Abstract: Bagless continuous ambulatory peritoneal dialysis comprising a valve (12) having first, second and third fluid ports (A, B, C). The first and second fluid ports (A, B) are secured to first and second fluid containers (54, 62) respectively, through tubing (48, 56) and connector assemblies (50, 52, and 58, 60). The third fluid port (C) is connected through tubing (64) to a catheter (70) implanted in the abdominal wall of a user, also through a connector assembly (66, 68). The valve (12) includes an actuator (38) moveable at least between four positions, a first position (fig. 6b) which all of the fluid ports (A, B, C) are blocked, a second position (fig. 6c) in which the second and third fluid ports (B, C) are interconnected, a third position (fig. 6d) in which the first and second fluid ports (A, B) are interconnected, and a fourth position (fig. 6e) in which the first and third fluid ports (A, C) are interconnected. The method employs the valve (12) to provide dialysis by reversing the fluid containers (54, 62) and the direction of movement of the valve actuator (38) for alternate cycles.

Abstract: The present invention relates to a method for controlling the thickness of an intermetallic layer (Fe-Zn phase) on a steel strip in a continuous hot-dip galvanizing line. The steel strip is rapidly cooled by quenching in a zinc bath and the structure of the coating to be formed on the steel strip is controlled by directing a flow of molten zinc, cooled to a temperature 1 DEG  to 15 DEG  C. below the operating temperature of the zinc bath, towards the steel strip. At least a part of said flow is preferably directed towards the steel strip close to its immersion point into the zinc bath, obliquely against the movement direction of the steel strip.

Abstract: Sepn. of H2SO4 and NHO3 from dinitrotoluene (DNT) produced by nitrating toluene with H2SO4/HNO3 is effected by (a) separating most of the H2SO4 and NHO3 from a DNT phase contg. up to H2SO4 and up to 5 wt. % HNO3; (b) mixing the DNT phase with up to 10 wt. % H2O; and (c) separating the aq. phase. The DNT phase is pref. mixed with 0.3-8 wt. % H2O at 65-90 deg. C.  Alternatively, the acids may be sepd. in two stages by mixing the DNT phase with 0.3-3 wt. % H2O, separating the H2SO4-rich aq. phase, mixing the DNT phase with 2-6 wt. % H2O, and separating the HNO3-rich aq. phase.

Abstract: Plants with a number of tanks producing adhesives and with their gases continuously purged with inert gas have a gas disposal equipment. The mixed inert gas-evolved gas is passed from all the tanks through a common pipeline with pressure control valve into a processing plant; the valve is regulated to maintain a constant gas pressure of 0.1-0.2 mbar. A feed pipe beyond the valve supplies a larger volume of air than that of the inert/evolved gas mixture, and a fan maintains a constant under-pressure of 3-4  mbar in the common pipeline beyond the valve. The valve is a pendulum non-return type. An annular housing contains a flap which revolves eccentrically above the centre line on needle bearings, these bearings engage correspondingly tapered holes in the rim of the flap, and they have segmental stops matching the eccentricity of the axis of the flap; the housing has a groove one each side to open the flap in one direction only, and an adjustable counter-weight is provided on the flap underneath the axis of rotation.

Abstract: The invention concerns a construction for controlled lubrication of one of a number of elements displaceable relative to one another by the movement of one of said elements. The proposed construction is used for lubrication to reduce wear and is applicable in numerous technical fields, for example craneways, elevator guide rails, cableways, and railways. The construction has a lubricant feeder (3) connected to the bore in one of the elements to be lubricated, advantageously in the stationary element, for example in the rail (1) - said bore being connected either directly or through a pressure pipe (7) to the surface exposed to the greatest wear - and to the lubricant container through a filling pipe (6). A cylinder connecting with a cavity provided with a suction valve (9) has a piston (11) which slides against a spring (17).

Abstract: The invention relates to a modulation circuit for a transponder. Said modulation circuit has non-linear components which are located between a switching transistor (M5) and coil terminals (LA, LB).

Abstract: It is generally known in relation to hydroelectric power stations that, before the water impinges on the turbine of the hydroelectric power station and there delivers its energy to the turbine, the water flows through a pipe. Depending on the respective nature of the hydroelectric power station that pipe can be a downpipe through which the water flows, according to the respective local factors, in dependence on the fall height and the amount of water. In one aspect of the invention, the flow speed of the water (fluid) can be adjusted in the region of the turbine. In one aspect, a turbine is arranged within a flow pipe. The turbine has a variable cross-section, and thereby, the through-flow cross-section within the pipe is variable.
