The portable apparatus for cleaning surfaces comprises a tank (2) associated with a base (3), said tank (2) comprising at least one couple of chambers (5) predisposed to contain respective abrasive materials, said chambers (5) being hermetically separated from one another; at least one couple of mixing valves (13) associated with said base (3) and connected with respective said chambers (5) each said mixing valve (13) being predisposed to receive said abrasive material contained in said respective chamber (5) and to mix said abrasive material with a predetermined amount of compressed air.

A powder for cleaning an internal body part and/or an implant, in particular by means of a powder jet device, wherein the powder is sterile as a result of a sterilizing process.

Shot-peening powder that has ceramic particles. The powder having more than 95% by mass of beads. The beads having a median size D.sub.50 greater than 50 μm and less than 1200 μm, and having a value (D.sub.90−D.sub.10)/D.sub.50, or “S”, such that S≤−0.126.Math.ln(D.sub.50)+0.980.

A method for removing dental material is disclosed. The method may include suspending, by a hydrated polymeric material, a quantity of abrasive media. The hydrated polymeric material and suspended abrasive media may then be pressurized. Accordingly, an abrasive stream may be formed by expelling, under pressure, the hydrated polymeric material and suspended abrasive media from a nozzle. The abrasive stream may be precisely applied to a tooth to abrade the enamel or dentin thereof as a drilling instrumentality.

A depowdering apparatus for depowdering a cake comprising a build part includes a depowdering chamber, a blast nozzle, and a build elevator. The depowdering chamber includes a bottom surface and a build inlet extending through the bottom surface, where the build inlet includes an inlet axis that is substantially vertically oriented. The blast nozzle is positioned within the depowdering chamber and oriented to direct a fluid stream toward the inlet axis. The blast nozzle is laterally spaced from the inlet axis and operable to revolve about the inlet axis on a travel path encircling the inlet axis. The build elevator is arranged below the build inlet in a vertical direction and is operable to raise the cake comprising the build part through the build inlet and into the depowdering chamber along the inlet axis as the blast nozzle is revolved about the inlet axis on the travel path.

The present invention aims to provide an interlayer film for a laminated glass having recesses in the shape of engraved lines on both surfaces to exhibit excellent deaeration properties in production of a laminated glass and suppressing formation of a moire pattern when unwound from a rolled body thereof. The present invention also aims to provide a laminated glass including the interlayer film for a laminated glass, a method for producing an embossing roll suitably used for production of the interlayer film for a laminated glass, and a method for producing the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass, having a large number of recesses on both surfaces, the recesses each having a groove shape with a continuous bottom and being regularly adjacent and parallel to each other, the interlayer film having a glossiness on a surface with the large number of recesses measured in conformity with JIS Z 8741-1997 of higher than 3% or a haze value measured in conformity with JIS K 7105-1981 of 87% or lower.
