Abstract: Apparatus for straightening distorted weft threads comprising a number of flexible rods (1) which form a roller shell (2) around a shaft (3). In the center of the roller shell (2), the rods (1) are connected articulatedly with a disk (5) disposed on the shaft (3) and are thereby held at a certain diameter in this region. In the region of the sides of the roller shell (2), the rods (1) are hinged via load levers (7) to sleeves (11) displaceable on the shaft (3). Via a driven spindle (15), the position of the sleeves (11) and hence also the form of the roller shell (2) can be changed.

Abstract: The operating condition of sliding components inserted between a slide or sprocket chain and a guide system for such chain is continuously monitored by an electrical loop conductor which passes through a plurality of sliding components. The electrical conductor is provided with an electrically insulating jacket which is preferably also heat resistant. The loop conductor is inserted into a monitoring circuit including a relay for activating an alarm when the loop conductor is either interrupted or when its insulation is damaged. This happens when any one of the sliding components through which the loop conductor passes, are sufficiently damaged. The alarm signal may also be used to stop the further drive of the sprocket chain.

Abstract: A transport cart for material carriers such as bobbins or drums having threads or other elongated material wound thereon, has a cart frame with wheels and a tilting frame journalled in said cart frame. The tilting frame carries two parallel skids for supporting a material carrier on its rollers. The tilting frame is tiltable between a first position in which the skids extend horizontally for loading a material carrier onto the cart, and a second position in which the skids extend vertically for unloading a material carrier, or vice versa.

Abstract: A cylindrical container (1) is horizontally arranged with its longitudinal axis. The container is subdivided by a flexible membrane (5) into a larger chamber (6) for holding textile material, preferably in a receptacle (3), and dyeing liquor, and a smaller chamber (7) for a pressurized gas. An excess pressure necessary for the high-temperature dyeing process is maintained in the smaller chamber (7) to compensate for changes in the liquor volume. These changes are temperature dependent. It is sufficient if the volume of the smaller chamber (7) is smaller than one-tenth the volume of the larger chamber (6).

Abstract: Knitware in hose form is prepared for a wet treatment, a preliminary dewatering, and for drying, by winding the hose into wound laps under a constant winding tension, so that the laps have a density of more than 200 and less than 400 g/dm.sup.3. The lap is coaxially compressed to reduce its original axial length by 3% to 8% and in this state the lap is exposed to dye liquor, flowing, for example, alternately radially inwardly or radially outwardly or axially in alternate directions. The lap is then preliminarily dewatered in an unvaried state, preferably by rotation. Thereafter, the lap is subjected in the same state to a drying treatment. The drying treatment may, in the alternative, be performed after the knitware has been unrolled and the hose has been cut lengthwise for securing the knitware in its spread-out state to a tentering frame which is then passed through a drying chamber.

Abstract: An apparatus for the treatment of a textile web supported on a tenter by contact with a heated treatment medium is disclosed. The apparatus includes a nozzle box or boxes having openings directed toward a fabric web to be treated. A by-pass opening is provided for conducting the treatment medium from the compression to the suction side of a circulating apparatus. The cross sectional area of the by-pass opening is substantially identical to the total of the cross sectional areas of the nozzles of the nozzle box, whereby the flow resistance of the treatment medium is independent to whether flow is through the nozzle openings or through the by-pass opening or some combination thereof.

Abstract: The links (1) of a chain such as a tentering chain are respectively connected to each other by pins (6). In order to secure the pin against rotating and against axial shifting, an end of the pin (6) protruding beyond an outer surface of a lug (2) of the chain link (1) is provided with a radial bore (7) into which one prong (8) of a two pronged spring clip element (9) is inserted. The other prong (10) of the spring clip element (9) partially encircles the protruding end of the pin (6). A shoulder (14) projects from the outer surface of the lug (2) and a groove (13) extends into said shoulder so that a bottom (12) of the groove (13) forms a stop surface perpendicular to the lug plane. One end (15) of the one prong (8) and a transition part (11) between the two prongs (8, 10) rest against the stop surface for securely holding the spring clip element in place.

Abstract: For a method for heat-treating textile material, and for a tenter for carrying out the method, it is proposed to control the textile web velocity as a function of the point on the treatment path at which the maximum deviation in the amount of energy spent per unit time occurs. To determine this point on the treatment path it is not necessary, therefore, to measure the momentary temperature of the textile material directly or the temperatures of the treatment medium flowing in and out. Instead, it suffices to determine the individual valve positions which indicate the amounts of energy supplied per unit time, and to infer therefrom the site of the treatment path where the drying process is completed and the fixing process sets in.

Abstract: A fabric treatment apparatus for advancing a web of fabric through a bath while spreading deflecting and squeezing same is disclosed. The apparatus includes a moveable trough for the treatment liquid and a displacement body which is completely submerged in the trough in the operative condition of the apparatus, the displacement body also functioning as a heat exchanger.

