Abstract: This is a method of filtration of a liquid comprising steps of sequential filtration of said liquid through at least one deep bed medium producing at least one first filtrate followed by at least one membrane medium filtration producing at least one second filtrate, wherein said membrane medium is at least periodically within said deep bed media Many types of deep bed and membrane media can be used. The domain of using contact clarification (direct filtration) can be expanded towards greater solids concentration. Operation and backwash, is simplified, continuous filtration becomes possible. Water can be water from natural source water, process water, wastewater, aqueous or non-aqueous suspensions, emulsions, solutions. Treatment can include mechanical interception of suspended particles, chemical, physical chemical, electrochemical, and biological processes.

Abstract: An inflatable snowshoe. In its deflated state, it can be flattened and rolled, which allows a pair of these snowshoes to be stored inside the cowling of a snowmobile. The snowshoe consists of a web flotation deck that has a tubular shaped air bladder frame. When inflated, the frame and deck take on the properties of a rigid conventional snowshoe. A puncture and abrasion resistant fabric covers the inner membrane that forms the bladder type, tubular air chamber. This air chamber makes up the peripheral frame of the snowshoe and is held to its teardrop shape by the multi-point restraint of the nylon web flotation deck. The nylon web flotation deck distributes the weight of the wearer. The binding attachment and the cross points of the nylon straps that form the deck are affixed with metal rivets, which also act as traction studs.

Abstract: A fishing board game that is designed to be carried in a fishing tackle box style container. The lower portion of the box holds the board, score pads, instructions and bag limits. The upper portion of the box has a tray similar to those found in regular tackle boxes. The tray has six compartments to hold the playing cards, game tokens and die. The game board covers a wide portion of south-central Alaska. This area provides a wide variety of fishing choices and opportunities. Players move around the board, using a die to count spaces. Spaces include fish-on spaces, fly-in fishing spaces, float trip spaces and chance spaces. Players move around the board, catching fish and attempting to avoid trouble. There are several options for scoring and for the type of fishing that can be performed. At the end of the game, the player with the most points wins.
