Abstract: ABSTRACT;            This test system is intended to test subscriber line interface circuits which are connected by means of one end to subscriber lines and by means of the other end are put in connection with a test apparatus. Change-over means are provided to disconnect each interface circuit from its subscriber line and to connect it to a test bus which is common to one group of interface circuits. Con-trol means are provided in the test apparatus for connect-ing, depending on the test to be effected, one interface circuit or two interface circuits to the test bus. This test system allows remote testing of interface circuits, for example from a telephone exchange by using only the normally existing links between this exchange and the interface circuits. This system is used in telephone communication networks.

Abstract: PROCESS FOR UPGRADING A HEAVY VISCOUS HYDROCARBON          Abstract of the Disclosure A process for upgrading a heavy viscous hydrocarbon, for example, ren-dering a heavy viscous crude pipelinable,  includes visbreaking, dis-tillation and solvent extraction steps.  A heavy viscous hydrocarbon is fed through the visbreaker which forms a feed to the distillation step.  A heavier fraction from distillation is fed to a solvent ex-traction  unit which  produces  a  fraction  which  contains  resin.  At least a portion of the resin containing fraction separated in the sol-vent extraction unit is recycled and combined with the feed which is to be subject to visbreaking so that  the total  yield  of products, residual and gas-free, is increased.  The recycled resin reduces the tendency of the asphaltenes to separate from the oil and thereby re-duces the tendency to lay down coke in the visbreaker;  this allows higher conversion to upgraded liquid products.

Abstract: DIGITALLY CONTROLLED X-RAY BEAM ATTENUATION METHOD END APPARATUS                      ABSTRACT   X-ray compensation masks (51) are prepared by exposing an X-ray target object (43), such as a patient, to a first beam of X-rays.  The X-ray fluence from the patient is received by an electronic image receptor (44) which provides an output signal indicating the intensity of the X-rays at all positions in the image field.  The image information is converted by an image processor (47) to transformed X-ray intensity values for a plurality of pixels which cover the image field,  A mask generating controller (48) determines the minimum transformed intensity value for any pixel, assigns to each pixel an attenuation number which is proportional to the difference between the transformed intensity value for the pixel and the minimum transformed intensity value, and issues control signals to a mask former (49) which deposits on a non-attenuating substrate (50) attenuating masses in a two dimensional array of pixels with the mass thickness in each pixel proportional to the attenuation number.  When the mask (51) is inserted into the beam from the X-ray source (41), and a second exposure taken, the X-ray fluency passing through both the attenuating mask (51) and the patient (43) will be substantially equalized across the image field.
