Title: Data transmission systems
IPC: H04L7/04
Filed: 1964-10-29
Abstract: 1,045,569. Checking and detecting errors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 29, 1964 [Nov. 29, 1963], No. 44070/64. Heading G4A. In a data transmission system, an n-bit transmitted word comprising (n-r) intelligence bits and rbits representing a remainder value derived from the division of the intelligence bits by a coding polynomial, is applied serially by bit to an n-bit delay circuit in a receiver which also comprises a dividing circuit operable to divide the word by the coding polynomial, a gating circuit being enabled to pass the intelligence bits from the delay circuit in response to detection of a predetermined bit pattern from the dividing circuit indicating that the word is correct and complete. Fig. 3 shows the receiver (greater detail in Fig. 5, not shown). The transmitted word, besides being passed into an n-bit buffer 202, passes to a modulo-2 adder 224, the output of which goes to the first stage and to modulo-2 adders preceding certain other stages of a shift register 225, the output of which is fed as a second input to modulo-2 adder 224. The register 225 and adder 224 perform the second division mentioned. On a particular pattern of ONES and ZEROES (the remainder of the division) being detected in register 225 by circuit 299, a gate 208 is enabled to pass the output of buffer 202 to output line 210. In order to obviate the necessity of framing bits preceding the word to reset shift register 225 prior to division of the word, the output of the buffer 202 is also fed to modulo-2 adders in the shift register 225 to cancel the effect of the bit received n-bits before that entering modulo-2 adder 224. Fig. 4 (not shown), shows the transmitter which feeds (n-r) intelligence bits received to an output line to be transmitted and also to a modulo-2 adder the other input to which is the output from the last stage of a shift register. The output of the modulo-2 adder goes to the first stage and to modulo-2 adders preceding certain other stages of the shift register, which divides the intelligence bits by the coding polynomial and stores the remainder. The contents of the shift register are subsequently passed to the output line as the last r-bits of the transmitted word. Two modes of operation are possible. In the first, with the transmitter operating as above, the predetermined pattern to be detected in the receiver shift register 225 is a sequence of all ZEROES. In the second, which is preferred because it enables correctly transmitted data to be distinguished from no data transmitted, the pattern is not all ZEROES. In this case the remainder calculated in the transmitter shift register is modified before transmission by complementing certain bits this being done by feeding a ONE bit to extra modulo-2 adders between certain stages of the transmitter shift register (on line 139, Fig. 4, not shown). It is also mentioned that different predetermined patterns may be associated with different transmitters, the receiver pattern detection means being selectively settable accordingly.

Abstract: 1,113,695. Transferring designs. LETRASET Ltd. 20 Oct., 1965 [30 Oct., 1964; 14 May, 1965], Nos. 44384/64 and 20497/65. Heading B6C. Indicia is applied to successive receptor surfaces, e.g. polythene bottles, by means of a tape fed from a reel and carrying ink indicia successively printed along its length, the indicia being partially released from the tape before application to the article by locally stretching the tape. The stretching may be effected by drawing the unprinted side of the tape over a surface of small radius or a serrated surface such as a bar having a helical thread or cylindrical ridges. Alternatively, the tape may pass between successive rolls driven at different speeds to tension it. An adhesive to cause the indicia to adhere to the receptor surface may be incorporated in the ink or cover the ink on the tape, or may be applied to the tape after the partial release of the indicia or to the receptor surface. When the adhesive is present on or in the indicia it is preferably non-tacky but is capable of being activated by pressure, or heat, or a solvent. The solvent may be applied either to the tape after partial release of the indicia, or to the receptor surface. For the tape, a light-transmitting film may be employed. Among the materials which may be used for the tape are various polymeric materials, paper, cardboard, metal foils, paper laminates and coated papers. A number of examples of suitable clear and coloured inks, and adhesives are given. Before use, the printed side of the tape may be covered by a protective strip of cellulosic material such as kraft paper, glassine paper, or vegetable parchment paper, having a coating on its face adjacent to the indicia which allows the strip to be readily released from the tape. An apparatus, Fig. 2, for applying the indicia comprises a tape supply roll 12, and a tape rewind roll 17, the latter being driven. The tape first passes over rolls 13, 14, and then the protective strip is separated and guided by rollers 15, 16 to the wind-up roll 17. The tape passes over (a) a bar 18 of small radius to effect partial release of the indicia, and (b) a roller 19 or a platen which applies the tape against the receptor surface. The articles to be marked are conveyed one by one beneath the apparatus which is reciprocated in the direction of motion of the articles to apply the indicia to the articles in turn. A simpler hand-manipulated apparatus, Fig. 1 (not shown), for applying the indicia is also described.

Title: An electrical system for controlling power
IPC: G11C11/42
Filed: 1964-11-05
Abstract: 1,083,998. Circuits employing non-linear capacitors. RADIO CORPORATION OF AMERICA. Nov. 5, 1964 [Dec. 4, 1963], No. 45135/64. Heading H3B. In order to prevent spurious blocking or unblocking of a transcharger by an associated alternating voltage two of the pulse operated ferro-electric elements, the source of the associated alternating voltage and the load to be energized thereby are connected in a bridge network. In the arrangement shown in Fig. 2 a balanced bridge is connected as shown in which electroluminescent elements EL1 and EL2 are energized by alternating voltage source 50 under the control of the transcharger comprising ferro-electric elements FE1, FE2 and FE3 of identical thickness. Two of the arms of the bridge are formed by halves of the source 50, the connection between the two halves being connected to ground through source 52. A positive reset pulse from source 52, Fig. 3a (not shown) polarises FE1 and FE2 in opposite directions and FE3 in the direction towards the X-pulse source so that source 50 is prevented from energizing elements EL1, EL2. When a negative-going half select pulse from 52 and a positive-going half select pulse from source 54 are applied to the circuit, Fig. 3b (not shown) the capacitors are discharged so that the reset cycle of the alternating voltage from source 50 sees a low impedance path through the unblocked capacitors and energizes elements EL1, EL2. Since terminal A is maintained at ground the opposite terminal C of the balanced bridge is always maintained at ground potential and hence also the voltage across electrodes of capacitor FE3. Thus there is no tendency for the source 50 to unblock the transoharger when in its blocked state due to the voltages developed along the unblocked paths EL1, FE1, FE3 and EL2, FE2, FE3. When the capacitors FE1, FE2 are unblocked spurious blocking of these capacitors through the path EL2, FE2, FE3 is prevented due to the balanced bridge arrangement. In a 2 x 2 array, Fig. 5 (not shown) the alternating voltage source is in the form of a number of centre tapped secondary transformer windings each tap being connected to earth through the Y pulse and reset pulse source. In Fig. 6 (not shown) one electroluminescent element EL2 is omitted and the alternating voltage source comprises a tapped transformer secondary arranged so that the circuit forms a balanced bridge. In Fig. 7 (not shown) a compensating impedance is employed when one of the elements EL is omitted. Fig. 8 is a five-element transcharger circuit.
