Title: Detection of errors in digital signals
IPC: H04L1/24
Filed: 1976-05-12
Abstract: 1530406 Data transmission; testing POST OFFICE 6 Mav 1977 112 Mav 19761 19544/76 Heading H4P In contrast to prior disclosures for line testing (e.g. Specification 1,281,390) where each bit in a sequence (e.g. pseudo-random) is compared with a combination of two or more preceding digits originally related thereto by a determined function, in the present arrangement one or more comparison in every n (where n is an integer #2 related to the number of bits composed) are omitted. This can avoid repeated error detection as the faulty digit progresses through the comparison sequence. In Figure 3 a (2<SP>25</SP>-1) pseudo random sequence is applied to a line which terminates at 25 in a device 25 distributing incoming bits sequentially among terminals 26-28. A function of a 2<SP>25</SP> - 1 sequence is that bit Bn equals the mod-2 combination of Bn - 22 and Bn - 25. Register 29 receives every 3rd bit and is clocked at 1/3 incoming bit rate, hence with Bn at terminal 27, stage S7 stores Bn - 22 and S8 stores Bn - 25 which are combined in mod-2 adder 20 and compared in another mod-2 adder 31 with Bn for inequality when an output is given on line 32. Other arrangements (e.g. for a sequence 2<SP>15</SP> - 1) are described in the specification. In all embodiments the registers, which may be of delay line type, are clocked at a fraction of incoming bit rate.

Filed: 1929-06-28
Abstract: 334,981. Turner, J. E., and Hodson, C. F. June 28, 1929. Aeroplanes; ornithopters; propelling; controlling.-An aircraft having wings with spars extending continuously from tip to tip and rocking about a central longitudinal axis, employs a mechanism embodying cranks or eccentrics and connecting-rods connected to the spars in such a manner as to give a harmonic variation of pitch during the up and down movements of the wings. The front and rear spars of each wing are connected by rods A, B, Fig. 4, to cranks C on worm-wheels D driven from a longitudinally-disposed worm shaft. The pitch corresponding with any vertical position of the wings is controlled by the relative angular position of the cranks C. This may be adjusted during flight by moving the worm-wheels operating one set of rods A or B towards or away from those operating the other set whilst maintaining them in mesh with the worm shaft. The pitch of the wings may be reduced to zero for obtaining gliding flight. Any number of wings may be fitted and each may be of monoplane or biplane construction.
