Abstract: Components, usually but not exclusively gaseous components, are removed in a liquid medium from gas streams and chemically converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition metal solution in a modified agitated flotation cell. A gas-liquid contact apparatus, generally a combined chemical reactor and solid product separation device, comprising such modified agitated flotation cell also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. In general, the gas velocity index is at least about 18 per second per opening, preferably at least about 24 per second per opening. Each of the openings has an area corresponding to an equivalent diameter less than about one inch.

Abstract: It comprises a dual-face printed circuit (1) comprising, on a first face (11), a circuit for inputting the signal to be modulated and a circuit for outputting the modulated signal, each formed by a strip line. A second face (12) of the printed circuit comprises a phase- modulation circuit (120) formed by a slot line (LF) formed by a junction (Y) and a loop connecting the symmetrical branches of the junction, the loop being denoted 1202. The first and second switching means (121, 122) are connected up to each symmetrical branch of the junction (Y) and separate means of control of the first (121) and second (122) switching means deliver an independent switching control signal (SCC) to these latter. Capacitors (Ci) uniformly distributed along the slot ensure that the two edges of the said slot are short- circuited. Application to the circuit for regenerating satellite and telecommunications signals and to two- or four-phase modulators. <IMAGE>

Abstract: With certain picture formats, for example, presentation of 16:9 picture on a 4:3 screen, the cut off signals for the dark radiation current regulation inserted into the video signal can become visible in the black bands. The task is to avoid such signals becoming visible on the screen. The measuring process for the cut off regulation only happens briefly, for example, always only shortly after switching on the receiver. The result of the measurement (Uco) is stored in a memory (14) and read out from the memory (14) during most of the operating time. In particular, color televison receivers for the presentation of differing picture formats.

Abstract: A web slitting machine (10) for cutting a web or roll of material includes an upper carriage assembly (16) joined to a lower blade holder assembly (18) by a selectively removable guide key (38) which is milled to provide a predetermined cant angle for the blade (20). The blade (20) is lowered into position by a piston (54, 58) which is rectangular and includes a torsion-resisting sleeve (60a, 60b) to prevent rotation of the piston about its vertical axis. A pneumatic control provides a plurality of control modes whereby the blade (20) may be raised and lowered with or without locking the upper carriage assembly (16) to its transverse bar (14) and vice-versa. A unique side shift adjustment is provided whereby the blade (20) may be shifted to a half-stroke position and the upper carriage (16) locked when the blade is positioned against a lower knife (22). This ensures that the pressure of the blade (20) against the knife (22) is the pressure exerted at the mid point of the stroke. A parallelogram linkage (210, 212) biased by a spring (224) can provide a shock absorber for maintaining blade/knife contact in the presence of webs moving at high speed. <IMAGE>

Abstract: In a method and apparatus for cutting either a single sheet or a lay-up of sheets of material (22) to derive pattern pieces (58) or the like from the material (22), the material is cut segment-by-segment (74,76,84,86,88) by bringing a fresh segment to a cutting station (26) after a preceding segment has been entirely cut. Discontinuities, which may translate into points of non-clean cutting, which might otherwise occur in cut lines (62) as they pass to one segment to another, because of accidental shifting or mispositioning of the material during advancement, are avoided or reduced by acquiring the start and finish X and Y coordinates of an index point (90) on the material (22) and then using such coordinates with the cutting instructions used in the cutting of the subsequent segment, the use of the coordinates being such that accidental shifting or mispositioning of the material is taken into account and compensated for in the cutting of the second segment. <IMAGE>
