The dye mixtures yield on hydroxy- and/or carboxamido-containing fiber materials, such as cellulose fibers, in particular cotton, or on, for example, wool and synthetic polyamide fibers, deep black dyeings.

Abstract: An extruder forms shaped bodies from plastics-filler mixtures having a filler content of more than 50% by volume. The extruder comprises a product feed device, an outer mouthpiece and two barrels arranged coaxially between the product feed device and the outer mouthpiece. The first barrel (input cone) having an inside wall provided with grooves essentially parallel to the longitudinal extent of the barrel is connected with the product feed device. The second barrel (output zone) is connected with the outer mouthpiece. A screw arranged in the first barrel conveys material into the second barrel. Separate tempering arrangements for the first barrel, for the second barrel and for the mouthpiece control the desired operation temperatures in the extruder. Preferably, the extruder additionally includes a mandrel connected with the screw and arranged in the second barrel.

Abstract: Stable polymer dispersions with polymer particle sizes of 0.1 to 10 .mu.m are prepared by dissolving a water-in-oil emulsion, comprising a polymer dissolved in an organic solvent which is immiscible with water (organic phase) and an aqueous phase, wherein the viscosity of the organic phase is 1.0 to 20,000 mPas (measured at 25.degree. C.), the surface tension between organic and aqueous phase is 0.01 to 30 mN/m, the particle size of the water emulsified in the organic phase is 0.2 to 50 .mu.m and the ratio by volume of organic phase to aqueous phase is in the range 80:20 to 20:80, subjecting this emulsion to a shear process at a shear power of 1.times.10.sup.3 to 1.times.10.sup.8 Watts per cm.sup.3, wherein the water-in-oil emulsion is converted into an oil-in-water emulsion.

Abstract: An ink jet system comprising a recording material and at least one colored ink to be applied to the recording material by means of an ink jet nozzle, characterized in that at least either the material or the at least one colored ink contains at least one water-soluble compound of general formulae (I) or (II): ##STR1## wherein R.sub.1, Z.sub.1, Z.sub.2, Z.sub.3, Z.sub.4, Z.sub.5, Z.sub.6, X.sub.1, X.sub.2, X.sub.3, X.sub.4, X.sub.5, R.sub.2, R.sub.3, R.sub.4 and n have the meanings given in the description, are distinguished by improved protection of the ink jet dyes from light.

Abstract: The plasticity of ceramic compositions and dispersions can be improved by addition of at least one polymer (I) with recurring succinyl units. This effect can be reversed by addition of a setting accelerator (II); preferred setting accelerators are polymers (II) of the polyalkylenepolyamine type.

Abstract: An apparatus and method are described for delivering fruit trays such as molded pulp apple trays from a nested stack to a conveyer. A carriage arrangement which is moveable relative to the tray stack and the conveyer is provided with support arms and grasping arms. As the apparatus moves through a tray-delivering cycle, the tray stack is supported by the support arms and the lowermost tray is grasped from the stack by the grasping arms and released onto the conveyer.

Abstract: Free-flowing polytetrafluoroethylene molding powders are obtained if a finely divided non free-flowing powder of an optionally modified polytetrafluoroethylene is agglomerated in an aqueous medium which contains a trialkylamine oxide and the agglomerates are dried.

Abstract: Polymeric coating systems comprising an oxidized polyarylene sulfide, especially polyarylene sulfone or partially oxidized polyarylene sulfide, are of improved abrasion resistance. The coating systems preferably comprise a polymer, a binder resin and oxidized polyarylene sulfide, and are suspended in a liquid vehicle. The coating systems are used for coating the surface of metallic and nonmetallic substrates.

Abstract: A speaker controller for a fire alarm system including a control panel and at least one speaker to broadcast tone and/or voice signals during a fire alarm condition acts between the control panel and the at least one speaker. The speaker controller includes a signal recognizer to monitor tone and/or voice signals conveyed to the speaker. Manually actuable switching means are provided to disable the speaker. A reset circuit is responsive to the signal recognizer and resets the switching means thereby to enable the speaker upon a predetermined signal condition being detected by the signal recognizer.

Abstract: A colour photographic material which contains an OH-functional polylactone in at least one layer is distinguished by improved maximum densities.

Abstract: This invention relates to a method for producing aluminum phosphinates of the formula [R.sub.1 R.sub.2 P(O)O.sup.- ].sub.3 Al.sup.3 +, where R.sub.1 and R.sub.2 are the same or different and represent a C.sub.1-8 alkyl group or a phenyl group. The process involves reaction of the corresponding alkali metal phosphinate with aluminum sulfate. The aluminum phosphinate salts are useful as a flame retardant for plastics.

Abstract: A microfilm cartridge assembly includes a hollow housing in which a reel is mounted. A bearing surface results from the end of a boss on the reel making contact with a circular seat around a boss on one of the walls of the housing. The housing boss is inserted into the reel boss to provide a second bearing surface between the telescopically arranged bosses.

Abstract: A light-tight packaging entity includes rigid side covers (4) and a flexible light-tight covering film (3), which envelops the curved surface of a file roll (1) and is shrunk onto outer edges (5) of the side covers (4) to keep incident light away. This packaging entity makes it possible to achieve reliable protection from light with a packaging entity of small size, ensures unimpeded rewinding of the film, and enables the light-sensitive material to be handled in daylight. The present packaging entity is space-saving, capable of being rewound, leaves no packaging residues in the processing device after opening and unrolling have taken place, and in addition is simple and cost-effective.

Abstract: A shooting aid for basketball players designed to keep the elbow of the shooting arm in towards the center line of the body during shooting. The shooting aid comprises a sleeve adapted to fit around the shooting arm of the basketball player; a clip adapted to be secured to clothing worn by the basketball player; and an elastic cord with two ends having one end attached to the sleeve and the other end attached to the clip, wherein the cord is of sufficient length to restrain the position of the player's shooting arm when the player shoots a basketball. In another embodiment, a belt adapted to be worn by the player can be used instead of the clip.

Abstract: A method of calculating beam landing errors in an electronic display device having color phosphor elements and electron guns to generate electron beams to impinge on corresponding phosphor elements require a magnetic field to be generated to deflect an electron beam relative to the corresponding phosphor element on which the electron beam is to impinge. The intensity of light emitted by the phosphor elements in the measurement area is measured as the electron beam impinges thereon. The polarity of the magnetic field is reversed and the above step is repeated. Thereafter, the magnitude of the magnetic field is changed and the above two steps are repeated thereby to measure at least two different light intensities resulting from electron beam influenced by each polarity magnetic field. The at least two different light intensities resulting from electron beams influenced by each polarity magnetic field are then approximated with straight lines and an intersection point of the straight lines is determined.
