  • Iodothyronine polymers
    Patent number: 5910569
    Abstract: Iodothyronine polymers having a plurality of recurring units of formula I ##STR1## in which A is iodo and B, C and D are independently H or iodo are described. Polymers in which A and C are iodo and B and D are independently H or iodo and in which substantially all of the recurring units are L-stereoisomers, have utility in treating thyroid hormone deficiencies.

  • Apparatus for centering a wheel on a hub
    Patent number: 5692811
    Abstract: A centering apparatus for centering a detachable vehicular wheel with a central opening on a hub. The one-piece centering apparatus fits in an annular groove in the hub pilot boss. The one-piece centering apparatus may be in the shape of a ring, with bendable and resilient fingers extending outwardly from the ring at an angle away from the outer end of the pilot boss. As the wheel is mounted over the hub pilot boss, a flange at the wheel central opening presses against the fingers on the ring. This causes the fingers to bend slightly to compensate for any interference fit. The resilient action of the fingers keeps the wheel centered on the hub. The wheel is then bolted to the wheel assembly. In other embodiments, the centering apparatus has a cross-section in the approximate shape of a "V", "U", "N", or "M", one leg of which serves as the bendable and resilient finger. The fingers may be replaced by a continuous member extending around the circumference of the pilot boss.
