The substance having at least two alcoholic hydroxyl groups per molecule may have the formula in which n is a positive integer, r a positive integer of at least 2 and G is a nitrogen atom in which case r equals 3, a group NR<SP>2</SP> in which R<SP>2</SP> is hydrogen on a monovalent organic radical in which case r equals 2 or the residue containing at least two carbon atoms after removal of r active hydrogen atoms of an organic compound originally having at least r alcoholic and/or phenolic hydroxyl groups. Preferred monomeroapto carboxylic acids are 2-mercaptobutyric, #-mercapto undecylic, #-mercapto stearic, o-mercapto benzoic, thioglycollic, 2- mercapto propionic and 3-mercapto propionic acids, thiomalic, 4 - mercapto - 3,6 - endomethylenecyclohexane - 1,2 - dicarboxylic acid, 2- mercapto adipic acid, 2-mercapto sebacic acid and 2-mercaptopimelic acid.

Title: Method of and apparatus for analysing two dimensional patterns
IPC: G06T1/00
Filed: 1969-08-26
Abstract: 1326881 Photo-electric analysis of patterns SIRA INSTITUTE 12 Aug 1970 [26 Aug 1969 5 June 1970] 42500/69 and 27271/70 Heading G1A The pattern defined by the outer profile, or inner or surface features, of an object is analysed by deriving an electrical signal of the Fourier transform of radiation reflected (specular reflection, scattering or diffraction) and/or transmitted through the pattern and comparing it with a reference signal. The reference may be obtained simultaneously or be pre-recorded. In the arrangement of Fig.1, a laser or tungsten lamp 10 is used to illuminate slit 15. A radial grating (spatial filter) disc 11 is rotated across the light beam. When its axis 50 is fixed, only one spacial frequency is analysed. The axis 50 may be movable, e.g. rotatable, with respect to the main axis 51 to provide more spacial frequencies or a disc bearing several groups of spaced lines may be used. A phase reference signal may be obtained by sub-system 14, 16, 17. Lens 19 focuses light on the object O 1 . A detecting arrangement comprising an integrating sphere 21, slit 60 and photo-multiplier 22, may be positioned, as shown to receive reflected light, or on the other side of the object for transmitted light. To obtain a simultaneous reference signal a reference object O 2  may be monitored using reference detection arrangement 24, 25, 61. The objects may be moving in synchronism in directions X, Y. When multiple spatial frequencies are analysed by using a moving axis disc, the whole of object O 1  may be illuminated instead of a slit-shaped area across its width. The reference path may be omitted and the output 23 recorded on a pen recorder and compared with a pre-printed reference response. The reference and test signals may alternatively be recorded on magnetic tape or in a computer store. In the arrangement of Fig.2 (not shown), the spatial filter disc is positioned after slit 15. Alternatively it may be between the object and the detector.  Particular applications mentioned are analysis of patterns such as stamps, labels, drawings, printed circuits, micro circuits, photographs, C.R.T. displays, specimens, fingerprints, metal or plastics gear-wheels, cams &c. Lens examination is excluded in banknote validation, the notes are conveyed past a plurality of pattern monitoring units e.g. two, working at two respective spacial frequencies, monitoring by reflected light on one side of the banknote and two corresponding units on the other side, together with a unit operating by transmitted light, Fig.4 (not shown). Different spacial frequencies are used to detect different types of defects. The detectors may be provided with colour filters. Faulty banknotes are separated out. Analysis of patterns may be carried out using visible light or infrared, y- or X-radiation.

Abstract: 1339062 Electrode boiler MARSTON EXCELSIOR Ltd 24 April 1972 [26 Jan 1971] 3168/71 Heading H5H An electric flow heater comprises a plurality of spaced electrodes 25, 28 mounted against the inclined walls of the flow chamber and displaceable along the walls to alter the spacing between the electrodes 25, 28. The chamber is predominantly frusto-conical with an upper cylindrical portion. Three equi-spaced electrodes are mounted in the chamber and each comprises a polypropylene support 25 whose rear surface engaging the wall of the chamber is of frustoconical shape. The active area of each electrode is formed by a titanium sheet 28 bent to form two flat surfaces 26. The titanium sheet has a surface coating of iridium, rhodium, an alloy of iridium and platinum or an alloy of iridium, rhodium and platinum. Each electrode is connected to the supply by a stud 31 secured to sheet 28 and an insulated wire 30 which extends through a circumferential conduit 33 on the outside of the chamber casing. Each electrode 25, 28 is biased towards an outlet 17 by a spring 35 which also biases it against the wall of the chamber. The axial position of the electrodes 25, 28 is adjusted by a nut 19 screwed on to the outlet 17. Movement of the nut is transmitted to the electrodes by push rods 40 extending through the upper wall of the casing. In an alternative embodiment, (Fig. 6, not shown), a coil spring biases the electrodes away from the outlet and separate coil springs between adjacent electrodes biases them against the frusto-conical surface of the chamber. The adjusting nut is mounted on the inlet and acts on the electrodes by means of push rods.

The organic compound or mixture preferably consists of or includes an alkanol having between 1 and 6 carbon atoms, e.g. methanol, ethanol, propanol, isopropanol, butanol, sec. butyl alcohols. Small amounts of surfactants such as quaternary ammonium halides may be added to assist in reducing multi-crystal formation. The seed crystals so obtained may be used in continuous or batch processing either in initial crystallization from raw syrup or in refining. In the apparatus shown, a reactor vessel 10 with stirrer 13 is supplied with a sucrose and water solution and ethanol through lines 12, 15, and seed crystals are withdrawn through a line 16 and fed to a crystallizer 20 with stirrer 23. Sucrose syrup to be crystallized is fed through a line 14, and slurry withdrawn at 22 is passed through a particle classifier 26 which directs small crystals through a line 24 back to the crystallizer, and larger crystals, together with fresh feed syrup from a line 43, to a second crystallizer 30 the output from which is classified at 36 into small crystals which are recirculated through line 34 and larger crystals which are discharged at 38. Water vapour resulting from boiling is drawn off through vacuum connections 40, 41.
