Abstract: A dual circuit condenser for a cooling system is configured to cool refrigerant passing through the condenser. Operation of a first circuit of the system establishes a first temperature at a first area of the condenser, and operation of a second circuit of the system establishes a second temperature at a second area of the condenser. The condenser includes a manifold. The manifold is configured to receive a plurality of tubes. The manifold is further configured to define a first volume that is part of the first circuit and a second volume that is part of the second circuit. The manifold includes three or more separators interposed between the first volume and the second volume to segregate refrigerant in the first circuit from refrigerant in the second circuit.

Abstract: A mattress showroom display device for a mattress, headboard or pillow presents selectively changeable product information regarding the mattress. The display device comprises a separate panel of such size and shape as to cover at least a portion of a surface of the mattress, headboard, or pillow. The display device includes a media display in the form of an area of programmable light emitting units associated with the separate panel for presenting the selectively changeable visual product information regarding the mattress. The media display has the capability to electronically connect to a power source and the programmable product information control source.

Abstract: A mechanical fluid separator defines an interior chamber for centrifugally separating entrained media from a fluid stream. The mechanical fluid separator has a fluid inlet connecting the interior chamber with a media entrained fluid source. A cone shaped baffle disposed within the mechanical fluid separator defines a conical surface having a concave surface and a convex surface. The conical surface has an annular base side and an annular apex side. The base side terminates in a circumferential rim contacting the annular chamber surface above the fluid inlet and said apex side terminates in an apex annular hole. The fluid stream is centrifugally directed in a first direction about the annular chamber surface and the convex surface of the conical baffle to disentrain the entrained media from the fluid stream. The disentrained fluid stream then passes through a window in the cone shaped baffle and escapes through a fluid outlet.

Abstract: A combined mode and temperature control valve for an HVAC housing includes a cylindrical sleeve rotatable within a stationary barrel. Hot or cold air enters lengthwise inlet slots in one side of the barrel located below or above a stationary dividing baffle in the housing. Air entering the barrel can exit to either a heater outlet, defroster outlet, or A/C outlet. The sleeve includes slots and openings which, when rotated continuously through a predetermined increment, open and close the hot and cold inlets in complementary fashion to allow in a full temperature range of hot or cold air, which mixes inside the hollow cylinder. The sleeve opens only one outlet at a time, blocking the other two, over the increment of rotation.

Abstract: A serpentine heat exchanger tube structure is formed with spaces between opposite runs of the tube structure that are smaller than the fins which must be inserted into the spaces. The tube structure is pressed onto a series of spreader blades at a fin inserting station to spread the runs of the tube structure, the fins are loaded into a series of compartments of a shuttle at a remote fin loading station, the shuttle is moved to the fin inserting station to position the compartments opposite the respective spaces of the tube structure on the side of the tube structure opposite the side from which the spreader blades entered, and a series of insertion blades are moved into the compartments to move the fins out of the compartments and into the tube spaces as the spreader blades are simultaneously withdrawn.

Abstract: Flat tubing is fed from a continuous supply into an embossing station and then into a cutting station and is briefly stopped periodically for an operation in each station. The embossing station has embossing dies for forming a transverse groove in the tube where a cut is desired and for reducing the tube perimeter dimension adjacent the cut to a required size. At the cutting station grippers engage the tubing on either side of the groove and bend the tubing to separate it at the groove.

Abstract: An apparatus sizes tubing, and positions and installs a manifold for single or multi-pass heat exchangers. Tubing is provided which has at least one first end and at least one second end. The first end is sized to a first desired perimeter dimension and, simultaneously, a first manifold is positioned and installed which has a first opening for receiving the first end of the tubing. Additionally, the second end is sized to a second desired perimeter dimension and, simultaneously, a second manifold is positioned and installed which has a second opening for receiving the second end of the tubing. A positioning control aids in the insertion of the ends into the manifolds to the desired depth or pressure. The apparatus is capable of sizing tubing, and positioning and installing manifolds for single or multi-pass heat exchangers having variously dimensioned tubing. The present invention also provides for a method of sizing tubing, and positioning and installing manifolds.

Abstract: Serpentine heat exchanger tubes are formed with spaces smaller than the fins which must fit in the spaces, the tubes are elastically spread apart so that tubes can be inserted, and the tubes are then allowed to contract to grip the elements for good contact and to help maintain the assembly until a brazing operation. A machine for inserting the fins has spreader blades for insertion into the tube spaces remote from the tube bends, and including sets of blades which then are moved toward the bends to fully dilate the spaces to permit easy insertion of the fins.
