Lateral escape of ink from between the end face (A) of a duct roller (1) and the side wall (3) retaining the duct roller is prevented by extending the length of the duct blade (11) beyond the axial extent of the duct roller and placing an end wall portion (4) in the end wall which is resiliently pressed against the end face (A) of the duct roller and, further, resiliently engaged with the top face of the duct blade (11) to form a tight seal and prevent escape of ink laterally from between the du...

A non-leaking flush toilet system that eliminates the need for using wax gaskets or rings on a toilet system. Such system having a substantially flat surface that is affixed to the base outlet opening of a flush toilet. The toilet system further includes an upper portion having inner and outer clearance surfaces, and an extension member that projects downwardly from the upper portion. Attached to the exterior surface of the extension member is a sealing boot. The sealing boot having a plurality ...

A mending apparatus for a leakage flux gap, to mend a shield having an opening, so that the electromagnetic radiation source is completely circumscribed, and the electromagnetic wave does not emanate to external. The mending apparatus has an additional metal plate and an S-shape common clip. The S-shape common clip is used to connect the shield and the additional metal plate, so as to seal the opening. The additional metal plate and the shield can be inserted into two spaces of the S-shape clip ...

A clamp for the permanent repair of leaking underwater pipelines providing improved sealing qualities against high pressures, as well as a feature which is designed to decrease the erosion of submerged pipelines which are subjected to erosive action of abrasive materials such as sand, fine gravel or silt in motion and providing for relatively easy and rapid installation under adverse diving conditions.

A system and method for detecting, and then specifically locating, a leaking tube or tubes from among a plurality of tubes which extend through a chamber and are accessible at their opposite ends from outside the chamber, such as, for example, cooling tubes of a steam condenser. The system includes a reservoir containing a supply of tracer fluid, a plurality of conduits forming a matrix which releases tracer fluid in a controllable manner into predetermined groups of tubes without interruption o...

An accessory for detecting leaking and flowing conditions in safety valves and safety relief valves utilizes a load sensing device to sense a change in a load on the valve of the safety relief valve caused by a displacement of the valve disc and provides a low-voltage output signal indicating the nature of the load change.

An apparatus for transferring leaking drums to a salvage drum utilizing a liftgate assembly having a vertical rail for supporting a liftgate and a drive mechanism for raising and lowering the vertical rail, the apparatus including a lift boom assembly having a chain mounted thereon with a drum lifting clamp secured to the chain for engaging the leaking drum and a pair of tubular pocket assemblies mounted in a vertically spaced relation on the vertical rail and a pair of pin assemblies mounted on...

A process for repair of leaking fuel tanks containing gasoline, diesel fuel, and benzene ethyl alcohol mixtures has been incorporated which makes it economically feasible for repair of all fuel tanks made of metal. The process includes prepairing the fuel tanks by steam cleaning, sand blasting, applying liquid polyvinyl chloride and special curing process. This process completely envelopes the fuel tank in a plastic cover which adheres to the metal of the tank and seals off any fuel leaks.

The invention is a flexible portable container for leaking oil tanks which is designed to stop oil spills at their source by preventing the oil from entering the water. The invention in its preferred construction consists of flexible plastic sheets heat-sealed into a shape and size somewhat larger than the oil tank in which it will be used, except for very large tanks, in which multiple units of the invention are used. The top opening is provided with radiating expansion tubes attached to the pe...
