Abstract: A process and apparatus for widening the molecular distribution of ethylene polymers produced at high pressure and at high temperature by polymerizing ethylene at a pressure between 600 and 3,000 bars and at a temperature between 160 DEG  C. and 320 DEG  C., in two reactors operating in parallel. In the first reactor, the reaction takes place in the presence of less than 0.1% of hydrogen for the purpose of producing a polymer of high molecular weight. In the second reactor, the reaction takes place in the presence of 0.2 to 5% of hydrogen for the purpose of fabricating a polymer of low molecular weight. The effluents from these two reactors are expanded and then moved to a set of two separators interconnected so as to efficiently mix the polymers produced in the two reactors by recycling the least possible amount of hydrogen into the supply circuit of the first reactor in such manner that the proportion of hydrogen in the first reactor remains less than 0.1% in moles. Ethylene polymers are produced with a fluidity index between 0.1 and 2 and a polydispersity index larger than 8.

Abstract: PANEL WIRING SYSTEM             ABSTRACT OF THE DISCLOSURE         The specification discloses a hard wired, free standing movable room divider panel system in which wiring is provided for two separate circuits, one of which is especially adapted for connecting to panel mounted lighting through an internal quick disconnect connector.  This is referred to as the lighting circuit.  The second circuit is adapted only for mounting conventional outlet receptacles via quick disconnect connectors.  The wiring terminates in connectors which provide terminals for connecting into the lighting circuit, terminals for connecting into the power circuit and terminals for connecting into both circuits which facilitate electrically connecting adjacent panels through a panel power connector.  In one embodiment of the invention, conventional outlets receptacles can optionally be connected to the lighting circuit as well.  However, the two types of conventional outlets cannot be inadvertently connected to the wrong circuit.

Abstract: ABSTRACT OF THE INVENTION         A wood-burning heating apparatus, used as a parlor stove, and providing a significant heat output is disclosed.          The stove has primary and secondary combustion chambers and a baffling arrangement for directing flue gases along a circuitous path to the exit aperture whereby a significant proportion of the heat of said gases is given up to the apparatus.  A vertically oriented downwardly directed baffle separates the combustion chambers.  Primary and secondary air paths supply air to the primary and secondary combustion chambers respectively.  Each of the supply conduits is pre-heated and the secondary air supply provides oxygen substan-tially evenly around an opening at a bottom portion of the baffle to increase the efficiency of secondary combustion.          The frame has a corrugated shaped back panel for providing a larger heat radiation area.

Abstract: Abstract A catch device in agricultural equipment having at least two laterally arranged sections, which are swingable towards each other.  Through the action of an operating mechanism, such as a hydraulic cylinder, the catch means not only automatically locks the sections when they are raised to a retracted position but also automatically releases the catch device when the sections are lowered and opened out to an operative position.  This is provided by the operating mechanism being connected to a section with the aid of a means which is movable between two stops for allowing the catch device to assume a locking position when the sections are swung towards each other, while the movable means prevents the device from assuming its locking position during the swinging away from each other of the sections, this swinging movement being provided by the operating mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE Cellulose sulfate esters are cross-linked with tetravalent metal ions at a threshold pH of 3.0 of higher.  The cross-linked products have a higher aqueous viscosity and are more highly pseudoplastic than the precur-sor cellulose sulfate and may also exhibit a relatively high yeild point. The present invention thus provides a process for cross-linking of cellulose sulfate esters with tetravalent metal ions, to mixtures of cellulose sulfate esters and tetravalent metal ions that may be used in producing cross-linking of the cellulose sulfate, to a cellulose sulfate product which is cross-linked with tetravalent metal ions, and to aqueous composi-tions containing cellulose sulfate cross-linked with tetravalent metal ions.  The products may be employed in forming thichkened aqueous comoposi-tions and cohesive gel-like compositions.  The presence of other metallic ions, in addition to the tetravalent metal ions, is beneficial and enhances the viscosity increase produced by cross-linking of the cellulose sulfate with the tetravalent metal ions.

Abstract: ABSTRACT OF THE DISCLOSURE           Containers (such as metal, glass, plastic, fiber, but not limited thereto) are sterilized in a section of the apparatus having a helical or spiral belt conveyor within an insulated cas-ing through which air above atmospheric pressure at up to about 500°F. is circulated by means of a heater and blower, in a re-circulation path.  The containers then travel along a straight-line encased conveyor where sterile air above atmospheric pressure prevents ingress of non-sterile ambient air.  During part of the path through the straight-line conveyor, the contain-ers are driven by a helical screw which forces the containers into close proximity (in fact the out-turned flanges of the containers preferably overlap).  Pre-sterilized, preferably through a curtain, slit-type filler.  Other fillers, such as rotary fillers, may be used.  The speed of the containers is timed to deliver the desired product volume into the containers.          Thereafter, filled containers are accepted by a container closing machine.  Container lids or covers (herein "lids") are sterilized in a section of the apparatus where lids are moved along a con-veyor and sterile air which has been heated is forced by a blower into the lid sterilizer section.  The lids then travel up a tunnel at greater than atmospheric pressure, where they are cooled and delivered to the closing machine.  The closing machine applies the sterile lids to the containers at greater than atmospheric pressure.
