Title: Electrical encoding and decoding apparatus
IPC: H03M7/00
Filed: 1974-06-19
Abstract: 1462889 Bit encoding/decoding INTERNATIONAL BUSINESS MACHINES CORP 19 June 1974 [2 July 1973] 27148/74 Heading G4C [Also in Division H4] Circuits are described for encoding fixed length groups of bits (e.g. 8 bits) supplied in parallel into an electric signal having signal transitions between two levels at certain ones of a plurality of clock pulses defining, for each group of bits, a sequence of clock periods, the number of periods in a sequence being less than twice the number of bits in a group, such that the level transitions are spaced by at least two but not more than a predetermined larger number, e.g. seven, of clock periods, and such that no transition occurs at the clock pulse bounding a sequence of the clock periods (e.g. the first), there being means to cause a transition at the bounding clock pulse if no transition occurs at the adjacent clock pulses (i.e. the last in the preceding sequence and the second in the current sequence), and for decoding such encoded signals to reconstitute the original groups of bits. As described, each 8-bit group B0-B7 is divided into two sections of 5 and 3-bits and two sub-sequences of signals of 8 and 5 clock periods are produced, each sub-sequence beginning with a bounding clock pulse. The encoder includes a manual switch 301 which enables it to encode the 8-bit groups as a concatenation of the 5- and 3-bit representing signals with bounding transitions as appropriate, or 5-bit groups, the decoder having a clock with a variable eight and thirteen pulse cycle. Eight bit bytes, e.g. from a processor, may be arbitrarily divided into 5-bit groups, encoded as such, and recombined after decoding. In the encoder eight-bit bytes are loaded in a register which is connected to an encoding network of AND-gates, OR-gates, and latches which provides a 13-bit output. The thirteen outputs are serialized by clock pulses T1-T13, the one bits inducing, e.g. in a magnetic disc write head 101 or a transmission circuit 100, signal level transitions between two states. The first and ninth bits of the encoder output boundaries 1 and 2 are set at 1 only if the last output bit for the preceding byte and the second output bit for the current byte are 0 and if the eighth and tenth output bits for the current byte are 0 respectively to produce the correct bounding transitions. In the decoder the transitions are read from the magnetic disc or received and generate pulses which are clocked through respective ones of thirteen AND gates by a phase-locked clock to set the appropriate stages in a 13-bit staticizing register. The register thus contains the data in the same form as the encoder outputs and the data bits, excluding the bits corresponding to bounding transitions are decoded in a logic network, the resulting bits being loaded in an 8-bit register.

Title: Process for the production of porous carbon blocks
IPC: C04B35/532
Filed: 1963-07-11
Abstract: Porous carbon blocks are manufactured by mixing crushed coked vegetable matter, particularly sawdust or wood charcoal, with a finely crushed solid carbonaceous binder which is hard and brittle at normal temperatures and has a high softening point, shaping the mixture into blocks, heating the blocks to a temperature just in excess of the binder softening-point to bind the constituents, cooling the blocks, heating the blocks rapidly, i.e. at least 100 DEG C./hr. to a carbonization temperature of at least 850 DEG  C. and cooling the resultant porous blocks.  A liquid or gel binder may be added to the mix. The crushed coked vegetable matter is preferably obtained by coking at a temperature high enough to effect the greater part of its shrinkage, and comminuting the coke.  The porous carbon blocks are used as refractory bricks or for electrodes.

Title: A data transmission system
IPC: H04L1/18
Filed: 1965-06-30
Abstract: 1,108,047. Data transmission systems. TELEFUNKEN PATENTVERWERTUNCS G.m.b.H. 30 June, 1965 [2 July, 1964], No. 27713/65. Heading H4P. In a data transmission system in which errors are corrected by repetition, the number of bits transmitted between return signals is counted. After the detection at the transmitter of the absence of n consecutive correct-receptionindicating return signals the transmitter sends a repeat signal and then repeats data previously transmitted. At the transmitter signals from a data source are passed in blocks of parallel signals to a first shift register from which the blocks pass both to line and to a second register. Clock pulses controlling the registers pass to a counter. Each block received correctly results in a return signal. The counter is reset to zero by each return signal. If more than n consecutive return signals are absent further transmission ceases and the second register is connected to the first register. Clock pulses at greater than bit rate now step the counter to a value equal to the number of cells in the second register, this number being equal to the number of bits transmitted in the round transit time. The clock pulses return to bit rate and the first of these will read out from the second register to the first register the first bit to be repeated. Prior to this the first register is set to zero, so that a repeat signal block 0000 ... is transmitted, followed by the repeated data. After the repetition the second register is disconnected and transmission from the source proceeds as before. In an alternative embodiment the repeat of the faulty block is preceded by a repeat of the preceding correctly received block. At the receiver, the signals are checked for mutilation and the blocks are passed alternately to two stores where they are subject to a redundancy check. If no fault is detected a return signal is transmitted and the corresponding block passed to the receiver output and also back to the same store to act as a comparison block, in the event of repetition, with the repeated correct block preceding the repeated faulty block in order to identify the beginning of the repeated faulty block.

Abstract: 1,260,908. Magnetic storage arrangements. BURROUGHS CORP. 2 June, 1969, No. 27838/69. Heading H3B. In a word organized magnetic storage arrangement, Fig. 4, comprising a plurality of thin film storage arrays in each of several planes 40A-40D, the read conductors 41A-41D and the write conductors 42A-42D are transformer coupled to read and write amplifiers 48, 50 respectively, each read conductor in a plane being adjacent a write conductor but crossing from above to below the arrays in the balanced manner shown so that noise induced by writing is self cancelling. Only one read conductor and one write conductor per plane is shown in Fig. 4, and word drive conductors and selection matrices are omitted. Each read transformer 46A-46D has two secondaries, and a terminating resistance is included at transformer 46D to minimize reflections. Similarly write transformer 44D has a terminating resistance connected between its primary windings. The chain of series connected secondaries in the read circuit acts as a delay line, each delaying a secondary current by the time taken for the signal induced in the primary by this secondary current to pass along the read conductor and be reflected back to the primary. The read and write conductors are four terminal transmission lines, each with two terminals connected to a transformer and the remaining two terminals at the ends of the plane opposite the transformer connected through flexible matching terminations (not shown), adjustment of which allows the induced noise to be cancelled efficiently. In Fig. 6, the read transformers are coupled to a further transformer 64 and no matching resistor is employed.
