Abstract: A fence rail includes a detachable fastener cover that covers and conceals a fastener chamber. Through the use of a knuckle and a catch fastening system, moisture is prevented from entering the fastener chamber. The fastener chamber allows for securing pickets to the rail using a means for fastening as close to the top of the rail as possible thereby allowing for significant racking of the fence.

Abstract: A protective cover for natural fiber apparel to protect the apparel from moths, moth larvae, and other pests is disclosed. The protective cover encloses not only natural fiber apparel, but also a hanger from which the apparel is hung. A substantial portion of the protective cover is made from a fabric that prevents moths and other insects from penetrating the protective cover and depositing eggs or consuming the apparel therein. At the same time, this fabric allows air to travel therethrough. A window is incorporated into the body of the protective cover to allow users to view the one or more apparel items protected by the protective cover. The protective cover also includes a zipper along its outer edge to allow access to the apparel contained within.

Abstract: A method and apparatus for initiating and maintaining an abnormal glow volumetric sonoplasma discharge (VSPD). With certain parameters of the electrical discharge and of the intensity of elastic vibrations, it is possible to initiate VSPD within a cavitating liquid medium. The mechanism for the initiation of VSPD is related to the breakdown of gas phase microchannels formed by growth cavitation bubbles. The method for continuous processing uses elastic vibrations in the frequency range 1-100 kHz with enough intensity for the development of cavitation phenomena; these vibrations are introduced into the liquid phase working medium, and a source of direct, alternating, high frequency and ultrahigh frequency electric field in liquid provides the initiation and stable glow of VSPD. Resulting VSPD is characterized by volumetric glow in the frequency range of visible light and ultraviolet radiation in the entire cavitational-electric field and has a rising volt-ampere characteristic curve.

Abstract: A method and device to determine quantitatively the surface optical characteristics of an object of reference made up of a plurality of optically differentiable layers. The device includes lighting and image capture means, connected to analysing means which execute the method to obtain the parameters of the repair material components best fitting the optical characteristics of the dental environment of the subject under treatment. The result of the analysis through the method in the invention consists mainly in the identification of each one of the various materials which should constitute the different layers, as well as their respective thicknesses, and which are to lead to a dental repair with optimum optical characteristics. It is thus achieved that the repair be visually imperceptible, both under natural light and under ultraviolet light.
