Telephone apparatus mounted on an airplane food and beverage tray which is pivotable from a storage position nearly flush with the back of a seat of an airplane to a position of use, and includes a telephone handset that in a storage position in a tray recess is substantially flush with the surface of the tray that the recess opens through, the handset including a microphone portion and a combination credit card reader and speaker portion resiliently urged to an inclined condition relative to the microphone portion, latch mechanism to releasably retain the handset in the tray recess, a reel mounted in the tray that is resiliently retained in a datum position that the telephone cord connected to the handset is tightly wound and the second telephone cord that is electrically connected in the reel to the first cord is loosely wound, the second cord being connected to a terminal on a wall of the airplane which in turn is electrically connected through a computer to the primary telephone transmitter. The telephone apparatus may also be used on a desk to in a non-use condition be flush with the desk top.

An improved waste oil heater that includes a vaporizer pan having a mounting ring, a replaceable aluminum foil piece mounted on the ring to form the bottom of the pan and a member mounted on the ring to provide threads, a tool threadingly engageable with the threaded ring member for breaking the pan loose from the bottom wall of a burner pot and removing the ring with caked residue thereon for purposes of cleaning, the burner pot having a novel arrangement of apertures for flow of air into the pot, and solid state electronic control apparatus to control the feed of waste oil that automatically compensates for variations in viscosities and caloric values found in a variety of used oils and automatically discontinues the feed in the event the flame in the burner pot goes out. A thermocouple in the exhaust gas stream in the heater or in the stack senses the exhaust gas temperature and the control circuit operates the motor of the pump to feed oil to the pan at a fast or slow rate as determined by a room thermostat and the sensed stack gas temperature. The feeding of oil by the pump is controlled by the thermostat which alters the effect of the thermocouple by requiring a higher thermocouple voltage to produce slow feeding when the thermostat calls for more heat to be produced.

Pyrolytic apparatus for recycling discarded rubber tires and the like that includes an auto clave shell that is closed at both ends to provide a closed vessel and has an interior refractory lining enclosing a reactor chamber and in conjunction with the vessel forms a gas-oil separation chamber surrounding the lining, heat exchangers within the lining, burners exterior of the vessel for conducting heat to the heat exchangers, a compressor for withdrawing pyrolytic gas given off by the pyrolytic decomposition of tires in the reactor chamber and conducting it to a recovered gas storage tank and a line for conducting oil given off by the decomposition of tires in the reactor chamber to an oil storage tank. The vessel walls are of a sufficiently lower temperature than that in the reactor chamber that the oil condenses on the vessel walls. The vaporized oil and recovered gas passes through cracks between the refractory lining blocks to move from the reactor chamber to the gas-oil separation chamber, a pop-off safety valve on the vessel and opening to the last mentioned chamber being provided to prevent the pressure in the vessel increasing above a preselected level.
