Abstract: Abstract of the Disclosure A catalytic converter includes a shell defining first and second shell portions.  A first substrate supports a reducing catalyst in the first shell portion.          A second substrate supports an oxidizing catalyst in the second shell portion.  The shell further includes inlet and outlet passageways.  The inlet passageway is dis-posed in the shell adjacent the first shell portion and allows combustion products to enter the shell.  The outlet passageway is disposed adjacent the second shell portion and allows combustion products to exit from the shell.  A third passageway located longitudinally between the first and second shell portion allows com-bustion product to flow readily from the first shell portion into the second shell portion.  A manifold introduces air into the combustion product flowing through the third passageway and an air fitting provides access to the manifold through an exterior wall of the shell.  The manifold extends perimetrally at least partially about, and conforms to the interior wall of, the shell in the third passageway.  The manifold has a plurality of apertures which open inwardly to direct a plurality of streams of air from the manifold into the stream of combustion product flowing through the third passageway.  The converter can be of a "clam shell" type, having first and second longitudinal shell halves, or it can have a one piece main shell portion.

Abstract: INVENTION: HIGH PERFORMANCE, QUALITY CONTROLLED BIPOLAR MEMBRANE INVENTORS: LESTER T. C. LEE, GERALD J. DEGE, and KANG-JEN LIU ABSTRACT OF THE DISCLOSURE Improved novel single film bipolar membranes having an ion selectivity above 80% in an electrolyte medium of about one mole, are prepared containing a relatively high amount, i.e. at least 15% of an insoluble cross-linked aromatic polymer. Before the styrenated sheet is chemically functionalized, the film surface is specifically treated, i.e. cleaned to make it more receptive to functional groups, so that the cationic-exchange groups and anion-exchange groups can be introduced homogeneously from each side of the surface-cleaned film, and a single-film bipolar membrane of superior durability, stability, and quality control results.

Abstract: ABSTRACT           A controlled space is maintained at a desired set point temperature by adjusting the refrigerant temperature at the evaporator outlet in a refrigeration system, thereby controlling the evaporator effectiveness or capacity which is inversely proportional to the outlet temperature.  When the space temperature tends to vary from the desired set point due to a changing heat load, the control system auto-matically changes the refrigerant flow through the evaporator to establish the evaporator outlet temperature at the control point required to maintain the controlled space at the desired temperature.  More specifically, in response to a space temperature increase, the flow rate of the refrigerant increases; and in response to a drop below the set point, the refrigerant flow decreases.  Such control of the flow rate is achieved by varying the displacement of a controlled displacement compressor included in the refrigeration system. When the heat load on the evaporator is constant, the refrigerant flow is controlled in order to hold the evaporator outlet temperature fixed at the required control point.

Abstract: Hydrogen Probe with Limited Active Area Abstract of the Disclosure An insertion-type hydrogen probe with a defined active length is described.  The probe is formed of a thin-walled, hydrogen-permeable material, and a hydrogen-impermeable liner inside the probe blocks out all but the defined active section of the probe.  The interior of the probe is subjected to high vacuum, and the hydrogen per-meation through the active portion of the probe is deter-mined, for example, by the current output of an ion pump used with the probe.  To prevent bimetallic cell inter-face effects, the probe is constructed so that only a single metal is exposed to the primary environment being studied.

Abstract: CAPACITOR STRUCTURES WITH IMPROVED   ELECTRICAL STRESS CAPABILITY     ABSTRACT OF THE DISCLOSURE    Power capacitors with a wide electrode and a narrow electrode and a composite dielectric including a first portion adjacent the narrower electrode that is of higher dielectric constant and/or lower resistivity than the por-tion adjacent the wider electrode.  The first portion may be a porous material whose impregnation with a suitably chosen dielectric fluid results in the desired electrical proper-ties.  In such structures the narrower electrode preferably has rounded and smooth edges such as by folding.  The wide and narrow electrodes may each comprise one of the extern-ally connected capacitor electrodes.  Alternatively, the wider electrode may be electrically floating and arranged between dielectrics and a second narrower electrode in a symmetrical arrangement with the two narrower electrodes serving as the externally cconnected capacitor electrodes.         In structures as described, in which the narrower electrodes have rounded and smooth edges, further benefit is obtained by using normal aluminum foil material for elec-trodes and folding each edge substantially to the center line of the foil with the surface having a mat finish dis-posed on the outside of the folds.         In structures as described in which the wider electrode is electrically floating, it may be a separate foil element or may be a metallized layer deposited on one of the adjacent dielectric sheets.  Also the floating con-ductor may be a single continuous layer or may be of two bands each of which encompasses one of the edges of the narrower electrodes.
