Abstract: The invention provides Bean pod mottle virus (BPMV) vectors useful for expression of heterologous proteins in plants such as soybean. The BPMV vectors are also useful for virus-induced gene silencing. The vectors of the invention include modifications of BPMV RNA1 sequences so that infection with the vectors produces only moderate symptoms. The vectors also comprise novel RNA2 vectors which specifically provide for non-translated VIGS constructs and further which do not require in frame insertion of heterologous sequences to be expressed.

Abstract: A brake assembly, having a plurality of co-operating rotating and non-rotating brake discs, includes a dump valve mechanism, including a spool valve. The spool valve is adapted to move between first and second positions to close and open fluid communications between a fluid supply passage and a fluid dump passage. Excess cooling fluid supplied to a brake assembly when the brakes are inactive causes "brake drag" which wastes power and decreases machine efficiency. By dumping the cooling fluid to a fluid dump passage when the brakes are inactive, the "brake drag" is reduced.

Abstract: A package for wax-like cosmetic stick product having a twist-up in the bottom of the package, the twist-up comprising a base, spindle and elevator, vents in both said base and elevator, and a cap affixed to the package, wherein said package is filled through the bottom through an opening in the elevator.

Abstract: Microwave moisture measuring apparatus in which a plurality of transmitting antennas direct microwave radiation through individual portions of a moisture-containing sheet material to respective receiving antennas coupled to a common detector. A microwave pulse is provided to one end of a transmission line containing delay elements to provide successively delayed pulses to the transmitting antennas. The delayed pulses are separately received by the detector and analyzed to permit individual measurement of the moisture content of the sheet material portions.

Abstract: A centrifuge for separating a solids-liquid slurry includes a rotor, rotatable about a vertical axis, with a vertically upstanding central drive shaft, frusto-conical discs vertically spaced one from another about the shaft, a hollow housing connected to the shaft and rotatable unitarily therewith, surrounding the discs and spaced therefrom, with the housing having a frusto-cylindrical central portion with horizontal nozzles for discharge of thickened solids therethrough and having upper and lower frusto-conical skirt portions which taper from the central portion towards the shaft. A stationary casing surrounds the rotor. Space between the casing and the central drive shaft defines a liquid outlet; a thickened solids outlet extends from the lower portion of the casing. A stationary inlet feed tube extends into the housing through a lower portion of the casing.
