Abstract: ABSTRACT      A tube which may be employed as a sound suppression device and/or an exhaust ejector in the same or separate housings has inlet and outlet ends with a constricted portion between its ends and bypass passages through the constricted portion, within the tube, to permit a portion of the gas flow therethrough to bypass the constriction. The constricted portion may be circumferentially dis-continuous, and the passages may be located between the discontinuities.  The constricted portion may have a cross-sectional area that decreases to a minimum and then increases more gradually to a maximum toward the outlet end of the tube.

Abstract: METHOD FOR AROMATIZING SOLUBLE COFFEE                    ABSTRACT An improved method for aromatizing soluble coffee is described which results in a higher fixa-tion of grinder gas aromas on a glyceride substrate and an improved quality jar aroma.  The method involves liquid-liquid contact of the water phase, normally drained from equilibrated grinder gas and discarded, with a glyceride to recover valuable coffee aromatics in the glyceride.  Further, reflux of liquid carbon dioxide is used to recover yet more valuable coffee aromatics in the glyceride.  A 25 to 70% increase in aromatic yield is realized with an improvement to the aromatic quality of the aromatized glyceride and thereby the aromatized soluble coffee.

Abstract: A B S T R A C T            A hydraulic shock absorber includes a generally vertical cylinder receiving therein hydraulic liquid, a piston working in the cylinder and partioning the inte-rior thereof into two liquid chambers,an upper and a lower chamber. Two sets of one or more damping force generating check valves are mounted on the piston, one set generating the damping force in the expansion stroke and another set allowing free flow from the lower (2) to the upper (1) chamber in the compression stroke. A piston rod is secured to the piston extending through the end of the cylinder to the outside. Said sets of valves constitute connections between the two liquid chambers (1,2), a liquid reservoir (3) connected to the lower liquid chamber (2) by a third set of check valves generating the damping force in the compression stroke and allowing a return free flow from the reser-voir (3) to the lower chamber (2) in the expansion stroke.            An improved damping control is achieved by a circuit (10) forming a connection between the two liquid chambers (1, 2), a further circuit (9) connecting the reservoir (3) to the lower liquid chamber (2), each of the two circuits (9, 10) including a controllable first check valve (C1) and second check valve (C2), respect-ively, that can each take two states of operation under the action of a control means (20), in a first state locking the valve in a closed position cutting off the forward flow (E1 and E2 respectively) through the check valve (C1 and C2 respectively), and in a second state allowing a free forward flow (E1 and E2 respectively) through the check valve (C1 and C2 respectively), whereas the check valve (C1, C2) in the first state as well as in the second state block the reverse flow (D1 and D2 respectively) of both circuits (9, 10).

Abstract: ABSTRACT OF THE DISCLOSURE             The adjusting device possesses a hydraulic cylinder in whose cylinder tube there are housed a main piston equipped with a piston rod, an auxiliary piston and a force-exerting spring.  The cylinder tube is closed off at both of its ends by an associated end flange.  The outer surface of the cylinder tube simultaneously constitutes the guide surface of a guide tube which is fixedly connected by means of a connecting flange with the piston rod.  Since the cylinder tube possesses an essentially constant or uniform inner diameter and outer diameter, the guide tube can be constructed to be so long that the adjusting device is stable enough to serve as a supporting column or pillar, e.g. for a chair or other seat structure.

Abstract: Samples taken automatically and frequently from the outlets of silos 4 in mixing installations, e.g. for fodder mixtures, are brought unwrapped and successively to an automatic NIR analysis station 72, 26 through a pneumatic conveyor system with substantial common pipe lengths between said station and the individual samplers 34. The associated risk of contamination of the samples is counteracted by taking out and conveying sample portions which are much larger than is required for analysis itself, and the large sample portions are not wasted, as they are returned to their silos of origin through another pneumatic conveyor system 90. It is thus possible to operate with true on-line analysis and thus, with computer support, to effect necessary changes in the mixture recipes almost immediately in response to deviations in the analysis results. Various specialized sample-handling equipment for assisting operation is disclosed. <IMAGE>

Abstract: In order to obtain substances that are optically transparent in the infrared range, usable in the manufacture of optical fibers or radiation emitters, a metal or metalloid chalcogenide other than an oxide is produced by a double-substitution reaction between a starting chalcogen compound-particularly a hydride such as H2S, H2Se or H2Te-and a salt of the desired metal or metalloid, e.g. a chloride. The starting compound and the reactant salt preferably are vaporized at a temperature below the melting point of the resulting metal chalcogenide which thereupon precipitates in the reaction chamber.
