Abstract: Ozone is a strong oxidising agent having a wide range of applications in water treatment and in chemistry in general. Ozone is produced in ozone generators by silent electrical discharge. The starting gas used is air or oxygen. Since only a small proportion of the oxygen used is converted in the ozone generators to ozone, it is imperative in ozone production from oxygen for reasons of cost to recover the oxygen not converted to ozone and again pass it into the ozone generator. This can be achieved in adsorption plants by means of silica gel. In an adsorption phase, the ozone is adsorbed under elevated pressure while the oxygen flows back to the ozone generator unhindered. In a desorption phase, the ozone is discharged from the adsorption plant under somewhat reduced pressure. In order to be able to work continuously, reversible adsorption vessels are used. The process is also used in ozone production from air by carrying out an additional adsorptive nitrogen/oxygen separation. Desorption is carried out by means of a carrier gas, which dilutes the ozone discharged and may contaminate the adsorption material. As a result of ozone dilution, more liquid is required for complete ozone dissolution than would usually be necessary. In order to avoid unnecessary ozone dilution and contamination of the adsorption material, desorption is carried out at subatmospheric pressures with the additional use of a machine producing reduced pressure and a streaming medium. The machine is preferably an injector (10) through which the streaming medium flows and which sucks in the ozone which is mixed with the streaming medium and may be dissolved in it. The ratio of ozone and streaming medium can be set to an optimum value in each case. If the streaming medium is a gas, it is also possible to use any other machines producing reduced pressure by combining the lines for ozone and for gas at the machine inlet. <IMAGE>

Abstract: An altitude preselect apparatus for use with, or incorporation into, an automatic flight control system combines the incremental altitude signal from a pneumatic encoding altimeter (26) with a vertical speed computation to generate a smooth, continuous instantaneous altitude signal. A vertical speed reference signal is generated (44) to control the vertical flight path of the aircraft when the instantaneous altitude reaches a prescribed proximity to a desired flying altitude which is manually selected by the pilot (32, 33, 34). The apparatus initiates a capture sequence to hold the aircraft at the desired altitude once it is reached.

Abstract: A direct-current electric motor (29) used for, for example, positioning a printing device in an office machine, is controlled by an arrangement comprising a microprocessor (40) which causes the motor digitally to perform accelerations and/or decelerations to maintain it close to a desired speed programmed in relation to the distance to be completed. Control between the actual speed of the motor and the desired speed is effected utilizing the timing signals (FTA, STB) generated by a transducer (35) connected to the motor. During a first phase, the microprocessor compares the times taken to complete a series of angular steps of rotation, the steps following a schedule of decreasing size with stored reference times and effects accelerations and decelerations of durations proportional to any discrepancies. Once the motor is near enough to its target position to be on a monotonic segment of one of the timing signals (FTA) which is sinusoidal, control switches to a position feedback loop bringing the motor to a standstill with FTA zero.

Abstract: A cruise speed control system for an aircraft in which small differences between a target Mach command and the actual Mach number of the aircraft are used to displace the aircraft from its reference altitude either to increase or decrease actual Mach number in the short term. Long term differences are corrected through a special isolation filter (53) to separate the engine control loop and pitch control loop dynamics, and an integration technique (52) to adjust the automatic throttles about a thrust target for the commanded Mach. Large differences between the target Mach and the actual Mach, or large changes in the commanded Mach, are compensated for by non-linear gain means (72) which effectively increases or decreases the target thrust to cause the aircraft to accelerate or decelerate to the commanded Mach.

Abstract: A wraparound closure with closure means which can be easily re-opened, such as a zipper or Velcro-type closure, provides environmental protection for splices or branch-offs in elongate substrates, such as communications or other cables, which closure has the advantage that it can be opened and re-closed easily and quickly. The end portions of the closure are sealed around the cable substrate with a sealing material having a cone penetration value of 100 to 350 (10 -1  mm) and an ultimate elongation of at least 200%. The wraparound may include a retaining means, such as a resilient plastic ring, which may be positioned to hold the wraparound closure away from the cable substrate when the closure is opened and work is being performed on the cable and may be positioned around the cable to provide support for the wraparound closure when it is in the closed position. The sealing material is attached to the inside of the end portions of the wraparound with a neoprene rubber adhesive to assure that the sealing material adheres to the wraparound and releases from the cable when the wraparound is removed from the cable substrate. The sealing material is also pre-formed into an appropriate shape for sealing between cables in a branch-off configuration.

Abstract: A sloping roof structure comprises a supporting structure (72) and a plurality of elastically flexible, outwardly convexly curved roofing plates (74) mounted thereon. The roofing plates are mounted in a partly overlapping relationship so that the lower rim portion of each plate overlaps the upper rim portion of an adjacent lower plate. Each roofing plate is fastened to the supporting structure by means of nails (75), screws or other fastening means at a portion intermediate of the upper and lower rim portions of the plate. The initially curved plate is fixed in an at least partly flattened condition, whereby the upper and lower rim portions are resiliently pressed against the supporting structure (72) and the outer surface of the adjacent lower plate, respectively. The curved roofing plates (74) for such a roof structure may be made from a layer (37) of a plastic, deformable material, such as a cement mixture which may be reinforced by fibers. This layer of material may be placed on a curved supporting surface (70) so that the layer of material attains a shape similar to that of the supporting surface. The layer of material may then be hardened or set while supported by the curved supporting surface.
