Patent GB-1461536-A (GB)
Title: Electro-optical
IPC: G01N21/88
Filed: 1974-04-25
Abstract: 1461536 Electro-optical gauging apparatus BAI CORP 25 April 1974 [27 June 1973] 18240/74 Heading G1A The dimensions of machined parts or other objects are checked or the objects graded in accordance with measurements performed by an electro-optical scanning arrangement which develops a video signal which is compared with stored reference values. A shadow image of the object 3 is projected via beam-splitting mirror 6 (or prism) on to the photosensitive face of an image dissector tube 11. The preamplified output is fed to a shaper amplifier, Fig. 2 (not shown) and used to control generation of clockpulses. Thus when during one line scan the image dissector tube beam encounters one edge of the object, the clock is started and when the beam reaches the other edge, the clock is stopped. The number of pulses, representing the width of the object at that line scan, is counted and compared with a number of stored reference levels to decide which grade the object is to be sorted into. A detail description of the comparison circuit is given with reference to Fig. 4 (not shown), and comprising a four-level comparator. The circuitry also includes facility for entering x- and yco-ordinates along which scans are to be performed, the angle at which the scan is made and the nominal dimension. Calibration. The beam-splitter 6 is provided so that source 1 can be switched off and source 20 switched on, to illuminate a reference grid for projection on to the scanner. The grid has a number of equi-spaced lines and is used to set up the scanning system so that it counts the correct number of clockpulses during a line scan. Calibration is in  general to correct for both optical and electrical non-linearities in the system. The grid is scanned and the video signal is fed both direct to a "correct count" register (40) Fig. 6 (not shown), which counts the number of actual crossings of grid lines and also to the circuit 7 Fig. 2 (not shown), to control the clockpulse generator and counter. If there is a discrepancy between the two counts, the sweep generator is adjusted so that the rate of scan is changed to null the difference. The grid is also provided with five square marks which are scanned and enable positional calibration of the scanning arrangement by adjustment of amplifiers in the circuit. Sub-routines. Modification of the shape of the scan path to suit measurement of particular objects is described; e.g. cylindrical bored members, whose internal and external diameters and circularity is to be measured, Figs. 8a-e (not shown); tooth-gear, Fig. 8f (not shown); a screw, for pitch diameter &c. Fig. 8g (not shown); radius or centre of curvature of cylindrical members, Fig. 9 (not shown). Optical modifications. When the internal diameters of a tube having an unsymmetrical bore configuration are to be measured, converging and diverging beams of light are required to allow this, Fig. 11 (not shown). Measurement of the thickness of a glass plate is carried out by measuring the distance between reflections from internal and external faces, Fig. 12 (not shown).

Patent GB-392763-A (GB)
Title: A process for the production of soap-like preparations, wetting, dispersing and penetrating agents and protective colloids
Filed: 1932-06-30
Abstract: Soap-like preparations, wetting, dispersing, and penetrating agents and protective colloids are manufactured by reacting heterocyclic bases with tertiary nitrogen atoms in the ring, e.g. pyridine, quinoline or isoquinoline or homologues or substitution products thereof, with mixtures of concentrated halogen hydracids and higher alcohols, i.e. those containing at least six carbon atoms in the molecule, or with sulphuric acid esters of such alcohols. Alternatively the higher alcohols are reacted with halogen hydracid pyridides, quinolinides or isoquinolinides or homologues or substitution products thereof.  In the case of mono-nuclear bases it is preferable to employ alcohols or sulphuric acid esters in which the alcoholic residues contain ten or more carbon atoms.  The pyridinium, quinolinium, and isoquinolinium salts are easily converted into salts of other acids, e.g. the chlorides on evaporation with nitric acid yield the nitrates.  They possess powerful dispersing properties in concentrated acids as well as in aqueous solutions.  The aqueous solutions of the pyridinium halides give with silver salts no precipitates but highly dispersed silver halogenide sols.  The wetting effects are particularly evident in the decyl pyridinium halides, the washing and dispersing effects in the cetyl and octadecyl pyridinium halides and sulphates.  In examples: (1) pyridine is reacted with cetyl alcohol and concentrated hydrobromic acid to produce cetyl pyridinium bromide; alternatively the alcohol is reacted with the halogen hydracid pyridide; (2) pyridine is reacted with a sulphuric acid ester of lauryl alcohol (formed in situ from chlorosulphonic acid and lauryl alcohol).  Other starting materials specified are picolines, aminopyridine, and methylisopropylquinoline.ALSO:As dispersing-agents and protective colloids may be employed quaternary salts derived from tertiary nitrogenous heterocyclic bases, e.g. pyridine, quinoline and isoquinoline, by the action of mixtures of concentrated halogen hydracids with alcohols containing at least six carbon atoms in the molecule, or of sulphuric acid esters of such alcohols.  In the case of the mono-nuclear bases the alcoholic residues should preferably contain ten or more carbon atoms.  The compounds possess powerful dispersing properties in concentrated acids as well as in aqueous solutions, these properties being most marked in the cetyl and octodecyl pyridinium halides and sulphates.  The aqueous solutions of pyridinium halides give with silver salts no precipitates but highly dispersed silver halogenide sols.

Abstract: 1330227 Polyurethane foam GENERAL TIRE & RUBBER CO 2 June 1971 [8 July 1970] 18680/71 Heading C3R A catalyst for use in the preparation of waterblown polyether polyurethane foams comprises: (I) an organotin compound, (II) a quaternary ammonium base and (III) an alkyl, aryl or aralkyl ester of an organic or inorganic acid which splits off its acid derived portion so as to neutralize II. III is defined in the broadest sense as the reaction product of an alcohol and acid and includes ethylene bis-chloroacetate, trichloroethyl phosphate, a chlorinated paraffin, a partially hydrolysed copolymer of vinyl chloride and vinyl acetate, polyvinyl chloride, hexachlorobenzene and methyl-p-toluene sulphonate. Preferred III are those derived from acids, the strongest of which, in a specific ester has, in an aqueous soln. at room temperature, a pK value for the first dissociation stage of <2. I may be stannous octoate and II may be tetramethylammonium hydroxide. A polyurethane may be prepared by reacting a polyether polyol, a polyisocyanate, water and the catalyst combination set out above. Use of this catalyst reduces the residual odour normally associated with polyurethanes prepared from organotin and quaternary ammonium base catalysts.
