Abstract: A round bale wrapping mechanism that employs a pivoting carrier for two wrapping material rolls, one a stored roll and the other the working roll being dispensed. When the storage roll is to be employed, it is pivoted into contact with the material being dispensed from the working roll and pulled through the threading components of the wrapper. The storage roll thus becomes the working roll and a new storage roll may be installed in place of the empty storage roll (previously the working roll).

Abstract: A method of measuring the quantity of wrap remaining on a round baler supply roll uses the existing wrap measuring apparatus of a round baler. An on-board microprocessor is programmed to calculate the minimum amount of wrap required for each bale, subtract the amount of wrap used to wrap a bale from the amount of wrap on the supply roll before wrapping the bale, and signal the operator if the amount on the roll is insufficient to wrap a bale. The microprocessor can also be programmed to signal the operator if the amount of wrap on the roll is insufficient to wrap a number of bales specified by the operator.

Abstract: The invention describes the synthesis of a panel of novel carbon-carbon linked carboranyl-containing 5,10,15,20-tetraphenylporphyrins bearing 25–44% boron by weight. In certain embodiments, a phenyl porphyrin compound has a carboranyl group attached to the phenyl group by a carbon-carbon linkage, wherein the phenyl group corresponds to the following formula where R7 through R11 are hydrogen, a carboranyl group, or are selected from the group consisting of hydroxyl, NMe3+, PMePh2+, PO(OH)2, SO3H, COOH, and NH2. In this embodiment, the carboranyl group is attached to the phenyl group by a carbon-carbon linkage, either one or two of R7 through R11 are other than hydrogen; and the phenyl porphyrin compound contains at least one phenyl group having at least one of said carboranyl groups.

Abstract: A single floating windguard that pivots at the front and the middle of the tine section causing the tines to maintain contact with the crop at all times as it moves over the pickup and across the stuffer assembly.

Abstract: A pickup for an agricultural implement, the pickup including dual floating windguards that pivot and float causing the tines to maintain contact with the crop at all times as it moves over the pickup and across the stuffer.

Abstract: Brackets received in an elongated base support both lens portions and internal light bar components. Lens portion longitudinal edges penetrate the outer portion of a gasket channel to engage a gasket member. Lens retainer straps sandwich gasket layers to seal the longitudinal butt ends of lens portions. The lens retainers also penetrate the gasket channel to engage the gasket member. The brackets provide multiple locations for mounting warning light units and related light bar components within the space defined between the base and the lens portions.

Abstract: A modular rotatable warning light incorporates a standardized shaft, rotatable sub-assembly, motor and worm gear to form the mechanical core of the assembly. The rotatable sub-assembly includes a rotatable reflector mount supported by two axially spaced bearings for rotation around a hub. The axially spaced bearings significantly improve the function and service life of the rotatable warning light. The standardized parts are combined with a selected base plate, lamp holder, lamp and reflector to produce a modular rotatable warning light having a specified overall configuration. The efficiency of production and maintenance of various rotatable warning light configurations is improved by reducing engineering, production, maintenance and inventory costs.

Abstract: The present invention relates to a nickel-porphyrin derivative in a matrix, the nickel-porphyrin derivative comprising at least two conformational isomers, a lower-energy-state conformer and a higher-energy-state conformer, such that when the higher-energy-state conformer is generated from the lower-energy-state conformer following absorption of a photon of suitable energy, the time to return to the lower-energy-state conformer is greater than 40 nanoseconds at approximately room temperature. The nickel-porphyrin derivative is useful in optical memory applications.

Abstract: The present invention provides a bale slicer that processes large forage bales into a form useable by TMR mixing systems. The bale slicer is simple to operate, reduces the power required to process a bale as compared to other bale processors and processes forage bales into a size suitable for use as feed. The bale slicer includes a main frame, bale chamber, platforms, a cutting mechanism, and power mechanism. The bale slicer utilizes a slicing motion by the cutting mechanism to process the large forage bales. The forage bale to be processed remains stationary and is held in its compressed form by the bale chamber during slicing. The cutting mechanism passes by the bale chamber in order to slice the bale. At the end of each slice made by the cutting mechanism, the forage falls to the floor and the bale drops down in the bale chamber in preparation for the return pass by the cutting mechanism. The fallen forage is then ready to be transported to a TMR mixer.
