Patent EP-0244706-A2 (EP)
Inventor: HOFSTETTER HANS
IPC: D06P3/28
Filed: 1987-04-24
Abstract: In the dyeing of polyamide-cotton mixtures with azoic dyes only it is important to have dye-forming components which exhaust conjointly on at least one of the two fibres. Another prerequisite is that the coupling and diazo components in question remain stable side by side in the same exhaust bath under the conditions of the first impregnation without precipitation of azo dyes already formed in this liquor as a result of coupling or any other separation, which would have an adverse effect on the fastness of the dyeings to be produced only on the fibre. The lately available liquid preparations of specially dispersed aromatic amines, then, are diazo component precursors which meet the requirements mentioned, so that the two different constituent fibres of the blend can be coloured, admittedly in succession, but with one and the same class of dye. In addition, owing to the separate dyeing of the two fibre portions, it is possible, by varying the amines used as diazo components, to obtain bicolour effects.

Abstract: The gradation correction of input video signals (11R, 11G, 11B) is conducted in the gradation correctors (14R, 14G, 14B) based on the lookup table data (LUTR, LUTG, LUTB). The cumulative histograms of the input video signals (11R, 11G, 11B) are generated in the cumulative histogram generators (32R, 32G, 32B) to set highlight points and shadow points. Based on the highlight and shadow points, the standard lookup table data stored in the standard lookup table storage (36) is converted into lookup table data (LUTR, LUTG, LUTB) associated with the input video signals (11R, 11G, 11B) and outputted to the gradation correctors (14R, 14G, 14B). According to this method, an appropriate gradation correction can be achieved depending on the input video signals (11R, 11G, 11B). The standard lookup table storage (36) need only be loaded with the standard lookup table data, namely, a great volume of lookup table data need not be stored.

Title: Polarized magnetic drive for electromagnetic switching device
Inventor: DIETRICH BERNHARD
IPC: H01H51/22
Filed: 1987-09-15
Abstract: The magnetic drive of an electromagnetic contactor com­prises two spaced coils (10, 11) having a coaxial bore in which an armature (14) is mounted for reciprocal movement be­tween two end positions. A control slider (21) is disposed be­tween the coils (10, 11) with its two sides forming stops for the armature (14). When the armature (14) is changed over from one to the other end position, the slider is also changed over and limits in the mid-position the return movement of the ar­mature (14) from the respective end position. In a contactor designed for tri-stable operation, undesired movement of the armature beyond the mid-position is avoided, which could otherwise lead to an inadvertent change-over of the armature (14) to the other end position. If the contactor is designed for monostable mid-position operation, oscillation of the ar­mature (14) about the mid-position is prevented, so that this mid-position is stabilized.

Abstract: Explosion and flame-proof electrical equipment, that is to say equipment with a housing of the "pressure-proof encapsulation" protection type, must satisfy specific regulations relating to connection to electrical conductors. The regulation applying to plug-in devices is that these must be interlocked such that they can be withdrawn only when they are not live. There are specific conductor inlets for such equipment which already have official approval. However, with a large number of conductors or conductor wires, the individual connection of the conductor wires to the equipment inside the housing is tiresome. The invention produces a plug-connector intermediate part which is attached to the housing and cannot be released until the approved conductor inlet has been released. The intermediate part permits quick connection of electrical equipment of the said type to an electrical conductor. When the conductor inlet is released, the housing is regarded as being open so that the said instructions for plug-in devices do not apply. A normal plug-connector is thus fitted inside the housing, which allows a plurality of types of conductor to be connected quickly.

Abstract: A device for acting upon a stack of a laminar objects or a row of laminar object elements with a fluid stream, in particular a gas stream, such as can be used for heat treatment of laminar objects with a large width extent of the stack in relation to the height of the individual object layers, or of a row of object elements which are high in relation to their thickness, has a radial fan, arranged above the object stack or the object row, with a housing blowing out on two sides, which housing supplies blow-out channels, which are arranged in each case at the sides of the object stack and staggered in relation to one another, or flow channels which are situated above and below the object row and equipped with nozzles arranged in a staggered manner. The volume flow supplied from the radial fan is thus blown alternately against the corresponding part of the side surface of the object stack and thus also through the intermediate spaces, between the individual layers of the object stack, contained in this side surface, or, in the case of the object row, alternately from above and below into the gaps between the object elements, as a result of which uniform action upon the object stack from both sides and in the case of the object row from above and below is achieved, which would otherwise only be possible by reversing the flow. <IMAGE>
