Abstract: A vent tube has an open end adapted to communicate with an oven chamber. A catalyst is retained in the vent tube by two sets of abutments. In one embodiment, the abutments are in the form of tabs. The tabs are lanced from the wall of the vent tube and slant inwardly. The set of tabs nearer to the open end of the vent tube will flex outwardly to permit the catalyst to be inserted through the open end of the vent tube into position between the two sets of tabs. A wall of the oven chamber has an extruded hole over which the open end of the vent tube is fitted. In another embodiment, the abutments are in the form of dimples formed in the wall of the vent tube.

Abstract: A window unit for an oven door having a pair of rectangular window panels held in spaced parallel relation by a frame. The frame is an endless rectangular member. The sides and ends of the frame are generally U-shaped in cross-section having spacer flanges engaging the inner faces of the panels to hold the panels spaced apart. Retainer flanges extend laterally outwardly from the spacer flanges over the edges of the panels. Clips are provided to clamp the panels to the frame.

Abstract: A window unit for an oven door having a pair of rectangular window panels held in spaced parallel relation by a frame. The frame is in the form of a one-piece strip of flexible, bendable material which extends about the periphery of the panels. The frame has clamping sections along the edges of the window panels to clamp the panels together. The clamping sections terminate short of the corners of the panels so that the corners are exposed and not subject to pressure and chipping by the frame. At the corners, the frame has spacers which extend between the panels to hold the panels spaced apart. The clamping sections and spacers are integral parts of the one-piece frame.

Abstract: A handle assembly for an oven door or the like. The handle assembly comprises a handle grip section and an end cap at each end. The handle grip section is a longitudinally split tubular member. The end caps are capable of mounting the handle grip section in either of two rotative positions 90.degree. apart.

Abstract: An oven door having an inner panel between the back and front panels. The back and inner panels have aligned window openings. A window unit between the back panel and inner panel has a pair of glass panes aligned with the window openings. A suspended glass pane between the inner panel and front panel is aligned with the window openings. The front panel has a glass pane provided with a viewing area aligned with the window openings, or it may have a window opening aligned with the window openings in the back and inner panels and there may be another suspended glass pane to cover the window opening in the front panel. Fasteners connect the inner panel window unit and suspended glass pane or panes to the back panel.

Abstract: A self-contained window unit that may be installed in a solid fuel burner or like device. The window unit comprises a safety shield which may consist of a glass pane and/or a safety screen, and a frame surrounding the safety shield. The frame is composed of frame elements fabricated in separate lengths with brackets at the corners of the frame to secure the frame elements together. Preferably there is a cushion element between the safety shield and the frame to minimize the risk of breakage. The unit may be mounted on the fuel burner by hanger brackets on the frame or by threaded studs carried by the brackets.

Abstract: An oven door in which the top section or member of the door frame has a forward extension that serves as a door handle. End caps are secured to the door frame at the ends of the top frame member and cover and conceal the mitered corners at the top of the door. In a second embodiment the door frame has a bar-type handle.

Abstract: A machine is provided for cutting to length and joining two lengths of strand material at their ends to produce a band. A method of producing a band from two lengths of strand material is also provided.

Abstract: A self-contained window unit adapted to be assembled into an oven door, having three glass panes and a microwave shield. Two of the glass panes are held in spaced parallel relation by a frame of electrically-conducting material which has a peripheral mounting flange in electrical contact with the edge of the microwave shield. The third pane is secured to the frame by a plurality of individual mounting clips. Fasteners around the four sides of the window unit secure the mounting flange to the door to both mount the window unit and ground the microwave shield.

Abstract: Window structure for a solar collector shield or the like having a frame defining a row of separate window openings. A self-contained window unit is installed in each opening. Each window unit comprises a pair of rectangular glass panes held in laterally spaced parallel relation by a peripheral window frame. A mounting frame is provided for mounting each window unit in its window opening. Each mounting frame has overlapping frame members. Adjacent side frame members of adjacent window units also overlap. The overlap is for the purpose of excluding moisture and preventing heat loss. A peripheral window seal is provided for the same purpose.

Abstract: A new alloy of aluminum is disclosed which consists essentially of residual silicon up to 0.60 percent, residual iron up to 0.70 percent, residual zinc up to 0.30 percent, 0.05 to 0.20 percent copper, 0.40 to 0.90 percent manganese, and balance essentially aluminum. The properties of the alloy are especially conducive to producing sheet metal stock cast by continuous methods and have a general wide-ranging utility for forming many products, heretofore unobtainable from a continuous casting method.

Abstract: A method and apparatus for recovering flux salt and recycling or reusing the same in an aluminum refining method is disclosed.

Abstract: A method of recovering aluminum metal values and salt cake and recycling or reusing the same in an aluminum refining method is disclosed.

Abstract: A method and apparatus for recovering flux salt and recycling or reusing the same in an aluminum refining method by introducing salt brine into a cylindrical evaporator with hot evaporator gas, rotating the evaporator to expose the brine to the hot gas and removing the slurry from the evaporator.

Abstract: A self-contained window unit adapted to be assembled into an oven door, comprising a pair of glass panes and a microwave shield. The glass panes are held in spaced parallel relation by a frame of electrically conducting material which has a peripheral mounting flange in electrical contact with the edge of the microwave shield. Fasteners around the four sides of the window unit secure the mounting flange to the door to both mount the window unit and ground the microwave shield.

Abstract: A self-contained flange mount window unit adapted to be assembled in an oven door. The windor unit comprises a pair of glass panes held in spaced parallel relation by a substantially continuous frame-spacer of integral one-piece construction which is made from an elongated member that is bent to substantially rectangular final form and is retained in final form by a tab at one end engaging a slot at the other end. The frame-spacer has an integral mounting flange projecting laterally outwardly from the top, bottom and sides of the window unit. The window unit is secured to the back panel of the oven door by fasteners which pinch the mounting flange between the air baffle of the door and the clamping surfaces of a plurality of bridge spacer members.

Abstract: Self-contained window units adapted for assembly into an oven door of the type having a vertical air passage for the flow of air by convection through the space between the front and back door panels, the window units having two glass panes, means holding the glass panes in spaced parallel relation and having openings therein defining an air flow passage between the panes aligned with the air passage through the door. Several modifications disclosed show various means of providing for easy removal of one or both of the panes for cleaning.
