Abstract: A high-speed precision positioning apparatus has a stage supported by a platen. The stage is driven by a plurality of drive motors that are co-planar with the stage and arranged symmetrically around the stage. The drive motors apply drive forces directly to the stage without any mechanical contact to the stage. The drive forces impart planar motion to the stage in at least three degrees of freedom of motion. In the remaining three degrees of freedom the motion is constrained by a plurality of fluid bearings that operate between the stage and the platen. The drive motors are configured as magnets, attached to the stage, moving in a gap formed in-between top and bottom stationary coils. Integral force cancellation is implemented by a force cancellation system that applies cancellation forces to the stage. The cancellation forces, which are co-planar with a center of gravity of the stage and any components that move with the stage, cancel forces generated by planar motion of the stage. Interferometric encoders are used as position detectors.

Abstract: A method for enhancing the brazeability of a heat exchanger manifold block (110) by promoting the braze metal flow in and around the manifold block (110) during brazing within a braze furnace. The invention is particularly directed to enhancing a brazement between a manifold block (110) and a jumper tube (124) that fluidically connects the block (110) to another component of the heat exchanger system. The method entails increasing the rate of convective and radiative heat transfer to the block (110) during brazing within a braze furnace by providing fins (116, 128), grooves (118, 130) or similar features on one or more surfaces of the block (110) that increase the surface area of the block (110), and consequently increase the heating rate of the block (110) to something closer to that of the tube (124). In effect, the surface features increase the heat transfer rate of the block (110) to compensate for the disparate thermal masses of the block (110) and tube (124). The fins (116, 128) and grooves (118, 130) have been found to promote the flow of braze metal toward the block (110), which in turn has been found to promote the quality of the resulting brazement between the block (110) and tube (124).
