Abstract: A system for generating soft X rays. This system includes valve apparatus (22) for repetitively providing bursts of a gas of brief duration and a magnetic pulse compression power supply for providing high current pulses. The system further includes a transmission line connected to the power supply (13, 19) for transmitting power pulses from the supply to discharge through bursts of gas. The power supply (13) includes a plurality of series saturable inductor magnetic switches (51, 52) and a plurality of shunt capacitors (C1, C2). Thus, upon synchronized provision of a burst of gas from the valve apparatus and a power pulse from the power supply, a high current discharge generates plasma and an intense magnetic field which radially compresses the plasma, resulting in a dense, high temperature plasma which is an intense source of soft X rays.

Abstract: A fluid handling system is described wherein a small fluid volume (16) is placed on a reversibly-deformable support (12), which can be deformed to form a cavity. As the fluid clings to the surface of the support, it is physically agitated and mixed as the support is deformed. The deformable support can be utilized to provide fluid containers of varying sizes, to accommodate different fluid volumes and as a transport mechanism to move fluid from one location to another.

Abstract: A collapsible multilayer bag (10) formed from a plurality of substantially impermeable plastics sheets (14, 15,16) joined together around their peripheries is located within an inextensible outer casing, e.g. a cylindrical cardboard casing (11) with end plates (12, 13). Liquid, such as beer, can be filled into a first interlayer space (27) of the bag (10) via first inlet/outlet means (17) against a counter pressure provided by a pressure medium, such as air or water, in second interlayer space (28) which is gradually bled off via second inlet/outlet means (18). The liquid is subsequently dispensed by controlled supply of pressure medium to the second interlayer space (28) so as to exert pressure on the liquid filled space (27).

Abstract: One or more printing elements (16) in tube form with a capillary nozzle (20) at one end are mounted in aligned and mutually parallel relationship with a cavity (12) in a support (10). The printing elements have piezoelectric sleeves (18) thereon and are embedded in a filling (26) of polymerised resin which fills the cavity. They are disposed in such a way that the nozzles project externally from the support while the other ends (22) communicate with a common ink reservoir (31). The upper wall of the reservoir at each tube is arched with the highest region aligned with the corresponding tube in such a way that any bubbles in the ink can be easily expelled by way of the nozzles. A capillary filter (50) separates the chamber of the reservoir from an ink feed conduit (37) to prevent impurities or air bubbles from passing therethrough. In another embodiment, the reservoir (31) is partitioned into a plurality of separate chambers to ensure that emptying of one tube (16) does not affect operation of the adjacent tubes.

Abstract: An instrument for measuring acceleration as a function of reciprocal mode splitting within a non-planar rising cavity. A glass block (10) includes an internal non-planar cavity (24, 26, 28, 30). The block includes orthogonal bending axes (12, 14). A proofmass (60) atop the block causes flexure about such axes upon imposition of acceleration force (A, B) along a preselected sensitive axis. The resulting deformation results in detectable changes in the cavity aspect ratio that provide a measure of acceleration.

Abstract: A position of an actuation unit of a robot and a speed of a motor for driving the actuation unit are detected. A speed reference is produced on the basis of a deviation between a movement value and a position detected. Further, a torque reference is produced on the basis of a deviation between the speed reference and a speed detected. The motor for driving the actuation unit is subjected to current control. The magnitude of the torque reference is limited by a limiter (l2). This limiter (l2) operates only when a command for allowing the robot to be subjected to emergency stop is received, and carries out limiting operation on the basis of a function (F) which rises from the time point when the command is received. The provision of such a limiter (l2) permits the robot to be smoothly stopped even when emergency stop is required.

Abstract: To reduce the dust concentration in a filter system for gas turbines, a deflection collar is provided. The air vortex effects an increase in the height of the dust inlet. The decrease in the dust concentration is about 2/3. The process for the compact system is documented in Figures 2 and 3, which show the vertical arrangement of the filter modules in a V-shape, the fresh air duct (11), the extraction duct (10), the cleaning nozzles (18,19) and the extraction slots (15,16,17). The flow model - inflow, jet cleaning (26), extraction air, path of the dust particles, for example (22) - is a characteristic of the process according to the invention. Each individual module has an identical flow pattern. Recirculation of the dust is impossible. The dust concentration lowered to 1/3 increases the service life of the filter by a factor of about 3. The V arrangement of the filter panels (12), the occupation of 4 sides of the rectangle or of the circumference of the cylinder as a maximum reduces the constructional volume of the filter system to about 2/3. The elements of the modules form a rotational and flexurally stiff structure with integrated sound-attenuating links. The expensive supporting steel structure is unnecessary. <IMAGE>
