Abstract: The invention is a pipe coupling particularly adapted for coupling together the ends of pipes that may or may not have annular end ribs, i.e. spigot beads. The coupling embodies a gasket into which the ends of the pipes are fitted. Deformable (semi-rigid) clamping members clamp around the gasket and the ends of the pipe. These members have shallow internal annular recesses. The gasket has diametrically opposed extending ears which are clamped between mating end parts forming lugs on the clamping members. The gasket has an integral external annular rib which fits into the annular recesses in the clamping members; pipes with spigot beads are accommodated in the annular recesses of the clamping members. The clamping members when clamped (torqued) deform to apply clamping pressure to the gasket throughout the entire circumference.
Abstract: A filter assembly or unit having end caps or fittings which are held together by tie rods with a filter casing between them and sealed to them. A filter cartridge is within the casing. Each end fitting or cap is constructed to provide a slideway to receive a sliding member that seals to the end fitting and which sealing engages an end of the filter casing. The sliding members can be secured to the end fittings. The sliding members along with the filter casing can be removed laterally from the assembly, the end fittings or caps remaining coupled in an air or gas line containing fluid to be filtered. In this manner the cartridge or cartridges can be replaced in the filter casing without uncoupling the end fittings from the an air or gas line and without disassembling the cage formed by the end fittings and the tie rods.
Abstract: The invention is an improvement in mechanisms or apparatus for transporting articles or products between points such as work stations in an industrial plant or the like.

Abstract: A double barrel firearm provides a selector mechanism so that either barrel can be selected to be fired first. A pair of sears is provided cooperating with hammers. The trigger can actuate either sear that has been selected by the selector mechanism for firing either barrel first. The trigger actuates a connector. The connector can actuate the selected sear. Each sear has engagement with a part of the connector whereby when a sear is actuated, it will move the connector rearwardly, the connector being biased forwardly so that it will then come into a more forward position for engagement with the second sear. Even if the barrel selected to be fired first does not fire, the second barrel will be fired on the second pull of the trigger. The connector also serves as an inertia block so it has the capability of responding to inertia to be repositioned for actuating the second sear in the event the first barrel fires in response to the first pull of the trigger.
