Abstract: A trigger mechanism for a shotgun with superposed barrels provides certainty in the firing of the second shot from the upper barrel after firing of the first shot from the lower barrel. The trigger mechanism includes a cam engaging the sear for the upper trigger and having an inverted L-shaped opening and a arcuate slot. The cam is biased by the hammer for the lower barrel into a position in which the pins prevent movement of the cam and release of the upper hammer sear. Upon release of the trigger following the firing of the first shot from the lower barrel, a spring biases the cam into a position in which it can be moved by a subsequent action of the trigger to actuate the upper sear to release the hammer for the upper barrel and fire the second shot. The cocking nose of each sear has a circular head co-acting with a complementary notch in the hammer to provide self-centering action in the cocked position.

Abstract: An adjustable shoulder pad for use on the end of the stock of a rifle or shotgun, containing a number of generally parallel, elongate slots of essentially consistent size and configuration, extending from side to side through the pad. These slots define a number of struts that angle downwardly at a compound angle, that is, slots that are in an angular relationship to each of two planes that are orthogonally disposed. One of such planes is the one in which the bullet or shot is to travel, whereas the other plane extends laterally away from the shooter. The struts defined by these slots tend to bend and buckle somewhat at the time the shooter places my adjustable shoulder pad against a designated shoulder, so as to cause the pad to conform to the configuration of his shoulder. Further tendency of the struts to buckle is encountered at the time the gun is fired.

Abstract: Method for retrieving lobsters or similar objects from the floor of a lobster pound or other shallow water body are described. An upward flow of water is established in a flexible conduit or passageway of size sufficient to accommodate the objects to be lifted. This is accomplished by a low pressure air lift particularly suited for non-traumatic handling of lobsters. Objects to be lifted are drawn into the upward flow as the flexible conduit is moved over the bottom. As objects rise to the surface they are guided or diverted by a transfer guide chamber or coupling onto a conveyor which carries the objects onto a deck or support platform floating above the water surface. The transfer chamber and conveyor shed water away from the lobsters or other objects. The transfer guide chamber, conveyor and a pivotable boom for supporting the flexible conduit in an "S" configuration are attached to a deck or support platform floating above the surface.

Abstract: A transparent cylindrical insect trap provides a bottom entry to a circular truncated entry cone that exits into a cylindrical entrapment chamber, all configured to inhibit insect exit therefrom. The trap top provides a screened orifice to allow volatile olfactory attractant to move upwardly out of the entrapment chamber and entry orifices allow it to move downwardly therefrom. Parts of the trap are colored to provide an optical attractant. The death of insects is hastened in the trap by excessive heat from the `greenhouse` effect and over-exertion caused by the trap design. Both attractants and trap structure cause selective entrapment of wasps.

Abstract: An apparatus fitted over the end of a sand blasting tool, for forming around the jet of sand, a thin water cocoon to eliminate sand dust during sand blasting operations. In one example, the jet of sand passes through an axial bore in the apparatus fitted over the sand blasting tool creating a negative pressure. Water, which is supplied from two chambers in the apparatus adjacent to the axial bore and located on the inner face of the apparatus at the junction of the apparatus and the sand blasting tool, is drawn by the negative pressure created by the sand jet across the inner surface of the apparatus into the axial bore around the sand jet. Air from intake holes in the apparatus causes the water to atomize as it is being drawn into the axial bore. The sheeting effect on the water across the apparatus inner surface combined with the misting effect from the air intake holes causes a thin, cylindrical mist to form around the jet of sand.
