Abstract: Circuit arrangement comprising a parabolic generator (2) for supplying a periodic, substantially parabolic signal to an output terminal during the trace time and an arcuate signal generator (3) for supplying an arcuate signal, which has the shape of, for example, half a sine wave, during the retrace time. At the start of the retrace time the arcuate signal and its derivative are given values which are substantially equal to the corresponding values of the parabolic signal at the end of the trace time. The arcuate signal generator is adapted to generate the arcuate signal in a time-discrete manner under the control of switching pulses supplied by a pulse circuit (4). The pulse circuit (4) is adapted to supply such a constant number of switching pulses for generating the arcuate signal at a variable retrace time that the arcuate signal and its derivative assume values which are substantially equal to the corresponding values of the parabolic signal at the start of the trace time.

Abstract: The gas flow valve enables constant venting and is used with a cuff (3) showing a rapid decrease in venting ability at a predetermined value on a boundary within the pressure range which allows measurement of blood pressure. The gas flow valve has a body (1) made of an elastic material and comprising a wedge-shaped portion formed integrally with a mounting base (1a) so as to have a flat portion with upper and lower surfaces (1b) serving as pressure-responsive surfaces, a linear opening formed at the tip of the wedge-shaped portion, and a passageway (1c) communicating with the opening (1d) and extending in the longitudinal direction within the mounting base and the tip portion. A thin sheet-like member (2) is twisted and disposed in the passageway so that the tip portion (2b) is held by the opening (1d). As a result, the elastic deformation of the gas passageway formed by the gaps in the opening during pressure reduction is promoted by the resiliency of the torsion of the thin sheet-like member. A sphygmomanometer air-feeding/discharging apparatus with the gas flow valve has flexibility for cuffs having various shapes and specifications and enables easy adjustment of the orifice area.

Abstract: An improved method of presulfiding a hydrotreating or hydrocracking catalyst which minimizes sulfur stripping upon start-up of a hydrotreating or hydrocracking reactor utilizing such a catalyst. The method comprises the steps of contacting a hydrotreating or hydrocracking catalyst with elemental sulfur at a temperature below the melting point of sulfur, thereby forming a sulfur-catalyst mixture, and heating the sulfur-catalyst mixture to a temperature above the melting point of sulfur. Preferably, the sulfur-catalyst mixture is first mixed with at least one member selected from the group consisting of high boiling oils and hydrocarbon solvents to form a prewet mixture prior to heating at a temperature above the melting point of sulfur. Tail gas treating catalysts are also presulfided by these methods.
