Abstract: The invention relates to pasty pigment formulations of pigments of the arylpararosanilinesulfonic acid series, which are free of aromatics-containing mineral oils and are suitable for preparing printing inks, in particular letterpress and offset printing inks. The pigment formulations are obtainable by flushing aqueous presscakes of the pigments by means of the solution of a flushing resin in aromatics-free mineral oil and preparing the flushed paste obtained with an oil- or fatty-acid modified alkyd resin.

Abstract: A card clothing for a stationary or movable carding segments of a carding machine includes at least two rows of groups of tips. The rows are located one after another in the direction of carding and each row extends transversally of the direction of carding. Each group has from two to six tips positioned one after another. The groups of the tips in the first row are laterally spaced from each other a distance equal to at least three widths of each group. The groups of tips arranged in the following row are laterally offset relative to the groups of the previous row, as seen in the direction of carding, a distance equal to at least the width of one group.

Abstract: The invention relates to readily dispersible strong pigment formulations containing arylpararosanilinesulfonic acid pigments of the formula ##STR1## and a polyester resin which has been water-solubilized by neutralizing the carboxyl groups with nitrogen bases.The pigment formulations are distinguished by being very readily dispersible in the various printing ink binders and by having a high tinctorial strength.

Abstract: Aryl-pararosaniline sulfonic acid pigments can be transformed into a pigment preparation having high tinctorial strength and being easily dispersible by dissolving them in aqueous alkali, adding a water-soluble synthetic resin (being a reaction product or mixture of (I) maleic anhydride addition product of an unsaturated fatty acid or fatty acid polyol ester, said addition product being partially esterified with a polyol, and (II) a low-molecular curable and partially etherified aminoplast and optionally an anionic or nonionic surfactant and precipitating the preparation with a mineral acid. These preparations are especially useful for pigmenting printing inks, carbon paper, duplicating papers and typewriter ribbons.

Abstract: An electronic chess clock includes a generally rectangular casing atop which an elongate switching lever is mounted for pivotal movement about the center of the lever. A pair of electrochemical clockworks are contained in the casing for measuring and displaying time periods representing deliberation time of the chess players. A selected one of the two clockworks is actuated when the switching lever is pivoted downwardly at one end to actuate a microswitch associated with the selected clockwork. A common quartz-controlled time module provides time pulses to the selected one of the clockworks to insure that both of the clockworks operate at an equal rate. A manually actuable change-over switch coupled to the time module operates to allow the frequency of the time pulses to be selected so that the hand of the clockworks can indicate elapsed time on an expanded scale for greater accuracy in "short time" chess matches.

Abstract: 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.

Abstract: In knitted goods, particularly pile-knit goods, with pile yarn tied into the loops and with weft elements extending at least over two-needle spacings, the pile-forming pile yarns are tied together only in every second course. This may be implemented by tying-in the pile yarns as loop jointly with the meshing yarn while weft yarns and dead piles are preferably tied as weft into the in-between courses. When tying the patterning piles as weft into every second course, dead pile and weft are also ties into these courses, while the in-between course will preferably consist only of the meshing warp yarn.

The liquid and solid dyestuff preparations containing these oxalkylates are stable to storing even with high dyestuff concentrations, easily redispersible while developing little foam and easily biodegradable.

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.

Abstract: 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.

Abstract: A warp knitting machine has a row of needles, a row of warp thread guides for feeding to the needles warp threads which form the chain stitches of a ground fabric and a row of weft thread guides for feeding to the needles weft threads which form the inlay of the ground fabric. At least one row of pile thread guides is used to feed a respective pile thread to each needle. A row of pile-thread reserve-forming supports is provided, each support being individually shiftable, by a jacquard mechanism, from a reserve-forming position to a reserve-releasing position. The reserve-forming support, when in the reserve-forming position, forms a reserve length in a respective pile thread, by increasing the length of the path which the pile thread takes to a respective needle. Each and every pile thread is provided with such a reserve length in each and every course of the fabric. Each needle is provided with a clamp which clamps the pile thread to the needle.

Abstract: A double, jacquard-patterned piled fabric is produced on a modified warp-knitting machine having two needle-rows whose needles form needle-pairs. Each needle-pair receives a respective set of pile threads, differing ones of which are at different points in a pattern to become patterning pile threads visible in the fabric's pile pattern. When a given pile thread is to be non-patterning, it is tied into one of the two ground fabrics in the form of a walewise-running unlooped thread, and is not knitted into the ground fabric in the form of either half or full loops, in order to greatly reduce the rate of consumption of non-patterning pile thread. When a pile thread is to become a patterning pile thread, it is displaced into the zone intermediate the two needle rows and incorporated into alternate ones of the two ground fabrics in the form of half-loops.
