Patent number: 5693150Abstract: A paint gun cleaner includes a spray unit mounted in an enclosure in spaced relation to an opening in the enclosure through which the paint gun to be cleaned is inserted. A ring shaped spray unit combines a solvent dispenser, which may be either a solvent knife generating a curtain of solvent in the central opening of the spray unit or a plurality of nozzles directing solvent onto the paint gun, with an air knife positioned between the solvent dispenser and the enclosure opening. The air knife directs air flow radially and axially inward to prevent escape of solvent, and to recirculate air mixed with solvent around the sides of the spray unit and through the space between the spray unit and enclosure opening to reduce the amount of ambient air which is drawn into and which must be separated from the solvent and dissolved paint before discharge.Type: GrantFiled: May 3, 1996Date of Patent: December 2, 1997Assignee: AEG Automation Systems CorporationInventor: Thomas M.

Patent number: 5673165Abstract: A reduction in contact bounce in an electromagnetic switch is accomplished by optimizing armature speed over its travel path with a circuit arrangement for controlling a drive current in the coil of the electromagnetic switch. A superposed speed loop including a speed sensor produces a measured voltage in response to speed of the armature. A converter coupled to the speed sensor converts the measured voltage into a value corresponding to an actual speed of the armature. A first summer receives a constant reference value corresponding to a desired speed for the armature and the value corresponding to the actual speed of the armature, and produces a difference voltage corresponding to a difference between the desired speed and the actual speed of the armature. A proportional element amplifies the difference voltage and produces a desired current value corresponding to the amplified difference voltage.Type: GrantFiled: August 18, 1995Date of Patent: September 30, 1997Assignee: AEG Niederspannungstechnik GmbHInventors: Olaf Kuhn, Thomas Roschke

Patent number: 5530310Abstract: For a squirrel-cage rotor of an electric machine, having a cage that passes through the stack axially and is made of electrically well-conductive short-circuit rods that are connected by short-circuit rings at the ends projecting from the stack, oscillation problems that result during operation with frequency converters are intended to be solved. In addition, higher natural torsion frequencies are intended to be achieved on the rotor, that is, the construction is to be made less sensitive by simple modifications to the squirrel cage in order to prevent the resonance effects. This object is attained in that respectively two, three or more short-circuit rods are guided together to rod assemblies at their ends, and these are connected to the short-circuit rings with material-to-material bonding.Type: GrantFiled: September 2, 1994Date of Patent: June 25, 1996Assignees: AEG Schienenfahrzeuge GmbH, Siemens AktiengesellschaftInventors: Bernd Sauer, Heinz Boehm, Egbert Scharstein
