TL;DR: The periodic magnet structure for a periodically focused beam tube is formed by a single pair of homogeneous slabs of magnetizable material that are permanently magnetized with a pattern of magnetic poles of alternating polarity taken along the direction of the beam path.
Abstract: The periodic magnet structure for a periodically focused beam tube is formed by a single pair of homogeneous slabs of magnetizable material that are permanently magnetized with a pattern of magnetic poles of alternating polarity taken along the direction of the beam path. In a sheet beam tube of preferred geometry, a pair of ceramic slabs are disposed to straddle the sheet beam and the internal planar faces of the ceramic slabs have circuits printed thereon for: electrical connections to all elements, beam forming electrodes, microwave interaction structure, edge focusing electrodes, and the beam collector electrode structure. The permanently magnetized slabs are disposed external to the vacuum envelope, straddling the printed circuit ceramic slabs, for focusing the beam.

TL;DR: Quantitation of observable phosphate-containing metabolites in whole tissue and in perchlorate extracts demonstrated that 60% of the total ADP and 50% ofthe total Pi are 'NMR-invisible' in the intact fluke and therefore probably bound to macromolecules in the cells.

TL;DR: In this paper, an electrographic recording web is passed between the styli and the backup electrode, such film being supported on a conductive paper backing which makes electrical contact with the backup electrodes.
Abstract: The printer includes an array of electrographic styli electrodes disposed overlaying a backup electrode. An electrographic recording web is passed between the styli and the backup electrode. The recording web comprises a dielectric charge retention film facing the styli, such film being supported on a conductive paper backing which makes electrical contact with the backup electrode. A pulsed first writing potential is produced across the styli and the backup electrode, such first pulsed potential having a pulse amplitude and duration which is less than that which is sufficient to deposit a charge image on the recording medium but which has an amplitude and/or duration which varies in variable accordance with the density of the incremental charge image to be printed by a selective one of the styli on the recording web. A second pulsed potential is applied across the selected one of the styli and the backup electrode, such second pulsed potential being of generally invariant amplitude and/or duration and which, by itself, is insufficient to produce a charge image on the recording medium but which when combined with the first potential produces a total pulsed voltage of an amplitude and/or duration sufficient to deposit an incremental charge image on the recording medium, such deposited charge image having an average charge density in accordance with the density of the image to be printed to produce a gray scale printing capability.

TL;DR: In this paper, a vacuum connector is disclosed for connecting secondary replaceable evacuated devices to a primary evacuated system without contamination of the primary system, and an O-ring seal is provided for sealing the secondary evacuate structure to the wall of the gas passageway.
Abstract: A vacuum connector is disclosed for connecting secondary replaceable evacuated devices to a primary evacuated system without contamination of the primary system. A gas passageway is connected to the primary evacuated system. A valve spring loaded to the normally closed position, is provided in the gas passageway closing same. The secondary evacuated structure, to be connected to the primary evacuated system, is sealed by means of a diaphragm. An O-ring seal is provided for sealing the secondary replaceable evacuated structure to the wall of the gas passageway. A cutting tool is provided in the gas passageway between the valve and the diaphragm for cutting the diaphragm, thereby opening same. The cutting tool also engages the valve for opening the valve against the spring bias to place the secondary evacuated structure into gas communication with the primary evacuated system through the valve. Removal of the secondary evacuated structure causes the spring bias force to close the valve, thereby sealing the primary evacuated system for subsequent connection to a second replaceable secondary evacuated device.
