Abstract: An apparatus for measuring parameters in a moving fluid, said apparatus comprising a hollow body (2, 6, 11) with an inner measuring chamber (12) through which the fluid moves, and a measuring cell (3) disposed in said body and having an active surface (4). To reduce the volume of the measuring chamber (12) and to obtain therein a fluid flow distribution ensuring accurate measuring results, the apparatus (1) is provided with a flow distributing means (8) having a through passage (15) into which the fluid moves via an inlet (9). In the measuring chamber (12) which is defined by the surface (4), the upper end surface (13) of the means (8), and a sealing ring (14) arranged therebetween, the fluid flow is, via the upper outlet of the passage (15), first directed axially against the active surface (4) and is then radially and uniformly distributed along said surface. Subsequently, the fluid flows in the opposite direction into an annular gap (20) and, finally, out of the apparatus (1),via an outlet (23, 10). Thus, the outlet of the passage (15) in the flow distributing means (8) forms the inlet of the measuring member (12), whereas the annular gap (20) of the means (8) constitutes the outlet of the measuring chamber (12). The fluid thus moves in a closed system, and a radial flow is obtained in the measuring chamber.

Abstract: The present invention combines the advantages of a prior art figure of 8 winding pattern with the traditional circular or oval pattern for packaging flexible cord to form what can be called a "figure of 80 pattern" which includes a generally S-shaped partial cord layer with the end of the S joining with a J-shaped portion arranged so that the straight portion of the J forms a continuation of the S and the curved portion of the J overlies the beginning of the S-shaped portion. This basic combination of S and J shapes designates only partial layers, the pattern can be repeated, that basic pattern can be connected to a plurality of oval turn layers or even a plurality of figure 8 turn layers as the user may elect. It is also possible to continue to merely alternate the basic layer form to provide a package having a high packaging density while permitting easy accommodation of fittings which are secured to the end of the cord.

Abstract: An error detection system for a discrete receiver. Sequences of bits together forming frames of information comprise the signal received by the discrete receiver. The signal is decoded by a convolutional decoder and is re-encoded by an encoder. Successive portions of nonoverlapping sets of adjacently positioned bits of the re-encoded signal formed by the encoder are compared with corresponding bits of a signal representative of the signal received by the receiver. When excessive numbers of the successive portions of the signals which are compared include bit dissimilarities, a bad frame indication is generated.

Abstract: The procedure for controlling the torque of an IC engine has a control unit which affects both the air admission and the ignition timing depending on a load demand signal. Before any load change, first adjustments of the intake air flow and ignition timing are made in the direction of reduced engine efficiency, while the engine torque remains constant. This is done by temporarily increasing the airflow and retarding the timing.   With the load change, the ignition timing is changed to its output value. Instantaneous deviations of torque or speed are compensated for by control circuits. The value for the change in airflow is corrected in proportion to the deviation of the adjusted ignition timing point from ....

Abstract: In an automatic predistortion adjusting circuit, a splitter splits an input signal into first and second signals. A predistortion circuit applies first non-linear characteristics to the first signal, a variable attenuator adjusts an amplitude of an output signal of the predistortion circuit, a variable phase shifter adjusts a phase of an output signal of the variable attenuator, and a main amplifier amplifies an output signal of the variable phase shifter, so that second non-linear characteristics opposite to the first non-linear characteristics are applied to an output signal of the main amplifier. A directional coupler takes out a part of an output signal of the main amplifier as a branch signal, and a delay line delays the second signal. An adder adds a delayed signal passed through the dely line to the branch signal. Further, a detector detects an strength of an output signal of the first adder, and a control circuit controls the first non-linear characteristics, an attenuation amount of the variable attenuator and a phase amount of the variable phase shifter in accordance with an output signal of the detector.
