Abstract: Disclosed is a method for dislodging a mold from a casting formed within the mold. The mold may be removed from the casting by scoring the mold and applying a force sufficient to cause the mold to fracture and break into pieces. Additionally, the mold may be fractured by either explosive charges placed in the mold pack or by high energy pulsations directed at the mold. Once the mold is fractured and broken into various pieces it may then be dislodged from the casting.

Granted: 2006-07-11
Abstract: To prevent the entry of ambient air and liquid such as rainwater into a direct acting type auto-by starter and thereby prevent the formation of rust in the auto-by starter, by adjusting pressure fluctuations in the auto-by starter caused by the operation of a starting valve for opening and closing a starting intake passage. A starting valve 2 is lifted by upwardly operating a manual lever 7, thereby opening a starting intake passage 1c to start an internal combustion engine. A pressure in a sliding space 2f for the starting valve 2 is increased by the lift of the starting valve 2, so that the gas in the sliding space 2f flows out of the sliding space 2f. The flow of the gas is absorbed by an increase in volume inside a bellows boot 5 mounted on an upper portion 2b of the starting valve 2. When the starting valve 2 is lowered by the operation of a spring member 6, the pressure in the sliding space 2f is reduced to allow the gas flow from the bellows boot 5 into the sliding space 2f. This gas flow is absorbed by a decrease in volume inside the bellows boot 5, thereby preventing the entry of ambient air and water into the auto-by starter 10.
