Air spring strut for a motor vehicle including an air spring with a shock absorber for spring-cushioning and damping oscillations of a motor vehicle running gear assembly. The air spring includes an air spring cover and an air spring piston. An air spring bellows made of elastomeric material is clamped air-tightly between the air spring cover and the air spring piston partially delimits a working space filled with compressed air and, while forming a rolling fold, rolls on the air spring cover and / or the air spring piston. The air spring cover is embodied in two parts with a first cover part for receiving an absorber bearing and with a second cover part for fastening the air spring bellows. The first cover part is manufactured from metal and the second cover part is manufactured from plastic.

Parabolic reflector includes a number of sectors (2) being connected to each other at a central hub (3), the parabolic reflector being collapsible from an extended position (9), in which the sectors together extend 360 °around the hub (3), to a retracted position (8), in which the sectors (2) are brought together into a compact unit. Each sector (2) is rigid and is firmly joined to a cylindrical hub sleeve (4). The hub sleeves (4) together form the hub (3), around which the sectors (2) are journalled for limited movement around a central axis extending through the center of the hub (3). The hub sleeves (4) are concentrically arranged one radially inside the other with consecutively decreasing radii, and the hub sleeves (4) have mutually cooperating guiding surfaces that permit axial displacement of the hub so as to enable relative rotation there between.

Power-saving techniques are employed in sensing a group of non-volatile memory cells in parallel. One technique is that the coupling of the memory cells to their bit lines is delayed during a precharge operation in order to reduce the cells' currents working against the precharge. Another technique is that a power-consuming precharge period is minimized by preemptively starting the sensing in a multi-pass sensing operation. High current cells not detected as a result of the premature sensing will still be able to be detected in a subsequent pass.

A piston for an axial machine includes a piston body having a cavity that is closed in a pressure-tight way. The cavity is divided into a plurality of chambers, arranged one beside the other in cross-section.

The assembly may also include an engagement mechanism positioned at the delivery tube attachment end. The assembly may also include a containment seal coupled to the delivery tube second end. The assembly may also include an inner containment seal positioned within the delivery tube cavity to seal the dosage form within the delivery tube cavity.

Electromagnetic energy is applied to thereby oscillate a bubble that is then insonified to produce an echo (260) for reception and analysis to afford imaging of the region of the bubble. To create the bubble, the energy may be applied to a nano particle (232) of a contrast agent whose consequent internal nano- or micro-bubbles offer, with novel pulsing techniques, greater sensitivity, and which can permeate outside vasculature (216) prior to being energized thereby affording quantification of vascular permeability and delivery of targeting molecules. The particle can include an absorbing and an evaporating parts, the irradiation (204), as by near-infrared laser, causing the phase change that gives rise to the bubble. The echo may occur in response to ultrasound interrogation (220) of the activated contrast agent, which could entail pulse inversion, power modulation or contrast pulse sequence imaging, with persistence processing. The contrast agent might be mixed with microbubble based ultrasound contrast agent to facilitate the timing of bubble activation.

Irradiation targets, useful in preparing radioisotopes by exposure of the target to a neutron flux in instrumentation tubes of a nuclear power reactor, are prepared by a method comprising the steps of:providing a powder of an oxide of a rare earth metal having a purity of greater than 99%;consolidating the powder in a mold to form a round green body having a green density of at least 50 percent of the theoretical density; andsintering the spherical green body in solid phase at a temperature of at least 70 percent of a solidus temperature of the rare earth metal oxide powder to form a round sintered rare earth metal oxide target having a sintered density of at least 80 percent of the theoretical density.
