Abstract: Occurrence of mechanical noise and tape damage due to operation of a pinch roller is avoided when the system is switched from the tape playback mode to the radio mode or vice versa. On playback of the tape, an interrupt signal 33 from a microcomputer 34 is low. Transistors 28 and 13 are thus turned on. A drive motor 14 in the tape deck 11 is energized by power from a (+B) terminal 45. When the cassette tape is loaded into the tape deck, a plunger 15 is energized directly by power from a (TAPE+B) terminal 12. Thus, a pinch roller 41 in a head drive mechanism 16 is brought into contact with the tape 43. If the microcomputer 34 detects any interrupt signal such as traffic or emergency information signals multiplexed with FM broadcasting waves, it changes the interrupt signal to high so that the transistors 28 and 13 are turned off. Therefore, the drive motor 14 is de-energized, but the power continues to be supplied to the plunger 15.

Abstract: Individual lenses of subsidiary glasses, such as sun glasses, are attached to lenses of ordinary glasses by means of three fasteners, each in the shape of a square arch, made of synthetic resin and each provided, at about the middle of the arch, with an inner projection to form front and rear fitting portions at the front and rear sides of the projections respectively. The three fasteners are fitted respectively, with the front fitting portions, in three grooves provided in the periphery of the subsidiary lens and secured in place. The grooves are located so that lines connecting them form a triangle, with the distance between upper and lower fasteners located near the bridge of the ordinary glasses being larger than the outside diameter, in a vertical direction, of the ordinary glasses. This permits the lens of the subsidiary glasses to be fitted and removed from the lens of ordinary glasses in a direction transverse thereto.

Abstract: An eyeglass construction characterized by having a conventional frame with a pair of rim supports for receiving and holding a pair of lenses. The rim supports have a plurality of fixed prongs distributed around the rims at points that are remote from a bridge that connects the tops of the two rim supports. Affixed to the frame, usually near the bridge, is a retaining mechanism that includes a housing having two open ends. A wire-like member is adapted to protrude out of each of the two open ends of the housing for a distance which is adequate to cooperate with the fixed prongs for firmly holding the lenses in the rim supports. Whenever it is desired (or necessary) to replace one or both of the lenses, the appropriate wire-like member is retracted into the housing, such that the adjacent lens may be manipulated--usually by slightly rotating it--in order to free it from the rim support. The wire-like retaining member is biased in its extended position by a bias member having the characteristics of a spring.

The support rib is discontinuous between the lower end the upper end of its rim adjacent the bridge. The eyeglasses further include a retainer preferably formed as a one-piece molded plastic part which is releasably held by the front and has a component received in the opening. The retainer overlaps both lenses and cooperates with the abutment surface of the rims to capture the lenses.

Abstract: A sight-corrective lens is attached between an eyepiece of a respirator and the eye of the wearer by a monocular mount into which the lens fits as if into a standard spectacle frame. Attachment devices for the mount are apertured lugs on a surround of the eyepiece and tabs on the mount. By making the tab and mount in one position of different tangential width from the tab and mount in the other, a desired unique positioning of the lens is assured. The mount may have a seal ring of which the deformable ridge is pretensioned against the eyepiece by the fitting of the tabs in the lugs to prevent ingress of moisture or particles between them.

Adjustment and tightening of the tension of the thread to hold the lens on the eyeglasses is accomplished by a tensioning device carried on the eyeglasses. The tension of the thread is lessened to allow lens replacement or is increased to hold the lens in position with operation of the tensioning device.

Abstract: There is disclosed a frame front for eyeglasses permitting interchanging of lenses without any tool. The frame front comprises a main bridge member connecting lens supports and a median bridge member extending between the lens supports but disconnected therefrom. The median bridge member has retaining notches at its opposed ends for receiving peripheral portions of the lenses and their associated lens supports. The retaining notches define an abutment position in which the lenses are retained on their supports and a limit position permitting removal of the lenses through openings formed by the notches. The lens supports are resiliently mounted by the main bridge member to permit displacement outwardly and upwardly from the abutment position to the limit position.

Abstract: A spectacle frame wherein each lens is held against a rim by a thin wire for providing a rimless appearance is provided. The spectacle structure includes a wire having at least one enlarged end and a rim for receiving the lens with the enlarged end of the wire engaged in one end of the rim and secured at the opposing rim for compressively retaining the lens in the rim. The wire is formed of a super-elastic material, such as a Ni-Ti alloy.

Abstract: Safety glasses for use, in particular, in sporting activities comprise a frame to which two limbs are articulated, two lenses mounted on the inside of grooved retaining circles formed in the frame and a nose rest piece which fits together with the frame, is made of flexible material and has walls which form a part of the said grooved retaining circles. In such glasses therefore the lenses are partly held by flexible material which avoids their being broken in the case of a heavy blow as may for example occur when playing a sport. The risks therefore of cuts or injuries to the wearer of the glasses are reduced.

Abstract: The subject of the invention is represented by adjustable luminous intensity sun glasses of the type employing two pairs of polarizing lenses set before one another one pair of which is made up of two identical mobile synchronically rotating lenses which rotate on their axes in respect of the other pair whose lenses are fixed.The two fixed lenses are assembled onto an external frame component, equipped with stems and especially designed dap components relative to the internal side; the set may be adopted as a normal pair of glasses with polarizing lenses. The two mobile lenses are assembled--with the possibility of synchronous rotation around their axes--onto an inside frame component which is equipped with dap seats.
