Abstract: 2.1. Known electromagnetically actuated valve devices for controlling the connection between a hydraulic fluid source and a consumer system (inlet valve) or for controlling the pressure relief of a consumer system, have the disadvantage that they have only limited suitability for finely adjusting the consumer pressure, since they operate with a relatively large pressure drop between the inlet pressure and the consumer pressure with a large flow rate, which leads to the consumer pressure overshooting and undershooting. Other known valve devices of this type have a consumer-pressure-dependent response and therefore likewise have only limited suitability for the described purpose. The invention proposes solutions which permit fine adjustment of the consumer pressure in each consumer pressure range. 
<??>2.2. The invention proposes that the opening cross-section of an initial control valve, known per se, be made continuously adjustable by means of an actuating magnet, likewise known per se, having a flow- dependent movement characteristic; it is additionally proposed that the opening cross-section of a main valve, known per se, also be made continuously adjustable as a function of the flow, by coupling an initial control valve member in a fixed manner to a main valve member. 
<??>2.3. An advantageous area of application of the invention is for electrically controlled and/or electrically regulated motor vehicle brake systems (for example anti-lock braking systems).

For this purpose, the labels are provided with at least one substance which can be activated to adhere to the article. A distinction is made between a first substance, which makes the mechanical removal possible, and a second substance which is applied to the back thereof and possesses adhesion-promoting properties. The first substance is a release layer which is proof against water of condensation and has a particular solids content and a processing viscosity which is selected in a defined manner. The second substance, which imparts adhesive properties, is applied in the form of a gluing pattern, with a glue pallet offset backward along the edges of the label, in such a manner that removal forces are obtained for the label of between 2 and 8 Newtons. <IMAGE>

Abstract: A receive coupler for a binary data communication system that transmits signals in rectangular waveform on a data bus (11) is provided. The receive coupler includes a transition and polarity detector (17) that differentiates received signals and produces an output pulse on one or the other of two output lines (21a and 21b) for each transition of the received signal, the output line being dependent upon the rise-fall direction of the transition. That is, rise transitions create pulses on one output line (21a) and fall transitions create pulses on the other output line (21b). The receive coupler also includes reconstruction logic (19) connected to the output lines of the transition and polarity detector (17) that reconstructs the receive signal based on the pulses. The pulses are created in the transition and polarity detector by two differentiator-comparator combinations. One differen­tiator-comparator combination differentiates transitions of the rectangular waveform data signals amplified by a receiver amplifier (15) and produces a pulse when rise transition exceeds a threshold level and the other differentiator-comparator combination differentiates transitions of the rectangular waveform data signals amplified by the receiver amplifier (15) and produces a pulse when fall transition exceeds a threshold level.

Abstract: The detection of compounds containing both nuclei of a kind which exhibit nuclear magnetic resonance (nmr) and nuclei of a kind which exhibit nuclear quadrupole resonance (nqr), for example compounds containing both ¹H and ¹⁴H nuclei, is carried out by subjecting a substance suspected of containing such a compound to a magnetic field and repetitively to three parallel activities A,H and B. Activity A comprises two similar rf pulse sequences P A  and P B  at the nmr frequency. Activity H is a temporary change in the value of the magnetic field, which may be a reduction to zero. Activity B is the application of additional rf signals. Activity H and/or activity B are different during each of the respective pulse sequences P A  and P B . The activity B rf signals are at one or more frequencies selected so that in combination with the activity H in at least one of the pulse sequences the subsequent nmr signal is modified if such a compound is present. The difference in magnitude of the nmr signals obtained following the two types of rf pulse sequence is then measured.

Abstract: Rotary motion from a drive motor (12) is coupled by a coupling means (8) to a driven member (18) extending from a centrifuge bowl (40) and extending through an opening in an enclosure (20). The coupling means (8) comprises a non-rotational member which translates, or orbits, about the bowl axis (A). A flexible boot (16), extending from the coupling means (8), seals the opening in the enclosure (20) through which the driven member (18) is driven. By this means, centrifugal separation of biological fluids such as blood is achieved without rotary seals for the introduction of the fluids into the bowl (40).

Abstract: An improved multifilamentary fibrous material is formed having solid particles of a matrix-forming thermosetting resin substantially uniformly dispersed among adjoining filaments in the absence of fusion bonding. The thermosetting resin particles initially are dispersed in an aqueous medium containing an effective amount of a dissolved polymeric binding agent and the viscosity of the medium subsequently is substantially increased to at least 50,000 cps. to form a gelled impregnation bath having a plastic flow characteristic with shear-thinning behavior wherein the thermosetting resin particles are substantially uniformly suspended. The resulting impregnation bath is caused to flow between the adjoining filaments of the multifilamentary fibrous material with a concomitant viscosity reduction which aids in the incorporation of the resin particles. The concentration of the aqueous medium in the product is controlled to yield a uniform, handleable, drapable, tacky, and highly stable product. Upon the application of heat and pressure the improved product can be transformed into a fiber-reinforced composite article herein the thermosetting resin forms the matrix phase.
