  • Patent number: 6059672
    Abstract: An instructional device for the game of golf has housing containing therein; a micro processor, a visual display means visible from outside the housing, data input means connected to the microprocessor and a plurality of sensing means whereby the information input as data and the sensed information are processes by said micro processor to give an indication of the type of golf shot which should be taken to advance play of the game of golf.

  • Patent number: 5941779
    Abstract: A device for improving the performance of a golfer, particularly the repetitive correct swinging of the club, is preferably mounted on a standard golf club shaft, in place of a conventional head, but alternatively could be made to be temporarily attached to the head or shaft of any standard golf club. The subject device has a housing containing two directional gyros, a power source, a set of sensors, and a like set of alarms responsive to the sensors to give an audible and/or tactile alarm when the golfer's swing is outside that of each directional gyro's predetermined and set rotating direction.

  • Patent number: 5810048
    Abstract: A metal face sealing coupler providing high elasticity and/or spring back to maintain effective annular sealing between male and female coupling members while allowing and lateral movement for make up of the two coupling members. The female member has a main body with an internal poppet valve and a metal face seal with high deflection and spring back capability, generally an E-ring. An outer shell is attached to the main body and provides lateral support for the metal sealing element, lateral guidance and vertical connection to a support ring and lateral guidance and indexing of the female member during make up with the male member. The support ring allows the main body a limited lateral movement when the female member makes up with the male member. The female member fits inside the outer shell. The male member, with an internal poppet valve, engages the metal face sealing element, which flexes and allows for sealing in any position within a pre defined longitudinal tolerance envelope.

  • Patent number: 5080400
    Abstract: A hub clamp will be used to connect two conduits together in end-to-end relationship. Each conduit has a pair of generally parallel load shoulders that extend around the conduit and are axially spaced from each other. The clamp has two sets of load shoulders, one for engaging each set of load shoulders on each end of the conduit. The clamp is in two halves, and when bolted together, draws the ends of the conduits toward each other. Each load shoulder is separated by a flank. The two flanks of the mating load shoulders are separated by a gap when fully made up. The first load shoulder of each conduit has multiple angled sections. The lead section is at a greater angle than the load section relative to a plane perpendicular to the longitudinal axis of the conduit. The clamp will be mounted releasably to an upper conduit so that it can slide inward and outward, for vertical conduit applications.
