Abstract: 1,239,976. Endless conveyers for shifting earth. CATERPILLAR TRACTOR CO. 10 July, 1968 [27 July, 1967], No. 32900/68. Heading B8A. [Also in Division E1] An earth-moving bowl-type scraper comprises an elevator movably mounted on the bowl of the scraper, power means for moving the elevator relative to the bowl, and control means which automatically operates the power means in response to a predetermined change in a force acting on another component of the scraper. In a first embodiment the bowl has a pivotally mounted floor 34 which is moved backwards by jacks 38 when the bowl is to be emptied. The elevator 12 includes endless chains 49 having. flights 51 and driven by a rotary hydraulic motor 53, and it is mounted on the bowl by means of pivoted links 54 and angled arms 59 and links 62, the latter being connected to side walls attached to the floor 35 so that the elevator is moved in a forward and upward direction when the floor is moved backwards. Jacks 66 are provided for moving the elevator relative to the bowl, and are automatically operated when the hydraulic pressure to the motor 53 reaches a predetermined level and so operates a control valve to pass fluid to the jacks, Fig. 2 (not shown). The elevator is therefore moved upwardly in response to increased pressure on it from the material passed into the bowl. Means are provided to retain the elevator in the raised position when the jacks 38 are actuated to empty the bowl, and to put the jacks 66 under manual control. In a second embodiment, Fig. 3 (not shown), the scraper has a main bowl to the front of which is pivoted a smaller auxiliary bowl, the rear wall of the main bowl defining an ejector which is moved forwardly to empty the main bowl when the auxiliary bowl has been pivoted away from the main bowl. Jacks respectively operate the ejector, pivot the auxiliary bowl and connect the upper end of the elevator to the main bowl, the lower end of the elevator being link connected to the auxiliary bowl. The jacks and the elevator motor are supplied from two pumps under the control of three manually operated valves whereby selectively the motor is supplied from one of the pumps to give it a low speed or is additionally supplied from the other pump to give it a high speed, the elevator jacks are supplied from the feed line to the elevator motor to raise the elevator or the elevator is held in position or is allowed to drop slowly, and the ejector jack and the jacks for the auxiliary bowl are operated to raise the latter and to empty the main bowl, a supply from the feed line to the ejector jack being taken to the elevator jacks from a point preceding a pressure-operated valve in the feed line so that the elevator is raised before the ejector is operated.

Title: Triggering circuit

Abstract: 1391799 Interference suppression circuits for x-ray exposure control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 July  1972 [17 July 1971] 33025/72 Heading G1A An interference suppression circuit for a measuring amplifier comprises a differentiator followed by a multi-stage switching amplifier including an RC circuit for stretching the length of the pulse and an output stage for disconnecting or short circuiting the input of the output stages of the measuring amplifier. In an automatic exposure control for an x-ray system flash-overs in the x-ray tube cause interference pulses which can prematurely terminate the exposure period. As shown, Fig. 5 the output of one of two ionization chambers 7 and 8 measuring x-ray intensities is selected by a switch 9 and applied via a low pass filter 10 to a mixer stage 12 and a bandpass filter 11 tuned to the ripple frequency of the high voltage supply to the x-ray tube. This ripple is subtracted from the main signal which is then integrated in mixer 10. The signal is then applied to a comparitor 13 which  triggers an output switch 15 when the input exceeds a reference voltage. Interference spikes which might cause the comparitor to trigger the output switch are suppressed by the circuit 17 which either short circuits the input of the comparitor or disconnects it from the mixer stage 12. In the embodiment of circuit 17 shown in Fig. 6 the charging current through capacitor 20 is also passed by transistor 32 through resistor 21 the voltage across which is therefore proportional to the rate of charge of the input voltage at point 19 so that the circuit constitutes a differentiator. On receipt of a positive going interference spike the voltage across resistor 21 is great enough to switch on transistor 22 and hence transistor 23 which in turn switches on transistor 24 to short circuit the input to the comparitor. The output transistor 24 remains conducting after transistors 22 and 23 have switched off until capacitor 28 has discharged through resistors 29 and 30 so that the comparitor is blanked for the duration of any sequence pulses occurring after the main interference spike.

A transducer for measuring displacement controls the resonant frequency of a tuned circuit incorporated in a phase discriminator whose output voltage is therefore indicative of the magnitude and direction of the displacement. As shown (Fig. 1), the phase discriminator comprises two diodes 6, 7 whose cathodes are fed with A.C. from an oscillating valve 2, and whose anodes are fed with the vector sum of the voltage obtained through the coupling between tuned circuit 3 in the anode of valve 2 and tuned circuit 4, 5, and the voltage developed across resistor 10. Initially the diodes 6, 7 produce equal and opposite voltages across resistors 8b, 9b, giving zero indication on meter 16. The resonant frequency of tuned circuit 4, 5 is modified by a coupling coil 12 connected to an inductor 14 and capacitor 15 whose capacitance is changed by the displacement, whereby a resultant output voltage is produced across resistors 8b, 9b indicative of the change in capacitor 15, and therefore of the displacement. The displacement can be made to vary the inductance or the resistance of the external circuit 14, 15.
