Abstract: A jar candle includes a jar, a lid connected to the jar of the jar candle for articulation between an open position and a closed position, and an arrangement for controlling a flame of the jar candle. The arrangement includes an electromagnet carried in a housing fixed to the jar, a permanent magnet carried by the lid, and a power source for powering the electromagnet. The electromagnet cooperates with the permanent magnet to retain the lid in the open position when the power source powers the electromagnet and further cooperates with the electromagnet to repel the electromagnet and thereby articular the lid to the closed position.

Abstract: An arrangement for controlling a flame of a candle includes a lid mounted to the jar of the jar candle for articulation between an open position and a closed position. The arrangement further includes an electromagnet, a permanent magnet and a power source. The electromagnet is carried in a housing fixed to the jar. The permanent magnet is carried by the lid. The power source provides powering the electromagnet. The electromagnet cooperates with the permanent magnet to retain the lid in the open position when the power source powers the electromagnet and allow the lid to articulate to the closed position when the power source is disconnected from the electromagnet.

Abstract: A blade lift and support system for a road grader is taught which is of simplified construction and improved geometry. According to one embodiment, the adjustment of the beam and associated grader blade is fully hydraulically controlled including locking of the beam in a desired position and maintaining the beam position by an hydraulic fluid lock. This preferred arrangement permits full power adjustment of the high-lift while the blade is in a lifted condition. The particular beam shape improves the position of the cylinders to effect positioning the blade for working.
