This device releases air from the bladder of a fish brought up from depth by puncturing the swim bladder of said fish, and consisting of an elongated hollow tubular cannula having an axially extending lumen therethrough, with a means for producing an audible, visible, mechanical or electrical alert signal activated by the movement of air.

Abstract: An automatically closing drop fishing net is provided for commercial fishing operations. The drop net assembly includes an upper float ring, a lower weight ring, and a net formed in a generally tubular configuration. The upper end of the net is attached to the float ring and the lower end of the net is attached to the weight ring. The drop net assembly has several torque lines that extend from locations on the float ring on the outside of the net to locations on the weight ring that are initially angularly offset at least one hundred eighty degrees relative to their points of attachment to the float ring. The torque lines are shorter than the vertical length that the net would assume in a stretched condition with the float ring buoyed upon the surface of a body of sea water and with the weight ring suspended therebeneath and held only by the structure of the net. As gravity pulls the weight ring downwardly from the float ring in the water, tension is exerted on the torque lines.

Abstract: A structure for mounting a planar array of photovoltaic panels to a roof is formed from a set of parallel spaced juxtaposed rails which are intersected by a set of parallel spaced juxtaposed runners that extend perpendicular to the rails. Both the runners and the rails are formed of sheet metal and are shaped in cross section so as to partially surround a space.
