Title: Method of retreading tyres and apparatus for use therein
IPC: B29D30/56
Filed: 1971-10-18
Abstract: 1389421 Retreading tyres KENTREDDER Ltd 17 Oct 1972 [18 Oct 1971] 48368/71 Heading B7C Retreading a worn tyre is effected by placing a pre-vulcanized tread band in a mould, spreading apart the beads of the tyre to reduce its external diameter sufficiently to permit insertion of the tyre within the tread band in the mould, positioning the tyre within the tread band, and releasing the beads so that the tyre contacts a bonding layer on the tread band. The bonding layer is vulcanized by the application'of heat. The tread band may be supplied to the retreader as a one-piece annulus, or may be cut by the retreader from a strip of prevulcanized material which is then united at its ends by vulcanizable bonding material, the ends may form a butt-joint or may be cut so as to interlock. Apparatus for effecting the retreading comprises a tyre bead spreader, a mould for receiving the tread band, and a heating ring (R), (Fig. 2, not shown), an inflatable bag (E) and a support ring (S) placed in use within the tyre. As illustrated in Fig. 3 the bead spreader comprises a fixed bead support and a movable bead support fast with the rod C of a ram B mounted on a support frame A. The mould M is supported at the pivoted connection of levers L1, L2, which are pivotally connected to the frame A and a link N fast with the rod C respectively. Retraction of the rod C will reduce the tyre beads spacing and simultaneously the mould is moved by levers L1, L2 to retain the tread band correctly positioned with respect to the worn tyre. In an alternative apparatus (Fig. 4, not shown) the bead supports are moved simultaneously relative to the mid-circumferential plane of the tyre, so that movement of the mould during the reduction of the bead space will be unnecessary. In each apparatus the mould is initially removed to permit a tyre to be placed on the spreader, and the external diameter of the mounted tyre is reduced before the mould with the tread band therein is restored to the position illustrated.

Title: Information transmission systems
IPC: H04L23/02
Filed: 1971-10-21
Abstract: 1353217 Multiplex systems INTERNATIONAL STANDARD ELECTRIC CORP 21 Oct 1971 [26 Oct 1970] 48952/71 Heading H4R  In a multiplex system each of a number of data signals is multiplied by a respective signal sequence, called a Paley function, which is a selected Walsh function needed to set up Hadamad matrix of rank 12. At the receiver the multiplexed signals are recovered using a similar set of Paley functions. As described the Paley functions are derived by a set of NAND gates connected to the output of a scale 12 counter, Fig. 11 (not shown) and the different functions, Fig. 3, are fed to multipliers MT, Fig. 4, to be modulated by the different data streams, each of which has a period during which it stays constant which is equal to the common repetition period of the set of Paley functions. The resulting signals are added in a summer and the multiplexed signal sampled by a pulse signal and the resulting variable amplitude pulse sequence is band limited in a 48-96 kHz filter. The 48 to 96 kHz band is modulated to a 60 to 108 kHz group frequency band to be added to similar groups to form a conventional super group. At the receiver the incoming signals are passed through a conventional filter and demodulated to restore it to the 48-96 kHz band to be sampled by a pulse signal TRI(12, 0). The output is held between samples to produce a step waveform which, by multiplication with the appropriate Paley functions in multipliers MR1-MR11 provides signals which, when integrated over the common repetition period of the Paley functions, provide the output signals 1 to 12.

