Abstract: Abstract of the Disclosure Improved gas-fired radiant heater has porous re-fractory panel mounted by its edges on a support to define a gaseous combustion mixture plenum from which the mixture flows through the panel to burn at its outer face, and a conduit for non-combustible gas extends along the margin of the panel and discharges the non-combustible gas through the panel all along its margin to keep the combustion mixture from escaping through the panel edges where burning can damage the panel and to keep the panel support relatively cool.  No further sealing of the panel margin is needed, but the sealing is effected with less of non-combustible gas if the panel edges are compressed so as to reduce their thickness about 10%.  One or more of the margins of a rectangular panel can be arranged as a depending flange with its mounting at least partially recessed 90 that two or more panels can be juxtaposed at such margins to form an effect-ively continuous radiating surface of relatively large size.          The air seal construction also makes such heaters very practical for firing house heating furnaces.

Abstract: HIGH ACCURACY MOS COMPARATOR       Abstract of the Disclosure The voltages to be compared are applied to a passive MOS capacitor differencing circuit for producing a voltage difference signal, which then is amplified by a high-gain non-precision FET amplifier, the output of which is passed through a low output impedance FET buffer amplifier to an FET latching circuit.  Capacitive coupling is used for enabling the amplifiers to be independently biased and to eliminate D.C. offsets.  The operating cycle of the comparator has two periods.  During an initial set-up or preconditioning period the amplifiers are self-biased by appropriate switching actions which cause each of the amplifiers to be set at a desired operating point that is maintained when its respective bias switching connection subsequently is opened.  The bias switch openings in the respective amplifier and latching stages are timed to occur in a chosen sequence which causes the switching transients to be absorbed.  At the end of the preconditioning period, the comparator is set up for operation in the comparison period during which the input signals are compared.

Abstract: ABSTRACT OF TEE DISCLOSURE          A process for separating saccharides by exclusion chromatography wherein a feed mixture of saccharides is supplied to a molecular exclusion chromatography zone from which at least three fractions are removed.  The first fraction contains the least diffusible saccharides of the mixture which generally are the highest molecular weight components, the second fraction contains predominantly intermediate molecular weight saccharides and the third fraction contains predominantly lower molecular weight saccharide fractions.  After supplying the feed to the column, the zone is continuously eluted, first with the first fraction removed from the column followed by elution with water.  The use of the first fraction from the column as an eluting solvent serves to minimize the amount of water employed as an eluting solvent.

Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus for casting a metal article in a mold at least as long as the article, utilizing a cooled mold of elongated form having top and bottom portions.  The method includes the steps of introducing molten metal from a source through the bottom portion of the mold, flowing molten metal into the mold so as to form a solidifying casting shell which during casting occupies at least 40% of the cross-sectional mold area and has a molten core, and flowing molten metal from the source through the core towards the mold top.  The rate of solidification is effectively governed, thereby avoiding the undesirable growth of columnar dendrites which result in localized solute con-centrations, segregated inclusions and centerline porosity, all undesirable in a casting micro-structure.
