Abstract: An apparatus, and method of operating the apparatus, wherein a feed material is converted into a glassified condition for subsequent use or disposal. The apparatus is particularly useful for disposal of hazardous or noxious waste materials which are otherwise either difficult or expensive to dispose of. The apparatus is preferably constructed by excavating a melt zone in a quan-tity of soil or rock; and lining the melt zone with a back fill material if refractory properties are needed. The feed material is fed into the melt zone and, preferably, combusted to an ash, whereupon the heat of combustion is used to melt the ash to a molten condition: Electrodes may be used to maintain the molten feed material in a molten condition, and to maintain homogeneity of the molten materials.

Abstract: An occupant protecting system for a vehicle includes a triangular shock absorbing member which is accommodated in a folded state within an accommodating casing mounted along a roof rail.  The shock absorbing member is held stationarily at its front and rear ends to a vehicle body by fixing pins.  A movable pin mounted at a lower end of the shock absorbing member is connected through a wire to a developing or unfolding means mounted to a center pillar.  The developing or unfolding means includes a gas generator and a cylinder with a piston slidably received therein and coupled to the wire.  When the gas generator is operated upon collision of the vehicle to force the piston in the cylinder downwardly by a high pressure gas generated by the gas generator, the movable pin is pulled down through the wire, so  that  the  shock  absorbing  member  is  drawn  out  of  the accommodating casing and developed into a triangular shape. Thus,  the membrane-like shock absorbing member,  when being accommodated, is compact in size and can easily be mounted in a narrow space in the vehicle body.

Abstract: Slack-free or slackless coupling systems have application in various types of coupling arrangements such as drawbars, articulated connectors, and E and F type couplers. The gravity wedge that takes up any slack developed when the system components wear, maintains a constant longitudinal force on the follower block and coupler member butt-end interface. However, under high buff loading, that mated interface develops high friction forces during curving and angling. It has been found that the lateral component of these friction forces can become great enough to cause wheel lift at the wheel/rail interface. The present invention reduces that component of friction by greatly reducing the coefficient of friction at the coupler/follower block interface by supplying a lubricant between these surfaces. The present invention incorporates a series of lubrication retention reservoirs in the follower block front face to hold and distribute lubricant such that each time the coupler member butt-end laterally and vertically angles, lubricant within the reservoirs is wiped out of the reservoirs. The reservoirs are large enough to hold enough lubricant until the car is serviced for maintenance. Alternatively, a manual or automatic lubricant supply system can be used in conjunction with the follower block to ensure that lubricant is always held within the reservoirs.

IPC: F23D11/46

Granted: 1998-10-20
Abstract: A fuel control mechanism for a liquid fuel burner includes a fuel regulating valve which is responsive to flow of liquid fuel through a fuel feed tube for movement between a starting position and a running position.  When a fuel control valve for the burner is opened, flow of liquid fuel through the fuel feed tube moves the fuel regulating valve to a starting position in which the fuel regulating valve restricts flow of fuel through a fuel inlet.  Air is thereby drawn through an air inlet and mixes with the fuel.  After the burner is started and liquid fuel is vaporized within the generator, flow of fuel through the fuel feed tube slows, and the fuel regulating valve falls by virtue of its weight to the running position in which the fuel regulating valve does not restrict flow of fuel through the fuel inlet.  Air flow through the air inlet is thereby discontinued, and only liquid fuel flows through the fuel feed tube.

Granted: 2004-12-14
Abstract: A drum mixer (10) is disclosed which is useful in the continuous production of asphalt paving composition, and which has provision for the accurate control of the final temperature of the composition being produced. The drum mixer (10) comprises a fixedly mounted cylindrical sleeve (32) disposed in a generally horizontal orientation and rotating blades (42) for conveying the heated aggregate longitudinally through the interior of the sleeve (32). An opening (54) is provided in the side wall portion of the sleeve (32), and a box-like enclosure (55) covers the opening (54) and mounts a plurality of sensor mounting tubes (64), so as to permit one or more sensors (66) to be positioned at a location within the enclosure (55). The enclosure is located where the blades (42) or mixing action in the sleeve (32) will supply a regular flow of the aggregate into the enclosure (55), and so that the aggregate then slides over the sensors (66). The sensors (66) are thus subjected to a representative portion of the aggregate, and they are protected from both the radiant heat of the burner (27) and the physical abuse of the mixing action.

Granted: 2001-07-10
Abstract: A self-tightening side lock (20) for a roll-up door includes a keeper (25) mounted on the jamb, and a latch member (26) pivotally mounted on a door panel. The latch member is selectively cooperable with a catch (30) to hold the door in a closed position. The latch member is biased to move in a counter-clockwise direction. The latch member is adapted to be moved in a clockwise direction, against the opposing bias or a spring 42, to an out-of-the-way position at which the displaced latch may pass by the catch. The latch member has a side cam surface (33) arranged to engage the catch (30) when the door is lowered and to cause the latch member to pivot in a clockwise direc-tion toward the out-of-the-way position to allow the latch member to pass by the catch. The latch member also has an upper cam surface (34) arranged to engage the catch such that the counter-clockwise movement of the latch member will cause the door to be self-tightening. A notch (50) extends radially into the latch member from the upper cam surface adjacent the side cam surface. The notch member is so configured and arranged as to receive the catch and to prevent further pivotal movement of the latch member. The improved side lock will thwart the efforts of would-be thief who might attempt to force the door upwardly with the upper cam surface engaging the catch.
