Abstract: At the start of web joining, braking power is strengthened to thereby reduce the speed of an old shaft, and, at this time, a pay-out roll is brought into a freely running condition. A second motor is instructed to run at a speed equal to a value of correction for tension plus (a line speed - a pay-out speed), and an accumulator roll unit starts moving simultaneously with the speed reduction of the old shaft. At the time of start of a new shaft, the pay-out roll is accelerated to (the line speed + a catching-up speed) at a constant rate. When the accumulator roll unit reaches a synchronizing position, a catching-up speed is reduced to zero to thereby synchronize with the line speed.

Abstract: PCT No. PCT/GB91/01250 Sec. 371 Date Apr. 17, 1992 Sec. 102(e) Date Apr. 17, 1992 PCT Filed Jul. 25, 1991 PCT Pub. No. WO92/02452 PCT Pub. Date Feb. 20, 1992.Process for producing dinitrogen pentoxide (N2O5) consists of reacting a solution of dinitrogen tetroxide (N2O4) in a volatile organic solvent, with a stream of an ozone-containing carrier gas. N2O5 produced by reaction between the N2O4 and ozone is transferred into the gas stream, and is thereafter condensed out of the gas stream by contact with further inert organic solvent. The latent heat of formation of N2O5 is absorbed by the heat of vaporization of the solvent, so limiting increases in reaction temperature and suppressing the dissociation of the N2O5. In a preferred embodiment the reaction and absorption steps are performed in separate columns having organic solvent recalculating continuously through each with carrier gas flowing continuously from the reaction column to the absorption column.

Abstract: An apparatus and method of contacting a liquid with different gases sequentially in separate mass transfer zones within a single vessel, the mass transfer zones operatively connected in liquid communication with each other, including intimately contacting the liquid with a first process gas in cocurrent flow in a first mass transfer zone to effect mass transfer between the first liquid and the process gas, and introducing the liquid into a second mass transfer zone with a second gas, different from the first gas, in cocurrent flow with the second liquid, thereby effecting mass transfer between the second liquid and the second gas. The rate of flow of the liquid from said first mass transfer zone to second mass transfer zone and recirculation to the first mass transfer zone is motivated by the difference in density of the contents of the liquid phase portion of each mass transfer zone and a following liquid downcomer or flow channel connecting it to the next sequential mass transfer zone, such that after passing through the last mass transfer zone, the liquid recirculates to the first mass transfer zone. The apparatus and method are ideally suited to carrying out the process of hydrogen sulfide removal from gases by means of an air-regenerated liquid redox catalyst, such as chelated iron.

Abstract: A computer system for generating and representing contour lines of a saddle surface is described. Contour lines are produced by the intersection of the saddle surface with a plane. Depending on whether the plane of intersection is arranged above or below a saddle point of the saddle surface, two different contour lines are produced in each case. The height of the saddle point can be used by the computer system for deciding which of the possible contour lines are the correct ones for the respective case. The contour lines are defined in the form of in each case two points of intersection, associated points of intersection being stored in pairs in the computer system. Neighbourhood relationships which specify the associated neighbour for each point of intersection are determined by rearranging, exchanging, combining and so forth these pairs of points of intersection. The computer system can use these neighbourhood relationships for representing the polygonal contour line courses assembled from the contour lines, for example on a screen. <IMAGE>

Abstract: It is known to utilize athermal mounts for laser apparatus. Such mounts may include a thermo-electric cooler and a temperature sensor which is located between the laser device itself and the cooler. However, due to the thermal resistance between the sensor and the laser device, as well as the thermal mass of the assembly, it is not possible to compensate for rapid changes in temperature of the laser device. This means that the laser device cannot be maintained in its correct operating temperature range. Described herein is an improved athermal mount for a laser device (10) which includes a thermo-electric cooler (32) with a thick film hybrid chip positioned between the cooler (32) and the device (10). The chip incorporates areas of temperature-sensitive material which produce electrical signals corresponding to the temperature. Processing means (36) process these signals to determine whether the cooler (32) needs to be adjusted to correct any variation in temperature of the device (10) outside its permitted operating temperature range.

Abstract: In dual-sensor, bottom-cable (16) marine seismic exploration where hydrophone/geophone pairs (18) are deployed on the marine bottom (20), coupling imperfections between the geophones and the marine bottom contribute to differences between the impulse response of the geophones and the impulse response of the hydrophones. To correct for the coupling imperfection, a filter is designed which compensates for the inherent impulse response differences as well as response differences caused by the imperfect coupling. Preferably, the filter is designed using a calibration procedure prior to production shooting. First, the response of a hydrophone and geophone to a seismic wave is recorded. Then, these recorded responses are transformed into the frequency domain. Once transformed, the response of the hydrophone is divided by the response of the geophone to produce a filtering function. When the filtering function is applied to geophone signals during production shooting, the filter compensates the geophone signals to alleviate differences in response characteristics between the geophone signals and the hydrophone signals.

Abstract: A self-clocking glyph code (23) is provided for encoding n-bit long digital values (where n>1) in a logically ordered sequence of composite glyphs (31a-31d) that are written, printed, or otherwise recorded on a hardcopy recording medium in accordance with a predetermined spatial formatting rule. As used herein, a "composite glyph" is a graphical symbol that has a plurality of predefined, substantially orthogonal, graphical characteristics; each of which is capable of assuming any one of a plurality of predefined graphical states. An n-bit long digital value is distributively encoded in a glyph of this type by decomposing its n-bits, prior to or during the encoding, into a plurality of shorter, ordered, non-overlapping bit strings. The digital values of these bit strings, in turn, are encoded in the states of respective graphical characteristics of the composite glyph in a predetermined logical order, thereby preserving the logical ordering of the bit strings.
