Abstract: Embodiments of the present invention include an aircraft with at least one fuselage, a wing, a power plant coupled to the at least one fuselage, a shroud surrounding a propeller of the power plant, and at least two floats coupled to the wing. In some embodiments, each float may further comprise a step positioned forward of a line that is at least 5 degrees rearward of a vertical line passing through a most aft empty weight center of gravity. In some embodiments, each float comprises a forward portion that is positioned forward of the step, wherein a ski surface is coupled to the forward portion, and an aft portion that is located aft of the step, wherein the aft portion of each float is configured to be wetted at taxiing speed. A rudder may be coupled to the aft portion. Each float may also include a retractable wheel and landing gear, wherein the wheel is preferably positioned on the line that is at least 5 degrees rearward of a vertical line passing through a most aft empty weight center of gravity.

Abstract: General aviation class amphibious aircraft which include two fuselages, each having a hydrodynamic surface, the fuselages connected via a primary flight surface and a ducted power plant located aft and above the fuselages. The power plant location removes the fan/propeller arc from water and spray during water-borne taxiing, takeoff and landing. The combination of fuselages, lifting surface and ducting provides an aerodynamically efficient design with a lower center of gravity and protected powerplant for yielding improved performance including increased range and airspeed, together with favorable maneuverability, stability and control characteristics both aerodynamically and hydrodynamically.

Abstract: A protective mask adapted to be worn by persons engaging in physical games comprises a body consisting of a lens receiving portion, a nose portion, a chin portion, a brow portion, opposite cheek portions and opposite side temple portions; the lens receiving portion displays an opening which is covered by a removable flexible transparent lens having its opposite extremities configured with engagement portions that mount the lens to the body. A pair of anchor clamps are inserted at each opposite end of the lens to further secure the engagement of the lens to the mask body.

Abstract: A protective mask adapted to be worn by persons engaging in physical games comprises a body formed of rigid plastic material including a nose portion, a chin portion, a brow portion, opposite cheek portions and opposite side temple portions; an opening is provided between the brow portion and the nose portion and cheek portions to be covered by a flexible transparent lens. A throat guard is pivotally mounted to the opposite cheek portions and extends inwardly of the chin and cheek portions; the throat guard is pivotal between two vertical positions relative to the chin and cheek portions and includes a tongue that extends towards the inner face of the mask and is adapted to contact an inner lower edge area of the mask to define the lowermost vertical position; the throat guard further includes a lower outwardly projecting area to contact the lower edge of the mask to define the uppermost vertical position for the throat guard.

Abstract: Sport eyeglasses having removable lenses formed of a one piece plastic molded frame that includes a pair of lens receiving sections, a pair of opposite strap receiving temple sections and a central bridge section integral with the lens receiving sections are described herein. The bridge section is split to define an upper bridge part and a lower bridge part which are capable of being manually distanced from one another so as to define a gap and allowing lenses to be mounted in the lens receiving sections. A fastening element extends through both bridge parts to secure them together once the lenses are installed in the lens receiving sections.

Abstract: The eyewear for industrial use comprises a deformable arcuate lens with a pair of temple receiving entries at opposite ends thereof, a deformable brow frame shaped to fit the upper edge of the lens so as to be engageable therewith and a pair of temple pieces, each piece being hingedly connected to a respective opposite end of the brow frame. Assembly of the temple pieces and brow frame to the lens is easily effected by inserting the temple pieces in the entries of the lens and by snap engagement of a mid-section of the brow frame to the upper edge of the lens. The assembly is made of plastic material so that it may be resiliently deformed to adapt to the various sizes of head of users.

Abstract: A protective eyeglass assembly for use during sport activities comprises a pair of separate lens frames individually cooperating with a lens holder to secure a pair of lenses therebetween. A detachable nose bridge interconnects the pair of separate lens frames with the lens holder so as to form a unitary eyeglass assembly, easily dismountable for lens replacement due to lens damage or lens prescription.

Abstract: An eyeglass construction is described and comprises a lens, a pair of lens engaging members, a pair of hinge members, and a pair of temple pieces. The hinge members are adapted to slidably engage the lens engaging members and to be connected therewith for pivotal movement about a horizontal axis. The pair of temple pieces each have a portion adapted to engage a hinge member and to be connected therewith for pivotal movement about a substantially vertical axis. The lens engaging member and the hinge member have cooperating angular positioning elements so that the members may be adjusted relative to one another to enable the lens to adopt various angular position relative to the temple pieces.

Abstract: The disclosure herein describes a lighting device which is adapted for use with a wheel bicycle and which includes a magnet mounted to one of the wheels and a housing mounted to the bicycle frame. A solenoid inside the housing has a winding and a core closely mounted to the wheel. A lamp is electrically connected to the solenoid winding so that light is emitted as a result of the magnet passing by the solenoid core as the bicycle wheel rotates. The electrical system includes storage elements which accumulate an excess of electrical energy during wheel rotation to thereby allow light to be emitted after the bicycle has come to a stationary position and until the excess has been used up.
