摘要:
The present invention relates to a gear mechanism for the drive assembly of a heald shaft (1), wherein the gear mechanism (6, 6a, 6b, 6c) comprises an input shaft (7, 7b, 7c) and an output shaft (5, 5b, 5c). The gear mechanism (6, 6a, 6b, 6c) generates a differential angle of rotation between the input shaft (7, 7b, 7c) and the output shaft (5, 5b, 5c) that is superimposed on the angle of rotation and, in dependence on the angle of rotation, is subjected to an oscillating change. This oscillating change can differ from a harmonic oscillation as a result of the non-circular design of the planet gears (11a, 12a, 13a) of the gear mechanism (6, 6b, 6c), thereby making it possible to realize almost any optional movements for the heald shaft (1), with low strain on the gears and the bearings. The invention furthermore discloses a simple production method and a compact design.
摘要:
A textile sheet made with improved surface effects and from yarns with typical unfavorable characteristics (firm round yarn cross-section, low hairiness), of the rotor OE (open end), MJS (murate-jet), sirospun or friction yarns, which, as the result of a multiple needle process with the effect of already known felting needles, shows improved properties including a higher volume, a softer touch, is warmer, and has increased tenacity and hairiness than before the finishing process.

Cadmium (Cd.sup.++) ions are separated from an effluent containing complexing agent such as nitrilotriacetic acid, ethylenediamine tetraacetic acid and/or diethylenetriamine pentaacetic acid, or their anionic salts by using an HS-containing triazine compound and Fe.sup.+++ ions in a quantity at least equal to the amount of complexing agent.
摘要:
A stamping device, which in particular is arranged for stamping unfired ceramic substrates, has a die holder device with a plurality of dies, which for activation can be locked to the die holder device and then jointly with it execute an axial stamping motion. A coupling device which is remote-actuated is used for the locking. For the remote transmission of the actuation motion, a flexible mechanical connecting arrangement is used, such as preferably a cable.

A method is provided for the determination and elimination of visible defects in textile webs, wherein the web is moved in the longitudinal direction over a defect seeking and registering area, and the surface position of visible defective areas, such as material deficiencies or excesses with regard to fiber components of the web are located in their surface dimension by known means during the movement of the web, as compared to the adjacent areas of the web. The defective areas are registered as a deviation from the reference condition, and the web is subsequently stopped with the defect in a position above a needle base into which felting needles are sunk. In the case of material deficiencies, the defective areas are supplied with donor material from a reserve, to control their defect by pushing the donor material into the web and stitching it to the defective area with at least two felting needles at 50 to 500 perforations per cm.sup.2, In the case of material excesses, the fiber components of the excesses are pushed into the web by notches or hooks of at least two felting needles at 50 to 200 perforations per cm.sup.2. Following the last perforation in the defective area, the defective web is freed for further movement at a pace relatively faster than the movement of non-aligned donor material, and is separated from the reserve by tearing or cutting.

A method for reprocessing used lubricating oils is disclosed wherein the oil is dried, treated with finely dispersed sodium metal at elevated temperature, the remaining free or organically bound metal is decomposed by means of an active hydrogen containing compounds, followed by distillation of the oil for recovery.
摘要:
Caking of industrial alkali metal chlorides and mixtures containing them in storage is prevented and a flowable product is obtained by adding a hydrophilic and/or a hydrophobic material, in combination with a complex iron cyanide, on a hydroxyl group containing carrier to produce a permanent moisture content of at least 0.01 weight percent of water on the salt.
摘要:
Discrete particles consisting of thermoplastic synthetic resin, which are adapted to melt and to produce a high frequency weld joint under the action of a high frequency field and to resist the action of detergents and dry cleaning agents are arranged on at least one boundary surface of a support structure which is permeable to gas, vapor and liquid, and which is preferably constituted by a continuous web to which the particles are preferably fixed by the application of pressure and/or heat. An additional layer, preferably also consisting of a continuous web, is then applied to the one boundary surface of the support structure and the thus-formed composite structure is subjected to the action of a high frequency field to provide a welded joint connecting the additional layer to the support structure.
