  • Patent number: 10556162
    Abstract: A club 2 includes a head 4, a shaft 6 and a grip 8. A club length L1 is 45 inches or greater and 48 inches or less. A ratio (Wh/Wc) of a head weight Wh to a club weight Wc is equal to or greater than 0.71. A moment of inertia Ix about an axis of a swing is equal to or less than 6.90×103 (kg·cm2). However, when the club weight is defined as Wc (kg); an axial-directional distance between a grip end and a center of gravity of the club is defined as Lc (cm); and a moment of inertia about the center of gravity of the club is defined as Ic (kg·cm2), the moment of inertia Ix (kg·cm2) is calculated by the following formula (1).

    Abstract: Coupling agents useful for preparing vulcanized composition with filers such as silica and carbon black are provided. The coupling agents include fluorine substituted styrene compounds and styrene compounds containing a hydrocarbyloxysilane functional group. The coupling agents may be grafted onto polydiene polymers or added into a vulcanizable composition as an oligomer. The use of one or both of fluorine substituted styrene compounds and styrene compounds containing a hydrocarbyloxysilane functional group may improve the strength, rolling resistance, and/or cure rate of a vulcanized polymer compared to a vulcanized polymer without a coupling agent.

  • Patent number: 10449569
    Abstract: Methods, processes, compositions and systems for preventing leaching effects from water pipes (such as lead, steel and copper) having an inner diameter of at least approximately 12 mm. 2-part thermoset resin coating is applied to the inner surfaces of the pipes where the curing agent can be a phenol free and plasticizer free adduct type. The coating can reduce heavy metals, such as lead, from leaching from installed pipes to less than approximately 10 ?g/L (10 ppb). When cured, specific leachates, Bisphenol A and Epichlorohydrin from the coatings will be (less than) <1 ?g/L (1 ppb) with overall TOC levels measured at (less than) <2.5 mg/L (2.5 ppm). Pipes can be returned to service within approximately 24 hours, and preferably within approximately 4 hours. The methods, processes, compositions and systems can work with non-metallic pipes having metal valves and/or metal fittings.

  • Patent number: 10406415
    Abstract: An improved golf club head cover and hands-free method of use allow a user to hold a golf club normally by the handle with one or two hands while standing substantially upright and slide the golf club head into and out of the head cover while the head cover is sitting on the ground, without the user needing to bend down or touch the head cover. A rigid cover may include a concave main body pivotally connected with one or more rotating components that include tabs that close the rotating components around the golf club head and shaft when the club is inserted securely into the cover. Magnetically attractive and repulsive structures may be included to assist with keeping the cover shut and holding it open. Traction structures are provided to laterally engage grass-covered ground to resist lateral movement during hands-free use.
