The film with the food units thereon and a top film over the units is then subjected to vacuum and the top and the bottom films sealed.  Alter-nately the package may be back-filled with oxygen-free gas prior to being sealed about the food unit.  The dis-closure includes also the steps of partially sealing food units between top and bottom films in a first chamber, back-filling with a substantially oxygen-free gas, then vacuumizing in a second chamber, and fully sealing the packages in the second chamber, or alternately back-filling with the oxygen-free gas before fully sealing.

Abstract: ABSTRACT OF THE DISCLOSURE    A conveyor, particularly for feeding tobacco to a cut-ing drum, comprises a number of articulated slats passing around sprocket wheels.  The slats are identical and each has extensions and recesses.  The extensions of one slat enter the recesses of the next adjacent slat, and are re-tained by a pin passing through the extensions of adjacent slats.  The underside of each extension has a flat surface for contacting a support plate and the top face of the spr-ocket teeth contact the slats so that the flat underside of each extension is not contacted by the sprocket wheel, in order to maintain a constant pitch as the band travels ar-ound the sprocket wheels. In this way the spacing between the conveyor and a dead plate positioned to remove tobacco from the band as it passes over a sprocket wheel remains constant.

Abstract: ANDIRON FOR SUPPORTING LOGS     ABSTRACT OF THE DISCLOSURE     Andiron for supporting logs on a hearth in two primary fuel banks disposed in an inverted V-position to form triangular opening facing room to be heated.  Andiron has horizontal baffle member supported above and between spaced positioning  members by frame means.  Baffle member and positioning members on each side of andiron are positioned so that primary fuel banks extend between edges of baffle member and positioning members so as to be inclined at par-ticular angles with banks almost touching at apex.  Secondary fuel placed between lower ends of primary fuel banks when ignited cooperates with primary fuel to form a concentrated, triangular-sectioned combustion zone of essentially uniform temperature defined by burning faces of primary and secondary fuel.  Primary fuel burns mostly on inner faces with neg-ligible burning of outer faces which reduces convection losses up the chimney.  The inner faces of primary fuel banks and burning secondary fuel provides three radiating surfaces which tend to sustain combustion of oppositely facing radiant surfaces by absorption and re-radiation of radiant heat between the surfaces.

Abstract: DOUBLE DISC GATE VALVE WITH  REPLACEABLE SPACER RING                        ABSTRACT OF THE DISCLOSURE   A gate valve includes a pair of identically shapped tapered discs defining a tapered self-locking axially translatable gate wherein each disc has an annular hardened seating surface which engages the mating surfaces on the valve body adjacent the flow ports. Tongues on the sides of the discs ride in vertical grooves on the valve body as the gate travels between a raised open and a lowered closed position. The discs are separated by an annular spacer ring of substantially smaller diameter than the seating surfaces surrounding an inter-locking segmented hub formed on the inner juxtaposed surfaces of the discs, the arrangement being such that the spacer ring can be sized to establish an overall gate width which will ensure that the seating surfaces are making proper sealing engagement with the valve seats with the diametral differences increasing the disc flexibility. The spacer ring can be replaced by an appropriately sized spacer ring to compensate for thickness reduction in resurfacing the seating surfaces.

Abstract: IMPROVED STEAM REFORMING PROCESS AND APPARATUS THEREFOR     ABSTRACT OF THE DISCLOSURE    A tubular catalytic reactor, such as for steam reforming a hydrocarbon feedstock to produce hydrogen, is disposed within a furnace and includes an annular first bed of reac-tion catalyst.  A second bed of reaction catalyst is disposed coaxial with the first bed and inwardly thereof. Product gases from the first bed, without adding heat thereto, are passed through the second bed essentially adiabatically resulting in a substantial reduction in the amount of unreacted hydrocarbons heavier than methane which were present in the product gases leaving the first bed.  The apparatus is compact and uses only the sensible heat in the reaction products leaving the first bed to reduce the level of unwanted hydrocarbons.  Thus, in the process of the present invention, the reduction in the level of unwanted heavier hydrocarbons is accomplished in compact apparatus without burning additional fuel and without extracting additional heat energy from the furnace.

Abstract: A FIBRE NETWORK HAVING A PASSIVE OPTICAL COUPLING ELEMENT      FOR OPTOELECTRONIC TRANSMISSION OF DATA BETWEEN         ADDRESSABLE SUBSCRIBER STATIONS            ABSTRACT:            A fibre network is disclosed for the optoelectronic transmission data between and among a plurality of subscriber stations, each station having a transmitter and a receiver. A specific address code is allocated to each transmitter and its associated receiver, and the information content of the individual subscriber stations is sample cyclically by a common addressing unit.  The fibre network has n junction points, whereby n?1, and the individual fibre conductors lead from these junction points to the connected subscriber stations, in which the junction points contain passive coupling elements in the form of a solid, light-conducting core having opposing end faces.  The fibres leading from the transmitters and from the addressing unit to a junction point are optically connected to one end face of a coupling element, and the outgoing fibres leading to the re-ceivers are optically connected to the opposite end face of the coupling element.  The length of the coupling element is such that the active surface area of the light-transmitting fibres coupled to the coupling element are individually capable of fully illuminating all of the receiver fibres connected to the opposite end face of the coupling element.  In an alterna-tive embodiment, the fibres leading from both transmitters and receivers are optically connected to the same face of the coupling element, whose opposite end face is provided with a reflective (i.e. mirror) surface.
