Filed: 1958-08-25
Abstract: The invention comprises the barium, calcium or strontium lakes of monoazo dyes of formula:  <FORM:0875871/IV(c)/1> wherein the nucleus a is free from further water-solubilizing groups and may be substituted by a halogen atom or an alkyl or alkoxy group and R is a phenylene or naphthylene residue linked in the 1 : 4-positions.  They are prepared by coupling a diazotized aniline- 2-sulphonic acid with a suitable 2 : 3-hydroxynaphthoic acid arylide and reacting the monoazo dye obtained with a water-soluble salt of barium, calcium or strontium.  The lakes are red and are used to colour polyvinyl chloride and stoving lacquers.  In an example the monoazo dye 1-amino- 4-chloro- 5-methylbenzene- 2-sulphonic acid --> 1-(21 : 31-hydroxynaphthoylamino)- benzene- 4-sulphoni acid is prepared and reacted in aqueous solution with barium chloride to give a yellowish red lake.  Further dyes and the barium lakes thereof are similarly prepared from the following components:-1-amino- 4-methyl- 5-chlorobenzene- 2-sulphonic acid, 1-aminobenzene- 2-sulphonic acid and 1-amino- 4-chloro- or -methyl-benzene- 2-sulphonic acid; 1-(21 : 31-hydroxynaphthoylamino)- naphthalene- 4-sulphonic acid. The barium lake of the dye 1-amino-4-methoxybenzene- 2-sulphonic acid -1- (21 : 31-hydroxynaphthoylamino)- benzene-2-sulphonic is precipitated in the presence of alumina as a substratum. Specifications 751,447 and 768,832 are referred to.

Title: Shape recognition apparatus
IPC: G06V10/20
Filed: 1965-06-28
Abstract: 1,077,564. Automatic pattern recognition. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 28, 1965 [July 8, 1964], No. 27239/65. Heading G4R. In apparatus for identifying shapes, the outline of a shape is followed to obtain vertical and horizontal displacement waveforms, these are converted to binary numbers representing successive directions and from these a train of binary numbers is produced representing successive changes in direction, ten of these numbers at equal steps round the periphery are entered into a shift register and recirculated for comparison with stored representations so as to eliminate the effects of orientation. The shape is traced three times, x and y waveforms being produced each time. The speed of movement round the periphery is constant so the time taken to return to the starting point is a measure of the length of the periphery. In the first trace this time is converted to a D.C. voltage which is used to control the frequency of a pulse generator (70, Figure not shown) so that it produces ten sampling pulses in each of the next two traces. The x and y signals are differentiated to obtain the corresponding speeds of movement and these are combined at (30) to obtain a signal (30a) representing the one of sixteen sectors of a circle which contains the tangent to the trace at each instant. The direction representation is converted in diode matrix (40) to a combination of four binary bits which signals are applied to a subtractor (50) directly and through fixed delays. The output (50a) from the subtractor represents in four bits and a sign bit, the change of direction during the period of the delays 60a-60d). These values are entered with the shift registers (60-64) under the control of the ten equally spaced shift pulses from circuit (70). The scan traces twice round the periphery of the shape so that the values in the shift registers recycle completely being compared in each position with stored values in circuits (100, 101 &c.). When a match is indicated, a corresponding latch (110, 111 &c.) is set and whenthe control circuitry (90) indicates that the third tracing is complete the latches are read out via And gates (116, 117 &c.) and then reset. If more than one identification signal is produced circuit (120) blocks the readout gates. Instead of circuits (100, 101 &c.) built to respond to predetermined patterns, the contents of the shift registers may be compared with corresponding reference signals read out from a store.

Abstract: 1,085,568. Sorting digital data. J. B. DE COURVILLE. June 30, 1965 [June 30, 1964], No. 27765/65. Addition to 1,012,390. Heading G4M. Data is recorded on an input tape 200 together with an address tag (identified by a hole in column 7), and an output tape 300 is to be punched with the tags in ascending order, each tag being followed by all the data associated with that tag on the input tape 200. A start signal at 522 resets buffer register 500 and the right-hand register of comparator 600, and subsequently enters the first tag from tape 200 into buffer 500 through gates 511- 516. In the first read cycle of tape 200, comparator 600 produces a permanent output on 602 since the addresses entered in its left-hand register are all greater than the zero stored in its right-hand register. Comparator 650 produces an output on 652 to enter a tag in buffer 500 whenever the tag then in 500 is greater than that being read from tape 200, so that at the end of the first read cycle, buffer 500 stores the smallest tag to be found on tape 200. The end-of-tape signal produced by gate 270 causes the smallest tag to be transferred from 500 to the righthand register of comparator 600 through gates 321-326, enables gates 140, 271-276 to operate punch 30 to record this tag on tape 300, and resets buffer 500. In the next read cycle, comparator 600 produces an output on 601 whenever a tag read from tape 200 is the same as that last recorded on tape 300, i.e. the smallest, and the associated data is fed to punch 30 via gates 281-286, gate 603 preventing the tag itself from being repeatedly recorded on tape 300. In the same read cycle, the next higher tag is entered in register 500, and at the end of this cycle, this tag is punched into tape 300 and the process repeated. Comparators, Fig. 2 (not shown). The tags are stored in left- and right-registers (61, 62). AND gate (6161) provides an output to OR gate (63) if the most significant digit in (61) is greater than that in (62). If the most significant digits are the same, (6162) or (6160) and (6164) enable the output gates of the next lower stage, i.e. (6153) for (61)>(62) and (6156) for (61) = (62). The remaining stages are similar.
