Abstract: The present invention relates to a method of producing germanosilicate. The formed germanosilicate comprises a refractive index change ?n. The method includes forming a gel from a sol comprising germaniumoxide, or a precursor thereof, and silicate, or a precursor thereof, by means of a sol-gel process. The method further includes forming germanosilicate by annealing the gel under elevated temperature and exposing the formed germanosilicate to pulsed UV light of at least 350 mJ/pulse.

Abstract: A spectacles includes two lenses, a spectacles frame and an adjustment hinge arrangement. The spectacles frame includes two supporting arms and a bridge extending between the two supporting arms. The adjustment hinge arrangement pivotally couples the two lenses with the two supporting arms respectively to pivotally fold the two lenses between an idle position and an usage position, wherein at the idle position, the two lenses are upwardly and pivotally flipped to move away from the bridge, and at the usage position, the two lenses are downwardly and pivotally flipped at a position that the bridge is positioned between the two lenses.

Abstract: A spectacles set includes a primary spectacles and a magnetic auxiliary frame. The magnetic auxiliary frame includes two auxiliary lenses, an auxiliary frame body, and a magnetic mounting arrangement including at least one magnetic holder and at least one supporting arm. The magnetic holders are spacedly mounted at the auxiliary frame, wherein each of the magnetic holders includes a frame holder detachably mounted to the primary spectacles frame of the primary spectacles, and a magnetic seat supported by the frame holder. The supporting arms are rearwardly or frontwardly and spacedly extended from the magnetic auxiliary frame to substantially align with the magnetic seats respectively, wherein each of the supporting arms comprises a magnetic member magnetically attract with the respective magnetic seat to detachably mount the magnetic auxiliary frame in front or back of the primary spectacles frame.

Abstract: A culinary spatula comprising a main body including a handle portion and a utility portion having a front end covered with an elongate member made of a heat resistant soft plastic material, and across the front end wherein the member sandwiches and/or is fixedly attached to the front end such that the member and the front end together integrally form the utility portion of the spatula.
