Abstract: A centrifuge with a self-emptying drum has ejection openings in its jacket that lead out of a solids space and can be blocked off with a piston valve. It has a closure compartment that can be charged with closure fluid and is associated with the piston valve. Part of the closure compartment is divided into an upper and a lower division by a disk. Outflow channels lead out of the drum from the lower division of the closure compartment. The disk can be displaced axially. When it is in its lower position, it hermetically seals off the lower division of the closure compartment from the rest of the compartment. When it is in its upper position, into which it can be displaced hydraulically, the disk allows the lower division to communicate with the rest of the closure compartment so that closure fluid flows out of the compartment through its lower division and through outflow channels. Once a predetermined hydrostatic pressure has been attained in the lower division, the disk automatically returns to its lower position, terminating the outflow of closure fluid.

Abstract: Winnowing of shredded tobacco stem material, or other particulate tobacco material, is effected by metering the shredded stem material from a reservoir and then picking the metered flow to open and separate the particles one from another. The resulting stream of separated individual particles of shredded tobacco stem material is projected into an upwardly-flowing air stream to entrain a desired lighter fraction of the particles and carry it out of the separator device. The undesired heavy fraction falls in the separator device and is collected. The collected heavy fraction preferably is reprocessed to separate agglomerates of shredded stem material present in the heavy fraction into individual particles, which are then entrained in a second upwardly-flowing air stream which subsequently joins up with the first gas stream.

Abstract: A power brake booster, in which the valve piston is slidably supported in the control hub and cooperates with the poppet valve, that is formed of any rubber-elastic material. The poppet valve is designed as a cone valve. Thus when the valve passage is opened, atmospheric air enters the working chamber from the air chamber through the opening, that is arranged in the control hub transversely to the booster's longitudinal axis, to flow in almost undisturbed and without turbulence. To ensure a reliable sealing seat, the peripheral surface of the truncated-cone-shaped end of the valve piston is equipped with a curcumferential groove, the one lateral wall of the groove forming together with the peripheral surface a sealing edge which reliably abuts on the plane plate surface of the poppet valve when the valve is closed.

Abstract: An HVDC power transmission plant with a rectifier station and an inverter station interconnected by a d.c. power transmission line is disclosed. The plant has a communication link for transmitting control information between the stations, at least one of which having at least two parallel-connected converters. If protective blocking of a faulty converter is made in a faulty station during a period when the communication link is not available, the line voltage and line current are temporarily reduced to zero in the rectifier station. In the faultless station, this state is detected and the minimum value of the control angle of the converters of the faultless station is temporarily increased. After output from the rectifier station has been restored, the line current is measured and the current order in the faultless station is set at the measured value, taking account of the current margin. Thereafter, the minimum value of the control angle is reduced to its normal value, thereby restoring normal operation of the plant.

Abstract: Stable aqueous fabric softening compositions based on water-dispersible cationic fabric softeners such as the di-long chain, di-short chain quaternary ammonium salts are provided using synergistic proportions of fatty alcohols to enhance the softening performance. Both concentrated and ready-for-use formulations can be prepared. The active ingredients concentration in the concentrated formula is generally in the range of 11 to 20% by weight while for the ready-for-use formulations, concentration of the active ingredients may range from about 3 to about 8% by weight. In either case, the weight ratio of cationic softening agent to fatty alcohol being in the range of from about 4.5:1 to 3.5:1. These compositions have low viscosity and are easily dispersible in cold water and are storage stable. Water soluble electrolytes can further reduce viscosity and ethoxylated amines can further increase stability. Methods for making the compositions are also disclosed.

Abstract: To control the sludge concentration of a separated component, separated sludge is recirculated back to the separation chamber of a centrifugal separator at a controlled rate by letting the sludge pass through a channel formed such that the magnitude of the recirculated flow will be dependent on the sludge viscosity. If the viscosity of the separated sludge increases, the amount of recirculated sludge is reduced, and vice versa. The separator of the invention provides for such sludge recirculation within the centrifuge rotor itself. Arranged centrally in the rotor, in addition to a reception chamber (10) for separated sludge, is a recirculation chamber (14) to which sludge is transferred from the reception chamber (10). An overflow outlet (15) maintains a free liquid surface in the recirculation chamber (14) at a predetermined radial level. Recirculation channels (16), formed so that the flow therethrough will be controlled automatically according to the viscosity of the separated sludge, conducts sludge from the recirculation chamber (14) back to the radially outermost parts of the separation chamber (5).
