Abstract: A compressor wheel that can be employed in devices such as turbochargers. The compressor wheel includes an axially extending hub having an inlet end, a shaft bore extending from the inlet end and an arcuate outer surface opposed to the shaft bore. The axially extending hub is composed of a metal and has a porous region located proximate to the arcuate outer surface of the axially extending hub. The compressor wheel also includes a blade array disposed on the arcuate outer surface of the axially extending hub. The blade array has an outer surface and an inner region. The blade array comprises a plurality of circumferentially-spaced, radially and axially extending blades disposed thereon and is composed, at least in part of a polymeric material. Polymeric material located in the inner region of the blade array extends into the porous region defined in the axially extending hub.

Abstract: The present invention relates in general to golf training devices and, more specifically, to a portable putting trainer suitable for indoor or outdoor use. Unlike other putting training devices, the trainer of the invention provides feedback to the user concerning the speed of the putt, its direction, and the distance it would have traveled past the hole if not holed, collects, sorts and retains putted balls according to direction and predetermined distance ranges, and particularly trains the user to strike the ball on the proper line with such force as to impart an initial speed sufficient to at least cover the distance to the hole with a safe speed margin in reserve, and preferably with the optimum speed. It accomplishes this by means of a target, a ramp, and one or more troughs and stalls constructed to identify, sort and retain balls according to direction and predetermined distance ranges.
