Title: Improvements in or relating to the manufacture of cast type bars
IPC: B41B11/00
Filed: 1932-09-23
Abstract: 407,727. Type-bar-making machines. LINOTYPE MACHINERY, Ltd., 9, Kingsway, London, and CEUPPENS, M., 34, Rue Joseph Coosemans, Brussels. Sept. 23, 1932, No. 26464. [Class 100 (iii).] Matrices.-In typebar-making machines adapted to produce slugs with type characters overhanging the slug bodies, those matrices which are used for casting characters having no ascenders are modified in that the recess which is provided with the character-forming surface is widened at the side adjacent the top of the character so as to produce a metal fillet which extends more or less across the top of the slug and unites the overhanging and body portions of the slug. The formative cavity 3 of the matrix 1, Fig. 8, for producing an overhung slug is offset relatively to the mould slot 4 but in order to avoid a weakness at the junction of the parts 5, 5<a>, Fig. 6, of the resulting slug, when the matrices are for non-ascender characters, the wall of the recess 3 of such matrices is splayed outwards as shown at 6 so that the slug produced will have its non-ascender characters united to the body 5 by a fillet of metal 5<c>.

Filed: 1974-06-19
Abstract: 1464016 Character recognition systems INSTITUTTET FOR PRODUKTUDVIKLING 19 June 1974 [25 June 1973] 27280/74 Heading G4R An optical arrangement for extracting features from a character to be recognized includes a number of optical channels each of which includes an optical device which has a unidirectional power of resolution and which is such that if it were subdivided in one direction, the subdivided parts would have the same optical characteristics as the complete device, e.g. a cylindrical lens. The devices are arranged with differently oriented directions of resolution so that each resolves clearly only those features of the character that are parallel to its orientation. In Fig. 4 there are four channels, each containing a cylindrical lens 20 oriented as shown. When a character, e.g. 2, at object plane 23 is viewed those portions that are parallel to the resolution direction of a lens appear sharply on image plane 21, the remaining portions being blurred as indicated. The features at image planes 21 may be detected by a matrix of photocells if the character is stationary. If the character is moved horizontally they may be detected by a column of photocells 18 at each image plane, or if the character image is additionally oscillated vertically by an oscillating mirror they may be detected by a single photocell at each image plane. In a modification two of the channels may have cylindrical lenses oriented in the same direction but having different powers of magnification. The lower power channel will provide sharp images of all portions of the character that are parallel to the resolution direction, whereas the higher power channel will provide sharp images only of those portions which exceed a certain length.

Title: Error correcting method for data transmission systems
IPC: H04L25/49
Filed: 1977-06-27
Abstract: 1536434 Data transmission; coding to reduce errors BRITISH AIRCRAFT CORP Ltd 27 June 1977 [30 June 1976] 27348/76 Heading H4P In a method of and apparatus for coding and decoding a binary input data signal for transmission, errors arising during transmission of the coded signal are automatically corrected during decoding. In the coding operation the data signal is resolved into groups of component transitions, each group being represented by a predetermined sequence of carrier signal modulation levels spanning several data characters, coincident modulation levels being summed so that each modulation level in the transmitted signal is determined by several neighbouring data characters. In the decoding operation the received signal is sampled at intervals of one data character, each sample being longer than a modulation sequence. Presuming that the sample contains up to a maximum number of errors, all possible corresponding data signals are reproduced and correlated to corresponding data characters in the data signals to determine the probable correct value of each data character. In the embodiment, incoming data signals are recoded to multi-level signals, e.g. 4 levels, each level corresponding to one phase of a 4-phase PSK system. On reception, decoded signals are placed successively and cyclically in a series of shift registers holding 2 bits additional to each word and by a series of comparisons, most likely errors are eliminated until preferably only one possible correct word remains. Logical arrangements for performing the various operations are described in the Specification.
