Abstract: A package labeling system for applying an adhesively backed label, which is received from a label transport, preferably to the bottom of a package through a label application opening in the package support, includes an applicator body and a suction tube extending through the applicator body and defining a suction opening above the body. A label supporting plate is positioned above the applicator body and pivotally mounted thereon. The plate defines a suction tube aperture and is pivotable from a horizontal position in which the suction opening is positioned within the aperture to inclined positions in which the aperture is raised above the suction opening. A spring urges the plate into its horizontal position and a partial vacuum is applied to the suction tube. A means for moving the applicator between a first position, adjacent the label transport, and a second position, is provided.

Abstract: A low wash and rinse temperature (120.degree.-140.degree. F.) warewasher accomplishes the same general washing and rinsing effectiveness as a conventional high temperature (150.degree. F. minimum wash, 180.degree. F. minimum rinse) warewasher without loss of productivity resulting from time lost between completion of washing and commencement of rinsing a given load of ware, through use of independent, dedicated wash and rinse systems, the latter of which includes a holding tank which enables independent batching of a predetermined volume of rinse solution from properly-proportioned fresh water and sanitizing agent while washing a given load of ware. The sanitizing agent is introduced independently into the holding tank and independently of the fresh water line, and is therefore unaffected by a great range of water line pressures and the mineral conditions of the water.

Abstract: Delivery of a chemical sanitizing agent to the rinse system of a warewasher is confirmed by first sensing the absence and subsequently the presence of the sanitizing agent near the outlet of the delivery conduit. Failure to meet these two conditions in this order and within a preset time triggers an alarm to indicate delivery failure.

Abstract: An insulated door for refrigerators, freezers or similar cabinets where the inner and outer door surfaces are normally subjected to substantially different temperatures. The main door components, the door face and drum, are interconnected without the use of threaded fasteners such as screws or bolts. Instead a hardened, foamed in situ insulating material forms the main interconnection between the door face and drum, securing them together but yet accommodating thermally induced, relative movement between the two components. In constructing the door S-shaped retainers are used which receive in their oppositely opening loops the edges of the face and drum. Temporary spacers are then interposed between the face and drum edges for the foaming operation.

Abstract: Processing of certain foodstuffs in a high speed food processing apparatus is facilitated through the use of a flexible, non-ductile food basket, the shape of which is restored by the bowl when the basket is inserted into the bowl.

Abstract: Plural printing stations are located wherever convenient within a printing machine for pressure sensitive labels. Each label is individually printed at each station by detaching the label from its release web after each printing operation, advancing the label, and reattaching the label to a different portion of the web prior to the next printing operation.

Abstract: The lid support member for the lid of a high speed food processing apparatus supports a mixing baffle blade through the center of the lid. The mixing baffle blade and its rotatable support are counterbalanced to help prevent the mixing baffle blade from freely rotating when its axis of rotation is not vertical.

Abstract: An improved insulated cabinet, such as a refrigerator or freezer cabinet, is constructed by first manfuacturing a rigid structural frame to close tolerances and then loosely attaching the remaining components of the outer shell of the cabinet by mechanical connections which permit some relative movement between the main frame and the other outer shell components. The outer shell, with an innershell positioned within it in spaced relationship to define an insulating cavity, is then placed in a jig which positions precisely the components of the outer shell in their desired final relationship. The loose connections between the outer shell components permit them to be shifted by the contacting surfaces of the jig into the precise relative positions desired, and while the outer shell components are so supported by the jig, a hardenable insulating material is introduced into the cavity, where, upon hardening, it fixes the outer shell components and the inner shell in their desired positions relative to each other.

Abstract: The lid support member for the lid of a high speed food processing apparatus supports a mixing baffle blade through the center of the lid. The mixing baffle blade drive shaft is hollow for introducing liquids into the mixing bowl directly over the food processing blades.

Abstract: The center portion of the lid for a high speed food processing apparatus is flexible, preferably transparent and is supported by a rigid lid support member. The outer portion of the lid is stiff so that the center portion acts as a spring when compressed by the support member onto the edge of the bowl of the food processing apparatus.

