Abstract: In an FM television signal angle modulated with luminance and chrominance information, there exists a high degree of correlation between picture elements occurring one line period apart. In an effort to steer the pass band of a tunable bandpass filter to the instantaneous frequency of the incoming television signal, a steering signal is developed which utilizes this high degree of correlation. For NTSC systems, luminance information is delayed by one-line period (63.5 us in the U.S.A.) and combined with suitable delayed chrominance information to form the filter's steering signal. For MAC systems, one-line delayed luminance and two-line delayed chrominance information are alternately applied to the filter as its steering signal. By steering the pass band of the filter to the incoming signal, maximum signal will be captured with minimum noise, enhancing the signal-to-noise ratio of a color television system.

Abstract: The present invention relates to a process for controlling the movements of a vehicle-mounted ladder, particularly a rescue and firefighting ladder, comprising a ladder formed from a plurality of elements capable of being extended or retracted by means of an actuator and of being raised by pivoting about a substantially horizontal axis by the agency of an actuator and being oriented about a substantially vertical axis by the agency of an actuator, and an electronic microprocessor system receiving at its input the signals from a control desk equipped with manual raising/lowering, extension/retraction and orientation control members and the signals representing the effective load exerted on the ladder, the developed length and the angle of orientation and generating at its output signals serving for controlling the actuators. The method according to the invention is characterised in that it involves calculating from the signals of the sensors a first speed coefficient which is a decreasing function of the developed length of the ladder, a second coefficient which is a decreasing function of the effective load and a third coefficient which is a decreasing function of the slewing radius of the ladder, calculating a maximum raising/lowering speed value from a maximum speed value adapted to the minimum developed length and to the minimum effective load and weighted by the first and second coefficients, calculating a maximum orientation speed value from a maximum value adapted to the minimum slewing radius and to the minimum effective load and weighted by the second and third coefficients, and supplying to the actuators control signals which do not exceed the maximum values thus calculated. <IMAGE>

Abstract: Circuit protection devices which contain PTC conductive polymer elements and which are used in situations in which the device is mounted onto, or itself comprises, a rigid wall which is spaced apart from the PTC element and through which the electrodes pass. The behavior of the device can be adversely affected if the electrodes, which are prevented from moving by the rigid wall, prevent the PTC element from expanding to the extent necessary to provide the desired PTC effect. The invention includes the use of specially designed electrodes which lessen the danger that the PTC element, when it is tripped, is prevented from expanding to the extent necessary for effective operation.

Abstract: Regulating the injection moulding process in a hydraulic injection moulding machine, involving switch over from injection to holding pressure as the flow rate (Q) is suddenly reduced, utilises a pressure-measuring unit for the pressure (P). The period between the instant at which injection flow rate changes to holding flow rate and the instant at which a predetermined pressure or the resultant change in pressure is reached, or an associated signal, or alternatively the period between the first time a predetermined pressure is reached as the flow rate is reduced and the second time this same or another preselected pressure is reached, are determined; alternatively the stroke of the injection piston at the instant of flow reduction is measured. The change in the piston stroke until the time when a predetermined pressure or the pressure before reduction in flow is reached, or the pressure difference value between maximum pressure at flow reduction and minimum pressure after this reduction is determined; these are used as comparison variables for regulating the process.
