    摘要: A process and apparatus for guiding a continuous moving tow in synthetic fiber manufacture. The profile (the thickness distribution and width) and the position of the tow are continuously sensed in a non-contact manner and an appropriate electrical signal is generated. This electrical signal is used to control the profile and the position of the tow in such a way that its profile and position stay within predetermined target value ranges. The tow geometry is preferably sensed using a CCD camera, while the tow geometry is controlled using tow-engaging deflecting means. In this way it is possible to optimize tow profile and position, for example for entry into a stuffer box (FIG. 1).

    摘要: The invention relates to a process for preparing wet- or dry-spun filaments and fibers of polymers which consist to more than 50% by weight of acrylonitrile units and which are continually treated with an aqueous solution containing copper(I) ions during the fiber production process but before a first heat treatment above 100.degree. C. and the copper content in the fibrous material is fixed by heating to above 60.degree. C., preferably to above 100.degree. C. The filaments and fibers thus obtained can be dyed with acid dyestuffs, have bactericidal properties, and can be subjected to accelerated pre-oxidation.

    摘要: To increase the responsiveness of a vehicle alarm system to, for example, unauthorized entry through windows, jacking up for removal of parts or vehicle theft as well violent impact by another vehicle, at least one position sensitive sensor has its output signal, which represents the instantaneous position of the vehicle stored after activation of the alarm system. Any change in that position is detected and triggers a warning device when the deviation exceeds a predeterminable amount. The position sensitive sensor may be a fluid-filled vessel the internal resistance of which is measured in a resistance bridge or it may be a variable inductance sensor which is connected to a frequency generator whose output signals are counted and compared with a given value. The system according to the invention may also serve as an accelerometer.

The method records a multiplicity of oil levels under specific operating conditions over time; calculates an oil-mass average value X.sub.z of the oil top-up quantity over z instantaneous measurements xmom in each case; calculates a compensating function describing the variation in an oil mass xh over time using a specific number of hourly oil masses xh; calculates a difference DFA from an end point xlang of the compensating function and from the penultimate oil-mass average value according to a function activates a discrimination function for checking whether the difference DFA is greater than a first oil-mass limit value M1; and if so, a special case is recognized and a processing function for calculating the oil top-up quantity in the special case is started; and if not, a further discrimination function is started, for checking whether the difference DFA is greater than a second oil-mass limit value M2 and there is a specific communication signal between the vehicle and driver. If the result of the check is that the difference DFA is greater than the second oil-mass limit value M2, a special case is recognized and the processing function for calculating the oil top-up quantity in the special case is started. If the interrogation result is negative, a processing function for calculating the oil top-up quantity in the normal case is activated.
