摘要:
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.

In the flat knitting machine with a needle selection device, the needles (12) are selected at double selection points and the non-selected needles (12) are locked by means of a locking jack (25) and the control butt (22) of their needle jack (19) is removed from the cam tracks. Force is transmitted to the needle (12) at a special coupling position (23/24) from the control butt (22) of the needle jack (19) articulated to the needle (12), and to increase the control possibilities without provision of additional cam tracks, presser cam elements (57-59), which act on the depressor butts (26) of the locking jacks (25) can be displaced in the plane of the cams. (FIG. 1).
摘要:
A flat knitting machine has at least one needle bed, a carriage which slides along the needle bed which has at least one cam with needle section means and stitch cams, a sinking element which cooperates with the stitch cams and is arranged movably on the stitch cams, the sinking element being controllable independently from the stitch cams and together with the stitch cams forms sinking surfaces of different size and/or form depending on its position.

Subject matter of the invention are protein-containing interference-reducing agents for immunoassays consisting of protein aggregates that are acylated with --CO--R groups, wherein R is a branched or non-branched C1-C4 alkyl residue which can be substituted with hydroxy, carboxy, SO.sub.3 H or PO.sub.3 H.sub.2 groups. These interference-reducing substances can be used together with a buffer as an interference-reducing agent or together with an immunological binding partner as a binding reagent to reduce non-specific interactions in immunoassays. Another subject matter of the invention is an immunological testing method wherein said interference-reducing substances are used.
摘要:
The draw-off mechanism for a flat bar knitting machine having needle beds includes a pair of driven feed rollers arranged axially parallel to each other and located adjacent to the needle beds under a gap between the needle beds; a pair of pivoting levers, each pivoting lever being two-armed and having a feed roller mounted at one end thereof and an adjustable stop device for setting a minimum spacing between the feed rollers located at another end of each pivoting lever remote from the feed rollers; and a device for adjusting an initial tension on at least one of the pivoting levers to urge the pivoting levers closer together, so that the driven feed rollers can cooperate with each other and act on a workpiece running between them.
摘要:
The threading and yarn-changing device allows yarn guides each to be equipped automatically and selectively with one of a plurality of yarns (14, 15). It possesses a nozzle head (11) and a yarn-proportioning device (12) with guide parts (30.1, 30.2) for each of the yarns (14, 15) and an additional yarn-clamping and cutting-off device (13) and can be arranged in a stationary or movable manner on a knitting machine.
摘要:
A knitted article is produced on a flat knitting machine with a carriage and at least one cam system, wherein the carriage speed is controlled within a knitting row in dependence on pattern types produced by individual needles or needle groups, as well as on the properties of knitting thread or threads continuously so that the carriage at each location of the knitting row is moved with a maximum possible speed at which it is guaranteed that no knitting thread is torn.
摘要:
In the yarn-delivery device having at least one friction cylinder (11, 12) and at least one pivoting arm (15, 16) for each yarn (20) to be delivered, the pivoting arms having at least one deflecting roller for the yarn are mounted pivotably outside the friction cylinder and are so curved that they are pivotable to behind a friction cylinder (11, 12) and a plurality of pivoting arms (15, 16) for separate yarns (20) can be arranged next to one another. (FIG. 1)
摘要:
The conventional multiple-spindle automatic lathes are expensive on account of their complicated construction, and the production output and production possibilities are limited on account of the restricted number of work spindles utilized. The novel automatic lathe is to offer higher production outputs and more universal manufacturing possibilities with a simpler construction.The basic structure of an automatic lathe with eight tool spindles (10) for the manufacture of workpieces in eight successive machining stations resides in that, additionally to the number of basic tool stations (1 through 8), each basic tool station, except for the first, is once more included as an additional tool station (2 through 8) arranged in the same sequence of machining upstream of the basic tool stations (1 through 8) so that the total number of machining stations amounts to N=2n-1, a loading and unloading station being provided at the tool station (1). Machining of the workpieces takes place so that each workpiece, after each machining in a tool station, is shifted cyclically in a linear fashion relatively to the subsequent station, and, after seven conveying steps and a subsequent return stroke, or a return stroke between two conveying steps, enters into its initial machining station.The multiple-spindle automatic lathe is usable for mass production of workpieces of a great variety of types.
摘要:
By the use of special latch needles (21) whose latch (14) can take up two stable positions lying within the limits of its pivotal movement and out of which it can be moved only against the action of a spring, there is ensured, even in fast running flat knitting machines with a transfer mechanism and with stitch presser and/or stitch hold-down elements, and even during the formation of long, loose stitches and loops, reliable trapping of the yarn and manipulation of the stitches and loops by the knitting elements.
