A liquid material discharge device (20) has a nozzle member (35) provided with a discharge opening (33) through which a liquid material is discharged, a switching valve (51) in communication with the nozzle member, and a discharge controller. The discharge device further includes a pressurization section (60) having a pressurization passage (62) through which the liquid material under pressurization is supplied to the switching valve, and a negative pressure section (70) including a shunt passage (72) where a pressure can be set to be relatively lower than that in the pressurization passage. The switching valve is changed over between a first position at which the discharge opening communicates with the pressurization passage and the discharge opening is cut off from the shunt passage, and a second position where the discharge opening is communicated with the shunt passage and the discharge opening is cut off from the pressurization passage.

Using standard (180, 190), as well as custom paint applicators allowing for ease of use, and with various features that allow for use with no clean up needed, such as replaceable components (121, 130, 170, 180, 190, 191, 192, 250) non-stick components (121, 130, 141), integral paint tray (130), paint containment features such as paint retaining walls (130) and paint catching recesses (130, 140). Carrying Tray (210) prevents spilling and holds replaceable parts (121, 130, 170, 180, 190, 191, 192, 250) for storage and transport. Other embodiments are described and shown.

A method for dispensing temperature-automotive body sealant includes providing a dispensing system having a pump operable to pump the sealant and a manifold receiving the sealant and operable to temperature-adjust the sealant has an elongated central body and elongated passages extending from the first end to the second end. First and second end caps are detachably connected to ends of the central body. A thermal unit is in thermal communication with the elongated central body and operable to heat or cool the elongated central body. A dispenser is in fluid communication with the manifold and operable to dispense the temperature-adjusted sealant. Sealant is pumped through the manifold and heated or cooled so as to provide a temperature-adjusted sealant. The temperature-adjusted sealant is dispensed from the dispenser.

A conveying device for conveying a pasty mass in the manufacture of insulating glass includes a carrier for a cylindrical container with pasty mass. A follow-up plate is arranged above the carrier and is vertically displaceable for placing on the pasty mass. A conveyor line is connected to the follow-up plate for further transport of the pasty mass.
