Abstract: This active suspension system includes suspension actuators (4) for the vehicle wheels which can be controlled to produce variable supporting force, and means for detecting the amount and the rate of relative movement between at least one vehicle wheel (2) and the vehicle body (3). A calculation and control means inputs from the detecting means signals indicative of the amount and the rate of relative movement between the wheel and the body, and based thereupon determines the vertical displacement of the road surface portion upon which this wheel is running. When this vertical displacement is within the stroke limit of the actuator for this wheel, the actuator is controlled to produce a support force for the body over this wheel sufficient to support the appropriate load component of the body; while, when this vertical displacement exceeds the stroke limit of this actuator, the value is calculated corresponding to the support force for the actuator necessary to travel along the road surface portion, and based thereon the actuator is controlled to alter the support force for the body over this wheel.

Abstract: To produce ozone from air, the latter is treated in a pressure change adsorption plant (3) in a manner such that a starting gas containing 90 to 98% by weight of oxygen, the remainder essentially being nitrogen, is supplied to the downstream ozoniser (6). The gas mixture leaving the ozoniser (6) is supplied to the ozone consumer, for example a drinking water treatment station (7). The unconsumed gas mixture passes via a residual ozone destroyer (10) and an optional gas purification stage (11) back to the pressure change adsorption plant (3). In this manner, ozone can be produced economically using a comparatively small pressure charge adsorption plant. <IMAGE>

Abstract: A transportation system of a floated-carrier type according to this invention includes a carrier (2) capa­ble of running along guide rails (l) with a cargo and load carried thereon. A magnetic unit (l2-l to l2-4) is mounted on the carrier (2) to float the carrier (2) from the guide rails (l). A slowing-down device (4) is pro­vided to slow down the carrier (2) when the carrier (2) is just about to enter into a stop position. Projec­tions (35-l to 35-4) of ferromagnetic material are pro­vided on the side of predetermined portions of guide rails (l) which the magnetic unit (l2-l to l2-4) of the carrier (2) confronts when the carrier (2) is stopped in the stop position. The magnetic unit (l2-l to l2-4), together with the guide rails, establishes a magnetic circuit. The magnetic resistance in the magnetic cir­cuit is smaller at the predetermined portions of the guide rails where the aforementioned projections (35-l to 35-4) are provided than at other portions of the guide rails. When, in this case, the carrier (2) arri­ves substantially at the stop position, the magnetic flux due to the magnetic unit flows through the afore­mentioned magnetic circuit in an increasing amount, assuring an increased attractive force between the magnetic unit (l2-l to l2-4) and the predetermined por­tions of the guide rails (2) where the projections (35-l to 35-4) are provided. As a result, the carrier (2) is attracted toward the location of these predetermined portions of the guide rails (l) so that it is positioned precisely in the stop position.

Abstract: A method of deploying a cable or other line (34) in a fluid transportation pipeline (10) whilst in normal operation full of and transporting a fluid (12) under a positive pressure. A collapsible centralising device (62,64) is attached to the leading end of the cable (34) and is then fed in a collapsed state into the pipeline (10) via a first fluid sealing means (30) at the cable entry position (14). That device (62,64) maintains the cable end (34) centralised in the pipeline cross section whilst the cable (34) is fed into the pipeline (10). Magnetic sensing means (68,74,76) disposed near the cable exit position sense the presence of the cable end (34) and control the cable infeed so as to position the cable end (34) in a predetermined cable retrieval position. A tubular lance (54) is fed into the pipeline (10) through a second fluid sealing means (32) disposed at the cable exit position (16), and a grab (56) housed in the nozzle of the lance (54) is ejected to engage and capture part of the centralising device (62,64) and cable end (34), whereafter the grab (56) closes on being drawn back into the lance (54). The lance (54) is then withdrawn through the second fluid sealing means (32) so as to draw with it the grab (56) and the captured centralising device (62,64) and cable end (34).

Abstract: A discrete event simulation system that avoids all blocking and advances the simulation time in an efficient manner by treating the simulated system as a set of subsystems and simulating the subsystems concurrently. The simulation proceeds iteratively by restricting the simulation of scheduled events for each subsystem at any one time to a chosen simulated time segment (bounded lag) beginning with the lowest simulation time found among the subsytems. With each simulation iteration, an "at risk" demarcation time is evaluated based only on a subset of the subsystems that can potentially affect the simulation at the considered subsytem. Events scheduled for a time earlier than the "at risk" time are simulated. In simulating systems where some subsystems affect other subsystems only through intermediate subsystems, opaque periods can be experienced when, because of the specific process that is being simulated, such an intermediate subsystem "promises" that a particular route maintaining from this subsystem would be busy for a set period of time, and thereby also "promises" that no other subsystem can use this route as a conduit to affect other subsytems. That tends to push forward the "at risk" demarcation time.

Abstract: A monolithic transformer comprises two windings (14, 16) arranged in substantially a single plane with conductors of the windings interleaved with and crossing one another, whereby each winding is symmetrical about a line (A,A) passing through center points (CP,CT) of both of the windings, to which a center tap connection can be made. The conductors of the windings and crossings (18,20,26,28) therebetween can be arranged so that adjacent conductors belong to the different windings for maximum coupling. An unbalanced circuit can be connected between the center tap and one end of a winding, the other end (46) electrically floating, to compensate for the effects of the unbalanced circuit on interwinding capacitance. The transformer can be constructed using air bridge technology with conductors supported by and spaced from a surface of a substrate.

Abstract: A hot electron transistor (HET) comprising features that can result in substantially improved device characteristics is disclosed. Among the features is a highly doped (typically more than about 10²⁰cm⁻³) thin base region, a thin (typically less than about 100 nm) collector depletion region, and a highly doped (typically more than about 10¹⁹cm⁻³) collector contact region. Hot electron transport through the base region is possible, despite the high doping level, because the inelastic scattering rate can be relatively low in at least some highly doped compound semiconductors such as GaAs, AlGaAs, InGaAs, or InP. The elastic scattering rate in the base region also can be relatively low if the dopant atoms have an appropriate non-random distribution. Techniques for achieving such a distribution are disclosed. Transistors according to the invention are expected to find advantageous use in applications that demand high speed, e.g., in repeaters in high capacity optical fiber transmission systems.

Abstract: Polarization-maintaining coupler is made by a biconically-tapered-fused process from two short lengths of an optical fiber, each having a small, oval stress-applying region that substantially contacts the core. The area of the stress-applying region of the optical fiber is less than 10 percent, preferably less than 2 percent, that of the optical fiber and preferably is contiguous with the core. Couplers of highest quality are made from quartz glass fibers having a birefringence between 1 and 3 x 10⁻⁴. It is believed that the principal axes of the oval stress-applying regions of those couplers of highest quality have been collinear or parallel. To permit a coupler to be handled, it can be mounted on a quartz glass substrate with the coupler suspended in air and then potted in a cured elastomer.
