Abstract: The application of liquid to a moving fabric is effected by delivering same to a rotatable spinning disc which centrifugally impels the liquid against the fabric. This action overcomes surface tension causing the liquid droplets to break up into a fine mist so that a large area of fabric is wetted with an amount of liquid which is substantially less than the fabric weight. Also, the velocity imparted to the liquid droplets in mist forms enhances absorption of the liquid by the fabric.

Abstract: A continuous coater of the type having a conveyor extending through a coating booth where paint or other material is sprayed onto the products as they are conveyed through the booth. The booth has an air flow control vestibule located adjacent the entrance and exit ports. Each vestibule is connected to an air flow exhaust system and is so configured that it is operative to draw air almost exclusively from outside the booth into the exhaust system so that there is a minimum of input air to the exhaust system from within the booth. The incoming air from outside the booth effectively forms a flow barrier to the egress of sprayed material and/or solvent to the atmosphere through the vestibule entrance and exit ports. Preferably, there is located in each vestibule means for creating an air curtain which functions to minimize the egress of paint or solvent from the coater cabinet and to provide a more nearly saturated atmosphere inside the cabinet.

Abstract: A spread out foraminous tow of tensioned filamentary filter material is transported through a housing between an upper and a lower rotating cylindrical brush. The upper brush propels atomized liquid plasticizer against the upper side of the tow whereby a certain amount of plasticizer penetrates through the tow and is gathered in the housing within the range of bristles on the lower brush which propels the gathered plasticizer against the underside of the tow. The rate of feed of plasticizer to the upper brush is varied in response to changes in the speed of the tow, and the brushes are arrested when the transporting rolls for the tow are brought to a standstill. The lower portion of the housing constitutes a trough which surrounds the lower half of the lower brush and from which the gathered plasticizer is evacuated when the brushes are idle.

Abstract: The surfaces of a recorded disc are coated with a thin layer of lubricant by forming in an atomizer chamber droplets of the lubricant supported in air. The droplets are formed by passing a flow of air through a supply of the lubricant in the atomizer chamber at a rate and pressure such that the air causes the lubricant to be blown into the space above the supply as fine droplets. The air laden with the lubricant droplets flows out of the atomizer housing to a pair of nozzles in a coating chamber. The nozzles direct the air laden with the lubricant droplets onto the surface of the recorded disc which passes between the nozzles. Excess lubricant which does not coat the disc is collected in the coating chamber and carried back to the atomizer housing.

Abstract: A pair of horizontally disposed nozzles above a horizontally disposed seal edge surface for coating a frit slurry in a closed pattern on the surface are moved in opposite directions from an abutting, mutually blocking position until the nozzles again come into sealing abutment at a second point above the surface. During the travel of the nozzles, a frit slurry is discharged therefrom at a constant rate and is deposited in a uniform stripe on the seal edge surface. Just before the nozzles abut at the end of the coating operation, the flow of frit slurry from one of them is terminated. This permits the frit slurry from the second nozzle to make a tapered overlay of the frit slurry from the earlier cut off nozzle without forming a bump or extra width at the joint. A rectangular gear generally conforming to the shape of the seal edge surface to be coated is employed to drive the nozzles at a substantially linear speed along the seal edge surface.
