Abstract: An emu shoe for discouraging combat and aggression towards other emu which consists of a single, flat foot cover of characteristic shape which foot cover includes instep and heel panels that are firmly secured by VELCRO.TM. adhesive to maintain the shoe in place through all bird activity.

Abstract: Sensitive proteins in human biological secretion samples are preserved by dispersing them in an aqueous solution containing from 0.05 to 0.5M of a buffer which is effective to maintain the solution pH within the range of from 6.5 to 8.0; from 0.1 to 10 wt. % of a non-immune animal protein selected from the group consisting of albumin, ovalbumin, casein, glycoprotein and mixtures thereof; from 40 to 2000 kallikrein units/mL of an enzyme inhibitor of trypsin, chymotrypsin, kallikrein or plasmin; and from 0.01 to 0.1 wt. % of a bacteriostatic agent. The solution preferably also contains from 5 .mu.M to 1 mM of a protease inhibitor; and from 1 to 10 mM of a chelating agent. Optimally, the enzyme inhibitor is aprotinin, the protease inhibitor is phenylmethylsulfonylfluoride, the non-immune animal protein is bovine serum albumin, and the protease inhibitor is phenylmethylsulfonylfluoride. 0.0 to 0.15 mM of a water-soluble non-interfering salt, such as NaCl, may be desired.

Abstract: An expansion joint cover comprises a pair of elongated rigid frame members, each of which includes a generally vertical, longitudinally continuous wall portion and a multiplicity of longitudinally spaced-apart, substantially horizontal plate-like tongues supported in cantilevered relation from the vertical wall portion at locations spaced from the upper edge of the wall portion and in longitudinal alignment. The longitudinal spacings between adjacent tongues of each frame member are not less than the widths of the tongues of the other frame member such that in the cover as installed in the expansion gap the tongues of each frame member project into the spaces between the tongues of the other frame member, and a generally longitudinally continuous bridge is formed by an intervening of the tongues of each of the frame members between the tongues of the other.

Abstract: An expansion joint cover comprises at least one elongated frame assembly which includes a base member having a bridge-supporting rib adjacent the gap and a cover-supporting flange spaced laterally outwardly from the rib, the cover-supporting flange having an upwardly open groove and an abutment located laterally outwardly from the groove, relative to the expansion gap. A cover member having, in cross-section, a web portion, a bridge-supported flange extending down from the underside of the web portion adjacent to the gap and generally vertically above the rib of the base member and a retainer rib extending down from the underside of the web portion, is fastened to the base member of the frame assembly by longitudinally spaced-apart, generally U-shaped spring clips received on the retainer rib of the cover member and in the groove of the base member.
