Abstract: Abstract of the Disclosure A deep compartment tray includes compartments separated by dividers which extend to between one-third and substantially the full depth of the tray.  The tray is con-structed from sheet material, such as polyester coated paper milk carton stock by cutting blanks from the stock, scoring the blank in regions where formation of wrinkles is to be avoided to induce the paper stock to fold and form as re-quired, and pre-forming and finally forming the blank into the tray between a single set of dies.  The pre-forming step and the forming step are conducted by a first female die defining the tray cavities or compartments, and surrounded by a first draw pad region, and a second male die including bosses or land areas in the compartment regions and recesses where the tray dividers are to be formed.  The male die in-cludes a set of cavities, one in each of the tray compart-ment regions.  The cavities slidably receive plungers or inserts which are movably mounted in the cavities and are spring-urged to their fully projected positions in the cavities.  A second draw pad surrounds the male die, and is mounted for resistive movement relative to the male die.          As the male die approaches the female die in a forming stroke, the first and second draw pads capture the blank.          At the same time, the plungers contact the blank surface.          As the forming stroke continues, the plungers pre-form the blank in the compartment regions between divider ridges on the female die while tension is maintained on a perimetral flange portion of the blank by the draw pads.  The plungers finally bottom out, capturing the blank between themselves and the compartment surfaces of the female die.  The remain-ing parts of the male die continue downward, finally forming the tray.

Abstract: ll A b s t r a c t A process for the in situ recovery of organic gases from ground, bedrock or bottom sediments in lakes is de-scribed. Water containing microorganisms (e.g. methane bacte-ria) and/or substances promoting the growth thereof is pumped down through injection wells or pipes, and water containing organic gases produced by said microorganisms is pumped up through extraction wells or pipes. The organic gases are then released by pressure reduction of the water. Preferably the water is pumped in a closed circuit.

Abstract: ABSTRACT           Thermostats for use in electrically heated appliances have a positive off position and are adapted for transition to a low temperature on position within a small amount (approximately one radian) of control shaft rotation.          The thermostats comprise a stacked blade assembly including a lower bimetal temperature responsive blade, an intermediate stiff spring blade and an upper less stiff flexible spring blade, with the spring blades having juxtaposed switch contacts thereon and the bimetal blade operating to separate the switch contacts when the set temperature is attained.  A control bracket mounted above the stacked blade assembly defines an opening through which a control shaft extends, the control shaft butting against the stiff spring blade and positioning it.  The shaft mounts a cam and the control bracket has a depending cam follower for the cam, wherein the spring blade urges the cam against the cam follower.  The cam has an on/off transition portion which achieves the transition of the thermostat between its positive off position with the switch contacts separated and a low temperature positive on position with the switch contacts together at good contact pressure.  In one embodiment the cam further comprises a temperature adjustment portion for adjusting temperature settings above the low temperature on position.  In another embodiment the cam is comprised of a cam bushing which threadably receives the control shaft for temperature adjust-ment, and the cam bushing and cam shaft are locked together by clutch surfaces for rotating the cam bushing to achieve the off/on transition.

Abstract: TWO-ZONE FLUID BED COMBUSTION/GASSIFICATION     Abstract of the Disclosure A method of operating a fluidized bed system in a single vessel, typically as a combustor system for power or steam generation burning high-sulfur coal or as a gasifier for high-sulfur coal, which comprises forming an entrained fluidized bed in a first space region containing a first solid bed particle component, such as sand or hematite ore containing over 90% Fe2O3, forming in a limited space region partially within the first region a dense fluidized bed containing a second solid bed particle component, such as larger particles of the hematite, both first and second component particles essentially comprising a material having long-term physical and chemical stability in the fluidized bed system so as to be substantially nonagglomerating and not subject to substantial attrition therein, effecting division of the dense fluidized bed into upper and lower zones, providing a recirculation path such as through a cyclone separator and particle reservoir for the first particle component from the first space region through the upper zone of the dense fluidized bed in the more limited space region, operating the fluidized bed system at a velocity such that the second component particles are effectively retained in the dense fluidized bed in the more limited space region, whereas the first component particles recirculate and interpenetrate through the upper zone thereof commingling with the second component particles, and main-taining different temperatures in the upper and lower zones of the dense fluidized bed.  Typically, the temperature of the upper zone of the dense fluidized bed is conducive to capture of sulfur gases by a sorbent while a high temperature in the lower zone of the dense fluidized bed is maintained to be conducive to combustion of fuel and calcination of sorbent (for combustors) or gasification of fuel (for gasifiers).

Abstract: METHOD OF BONDING WIRES TO PASSIVATED             CHIP MICROCIRCUIT CONDUCTORS                         Abstract A wire is positioned in intimate contact with a microcircuit hip above a conductor line or pad on the chip.  The line is protected by a thin film layer of passivating or insulating material deposited upon the chip.  A short pulse, focussed, energy source such as a laser beam drills a hole through or on the edge of the wire, and also opens a hole drawn through the insulating material to expose the conductor line.  Then energy is directed upon the portion of the wire surrounding the hole to melt metal from the wire down into the hole which coalesces with molten metal below to form an electrical and mechanical bond of the wire to the line.