Title: Zero code suppression in data transmission systems
IPC: H04L25/49
Filed: 1975-11-28
Abstract: 1515740 Data transmission WESTERN ELECTRIC CO Inc 28 Nov 1975 [2 Dec 1974] 48971/75 Heading H4P A zero code suppresion circuit comprises means for counting a stream of data bits into groups, means for forcing the last bit thereof to non-zero, and means responsive to a second non-zero bit in a group for resetting said means for counting to count the second non-zero bit as the first bit of a new group. As shown in timing diagram 4(a), a data stream is counted into groups of N bits the first group starting with a naturally occurring ONE pulse 31; if no other ONES occur in the following bit stream, ONE pulses such as 32, 33, 34 and 43 are forced into the stream at the end of the second and following groups. If, in any group, a ONE pulse is present, such as pulse 37 in diagram (b), then no ONE is forced into that group. If a second ONE is present, such as pulse 42 in diagram (c), then this pulse is counted as the first pulse in a new group of N bits and the foregoing rules again apply. Where the data stream contains forcing bits the arrangement is modified so that a ZERO previous to the forcing bit is forced to a ONE if the forcing bit is itself in a position liable to forcing. A suitable arrangement for effecting the required procedure includes a counter, a flip flop and associated logic circuitry and is described with reference to Fig. 3 (not shown). The arrangement is such that each group is guaranteed to contain a ONE, the size of the groups being effectively adjusted according to the data received thereby avoiding forcing ONES unnecessary to achieving a required pulse density sufficient to preserve timing information in the bit stream.

Abstract: 1318989 Making electro-erosion electrodes, rolling, planing GLANZSTOFF AG 15 Oct 1970 [18 Oct 1969] 49003/70 Headings B3A, B3L and B3M A method of making electrodes for producing profiled spinning bores by electro-erosion comprises rolling hard copper wire and trimming it to the required cross-sectional size and shape. A copper wire is subjected to a preliminary rolling to form it roughly to its finished shape and is then annealed. Rollers 5, 6, 7 mounted equi-angularly to each other are set by means of adjusting screws 4 to correspond accurately with the dimensions of the finished electrode. The part-formed electrode is then passed up to ten times between the rollers, which are rotated manually by a hand wheel 10 and bevel gears 8. When forming symmetrically profiled electrodes, it is preferred to turn the blank between each rolling operation. The rolled electrode is passed through slots 18 in a block 20 and a knife 19 trims each profile arm in turn. Different blocks are used to trim the arms in the case of asymmetrical electrodes, Figs. 2, 4 (not shown). The wire is preferably heated between each rolling operation. The preliminary rolling operation is performed when the minimum thickness of the profile arms is less than 40 Ám.

Abstract: 1474127 Recognizing pulse sequences TELEFONAKTIEBOLAGET L M ERICSSON 18 Nov 1974 [22 Nov 1973] 49890/74 Heading G4H An arrangement for recognizing in a received signal a certain pattern of N pulses (N greater than 2) distributed in time in a given manner, comprises a pulse source for the local production of the pattern, N time measuring circuits started by the N local pulses respectively, and comparison means fed from the time measuring circuits, via respective memories in N-1 cases. In Fig. 1, an input sequence of selectivelytimed pulses at 11, after shaping at 12, starts a generator 13 which produces the reference sequence to be recognized (this sequence being one of a number, selected at 14). Each pulse of the reference seqeuce is produced on a respective line from 13 and starts a respective one of (7-bit) binary counters 15, 16 ... 17 counting clock pulses from 19. A memory 25, 26 . . . and comparator 35, 36 ... are associated with each counter except 17. Each input pulse from 12 causes the 3 least significant bits from each counter (except 17) to be stored at an address specified by the 4 most significant bits from the counter in the corresponding memory, and also causes the contents of the address in each memory specified by the 4 most significant bits from counter 17 to be compared with the 3 least significant bits from counter 17, a recognition output being produced from an AND 41 if all the comparisons indicate equality together. Interference pulses merely result in all the counts being too big by the same amount (as by premature starting of the generator 13) and/or produce redundant entries in the memories 25, 26 ... ,Fig. 5 (not shown), shows a more detailed implementation in which (a) the generator 13 produces its outputs by decoding a count of "equality" pulses from comparison of counter 15 (started from 11) and a series of numbers obtained from a read-only memory addressed by a count of the "equality" pulses, (b) delays are provided in the connection from 13 to 17 and in the connections from 11 to the memories and comparators mentioned above in connection with Fig. 1, to provide tolerances on pulse timing. The counters can be replaced by integrators (ramp generators) and the memories by capacitive holding circuits, for analogue operation.
