Abstract: QUICK-DISCONNECT COUPLING WITH A  HEAT-SENSITIVE CUTOFF FEATURE         Abstract of the Disclosure A quick-disconnect coupling with a heat-sensitive cutoff feature for use in connecting a tank of pressurized gas (e.g., natural or LP gas) with a gas appliance, such as an outdoor gas grill. The coupling comprises interengageable plug and socket components, the latter component having a passage therethrough, a valve seat in the passage and a poppet valve in the passage comprising a valve stem and a sealing member soldered on the stem and engageable with the valve seat.  A spring is engageable with the sealing member for biasing the poppet valve to a closed position for blocking flow through the passage.  When inserted into the socket chamber, the plug component engages the valve stem for forcing the poppet valve open.  In the event the temperature of the coupling rises to a tem-perature above the melting point of the solder bond be-tween the sealing member and the valve stem, the seal-ing member is slidable on the stem into engagement with the valve seat for cutting off flow therepast.

Abstract: Abstract:   Apparatus for securing glass panels in fire barriers comprises an elongated glazing strip made of layers of sheet material adhered together.  The sheet material is formed from a slurry mixture of wood fibers and a fire retardant chemical by the use of heat and pressure.  The panels are also preferably secured by metal clips having a flat base of thin sheet material and upstanding, elongated projections from the base that are parallel to each other and spaced apart by a distance corresponding to the width of the glass panel to be secured.  This arrangement makes it possible to locate glass panels in fire barriers with-out substantial reduction in the ability of the barrier to contain a fire.

Abstract: ABSTRACT OF THE DI  LOSURE      Disclosed is an improved process for electrolytically producing alkaline chlorate, carried out at an increased temperature by using an apparatus of a column type.  The apparatus has a lower electrolysis zone, an intermediate reaction zone and an upper hydrogen-separation zone.  The reaction zone has a central hollow section and a circum-ferential hollow section surrounding the central section.          A solution to be electrolyzed is forced to circulate through the three zones by hydrogen gas generated so that the solution is allowed to flow down through the circumferential hollow section in a piston-flow manner after the hydrogen gas is separated from the solution.  While the solution is passing through the circumferential section, effective auto-oxidation of hypochlorous acid is attained thereby causing the current efficiency of the electrolysis to be improved.

Abstract: ABSTRACT     In an article suitable for wiping surfaces which comprises an elongate web substrate impregnated with a liquid composition, migration of the liquid along the length of the substrate is substantially prevented by dividing the substrate into a plurality of individual areas by means of a repeating pattern of liquid-repellent barrier material, for example, wax or certain resins, extending across the whole width of the substrate.  This measure prevents fluid loss by capillary action and evaporation when the wet substrate is stored in a dispenser.  The wet substrate is preferably used in conjunction with a dispenser having a relatively tight closure, especially one in which the closure is formed by two resilient diaphragms with out-of-register apertures.  The wet substrate delivery system may be used, for example, for hand hygiene in hospitals, washrooms or kitchens.

Abstract: CURRENT RESET FAULT INDICATOR HAVING MAGNETIC CORE CABLE ATTACHMENT ASSEMBLY               Edmund O. Schweitzer, Jr.     Abstract of the Disclosure A fault indicator for indicating the occurrence of a fault current in an electrical conductor includes a core assembly which attaches a circuit module to a monitored con-ductor and provides a concentrated magnetic flux indicative of the current level in the conductor.  A magnetic reed switch in the circuit module responds to the magnetic flux in the core assembly to condition an indicator in a remote indicator module to a fault-indicating state in the event of a fault.          To facilitate installation and removal of the circuit module from the conductor, the core assembly is formed by a plurality of laminations secured together and arranged in a generally rectangular configuration with their ends juxtaposed along one side thereof and joined with magnetically conductive inter-locking coupling members.  A spring spanning the remaining opposed sides of the core biases the coupling members into en-gagement and allows the structure to be fitted over conductors of various sizes, while maintaining a close operative associ-ation between the conductor and the magnetic reed switch in the circuit module.

Abstract: A highly efficient boiler is made up of a housing containing upper and lower left and right water manifolds. Tubes connect the left manifolds and other tubes the right manifolds. The tubes are bent toward one another to form a plurality of superposed chambers through which combustion gases must successively flow, from front to back in one chamber and from back to front within the next. Baffles may be provided in each chamber to cause the gas to traverse a sinuous path from left to right and right to left within each chamber. Adjustment of the baffles can be effected during operation to keep the combustion gas exit pressure of temperature or flow rate constant notwithstanding changes in the liquid flow rate through the tubes or the rate of combustion of fuel in the lowermost chamber.
