Title: Ultrasonic inspection method and apparatus
IPC: G01N29/24
Filed: 1971-04-19
Abstract: 1347356 Ultrasonic inspection devices; ultrasonic probes ELECTRONICS RESEARCH CO Ltd 19 April 1971 [18 April 1970] 26403/71 Headings H4D and H4J In an ultrasonic system for the continuous inspection of a moving object 15 (e.g. hot or cold steel plate), wherein ultrasonic signals are transmitted into and received from the object via two acoustic delay lines, one of which is a hollow cylindrical roller 14 containing acoustical coupling and cooling liquid 17, and the other of which, 13, is mounted on a fixed axial shaft 16 together with a transducer 12, the delay line materials and dimensions are selected in relation to those of the test object 15 such that t 2 >t 1 >t x , where t 2 , t 1 , t x  are respectively the ultrasonic propagation times through the delay lines 14, 13 and object 15. This provides a time margin allowing the various echo signals to be resolved even when the delay lines have become worn in use. The active face of transducer 12 may be plane or curved. The roller 14 radii are selected within limits defined by the transducer size and curvature and acoustic velocities in the delay lines such that the acoustic beam converges towards the line of contact of roller 14 with object 15 (mathematical details are given). The acoustic impedance of roller 14 is matched to that of object 15. Roller 14 may be of steel. A damping block 11 is provided for transducer 12. Echo signals deflect vertically the horizontal time-base of a cathode-ray tube display. Variation of flaw detection sensitivity due to shifting of the contact line between roller 14 and object 15 or to pressure changes at this contact may be compensated for by providing several transducers on delay line 13, having overlapping directivity characteristics, and rapidly and sequentially switching (electronically) between their inputs or outputs.

Title: Process of colour photography
IPC: G03C1/815
Filed: 1937-05-10
Abstract: 501,000. Colour photography; photographic developing processes. KODAK, Ltd. May 10, 1937, No. 26469/38. Convention date, May 9, 1936. Divided out of 500,826. [Class 98 (ii)] Relates to a process of producing colour developed reversed images in a three-layer photographic element whose upper layer is not specially colour sensitized and which contains colour sensitizers in the middle and bottom layers which are stable to photographic developing baths and to mild silver oxdizing baths. In one form the first latent images are developed to silver and the silver removed, then the reversed silver halide image in the middle layer is selectively made developable by exposure to coloured light and developed to colour, then the reversed silver halide image in the bottom layer is selectively made developable by exposure to coloured light from the back and developed to colour and finally the reversed silver halide image in the top layer is made developable by exposure to light and developed to colour. In another form the reversed silver halide image in the bottom layer is first selectively made developable by exposure to coloured light and developed to colour, then the reversed silver halide image in the middle layer is made developable by exposure to coloured light from the front and developed to colour and finally the reversed silver halide image in the top layer is made developable by exposure to light and developed to colour. In order to avoid the effect of local under-exposure in the lower layers, all the layers are first saturated with developing agent in high concentration and are then treated with weak alkali to effect development. Alternatively a concentrated developing solution is allowed to diffuse into all the layers at as low a temperature as it is possible to employ without alteration in composition of the solution and the development process started or accelerated by warming the layers to room. temperature or above. The residual silver halide may be converted in one or more layers to silver chloride, in a line state of subdivision as described in Specification 501,003. Suitable colour sensitizers are : (a) for extreme orangered and red, 4: 4<1>-dichloro-2 : 2<1> : 8-triethylthiacarbocyanine chloride ; (b) for red, 2 : 2<1>- dimethyl-8-ethyl-3 : 4 : 3<1> : 4<1>-dibenzthiacarbocyanine iodide; (c) for yellow-green, 2 : 1<1>- diethyl-3 : 4-benzthia-2<1>-cyanine iodide. Specifications 427,518, 427,520, 454,498, 454,499, and 454,622 also are referred to.

Abstract: 807,188. Stamping ; blank - punching. HUNTON Ltd. Aug. 26, 1957, No. 26891/57. Class 83 (4). Means for facilitating alignment of one component of a machine tool, such as the bolster B of a press tool, comprises a plurality of spring- loaded bolts 1 mounted in the bolster or other component in such a manner that they normally remain inoperative but are capable on release, of raising the bolster frame or component, to a position where it is supported by the bolts on the machine bed 10 through their springs 7, the bolts operating as feet to facilitate movements of the bolster frame to produce alignment. In an embodiment four spring-loaded bolts are accommodated in counter-bored holes 3 in the bolster frame. Their springs 7 have a larger size turn or turns at their lower ends, adjacent the domed bolt heads 8. The bolts are drawn up into the holes 3 by nuts 6. Alternatively, a bayonet fixing maintains them in the inoperative position. In operation, when a fresh die and punch have been fitted to the tool and the bolster hold-down bolts H have been slackened, the bolts 1 are released by unscrewing the nuts 6 so that the bolts act as legs allowing the bolster to be rocked in any direction until the punch and die are aligned. Finally, with the punch and die in engagement the holding-down bolts H are tightened up. Specification 647,213 is referred to.

Title: Hydrofining of middle distillate feed stock
IPC: F02B3/06
Filed: 1959-08-07
Abstract: In the desulphurization of two petroleum fractions, namely (1) a diesel oil boiling in the range 350-700 DEG F. and (2) a middle distillate boiling in the range 225-550 DEG F. (e.g. kerosene, jet fuel or hydrocarbon solvent), each fraction is catalytically hydrofined separately, the feedstream to each hydrofining operation being preheated by indirect heat exchange with the effluent from the other hydrofining operation.  Fraction (2) is hydrofined at 400-600 DEG F. and 75-400 p.s.i.g. pressure in the presence of hydrogen-containing gas separated from the effluent from the hydrofining of fraction (1), the initial heat exchange being sufficient to bring fraction (2) to the hydrofining temperature. Fraction (1) comes directly from a pipe still and, after the initial heat exchange, is heated further to bring it to the hydrofining temperature.  The effluent from the hydrofining of fraction (1) passes to a separator where hydrogen-containing gas is removed, and then to a stripper vessel where hydrogen sulphide and light naphtha are removed, the final hydrofined diesel oil product being substantially free from sulphur.  The effluent from the hydrofining of fraction (2) may also pass to a stripper vessel where light naphtha, hydrogen and hydrogen sulphide are removed, the final hydrofined middle distillate being likewise substantially free from sulphur.  Light naphtha from the stripper vessel employed in connection with fraction (2) may pass to the stripping vessel employed in connection with fraction (1). The catalyst employed in each hydrofining operation may comprise cobalt molybdate on alumina. Apparatus for carrying out the process is described.
