Title: Pyrotechnical illuminating body with light emission
IPC: F42B4/28
Filed: 1970-12-03
Abstract: 1315723 Flares BOFORS AB 3 Dec 1970 [3 Dec 1969 23 Nov 1970] 57581/70 Heading F3A A flare for dropping from a rocket, projectile or bomb comprises in one embodiment an illuminating body divided into a plurality of component parts 8-11, Fig. 2, which, on dropping the flare, assume the inclined position shown and act as separate flares. The flare is supported by a parachute 2 or braking wings and, as it falls, the relative wind A sweeps the smoke and particles away through the gaps between the component parts 8-11 to provide an increased unobscured flame area 3a. Resilient means are used to urge the component parts into the inclined position. In another embodiment, Fig. 4, the illuminating body 13 is not divided into component parts as previously but instead is provided at its burning surface with a truncated pyramid 12. This creates a plurality of inclined flames 3 with an increased unobscured area as before. In another embodiment (Fig. 6a, not shown) a plurality of flaps (15) covering the burning face of the illuminating body are erected by springs when the flare is dropped and assume the shape of a truncated pyramid.

Abstract: 1357767 Vinylidene fluoride copolymers E I DU PONT DE NEMOURS & CO 14 Dec 1971 [14 Dec 1970 10 Nov 1971] 58045/71 Heading C3P A continuous process for the preparation of vinylidene fluoride copolymers comprises continuously feeding to a reaction zone vinylidene fluoride, at least one other fluorinated ethylenically unsaturated monomer having at least as many fluorine atoms as carbon atoms, an inorganic free radical initiator, water, and a chain transfer agent, the latter being fed to the reaction zone alternately at a high rate and at a low or zero rate for periods each of which are three times the average residence time in the reaction zone, causing the reaction mixture to polymerize, continuously removing the resulting copolymer and mixing it so as to give a uniform broad molecular weight distribution. The mixing process may be carried out with the copolymer latex or this may be dried before or during the mixing period. A stabilizer for the latex may be added to the reaction mixture in the reaction zone or immediately prior to mixing the copolymer. In examples vinylidene fluoride is copolymerized with hexafluoropropylene with or without tetrafluoroethylene; ammonium persulphate optionally with sodium sulphite is used as initiator, diethyl malonate is used as the chain transfer agent and the "low rate of feed" is zero, and in some examples sodium hydroxide is fed to the reaction zone as an emulsion stabilizer.

Title: Information transmission
IPC: H04L13/08
Filed: 1973-12-14
Abstract: 1445173 Data transmission; recoding TELEFONAKTIEBOLAGET L M ERICSSON 14 Dec 1973 [14 Dec 1972] 58160/73 Heading H4P In a method of preventing, in the transmission of N bit characters, e.g. telegraphic signals, certain unwanted characters occurring, e.g. carriage return, each character is divided into parts having N-n bits and new characters are formed by adding to the N-n bit parts, new n bits selected in such a manner that only permitted characters are formed. At the receiver a reverse process is carried out. The arrangement is particularly advantageous in say a teleprinter network where it is desired to prevent erroneous reception of function signals, e.g. figure shift. In the case of CCITT Alphabet No. 2, 4 bits of the first character have a prescribed bit added to re-form 5 bit characters; the original fifth bit forms the first bit of the next group together with 3 bits from the second character et seq. At the receiver the reverse operation is performed. Start-stop bits may be added before transmission and removed on reception. Message beginnings and endings may be sent without conversion. Incoming signals 8 pass through gates 11 controlled by counter 13 to 4 bit intermediate memory 12 which are fed out through gates 14 controlled by counter 16, stepping at 5/4 counter 13 rate with a dead period, both counters being driven by a clock generator 10. Memory 12 feeds a 4 bit register 15; according to the embodiment described the added bit is inserted at the end of each character and is a 1 when bit positions 1, 2, 4 are 1s hence AND gate 17 through inverter 23 and AND 22 sets flip-fllp 19 to "1" which is passed through AND 18 at appropriate time; for other combinations of bits flip-flop 19 is set to 0 through AND 21. At the receiver incoming bits are led to a 5 position shift register 30. Pulses from clock 24 coinciding with leading bit edges are applied to a 5 stage ring counter 25 which blocks AND 26 every fifth pulse, input pulses being displaced approximately a ¢ pulse position. AND 26 applies another five stage ring counter 27 which steps shift register 30 also receiving incoming data bits. As a shift is not performed on arrival of bits added at the transmitter these are not registered and the first bit of the next received character occupies the 5th position in register 30, after which the 5 bits are "dumped" parallelly through gates 29 to register 31 before arrival of next bit.  Variations are described in the Specification which envisages other character groupings and alphabets.

Patent GB-1147548-A (GB)
Title: Communication apparatus for communicating digital electric coded signals
IPC: H04L17/00
Filed: 1967-12-27
Abstract: 1,147,548. Data transmission systems. INTERNATIONAL BUSINESS MACHINES CORP 27 Dec., 1967 [30 Jan., 1967], No. 58600/67. Heading H4P. Digital data is transmitted in one or other of two modes, e.g. 8-bit code or 4-bit code, transmission in each mode being preceded by a control signal. The control signals consist of two parts, the first of which readies the receiver for control by the second. If the first part of a control signal is simulated by data at the transmitter input that part is repeated so that the receiver is switched from the state of readiness by the repeat. Transmitter.-Parallel-bit input data passes via gate 19 to buffer 16 which via gate 22 feeds register 14 connected to transmission channel 12. When transmission is to be changed from 8-bit code to 2 x 4-bit code (in which each 4-bit group represents a decimal number) a control signal consisting of two 8-bit parts DLE, STX is transmitted. Decoder 20 recognizes the 8-bit DLE and via gate 31 sets bi-stable 30 to 1. The following 8-bit character STX is then transmitted and decoder 20 sets bi-stable 38 to 1 via gate 36. This bi-stable indicates the mode of transmission (or reception). Bi-stable 30 is reset via inverter 46 and gates 47, 48. Subsequently 2 x 4-bit code is transmitted. If two 4-bit words identical to the 8-bit word DLE fortuitously occur, bi-stable 30 is again set to 1 and a pulse passes via gate 36 and inverter 28 to inhibit gate 22 so preventing read out of the word DLE from buffer 16. The pulse also passes via gate 34 to set bi-stable 23 to 1 and via gate 52 and inserts DLE in register 14 for transmission. When a DLE is transmitted a signal appears on line 25 which passes via gate 60 to register 14 which now transmits a second DLE. To revert to the original mode a pulse on line 40 from the input unit resets bi-stable 38 and a control signal DLE, ETX is passed to buffer 16 for transmission. The DLE does not cause repetition because bi-stable 38 is reset. Receiver.-Serial-bit data on line 10 passes via register 14 and gate 17 to buffer 16 which passes it to the output unit via gate 18. On reception of the control signal DLE, STX bi-stable 38 is set to 1 as indicated above. If subsequently a DLE is, received, decoder 20 sets bi-stable 30 via gate 31 and sets bi-stable 23 via gates 36, 56. Consequently gate 18 is inhibited and the DLE is not passed to the output unit. If the following word is ETX, indicating a change in mode, decoder 20 resets bi-stable 38 via gates 33, 44. If however the following word was another DLE a pulse on line 67 passes via gates 66, 48 to reset bi-stable 30, so enabling gate 18 which passes this DLE to the output unit.
