摘要:
The warp knitting machine for jacquard-patterned pile-knit fabrics includes pile yarn carriers which are individually movable, according to a selected pattern, in the place of each needle to form a shed of the selected pattern forming and the non-selected pile yarns whereby the tip of the shed is at the knock-over point of the needle. A guide reed is movably arranged between the pile yarn carriers and a pile sinker and includes a laying edge which crosses the pattern-forming pile yarn of the shed. The guide reed performs lateral and sinking movement to overlay the selected pile yarn.
摘要:
A tool-changing mechanism for machine tools of the kind in which tools can be inserted into a spindle. A tool magazine receives several tools and a double-ended tool-changing arm is provided on each of its two ends with gripping mechanisms. The tool-changing arm is rotatable about an axis of rotation which is parallel to the spindle axis and the tool-changing arm can be moved along the direction of its axis of rotation. The tool-changing arm can also be pivoted, between a working position and a rest position, about a pivot axis which is parallel to its axis of rotation.

Water-soluble surface-active esters of di- to hexa-hydric aliphatic alcohols which have been reacted with propylene oxide and/or ethylene oxide and thereafter with at least two moles of a carboxylic acid of up to 22 carbon atoms are useful for dyestuff preparations. These preparations have good flow properties even with high dyestuff concentrations and low contents of said esters and optionally other surfactants and can be used in dyeing and printing procedures, especially in printing pastes for printing transfer sheets.
