Abstract: A polyphosphonate, a lens including the polyphosphonate, a camera module including the polyphosphonate lens, and a method of producing the lens are provided. The polyphosphonate includes a constitutional repeating unit comprising a phosphate ester group and an aromatic ring, and the phosphate ester group is directly bonded to the aromatic ring in the constitutional repeating unit.

Abstract: The present invention relates to a bi-layer pre-oil valve assembly and method of making that may be attached to a receptacle that provides a fluid resistant seal but allows for the expulsion of air pressure from the interior of a receptacle. The valve assembly may include a base layer, an adhesive layer, a fluid layer, and a material layer. The fluid layer may be a low viscosity fluid that is applied during the manufacturing of the valve and incorporated into the layer of the valve. The base layer may include an aperture. The adhesive layer may be provided about a portion of the perimeter of the base layer to define a non-adhesive portion. The fluid layer is applied along a portion of the non-adhesive portion of the base layer to define a channel or path to facilitate the release of gas or fluid from the receptacle.

Abstract: A mower deck gauge wheel support includes a one-piece sheet metal bracket mounted to a mower deck, having a sleeve mounted thereto outside a skirt of the mower deck, a wheel shaft inserted through the sleeve, and a J-pin having a first end that engages the wheel shaft at a desired cutting height, and a second end that is engaged by and retained by a coil spring within the bracket.

Abstract: A mower deck spindle cover includes a panel that covers a spindle pocket on a mower deck in a lowered position. The spindle cover is attached to a mounting arm for pivoting between the lowered position and a raised position. A torsion spring biases the panel to the lowered position. The spindle cover cannot be removed from the mower deck unless the mower deck is separated from the tractor or vehicle.

Abstract: A material collection parking system having a hopper connected to a rear discharge chute from a mower deck on a lawn tractor. The system includes a pair of front and a pair of rear parking support legs, at least one of the pairs of legs being independently moveable between a stowed position along a side wall of the hopper and a deployed position supporting the hopper on a ground surface. The material collection system has a low dump configuration and a high dump configuration providing unobstructed sight lines and rear visibility for the operator during rear collection in the stowed position on the lawn tractor.