Abstract: Angular sections form frames which can be fitted together in the frame plane in modular fashion. Legs of the sections are formed so that through two interconnected legs of adjacent frames notches of T-shaped cross-section result, into which hammer head-shaped ends of pull rods can be introduced. By means of the pull rods, ledges can be pressed against filter and/or light fixture housings, which in this manner are pressed against legs of the profiles on the opposite housing side, adjacent frames thus make it possible in a correspondingly compact model to attach filters and light fixtures without the distance between two adjacent filters or between a filter and a light fixture occupying a width that would impair the flow profile of the air issuing from the filters.

Abstract: The pin-nipper chain consists of holders detachably secured on links and is composed of two holder parts of U-shaped cross section. On the underside of one of the holder parts a slider is detachably fastened in a sheetmetal part. On an inner side of the other holder part a slider is enclosed, likewise detachably, also in a sheetmetal part. The other holder part is exchangeable for a holder part which is provided, instead of the slider, with a vertical axle on which a ball bearing is arranged.

Abstract: A volume flow or pressure regulating device is described which is especially suitable for air conditioning or air heating systems. The device transmits a torque moment function onto the flap control shaft in response to the flap angle. The device includes primarily a shaft (2) which is rotatably supported and extends through a conduit (3) in which the flap is mounted on the shaft which cooperates with a curved cam disk (10). One end of a tension cable (9) is secured to a circumferential point of the cam disk and the other end of the tension cable (9) is secured to the free end of a bending spring 6, the opposite end of which is secured to a fixed point. An adjustable tensioning member (7) defines, in accordance with its position relative to the length of the bending spring (6) the effective or bendable length of the bending spring (6).

Abstract: Heat is recovered by combining a heat transfer system including heat exchangers interconnected in a circulatory system, with a heat pump system. The heat pump system is preferably operated in accordance with the Lorenz-Principle. It is not necessary to divide the heat carrier circuit of the heat pump into two or three separate circulatory circuits. The heat carrier circuit of the heat pump can thus continue to operate unchanged even if the heat pump is switched off. For this purpose the warm heat carrier coming from a discharge fluid cooler, is heated further in a condenser of the heat pump and the cold heat carrier coming from a preheater or cooler group, is cooled further in an evaporator of the heat pump.

Abstract: The invention relates to an improved shuttering device for preventing back-flow in air conduits or the like. The device includes an attachment section and a frame section, the latter being provided with a series of elastic lamellae shiftable between blocking and unblocking positions within the frame, the frame having in addition guide plates extending axially of the conduit to prevent transverse currents.

Abstract: There is disclosed a dewatering roller assembly for Foulard fabrics or the like characterized in that the two rollers through which the fabric strip is passed are caused to bend or deform about mutually corresponding bending lines so that a uniform gap or a predictably variable gap between the rollers is achieved.

Abstract: A chain for a tentering frame includes links which carry so-called tentering hooks and needles for holding a fabric web to a movable conveyor forming the tentering frame. Each link (9) carries an intermediate support member (7) which holds at its free end a journal pin (3) below the margin of a fabric web (1). The journal pin (3) supports an arched bail (2) in a tiltable manner for movement between a working position and a rest position. The bail carries at its upper free end a further journal pin (12) which supports a tentering hook (10) in a tiltable manner. The first journal pin (3) further supports a needle bar (13) which is tiltable with its needles into a fabric penetrating position or into an inoperative position. The needle bar (13) preferably has a flat surface which cooperates with the tentering hooks (10) as a counter-holder when the needles are in a rest position.

By the application of a heated gaseous medium under pressure, the tubular conformation is transported in alternate directions on the tubular carrier.

Abstract: An apparatus for the heat treatment of a material passing through a plurality of treatment zones using a heated gaseous treatment medium conducted in a substantially closed circuit through these zones. A heat exchanger is associated with each treatment zone. The heat exchanger defines, in an operative relation with the respective treatment zone a medium discharge path and a medium replacement path which paths are arranged in a heat exchange relationship. The fractional portion of a treatment medium discharged from each treatment zone transfers its heat and energy to the fresh replacement medium. A throttle or flow control in the medium replacement path for each treatment zone permits individualized control of draft and medium turnover according to the different conditions prevailing in each zone. A filter is also provided to prevent impurities in the medium discharge flow path from entering the heat exchanger.

Abstract: The present linear air outlet comprises a tubular member provided with an air outlet channel formed by two side walls arranged in parallel to each other and reaching into the tubular member. One side wall is perforated. A closure member is movable up and down, for example manually, in the air outlet channel. The closure member has slanted wall surfaces facing alternately into opposite directions inside the air outlet channel so that the slanting surfaces face the respective perforated side wall. Thus, the closure member performs two functions. It opens or closes the perforations in the side walls and with its slanted surfaces it directs the air in a desired direction.

Abstract: A chain guide for a stenter comprises head pieces and end pieces, each carrying a respective return wheel for the associated chain, each head piece being pivotally connected to an associated guide rail so that it can be swung out about a vertical axis and each end piece being displaceable outwardly while remaining parallel to the guide rails. The arrangement allows vertical chain reversal while still allowing clips to be carried by the chain and to engage and disengage a web satisfactorily.
