Abstract: A stop mechanism for knitting machines of the Rachel type comprising a reed with an upper flange fitted with a strengthening section projecting from and along a whole edge for guiding a thread. A contact which is fixed for threads not forming a nap, and is movable and cylindrical for threads produces a nap. The reed has small plates and blade components between these plates. The blade components are bent to form a groove for guiding the thread. Each blade component has two circular holes and one elongated hole and the built-in tendency for toppling over onto this contact. The blade components and small plates are connected by two spindles. The contact may have a chordal flat for increasing its contact area and is attached to an electrical conductor at one of its extreme ends and can be moved along a semicircular path by a crank. A metal spindle attached to an electrical wire passes through the circular hole innermost on the blade component.

Abstract: The invention provides for a rotary valve of the type employed for transporting solid material between zones having a fluid pressure differential, with a minimum fluid leakage between the zones. The valve has a housing with a bore, passages communicating with the bore and designed to be coupled to the respective zones, and a rotor which is housed within the bore. The rotor is defined by an axial drive shaft, a pair of spaced end plates on the shaft and a series of radial vanes disposed between the end plates. The valve is formed with material deflecting formations on the peripheral surfaces of the end plates the formations being adapted for urging material inwardly into the zone intermediate the end plates upon rotation of the rotor in a predetermined direction.

Abstract: An arrangement for carding fibers to produce a fibrous sliver, in which the fibrous sliver is advanced through the nip between two rollers, and withdrawn downwardly from the nip through a compacting funnel in which the sliver becomes formed with a coherent ribbon. The fibrous sliver is withdrawn in a vertical path coinciding with a center line of the nip, or it may be withdrawn in a path which is inclined to the longitudinal end to a center line of the nip. The pair of nip rollers are positioned to receive the fibrous sliver so that the latter passes through the nip therebetween. The spacing between the nip rollers and a guide baffle is arranged to be greater than the spacing between the guide baffle and a pair of withdrawing rollers located downstream of the funnel.

Abstract: The densified area commonly formed during the manufacture of blocks of pliable polyurethane foam on a web of continuous material in a foaming tunnel is eliminated by controlled heating of the conveyor belt in the tunnel to a range between the densification temperature and the cracking temperature of the foam during the reaction period. An improved apparatus for this purpose comprises an enclosed, insulated housing and means for heating the conveyor belt such as hot air, infrared radiation, steam coils or electrical resistors. A preferred embodiment comprises heating the bottom of the foam block after it emerges from the foaming tunnel to a temperature considerably higher than that in the foaming tunnel. This eliminates completely any need for trimming off irregularities after removal of the web of continuous material.

Abstract: A blade of the fan wheel of a diagonal-flow fan, which blade should ideally have a shape of a twisted double-curvature or undevelopable surface, is formed from a portion of a combination of a cylindrical plate and a planar plate tangent to the cylindrical plate or of a combination of a pair of mutually circumscribing cylindrical surfaces, which portion constitutes a developable surface. To realize the formation of a blade from the developable surface, lines of intersection between combined cylinder and planar plates or combined cylinders and a number of coaxial imaginary conical surfaces representing streamlines in the fan wheel are used as a basis for design.

Abstract: The proposed method for automatic control of a power plant is as follows. A control signal of the electric generator's electric load is applied to a first control element which controls the flow of gas supplied from the gas line to the high-pressure section of an expansion engine. This controls the amount of gas directed from the take-off chamber of the expansion engine to the gas pipeline. A control signal to control the pressure downstream of the expansion engine is applied to a second control element to control the flow rate of the gas flow directed from the low-pressure section of the expansion engine to the controlled counter-pressure line. A control signal to control the pressure downstream of the expansion engine is applied to a third control element to control the gas flow rate, which is installed in the line that bypasses the low-pressure section of the expansion engine, whereby the rest of the gas flow is directed to the controlled counterpressure line.
