Abstract: A mullion bar assembly having enhanced heat transfer barrier characteristics is disclosed wherein the liners defining the freezer and the fresh food compartments define non-magnetic gasket sealing surfaces against which the magnetic door gaskets seal. Since the liners are typically made of plastic material, permanent magnets are disposed behind the liners so as to attract the magnetic gasket seals into sealing contact with their respective non-magnetic sealing surfaces. The non-magnetic sealing surfaces are spaced apart and the mullion bar is located between them such that it extends between opposite sides of the refrigerator cabinet and only between the spaced apart, non-magnetic sealing surfaces. No part of the mullion bar is exposed to either the freezer compartment or the fresh food compartment.

Abstract: A convection air inlet and suds control device is provided for a dishwasher. The dishwasher has a washing chamber with a bottom wall, a chimney extending through the bottom wall with opposite upper and lower ends positioned on opposite sides of the bottom wall. A chimney cap is spaced in covering relation over the upper end of the chimney. A container having an inner cup and an outer cup is mounted adjacent the bottom wall such that the inner cup surrounds the lower extension of the chimney. The outer cup includes an opening such that air may flow by convection into the outer cup, into the inner cup and upwardly through the chimney into the washing chamber so as to dry the articles in the dishwasher. In oversudsing conditions, the suds flow downwardly through the chimney for collection in the inner cup. Excess suds filling the inner cup will spill over into the outer cup. The inner cup and lower extension of the chimney cooperate to function as a valve.

A retainer stud has a plurality of cantilevered spring arms which are inserted into a tapered sleeve within the lower end of the upper coupling member so as to retain the two together and so as to permit the rotatable mounting of the spray arm within the dishwasher.

Abstract: An adjustable rinse additive dispenser is provided for a dishwasher having a washing compartment and a door pivotal between a horizontal open position and a vertical closed position. The dispenser includes a rinse additive reservoir mounted on the door. A conduit provides a fill opening for adding rinse additive to the reservoir. A knob assembly includes a shaft extending into the conduit so as to substantially seal the opposite ends of the conduit, and defines an annular chamber within the conduit. A trough is provided in the reservoir for holding a fixed quantity of rinse additive. A passageway provides communication between the trough and the annular chamber, and is normally closed by a plunger assembly. During the last rinse cycle of the dishwasher, the plunger assembly is moved to an open position so as to allow rinse additive to flow from the trough into the annular chamber.

Abstract: A fabric dryer includes a front bulkhead assembly providing a pair of airflow outlets from the drying chamber. A first airflow outlet is associated with the stationary front bulkhead adjacent the access opening of the fabric dryer. A second airflow outlet is integral with the lint filter and is located within an airflow space formed between the access opening and a projecting portion of the access door. The projecting portion of the access door generally overlies the second airflow outlet to protect the outlet from blockage by fabrics being tumbled.

Abstract: A refrigerated appliance for use as a salad bar includes an enclosure having a refrigeration unit mounted therein and a cooled food storage compartment. An upper wall of the storage compartment is provided with openings for receiving a plurality of foodstuff containers having bottom wall surfaces which extend into the compartment. An air inlet opening from the refrigeration unit is disposed proximate to the upper wall of the compartment and cool air issuing therefrom is directed at the exposed wall surfaces of the containers. To concentrate the air flow at the containers a duct surrounds the air inlet opening and is spaced closely from the containers. A free end of the duct is open to the storage compartment for circulation of the air through the compartment.

Abstract: A water delivery machine for delivering water under pressure from a pressurized main line to a linear irrigation system, the main line having spaced risers therealong, and wherein the water is delivered continuously as the linear system moves over the field being irrigated. The machine has fore and aft articulated booms, the inner ends of which are connected to the water conduit of the linear system, and the outer ends of which are connected to couplers. The booms provide water conduits to deliver water from the couplers to the linear system. Each boom includes a conduit section extending generally in the direction of travel of the linear system which is supported on a wheeled cart having inner and outer wheel bogeys.

Abstract: A method for determining macromolecules in polyacrylamide gels comprises forming a latent stain image by nucleating the gel with a palladium tetramine salt and developing the latent stain image by treating the gel with a physical developing solution comprising dimethylamine borane and a member selected from the group consisting of a transition metal salt and a tetrazolium salt.

Abstract: A self steering blade guide for a band saw, including a support block which can be rigidly fixed to the frame structure adjacent the blade and which supports a steering block having a blade receiving slot with side surfaces adjacent the flat sides of the blade and engagable therewith upon the sideways deflection of the blade, and a mounting connection between the steering block and the support block for permitting pivotal movement of the steering block about an axis parallel to the direction of travel of the blade, the axis being adjacent to or forward of the cutting edge so that the blade will pivot about the axis with the steering block when deflected, and through action on the blade by the material being cut the blade will automatically be returned to its normal position parallel to the direction of feed of the material through the blade.

Abstract: A tension adjustment for a band saw having a band saw blade (30) encircling upper and lower band wheels (26, 28) disposed on opposite sides of the cutting table (12), with the lower band wheel (28) and the drive motor (66) being supported by a housing (50) which is pivotally mounted to the frame structure (10) of the band saw and which can be moved toward and away from the upper band wheel (26) by means of a threaded rod (84) extending between the frame (10) and the housing (50) so that the tension in the band saw blade can be adjusted by pivotal movement of the housing (50) supporting the lower band wheel (28).

Abstract: In a band saw (10) particularly adapted for cutting meat, blade scrapers (25, 26) remove debris from the band saw blade (18) and throw it laterally and forward of the blade (18) into an enclosure (40), which can be removed without the use of tools for cleaning and for disposing of the collected debris. The location of the blade scrapers (25, 26) is slaved to the location of the saw blade (18) to automatically maintain the proper relationship for most efficient debris removal without adjustment.
