摘要:
An electronic voting system (20) includes a central judges station (22) having a detachable flash memory cartridge (42) for use in storing election data. The data contents of the memory cartridge (42) are shadowed by identical storage in a separate flash memory module (74). The memory cartridge (42) is retained by a password-protected solenoid lock mechanism (44) to preserve the integrity of election results. The station (22) is networked to a plurality of voting booths (24 and 26) that provide ballot selections to the judges' station (22).
摘要:
A shift mechanism (66, 68, 70, 72) for shifting a member (22, 22A', 22B, 27C) for performing an operation at a preselected one of at least two spaced-apart operating positions. The mechanism comprises a threaded screw (10, 10A, 10B, 10C) that is rotated about its central longitudinal rotational axis ("C") by a motor (14, 14A, 14B, 14C) to move a drive nut (12, 12A, 12B, 12C) in opposite axial directions therealong relative the particular direction the shaft is rotating and causes the drive nut to compress a resilient biasing means (20, 20', 20A, 20A', 20B, 20B', 20C, 20C') which is adapted to urge the member (22, 22A', 22B, 27C) to the particular position in a preloaded condition such that the operation is able to be performed by overcoming any resistance incurred in performing the operation or upon removal of the resistance upon the occurance of an event enabling the operation to occur.
摘要:
An axle lubrication system is provided utilizing an especially configured differential carrier housing adapted to be mounted to an axle housing with the axle housing oriented either upside-down or right-side-up. In either orientation, the lubrication system of the present invention provides a positive lubrication flow to the differential in either a forward or reverse direction of operation. The differential bearing support defines first and second lubricant passages and a differential carrier housing defines first and second lubricant troughs, communicating, respectively, with the first and second lubricant passages. Each of the lubricant troughs has an opening adjacent the pinion gear such that the first lubricant trough receives splash from the pinion gear, for either direction of rotation of the pinion gear, with the axle mechanism in the right-side-up position and the second lubricant trough receives the splash from the pinion gear, in either direction of rotation, with the axle mechanism in the upside-down position. Thus, the use of pick up director members is eliminated and positive lubricant flow, independent of lubricant temperature, is provided in all four modes of operation.
