Patent number: 6223756Abstract: An apparatus for degreasing solid and/or mass-produced parts, such as small metallic parts comprises a drum with a perforated drum wall rotatable and drivable around a vertical axis. A charge opening is furnished at the top and a discharge opening furnished at the bottom. The discharge opening is closable by an axially movable floor closure. A stationery outer ring channel surrounds the drum and exhibits at the bottom an outer ring trough with discharge port. An inner ring channel is disposed between the outer ring channel and the drum and axially adjustable by way of an adjustment member and including an inner ring trough at the bottom. Feed lines for treatment agent lead into the drum. The inner ring channel is formed adjustable from the starting position, releasing the drum perforations, into a center position covering the drum perforations on the outside, and into a sealing position for sealing the drum.Type: GrantFiled: March 31, 1999Date of Patent: May 1, 2001Assignee: Turbo-Clean GmbHInventor: Heinz Schulze-Eyssing

Patent number: 6168715Abstract: The invention concerns a device for the oil treatment of sintered parts consisting of a drum (11, 111) which is mounted so that it can rotate about a vertical axis and which can be driven. It has a drum mantle (11′, 111′) and loading and unloading devices so that it can be loaded and unloaded axially, a floor that tightly closes the opening in the floor (19, 119) against the-drum mantle (11′, 111′), connections (28, 29, 30, 31/128, 129, 130, 131) leading into the drum (11, 111) for liquid and gaseous treatment media for carrying out the treatment phases, and outlets (35, 135) for letting treatment fluids out of the drum (11, 111). The task of the invention is to create a device that not only mechanizes the treatment process but also can be repeated many times, always in the same way.Type: GrantFiled: October 14, 1997Date of Patent: January 2, 2001Assignee: Turbo-Clean GmbHInventor: Heinz Schulze-Eyssing

Patent number: 4573952Abstract: A belt tensioning installation with a control device for the belt tension, which serves to monitor the tension of a belt, especially of a toothed belt, in order to prevent the relative position between driving and driven toothed belt pulley as a result of an excessive decrease of the belt tension. For that purpose an electric contact place is formed on a pressure element by way of which a tensioning roller is pressed against the toothed belt; the contact place is opened by spring force in case of a non-permissively reduced belt tension. An energizing circuit which includes the contact place is thereby interrupted and an optical or acoustic warning signal is triggered at an indicating apparatus by way of a relay.Type: GrantFiled: February 1, 1984Date of Patent: March 4, 1986Assignee: Dr. Ing. h.c.F.

Patent number: 4383054Abstract: A self curing aqueous solution/dispersion comprising about 50-70 wt. % water, about 25-35 wt. % of a novel N-polymethylene substituted polyoxypropylene polyamine and about 3-9 wt. % of a curable polymer-forming component such as an epoxy-resin is described. The solution is useful for injection into permeable earth formations such as unconsolidated sands to reduce their permeability and consolidate the formation. Novel N-substituted polyamines of the formula [NaO.sub.3 S--R.sub.1 ].sub.m A wherein R.sub.1 is a C.sub.2 to C.sub.6 polymethylene group and A is a polyoxyalkylene polyamine are employed in the solution to render the epoxy-resin component adequately soluble or dispersible in the aqueous solution and to act as the curing agent for the resin.Type: GrantFiled: May 28, 1981Date of Patent: May 10, 1983Assignee: Texaco Inc.Inventors: Heinz Schulze, Harold G.
