Abstract: Abstract Apparatus for transferring electrophotographic images Electrophotographic image transfer apparatus wherein a toner image on a previously uniformly charged and image-wise exposed photoconductor sheet, is transferred to a receptor sheet.  The exact parallellism between both sheets in the toner transfer zone is obtained by fitting one sheet onto a rotatable cylindrical member, fitting the other sheet to a flat supporting member that may move tangentially to the cylindrical member, arranging the flat member for balancing about a pivot, the axis of which runs parallel with the direction of displacement, providing two laterally spaced spacing members to control the gap between the photoconductor and the receptor sheet, and biasing the flat supporting member towards the cylindrical supporting member.   The apparatus is principally intended for producing large-size lithographic aluminium printing plates (Fig. 5).

Abstract: ABSTRACT Metals Recovery Various metals including cobalt nickel and copper can be recovered from a roasted ground ore or waste and particularly from tailings of a pyritic gold ore by leaching with sulphuric acid, oxidising the separated leach liquor, filtering and partially neutralising the liquor.  In an improved process, the oxidation is effected with peroxomonosulphuric acid and the neutralisation with a 60:40 to 40:60 mixture of calcium and sodium hydroxide/oxide.  By so doing, it is possible to minimise the number of process stages by elimination of either or both solid/liquid separations and to combine the leach and oxidation stage, or to improve the separation of metals from impurities.

Abstract: RADAR DETECTION AND SIGNAL PROCESSING CIRCUIT            ABSTRACT Radar  detection and signal processing circuits are  provided where,   following a  front  end  having  an  RF  and  local oscillator  mixer  to an I.F.,  which is then  further  mixed against  a signal from a swept frequency oscillator,  in  the presence  of a microwave frequency signal,  the output  of  a band  pass filter goes to a detector for frequency  modulated intermediate  frequency  signals, and that detector  has  at least  a  first  output signal that is fed to  two  pairs  of complementary  paired comparators,  the outputs of which  are set to  low and high  threshold levels.   The first pair  of complementary comparators has a low threshold  level  output which  is  examined by a microprocessor for the incidence  of detected low threshold signal in a number of spaced cells  --as  determined by a clock which divides the  detector  output into time cells of the sweep period of the swept  oscillator.          Signal  processing  is  provided  so that  the  incidence  of signals in a pair  of  spaced  cells over a given  number  of consecutive  sweeps  causes  an  alarm.    Likewise,  a  high threshold  output  is  examined so that the  incidence  of  a detected high threshold signal in a pair of spaced cells over a  different,  lower number of consecutive sweeps,  causes an alarm.  The  sensitivity of the circuit may adjust up or down according  to  the number of low threshold signals  that  are detected;  or  dynamically if too many low threshold  signals are detected in a small group of time cells.

Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus for displacing a line of track chain is disclosed which is employable for the purpose of disassemb-ling,  assembling or reassembling the chain.   A guide table for guiding movement of the chain is adapted to tilt only in the upward direction together with a pair of rails which are raised or lowered by actuating a first cylinder.  A trolley moves forward and backward in the space as defined by both the rails by actuating a second cylinder while it is guided along the rails.  The trolley is provided with an engagement rod which extends upwardly therefrom through a slot on the guide table to come in engagement to a bushing in the chain.          Forward displacing of the  chain is achieved by way of the steps of tilting up the guide table together with the rails by  actuating  the  first  cylinder,  displacing  the  trolley forward by a distance equal  to one pitch of the chain by actuating  the  first  cylinder,  lowering  the  rails  to  the lowermost  position  by  retracting  the  first  cylinder  and displacing the  trolley backward to the intital position by retracting the second cylinder.   A distance of displacement of the chain is adjustably determined by selectively determi-ning  the  position  of  two  stoppers  on  a stationary  screw spindle which is extended below the rails in parallel to the latter.   Each of the stoppers is adapted to abut against an abutment member fixedly secured to the bottom of the trolley.

Abstract: REED VALVE FOR REFRIGERATION COMPRESSOR                 ABSTRACT OF THE DISCLOSURE          A suction valve for a small refrigeration com-pressor is in the form of a thin sheet metal reed having a sealing portion adapted to make sealing contact with a valve seat around the suction port on a valve plate.  The valve reed is formed from a valve sheet by an outline defining cut so that the valve reed is integral with the sheet.  The valve reed has a reduced width neck portion and in this neck portion the material is plastically deformed along a bend line so that in a normal unstressed condition the sealing portion of the reed is spaced away from the valve seat by a slight distance and as soon as the piston starts on the compression stroke the fluid pressure forces the sealing portion into sealing engage-ment to prevent back-flow through the suction port.  When the piston starts the suction stroke, the biasing of the valve reed causes the sealing portion to move out of engagement with the valve seat before there is a substan-tial pressure differential across the suction valve.  The compressor also has a reed-type discharge valve in which the valve head is normally inclined to the valve seat while making contact with the seat only at one point at the side of the valve head.
