Abstract: US                            ABSTRACT      A method for purifying crude argon containing argon, oxygen and nitrogen comprises the steps of reducing the amount of nitrogen in the crude argon to between a trace and 0.15%  (by volume) and passing the remaining oxygen and argon, together with residual nitrogen, through 4A molecular sieve to separate the oxygen and argon.  The 4A molecular sieve is particularly effective if steps are taken to ensure that all the remaining oxygen and nitrogen has to pass through a volume of 4A molecular sieve which is wholly at or below -250°F.

Abstract: OPTICAL READ-WRITE SYSTEM WITH ELECTRONICALLY VARIABLE IMAGE SIZE            Abstract of the Disclosure Disclosed is an optical read-write system including a first laser scanner for linearly scanning an object and generating a digital signal for the line scan.  The digital signal is stored in a buffer at a read clock rate which is correlated to the scan of the first laser scan-ner.  The digital signal is read-out of the buffer at a write clock rate and is applied as a control signal for a second laser scanner which linearly scans an image plane to develop an image.  The second scanner scans at the same scan rate and distance as the first scanner, and the size of the image compared to the object size is determined by the differential of the read clock rate and the write clock rate.

Abstract: ABSTRACT             A method of Gasifying an Ash-Containing Fuel in a Fluidized Bed A method of gasifying an ash-containing fuel in a single fluidized conversion bed in which the fuel is passed into a lower region of a bottom zone of the bed wherein the fuel is at least partially gasified at a temperature below the ash-softening point.  The resulting fuel and ash are of a sufficiently small size and/or weight to pass from the bottom zone to a top zone of the bed wherein the temperature is above the ash-softening point whereby unconsumed fuel is at least partially combusted and ash particles stick to each other and/or to solids in the top zone of the bed until the particle size and/or weight of the resul-ting agglomerates causes them to sink to the bottom of the bed from where they can he removed.  The bottom zone may contain CaO-comprising particles to fix labile sulfur.  The hot combustible gases leaving the top of the bed have a reduced burden of entrained ash and may be cooled, e.g. by admixture with cool flue gas to prevent entrained ash adhering to downstream equipment through which the gases pass.

Abstract: Abstract A mechanical, seismic-shock-absorbing snubber adapted to accept extremely high impact loads that may be imposed upon it by reason of its interposition between heavy, relatively moveable structures.  While permitting essentially unrestricted, slow, relative motion between the structures, such as may be caused by thermal effects (e.g., the expansion or contraction of a high pressure steam pipe yieldably attached by way of hangers or supports to a building structure as in a nuclear power plant), the snubber limits both the velocity and acceleration of relative motion between the structures such as might result from violent seismic shock or vibration.  The snubber employs, as its damping mechanism, escapement means, preferably in the form of an escapement wheel, which rotates in response to relative movement of the structures between which the snubber is interposed and employs a cooperating, pivoted, engagement means, preferably in the form of a pallet member of predetermined effective mass driven by the escapement wheel into oscillation. It is the oscillation of the pallet member, the rate of which is limited by the pallet member's mass and natural period of oscillation, that restricts or damps the velocity and acceleration of relative motion between the structures with which the snubber is associated.  Alternatively, instead of employing an escapement wheel, a rack may be employed, with the teeth of the rack engaging hooks or pallets on the pallet member to drive the latter into oscillation as the rack is moved relative to the pallet member.

Abstract: BLOWER SYSTEM FOR AN AXIAL FLOW  ROTARY COMBINE CLEANING SHOE               Abstract of the Disclosure A self-propelled axial flow rotary combine includes a gen-erally fore-and-aft disposed separator including a separating rotor surrounded by a cylindrical grate.  A forward-mounted header gathers crop material from a field and feeds it to the space between the rotor and the grate for threshing and separa-tion, straw being ejected from the rear of the separator and a portion of the crop material, including grain and chaff, passing through the grate and generally downwards to be intercepted by either a reciprocating grain pan under a forward portion of the separator or a reciprocating cleaning shoe immediately rearward of the grain pan and beneath a rearward portion of the separator.          The grain pan is shaped so as to compensate for the laterally uneven distribution of the crop material as it passes downwards from the grate so that delivery of material from the rearward edge of the grain pan to the cleaner is distributed more uniformly across the width of the cleaner.  Beneath the grain pan and forward of the cleaner is a blower assembly including four indivi-dually housed centrifugal blower wheels, each scrolled housing permitting axial flow of air into each wheel from both sides and centrifugal delivery over substantially the entire periphery of each wheel.  The fan housings and ducts are arranged so that a portion of the air delivered by each blower wheel is delivered almost directly rearwardly and upwardly to the cleaning shoe while the remaining air portion is directed horizontally forward into a duct system extending across the width of the separator body and provided with deflectors for reversing the air flow so that it passes rearwardly above the grain pan and beneath and alongside the separator grate.  The larger radius and greater depth of opposite reversing outer air flow deflectors compared with a center deflector results in an air flow pattern with respect to the grate having an inner shallower portion and outer portions of greater vertical extent.

Abstract: ABSTRACT A main memory of a process control computer especially for controlling industrial machinery and plants is directly connected to a data input/output unit and via a separate address processor to an address memory.  A clock generator is connected to a program memory and the address memory and supplies sequential clock pulses for the execution of the program and for the simul-taneous delivery of addresses in each program step.  The main memory which stores the data from the data input/output unit after the feeding of the addresses from the address processor, supplies the data for the program step to an arithmetic logic unit, which simultaneously receives pulse-frequency driven operation commands from the program memory and feeds the operation results to the data input/output unit and/or to the main memory for storing. A program step counter connected to the program memory continues switching the program steps and controls the output of the operation commands from the program memory.  The data bus of the computer is separated from the address bus thereof.
