Abstract: COATED METAL ELECTRODE WITH IMPROVED       BARRIER LAYER     ABSTRACT   An electrode for use in electrolytic processes comprises a substrate of film-forming metal such as titanium having a porous electrocatalytic coating comprising at least one platinum-group metal and/or oxide thereof possibly mixed with other metal oxides, in an amount of at least about 2 g/m2 of the platinum-group metal(s) per projected surface area of the substrate.  Below the coating is a preformed barrier layer constituted by a surface oxide film grown up from the substrate.  This preformed barrier layer has rhodium and/or iridium as metal or compound incorporated in the surface oxide film during formation thereof in an amount of up to 1 g/m2 (as metal) per projected surface area of the substrate.                           ???

Abstract: MOWING ROTOR                        Abstract A flail-type mowing rotor, spinning about a horizontal axis transverse to its path of travel, has specially configured, swingable cutters that provide finish-cut quality notwithstanding design features that minimize the number of cutters required on the rotor, allow them to be fabricated from stamped, relatively light-gauge metal, and promote quick and easy removal and replacement of cutters as may be necessary or desirable.  Each of the cutters comprises a pair of back-to-back, generally L-shaped blades having a medially dis-posed, obliquely oriented offsetting portion that locates the transverse cutting edge in offset relationship to the plane of the flat mounting portion of the blade.  Thus, when the blades are disposed back-to-back on the rotor, the transverse cutting edge formed by the two cooperating blades is interrupted at its midpoint to present a gap through which uncut grass may pass as the rotor spins, thereby wiping the cutter clean and eliminating grass wrap.  Arranging the cutters in a helical series about and along the hub of the rotor causes the cutting edge of one cutter in the series to overlap the gap of the next adjacent cutter in the series, thereby assuring a complete cut.  Formed contours on each blade provide a bottom cutting and bottom sharpening design as well as induce a grass-lifting airflow tending to encourage the grass to stand upright for complete severance, and the mounting hardware for the cutters is such that the back-to-back relationship of the blades of each cutter is maintained without sacrificing the ability of the cutters to yield instantaneously in a retrograde swinging motion upon striking solid obstructions.

Abstract: ABSTRACT A thin electron accumulation layer is generated along a heterojunction between two kinds of semiconductors each of which has a different electron affinity.  This electron accumulation suffers less ionized-impurity scattering, because the thickness does not exceed the spread of an electron wave.  A chan-nel constituted with this electron accumulation enjoys an excellent electron mobility, particularly at cryogenic temperatures.  A layer configuration fab-ricated with two different semiconductors having different electron mobilities and a similar crystal lattice coefficient, and including a single heterojunction is effective to improve electron mobility.  Such a layer configuration can be employed for production of an active semiconductor device with high electron mobility, resulting in a high switching speed.  The semiconductor devices including an FET, a CCD, etc., exhibit an excellent transfer conductance Gm.

Abstract: IMPROVED PROCESS FOR PRODUCING AN ON-OFF PUSH SWITCH AND RESULTING ARTICLE                   ABSTRACT OF THE DISCLOSURE     A method for producing a rotary on-off switch in Which a contactor plate is formed from sheet metal stock, integrally molded with a switch housing and thereafter blanked from the sheet metal stock.  The switch housing has an inte-gral set of circumferentially spaced abutments at regular intervals in an internal socket opening of the housing.  A first switch operating member having a stem and a plurality of crowned teeth is internally mounted in the housing.  A second switch operating member also has a set of crowned teeth disposed complementary to those on the first switch operating member, and also is disposed in the housing so that upon co-axial movement of the two operating members the second switch operating member will be caused to rotate abruptly after the second switch operating member has been displaced axially sufficiently to disengage the second switch operating member from the abutments in the housing.  This described coaxial movement occurs manually, and a spring effects restoration of the two operating members to their original positions to the accompaniment of additional angular movement of the second switch operating member.  An annular drive arm is coupled to the second switch operating member for angular movement therewith, and has resilient upwardly extending con-tactor paddles biased against and slidably contacting the contactor plate.

Abstract: Abstract of the Disclosure A reduction of the voltage across an electrolysis cell in which hydrogen is produced in the sulfuric acid hybrid closed cycle process by use of an electrolysis cell having an intermediate chamber between the anode and cathode chamber through which a separate electrolyte is caused to flow, is obtainable under operation with the electrolytes in both the cathode and the anode chambers having a concentration of sulfuric acid by weight of about 50% or more.  It is found that the undesired formation of hydrogen sulfide and of sulfur remains at a tolerable small level if the catholyte is continuously renewed.  A low specific resistance cation membrane is preferably used between the cathode and intermediate chambers, as well as between the anode and inter-mediate chambers.

The control-ler adjusts the air/fuel ratio of the mixture supplied to the engine in accord with the sum of the first and second signals and in a direction tending to produce the stoichiometric ratio.
