Abstract: The high spin golf club uses modified grooves for use on all types of known golf clubs, wherein the modified grooves maximizes control of the golf ball through increasing backspin. The high spin golf club's modified grooves can be used alone or in a combination with conventional grooves to tailor the properties of the club face. The modified grooves are of varied configurations and all modified grooves can be used in combination with any other modified or conventional grooves to maximize the backspin of the golf ball and tailor the spin properties of the face of the club. Further a method for making high backspin golf clubs that reduce cover damage of golf balls is disclosed.

Abstract: A novel method of manufacturing a golf ball. A golf ball made with this invention exhibits the characteristic feel and playability of a balata cover with superior durability characteristics (cut and shear resistance) which exceed those of a balata or ionomer cover.

Abstract: A novel composition useful for golf ball covers that comprises a blend of a dilsocyanate/polyol polyurethane prepolymer with a curing agent comprising a blend of slow-reacting diamine with a fast-reacting diamine such as dimethylthio 2,4-toluenediamine and diethyl 2,4-toluenediamine, respectively. A golf ball cover made with this composition exhibits the characteristic feel and playability of a balata cover with superior durability characteristics (cut and shear resistance) which exceed those of a balata or ionomer cover.

Abstract: A multi-port valve is disclosed having a ball bearing support system for a stator/rotor/valve stem assembly within a valve housing. Slipper seals or alternatively, poppet seals, connect a plurality of apertures situated in the rotor and a plurality of apertures situated in the adjoining stator so that a common central fluid receiving channel of the stator can be connected to a peripheral fluid delivery channel of the stator via a transfer channel in the rotor. The valve assembly provides a durable, virtually leak-proof system for delivery of a variety of fluids through the same delivery channel.

Abstract: A valve for controlling the rate of fluid flow therethrough by rotating a rotor about a spindle having an inlet bore in communication with an eccentrically oriented o-ring set into an eccentrically oriented slot formed in the rotor. The perimeter of the eccentric slot is modified to provide customized unique fluid flow response curves.

Abstract: A spark plug is disclosed. The spark plug has a ceramic insulator body and a center electrode that is housed at least partially in a bore in the insulator body. The center electrode is sealed off from the insulator body by at least one sealing ring surrounding the center electrode that contains material that is plastically deformable by compression.

Abstract: A dynamoelectric machine stator core for receiving a pre-formed stator winding includes a core body defining a cylindrical core main peripheral surface. A plurality of axially extending stator slots are circumferentially spaced in the core body. Each of the stator slots defines a slot first section extending radially from the slot base to a slot intermediate radial position and a slot second section extending radially from the slot intermediate radial position towards the core main peripheral surface. The slot first and second sections communicate with each other and are circumferentially offset relative to each other. The slot first and second sections are positioned, configured and sized to facilitate insertion therein of a corresponding conductor section of the stator winding with reduced needs for deforming the latter.
