Abstract: The invention relates to a method for the detection of oligonucleotides using anion exchange high performance liquid chromatography. Fluorescently labelled peptide nucleic acid oligomers, complementary to the oligonucleotide are hybridized to the oligonucleotides. Anion exchange high performance liquid chromatography is then performed and the hybridized moieties detected and quantitated. The invention also relates to a method for the simultaneous detection of both strands of an oligonucleotide in parallel from one sample, and a kit for use in qualitative and quantitative detection of one or two strands of an oligonucleotide.

Abstract: A method for charging pallet cars of a traveling grate for the thermal treatment of bulk material includes in a first step a first layer is applied as a hearth layer on a grate surface of the pallet car. In at least one second step a second layer at the same time or successively is applied as a side layer on two opposed side walls of the pallet car and a third layer is applied as green pellet layer between the side layers and on the hearth layer. The pellets used for the grate and the side layer differ in terms of their diameter and size distribution.

Abstract: A machining apparatus for a shaft-type workpiece has a housing or frame defining a pair of spaced and upright side walls and a vertical front wall bridging the side walls. Vertical guides on one of the side walls carry a vertically shiftable headstock and tailstock capable of rotating a workpiece about an upright axis. Horizontal guides on the front wall carry a turret adapted to hold first machining tools and horizontally shiftable for engagement of the first tools with a workpiece held and rotated by the headstock and tailstock. A holder on the other of the side walls can hold a workpiece with an end of the workpiece exposed so that a second tool can engage and machine the exposed end of the workpiece.

Abstract: A machining apparatus has a frame defining a transfer station and a machining station thereabove, a spindle having a workpiece grab and vertically displaceable on the frame between an upper position with the grab in the machining station and a lower position with the grab in the transfer station, a tool holder horizontally displaceable on the frame toward and away from the machining station, and a workpiece conveyor extending through the transfer station. After shifting a deflector underneath the machining station into a side position out from underneath the grab, the grab is lowered to pick an at least partially unmachined workpiece in the transfer station off the conveyor and then raised with the workpiece into the machining station. The deflector is then shifted between a use position over the transfer station and under the machining station and a side position allowing the spindle to pass.
