  • Patent number: 8958151
    Abstract: Provided are an ocular zoom optical system which has a wide apparent field of view even on a low power side and in which aberrations are favorably corrected while a sufficient eye relief is secured over the entire zoom range, and an optical instrument including the ocular zoom optical system. The ocular zoom optical system 3 includes, in order from the object side: a first lens group G1 having a negative refractive power; a second lens group G2 having a positive refractive power; and a third lens group G3 having a positive refractive power and at least one aspheric surface. An intermediate image I? is formed between the first lens group G1 and the second lens group G2. During zooming, the third lens group G3 is fixed on the optical axis, and the first lens group G1 and the second lens group G2 are moved in directions opposite to each other with the intermediate image I? interposed therebetween.

  • Patent number: 8657517
    Abstract: A container and applicator assembly that is used to hold and apply a liquid. The container has a threaded neck, through which the interior of the container is accessible. A removable cap is provided that selectively engages the threaded neck to create a leak-proof seal. An applicator brush extends downwardly from the center of the cap. The applicator brush extends into the interior of the container when the cap is engaged with the threaded neck. A support arm also extends from the cap. The support arm remains external to the container even when the cap is set. A magnifying lens is coupled to the end of the support arm. When the cap is separated from the container, the magnifying lens magnifies the bristle tip of the applicator brush. When the cap is set in place on the container, the magnifying lens magnifies a portion of the label.

  • Patent number: 5119677
    Abstract: A gauge protector provides a shield device for the protection of the lenses of skin diving gauges and related articles, and includes one or more crossbar elements extending between crossbar base portions, of a size and shape to fit over the gauge lens, and attaches to the outside of the dive gauge body and/or its associated flexible protective boot member. The crossbar base portions preferably include downwardly-extending peripheral flange portions for releasable capture of the sides of the gauge body and/or protective boot member, and may themselves include open portions to enable passage of a gauge hose, strap, or similar member. Alternatively, any other method of attachment to the gauge body or boot member may be used, including friction-fit, toothed grasping, strapping, mechanical connection, or the like.
