摘要:
An optical filter composite is provided having effective filtering of infrared emissions, such as solar or laser emissions, while providing very high visible light transmission, preserving the ability to differentiate and recognize colors and providing a pleasing overall color as compared to the prior art. The present invention provides for filters that are formed by lamination, infusion and/or coating processes using filtering assemblies having a neutral color with high visible light transmission while also producing high levels of filtration in the infrared and near infrared range to provide effective protection against harmful emissions in these ranges while also producing a filter that has a color that is more pleasing and desirable to the wearer.

Ophthalmic lenses, coatings for ophthalmic lenses, and methods for manufacturing ophthalmic lenses are provided herein. In one exemplary embodiment, an ophthalmic lens comprising a polymeric lens has a first surface and second surface. A coating overlies the first surface. The coating comprises a polysiloxane, a polyurethane, an oligomer derived from a polysiloxane or a polyurethane, a polymer derived from a polysiloxane or a polyurethane, or a combination thereof, and a fluorinated material. The coating exhibits a water contact angle of greater than 90° as measured by a goniometer.

摘要:
An improved coating system for an ophthalmic lens that provides improved characteristics in the form of abrasion resistance, while also providing improved manufacturability and rapid curing as compared to prior art coating systems. The coating system is a composite coating that hybridizes both epoxy and acrylate coating materials into a single coating system. The coating material of the present disclosure includes at least a poly (meth) acrylate polymer, a polymerizable monomer containing at least one epoxy group and a cationic polymerization initiator. The coating may be further enhanced by the addition of colloidal nano-silica particles that serve to reinforce the mechanical properties of the coating system without compromising the overall transparency and optical clarity of the coating.
摘要:
Acoustically insulated machines have an internal source of noise and an insulation member. The insulation member may include a plurality of porous, sound absorbing layers and a plurality of dense or facing layers attached to faces of the sound absorbing layers. The dense or facing layers each have a density that is greater than the densities of the sound absorbing layers. The insulation member may be oriented such that one of the dense or facing layers faces toward the internal source of noise. The insulation member may be configured such that most of the low frequency sound energy generated by the internal source of noise is not reflected back into the machine. That is, the dense or facing layer may be configured to allow a majority of low frequency sound energy from the internal source of noise to pass into the insulation member.

Embodiments of sawhorse systems are shown and described, which may include one or more sawhorse-stand units. A sawhorse stand unit may comprise one or more top bracket, and one or more bottom bracket, which are coupled to vertical supports. Additionally, a horizontal member may extend between top brackets of the sawhorse-stand units. The horizontal and vertical supports may correspond, in size and shape, to dimensional lumber.
摘要:
An insulation element is provided for installation in a gap of thickness G provided between two objects. The insulation element includes a body made from a thermoplastic polymer material. The body has a first face, a second face and a thickness defined between the first and second faces. The body is characterized by a semi permanently pre-installation thickness T1 where T1 is less than G. The body swells upon heating to a thickness T2 where T2 is greater than or equal to G so that the insulation element bridges the gap, engages the two objects and provides a spring rate of between 4.0 and 275.0 grams per square inch.

摘要:
A dishwasher tub includes a main body having opposing side walls that are interconnected by a rear wall, all formed from a multi-layered composite material. A cap member is joined atop the opposing side and rear walls, a base member is joined to lower edge portions of the opposing side walls and rear wall, and a frontal halo member is mounted between the cap and base member to define an overall washing chamber having a front opening. Preferably, the multi-layered composite material includes an inner stainless layer, a rigid layer and an outer protective layer, such as a layer of stainless steel, a rigid polyester mat, and a protective layer of hard plastic or aluminum foil. The outer layer also preferably serves as a shipping container for the dishwasher, enabling components of the dishwasher to be transported to a designated location for final assembly.
