  • Patent number: 4346534
    Abstract: An apparatus for abrading and finishing the inner surface of an unusual shape, for example the inner ring of a gerotor device, with a tool holder adapted to carry honing stones for movement along the part surface and driven by a mating part engaging a stationary ring mounted inside the assembly and affixed to the drive spindle housing. The stationary ring has an identical shape to the workpiece being machined to guide and synchronize the tool holder in an eccentric path during the abrading operation and the workpiece and stationary ring are orientated to maintain the synchronous relationship. The apparatus while being rotated is also reciprocated transversely to the workpiece surface causing the stones to move in a helical path.

  • Patent number: 4346481
    Abstract: A baseball mitt comprising front and back plies forming a mitt body having thumb portion, a finger portion and a portion connecting the thumb and finger portions, and a glove secured to the back of the body with the front of the glove facing the back ply. The glove has a thumb stall disposed generally behind the thumb portion of the body, at least one finger stall disposed generally behind the finger portion of the body, a crotch portion between the thumb and finger stalls, a palm portion, and a hand-receiving opening adjacent the bottom of the mitt. The glove is joined to the mitt body at the periphery of the hand-receiving opening and at the ends of the thumb and finger stalls, but is free of attachment to the body at its palm portion, thereby providing freedom of movement of the palm portion of the glove relative to the mitt body for increasing the flexibility of the mitt.

  • Patent number: 4345592
    Abstract: A pressure demand breathing apparatus having a facemask connected through a pressure demand regulator with a shut-off device that operates automatically to interrupt the supply of air to the mask when the facemask is removed.

  • Patent number: 4345593
    Abstract: A face mask is connected to a source of breathing fluid through a pressure-demand regulator and a supply line. The regulator admits breathing fluid to the mask on demand and maintains a positive pressure within the mask at all times to prevent inflow from the surrounding atmosphere. The regulator has a flow capacity considerably greater than that normally required, even when gasping or breathing heavily. An automatic shut-off device in the supply line upstream of the regulator permits the peak flow of a predetermined breathing requirement but is responsive to abnormal flow conditions, as for example where the mask is removed from the wearer, to close the supply line and thereby prevent wasting of the air breathing fluid supply. The apparatus can be manually reset to normal operation and will reset itself after the mask is repositioned on the wearer.

  • Patent number: 4340222
    Abstract: A tennis ball consisting of two identical hemispheres joined together and including small upstanding integral fingers molded into the outer surface of the ball to provide surface texture, and enable the ball to grip the surface of the racquet. Each hemisphere incorporates an integrally molded plug in the interior of the hemisphere for providing means for introducing pressure into the ball. One or both of the plugs are pierced by a needle during fabrication to provide a conduit for a needle valve inflating device. A cylindrical sphincter is placed around the inflation plug during manufacture to squeeze the plug and prevent the escape of air when the ball is inflated. The ball is manufactured by first injection molding the hemispheres and then placing the hemispheres in facing mold halves.

  • Patent number: 4339700
    Abstract: An apparatus for accurately controlling the rotary position of a high speed position control servo system having a servo motor which is fed by a conventional servo amplifier and drive amplifier means with a tachometer feedback to the drive amplifier. Incorporated in the system is a high frequency quadrature phasing network which receives timing signals from the servo amplifier and conditions these signals into a balanced sine cosine function which excites a rotary position transducer that is directly coupled to the motor. The high frequency sine cosine signal produces a reference feedback signal which is the difference between the actual rotor position of the motor and the sine cosine field of the position transducer stator. The error signal is fed back to the servo amplifier and is conditioned through a transformer, pre-amp and filter means and then fed into the servo amplifier means to tract the servo motor.
