Abstract: Three-dimensional knitted catalyst gauzes made from noble metals have recently come into use for ammonia oxidation and other gaseous reactions. Particularly high yields accompanied by a stable course of the reaction and an extended service life of the catalyst gauze are achieved if the catalyst gauzes are knitted in two or more layers and the layers are connected together by pile threads. Important features are the largest possible number of pile threads per unit area and the alignment thereof as parallel as possible to the direction of flow of the reaction gases.

Abstract: In order to improve the handling and filtering characteristics of a multilayered, textile, gas-permeable filter material against toxic chemical substances and, in particular, filter and protective materials for the production of sheet-like filters and protective suits for the civil and military fields, it is suggested that this filter material have a first layer as textile support layer which is bonded to a second layer present in the form of an areal adhesive layer. In addition, the filter material has a third layer applied to the second layer and areally bonded thereto, this third layer comprising a textile sheet-like layer containing activated carbon fibers.

Abstract: A blank material for manufacturing fiber-reinforced coatings or metal components comprising fibers made of a high-strength material and metals or metal alloys, and a process for manufacturing the blank, and for manufacturing coatings and components made therefrom. The fibers are aligned in the blank in parallel to its axis, and metal wire meshes are knitted around them, with the fibers embedded at a distance from one another. By means of high-temperature isostatic pressing, metal components can be made, through which the reinforcing fibers extend at a uniform distance.

Abstract: A method of knitting a multi-dimensional fabric for use in upholstery is accomplished by simultaneously knitting rib and jersey wales. The resultant fabric creates a layered or convex pocket appearance similar to that of pleated fabric formed by sewing. The method uses movement of the rib forming carriage to form pockets that are connected by the jersey stitches on the rear face and rib stitches on the face of the fabric.

Abstract: In the process for the fully-fashioned knitting of intarsia jacquard fabric on a two-bed flat knitting machine, intarsia yarns floating on the back of the fully-fashioned fabric are avoided even in intarsia regions of changing width by effecting a yarn-guide adjustment at points of change of direction of the intarsia regions, and the resulting floating intarsia yarns are subsequently bound into the fabric.

Abstract: Wires of platinum containing 4 to 12% rhodium or 4 to 12% of palladium and rhodium (4 to 12% being in reference to the sum of palladium and rhodium and not the percent values for each individually) and wires of palladium containing 2 to 15% nickel or 2 to 15% copper or 2 to 15% of nickel and copper (2 to 15% being in reference to the sum of nickel and copper) and having a diameter of 50 to 120 .mu.m, a tensile strength of 900 to 1050 N/mm.sup.2 and an elastic limit of 0.5 to 3% are used for the knitting of round nets for use as catalysts in the oxidation of ammonia and as recovery nets for platinum metals. A flat knitting machine with a gauge of 3.63 to 1.81 mm is also used whereby the loop length is 2 to 6 mm and wherein the loop or width gauge corresponds with the knitting machine gauge so as to provide a loop width of 1.81 to 3.63 mm.

Abstract: In a knitting take-off device provided with gripping elements (14) movable through the comb gap of a flat bed knitting machine, the plane of the gripping elements (14) is directed perpendicular to the hooking planes of the knitting needles (13) mounted in the needle beds. As a result, the dimensions of the gripping elements are no longer limited by the width of the comb gap, and the gripping elements (14) can be coupled to additional elements, such as a cover stop rod (16). By means of the cover stop rod (16), the opening (14.2) of the gripping element (14) can be closed and a thread take-up space (20), closable by the head (14.1) of the gripping element (14), can be formed.

Abstract: In a flat knitting machine with adjustable sinkers (33), these sinkers are in each case arranged between a needle (43) and a fixed loop-forming web (31) of a needle bed (42) and designed in such a way that they can cooperate with the loop-forming webs (31) forming a draw edge when newly-formed loops are knocked over.

Abstract: In a method for the production of intarsia knitted pieces on a flat-bed knitting machine, at least some of the yarn guides associated with each one of the intarsia areas and the respective needle bed are moved in a direction relative to each other when one of the needle beds is traversed in both lift directions by a carriage provided with one or a plurality of cams in the border area between two areas of intarsia, and the yarn guides are being coupled with the movement of the carriage in each intarsia area. At the end of a movement segment which extends at most across a number of intarsia areas corresponding to the number of cams, the carriage is reversed in its lift direction and returned, together with the yarn guide last used as well as with the yarn guide to be used for the following intarsia area, to the intarsia area last produced, without making a needle selection.

