Abstract: A barbecue oven is provided for cooking and smoking food. The oven includes a grease control system for the door of the oven comprising an inset portion and a door grease deflector cooperating to direct grease and moisture deposited on the inner door surface during cooking to the bottom interior surface of the oven. The oven also includes an electrical heating element support and wood tray assembly. An electrical heating element is supported within the assembly and protected from contact with grease or moisture within the oven. The heating element support confines heat generated by the heating element to create an area beneath the top surface of the heating element support having a relatively elevated temperature. This elevated temperature enhances the natural convection within the oven to uniformly heat the cooking area and also causes the wood within the wood tray assembly to smoulder. Multiple apertures in the assembly aid the convection flow for efficient heat transfer to the oven.

Each fin is provided with an energy absorbant coating on one side thereof and has a reflective coating surface on the other so that upon normally aligning the absorbant side of the fins with respect to the sun's rays, the air within the chamber is heated and directed to the warm air outlet causing cold air to be drawn into the chamber through the cool air inlet. Reversal of the orientation of the fins causes incoming rays to be reflected.

Abstract: A process for rejuvenating and recycling used asphalt and a machine including a pugmill mixing chamber for mixing crushed asphalt supplied thereto and for mixing water, calcium oxide and asphalt oil therewith is disclosed. The water and calcium oxide mixture react and chemically combine to form a calcium hydroxide filler material to thus fill the voids and gaps in the rejuvenated asphalt that would otherwise exist. The reaction, being exothermic, increases the temperature of the resultant asphalt based mixture to a level suitable for spreading of the rejuvenated material on a prepared surface. The asphalt oil is preferably preheated using a heat exchanger coil connected to a diesel engine radiator, which coil is immersed in an asphalt oil storage tank carried on the machine so that the viscosity of the oil may be reduced to a reasonable value suitable for pumping to the mixing chamber and spraying on the materials contained therein.

Abstract: A fixed array of three identical directional receivers, each having a carid directional pattern, are arranged in a symmetrical configuration with each receiver having its principal axis of maximum sensitivity oriented 120.degree. from the corresponding axes of its neighbors. By comparing the relative magnitudes of the voltages generated in each of the three cardioid receivers upon receiving a signal, the bearing of the signal source is automatically determined and displayed. The tri-cardioid receiving array overcomes the prior art need for large-sized directional receiving transducers, and also overcomes the need for mechanically rotating or electronically scanning the receiving array to find the bearing of the signal source.
