Abstract: ABSTRACT OF DISCLOSURE     A process for high hydroconversion of petroleum residua containing  at  least  about  25  V  % material  boiling  above 975°F to produce lower boiling hydrocarbon liquid products and avoid undesirable precipitation of asphaltene compounds. In the process, the feedstock is at least about 80 percent catalytically hydroconverted to material boiling below 975°F and containing a mixture of gas and liquid fractions, after which  the  gas  fraction  is  removed  while  maintaining  the resulting liquid fractions temperature above about 730°F to avoid  precipitation  of  asphaltene  compounds  which  causes operations   difficulties   in   the   downstream  equipment. Alternatively,  the pressure-reduced liquid fraction can be stripped  of  material  boiling  below  about  650°F  before cooling  the  liquid  to a  temperature  below about 730°F  to prevent  such precipitation of asphaltene compounds  in  the downstream  equipment.    The  resulting  liquid  fraction  is distilled  to  produce  hydrocarbon  liquid  products,  and  a vacuum bottoms fraction is recycled to the catalytic reac-tion step to obtain  increased percent conversion to lower boiling liquid products.

Abstract: Escalator Step Abstract To provide a clear, distinctive, durable demarka-tion where passengers can stand on an escalator step having treads, small grooves or slots are machined into the border area along the step, and these slots, as well as the portions of the tread below and around them, are covered with a coating having a different color than the step material.  Thus, the painted area is not in contact with the passengers feet, and an extremely distinctive checkerboard-like pattern appears around the edge of the step defining an interior area on the step where passengers should place their feet.

Abstract: ABSTRACT   The invention relates to a method for producing metallic lead from lead-contain-ing starting materials by an oxidizing smelting process and subsequent reduction of the resultant oxidic molten bath. The reduction is effected with solid carbo-naceous reduction agent present in the melt, and it is ensured that solid carbo-nate-containing material, preferably limestone, dolomite or soda ash, is also present in the melt, together with the reduction agent.     The method can be applied for working-up lead-starting materials of sulphidic, oxidic or sulphatic kind. In addition, the method can be applied to advantage for working-up lead-carbonate containing starting materials, where at least a part of the carbonate-containing material may comprise lead-starting mate-rial.

Abstract: EXPANDED INTERVAL TIMER DRIVE MECHANISM                        ABSTRACT      An expanded interval drive mechanism for a program timer includes two ratchet rings.  One of the ratchet rings is fixed to the monoblock and at certain regions thereon it is missing teeth over a portion of its width.  Thus, the first ratchet ring has regions of narrow teeth.  The other ratchet ring is arranged for free relative rotational move-ment in a first direction with respect to the monoblock. All of the teeth of the two ratchet rings have substantial-ly the same major and minor diameters.  However, the second ratchet ring is formed with at least one deep notch.  In the region where the first ratchet ring has missing teeth, the toothless region is at substantially the same level as the notch.  A single drive pawl extends over both ratchet rings and its driving surface is formed at a plurality of levels so that the drive pawl engages the first ratchet ring in the arc length corresponding to the toothless region only when the drive pawl engages the notch of the second ratchet ring.  Otherwise, in this toothless region the drive pawl only advances the second ratchet ring, there-by providing an expanded interval.

Abstract: Abstract of the Disclosure A self-aligned silicide base contact structure for a bipolar transistor,  and a process for fabricating the structure  are  disclosed.  The  structure  has  four  key elements:  a  base  region  36,  a polycrystalline  silicon emitter contact region 50, a spacer oxide 60 and 62, and a base contact 74 formed of metal silicide.  The spacer oxide is an insulator that electrically isolates the side walls of the emitter contact region from the upper surface of the base region.  The spacer oxide  is a residual amount of oxide that is left on the side walls of the emitter contact region after anisotropic etching is used to remove most of a covering layer of oxide.  The metal silicide base contact is created on an exposed upper surface of the base region, and is formed by first depositing a metal layer on the upper surface of the base region, and then heat treating.          Where metal and silicon atoms are in contact, such as along the  exposed  upper  surface  of  the  base  region,  metal silicide forms.

Abstract: AN ALTERNATE SELF-ROUTING PACKET SWITCHING NODE HAVING FAULT DIXON CAPABILITIES            Abstract A self-routing switching network interconnecting a plurality of interface controllers for communicating packets and circuit switched information via multiple paths with provision for diagnostic testing by allowing only single paths between any given set of input and output ports.  The network comprises stages of switching nodes that are grouped in pairs.  The stages are interconnected by links and each pair of switching nodes shares the same set of input links from the preceding stage. In normal operation, a pair of nodes determines one of a multiple of paths through the switching network by one of the pair responding to address information communicated via a link from an interface controller.  After establishing a path through a particular node, that node transmits the address information to the next sequential stage.  In order to perform maintenance operations, all pairs of nodes within a given stage are controlled by a single input signal which, when present, cause the nodes to cease to operate in pairs and to commence singular operation.  This results in only one path existing through the stage for a given set of input ports and output ports.
