Abstract: Abstract of the Disclosure Alumina particle catalysts which can be used for auto emission control and especially as a three-way catalyst have increased performance.  The alumina particles which are preferably spheroids have a low compacted bulk density of about 20 to 36 pounds per cubic foot and a smaller size on the order of less than 2.6 mm for the preferred spheroids.  The spheroid embodiment also has a high crush strength.  Because of the small size the ratio of the geometric surface area to the bulk volume (GSA/BV) is at least about 14 cm2/cm3.  These alumina particles are impregnated with a catalytically-effective amount of one or more platinum group metals such as platinum, palladium or rhodium and additional promoters can also be added.  In the preferred embodiment the alumina particles have a GSA/BV ratio of from about 17 to 25 cm2/cm3 for substantially improved performance.

Abstract: RCA 79,533 PHASE-LOCKED SEMICONDUCTOR LASER ARRAY AND           A METHOD OF MAKING SAME ABSTRACT OF THE DISCLOSURE A phase-locked laser array including a plurality of closely spaced channels in the surface of the substrate with lands therebetween with the laser oscillation occur-ring in a cavity region over each of the channels.  A broad-area electrical contact provides uniform electrical current flow to each of the lasing regions.  The individual oscillators are coupled by the overlap of their evanescent optical fields.  The invention also includes a method of fabricating this array which includes the steps of forming a plurality of corrugations in the surface of a substrate, forming a solution having a super-saturated growth condition for planar and concave surfaces and an under-saturated growth condition for convex surfaces, contacting the corrugated surface to the solution thereby partially melting the convex portions of the surface and forming planar lands between the concave portions of the corrugations.  Growth over the lands is delayed thereby providing a planar surface of the first layer upon which the remaining layers are then sequentially deposited.

Abstract: ABSTRACT OF THE DISCLOSURE         A dart game for use with "safe" darts has enhanced electronic scorekeeping reliability.   The dart game has a target including target sections for receiving thrown safe darts, the target sections being slidably mounted in a spider target frame.  The spider and target sections are mounted in front of a pressure sensitive switch matrix for electronic sensing of dart hits.  An apertured sheet of resilient material placed between the target sections and the switch matrix creates a gap through which an impacted target section must be displaced before it can compress and close an associ-ated switch in the switch matrix, thereby enhancing the con-tinuity and prolonging the duration of the switch contact.          Ridges on the target section sides ensure ease of motion of the target section in the spider target frame.

Abstract: UMBRELLA RIB LINKAGE SYSTEM     Abstract of the Disclosure A rib linkage system of the topless type.  A stretcher rib connects the umbrella's runner with each cover rib, a support rib connects the umbrella's ferrule with each stretcher ribboned a control link connects each support rib with its associated cover rib.  The connection of the support rib with the stretcher rib is by means of a split or bifurcated brace structure that enhances the stability of the linkage system when the umbrella is full opened.  The control link, support rib, stretcher rib, and cover rib all cooperate to define a generally parallelogram configuration beneath the stretcher rib when the umbrella is in between its full opened and full closed positions, and to define a generally triangular configuration when the umbrella is full opened, again to enhance the stability of the linkage system when the umbrella is opened and also to permit the umbrella to collapse into a short and compact storage or full closed position.

Abstract: Abstract The invention provides improved lock assemblies for locking two construction components together.  A pair of tandem male lock assemblies each includes a rigid pin which is reciprocable with respect to a surrounding male socket between an advanced position and a retracted position.  Each male lock assembly includes a transversely reciprocable lock adapted to lock the pin in at least one of, and preferably both of, its two positions.  All parts of each lock assemblies are retained against separation.  The locks of the tandem male lock assemblies are connected for joint movement and are adapted so that, when moved from release positions to pin-locking positions, one lock engages its respective pin before the other lock engages its pin.  A cooperative pair of tandem female lock assemblies may have identical jointly movable locks.  The invention also relates to a construction component having a plurality of such male and female lock assemblies for engagement with female and male lock assemblies of a  similar construction component for locking the two components together.

Abstract: TOLL FRAUD CONTROL             Abstract A system and method are disclosed for automatically disabling call communications through a switching system until answer supervision is received for the call.  A four-wire switching system includes a fraud control unit which disables communications over the established transmit portion of a four-wire call connection through the switching system and prevents normal communications from a calling to a called line. However, normal call progress signals are allowed to pass on the established receive portion of the call connection from the called to the calling line.  The fraud control unit includes a generator for generating idle code and a selector for inserting either the idle code from the generator or caller communications on the transmit portion of the call connection from the calling to the called line.  The selector is controlled by a selector control unit under the control of the central processor of the switching system.  When answer supervision is received for the call, the central processor causes the fraud control unit to remove the disabling of communications on the transmit path so that normal communication may proceed from the calling to the called line.
