Title: Data Transmission System
Inventor: FREY ALEXANDER H JR
IPC: H04L1/00
Filed: 1967-12-13
Abstract: 1,198,510. Polynomial error-correcting codes. INTERNATIONAL BUSINESS MACHINES CORP. 13 Dec., 1967 [15 Dec., 1966], No. 56950/67. Heading G4A. In a data transmission system a message consists of information digits and remainder digits obtained by dividing them by an errorcorrection coding polynomial, receiving means multiplying a received message by X<SP>a</SP> where a = p - (n-r) where p is the period of the coding polynomial, i.e. the smallest positive integer for which Xp - 1 is divisible by the coding polynomial, n is the number of digits in the message and r is the degree of the coding polynomial, and dividing by the coding polynomial to provide a remainder indicating any errors in the message. In one embodiment, the transmitter includes a linear-feedback shift register (with modulo-two addition) to obtain the remainder digits (bits) for the message, the information bits being effectively multiplied by Xr before division. Fig. 3 shows the receiver, including a linear-feedback shift register 39 (with modulo-two addition), feedback from its output (stage 100) being via AND 66, there also being feedforward from the input (top left) as shown, to accomplish the multiplication and division in one operation. The information bits (or the whole message) are also entered into buffer storage 52. When the remainder from the multiplication and division has been produced in the shift register 39, the contents of the buffer storage 52 are passed to the output 64 via modulo-two adder 62, in synchronism with shifting (with feedback) of shift register 39. Detection of all-zeros in the first (r - b) stages of shift register 39 (where b is the maximum length of a correctable burst of errors) by AND 54 causes the other bits in the shift register 39 to correct the corresponding bits from the buffer storage 52 at modulo-two adder 62 via AND 58, the feedback being disabled using inverter 68. As shown, n = 200 (100 information bits and 100 check bits), r=100, b=90. Portions of the shift registers may be replaced by delay lines. The buffer storage may be a shift register, delay line, or magnetic tape or core memory. A second shift register, similar to 39 but without the feedforward from the input mentioned, could be provided to control the correction, being fed from register 39 after the multiplication and division to allow register 39 to proceed with the next message. A second embodiment comprises a feedback shift register used for transmitter division and receiver multiplication and division alternately in interleaved fashion, intermediate results being held temporarily in a main store (magnetic disc, drum or cores) and a second feedback shift register being provided to control correction as above. Application to telephone and magnetic tape systems is mentioned.

Abstract: 1457506 Electric switch operating handles REYROLLE PARSONS Ltd 10 Dec 1973 [18 Dec 1972] 58427/72 Addition to 1403351 Heading H1N A high voltage switch has an operating shaft 51 that is rotated in opposite directions to open or close the contacts and a handle 30 for rotating the shaft that must be removed from the shaft, turned about its axis and replaced in a different attitude between, being used to rotate the shaft 51 in these opposite directions, to prevent the opening of the switch, if it is accidentally closed on to a fault current, before an automatic circuit breaker can act; the handle comprises an arm 31, and corresponding to the attitudes two cylindrical bores 36, 37 with abutments 39, 40 adjacent each bore having driving surfaces 41, 42 to engage corresponding surfaces 54A, 54B on an end of the shaft or a collar 52 on the end of the shaft. As shown in Fig. 4 bore 37 surrounds shaft 51 and clockwise rotation of the handle 30 brings driving surface 42 of abutment 40 into engagement with surface 54B of projection 53. The shaft 51 is then rotated clockwise to close the contacts of the switch. If the handle is then rotated anticlockwise, abutment 40 disengages from projection 53. There is lost motion before the other side of abutment 40 could engage projection 53 but this is prevented in any case by an abutment on switch housing 50. To open the switch contacts, handle 30 must be taken off shaft 51, rotated about its axis and replaced with bore 36 on shaft 51 shown in Fig. 5. Face 41 of abutment 39 can then rotate the shaft to open the contacts. The delay required in this operation is sufficient to permit an automatic circuit breaker to act. Flanges 52A, 52B on collar 52 permit the handle to be padlocked in one or other switching state of the switch.

Abstract: 636,596. Electric totalizators. UNION TOTALISATOR CO., Ltd., and HANDLEY, J. Oct. 16, 1946, No. 27749. [Class 40 (i)] [Also in Group XXXIX] An indicating device for use with the ratio computing device described in Specification 636,595 comprises a polarized rotor 33 mounted in the field of three electromagnets 29, 30 and 31, which are energized successively from segments 39, rotating with the computing device. Every segment is looped to another, three segments away, so that as the computer rotates, these segments, which may be of uneven length to allow for the non-linear indication of the computer, are successively earthed by the armature 32 of an electromagnet 40, thereby energizing magnets 29, 30 and 31 in turn and stepping round the polarized rotor. This rotor drives the wiper 35 of a telephone type marking switch through step-down gearing to cause a switch to hunt to indicate the odds on the display panels. The armature 32 may be continually lifted by a pulsing relay 40 so that frictional drag on the computing device is reduced. The wiper arm 35 may be fixed and the contacts 36 rotated. In this case wiper 35 can be lifted clear of the contacts when the rotor 33 is stepping round to reduce frictional drag. The indicator is of the type described in Specification 441,063.
