  • Patent number: 4399756
    Abstract: A process is provided for burning refuse containing polyvinyl chloride without the consequent production of phosgene. The refuse is carbonized in a rotary furnace at temperatures below 1200 degrees F., especially 700 degrees F., in an oxygen deficient atmosphere. A burnable gas containing the carbonized refuse is drawn from the furnace by an air jet wherein same is mixed with oxygen and selectively combusted. Uncarbonized refuse is collected and withdrawn after exiting the furnace. An apparatus is provided for combustion of the refuse in the nonphosgene generating process and includes the rotary furnace. Special seals are provided for the furnace to prevent excess oxygen from entering thereinto. In particular, the seals are utilized between the rotary ends of the furnace and stationary head associated with each end respectively.

  • Patent number: 4398559
    Abstract: A valve assembly and a valve member therefor including a fluid passage in the valve assembly with inlet and outlet portions and a valve seat. The valve member includes a valve member face selectively engaging the valve seat and defining a contact area therebetween with an inlet peripheral edge adjacent the passage inlet portion, and an outlet peripheral edge adjacent the passage outlet portion. An inlet pressure relief groove extends along one of the valve seat and the valve member face from the inlet peripheral edge to an interior portion of the contact area. An outlet pressure relief groove extends along one of the valve seat and the valve member face from the outlet peripheral edge to an interior portion of the contact area. The contact area includes a continuous sealing portion whereat the valve seat and the valve member face are in engagement for preventing fluid flow from the passage inlet portion to the passage outlet portion with the valve member in its closed position.

  • Patent number: 4387587
    Abstract: The decelerating movement of a vehicle during a skid test is sensed by an accelerometer which provides an analog signal representative of the deceleration to a computer where the analog signal is periodically sampled and converted into a digital deceleration signal for storing in a computer memory. Alternatively, the decelerating movement of the vehicle may be sensed by a radar speed detector providing digital signals representative of the initial speed and final speed of a time increment to a computer processor which records and stores the digital speed signals in computer memory to be later recalled to produce a digital deceleration signal. The computer processor effects storing of the digital deceleration signals in the computer memory at the beginning of a skid test when the magnitude of the signals exceeds a predetermined threshold level as sensed by a threshold level detector or, alternatively, when a mercury position switch is operated by the deceleration force.

  • Patent number: 4384552
    Abstract: A gas producing and handling system is provided comprising a rigid reservoir enclosure containing a continuous and variable supply of gaseous fuels and a suitable engine capable of utilizing the total amount of fuel provided by the gas supply for producing electrical energy. The gas supply comprises an anaerobic digester adapted to receive organic waste and which is in gaseous flow communication with the engine. The engine has a supply regulated throttle responsive to gaseous pressure in the anaerobic digester. Upon the increased production of gas such that the gaseous pressure in the digester increases, the throttle regulator controls the throttle setting of the engine to increase the output of the engine to fully use the gas supplied by the digester, thereby eliminating the need for auxiliary gas storage devices.

  • Patent number: 4380793
    Abstract: A submersible vehicular lamp assembly comprises a base plate, an elastomeric lens base and a lens body. A lip member extends from lens body side walls and is snugly received within a groove formed in a surface of the elastomeric lens base to form a sealed, watertight inner cavity. A light bulb is resiliently mounted in the inner cavity to dampen the bulb from road induced vibrations, shocks and the like. Associated wiring for the lamp assembly passes through apertures in the lens base which are smaller than the thickness of the individual wires to prevent entry of water, dust, and other damaging elements.
