Abstract: A system for attaching optical frames and lenses is described which provides positive, reversible attachment without rims, cords, or screws. The mating is performed with a mechanical closure onto a receiving portion of the lens which has been formed as the mating piece for the closure device. Lenses may be changed and adjusted in a straightforward manner and the resulting device presents a clean, fashionable appearance without the need for structural rims, cords, or screws.

Abstract: A magnetic mounting arrangement for removably attaching auxiliary eyeglasses to an eyeglass frame. The mounting arrangement includes a male part having a projection thereon and a female part having a recess therein. The male and female parts are permanently attached to the auxiliary eyeglasses and the eyeglass frame such that the projection engages the recess when the auxiliary eyeglasses are attached to the eyeglass frame. The male and female parts can be of a magnetic or magnetizable material. The male part can include a stepped surface which mates with a stepped surface of the female part when the projection is fitted within the recess. The auxiliary eyeglasses can be various types of lenses such as sunglasses, computer glasses, fish tying readers, or magnifying glasses.

Abstract: A golf club head is provided with an impact surface formed of a shape memory alloy. The shape memory alloy is selected to have a transformation temperature applicable for the range of normal golf playing temperatures, that is in the range between about 0 and 15 degrees C. This selection of the transformation temperature of the impact surface provides an effective variation of the stiffness of the golf club head that compensates for changes of the stiffness of a golf ball with changing temperatures.

Abstract: There is disclosed an improved wide-body aircraft. The aircraft has a fuselage, a main deck and a lower deck, each deck extending substantially the entire length of the fuselage. Each of the decks is vertically spaced apart such that each of the decks is equally suitable for carrying passengers or cargo. Further, the main deck may be situated so that it is above the center line of the fuselage. There is also disclosed a method of improving the utilization of space in a wide-body aircraft.

Abstract: Eyeglass frames fabricated from shape-memory alloys which have optimized elasticity properties which exhibit a combination of shape-memory and elastic properties, which utilize the shape-memory property of these alloys in fastening elements, or which utilize the flexibility and fatigue resistance of the martensite state of the alloys as a hinge element are disclosed.

Abstract: The shape or configuration of an article made of shape-memory alloys, such as an eyeglass temple piece, or a hand held tool, is adjusted or readjusted to suit the wearer or user. While the shape-memory alloy of the article is in its martensitic state, the article may be readily deformed from its standard shape due to the alloy's low strength and malleability. The article is then confined or restrained in the customized shape so that upon heating the alloy does not return to its original austenitic or memory condition. Adequate heat is then supplied to the article to reform the austenitic state of the alloy in the desired customized shape. Preferably, the electrical resistance of the alloy is used to attain such internal heating to the resetting temperature of the article by current flow through the alloy.
