Title: Image transmission

Granted: 1987-01-21
Abstract: A method of transmission or storage of a television picture involves dividing it into a plurality of blocks, subjecting them individually to a two-dimensional unitary transformation, transmitting or storing the transform coefficients and reconstructing the original blocks by the use of the inverse transformation. To reduce the data rate, the zero sequency coefficient is omitted for most or all the blocks, and the mean levels of the reconstructed blocks are adjusted to reduce visible brightness changes between them. The adjustment may be made to reduce the means square differences between the elements in two blocks along the common boundary. The division into blocks may give common elements in two blocks along each inter-block boundary. If a picture transition coincides with a block division an indication of this may be sent so that differences between elements along the division are ignored.

Abstract: A coloured inorganic complex of titanium, stannous and zinc oxidesfor use in making pigments capable of imparting for example red, yellow or green colours to plastics, paints, glasses or ceramics without reliance on toxic moieties. A wider range of colours can be obtained if the complex is used in a pigment system comprising excess oxides of titanium and zinc or stannic tin. The complex is preferably made by adding an acidified aqueous solution of ions of the metals (eg as metal sulphates or metal halides) to alkali so as to precipitate the oxides or oxide precursor such as hydrated oxides which are then washed and fired at over 450 DEG C to form the complex. The colours obtained may be adjusted by the presence of traces of residual alkali metal moiety.

Title: Procedure and means for measuring with the aid of an x-ray tube the distribution of fillers or equivalent in a web
IPC: G01N23/16
Filed: 1983-11-30
Granted: 1989-03-15
Abstract: A procedure and means for non-destructive measuring of the distribution in the thickness direction of the filler and/or coating materials in paper or cardboard. Radiation (Ie) emitted by an x-ray tube (20) is used to excite in the material component to be examined, its characteristic x-ray radiation, the intensity of this radiation being observed. Measurements are made on both sides (11, 12) of the specimen (10). The contents of other filler components are also determined by x-ray absorption measurements, and the base weight of the paper e.g. by beta radiation absorption. Measurements of said characteristic radiation, elicited with constant energy x-ray radiation as well as absorption measurements of radiation obtained directly form the x-ray tube (20) and of radiation produced in transformation targets (21) are made in order to eliminate by calculation the disturbing interaction of the filler components. Alternatively, distribution measurements are made with the aid of characteristic radiation elicited with radiation from the x-ray tube (20) varying in a known manner during the measuring cycle (T) and by measuring its absorption followed by equivalent calculations.

Abstract: The invention relates to a method of transferring information between microcomputers in a decentralized process control system, particularly for telephone systems. To prevent contention for possession of the information transfer bus without the need for central equipment, a simple bus system consisting of a multiwire data bus and two single-wire control buses is proposed. Bus mastership is passed on after transmission, with the address of the next transmitter being determined by each microcomputer itself and forming part of each message. Bus mastership is determined by communication of the previous transmitter and by calculations performed by the microcomputer itself.

Granted: 1989-01-04
Abstract: For both recording and replay, a digital audio tape (14) is accelerated very rapidly by a motor servo (9), motor (8) and capstan (7) so that the tape speed overshoots nominal speed range before settling back to this range in an oscillatory manner. The digital samples are recorded and replayed via a head (15), a random access memory (16) and input/output electronics (19). During recording, the store (17) is precharged by starting to write in as soon as acceleration is initiated. Read-out to the tape is initiated as soon as the tape first reaches the nominal speed range. Uniformity of samples as recorded on the tape is preserved by clocking a read address generator (21) at a rate proportional to tape speed, signaled by a tachometer (7). The write address generator is clocked at the constant sampling rate. For replay the write address generator is clocked at the tape speed rate while the read address generator (21) is clocked at the constant sample rate. Write in and read out are both initiated when the tape speed first reaches the nominal range. The addresses provided by the generators (20 and 21) are compared by a comparator (22) which provides a reference signal to the servo (9) in an arrangement such as to adjust the tape speed always in the sense to maintain a constant degree of filling of the store (17).

Granted: 1987-04-01
Abstract: An improvement to a Viterbi-type decoder for decoding convolutional error-correcting codes whereby decisions regarding which predecessor state to a given state most probably corresponds to the best path terminating in that given state are stored in association with that given state and not in association with the best path. Paths are reconstructed by searching through such stored decisions. Such searches are used to recover a number, possibly greater than one of data symbols for later output from the decoder. The larger this number, the less frequently a search need be carried out.
