Abstract: Control materials containing specified concentrations of the osteoporosis markers deoxypyridinoline, pyridinoline, C-telopeptide and N-telopeptide in a matrix that is substantially the same as that of human urine are prepared by selecting amounts of human urine that contain sufficient quantities of the markers to achieve the target levels upon concentration, lyophilizing the selected urine, optionally after clarification by filtering, freezing and thawing, and pH adjustments, then reconstituting the lyophilized material, and combining and/or diluting the lyophilized material, either before or after reconstitution, to adjust the marker contents to the target levels. Surprisingly, the markers survive this process sufficiently intact to serve as reliable control materials of known composition and concentration.

Abstract: In a reciprocating slat conveyor, at least three slat sets of at least one slat (CS) each are driven by piston-cylinder drive units (26), one for each slat set.  Each drive unit (26) is provided with a four-way proportional directional control (PDC) valve. Each PDC valve has a first position of adjustment in which it connects a first working chamber of its drive unit (26) to pressure (B) and a second working chamber to tank (T), and a second position of adjustment in which it connects the second working chamber to pressure (P) and the first working chamber to tank (T). Control logic (96) provides electrical control signals for directing the PDC valves to operate the drive units to advance more than half of the slat sets simultaneously in a first, conveying direction, and to retract the remaining slat sets in the opposite direction at a higher rate of speed. A controller compares the control logic signals with feedback signals generated by a separate linear position sensor PS for each slat set. The controller compares the desired positions of the slat sets, as determined by the control logic (96), with the actual positions of the slat sets, as determined by the position sensors PS. The difference between the desired and actual positions of the slat sets is used to generate a corrected control signal which the controller sends to proportional amplifiers (PA). The proportional amplifiers (PA) provide control signals to the PDC valves, for changing the rate of hydraulic fluid movement into and out from the working chambers of the drive units (26) for the advancing conveyor slat sets, towards establishing the desired pattern of movement of the slat sets. The conveyor includes a drive module comprising a pair of longitudinally spaced apart end frame members, each extending transversely of the conveyor, and a center frame member positioned longitudinally between the two end frame members, and also extending transversely of the conveyor. A first pair of piston-cylinder drive units extends longitudinally of the conveyor, between a first said end frame member and the center frame member. The second pair of piston-cylinder drive units extends longitudinally of the conveyor between the center frame member and the second end frame member. The drive units are connected at one or both ends to one of the frame members. Each drive unit has a movable portion that is positioned between the center frame member and one of the end frame members. Two transverse drive beams are positioned between the first end frame member and the center frame member. The remaining two transverse drive beams are positioned between the center frame member and the second end frame member. Each transverse drive beam is connected to the movable portion of a separate related one of the drive units. Each transverse drive beam is also connected to a separate set of the conveyor slats.

Abstract: A method of making a protective pad, which comprises fastening a plurality of sections together to create an outer shell, providing an inner shell made of a more rigid material than the sections making up the outer shell, fastening the inner shell to the outer shell (thereby to form a composite shell) and fastening the composite shell to a padding liner. The use of plural sections forming the outer shell reduces manufacturing costs. An overlay may be placed over the outer shell to conceal the areas where the sections making up the outer shell are fastened together. Fastening the composite shell to the padding liner may include passing through a thinned out portion of the hard inner shell, or it may bypass the inner shell altogether, thus avoiding the use of heavy duty stitching equipment. The step of fastening the inner and outer shells may include gluing rather than stitching.
