Abstract:
Knitting machine with a needle bed in which knitting tools having projections are mounted for raising and lowering, with a cam unit which can be transported past the projections and which has at least one lowering cam acting on the projections of the knitting tools which is adjustable with regard to its lowering depth, on which a runner is movably fastened having a plurality of pathways interacting according to pattern with the runner during the carrying of the cam unit past the projections of the knitting tools for the adjustment of the lowering cam to a preselected lowering depth, and with a controller acting before each passage of the cam unit past the feet of the knitting tools for the shifting of the runner to the position required for the interaction with a selected pathway (FIG. 7).
Abstract:
The clamping means, which has a clamping position and an open position for material in thread, ribbon or strip form, has an element which, in accordance with the invention, is resiliently bent double hairpin-wise in a first plane and has two arms of substantially equal length, the end of the first arm being bent double to a U shape in a second plane such that the gap between the two limbs of the U formed by this bend is smaller than the cross section of the portion of the free end of the second arm which cooperates with it, and the ends of the two arms being offset from one another parallel to the second plane such that, in the closed position, the free end of the second arm engages both limbs of the U in the area of the gap.
Abstract:
Knitting machine for performing knits having a beginning and an end, which has at least one needle bed in which knitting needles are mounted for extension and retraction, which has a plurality of thread carriers running successively along an endless path and having at least one thread inserter and one thread gripper, the thread carriers being transportable through a working section and through a return section for the return transport of the threads from the end of the knit to the beginning of the knit for the insertion of threads into select needles, and having furthermore at least one thread clipper for severing the threads after they have been worked by the last active needle each time and after they have been gripped in the corresponding thread gripper, and having a control apparatus suitable for varying the knit width for the opening or closing of the thread grippers for the purpose of the release or of the gripping of the thread ends produced by the clipping device and carried by the thread carriers in their return travel, the associated inserters and thread grippers being spaced from one another in a direction different from the transport direction of the thread carriers at least immediately prior to the insertion of the corresponding threads into the first selected needles, such that the thread portions disposed between them are each caught by the first extended needles in the direction of transport and are brought into the position required for the next-following selected needles (FIG. 2).
Abstract:
An apparatus for feeding yarn, or the like vice yarn guides which travel on an endless O-shaped floating-mounted track to present the yarn, or the like to the instrumentalities of a textile machine.
Abstract:
A composition and a method for coating metallic surfaces with a silane/silanol/siloxane/polysiloxane-containing composition, whereby the composition contains a) at least one compound selected from the silanes, silanols, siloxanes and polysiloxanes, b) at least two compounds selected from titanium-, hafnium-, zirconium-, aluminum- or boron-containing compounds, optionally c) at least one type of cation selected from cations of metals of the 1st to 3rd and 5th to 8th sub-groups including the lanthanides and the 2nd main group of the periodic table of the elements or at least one corresponding compound, d) at least one organic compound selected from monomers, oligomers, polymers, copolymers and block copolymers or e) at least one substance affecting the pH value, water and optionally at least one organic solvent.
Abstract:
A brake device of a vehicle, containing an eddy current disk brake having a rotationally fixed stator and a rotating rotor, wherein the rotor or the stator bears an eddy current path and the stator or the rotor bears a magnetic arrangement, the magnetic field lines of which induce eddy currents in the eddy current path for generating a braking torque upon a relative movement of the rotor with respect to the stator, and a friction disk brake having at least one brake disk and brake pads cooperating with the brake disk for generating a braking friction torque between the brake disk and the brake pads, wherein the rotor of the eddy current disk brake is formed by the brake disk of the friction disk brake.
Abstract:
A process for producing a repair coating on a metallic surface coated with a corrosion protecting coating A applied with a pretreatment composition, an organic composition or a silicon compound containing composition. Corrosion protecting coating A has been at least partially removed in the area Z, and a thin corrosion protecting coating B containing a silicon compound is applied with a solution or dispersion containing a silane, a silanol, a siloxane, a polysiloxane or a mixture thereof on at least a part of the area Z. A further corrosion protecting coating C which is generated with an organic composition like a primer, a wet-primer, an e-coat, a powder coat, a base-coat or a clear-coat or a composition which is the same or another siloxane composition as for the thin film B may also be applied to coating B.
