Abstract: A method and apparatus for transforming color signals. The transformation is achieved by use of a first, coarse, look-up table and a second look-up table that provides coefficients to be used in calculating a correction vector. The vector of color components from the first look-up table is added to the correction vector to provide the transformed vector. The method and apparatus have particular application in the display of digital video signals.

Abstract: A device is provided for forming a knot in a fishing line or the like in order to attach a fish hook or other item of fishing tackle thereto or to join the line to another line. The device 131 has support means 132 with three fingers or other suitable nodes 133, 134 and 135 extending therefrom in spaced relationship. The middle or second finger or node 134 is offset from a line joining the first and third fingers or nodes 133,135, each finger or node having means associated therewith which cooperate to allow the tying of a hangman's knot or uni-knot. The first finger or node 133 has means 139 to retain and rotate the free end of the line after it has passed around the other two fingers or nodes so as to be able to twist the free end 164 of the line about both a first primary portion 137 of the line and a second return portion of the line 163 to form the knot.

Abstract: A combustion system for burning firewood including a combustion chamber defined by front, rear and side walls, a ceiling and a bottom. An access door is provided for addition of fuel into the combustion chamber. A substantial amount of combustion air enters the combustion chamber near the top of the fueling doors via apertures and is directed down the face of the fueling doors providing cooling. A geometry of the air metering orifice is either fixed or of limited adjustability such that the minimum flow of combustion air required for flaming combustion of a full load of fuel is maintained at all times. The combustion air flow cannot be reduced beyond a certain point and thus smoldering and very low air/fuel ratios are avoided.
