Abstract: ABSTRACT OF THE DISCLOSURE         A camera flash photographing control device having a signal conversion element which generates step wave voltage for which a signal level is gradually varied as time passes, by the operation of a counter which receives a pulse signal.  A signal conversion element is operated as an A-D converter in which digital signal output which corresponds to a required signal level is obtained by converting both analogue signals of luminance information of an object and iris information of a photographing lens  into said required signal level at the time of light measurement before shutter release.  A signal con-version element is operated as a digital-analogue converter in which analogue signal output which corresponds to a pulse sig-nal is obtained by converting the digital signal input of film sensitivity information into a required pulse signal at the time of shutter control after shutter release.  Digital signal output from a signal conversion element is stored in memory as camera photographing information at the time of shutter control and analogue signal output from a signal conversion element is sent as information on the degree of flash light emission at the time of shutter control.

Abstract: ABSTRACT OF THE INVENTION A differential protective relay for protecting devices on an ac electrical power system.  The protected devices  can  include  a  transformer,  a  generator,  or  a station bus.  The differential protective relay evaluates the current flowing into and out of the protected device only during the period when the current transformers are not  saturated.  The  differential  protective  relay  also detects internal faults accompanying external faults by evaluating the ratio between the current flowing into and out of the protective device.  When this ratio exceeds a predetermined  limit  the protective  relay  evaluates  the difference between the current flowing into and out of the device to determine if this  difference  is  sufficiently large  to  trip  the  relay.   When  a  current  transformer associated  with  the  differential protective  relay  is saturated,  the differential protective resay produces a restraint signal to restrain tripping.

Abstract: ABSTRACT     A process for high hydroconversion of heavy hydrocarbon liquid  feedstocks  such  as  petroleum residua containing at least about 50 V % material boiling above 975°F to produce lower boiling hydrocarbon liquid and gas products, wherein heavy RCR materials and metals compounds are removed in-situ from the reactor effluent liquid by solvent vapor extraction using a process-derived solvent vapor at supercritical con-ditions.  In  the  process,  the  feedstock  is  catalytically hydroconverted at 780-a60°F temperature,  and the resulting liquid fraction is contacted with a process-derived solvent vapor  fraction  having a  normal  boiling  range of 250-400°F and  heated  to  supercritical  temperature  to  dissolve  and extract substantially all  the hydrocarbon liquid fractions, and separate heavy RCR materials and the metals compounds contained  therein.    The  resulting  supercritical  solvent vapor with dissolved liquid fraction is pressure-reduced and distilled to recover the needed solvent fraction and to pro-vide a hydrocarbon liquid fraction product.  The hydrogena-tion step preferably uses an ebullated catalytic bed.  Also, if desired, the supercritical  solvent vapor extraction step can be used intermediate two hydroconversion reaction zones connected  in  series  to  product  additional  desired  lower boiling desulfuized hydrocarbon liquid fraction products.

Abstract: ABSTRACT     A mobile sewer and catch basin cleaning vehicle dislodges and removes debris in a conventional manner.  The dislodged debris is then conveyed into a debris compartment where it undergoes a two-stage filtration process.  The first stage removes the coarser debris from the reclaimed contami-nated water.  The second stage filters out the finer particu-late debris by drawing such water through a finely filtered media surrounding a rotating drum.  This filtered reclaimed water is then re-used in the cleaning operations.  The extremely fine filtration media is continually cleaned by small amounts of clean water being applied at high pressure through nozzles designed to spray the entire media area as the drum rotates.
