Abstract
Abstract An apparatus for preparing and feeding an abrasive-containing suspension into the zone of action of work tools of polishing and finishing lathes consisting of units series-connected by pipes and forming a closed circuit, comprising a unit for preparing a suspension from starting materials, a distributing unit with branch pipes for feeding the suspension to each work tool, a reservoir for collecting a waste suspension and a unit for cleaning the waste suspension. The distributing unit is formed with a pipe having a variable cross section along the length thereof. The branch pipes are located on the pipe at points of greater cross section.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
281 words
An apparatus for preparing and feeding an abrasive-containing suspension into the zone of action of a plurality of tools of polishing or finishing lathes, comprising: a unit for preparing and storing the suspension having ports for charging starting components, and having an outlet opening and a plurality of inlet openings; connecting pipes; a distributing unit formed with a pipe of a longitudinally variable cross section with sections of greater and smaller cross sectional areas, and said distributing unit having an inlet opening and an outlet opening along the direction of flow of the suspension; said distributing unit communicating through the said connection pipes connecting said inlet opening with the outlet opening of the unit for preparing and storing the suspension and through the said outlet opening connecting with one of the said inlet opening of the unit for preparing and storing the suspension; branch pipes corresponding in number to said lathes and branching off from the said pipe of variable cross section at the place of said sections of greater cross section and directed toward the said zones of action of the work tools of the said lathes; a reservoir for collecting a waste suspension located beyond the zones of action of the work tools along the direction of flow of the suspension and having an outlet; and a unit for cleaning the waste suspension, having an inlet opening and an outlet opening and said cleaning unit communicating through other connection pipes connecting said inlet opening with the said outlet opening of the reservoir for collecting the waste suspension and through the said outlet opening connecting with another of the said inlet openings of said unit for preparing and storing suspension.
