Abstract: ABSTRACT OF THE DISCLOSURE          The useful life  of a turbomachine part is affected by cyclic stresses which occur in the turbo-machine part as a result of heating and cooling the turbomachine part.  Each thermal cycle is comprised of a maximum heating stress and a maximum cooling stress which may occur during turbomachine start-up, load changes, shut-downs, or boiler excursions.  The maximum heating stress and the maximum cooling stress for each cycle may be combined to define a stress range.  The actual strees range for each cycle is compared with a calculated stress range curve for the turbomachine part to determine the amount of life expended during the cycle for the turbomachine part.  This value may be expressed as a percent of life expended for the cycle.  The life expended for each cycle is accumulated to provide an output indicative of the total percent life expended for the turbomachine part according to its operating history.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to rockers for mounting on the legs of chairs to convert the chairs to rocking chairs.  The rockers are adaptable to be mounted on chairs having different spacings between the legs thereof, and to be mounted on chairs the bottoms of whose legs are connected by bars.  The rockers are also adapted to be releasably or permanently mounted on the chairs.  To fulfill all these functions, the inventive rocker, which consists of an arcuately shaped elongated member, has elongated openings adjacent the front and rear ends and on the top surface thereof.  The elongated openings receive the legs of normal chairs.  Extending across the width of the rocker, and over the elongated openings, are grooves which can receive the bars of chairs whose legs are connected by bars.  As the openings are elongated the rockers can be mounted on chairs with diff-erent lengths of spacing between their front and rear legs.  As chairs with bars are usually of the folding type, the chairs can be folded to fit the spacing between grooves.  However, two grooves can also be provided at the rear of the rocker so that the rocker will fit a wider range of such chairs.

Abstract: ABSTRACT OF THE DISCLOSURE          An impact printer of the dot matrix type capable of printing in either the forward or reverse direction. Means are provided for determining the position of the print head at any given instant. Upon completion of a line of print the print head is abruptly halted. The next line of characters is examined to determine the end points of its character field. Comparisons are made to determine whether the print head lies within or beyond the end points. In cases where the print head lies beyond the end points of the character field, the printing occurs by moving the head in a direction toward the closest end point and then printing. If the print head occupies the location between the end points the position of the head is loaded into a pair of counters which are simultaneously counted up and down respectively. The outputs of the counters are continuously compared against the values representing the end point locations whereupon the first favorably comparison determines the shortest distance of print head travel for starting printing. High speed electronic circuitry is provided for storing data representing the next line to be printed in both forward and reverse formats whereupon the decision as to the direction in which data is printed automatically controls the appropriate storage medium.       Novel video detection means is provided both for de-termining the direction of head movement at any instant and for controlling the printing positions. The use of delayed strobes derived directly from the video control allows printing to start immediately from the rest position, and provides accurate registration of delayed strobes relative to strobe pulses regardless of the velocity of the carriage.

Abstract: ABSTRACT OF THE DISCLOSURE     In a process for eliminating impurities and undesirable components from gas mixtures by passing the mixture through an activated carbon-containing adsorber.  Sulfur compounds including hydrogen sulfide are eliminated by increasing the oxygen contents of the gas mixture which contains at least oxygen and/or sulfur dioxide in addition to the hydrogen sulfide to an extent that an oxygen hydrogen sulfide molar ratio is obtained in the gas mix-ture which is between about 1 : 0.45 and 1 : 0.65.  The process may also be carried-out with two groups of absorbers where in the first adsorber the elemental sulfur is eliminated in liquid form and where the remaining minor portion of sulfur in vaporous or mist-like form is then removed in the second group of adsorber or adsorbers by adsorption on the ac-tivated coal.  The purified gas is then recovered from the adsorber or with two groups of adsorbers from the second group of adsorber or adsorbers and the activated carbon is subjected to periodic regeneration cycles.
