Abstract:
Described is an infusion bag comprising a layer made of nonwoven fabric composed of bicomponent fibers and/or filaments composed of a high-melting component and a low-melting component, the high-melting component including a polyester. Problems in the fabrication of the nonwoven fabric are avoided by the fact that the low-melting component includes a likewise high-melting polymer having a melting point ≧200° C.
Abstract:
In a fluid cylinder (1), the piston (2) and the piston rod (3) can be displaced axially by a fluid. Means (5, 7) are located on the fluid cylinder (1) which convert the axial motion of the piston (2) and the piston rod (3) to a rotational motion.
Abstract:
In the case of a locking mechanism (1) for a vehicle seat, in particular for a motor vehicle seat, having a pivotably mounted pawl (11) for locking to a mating element (B), and having at least one securing element (25, 31) which secures a locked state by interaction with a first functional surface (21) of the pawl (11), and secures an opened state by interaction with a second functional surface (41) of the pawl (11), the securing element (25, 31) exerts an opening moment on the pawl (11) in the opened state.
Abstract:
The present invention relates to a process for preparing 2-haloalkylnicotinic acids and haloalkylnicotinic acid derivatives starting from halomethyl-substituted enones and 3-dialkylaminoacrylic esters and also to intermediates of the process according to the invention.
Abstract:
In a method for the pretreatment of work pieces having a surface made of aluminium or aluminium alloys, for non-cutting shaping and/or the connection by welding or gluing to work pieces as well as for a subsequent permanent corrosion-preventing treatment, the work pieces are subjected to a three-stage treatment by a) rinsing with an aqueous, acidic solution containing a mineral acid, b) rinsing with water, c) bringing them into contact with an aqueous, acidic solution which is chromium-free and polymer-free and contains Ti and Zr as complex fluorides in a weight ratio of Ti:Zr of 2:1 to 1:2, in such a way that, after the subsequent drying off, a layer weight of 2 to 15 mg/m2 (calculated as Ti/Zr metal) results, wherein depending on the type of application, solutions having different concentrations and different pH values are used.

Abstract:
Fluorine-containing phenethylamines are obtained in an advantageous manner by reacting fluorine-containing bromobenzenes with acrylamide in the presence of a palladium catalyst, hydrogenating the resulting arylacrylamides catalytically and then rearranging the arylamides obtained. The invention also embraces novel arylacrylamides and novel arylamides.
Abstract:
The present invention relates to a process for preparing fluorine-containing phenethylamines which is characterized in that, in a first step, a substituted bromobenzene is reacted with an N-vinylimide in the presence of a palladium catalyst, in a second step, the resulting substituted &bgr;-iminovinylbenzene is hydrogenated catalytically and in a third step, the substituted &bgr;-iminovinylbenzene obtained in the second step is cleaved. This process also provides access to novel &bgr;-iminovinyl- and &bgr;-iminoethylbenzenes.
Abstract:
The invention relates to a sensor (9) for detecting a torque (13) exerted on a torsion element (10) and acting about an axis of rotation (8), comprising:
a transmitter element (16) which can be mounted in a stationary manner relative to a first axial end of the torsion element (10) and is designed to output a transmitting field (17) which can be varied in the peripheral direction (24) about the axis of rotation (8), a sensor chip (18) which can be mounted in a stationary manner relative to a second end opposite the first axial end of the torsion element (10) and is designed to output a measurement signal (20) which is dependent on the transmitting field (17) arriving at the sensor chip (18), and an evaluation device (21) which is designed to output a sensor signal (19) dependent on the torque (13) on the basis of the measurement signal (20), wherein the sensor chip (18) is arranged at an axial distance from the transmitter element (16), radially overlapping same.
