Abstract: A food package for sliced food products to be maintained with a fluffed appearance, the package including a base member forming a compartment for receiving the food product and a lid sealed to the compartment. The base member has a gripping portion and the lid has a tab which overlies the gripping portion when the lid is connected to the base member. In one form, the gripping portion of the base member has a plurality of edges that define an outer profile of the gripping portion and expose a portion of a lower surface of the tab. The outer profile limits tacking of the tab to the gripping portion when the lid and base member are cut from respective webs of material. Additionally, a method is provided for assembling a food container.

Abstract: A method of retracting a filmstrip wound on a filmstrip reel. The filmstrip has a rear end which is attached to a spool of a film cartridge. The filmstrip reel comprising a pair of side walls, each side wall having a spiral track for retaining an edge of the filmstrip. The filmstrip is rewound into the film cartridge by applying a removing force on the rear end of the filmstrip in a direction for rewinding the filmstrip into the films cartridge. At the same time, one of the side walls is oscillated with respect to the other side wall about its central axis.

Abstract: The present invention provides a method for correcting the density nonuniformities that occur down the page of a thermally printed document by providing a correction component, representing heating pulses, to each thermal printing element as a function of the line on which the thermal printer is printing. The correction component is determined from the product of a correction factor times the logarithm of the total number of lines to be printed divided by the number of the line next to be printed. The correction factor is calculated from the average number of heat pulses to be applied across the head at any time, or as a compromise a single number may be selected.

Abstract: A method and apparatus of the present invention corrects the nonuniformity in the printing density between the printing elements of a thermal print head by first printing across a transparent receiver with each element of the head activated with equal inputs (flat field). The print transmittance values are read from the transparent receiver using, for example, a microdensitometer, and an adjustment factor for each heating element is computed and maintained in storage to be combined with the number of heating pulses assigned to each of the respective heating elements as they perform their normal printing function.

Abstract: A cleaning device for a rail over which a conveyor or trolley system runs. The device comprises a pair of biased arm members, each arm member having a plurality of brush assemblies adapted to contact various portions of the conveyor rail.

Abstract: A fluid applying system in which a substantial portion of the componentry surface area of a conveyor system is sprayed with a fluid in a spray chamber and any excess or overspray is passed to an evacuating chamber and filtering station where any fluid particles are removed, thereby protecting the surrounding environment from being contaminated with fluid.

Abstract: A lubricating device for delivering multiple clean shots of lubricant to a moving conveyor or the like, comprises an electric motor, a positive displacement lubricant pump having a plurality of individual cylinders and associated pistons driven by a common shaft, a single revolution clutch coupling the output of the motor to the shaft of the lubricant dispenser, and a sensing and control system actuated by the moving conveyor which at an appropriate time causes the clutch to engage the motor to the shaft of the lubricant pump for a single revolution, causing the ejection of a plurality of individual clean shots of lubricant which are directed to selected portions of the conveyor system by individual conduits.
