Abstract: 1,050,340. Comparing digital data. RADIO CORPORATION OF AMERICA. Dec. 31, 1963 [Jan. 22, 1963], No. 51446/63. Heading G4M. In a circuit for comparing two binary words to determine which is the larger, a third word is produced in which the bit corresponding to the two bits of the same order being compared has a first value when the said two bits are equal and otherwise the second binary value, means being provided responsive to the bit of highest significance in the third word having the second value, for indicating which of the two input words is the greater. As shown, Fig. 1, two binary words A = a1a2a3 and B = b1b2b3 to be compared are applied as shown to a circuit comprising AND gates 10-15 and EXCLUSIVE OR gates 16-18, the EXCLUSIVE OR gates 16-18 produced an output word c1c2c3 such that a digit ci = 1 if and only if ai and bi are unequal. The word c1c2c3 is applied to a " selector " circuit 20, detailed in Fig. 2 (not shown), which produces in response to a timing pulse TP-1 an output word d1d2d3 in which all the digits are " 0 " except the digit (if any) corresponding to the highest order "1" bit in the word c1c2c3. The selector circuit comprises AND gates 32, 34, 36, the gates 34, 36 having inhibitory inputs. The word d1d2,d3 is applied as shown to the AND gates 10-15, Fig. 1, so that only the AND gates of the highest order in which there is a difference in the input bits are enabled, the particular AND gate responding to produce an output across a resistor 22 or 24 according as A > B or A < B. IFA = B THEN C1c2c3 = 00 and d1d2d3 = 000 so that no signal is produced across either of the resistors 22, 24, and a NOR gate 26 is operative to produce an output indicative of A = B. The selector circuit gates can comprise diodes and resistors (Fig. -3, not shown).

Abstract: 1,052,621. Cellulose fibres containing aminoethyl cellulose ethers. COURTAULDS Ltd. Oct. 8, 1963 [Oct. 9, 1962], No. 38115/62. Heading B5B. [Also in Division C3] Regenerated cellulose fibres contain aminoethyl and diethylaminoethyl ethers of cellulose. The aminoethyl ethers may be incorporated, or formed in situ, in the cellulose at any stage up to the finishing of the fibre. In a viscose process aminoethyl cellulose and diethylaminoethyl cellulose may be xanthated and added to viscose, or may be mixed with the cellulose or alkali cellulose before xanthation. Alternatively, compounds reactive with cellulose to form the ether in situ may be added nt suitable stages in the production. Specified reagents are 2-aminoethyl sulphuric acid, 2-chlorethanolamine and the corresponding diethyl compounds. In an example a mixture of aminoethyl and diethylamino-ethyl cellulose ethers is xanthated, ordinary viscose is added, and the mixture spun at a salt figure of 6À2. The fibres of the invention preferably contain at least 0À165% by weight of nitrogen derived from the amino ethers. The fibres have good dyeability.

Abstract: 1,225,747. Sonar and radar systems. THOMSON-C.S.F. 4 Feb., 1969 [5 Feb., 1968], No. 6019/69. Heading H4D. In a system for modifying the duration of a pulse in two successive steps, a converter gives an output signal of waveform similar to its input signal but of duration K times that of the input signal, and a dispersive delay device provide the other duration modification. The system is applicable to sonar (or radar) systems in which a sharp pulse is expanded to give a frequencymodulated (FM) pulse for transmission and in which FM echo pulses are compressed. In an exemplary system for compressing an FM signal S(t/K) of duration KT, the signal is repetitively   sampled at 3 and the samples E are written into a recirculating memory 2 by unit 4. Memory 2 may be one or more delay lines or shift registers, with the output connected back to the input, and notionally comprises K " memory cells " the content of each of which is periodically transferred to its neighbour. The sampling and write-in are controlled by timer 5 such that sample E i+1  is written into cell A when the previous written-in sample E i  reaches cell U, i.e. such that the sampling periodicity is greater than the memory circulation time # by the small quantity #/K. The samples appear at read-out unit 6 at intervals of #/K and are applied to dispersive delay line 1. Due to recirculation in memory 2, an input sequence of K cont secutive samples of input signal S(-) will be K distributed and repeated in K interlaced series of read-out samples and must be picked out from these series. To this end the output of delay line 1 is applied to coincidence circuit 7 whose control input receives control pulses with a periodicity equal to the duration of the said input sequence. Circuit 7 output has the envelope S<SP>1</SP>(t). For expansion of a pulse S<SP>1</SP>(t) to give an FM signal the system operation is approximately the reverse of that described above (as indicated by the dotted line connections) and certain of the system components can be the same as before, the pulse being fed through delay line 1 in the reverse direction to give an expanded signal which is further expanded in the recirculating memory (which now has a read-out periodicity less than T by the amount #/K). In practical embodiments of the compression or expansion system (Figs. 3 and 6, not shown) the signals in memory 2 are in binary form, the write-in and read-out units incorporate analogue-to-digital and digital-toanalogue converters, and the input or output of the dispersive delay line is additionally frequency-converted.
