Patent number: 6640958Abstract: A chain-free conveying device for persons has directly driven step bodies which run forward in one direction one after the other and run back more quickly thereunder. Each step body runs on rollers, of which two may each be driven by a respective electric motor. Each step body includes a device for the supplying of electrical current to the step body. Each step body has at least one sensor for determining spacing from the adjacent step bodies. A control electronic system controls the electric motors in dependence on a signal from the sensors, so that the step bodies run directly one after the other in a person transport region. A respective tipping station for inclining the step bodies is provided at each of the ends of the conveying device. In preferred embodiments the step bodies are directly driven by a friction wheel drive or by means of toothed wheels.Type: GrantFiled: May 16, 2002Date of Patent: November 4, 2003Assignee: Inventio AGInventor: Leopold Postlmayr

Patent number: 6532405Abstract: An exemplary embodiment of the invention is a method for detecting a potentially locked axle on a vehicle propelled by an AC motor. The method includes conducting a speed test by estimating axle speed and comparing estimated axle speed to measured vehicle speed. The existence of a potential locked axle condition is determined based on the comparing of estimated axle speed to measured vehicle speed. Additional tests are disclosed for determining a potential locked axle condition and a sensor fault condition.Type: GrantFiled: August 9, 2000Date of Patent: March 11, 2003Assignee: General Electric CompanyInventors: Ajith Kuttannair Kumar, Jeffrey Louis Daigle

Patent number: 6418855Abstract: An industrial truck (1) is driven by a friction drive (7) acting on a rail (6). For this purpose, the industrial truck (1) stands on the underlying surface by way of a front steering-roller pair (3) and a rear fixed-roller pair (5) and is kept on track by a guide roller (9) butting against the rail (6). In the region of a curved element (12), the rail (6) has an elevation, with result that there is an increase there in the propulsion force which can be transmitted by a friction wheel (8) of the friction drive (7). An introduction aid (11) allows the guide roller (9) to be aligned without difficulty in relation to the rail (6). The industrial truck (1), rather than being bound to fixed cyclic operation by its friction drive (7), can be specifically accelerated or decelerated. In the event of malfunctioning of the industrial truck (1), the latter can easily be moved manually.Type: GrantFiled: October 16, 2000Date of Patent: July 16, 2002Assignee: Mannesmann VDO AGInventor: Dirk Fischer
