  • Patent number: 5897469
    Abstract: A swing-exercise device comprises a light-weight flexible shaft having two-handed handgrips attached to each end whereby the device may be gripped and swung as a golf club. The handgrips are asymmetrically weighted such that the swing resistance varies according to which handgrip is gripped. The device is symmetrical in proportion about its longitudinal axis and an axis perpendicular to the longitudinal axis. The device may also be placed across the shoulders while the user twists at the waist or flexes the shaft by the handgrips.

  • Patent number: 4355307
    Abstract: A method and apparatus for measuring a predetermined limit of deflection or stress of a load bearing means or beam such as a walking beam of an oil well pumping unit uses a spaced fixed arm mounted on said beam at one end and having a first sensor means attached near the other end with a second sensor mounted on said beam so that said beam deflects to produce a signal which can be used to sound an alarm or operate control means to relieve stress of said beam.

  • Patent number: 4304298
    Abstract: A process for cementing adjacent a subterranean gas-containing zone, in which process a cement slurry containing a stabilized, dispersed gas is placed adjacent the zone. Sufficient gas is present in the cement slurry or is capable of being generated within the slurry to prevent the connate formation gas under pressure from passing into or around the cement prior to the time the cement has set up.
