Patent SE-7903311-L (SE)
Inventor: STENBERG JOHAN EMANUEL
IPC: G01N21/21
Filed: 1979-04-17
Abstract: In a method and apparatus for studying surface properties of a testpiece, such as refractive index or thickness of a layer or film on said surface, electromagnetic radiation is directed on to the test surface or a reference surface which has known properties, and reflected on to the other surface. The angle of incidence in respect of the incident radiation, in relation to the respective surfaces, are the same, and the surfaces are so arranged that when the radiation is reflected from one surface on to the other, the parallel polarization component of the first reflection is the perpendicular component of the second reflection. Radiation in the same state of polarization as before the first reflection is extinguished by an analyzer, providing for point-to-point comparison between the two surfaces.

Abstract: A method is provided for treating the weld area of a welded ferritic stainless steel article to increase the resistance to intergranular corrosion. This method comprises the step of grinding the torch side surface of the welded article at a substantially uniform depth along the length of the weld after the material has solidified in the weld area, with the cross sectional dimension of the grind extending beyond the weld-base metal interface on both sides of the weld area. In accordance with this method, the depth of grind is uniformly controlled within the range of from at least 0.0005 inch as measured at the weld-base metal interface to less than 10% of the unground article thickness.

Abstract: The invention relates to an apparatus for reading a disc-shaped record carrier with a spiral information track in which an optically readable digitally coded information signal is recorded with a spatial bit frequency which is independent of the radius of the track turn. The scanning speed of the information track is selected to be a factor n higher than the scanning speed normally employed of the reproduction for the recorded information. By means of a memory device, information blocks being read and comprising a fixed number of data bits are time-expanded to restore the customary time relationship. A control unit determines the read-in cycles of the memory device for the storage of the information blocks being read and, via the radial positioning system for the read spot, it determines the scanning pattern of the record carrier so that the ultimately recorded information blocks are reproduced in the same sequence and at the desired rate.
