Abstract: Abstract of the Disclosure A method of closing a container with a "roll-on" type of screw threaded closure, comprises taking a closure blank with a  moulded resilient gasket on the inner face of the end wall, the gasket being profiled so as to have a central circular panel  and an adjoining annular bead which, when viewed in an axial cross-section through the closure, consists of a hump projecting above the level of the central panel of the gasket and terminating just short of the skirt of the closure, with the centre of area of the hump disposed closer to the skirt of the closure than is the centre of the base line of the hump.  The closure and container neck  are depressed axially to-gether to close the bottle-neck and to compress the hump-shaped bead of the closure axially and to deform the hump-shaped bead radially outwardly towards the skirt of the closure.  The closure is reformed  y diametral contraction of the root of the closure skirt above the threads of the container neck under "tight" reform conditions so that the bead of the gasket acts as at least a partial side seal against the upper part of the neck of the container.  The closure skirt is then deformed radially inwardly against the threads of the bottle neck to for  threads in the closure skirt corresponding to the threads on the container neck.

Abstract: AN IMPROVED SCHOTTKY BARRIER CONTACT        AND METHODS OF FABRICATION THEREOF                       ABSTRACT     An aluminum-transition metal Schottky barrier contact, and methods of fabrication thereof are disclosed.  In one preferred embodiment, the junction is comprised of an aluminum-tantalum intermetallic layer abutting a silicon substrate.  Alternate embodiments utilize an intermetallic compound of a metal selected from the group of tantalum, zirconium, hafnium, niobium, titanium and nickel in com-bination with aluminum.  The preferred embodiments can be fabricated by evaporation of a layer of a metal selected from the above mentioned group followed by evaporation of a layer of aluminum on a silicon substrate, after which an annealing step is utilized which creates the desired inter-metallic compound in a layer abutting the silicon surface.    Alternatively, the junction can be created by hot or cold sputtering of a preselected intermetallic compound of one of the metals with aluminum directly upon the silicon sub-strate, followed by deposition of a conductive layer such as aluminum.  In the case of cold sputtering an annealing step is required to perfect the desired intermetallic com-pound structure; and in the case of hot sputtering an annealing step may be useful in perfecting the desired inter-metallic structure, although it is not essential.  The result-ing devices are highly thermally stable with predictable barrier heights; and exhibit excellent electrical properties while they are capable of fabrication with good planarity.

Abstract: FILM GUIDANCE APPARATUS            ABSTRACT OF THE DISCLOSURE        Improved quality and flexibility of development in automatic film processing machines is achieved by mount-ing a special film guidance apparatus ahead of the first processing tank.  This film guidance apparatus determines the paths along which the various film strips are intro-duced into the processing machine.        The film guidance apparatus has transport rollers forming at least one nip, in front of which there are vanes spaced apart across  the width of the transport rollers.          These vanes subdivide the space in front of the nip into several channels, with side walls formed by the vanes.        Each film strip is introduced into the processing machine by first passing it between the adjacent vanes, and then into the nip of the film guidance apparatus.  From there, it is carried to the first processing tank of the machine by the transport rollers of the film guidance ap-paratus.        Each individual vane can be flipped into or out of the film insertion path, enabling the machine operator to quick-ly and easily adjust the widths of the film insertion channels to accomodate film strips of different widths.        An auxiliary roller aids in unrolling the film strips from their conventional spiral configuration.        Film strips of assorted widths can thus be processed side-by-side through an automatic machine, with efficient use of machine width and without risk of interference with each other or with machine operation.                             -1a-

Abstract: ABSTRACT OF THE DISCLOSURE A specially modified and adapted fluidized bed is used for heat transfer between gas streams, which have a substan-tial temperature differential. The fluidized bed is provided with first and second inlet ports for the gases and first and second upper zones, in respective substantial vertical alignment with one another, with outlet ports in the upper zones. The hot gas is led in through the first inlet port and out through the first outlet port, whilst the cooler gas is led in through the second inlet port and out through the second outlet port.  Particles of the fluidized bed are permitted to flow between the hot zone and the cooler zone of the fluidized bed, but no significant mixing of the two gas streams takes place in the fluidized bed. Efficient heat transfer is affected through the bed.  The apparatus may be used in a heat transfer process with inert fluidized bed particles, and may also be used in the fluidized bed gasification of coal, feeding air in through the first inlet port to cause exothermic reaction wiht the coal, and feeding water vapour in through the second inlet for gasification of She coal.  In this manner, the exothermic reaction provides heat which is transferred to maintain the endothermic reaction in coal gasification.

Abstract: ABSTRACT OF THE DISCLOSURE       A TDMA multiplexer-demultiplexer includes a plurality of input/output ports and common control equipment.  Each input port is capable of accepting information asynchronous to the TDMA clock and at typical terrestial clock rates.  The input/ output ports perform all the necessary signal processing for a TDMA terminal  including pulse stuffing, changing continuous asynchronous low rate information to high bit rate burst form as well as forward acting error correcting encoding, if desir-able.  By incorporating all the signal processing in the multi-plexer-demultiplexer, much equipment duplication is eliminated along with eliminating a requirement for multiple high frequency control and timing signal line drivers and buffers.  More par-ticularly, the transmit side of each port includes a separate elastic buffer to raise the input rate to a synchronous common higher rate.  In addition, on the receive side, clocking on the low speed side of the expansion buffer is derived from the sta-tion's  transmit clock.

Abstract: ENERGY EFFICIENT SKYLIGHT CONSTRUCTION           Abstract of the Disclosure An energy efficient skylight construction.  A skylight cover is secured by a frame to a curbing comprised of an insulat-ing core, the interior and exterior surfaces of which are covered by non-combustible shields separated along the upper and lower surfaces of the curbing by a gap which serves as a "thermal break" between the highly conductive inner and outer shields.  The frame is pierced by drain  openings the exterior of which are covered by a filter type material such as foam or glass fibers that is both absorbtive of moisture and resistant to the passage of air. The frame is secured to  the  outward portion of the curbing and includes a flange extending inward across the gap between the shields, which serves as a gutter to collect condensation which drips off the  glazing.  The inward portion of the flange is covered with an insulating gasket which prevents condensation from forming on the flange and which prevents the warmer, more moisture laden, inside air from reaching the cold underside of the gutter flange or the  edge of the outer skin.  The core insulation is inserted, without adhesives, into the assembled inside skin, and then the  exposed surface of the insulation is bonded to the in-side surface of the outer skin.   1.
