    摘要: An autoclavable diagnostic ophthalmic lens system includes a biconvex lens element having front and rear surfaces and a housing in which the biconvex lens element is mounted. The biconvex lens element is fabricated from a glass having an index-of-refraction greater of 1.7 or greater. The glass composition meets the following parameters: (% SiO2 (by weight)+% B2O3) is less than 50%; % of alkali metal compounds+% of alkaline earth metal compounds is less than 10%; and (% SiO2+% B2O3)/(% rare earth compounds) is less than 1.

    摘要: A retracting tow system is disclosed which provides a spring loaded tow rope which automatically winds the tow rope around an included spool when not in use. The tow rope is affixed to a supplied shaft in a manner which prevents damage to the retracting mechanism while in use. An offset fairlead is also supplied which reduces the force on the shaft during a tow.
