Abstract: A twin tower gas drying system is disclosed for cleaning compressed air lines in locomotives, buses, transit vehicles and the like by removing undesirable contaminants from an air or gas stream. A multistage filtration process employs a first scrubber that is capable of removing particulate material or soot from a stream of unpurified gas.

Abstract: An evaporator comprises a base with a vacuum connection. A tray is fixed to the base, and has seating positions in which to seat pans which hold sample liquid. A transparent cover is attached to the base with a hinge. The cover fits over the tray and when closed forms a tight fit with the base and is in close proximity to the pans. The cover has inlets angled down at about 37° to 42° over each pan seating position such that when a vacuum source is connected to the vacuum connection, air from outside the evaporator is drawn in through the inlets and aimed toward the sample liquid in each pan such that the solvent evaporates. Pans are preferably commercially available pans which are about 70 mm in diameter and about 16 mm in height, and tapered outwardly towards the top. Preferably, the cover has two inlets for each pan, aimed in opposite directions, and on opposite sides of each pan, such that when air strikes the sample liquid it induces a swirling motion.

Abstract: A processing unit for a substrate has a vertical thermal processing furnace 4 having a bottom and an opening provided at the bottom. A boat holding substrates in vertical multistairs can be placed on a first lid, and the first lid can open and close the opening of the vertical thermal processing furnace with the boat placed thereon.

This eliminates the necessity of providing a container for the drying agent.

Abstract: A flux vapor management system for a reflow oven includes temperature control units disposed in heating and cooling regions of the oven. A fan within each of the temperature control units provides suction to an intake port. Intake ports of selected temperature control units in the heating region of the oven are connected with a barrier vent disposed between the heating and cooling regions of the oven. Gas drawn into the barrier vent by the suction from the intake ports prevents flux laden gas from migrating into the cooling region. The flux vapor management system also includes a filter for removing flux vapors from a reflow oven. The filter condenses flux vapors by converging a jet of hot gas from the oven with a cooled gas jet causing the flux vapors to condense while suspended in the gas stream. The flux laden gas does not contact any solid surface below the flux condensation temperature so there is no build-up of flux within the apparatus.
