Abstract: ABSTRACT OF THE DISCLOSURE A method of determining triglycerides in biological fluids according to an enzymatic reaction. In the reaction, a biological fluid is added to an enzyme reagent comprising a lipase, glycerol dehydrogenase (GDH), pyridine nucleotide (PN), a buffer, a tetrazolium compound and diaphorase, whereby the triglycerides are enzymatically hydrolyzed, and the resulting glycerol is oxidized to form a reduced pyridine nucleotide (PN) which reacts with said tetrazolium compound in the presence of the diaphorase to produce a colored formazan which is the reduced form of the tetrazolium, which color is measured at a wavelength ranging from about 475 to about 325 nm.  The lipase is an enzyme obtained from Chromobacterium viscosum. In the enzyme reagent, there is from about 5.0 to about 15.0 I.U./ml of the glycerol dehydrogenase (GDH) present.

Abstract: Abstract of the Invention An apparatus for the manufacture of transversely contoured tubing from thermoplastic material.  The tube emerges in the plastic state from an extrusion nozzle and is guided into a mold composed of a plurality of mold sections in series, with inner side working surfaces forming the trans-verse contours.  Each of the mold sections is composed of two mold halves which are arrayed along a straight molding run in two confronting rows and which are circulated.  In the circu-lation, the first  two halves are moved apart and out of the molding  at the end of the molding run and are guided to a return run on which they are separately returned to the beginning of the molding run where they are rejoined to the preceding mold half.  The mold halves are guided on the return run in a continuous. accelerated and then decelerated movement by a transfer mechanism which couples and uncouples from the mold halves as actuated by pneumatic cylinders under the control of limit switches.

The biconical taper sections of the fibers are fused together to provide optical coupling between the fibers.   The fused fibers may also be twisted around one another to enhance mode mixing.          The access couplers may be produced by fusing two fibers together along a small length, then heating the fused  length and pulling the fibers to form the biconical tapers; or by twisting a portion of each of the fibers around one another, applying a tensile force to the twisted portions of the fibers and heating a region of the twisted fibers to soften and fuse a predetermined length of twisted fibers.  If the fibers already have biconical taper sections, the access coupler may be produced by twisting the fibers together along their taper sections and heating a region of the taper sections to fuse them together.

Abstract: ABSTRACT OF THE DISCLOSURE     A rotary continuous ash discharge stoker having a circular grate which is designed to support burning fuel as it dis-tributes the fuel from the feedpoint over the entire grate, and at the same time provides for the controlled admission of air for combustion of the fuel and also automatically removes from the furnace the remaining ash. The upper grate surface consists of two zones, a central stationary section and an outer rotating sec-tion or ring. The central section is inclined and is the main air admitting zone. The outer rotating ring serves to distribute the fuel in the furnace with the aid of a stationary spreader arm, admits the air necessary to complete combustion of the fuel and removes the burned out ash from the furnace with the aid of a stationary ash plow. This rotating ring is supported and guided on rails and rollers which allow for the complete rotation of this section of the grate, and has an improved wear-resistant furnace wall seal at the interface between the outer periphery of the ring and the inner periphery of the furnace wall.

Abstract: ABSTRACT OF THE DISCLOSURE A process for the irradiation of homopolymers of ethylene and copolymers of ethylene and higher .alpha.-olefins is disclosed.  The process comprises subjecting the polymer in the form of granules to an atmosphere of steam, irradiating the polymer in an inert atmosphere with electron or gamma irradiation and reducing the level of free radicals in the irradiated polyethylene by further subjecting the polymer to an atmosphere of steam.  The preferred inert atmosphere is steam.  The amount of irradiation used is less than 1.5 Mrad.  The irradiated polymer, which exhibits improved pro-cessability and/or product properties when compared with non-irradiated polymer, may be used in a wide variety of end-uses e.g. fabrication into film, pipe and other arti-cles, using extrusion, injection moulding and blow moulding techniques.

Abstract: REFLECTIVE INSULATING BLINDS FOR WINDOWS AND THE LIKE     ABSTRACT OF THE DISCLOSURE     Disclosed is an improved blind for use with a window for transmitting sunlight into a room, the blind comprising a plurality of coupled, horizontally extending thermally insulating slats.  Each slat has a front face, a rear face, and a pair of longitudinally extending edge faces with each front face being a reflective transversely concave surface.          The slats are rotatable about their axes between a blind-closed position, where adjacent slats are in partially overlapping relation and form a substantially continuous, generally vertical surface for providing window insulation, and a blind-open position where the slats are in spaced, super-imposed relation, with their reflective concave surfaces  having upward and directly exposed to the sunlight.  The reflective surfaces have a curvature reflecting most of the sunlight incident thereon directly onto the ceiling of the room to maximize solar energy input to the room while minimizing glare.  The transitions between each of the edge faces of a slat and the back face thereof are sloped toward each other to enlarge the light-entrance and light-exit regions defined by adjacent slats.

Abstract: ABSTRACT A burner assembly is disclosed for the smokeless burning of low calorific value gases, or diluted hydrocarbon gases, which comprises a plural-ity of separate burner heads arranged in a horizontal array, each of the burner heads being mounted on top of a vertical pipe through which the low calorific gases are supplied.  A plurality of hollow radial arms are inserted into the wall of the hub of the head, arranged in equally-spaced array, each of the arms having a plurality of ports in the top surface, near the end of the arm. These ports are of selected size and selected angle of their axes, which are tilted inwardly towards the central axis of the burner head.  Additionally, there is between each pair of arms at least one port drilled downwardly from the inside of the burner head, at a selected angle, so that jets of gas will impinge downwardly on an annular plate which is positioned beneath the arms to close off the vertical flow to the spaces between the arms.  The arms are surrounded by a shallow cylindrical wall which is perforated in a selected uniform pattern over its entire surface.  Over each of the arms is a cylindri-cal tube against which the gas jets, which can be sonic, impinge, so that the jets are diffused throughout the entire volume between the arms and above the arms.  Air diffuses inwardly through the surrounding perforated wall to mix quietly with the gas so as to maintain a continuous combustion, with sufficient air to prevent the formation of smoke.