Abstract: In a flat knitting machine, the segments (10.1,11.1), of any desired width, which make up the needle beds (10, 11), are designed to be used with needles of different gauges, i.e. are formed with a different needle separation, so that needles of different gauges are used in adjacent needle bed segments (10.1, 11.1). On a flat knitting machine comprising a carriage (14/15) which can be traversed across the needle beds (10, 11) and has several cam systems (14.1-14.4; 15.1-15.4), the individual cam systems can be allocated to needles of different gauges, while at least one of the several cam systems may differ from the others by a different form of loop-transfer control curve.

Abstract: A device for the display and editing of knitting patterns to be produced by means of a flat-bed knitting machine has an image memory containing the knitting pattern loop by loop in an arrangement by lines and columns, which is on its input side connected with a horizontal and a vertical address counter and on its output side with a monitor, furthermore a CPU for the programmed control of the image memory and of the monitor, and a data entry device. In order to obtain in such a device a change in the knitting pattern, especially the stretching of loops, in a simpler and quicker way and with a lesser need for memory locations, a device is provided for the pre-determined change by line or point of at least parts of the data content read from the image memory, in which image memory a memory location each is associated with a corresponding loop of the knitting pattern, as well as for displaying of both the changed part of the data content and the unchanged part of the data content on the monitor.

Abstract: The flat knitting machine has the thread-leading ducts (15) which envelop the threads conveyed to the thread guides (10) and which with their thread exit point on the side nearest the thread guide are adaptable to the changing distance between thread guides (10) and needle bed ends.

Abstract: The yarn feeder slide proposed for intarsia knitting on a flat knitting machine and provided with a braking device has brake shoes (22,23) projecting sideways on pivoted levers (16,31) and which extend into a special longitudinal slot of the associated yarn feeder rail and can be jammed therein. Two control regions (19,38) for the braking device or for a moveable yarn feeder arm are provided and are spaced from one another in the direction of displacement of the yarn feeder slide (10) so that the yarn feeder driving member located on the cam carriage of the flat knitting machine can be selectively lowered into both control regions (19,38) of the yarn feeder slide.

Abstract: A flat-bed knitting machine is described, the needle bed apparatus of which has a front and back needle bed, each continuous and extending over a substantial portion of the machine length, and the carriage apparatus of which, having a stop-free cam system, is movable back and forth on or above the needle bed apparatus by means of a drive apparatus and is triggered by a program for various knitting patterns. The intent is with this kind of flat-bed knitting machine to enable more-productive knitting of two or more articles on the needle bed apparatus in one operation, by exploiting the needle bed space, and at the same time to use it for knitting only a single article on the needle bed apparatus.

Abstract: A flat-bed knitting machine has been described which is provided with needle sinkers arranged in a knitting cam system of a cam box carriage featuring several cams adjustable by means of stepping motors and having an electronic control unit, which features a storage device for controlling the stepping motors. In order to make the knitting density variable not only in the longitudinal direction, i.e. uniformly as a whole, row by row, but also in the transverse direction across the knitting with knitting machines of this type, the stepping motors are controlled by the storage device, one motor of which, in each case, is associated with a pair of needle sinkers consisting of preceding and trailing needle sinkers during the stroke of the cam box carriage and in synchronism with the individual needles.

Abstract: In a device for setting the adjustable traverse of a plurality of yarn feeders of a flat knitting machine, the yarn feeder limit stops (19) associated with each yarn feeder slide (15) are preferably formed as signal generators and are arranged to be longitudinally slidable on separate guide tracks of the yarn feeder rails (10-13) so that the yarn feeder slides (15) can overlap the associated yarn feeder limit stops (19). The yarn feeder limit stops (19) effect a switching procedure for the coupling devices (28) located on the cam carriage (14) which effect the movement of the yarn feeder slides (15).

Abstract: This describes a fabric take-down device (11) for flat knitting machines which is provided with a driving motor (12) and an associated adjusting device (13) to set the torque of the driving motor (12) which determines the take-down pull through the motor current.In order to provide in a fabric take-down arrangement (11) of this character for a substantial starting and controlled pull, and in particular to cater for a finely-sensitized regulation even in the area of small torque values, provision is made for the adjusting device (11) to be constituted by a motor-current regulating system (26) which is provided with inputs (27, 28, 33, 34, 39) for setting the target figures and for at least one actual value taken from the driving motor (12), and the regulating system (26) further has an input (32) for an augmenting shift pulse for a short-term increase in the torque of the driving motor (12) where there is a small target tongue (FIG. 1).
