Title: Devices for synchronising telegraph signals
IPC: H04L1/00
Filed: 1972-09-25
Abstract: 1360148 Data transmission: synchronizing SIEMENS AG 25 Sept 1972 [23 Sept 1971] 44153/72 Heading H4P A receiver for telegraph signals whose bits are arranged in groups forming code words is synchronized by successively sampling groups of bits until a code word is recognized, each checked group being displaced by one bit position from the last checked group. The code in the described example is three 1's and four 0's in any seven bit word. Each group of seven bits to be checked A-G, B-H, &c. (Fig. 2) is clocked in at N b  by P o  to a 6-bit register 8, Fig. 1. Corresponding clock pulses P1, slightly delayed relative to P o , step onwards a divide by seven circuit 2 whose output 2h thus goes to 1 each time a multiple of seven is reached at t 7 , t 14 . A code tester 7 gives a 0 output at 7h only if a code word is present in register 8, and a 1 output otherwise. Thus AND gate 6 is enabled when a loss of code word (7h = 1) coincides with the end of a 7-bit count by divider 2 (2h = 1), this happening at t 14 . Inverter 5 thus gives out 0 to block AND gate 4 and stop the divider 2. PO continues to clock in new bits at N b  however, and when a code word is detected in register 8 at t 17  (FGJ = 1, HJKL = 0), the code tester output 7h goes to 0, 5h to 1 and divider 2 recommences. Every fourth code word is polarity-reversed at the transmitter, and corresponding reversal is effected at the receiver by circuit 9 when a divide-by-four circuit 3 produces an output 3h. Signal N b  is thus derived from the received signal Na. The necessary synchronization of this reversal is achieved by the above described inhibiting of the receiver divider loop 2, 3 until a code word is recognized. The code tester 7 (Fig. 3, not shown) cycles the complete contents of register 8, between successive clock pulses PO, round a loop from 8a through an AND gate 16, an OR-gate 20 back to 8g. A pulse train P2 containing eight pulses P21-P28, Fig. 4 (not shown), effects this. A further pulse P4 coincident with the first pulse P21 acts through an AND gate 18 to reset a counter 15 and effectively cancels the first stored bit 8a. The other six bits (8b-8g) circulate and any 1's are counted at 15. Finally one new bit from the received and corrected signal N b  is fed from an AND gate 17 enabled, as AND 16 is disabled, by a pulse P3 coincident with the last pulse P28 of the train. This new bit goes to register position 8g and is also counted by 15 if it is a 1. The output of the counter 15 is 0 only if a count of three is registered and is 1 otherwise.

Title: Servo-operated control systems for dirigible craft
IPC: G05D1/00
Filed: 1960-12-23
Abstract: 962,117. Automatic steering control. SPERRY RAND CORPORATION. Dec. 23,1960 [Jan. 6, 1960], No. 44291/60. Heading G3R. In a servo-system for steering a dirigible craft by actuating a control surface, a pulse generator applies test pulses to the system at intervals sufficient to allow resulting oscillations to subside to a low level, any variation in the pattern of these oscillations from a desired pattern being automatically corrected by adjustment of the gain of the system. In Fig. 1, signals from the pitch pick-off 18 of a gyro-vertical 17 on an aircraft are applied to a non-linear device 16 and a differentiator 15, the combined outputs of which are applied, through a potentiometer gain control 27 and a power amplifier 14, to a servo mechanism 10 adjusting elevators 11. Positional feedback from a signal generator 32 operated with the elevators is applied to the input of amplifier 14. A manually operated selector switch 40 may introduce, through a delay network 42<SP>1</SP> (a) signals from a manually adjustable device 47 to set a desired angle of pitch (b) signals from the pick-off of an aneroid bellows 43 to maintain a constant altitude or (c) signals from a radio receiver 36 to casue the aircraft to follow a radio landing path. Pulses from a generator 51 are added to the input of potentiometer 27 to cause the elevators to be oscillated a number of times during recurrent periods determined by a timer 57. These oscillations are detected by signal generator 32 the output of which is applied through synchronized gating, shaping and trigger circuits 60, 62, 75 to produce a corresponding number of incremental charges of a condenser 79. During the same period a number of pulses representing the desired response of the control system is produced by a counter 70 to cause a corresponding number of incremental discharges of condenser 79. Any difference between the actual and desired number of oscillations produces a voltage of corresponding polarity and magnitude across condenser 79 to operate a motor 80 which corrects the difference by adjusting gain control potentiometer 27. A brake 82 only releases to permit operation of motor 80 if the actual number of oscillations is low during two successive count periods but it releases immediately if the number is high in any one period. The periods for which the oscillations are applied may be automatically varied by controlling timer 57 in dependence on the rate of change of aircraft speed or altitude.

During the welding operation an increasing clamping force on the lugs and a decreasing force on the extrusion is effected. In apparatus as shown the lugs and partition assembly may be seen at the bottom of the Figure and the extrusion is effected by 2 substantially cylindrical electrodes 6. The lug clamping means comprise pads 32 of high density polyurethane and are arranged around the electrodes. The compression of the polyurethane provides the variable forces referred to above. The electrodes and lug clamps are held in holders 8 which are in turn held in slides 10. The slides are moved via pivoted arms 16 which are held together at toggle 23. Force from an hydraulic system, not shown, may be applied at the toggle to move the electrodes 6 together through the linkages. Each arm 16 contains a spring 26 which is "locked up" by the force applied to the toggle 23 and which provides the rapidly expandable energy to the electrodes 6 as discussed above.
