Abstract: The invention is directed to a system and method of applying a coating of lubricant material to the surface of a sheet metal blank in a controlled manner such that some areas of the blank have uniform thickness of lubricant while other areas have no lubricant at all or have a variable amount (progressively increasing or decreasing) of lubricant.

Abstract: Various fluoropolymers have been proposed for imparting oil and water repellency to leather. Commonly, these fluoropolymers are amphiphilic; i.e., they are made from at least one monomer which is hydrophobic and at least one monomer which is hydrophilic. The present invention identifies and remedies disadvantages associated with the ability of amphiphilic fluoropolymers to impart oil and water repellency to leather. Contrary to conventional thinking, it has now been discovered that the incorporation of hydrophilic groups in a fluoropolymer undesirably reduces its ability to impart water resistance to leather. Correspondingly, it has also been discovered that a fluoropolymer incorporating fewer or no hydrophilic groups imparts superior oil and water repellency to leather when compared to fluoropolymers incorporating more hydrophilic groups. Therefore, this invention provides fluoropolymers which incorporate reduced levels of hydrophilic groups.

Then, the developer is spouted onto the rotating wafer to spread the developer on the surface of the wafer.

Abstract: An improved technique achieves a uniform photoresist film on a wafer by controlling the volatility of the solvent in a photoresist solution during the bake process step. Because film formation takes place in the bake rather than the spin steps of the process, the improved technique involves using less viscous and therefore less costly and easier to use resists to cast relatively thick photoresist films. Such control is achieved in an enclosed chamber into which a carrier gas is introduced; the carrier gas mixes with gaseous solvent to create a saturating atmosphere in which the rate of evaporation of solvent decreases. This enables the heating of the wafer without the reduction of solvent in the film so that the photoresist can self-level. When the film has self-leveled, the solvent is then baked off as usual.

An initial layer of the coating material may be deposited on a complex surface of the part using dipping, spraying, spin coating, or other like techniques. The coating material is redistributed by simultaneous rotation and vibration of the part using specifically selected process conditions, such as orientation of vibrational and rotational axes relative to the part, rotational speeds, and vibrational frequencies and amplitudes.

Abstract: Brominated butadiene polymers are recovered from solution and formed into particles by spraying the solution onto a heated, mechanically agitated bed of seed particles.

The process forms at most small amounts of agglomerates and fines.
