[Class 107.] A tamping-machine is provided with main operating mechanism for raising and releasing the tampers and with auxiliary lifting mechanism adapted to lift the tampers off the road before the next lifting operation of the main mechanism. According to one construction, the machine comprises a main frame 1, Figs. 1 and 2, supported on wheels 3 and roller 2, and driven by a motor 4. The tampers 11 are mounted in guides 10 carried by an inclined platform 6 which is slidably arranged in guides 5 on the main frame. Adjustment of the platform is effected by handwheels 9 and threaded spindles 7. Mounted on the platform is the main operating mechanism, comprising a driving motor 16, lifting wheels 15, and intermediate gearing 17, 18, 19, 26, for driving the shaft 14 on which the wheels are mounted. In operation, pins 20 on the lifting wheels engage with and lift a plate 21 on the tampers, and the latter, when released, fall by gravity or by the action of heavy springs 22. The tampers are lifted immediately after they have struck the ground by the auxiliary operating mechanism comprising rotating members 23 attached to a shaft 24 which is driven by a wheel 25 meshing with the wheel 26 on the shaft 14. Each member is provided with rollers 27 which co-operate with the plate 21 until the latter is again engaged by the pin 20 of a lifting wheel. The shaft 24 is supported in horizontal guides 28 in the frame 1, which permit of movement of the shaft when the platform 6 is displaced. Such movement is effected by links 29 connecting the two shafts 14, 24, which links serve the purpose of maintaining the gears 25, 26 always in mesh. In a modification, Fig. 4, the guides 28 are arranged near the free ends of plates 48 which are so pivoted at 49 to the frame 1 that the guides are movable in a substantially vertical direction. The movement of the plates is effected by a handwheel 50, the screwthreaded shaft 51 of which carries a nut 52 connected to a lever 53. An arm 55 on the same shaft 54 as the lever is connected by a link 56 to the plate 48 so that the latter can be raised or lowered by manipulating the handwheel.

Abstract: 1420420 Measuring pulse repetition rate or period PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 April 1973 [28 April 1972] 19594/73 Heading H3H A circuit for measuring the pulse repetition rate (f M ) of a signal in a measuring interval (T 0 ) using a clock pulse train of frequency f t  comprises a first counter Z 1  fed with clock pulses and reset by the pulses to be measured f M , a second counter Z 2  fed with pulses f M  and reset by the measuring interval signals T 0  and an arithmetic unit R in which f M  is calculated from the equation where n is the count in the second counter Z 2  at the end of the measuring period, Z is the number of clock pulses in the measuring interval T 0 , and m 1  and m 2  are the readings of the first counter Z 1  at the beginning and end respectively of the measuring period. The counters comprise together a number of stages Z a  to Z m  and these are distributed automatically or manually according to the frequencies to be measured. Counter Z 1  is reset by each pulse of frequency f M  and the start and stop signals of period T 0  gate the counter readings at that time to store S a  . . . S j  and then to arithmetic unit R. Counter Z 2  is reset by the first " T 0  " pulse and its reading is transferred to R by the second T 0  pulse via stores S k  ... S m . The values m 1  and m 2  from counter Z 1  comprises the number of clock pulses between a pulse f M  and the start pulse T 0  (m 1 ), and a pulse f M  and the stop pulse T 0  (m 2 ) (see Fig. 1). A second system in which all measurement takes place within the measuring interval T 0  is described in Figs. 3 and 4 (not shown). In these, the number of clock pulses (m 3 ) between the start T 0  signal and the next f M  pulse is measured and so is m 2 . In the embodiment of Fig. 3, the value m 3  is determined in a third counter Z 3  and is entered into counter Z 1  after each f M  pulse so that the final reading in the counter at the T 0  stop signal is m 3  + m 2 . The first pulse to counter Z 2  is suppressed so that it records n-1 pulses. In the embodiment of Fig. 4, the number Z is initially entered into counter Z 3  and it and Z 1  both count downwards so that the final reading is Z-(m 2 +m 3 ). Counter Z 2  is preset to - 1 and counts upwards. This simplifies the calculation in unit R (for theory see Specification).
