A semipermeable hollow fiber membrane (10) consists of a first layer (12) for selectively permeating only water and water soluble substances therethrough and excluding the permeation of hydrocarbon fluids and a second layer (14) covalently bonded to the first layer (12), the second layer (14) being selective permeable only to water soluble substances and excluding water permeation therethrough. Th...

PURPOSE: To carry out the waxing of a weft for a high-speed shuttleless loom by arranging a rove material or a felt strip in an inverted U-shape state in a paraffin oil container closed by a cover, absorbing the paraffin oil in the vertical parts, permeating the paraffin oil to a horizontal part and applying the paraffin oil through a filter medium to a traveling yarn. CONSTITUTION: A rove materia...

A gearbox for transmitting drive from the bowl of a decanter centrifuge to its screw conveyor comprises a double epicyclic gear train in which idler gears (G1) are inserted in the first stage between the sun (S1) and planet gears (P1) thereof to reverse the sense of rotation of the carrier (4) which is fast with the sun gear (S2) of the second stage, in order that the second stage carrier is rotat...

A yarn stripper device (10) for removing waste synthetic yarn from a tubular yarn holder (11), comprises a housing (13) having an inlet (14) for receiving the yarn holders (11), a traveller (34) engagable with the yarn holder (11) and operable to move the yarn holder along a yarn stripping path (16) in the housing, a rotary saw (18) arranged in the housing alongside the path (16) and operable to c...

A continously variable transmission for transmitting the power of an internal combustion engine (1) to driving wheels (19) of a motor vehicle, is described. The transmission includes a drive pulley (7) including a hydraulically shiftable disc (7a) and a first hydraulic cylinder (9a) for shifting the disc (7a), a driven pulley (8) including a hydraulically shiftable disc (8a) and a second hydraulic...

A control system for an infinitely variable transmission has a line pressure control valve having ports and a spool for controlling the line pressure of oil supplied to a cylinder of a drive pulley to change the transmission ratio. The line pressure control valve has chambers. By controlling the pressure of oil supplied to the chambers in accordance with a desired line pressure, the spool is shift...

A control system for a continuously variable transmission has a line pressure control valve having ports and a spool for controlling the line pressure of oil supplied to a cylinder of a driven pulley to change the line pressure. The line pressure control valve has chambers at opposite sides of the spool. A spring is provided between one end of the spool and a spring retainer. By draining the oil s...

A control system for a motor vehicle provided with a continuously variable transmission. The transmission has a line pressure control valve having ports and a spool for controlling the line pressure of oil supplied to a cylinder of a pulley device to change the transmission ratio. When torque of an engine is rapidly increased, the line pressure is increased so as to prevent a belt of the pulley de...

A control system has a transmission ratio control valve having a spool for controlling oil supplied to a cylinder of a drive pulley to change the transmission ratio. By controlling the pressure of oil supplied to one end of the spool of the transmission ratio control valve in accordance with conditions of the engine and transmission, the spool is shifted, so that the rate of change of the transmis...

The invention relates to an apparatus for the production of cast metal strip of amorphous and/or compact grained structures. To enable the strip to be coiled on reels at high strip speeds, the strip 6 is guided at the outlet of the casting apparatus 1-6 having a casting wheel 4 over a first and second strip guide channel. The first strip guide channel is formed by at least one cooling wheel 9, 11 ...

The (R) or (S) isomer of acetorphan or N-/2-acetylthiomethyl)-1-oxo-3-phenylpropyl/(S) alanine methyl ester is prepared by splitting of racemic acetylthio-2-benzylpropanoic acid by reaction with ephedrin, separation of the enantiomeric salt obtained, then freeing of the acid and coupling with the corresponding amino acid ester. The obtained preparations possess remarkable therapeutic activities an...
