Disclosed are threaded seal caps suitable for sealing the ends of common screw and bolt connectors for various purposes including protective/safety, ornamentation and pressure seals in chemical and physical processes or as a guard for a switch. The seal caps include a threaded inside surface for attachment to washers having a threaded outside surface. The caps can include an o-ring gasket for sealing a pressurized connector. The washers are preferably made from a suitable section of all-thread.

A versatile tool rack assembly for holding, organizing, or displaying garden tools, house cleaning tools, home supplies, etc. with elongated shapes made of two or more rack pans (50, 52) each supported at all corners with pan support beams (14) with multiple mounting holes (24) for adjustment of the spacing of the rack pans. Rack pans are usually identical and are generally attached to the pan support beams with assembly bolts (18) and assembly nuts (42) or captured nuts (46). Rack assemblies may be attached to a wall, floor, ceiling, post, base, workbench, etc. or another rack assembly.

A pipeline survey pig includes an elongated hollow pig body having an enclosure for supporting a generally cylindrical tubular instrument chassis which, in turn, supports an inertial reference unit and associated signal processing and recording devices. A plurality of resilient cup members support the pig body for traversal through a pipeline section under the urging of pressure fluid. The cup members are spaced apart and secured to the pig body by spacer members which may be selectively provided to predetermine the axial spacing of the cup members so that the center of stiffness of the pig is in a predetermined position. The instrument chassis is secured in the pig body by a cam mechanism which is actuatable from one end of the chassis after insertion into the pig body to wedge opposed chassis door members into engagement with the pig body to enhance heat transfer between the chassis and the pig body.
