摘要:
A surface treating device includes a member adapted for engaging a surface to be treated and a driver operatively associated with the member. The driver is adapted for imparting a linear reciprocating motion to the member, wherein the member engages the surface in a manner substantially perpendicular to the surface to be treated. The surface treating device further includes a dispenser for delivering a fluid drawn from a discrete fluid source to the surface being treated by the member.
摘要:
A method of cleaning a solid surface which is particularly effective for a surface having a complicated structure including slots and holes comprises immersing the solid surface in a cleaning slurry comprising a cleaning liquid and abrasive particles which are soluble in the cleaning liquid, the cleaning liquid comprising a saturated solution so as to greatly reduce the dissolution of the abrasive particles in the cleaning liquid.

A blast media for stripping coatings or other contaminants from a solid surface comprises water soluble abrasive particles and a rinse aid which reduces the amount of water soluble residues of blast media remaining on the targeted surface and which enables any residues which remain to be readily removed by fresh water. The rinse aid can include magnesium oxide or a mixture thereof with one or more surfactants.

A spray mixing nozzle and a method for reacting an acidic fluid and a basic fluid by using the spray mixing nozzle. The nozzle includes a central channel, at least one intermediate annular channel surrounding said central channel, an outer annular channel and a mixing chamber having a generally cylindrical upper section, a generally conically-shaped lower section and an axially aligned discharge orifice. The acidic fluid and the basic fluid are directed through the central channel and the intermediate annular channel into the upper section of the mixing chamber at relatively low velocities and a pressurized gas is simultaneously directed through the outer annular channel into the upper section of the mixing channel at a relatively high velocity. The high velocity gas acts to strip apart and at least partially atomize the acidic fluid stream and the basic fluid stream in the upper section of the mixing chamber. The gas and the partially atomized fluids are then subjected to a high degree of turbulence in the lower section of the mixing chamber and thereby substantially completely atomize and mix the fluids. The mixed and atomized fluids then begin to react and form a powdery or highly viscous paste product which is discharged from the discharge orifice.

The present invention is directed to a vibrating band comprising a belt-like O-ring, a housing with a vibrating device contained within the housing. The vibrating device comprises a vibrating motor, one or more batteries and a touch or push switch. The vibrating band can be used by a male user to increase stimulation for both the male and his partner during sexual intercourse.
摘要:
A blast media is provided for cleaning a metal surface by wet blasting and which comprises a particulate abrasive such as sodium bicarbonate and a corrosion inhibitor comprising an alkali metal phosphate. The corrosion inhibitor has been found to greatly reduce the discoloration of metals which have been wet blasted with alkaline salt abrasives.
摘要:
A blast media for stripping contaminants from a solid surface comprises abrasive particles and a surfactant in the form of a granular surfactant-clathrate compound formed of a surfactant and a water soluble compound having clathration capability such as urea. The surfactant reduces the amount of water soluble residues which remain on the targeted surface and enhances the removal of dirt, grease and oil from the targeted surface.
