摘要:
The present invention relates to a mixing apparatus at least composed of a screw-based machine S1 and a screw-based machine S2, where S1 has heating equipment, at least in the plasticizing and homogenizing zone, and where the outlet from S2 has been connected to the screw-containing barrel of S1, within the plasticizing or homogenizing zone of S1, a substantive feature of which is that the connection between S1 and S2 is brought about by a connector which has cooling equipment effective as far as the inner wall of the screw-containing barrel of S1, and to a process for preparing thermoplastically processable molding compositions, in particular additive masterbatches, from at least one thermoplastic component C1 and at least one component C2, where the melting point or decomposition temperature TMC2 of C2 is lower, by at least about 50° C., than the temperature THC1, which is the lower limit of the thermoforming range of C1, and where most of C2 is melted only after contact with C1.

Shear forces are used for essentially salt-free coagulation of plastics dispersions or rubber dispersions. For this, method of use is made of an apparatus with at least one shearing module which has a stator and a rotor arranged within the stator, where the surfaces facing toward one another in the stator and in the rotor are in each case smooth, or at least the rotor exhibits a structure formed on its surface and facing from this in the direction of the stator, and between the stator and the rotor there is a gap of predetermined gap width. The process is carried out by passing the dispersion to be coagulated through the gap between stator and rotor and precipitating the dispersion by rotation of the rotor with predetermined shear rate and shear deformation.

A process for the continuous coagulation of aqueous dispersions of graft rubbers suitable for toughening thermoplastics is described. In the process, dispersions are transported through an apparatus having at least one shear element with a slotted stator and a rotating of the rotor within the stator, so that said dispersions are passed radially from the inside to the outside as a result of the rotation of the rotor in the shear element and, during or after passage through the slots of the rotor and stator, are subjected to such strong shearing that they coagulate, resulting in graft rubber coagulums which can be readily worked up even at a solids content of more than 50% by weight of elastomers.

In a radio communication system with at least one radio network control device, at least one base station is connected to at least one user station by a radio communication interface. The base station(s) and the radio network control device are components of a base station subsystem. The radio network control device is connected to an access device for a core network. The radio network control device and the user station(s) have a service specific key that is preferably valid for several user stations, or in other words, the service specific key is not user specific.

This invention provides an apparatus and method for injecting an additive directly into a polymer melt stream. The method comprises supplying a melt flow of a polymeric host material to a die assembly having a thin-plate assembly and injecting at least one additive into at least one predetermined location in a cross-section of the melt flow of the polymeric host material while the melt flow passes through the die assembly. The method achieves uniform dosing of the one or more additives in the extrusion direction in the polymeric host material without homogeneously mixing the one or more additives and the polymeric host material. The apparatus for directly injecting one or more additives into a polymer melt stream comprises a pumping system, a die assembly having a thin-plate assembly, and a distribution line.

A lamp socket system 1 is provided for mounting an associated lamp 20, 20′ by holding a base 15 of the lamp through engagement between a set of connection pins 8, 8′ extending outwardly from the lamp base and a set of bayonet catch contacts 17, 18. The lamp socket includes a main housing body 2 and a substantially cylindrical coding ring 3, 3′ selectively connectable with the housing. The cylindrical coding ring 3 includes a set of recesses 10, 10′ arranged on an inner circumference of the coding ring at positions corresponding with positions of the set of connection pins 8, 8′ extending from the associated lamp socket base 15. The set of recesses 10, 10′ are adapted to receive the set of bayonet catch contacts 17, 18 associated with the lamp socket. A plurality of cylindrical coding rings are provided for selective connection with the main housing body to provide a convertible lamp socket system.

A process for producing thin absorbent planar structures which may be used in hygiene products such as diapers, incontinence products, wound contact materials or sanitary napkins to absorb body fluids, comprises the steps of: A) producing a mixture of an adhesive in dispersion form and a particulate absorbent by fluidizing the components, B) applying the mixture of adhesive and absorbent uniformly to the surface of one side of a first planar backing material, C) one side of a second planar backing material is applied to the mixture of adhesive and absorbent that is present on the surface of one side of the first planar backing material, so producing a sandwichlike intermediate, and D) the sandwichlike intermediate is processed to the end product at a temperature of at least 90° C., a pressure of from 4 to 50 bar, and a pressing time of from 0.5 to 5 min.

The invention concerns an electromechanical lock cylinder that cooperates with evaluation electronics to recognize access authorization and has a housing that includes two opposite cylindrical receptacles, in which a lock core, which can be operated by a key, or a knob shaft, which is connected to rotate in unison with a know, are mounted to rotation, in which the lock core and/or knob shaft cooperate with a lock tab, which operates, in particular, a bolt or latch with a door lock, and, with a fitting key or access authorization, an electromechanically driven blocking or coupling element is moved from the rest position to an operating position and produces a splined connection between the key or knob and the lock tab, characterized by the fact that the lock tab is freely rotatable relative to the two lock cores or the two knob shafts in the rest position of the blocking or coupling element.
摘要:
In the case of a fluidic nozzle (12) a nozzle body (13) is fixed in a housing (17) by a form-locking latching connection (18). For this purpose, an elastically deformable latching body (14) engages in a recess (16) of the housing (17). The operational position of the nozzle body (13) is thereby defined with high accuracy, with the result that an undesirable escape of the liquid between the nozzle body (13) and the housing (17) is prevented. Furthermore, at the same time the contact surface can be reduced here to a section (20) which is inclined toward an outlet opening (19) of the fluidic nozzle (12) and has a correspondingly improved sealing.
