Abstract: 1,258,873. Telegraphy. NATIONAL CASH REGISTER CO. 24 March, 1970 [1 April, 1969], No. 14066/70. Heading H4P. Frequency-shift telegraph signals whose shift is jitter free are generated by a bi-stable device which is switched by a cycling counter reaching a predetermined count, the counter being driven at one of two rates dependent upon the level of a binary data signal. If two rates of clock pulses for driving the counter can be provided whose ratio is equal to the ratio of the frequency-shift signals required only a single counter is necessary otherwise two counters are required as shown in Figs. 1a and 1b. Counter 31 provides an output at a count of 30 via NAND gate 58 and counter 33 provides an output at and above a count of 56 at NAND gate 82. Clock pulses applied at input 10 are frequency divided by bi-stable circuits 12, 16 to drive via NAND gates 34-38 the counters at full, ¢ or “ clock frequency according to the level of the data signal at input 20. For a mark data signal counter 33 is driven at ¢ clock frequency and via NAND gates 86 and 62 switches the bi-stable circuit 98 at <SP>1</SP>/ 56  of this frequency. Counter 31 meanwhile is driven at “ clock frequency but merely idles. For a space data signal counter 33 is driven at full clock frequency but due to the inhibiting of NAND gate 86 by the space data signal counter 31, driven at ¢ clock frequency switches bi-stable circuit 98 at <SP>1</SP>/ 30  of this frequency. The output of either counter at NAND gate 62 resets both counters. Upon a change in level of the data signal the control of the switching of the bistable circuit 98 passes to the previously idling counter. The specification shows why because of the particular ratio of the predetermined counter the shift is substantially jitter free.

Abstract: 1,259,234. Combine harvester. F. WIENEKE and M. EIMER. 6 April, 1970 [5 April, 1969], No. 16124/70. Heading A1F. A threshing process control installation for a combine harvester in which the rate of threshing is automatically varied in response to the signal from a sensor on the crop elevator means, and the speed of harvester travel and concave cylinder gap, is automatically adjusted in response to variation in crop intake rate, or crop humidity or ingress of foreign bodies comprises a sensor 7 on the elevator 4 of the header responsive to crop intake rate which feeds a signal to a comparator 9, where it is combined with a signal from a speed sensor on the threshing cylinder 5, and an allisation in crop intake rate causes the cylinder speed to alter after a time delay equivalent to the time taken for the sensed crop to reach the cylinder plus the time taken for the cylinder to reach its new speed by delayer 12 and non linear amplifyer 13. A crop moisture sensor 16 feeds a signal to a summator 19 where it is added to a standard signal chosen for the type of crop on a console 18, the sum controlling the delay time, the range of increase or decrease of threshing rate and the concave gap to ensure optimum threshing conditions. The concave gap is measured by feeling elements 21 and altered by adjusting device 25 fed from a comparator 23 under the control of summator 19. The overall crop throughout is sensed by a torque sensor 26 on the threshing cylinder shaft which, under the control of summator 19 and console 18 alters the harvester ground speed via gear box 32 so that an increase in torque results in a slower speed. Raising the harvester header cuts out the control systems described above, and if the harvester threshing capacity is not used to optimum, a visual or audible signal is made on console 18 so the operator can reset the harvester ground speed. If foreign bodies are picked up and overload occurs, the throughput sensor 7 and torque sensor 26, via a limit transmitter 33 cause a visual signal to be set and after a time lag the threshing gap is set to maximum, and if the blockage is still present, the crop intake mechanism is stopped and the harvester halted. The installation may have hydraulic, pneumatic or preferably electronic analogue or digital control components.
