Abstract: The next stud is blown under pressure into the receiver after a stud has been welded and as the rod which locates the stud for welding is withdrawn to its fully retracted position the next stud is first subjected to a vacuum which draws the next stud into the collet and then blown fully into the collet.

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.

Abstract: A barbecue oven is provided for cooking and smoking food. The oven includes a grease control system for controlling and containing grease and moisture produced by the food during cooking operations. An air control system is provided which includes passive features for insuring that there is adequate air circulation within the oven during cooking operations. The oven includes an inner oven liner defining a cooking area. An ash pan, an electrical heating element and a wood tray are assembled within the cooking area for cooking and smoking food within the oven. The temperature range within the oven is controlled by a thermostat that includes a temperature sensor mounted on the exterior surface of the oven liner. The oven includes an oven door and at least one wear-resistant latch for securing the door in a closed position.
