Title: Improvements relating to the detection of flaws in dense materials
Inventor: METCALF ARNOLD
IPC: G01N23/09
Filed: 1964-07-13
Abstract: 1,113,594. Testing by irradiation; local viewing using point-by-point analysis. PLESSEY-UK Ltd. 16 July, 1965 [13 July, 1964], No. 28804/64. Headings H4F and H5R. [Also in Division G1] Flaws and/or certain impurities in dense material are detected by subjecting the material to neutrons and detecting such neutrons as they emerge from the material by means of a directional neutron detector. Such detector comprises a multiplicity of scintillator elements embedded in hydrogenous material and located along the paths of neutrons which pass directly through the material. The scintillator elements respond by the emission of light impulses when neutrons impinge on them and the intensity of such light impulses is significantly greater if neutrons travel along the elements rather than impinge on them at an angle. A neutron generator 1 has its target 2 located adjacent a steel test-piece 3, behind which is a directional neutron detector 4. Neutrons passing straight through the piece 3 without deflection by flaws and/or impurities produce a higher light emission than neutrons deflected or scattered by flaws and/or impurities in the piece 3 and which impinge on the scintillator elements at an angle. Light emitted is conveyed by light guides 5 to an image intensifier 6. The image is viewed on a fluorescent screen, through binoculars, a binocular microscope or camera apparatus. Detector 4 and light guides 5 are as free as is practicable from oxygen. In an anticoincidence arrangement (not shown) the light guides 5 are terminated on one or more photomultipliers with which are associated electrical coincidence gates which prevent simultaneous pulses from being part of the final flow pattern. which may be displayed on a cathode-ray tube. A photo-multiplier may scan the light guides or vice versa. The test-piece 3 may be moved between the generator 1 and detector 4.

Title: Process for the preparation of vanillin and i-vanillin
IPC: C07C47/58
Filed: 1926-11-16
Abstract: 285,551. Boedecker, F. Nov. 16, 1926. Addition to 285,156. Vanillin and isovanillin are obtained from safrol by heating with an alcoholic alkali to obtain the m@- and p-propenylpyrocatechin-monomethoxymethyl ethers, which are separated by fractional crystallization of their sodium salts and are worked up separately into the two isomeric propenylpyrocatechinmethyl ethers or the aldehydes or almost completely into one of them. In an example safrol is heated with methyl alcoholic potash in an autoclave and the product is transformed into the sodium salts and the methoxvisoeugenol allowed to crystallize out. The benzoate is described. The methoxy-isochavibetol salt is left in solution, and these derivatives are converted into vanillin or isovanillin by the method described in the parent Specification. The sodium salts dissolved in the mother liquor can be methylated and by treatment with acids converted into isoeugenol and thence to vanillin. The methoxy-isoeugenol may be converted into isoeugenol or vanillin by forming the benzoyl compound and heating with acids to obtain 4- acidyl-1-propenyl-3 : 4-pyrocatechin, methylating and saponifying, or it may be converted into the benzyl ether by means of benzyl chloride, the methoxymethyl group is then saponified and methylated to obtain the 4-benzyl-3-methyl ether which is oxidized to the corresponding aldehyde and on heating with acids yields vanillin. The benzyl ether of the propenylpyrocatechin can also be oxidized directly and the aldehyde obtained converted into vanillin by methylation and treatment with acids. In this method, unless ozone is used, it is necessary to fix the phenolic hydroxyl intermediately by an acidyl radicle, which is removed again prior to methylation. Or the oxidation may be carried out at once after benzylation and the 4-benzylprotocatechuic aldehyde produced after treatment with acids, gives on methylation 4 - benzyl - 3 - methylprotocatechuic aldehyde from which the benzyl group can be split off.

Abstract: 1354567 Vibrators DYNAPAC MASKIN AB 24 June 1971 [23 June 1970] 29622/71 Heading F2X A vibrator driven by a pressurized fluid medium, e.g. compressed air, flowing between a hollow cylinder 2 and the bore 19 of a housing 1 in which the cylinder is mounted for relative rotation, comprises five longitudinal spiral grooves 3a equispaced circumferentially about the bore 19 and four longitudinal spiral lobes 5 equispaced circumferentially about the cylinder 2, the dimensions of the cylinder 2, lobes 5, bore 19 and grooves 3a being such that relative rotation may be effected between the cylinder 2 and the bore 19 whereupon successive lobes 5 engage in successive grooves 3a, the spiral grooves 3a and spiral lobes 5 forming part of the flow path for the compressed air. The compressed air enters the vibrator through a hose 10 and hose coupling 9, and flows down a central passage 8 in the cylinder 2, returning along the space between the cylinder 2 and the bore 19 of the housing 1. The bore 19 is defined by a cylindrical insert in the housing 1 comprising at least cylindrical bushings 4, 4<SP>1</SP>, 411, axially aligned and having the longitudinal grooves 3a formed in their inner surfaces, located between two plain bore bushings 7, 7<SP>1</SP>. The end portions 6, 6<SP>1</SP>, of the hollow cylinder 2 are plain and engageable in rolling contact with the plain bore bushings 7, 7<SP>1</SP>. The diameter of a circle contacting the outer tips of the lobes 5 is substantially equal to, but not greater than, the diameter of the bore into which the spiral grooves 3a are formed plus the depth of one longitudinal groove 3a. The spiral grooves 3a and the spiral lobes 5 comprise multi-start screw threads. The returning compressed air flows between the grooves 3a and the lobes 5 and torque is thus applied to the cylinder 2 to produce a vibrationgenerating rolling motion of the cylinder 2. Owing to the number of longitudinal grooves 3a exceeding the number of lobes 5 by one, a space is created opposite the lobe engaged in a groove having the shape of a spiral loop around the cylinder 2 and this space will move circumferentially as a result of the rolling movement of the rotor.

Abstract: 935,586. Welding by fusion. BRITISH OXYGEN CO. Ltd. Sept. 15, 1959 [Sept. 17, 1958], No. 29822/58. Class 83 (4). Arc-welding apparatus is arranged to operate automatically to weld together abutting parts having gaps between the sections to be welded. As shown, the workpiece consists of a beam cut along its web to form two castellated sections 105, 106 which have been displaced to bring the prominences 107 on each opposite each other. It is required to weld the portions 107 together and for this purpose a welding head 100 is used movable along the line 109 and supported by carriage 101. The head carries two photo-electric sensing devices 120 giving signals according to whether they are passing over the workpiece or not. Movement of the carriage is effected by two electric motors coupled through clutches and brakes to a differential from which the drive is taken. If the apparatus is started with the head in a position such that neither device 120 is over the beam, one motor will be disconnected and the other will drive the carriage at high speed until the forward device 120 detects the beam. The second motor is then connected to give a slowspeed drive until the second device 120 reaches the beam. The head is then stopped for a short period and circuits completed to establish the welding arc and feed the welding electrode. As soon as this has been done progress at slow (welding) speed is continued. When the forward device 120 clears the beam a second short pause occurs to allow for crater filling at the end of the weld. The welding current and electrode feed are then stopped and fast travel restarted. A manual control enables either direction of travel to be chosen. The relay circuits are described with reference to Figs. 4 and 5 (both not shown).
