Abstract:
A method of bonding materials may comprise defining a bond interface between two materials in a cure zone on a surface of an object, and non-conductively heating the bond interface without directly heating the surface outside of the cure zone. Non-conductively heating the bond interface may involve applying microwave radiation to the bond interface.
Abstract:
The presently disclosed subject matter relates to a flotation device suited to teach beginner swimming techniques or provide enjoyment in an aquatic environment while providing flotation to at least a portion of the swimmer's body. The flotation device for aiding a swimmer in a body of water may comprise a body formed from an extruded foam and comprising a top surface, a bottom surface, a first side rail, a second side rail, a leading lateral surface, and a trailing lateral surface, and wherein the extruded foam is a flexible cellular foam. The presently disclosed subject matter also relates to methods of making the flotation device.
Abstract:
A diving suit made of a rubber material comprising HNBR (hydrogenated nitrile butadiene rubber) is disclosed, as well as a process for the production of the diving suit and the use of HNBR in a rubber material of a diving suit for use in contaminated water.
Abstract:
Disclosed are a pair of multicolor frameless diving masks and a method for making the same. The method mainly includes injection molding a skirt of a cover body of the diving masks in a first mold; applying an adhesive to an edge of the skirt and an edge of a lens; and placing the skirt and the lens in a second mold and injection molding the remaining portion of the cover body. Thus, the cover body of the diving masks is integrally formed in the second mold to produce a leakproof diving masks having different hues.
Abstract:
A sonic welded gas mask and the process for fabricating the mask. The facepiece of the mask provides apertures, appropriately shaped and dimensioned to receive gas mask components for sealing therein. The elastomeric material of the facepiece of the mask is captured between sealing elements and secured therebetween by a sonic welding process. The method of fabrication described attaches and positively seals the elements into the mask. Direct voice communication and alternatively, electronic voice communication may be provided between a user and the external environment.
Abstract:
A material for use in making at least part of an underwater diver's dry suit comprises at least two sections of a composite material abutted and secured together along a pair of adjacent edges, the material comprising an outer layer of waterproof material, an inner layer of material, and a middle layer of permanently collapsible cellular material, the abutted edges comprising a seam line formed by compressing the material of both sections to permanently collapse the cellular material of the middle layer.
Abstract:
A prefabricated concrete pool including concrete walls and a pan-formed concrete floor, as well as a method of fabricating a prefabricated swimming pool, the method including erecting an external wall form, erecting an internal wall form opposing the external wall form, and positioning pan forms on a floor form.
