Abstract: ABSTRACT     An articulated vehicle includes a pivotal connection to permit movement between the chassis portions about a vertical and a horizontal axis.  To reduce lateral deflection between the chassis portions a torque transmitting linkage is mounted at -roof level and comprises a pivoted link mounted on a vertical pin on one of the chassis members.  A pair of lateral links extend from the pivoted link to the other of the chassis members.  The lateral links are generally parallel and prevent pivotal movement of the pivoted link upon a lateral force being applied to one of the chassis members.

Abstract: DRIVING FORCE CONTROL SYSTEM FOR IMPACT PRINTER           ABSTRACT OF THE DISCLOSURE    In a drive circuit for an electromagnetic printing element of a matrix impact printer, a drive pulse drives the printing element from the backstop toward a record medium to print indicia, and a damping pulse, applied to the printing element after its return to the backstop, urges it toward the backstop to limit rebound therefrom.  Logical control circuitry is responsive to overlap of a drive pulse with a preceding damping pulse for terminating the damping pulse and for decreasing the width of the drive pulse in proportion to the amount of overlap.  Blanking means are provided to prevent application of a damping pulse to the printing element until after the completion of a preceding drive pulse and after impact of the printing element with the record medium and with the backstop.

Abstract: ABSTRACT OF THE DISCLOSURE Novel very hard compositions of matter are prepared by using in all embodiments only a minor amount of a particu-lar carbide (or materials which can form the carbide in situ when subjected to heat and pressure); and no stra-tegic cobalt is needed.  Under a particular range of con-ditions, densified compositions of matter of the invention are prepared having hardnesses on the Rockwell A test sub-stantially equal to the hardness of pure tungsten carbide and to two of the hardest commercial cobalt-bonded tung-sten carbides.  Alternately, other compositions of the invention which have slightly lower hardnesses than those described above in one embodiment also possess the advan-tage of requiring no tungsten and in another embodiment possess the advantage of having a good fracture toughness value.  Photomicrographs show that the shapes of the grains of the alloy mixture with which the minor amount of carbide (or carbide-formers) is mixed are radically alter-ed from large, rounded to small, very angular by the addi-tion of the carbide.  Superiority of one of these hard compositions of matter over cobalt-bonded tungsten carbide for ultra-high pressure anvil applications was demonstrated.

Abstract: ABSTRACT OF THE DISCLOSURE         In a case where filament-like articles (e.g. wires) are dip-coated by upwardly passing the article into a bath of molten metal through the bottom and top vertical openings of a spout con-taining the molten metal, the article to be coated is wrapped, before it enters the bottom inlet opening in the spout, with a blanket of protective gas at a pressure sufficient to cause the gas to penetrate into the spout simultaneously with the article, progressively and regularly to circulate around the molten metal and steadily to emerge from the upper opening of the spout still effectively shielding the freshly coated article.  Better coating quality is thus obtained.

Abstract: ABSTRACT         Conventional industry practice has been to provide apex seals along adjoining intersecting peripheral surfaces of the envelope members in trochoidal rotary devices.  The trochoidal member profiles are then recessed by a seal offset amount and the seals extended from the apices of the envelope member by the seal offset amount to minimize reciprocation of the seals in their grooves.  In accordance with the invention, modified epitrochoids and corresponding envelopes are formed so that sealing faces of the apex seals can be substantially continuous with the envelope peripheral surfaces.  In this manner, nearly ideal expansion ratios are achievable in such rotary devices and wider sealing faces can be used than heretofore practical.

Abstract: Abstract:        The invention provides a process for fabricating devices comprising at least one n-type or intrinsic III-V compound semiconductor material.  The process comprises at least one step in which gold is plated on a metallic surface electrically connected to the III-V compound semiconductor by an oxidation-reduction reaction in an electrolytic solution.  The oxidation is carried out by illuminating the III-V compound semiconductor with light with photon energy at least as great as the band gap of the compound semiconductor so as to create holes that permit oxidation of the semiconductor.  The electrolytic solution comprises a source of gold which on reduction yields metallic gold, and the source of gold is reduced on the metallic surface to form metallic gold.  This provides a reliable procedure for inducing plating at preselected areas on a compound semiconductor structure.

Abstract: Abstract of the Disclosure This specification discloses a method for generating a table of engine calibration control values for an adaptive spark and exhaust gas recirculation (EGR) control strategy.  The adaptive strategy adjusts spark timing and magnitude of EGR as a function of engine energy usage per distance traveled while maintaining feedgas emissions at a constant level over a wide variety of driving patterns including urban, suburban and highway.  This adaptive strategy has advantageous fuel consumption characteristics which are greatest at the most constrained feedgas levels. Drivability can be enhanced because of the greater calibration flexibility inherent to the adaptive technique.

Abstract: NECKED-IN CONTAINER BODY AND APPARATUS FOR AND METHOD OF FORMING SAME          ABSTRACT OF THE DISCLOSURE          This relates to the necking-in of a free end portion of a container, and particularly a very thin wall can body, utilizing necking-in tooling.  The tooling differs from conventional tooling in that in addition to the necking-in operation, it also serves radially inwardly to turn the free edge portion of the container body to facilitate leading-in of the necked-in portion into another tubular container component with the in-turned free edge portion also providing a section modulus which effects stiffening and form retaining of the free end portion.  In addition, it has been found that conventional necking-in tooling for aluminum can bodies having a free edge thick-ness on the order of 0.0075 inch will not perform satis-factorily  on like can bodies having a free edge thickness on the order of 0.006 inch, and that surprisingly by in-creasing an adjacent radius, the tooling will perform satisfactorily.  This abstract forms no part of the speci-fication of this application and is not to be construed as limiting the claims of the application.
