Abstract: A method for core pulling and insertion in synchronization with the opening and closing of the mold in a cavity including a fixing half and a moving half, or a fixing half, a moving half and several cavity plates installed between fixing half and moving half as well as the core moving reciprocally inside the cavity, wherein a downward movement of a transmission gear is coupled with an opening of the mold, synchronous with a pulling of the core out of the cavity, and an upward movement of the transmission gear is coupled with a closing of the mold, synchronous with an insertion of the core into the cavity.

Abstract: A method for core pulling and insertion in synchronization with the opening and closing of the mold which is used in a cavity constituted by a fixing half and a moving half, or a cavity constituted by a fixing half, a fixing half and several cavity plates installed between fixing half and fixing half as well as the cores moving reciprocally inside the cavity, wherein it is characterized to be completed step by step.

Abstract: A particle removal system provides for the removal of submicron particles in gas streams, such as combustion flue gases or diesel exhausts. The gas stream is treated to permit very fine particles to coagulate through a short residence time in the conduits handling the gas stream, and thereafter is conditioned to establish saturation of the gas stream at a low temperature, such as by water injection. The saturated stream of gas containing the particles is then passed through a particle growth chamber or section where steam is injected into the gas to establish a supersaturation condition, causing the particles in the gas stream to grow in size by water condensing around the particles. The particles are grown to a size that is near one micron, and are removed through conventional particulate removal devices.
