Abstract: Disclosed is a system and method for suppressing rotor noise by distributing mass and momentum sources and sinks on the rotor blade. A source is located on the blade, and therefore has the directivity of moving, as opposed to a stationary source. Moreover, the motion of the blade with respect to the observer amplifies the sound from the source in a manner similar to the manner in which motion of the blade amplifies all other sources of noise associated with the rotating blade. Two sources can be used to cancel noise. The first source, created by ejecting air from or drawing air into the blade, is used to cancel the "load" portion of rotor noise. The second source, created by developing a radial force with a proplet, is used to cancel the "thickness" portion of rotor noise. More control can be achieved by time modulating the rate of suction or the amplitude of radial force developed by said proplet.

A plurality of sealing members disposed concentrically with the bearing means are interposed between the rotary shaft and an inner surface of the cylindrical support portion at a location axially outwardly spaced from the mechanical seal, and a grease is filled between the sealing members. The water pump structure not only improves the sealing property of the sealing members by providing the sealing members at a location in which the deflection of the rotary shaft is smallest, but also increases the retaining property for the grease between the plurality of sealing members.

Abstract: An innovative teaching process for instruction of the proper placement of the hands on the grip of a golf club using a sequence of golf grips of increasingly greater numbers of flat, longitudinal surfaces incorporates successively less detectable, yet consistently located tactile feedback producing ribs on the golf grip. Teaching starts with a maximum biomechanical feedback grip with ribs that are pronounced. As the golfer develops sufficient proficiency with locating the hands on the grip and maintaining this proper hand positioning through the swing, the maximum biomechanical feedback grip is replaced with a new grip with less pronounced ribs, typically, with the same spacing as the first used grip. This process is repeated until the golfer has advanced from a maximum feedback grip to a minimum biomechanical feedback grip, i.e., to a substantially circular grip as accepted for USGA golf play. In one form, the grip, generally circular in nature, has from five to nine internal ribs.
