Abstract: The present invention relates to means for controlling and for cutting the weft threads in looms with weft inserters. The combination of the means for controlling and for cutting the weft threads comprises a thread cutter carried by the loom framing, as well as a threader and a lowering hook carried by the sley. The thread cutter is constituted by a vertically-movable knife which co-operates with a component provided towards the rear with a weft thread retaining hook. The knife has, towards the rear, an extension for guiding the weft thread into the shed. The threader is formed by a horizontal ramp ended at its rear by an upwardly and forwardly open loop, located above the path of the entry needle, while the lowering hook may adopt, selectively, a high position above the weft thread portion connecting the threader loop to the cloth and a low position in which it presses down and holds one point of said weft thread portion below the path of the nippers of the entry needle.

Abstract: Exhaust gas is sampled from an internal combustion engine operated disconnected from the transmission elements, thus braked by its inertia and internal losses only.Before running the test it is important to find out the positions, at which the fuel supply means ensures idle running and maximum fuel supply, respectively. A monitoring device is designed to find out these positions, and then to run a test cycle between those positions. The monitoring device may include means for running, prior to the actual test, a short conditioning program at the engine, to ensure that the same has attained a desired normal temperature, when the test starts.

In order to maintain a suitable temperature for the active carbon the air is brought to pass through, or around the motor. A thermal relay is provided to interrupt the current supply to the motor, should the temperature, due to clogging of the mechanical filter and resulting increase of the motor output, be raise to an impermissible level.

Abstract: A low transport vehicle has a platform carried by a number of wheels arranged in a transverse row, hydraulic means being provided to raise and to lower the platform. In order to prevent a tilting of the cargo during voyage with the platform with respect to the wheels in raised position, the hydraulic system is arranged in such a manner that a ram operating an outward wheel in the row may be blocked-off from the system if the pressure in the system at the opposite end of the row falls below a predetermined value.

Abstract: An automotive power plant includes three turbine rotors, of which one forms a spool together with the compressor, and the other two rotors are interconnected by a gearing. The first turbine rotor is undersized, and cannot provide the necessary power for driving the compressor at full load, although the spool does not have to drive any internal auxiliaries. A slim shaft, carried in air bearings and rotating at supercritical speed, also when the plant is idling, transfers power from the gearing to the compressor spool.The turbine casing is die-cast of a light metal alloy, and is internally clad with pre-formed ceramic insulation components, bonded to the metal walls. In a front drive vehicle the casing is mounted in arcuate guides having their centers at the vehicle wheel axles, whereby the casing may be swung about 90.degree., when the gas turbine is to be serviced.

Abstract: A method and apparatus for reducing pollutant emissions from a source of combustion while simultaneously increasing the combustion efficiency. In a preferred mode, the technique contemplates the separation, removal and collection of positively charged species at the combustion zone. This is achieved by applying a relatively small magnitude electrostatic field at the combustion zone via positive and negative electrode means. A negative electrode may be positioned adjacent aperture means formed in the sidewall of the combustion chamber at the combustion zone so as to attract positive ionic species that include the pollutant emissions (e.g., NO.sup.+) desired to be extracted. A negative electrode may also be electrically connected to a tube that serves to collect the pollutant for later processing to a useful by-product (e.g., nitrogenous fertilizer).

Abstract: A ship's docking plant includes a floating platform, partly enclosing a vertically displaceable docking member, providing large working areas around the same, when in raised position. The docking member is retained in relation to the platform by a vertical guide means at the inward, transverse side of the docking member, said guide means permitting the docking member to obtain various angular positions with respect to a horizontal plane, in the longitudinal, as well as in the transverse direction. The docking member is, along its longitudinal sides, connected to the platform by means of reversible chain winches, permitting an adjustment of the position of the docking member in relation to a horizontal plane, when lowered down.

Abstract: A framework carrier adapted to move railway waggons outside a railway yard includes two first, longitudinal beams, each carrying a rail and two second, transverse beams adapted to co-operate with a transporting member, said transverse beams being adapted to locate the rails upon the carrier in alignment with the rails of the tracks, when the carrier is brought to rest against fixed stops at the track heads.

Abstract: When burning black liquor obtained during cellulose pulp manufacture it is desirable to maintain a constant atomizing pressure. Mere throttling of the liquor supply in order to adjust the combustion to actual heat demand will alter the spray pattern. A pressurized gaseous fluid is injected into the liquor supply conduit, and the amount of this gaseous fluid is governed in response to the actual heat demand. A monitoring device senses the pressure in the supply conduit downstream of the throttle valve, and adjusts the position of the latter in response to the activity caused by the gaseous fluid, so the resulting pressure is maintained at the desired level.

Abstract: This spinning machine weighs about 10 lbs. and is of about the size of a one foot cube. The reel on which the spun yarn is to be stored is contained within a large horizontal tube. The yarn is fed through a hole in the wall of the tube from a groove on the outer surface. The reel is rotated by running on the inner surface of the tube which is driven by, for instance, a sewing machine motor. By control of dimensions or by braking a relative speed is imposed between the reel and the tube and is the speed for reeling yarn. The yarn is fed to the groove from two small tubes, one stationary and the other rotating with the large tube. Both are coaxial with the large tube. Locks or sliver to be spun are presented to a surface with saw-tooth corrugations alternating with slots, and is fed to the stationary small tube.
