A method for grit blasting tubes and for blowing swabs through tubes, automatically sensing that the swab has passed through the tube, and logging the event. Also, various methods are used for inserting the swabs into the tubes efficiently.

Method of cleaning tubes

A device and method for vacuuming solid particles out of a chemical reactor tube. One embodiment comprises the step of substantially reducing the vacuum level applied to the vacuum conduit when the conduit reaches a desired depth within the reactor tube by using means responsive to the depth to which the vacuum conduit is inserted into the reactor tube.

Vacuum attachment and method

A seal for sealing against the interior of a tube includes upper and lower rigid plates with flexible plates between them, which are compressed to form a seal.

Seal for tube

A device and method for loading pellets into chemical reactor tubes.

Device for loading chemical reactor tubes

A device and method for identifying the tubes in a tubesheet, including locating a support element along a portion of the tubesheet with at least one means for identifying the location or condition of the adjacent tubes.

Device and method for identifying the row number on a tubesheet

A saw blade includes a blade body which defines a first side surface and a second side surface, wherein (i) the blade body has a multiplicity of discrete dimples formed on at least one of the side surfaces, (ii) the blade body is made of metal, and (iii) each of the multiplicity of dimples is formed by a process which includes the step of deforming the metal so as to create an indentation in the side surface in which the dimple is formed. The saw blade further includes a plurality of cutting teeth extending from an edge of the blade body. Moreover, the deforming step includes the step of deforming the metal with pins on a die plate of a punch press.

Saw blade having dimples formed by process of deforming blade body

A tool having a body with two broad sides and a margin along which a cutting edge extends, and discrete, discontinuous protrusions from at least one of said broad sides, spaced from said cutting edge and from one another. The protrusions can take the form of concave dimples with a ridge on their perimeter or convex dimples with a smooth outermost surface, with or without complementary concave dimples, which preferably, but not necessarily, have ridges on their perimeters.

Dimpling

Saw blade

A circular saw blade with improved stability, the blade having a plurality of radial expansion slots, preferably having a 'J'-shape. The blades may also have a plurality of arced body slots and may be coated with a 'TEFLON' paint mixture.
