A locking cap may be selectively locked into place within a tubular opening, such as the open end of a standpipe used to charge a building sprinkler system. The locking cap may have a plug portion. A friction load can be used to limit the unauthorized removal of the plug portion.

A system for protecting an equipment surface during manufacture, fabrication, transport, storage, and installation of equipment. The system comprises an adhered surface cover to mechanically protect machined surfaces, as well as hermetically sealing any covered openings. An impact absorbing cover with a deforming layer can be attached with a fastener to provide further impact protection for the equipment surface. The system has the benefit of being lightweight to allow for easy handling and shipping, is safer to use than other methods known in the art, and has the coincident benefit of protecting larger systems that equipment is a component of.

This invention encompasses a system and a method used in the petrochemical and mechanical engineering area, more specifically in the area of protecting pipes or similarly shaped objects against external or internal damage or wear, which comprises a protective system for the ends and the inside of coated pipes, using the coating itself and other additional devices. The system is comprised of a cup (1), spacer (2), coating (3), external ring (4), and cap (5) used in the production line of the pipe-coating process, using the external coating itself, preventing corrosion and mechanical damage at the ends/bevel, in the sandblasted area of the collar and internal surface, from storage and transport to the location where it will be used, and welding in the field or on the vessel.

A woodwind reed storage and maintenance device conveniently fits directly onto the reed bearing end of a musical instrument. The storage and maintenance device includes a reed storage space, humidity control device space, and a humidity gauge. The storage and maintenance device is used to maintain a reed while still located on the musical instrument at a specifically-chosen constant humidity level for optimal performing condition and maximum reed life. The storage and maintenance device protects the reed from physical damage and from damage due to changing humidity levels in the ambient surroundings. The storage and maintenance device accurately measures and displays temperature and humidity information corresponding to the reed storage space inside the device.

This tubular member thread protector generally comprises an outer member capable of rotation in a first direction about an axis and an inner member coaxially integrated within the first member and capable of rotation in an opposite direction. The inner member comprises a flexible annular sleeve having an outer surface and an interior surface defining an interior annular space capable of receiving the tubular threaded end. One or more camming surfaces are disposed about the inner sleeve outer surface. The outer member comprises a generally annular structure having a closed end, an open end, an outer surface and an inner surface. One or more raised camming members are disposed about the outer member inner surface and are aligned with sleeve camming members during rotation, the outer member camming members press against the inner sleeve camming members to radially compress the sleeve inner surface against the threaded member.

A stopper for a container providing evidence of first opening includes an upper part with a protection cap closable on a pouring element and a ridged lower part with an upper hollow cylindrical portion disposed inside the pouring element and a lower cylindrical portion of larger diameter that is internally threaded. A frangible label is positioned between the protection cap, and a security ring is connected with the upper and lower parts with frangible bridges. An annular security crown is connected to the lower part of the stopper by frangible bridges and a cam arrangement, coaxially coupled between an outer surface of the upper hollow cylindrical portion and an inner surface of the pouring element, causes their translation and rotation. The pouring element has a duct passage and a coaxial island shutter which cooperates with a central hole in the upper hollow cylindrical portion of the lower part.

The disclosed invention provides a conduit sleeve with detachable end cap that greatly reduces the complexity of the current system that requires a multiplicity of integral sleeve conduit bodies, styles, fixtures, fittings, connectors, rigid conduits with female threading, and other receiving structures. Now, one conduit sleeve with detachable end cap can be used to protect a threaded conduit end without the need for specialty receiving structures having an integral sleeve. This is accomplished by having a single object performing both roles as conduit sleeve and end cap. The end cap portion can simply be cut or twisted off from the conduit sleeve portion at a convenient time after installation onto a rigid conduit, tube, pipe, or similar structure. The remaining conduit sleeve that is left protects the area of the rigid conduit where conduit threads would have been left exposed since they are not fully threaded into the receiving structure. In addition, the conduit sleeve may be flexible in construction, which is desirable if the rigid conduit is bent, such as along a transition area of a wall.

The present invention relates to a capsule for a substantially cylindrical vessel with a shell surface, an upper open end, and a lower closed end, wherein the shell surface, at least in the area of the open end, is of substantially cylindrical design.

In order to protect substantially cylindrical vessels against breakage in cost-effective manner, it is suggested in the scope of the invention that the shell surface above the closed end comprises at least one means for forming a free space, which is a crimp, directed at least partially inwards on the shell surface.

Here, the capsule is configured in such a way, that it can be fitted onto the bottom-side end of the substantially cylindrical vessel. The tolerance limits of the substantially cylindrical vessel are thereby compensated.
