Abstract: An apparatus for opening textile fibre bales comprises at least one opening roll which is mounted rotatably within a housing which forms an aspirated conveyor shaft and which is open at its bale facing side. The direction of rotation of the roll is switchable in accordance with the particular direction of the movement of the housing relative to the fibre bales. A deflecting element arranged within the housing for the loose fibre and extending in the longitudinal direction of the roll deflects the loose fibre supplied at one side of the roll into the conveyor shaft, prevents the formation of false air flows and is mounted in such a way that it can escape in order to absorb impact due to foreign objects. The apparatus is distinguished by the fact that the deflecting element is configured as a pivotable flap which in the area of its roll facing longitudinal edge is attached at its end faces, via respective pivot axles, to respective deflectors so as to perform pivoting movements about an axis of rotation extending parallel to the longitudinal edge, that the two deflectors are pivotably mounted on the housing at their pivot axle remote ends, and that there is provided a device at at least one of the pivot axles for changing the direction of rotation corresponding to the pivotable flap.

Abstract: An arrangement is provided for checking the validity of a sensed-current signal (at 20) from a current-sensing device (24). The sensed-current signal (at 20) represents the current in a line (22). An associated control circuit (15,10) utilizes the sensed-­current signal (at 20) to indicate or predict the presence of undesired overcurrent conditions. When such conditions may be present, the sensed-current signal (at 20) is checked to determine if the sensed-current signal is valid; i.e., whether the sensed-­current signal (at 20) accurately represents the current in the line (22). If the sensed-current signal is invalid, no trip signal (at 25) is generated to interrupt the current (via 30). If the sensed-current signal (at 20) is valid, the control circuit (15,10) generates a trip signal (at 25) to control operation of a circuit-­interrupting device (30). In a particular arrangement, the load on the current-sensing device (24) is changed (via 35,40) to determine if the sensed-current signal is valid. If the sensed-current signal (at 20) is valid, the level of the sensed-current signal remains in a valid range and the control circuit issues the trip signal (at 25). If the sensed-current signal is invalid, the level of the sensed-current signal changes. In response, the control circuit (15,10) does not issue the trip signal (at 25) and is reset to an initialized mode to monitor for a valid overcurrent condition in response to the sensed-current signal. In a specific arrange­ment, the current-sensing device is an iron-core transformer which saturates at high current levels.

Abstract: A bandwidth reduction system for television signals employs three spatial filter circuits (7, 11, 12) capable of imposing respective resolution characteristics on the signals. The filters are selectively switched into the path of the signals in dependence upon the degrees motion occurring in respective spatial portions of the television picture. A relatively high resolution is allowed where virtually no movement is taking place and a relatively low resolution where rapid movement is taking place. Intermediate resolution is imposed where the degree of motion in a given spatial portion of the television picture is finite but less than said rapid movement.

Abstract: In an instrument wherein a sample in a solvent with a solute is interrogated for absorption by monochromatic light, a method and apparatus for electronically measuring and subtracting the effect of half order chromatic components is disclosed. The light is originally produced by a relatively broad spectrum light source having its spectral output separated to a monochromatic interrogating beam produced by reflection at an angle from a diffraction grating. Inevitably present in such diffraction grating produced chromatic light are half order light components. The process includes turning the diffraction grating with respect to the light source to have a primary output in the frequency of the half order component of the selected primary monochromatic frequency and taking a measure of the system absorption at the half order component. System absorption can be taken either by passage through the system free of soivent, solute and sample or alternatively passage through a reference cell containing solvent and solute within the system. The diffraction grating is then turned with respect to the light source to have a primary output in the primary monochromatic frequency. The ratio of primary monochromatic frequency to half order transmission (a known constant for any diffraction grating) is utilized to calculate the half order component in any selected primary monochromatic frequency. Thereafter, and for a sample in a solvent and solute, the log of the ratio of absorption of all light less the calculated half order light absorption for the sample in the solute and the solvent over the absorption of all light for the system less the calculated half order light absorption for the system is taken to describe relative light absorption. It is preferred to use a reference cell for the system absorption measurement to describe relative light absorption between the sample cell and reference cell. Utility can be present in comparing the absorption between   differing solvents, solutes or samples. The apparatus and method finds preferred utility in observing centrifugation induced separation through windows in a spinning rotor during the process of separation.
