A hoisting assembly that is adapted to be mounted to the frame of a vehicle where a hoisting device extends an attachment member such as a hook to connect to an engagement location of the differential where the hoisting assembly is positioned substantially vertically above the differential and when the hoisting assembly supports a differential the load is transferred to the frame of the vehicle. An insulating member is positioned around a portion of the terminal. The shield includes at least one open slot formed therethrough for providing a passageway through which gas and air can flow, thereby forming one or more open spiral patterns in the tubular shield. The data latches can latch the data bits with a latch signal to satisfy memory access timing requirements and a data write clock signal to satisfy output timing requirements. In combination these traits set \u2018YASAL\u2019 apart from all others existing varieties of Jamesbrittenia known to the inventor. The temperature of the burnt gas produced by the burner is increased according to the elapsed time from the beginning of the startup processing.
