Abstract: A mobile frame (10) for supporting an elongate flexible structure (11) such as a ground working tool assembly, the mobile frame (10) is foldable between a first position in which the elongate flexible structure (11) is supported in a working condition in relation to the ground, and a second position in which the elongate flexible structure (11) is supported in a stored condition in relation to the ground. The mobile frame comprises a first frame portion (31) supported for movement over the ground and a second frame portion (32) for supporting one end of the elongate flexible structure. The second frame portion is mounted on the first frame portion for folding movement with respect thereto about a pivot axis inclined to the fore-and-aft axis of the mobile frame such that the spacing between the ends of the elongate flexible structure (11) increases as the elongate flexible structure is moved from the first position to the second position.

Abstract: A method of fabricating a metal-ferroelectric-metal ("MFM") capacitor includes the steps of depositing a silicon dioxide layer on a silicon or other substrate, a lower platinum or other noble metal electrode, a PZT or other ferroelectric material dielectric layer, and an upper platinum or other noble metal electrode. The upper electrode and ferroelectric dielectric layer are patterned and etched according to a first pattern corresponding to the final dimensions of the ferroelectric dielectric layer. The upper electrode and lower electrode are subsequently patterned and etched according to a second pattern corresponding to the final dimensions of one or more upper electrodes and the final extent of the lower electrode. The second etching step leaves a benign vestigial upper electrode feature. An oxide layer is finally deposited over the entire surface of the MFM capacitor structure, which is etched and metalized over desired upper and lower electrode contacts.

Abstract: A substantially neutral metal alkanoate solution suitable for application of the constituent micronutrient metal to agricultural crops or acreage where such crops are to be grown, is disclosed. Alkanoates having from 2 to 6 carbon atoms are preferred, with acetates most preferred. Metals selected from the group consisting of boron, calcium, copper, iron, magnesium, manganese, molybdenum, potassium, sodium and zinc are preferred, with zinc particularly preferred. The compositions of the present invention remain soluble at and below freezing temperatures for extending periods, and exhibits a high degree of miscibility in fertilizers. A method of manufacturing the compositions of the present invention is disclosed, in which a metal oxide is dispersed in water, ammonia is added to the dispersion, and acid is added to the basic dispersion to solubilize and substantially neutralize the dispersion and create an aqueous micronutrient solution.

Abstract: An apparatus and a method are provided to monitor a generally transparent blood tube at a location that is downstream from a blood separator in order to detect the presence of red blood cells in a tube that is intended to carry a different blood component, for example platelets. A red light source and a green light source are located in relation to the tube so that red light emission and green light emission are directed toward the tube and toward the flowing blood component(s) that is carried within the tube. The red light source produces a red reflection intensity from red blood cells whose magnitude increases as a function of an increase in the concentration of red blood cells. The green light source produces a green reflection intensity from the red blood cells whose magnitude decreases as a function of an increase in the concentration of the red blood cells.
