Abstract: ABSTRACT OF THE DISCLOSURE         At an injection-molding machine, an assembly for clamping a mold half to a platen comprises a bore therein and a projection on a substantially planar face of the mold half.  The projection includes an annular flange insertable into the platen bore and an annular groove defined in part by an inclined or beveled surface of the flange.  A pair of sliding plates are reciprocatably mounted in the platen for shirting from withdrawn positions inwardly to locking positions, the plates having beveled inner edges for coating with the inclined flange surface to clamp the mold half to the platen.  The bore is advantageously formed with a conical extension for accepting the head or nozzle of an injection device or extruder.  Another mold half may be clamped in an analogous  manner to another platen provided  with a bore and reciprocatably mounted locking plates, the two platens being shirtable relatively towards each other.

Abstract: ABSTRACT          LOW SULFUR CONTENT HOT REDUCING GAS PRODUCTION USING CALCIUM OXIDE DESULFURIZATION WITH WATER RECYCLE     A process and apparatus for producing a low sulfur content, hot reducing gas by desulfurizing hot reducing gas by contacting the sulfur-bearing hot reducing gas with a bed of a particulate calcium oxide desulfurizing agent to thereby produce a product gas stream and a byproduct calcium sulfide composition, and then recovering sulfur from the calcium sulfide composition by contact-ing the calcium sulfide composition with hot liquid water at a temperature and corresponding pressure sufficient to maintain steam in the system and to thereby convert the sulfide to calcium hydroxide and hydrogen sulfide and to produce a liquid water stream containing sulfur, and then combining the sulfur-containing water stream with a fresh water stream and recycling this water stream for contacting the calcium sulfide composition. Preferably water vapor produced in the contacting step is condensed and returned to the system in the final stage of contacting the calcium sulfide composition with hot liquid water.

Abstract: ABSTRACT OF THE DISCLOSURE          In a method for recovering zinc and lead from a dust containing ferric oxide, zinc oxide and lead oxide dis-charged from a metal refining metallurgical furnace, the dust is charged into the entry of a rotary kiln together with a granular carbonaceous reducing agent.  The atmosphere of the interior of the kiln comprises a reducing atmosphere zone accounting for a major portion of the interior including the entry section of the kiln and an oxidizing atmosphere zone accounting for a minor portion of the interior including at least a part of the exit section of the kiln.  The tempera-ture of the interior of the kiln is increased by the combus-tion of a fuel from at least one burner installed at the exit section of the kiln directed toward the interior of the kiln.          The dust is reduced in the reducing atmosphere zone to vaporized zinc and lead, and also to reduce the ferric oxide into ferrous oxide.  The resultant zinc and lead are reoxi-dized in the oxidizing atmosphere zone, and discharged from the kiln, together with exhaust gases produced in the kiln to recover zinc and lead.  The method includes the characterizing step of reoxidizing the ferrous oxide into the ferric oxide in the oxidizing atmosphere zone.  The characterizing step has an effect enabling saving an amount of the reducing agent used as the fuel which corresponds to the amount necessary to generating the heat corresponding to that obtained by the re-oxidation heat of the ferrous oxide.

Abstract: FUSED GLASS DETECTOR            ABSTRACT OF THE DISCLOSURE            There is disclosed herein apparatus which views a glass container from above while -the container is rotated about its vertical axis.  A source of light, preferably a laser, has its beam swept diametrically back and forth across the bottom of the container to be examined.  The inclusion of a piece of stuck or fused glass in the container will create a light output in the form of a pair of concentric halos of light above the container finish.  The halos are sensed by two concentric arrays of solar cells positioned above the container.  The output of the solar cells is fed to logic and reject electronics for selected rejection from a line of ware moving along a conveyor, depending upon whether or not the container has a piece of stuck glass therein.  The apparatus and method of determining stuck-glass is generally insensitive to mold numbers and other types of optical discontinuities that may be found in the container button because of the requirement that an output reject signal is ob-tained only when a plurality of solar cells are illuminated at the same time.

An arm is coupled to a vertical drive shaft which is rotatable about the center axis.  The arm is designed to move a circular cover from opening-to-opening to individually seal the openings from the chamber, so that the filters can be cleaned of zinc powder.  The cover is freely mounted on the distal end of the arm such that the cover is supported on the bottom surface of the chamber as it moves in an arcuate pathway between the filter openings.

Abstract: Abstract A communication system is disclosed wherein plural base stations each communicate with plural associated mobile stations in a variable but well disciplined single channel time division multiplexing arrangement.  Each base station communicates to and from its associated mobile stations in an associated unitary communication cycle having time segments of variable size but allotted for specific purposes.  The mobile stations include clocks which are all periodically synchronized by the base station.  The base station transmits cycle timing information at the beginning of each cycle so that the mobiles can determine by referring to their clocks when the various cycle segments begin and end.  The number of mobile stations participating in a communication cycle with a given base station can vary as the mobiles move from the service area of one base station to the next.  A particular time segment of each cycle is allocated for use by nonparticipating mobiles to transmit requests for participation in the cycles of the associated base station.  The mobiles wait a random delay before transmitting their requests in order to reduce the danger of interfering transmissions of two mobiles both requesting participation in the same segment.  A central traffic control center mediates the operation of the system, causing the communication cycles of adjacent base stations to occur sequentially rather than concurrently to avoid interference.
