Patent number: 4722476Abstract: An apparatus for positioning an automobile in an extremely limited area such as that in a parking lot. The apparatus has a pair of carriages for carrying left and right wheels of the vehicle and movable in the breadthwise direction of the vehicle, a pair of guide bars having inclined portions for progressively engaging the inner or outer surfaces of the vehicle wheels as the vehicle moves onto the apparatus, a spring for urging the guide bars to standard positions where the guide bars are in symmetry with each other with respect to the longitudinal axis of the limited area, and a racks-and-pinion mechanism which is arranged such that, when one of the guide bars is displaced by the vehicle wheel in the breadthwise direction of the vehicle, the other guide bar also is moved in such a manner that both guide bars are always maintained in symmetry with each other with respect to the axis of the limited area.Type: GrantFiled: August 27, 1986Date of Patent: February 2, 1988Assignee: Kabushiki Kaisha ShinseiInventor: Yoshisada Inaba

Patent number: 4719861Abstract: Single-sided linear induction motors (SLIMs) suspended in proximity to the rail of a locomotive are energized to increase the effective adhesion between the locomotive drive wheels and the rail in response to the detection of an operating condition in which the tractive effort of the locomotive traction motors is limited by less than optimal adhesion. The SLIMs are energized in relation to the reserve power capability of the power source and the limit of tractive effort improvement. One method further employs sand dispensing units activated if the suboptimal operating condition is not alleviated by activation of the SLIMs. Another method uses the sand dispensing units first, and only activates the SLIMs if the suboptimal operating condition is not alleviated by activation of the sand dispensing mechanism.Type: GrantFiled: October 23, 1986Date of Patent: January 19, 1988Assignee: General Motors CorporationInventors: Jack W. Savage, Thomas J. Savage, Mark A. Navarre
