Title: Code generator
IPC: G06F7/58
Filed: 1973-05-03
Abstract: 1435746 Acoustic surface wave devices STANDARD TELEPHONES & CABLES Ltd 25 April 1974 [3 May 1973] 21070/73 Heading H3U [Also in Division G4] A pseudo-random binary code generator comprises a bit rate clock 18 driving an impulse generator 17 whose output is introduced as phase modulated r.f. signals into a surface acoustic wave delay line having tapping transducers 16a-16g along its surface. The output signals from two tapping points are each compared with a respective phase reference signal and the resultants are fed via respective detectors 22, 23 to a modulo-2 adder 24 whose output is used as a feedback signal for a polarity switching device 19 which varies the phase modulation of the r.f. signals emitted by input transducers 12. The arrangement of comparing the output and reference signals overcomes errors introduced by temperature effects. In a first embodiment, Fig. 1, the tapped signals from transducers 16d, 16g are compared in surface wave devices 20, 21, with the outputs of transducers 15d, 15g which are in corresponding positions on a second delay line parallel to the first and having an input transducer 11 which directly receives the output of generator 17. Each device 20 21 comprises two input transducers (27, 28, Fig. 2, not shown) equally spaced from an output transducer (29) so that an output is or is not obtained according to whether the input signals are in phase or antiphase. In operation of the binary code generator, device 19 is initially under the control of a starting pattern source (not shown) and once the device has received the required number of bits, it is under the control of the feedback signal. In a second embodiment (Fig. 3, not shown) each pair of transducers 15a, 16a &c. is replaced by a single transducer 30a &c., which extends across the both delay lines, tapped signals being fed directly from two transducers (30d, 30g) to the detectors 22, 23. A third embodiment (Fig. 4, not shown) has only one delay line, the output signal at 16d, for example, being compared with a signal from an adjacent transducer 16c. The separation between transducers 16c, 16d is arranged to correspond to one bit period. In a final embodiment, Fig. 5, the output signal from each tapping transducer 16d, 16g is divided into two inputs to a respective device 51, 52. Devices 51, 52 are similar to devices 20, 21 but with one input signal being delayed by one bit period with respect to the other by arranging the input transducers (60, 61, Fig. 6, not shown) at different distances from the output transducer (62).

Filed: 1964-05-22
Abstract: A method of making superconducting wires or bands from a titanium-niobium alloy of 20-45% by weight of niobium, the remainder titanium, is substantially the same as that disclosed in the parent Specification, but the claims are directed to the heat treatment being carried out between 300 and 450  DEG C., preferably between 350 and 400  DEG C.  The alloy is cooled down from a temperature in the b phase region, e.g. between 700 and 1100  DEG C., more preferably 1100 DEG C., so rapidly, e.g. in water, that such b  phase is retained and in addition a martensitic but no equilibrium a  phase is produced and after cold working the wires formed thereby are heat treated between 300  DEG  and 450  DEG C. to cause the supersaturated b  and martensitic phases therein to separate out.  The duration of heat treatment varies between 10 and 100 hours and preferably between 15 and 30 hours.  The superconducting properties of the wire at a temperature of 4.2  DEG K. in tests lasting 200 microseconds with and without a magnetic field are given in tabular form.
