Abstract: A composite material includes a first metallic material component and a second metallic material component. The first material component is different from the second material component. The second material component is mixed with the first material component.

Abstract: The invention relates to a camera chip (C) for image acquisition. It is characterized in that pixel groups (P1, P2, . . . ) may be exposed at different times with the aid of shutter signals (S1, S2, . . . ).

Abstract: An electrically weldable spring hinge for eyeglasses includes a housing open on a bottom side having a cavity into which a spring element may be inserted and in which at least one support element is provided. The spring hinge additionally includes a hinge element displaceably supported in the housing. The at least one support element is essentially centrally located in the region of an open end face section of the housing and, starting from a base area of the housing, protrudes into the cavity in a freestanding manner. A welding button for electrically welding the housing to the eyeglass element is provided on the bottom side of the support element facing an eyeglass element.

Abstract: The invention relates to an electrically weldable spring hinge (1) for eyeglasses, comprising a housing (3) which is open on a bottom side (15) and has a cavity (17) into which a spring element (7) may be inserted and in which at least one support element (19) is provided, and a hinge element (5) which is displaceably supported in the housing (3). According to the invention, the at least one support element (19) is essentially centrally located in the region of an open end face section (S) of the housing (3) and, starting from a base area (B) of the housing (3), protrudes into the cavity (17) in a freestanding manner, and a welding button (23) for electrically welding the housing (3) to the eyeglass element is provided on the bottom side (21) of the support element (19) facing an eyeglass element.

Abstract: A spring hinge for spectacles having a center piece and side pieces fitted pivotably thereto is proposed, having a spring element cooperating with said side pieces, a housing having a recess receiving the hinge element and the spring element, within which housing the hinge element is displaceably disposed, and having a locking body disposed in the recess, the locking body having a receiving region and the housing having a deformation region which is displaceable into the receiving region. The spring hinge is characterized in that the receiving region is configured such that the locking body, and hence the hinge element, is prevented from being twisted and from being pulled out of the recess.

Abstract: A screw connection for hinge parts, especially of an eyeglass frame, comprising a screw that interconnects the hinge parts that engage one inside the other and that have an upper hinge lobe, a lower hinge lobe, and at least one middle hinge lobe, the screw having a screw head and a screw shank that extends through a first through opening in the upper hinge lobe and extends through a second through opening in the middle hinge lobe, with a thread permitting the screw shank to be screwed into the lower hinge lobe, and comprising a sleeve that surrounds the screw shank, has elastic properties, and interacts with the upper and middle hinge lobes when the screw is in a screwed-in state, whereby the diameter (D2) of the second through opening is less than or equal to the diameter (D1) of the first through opening.

Abstract: The invention relates to a spring hinge for spectacles, having a housing (3), a hinge part (5), which is arranged such that it can be displaced at least partially within the housing (3), a closure part (7), which is arranged in the housing (3), a spring (9), which is supported on the hinge part (5), on the one hand, and on the closure part (7), on the other hand, and having a stop device which has two stop elements. The invention is distinguished in that one stop element (33) is arranged on the hinge part (5), and the other stop element (63, 67) is arranged on the housing (3) or on the closure part (7), such that the capacity of the hinge part (5) for displacement counter to the spring force of the spring (9) is limited to a predetermined distance (w).
