Abstract: The present invention relates to a process for coloring cellulosic substrates, which comprises substrates to be colored, or precursors thereof, being contacted with at least one treated pigment in particulate form that is at least partially enveloped by at least one cationic copolymer.

Abstract: The invention concerns a new therapeutic agent for use in treating psoriasis, new compositions of the therapeutic agent for topical administration and a new method of treating psoriasis.

Abstract: Novel dye mixtures which contain dyes of the general formulae I ##STR1## and II ##STR2## in the form of the alkali metal and ammonium salts, where m and n are each 0 to 4, p and q are each 1 or 2, r is 0 or 1, m+n is 2, 3 or 4, B.sup.1 and B.sup.2 are each hydrogen or chlorine, or B.sup.1 and B.sup.2 together form part of a fused benzene ring which is unsubstituted or substituted by SO.sub.3 H, R.sup.1 and R.sup.2 independently of one another are each hydrogen or unsubstituted or substituted lower alkyl or cyclohexyl, or R.sup.1 and R.sup.2 together with the nitrogen form a saturated heterocyclic structure, and Z is a reactive radical which is usually present in reactive dyes and which is bonded to the diazo or coupling component, are very useful for dyeing paper stocks.

Abstract: A field sensor control mechanism for doors and the like has two or more insulated electrodes mounted at different levels in the leading edge of a door or the like. A first oscillating circuit is connected with one of these electrodes and a second oscillating circuit, separate from the first one and serving as a comparison circuit for the same, is connected to the other electrode. The two circuits have base oscillating frequencies which are either identical or differ only slightly from one another. The circuits are so coupled to one another that the oscillations of the first circuit vary as a function of capacitance changes taking place in the electrodes.

Abstract: A screwdriver or like hand tool has interchangeable tips or bits storable in a groove or recess in a handle, and a foldable auxiliary lever for increased torque which is pivotable into another recess in the handle. The interchangeable tips or bits and the lever are magnetically releasibly retained in their recesses. Bits fit into and are magnetically retained in a socket at the end of a shaft rotatably mounted in the handle. The lever in its inwardly pivoted storage position keys the shaft to the handle. A reversible ratchet is provided. The tool may be a screwdriver or a tool for wrench sockets, screw extractors, or other types of bits or tips.

Abstract: A two-step method for washing textiles which comprises washing said textiles in a first step with an aqueous bath containing both a cationic surface-active agent and a non-ionogenic surface-active agent, and then washing said textiles in a second step with an aqueous bath containing conventional builders and an anionic surface-active agent, a non-ionogenic surface-active agent, or both.

Abstract: An electrically heated parting tool for removing windshields and other uses has a holder in the form of a long slender housing mounting a blade-like parting element at one end. The parting element is constructed of thin flat sheet metal and has a generally U-shape including a pair of thin flat leg portions disposed in coplanar relation and joined by a thin flat connecting portion defining a tip end. The free ends of the element leg portions are secured to a high temperature resistant ceramic-like support member recessed into one side of the holder. The parting element extends longitudinally from the holder and has a right angle bend between the holder and tip end whereby the tip end extends laterally of and toward the opposite side of the holder in spaced relation to the holder end. The holder includes a housing at the opposite end in which is located a step-down transformer connected to the leg portions of the parting element by leads extending through the holder.
