Abstract: An improved gas fueled cooking appliance incorporating surface heating units comprising burners with automatic reignition capability adapted for use in combination with surface level downdraft venting is provided with an air deflector disposed proximate the igniter to alter the flow of air in the vicinity of the igniter so as to prevent the downdraft vent induced air flow from moving the flame from the igniter. In a preferred form the air deflector is a thin wall extending upwardly from the cooktop surface. The wall extends away from the burner with the end of the wall nearest the burner being laterally spaced from and even with or downstream from the igniter electrode located on the periphery of the burner.

Abstract: This invention relates to centrifuging machines, and more particularly to vertical axis washing machines, wherein improved vibration-isolating devices are provided to prevent unbalance-caused vibrations of the movable mass from being transmitted to the support structure of the machine to the extent that damage to or "walking" of the machine may occur.A suspension system is provided for suspending the movable mass above the machine support structure. The suspension system is formed by a plurality of circumferentially spaced spring members supported at the lower ends to the support structure. The springs are connected at their upper ends to a support member. The suspension system for supporting the movable mass on the support member includes a plurality of circumferentially spaced links which extend in the general direction of the vertical axis.

Abstract: A tube joint configuration and method of joining tubing wherein a curable adhesive is arranged on one portion and a resilient sealer is arranged on a second portion on the end portion of the male tube prior to its being telescoped with the female tube. The telescoped portion of the tubes is deformed so that a plurality of spaced grooves is formed containing areas for each of said adhesive and sealer to provide a first and second sealing area.

Abstract: Damaged end portions of tubes are repaired from a multi-tube finned coil in which the tubes are expanded into intimate contact with the fins. The method consists of removing the damaged end portion of the tube adjacent the area in which the tube projects from the coil body. A replacement stub tube member having one end dimensioned to be similar to the removed end portion and the other end portion dimensioned to be inserted into the coil tube. After the end portion dimensioned to be inserted in the coil tube is arranged therein, a portion thereof is expanded so that its inner diameter is at least equal to that of the tube coil.

Abstract: A valve assembly providing a disconnectable coupling for a split system air conditioner including an indoor unit and an outdoor unit joined by connecting tubing to complete the sealed refrigerant system. The present valve is effective in providing a disconnect system between a unit and the connecting tubing. The valve is activated by an electric coil that is applied to the valve only during the disconnecting procedure.

Abstract: The method of joining tube members including a cicumferentially arranged lip means to a wall segment having an aperture wherein the lip means and said wall segment are coated with a layer of solder and a heated forming means is applied to the lip and wall segment to reflow the solder while simultaneously applying sufficient pressure to deform the lip and wall segment to cause an oxide layer on the solder to disperse in a desultory manner so that the solder layers combine to form a joint.

Abstract: The method of joining aluminum tubing wherein a heat curable adhesive in tape form is helically wound on the end portion of one tube prior to its being telescoped with the heated end of a second tube.