Abstract: A pressure vessel such as a steam cooker is provided with a door closure comprising a horizontally disposed door mounting and actuating member pivotally mounted for swinging movement across an access opening of the vessel and supporting a warped door for movement into and out of the opening; a rotationally and axially movable shaft carried in the door mounting member has a cam and follower associated therewith for moving the shaft axially in response to rotation thereof; and mechanism coupling the door and the shaft for shifting the door laterally with respect to the door mounting member also causes translational movement of the door toward and away from the door mounting member in response to rotation of the shaft so that the door can be inserted through the opening in a warped condition and then unwarped so that the outer peripheral edge sealingly engages the inside of the opening. The operating handle for the actuating mechanism is located to one side of the access opening when the door is closed.

Abstract: A dishwashing machine has a tank defining a cleansing chamber, a rack within the chamber having a bottom and parallel sides and elongated tracks extend between the sides of the rack and the chamber side walls. Each track includes longitudinally extending guideways, one on each side of the track. Rollers mounted on the tank side walls are received within one guideway of each track, and rollers mounted on each side of said rack are received within the other guideway of the corresponding track. A bumper member mounted on each end of each said track has a retaining tab formed as an integral extension to the bumper member, and a lock part on the tab is engaged through a hole in the track. A retaining pin extends through the ends of the track and through the bumper member. The pin has a head preventing the pin from passing completely through the track and the tab extends over the head of the pin.

Abstract: The recirculating pump output is monitored as the pump is operated during each fill cycle, and the fill is terminated just when the desired pump output is reached. The output is less than the pump maximum and results from continuous aspiration of water and air into the pump inlet, thus using only the minimum liquid necessary, and automatically reducing liquid consumption during subsequent fills as the washing operation progresses. The pump inlet faces downwardly at the bottom of the dishwasher tank to control surging.

Abstract: Disclosed is a computing scale system utilizing an integrated circuit microcomputer for computing the value of a product being weighed and for controlling the operation of a label printer associated therewith. The microcomputer operates with 4-bit words, and there is provided a multiplexing network for multiplexing weight, price, and status information into the microcomputer. Weight readings are made by a bank of photosensors, which read the position of a chart moveable in response to weight on the scale platter. Means are provided for performing a parity check on the data read by the weight photocells, and the data so read is converted from Gray code to BCD code by a table lookup routine. The scale system may print labels having weight and computed value, zero weight and fixed value, or weight and fixed value. The scale has both selectable price and weight dead zone capability with adjustable range. There is a motion detection routine employing a variable settling time.

Abstract: A dishwasher has a cabinet which defines a cavity, an access opening into the cavity, and a door for said opening. A washing fluid reservoir in the cabinet beneath the cavity holds washing fluid for the dishwasher. A drain for the washing fluid reservoir is manually operable between open and closed conditions when the door is open. The drain is also interlocked with a door on the cabinet which covers the access opening such that when the door is closed, the drain, if previously open, is automatically moved to its closed condition to ready the reservoir for filling. Thus, attempting to fill the reservoir with the drain open will be effectively prevented.

Abstract: The drain filter has large inlet openings at a raised position and small inlet openings at its bottom, all shaped to cooperate with the dishwashing machine sump to form labyrinthine drainage passageways to stop debris exceeding an acceptable size. The drain filter is in two parts, a fixed portion and a removable portion, both of which provide these features. The large inlet openings into the removable portion of the drain filter are upwardly facing and on the downstream side of an elevated wall which forms a dam to stop dense objects from entering the filter. The total filter inlet area is small to maintain a high flow velocity to float softer and lighter items over the dam for removal from the dishwasher when it is drained. The small inlet openings drain the remaining fluid after the level falls below the large openings.

Abstract: A rotating spray arm is supported by a removable and vertically adjustable upper rack of a dishwasher. The fluid coupling for the spray arm is not affected by changes in the upper rack vertical position. The spray arm is also protected by a guard which forms a stand for the rack when removed from the dishwasher.
