a lower leg prosthesis, and a lower side generally parallel to the sole of the prosthesis. The rear side of the trapezoid extends generally parallel to the rear heel surface of the prosthesis, and the front side extends obliquely from the upper side toward the lower side. A ball and socket connection joins the front side and the lower side of the frame, so that the oblique front side of the frame may undergo rotational motion with respect to the remainder of the frame.

Abstract: A method of processing intermediate nickel bearing products, the method comprising subjecting the intermediate nickel bearing products to an acid leach in order to dissolve substantially all of the acid soluble magnesium bearing minerals contained therein to provide an upgraded nickel bearing residue and a leach solution. The method is particularly suitable where the intermediate nickel bearing products are nickel sulphide concentrates or nickel iron oxide calcine.
