Abstract: A head part comprising ink ejection channels in the ink printer head is cast into an outer mount with a rubber-elastic casting compound. A silanization layer is situated on the side of the discharge openings of the ink ejection channels. The hydrophobic effect of this silanization layer is intensified by silicone fluid added before the casting of the casting compound, since the silicone fluid diffusing out of the casting compound and later spreads by creeping and forms a layer of silicone fluid on the silanization layer. The layer of silicone fluid is constantly replenished from the inside of the casting compound. The layer of silicone fluid also simultaneously protects the silanization layer against hydrolysis. The instant invention is suitable for all ink printer heads that operate with aqueous ink.

Abstract: Apparatus for broaching a cylindrical surface of a workpiece, in which at ast one broaching tool is mounted on a tool carrier rotatable about its axis and about the axis of the cylindrical surface of the workpiece clamped in a stationary position. The broaching tool is independently rotatable about its own axis, and the rotary motion of the tool is superimposed on the rotation of the carrier and consequently the revolving motion of the broaching tool. Since the workpiece is stationary during broaching, very high cutting speeds can be achieved. The broaching tool can be of small and lightweight construction so that it is especially suitable for an automatic tool change. In a preferred form, a plurality of broaching tools are utilized, the axes of which are spaced outwardly from and circumferentially about the axis of the workpiece.

Abstract: 3-(4-alkylbenzoyl)-acrylic acids corresponding to formula (1) ##STR1## in which R is straight-chain or branched-chain C.sub.8 -C.sub.18 alkyl, or mixtures thereof, are useful as corrosion inhibitors in lubricating oils and lubricating greases based on mineral oils.

Abstract: Alkyl glycosides are used to greatly increase the microbicidal activity of biguanide compounds, such as chlorhexidine salts. The alkyl glycoside/biguanide agents have a particular utility in teeth cleaning preparations due to their improved microbicidal activity against gram-positive bacteria.
