Abstract: The system comprises a central processing module that is configured to interconnect the fresh departments and operational functions. These tasks can include facilitated order fulfillment, inventory and accounting functions, sanitation, maintenance, traceability and others. This is a system that integrates various sub-systems within the fresh departments, as well as integrating the fresh departments together. The system may also utilize a plurality of slicing machines that communicate with the centralized processing unit. The software modules resident in the processing unit receive inputs that represent customer orders, and dispatch these orders to the plurality of slicing machines. The slicing machines are in communication with the software modules such that the modules are aware of the food product that is currently placed on the slicer. In this way, the software modules are able to direct specific orders to a particular slicing machine, minimizing human interaction and customer wait time.

Abstract: A solid imaging apparatus is provided that includes a replaceable cartridge containing a source of build material and an extendable and retractable flexible transport film for transporting the build material layer-by-layer from the cartridge to the surface of a build in an image plane. An operator using the device needs merely to remove a spent cartridge and replace it with a fresh cartridge to continue solid imaging virtually uninterrupted. The apparatus also includes the capability of withdrawing and inserting an imager without the operator having to perform a separate alignment step. A brush attached to the transport film and forming part of the cartridge provides for intra-layer removal of excess uncured build material. If desired, the apparatus can produce a fully reacted build. A high intensity UV source cures the build between layers. An injection molded build pad is designed to hold a build in an inverted position for improving the build.

Abstract: A solid imaging apparatus and method employing a radiation transparent build material carrier and a build material dispensing system that accurately controls the thickness of the transferred layer of solidifiable liquid build material to the radiation transparent build material carrier to achieve high resolution imaging in three-dimensional objects built using an electro-optical radiation source.

Abstract: A disposable liquid build material feed cartridge for use in a solid imaging apparatus and a method of dispensing build material for use in such an apparatus with a radiation transparent build material carrier. The disposable liquid build material feed cartridge recovers unused liquid material from the radiation transparent build material carrier and recycles it through a filter into a supply reservoir for reuse. A dispersing roller is employed to express any entrapping air bubbles in the solidifiable liquid build material that is dispensed onto the radiation transparent build material carrier prior to its being imaged.

Abstract: A method and apparatus for making a foam-in-place cushion in which a foam-forming composition is dispensed between two plastic film portions in a predetermined fashion to selectively control the distribution of the foam in the cushion. A foam dispenser can be moved in a transverse direction as foam is dispensed. A dispersion device can be employed to apply pressure on predetermined areas of the film portions towards each other so as to cause the composition to be redistributed in position in a predetermined manner while the composition is in a less than fully expanded state. The plastic film can then be sealed closed to form an expanding foam cushion that can be placed into a shipping carton where the cushion expands to fill void space, or into a mold where the cushion expands and is molded into a desired shape.

Abstract: A molding system for foam-in-bag cushions comprises a mold defining a mold cavity, an air plenum separate from the mold cavity, a plurality of air passages that connect the mold cavity to the air plenum, and at least one port connected to the air plenum. The mold cavity has an open side and the mold includes a door that is movable between a closed position closing the open side of the mold cavity and an open position allowing a cushion to enter and exit through the open side. The system further comprises a pneumatic vacuum/blowout system connected with the at least one port. The vacuum/blowout system comprises a vacuum source, an air tank containing pressurized air, and a vacuum/blowout valve structured and arranged to alternately couple the at least one port either to the vacuum source or to the air tank.

Abstract: A heating element for a film-sealing apparatus comprises a heating wire segment formed of a first metal having a first reflectance to laser radiation of a predetermined wavelength. The heating element further comprises a first conductor lead comprising a wire having one end joined to a first end of the heating wire segment, and a second conductor lead comprising a wire having one end joined to a second end of the heating wire segment. The first and second conductor leads have a lower electrical resistance than the heating wire segment, and are formed of a second metal having a second reflectance to laser radiation of the predetermined wavelength, the second reflectance being higher than the first reflectance. Each of the first and second conductor leads is lap-welded to the respective end of the heating wire segment using laser radiation of the predetermined wavelength.

Abstract: A machine for severing a web, comprising a movable surface positioned such that the web may exert gravitational force against the movable surface, the movable surface providing frictional force against the web such that movement of the surface causes movement of the web, and a severing mechanism to sever the web into selected lengths, the severing mechanism including a severing device that urges the web against the movable surface to effect the severance of the web.

Abstract: An inflatable web, and method and apparatus for inflating the web, which generally includes two sheets having inner surfaces sealed to each other in a pattern defining a series of inflatable chambers of predetermined length, each of the chambers having at least one change in width over their length; an inflation port located at a proximal end of each chamber, the inflation ports being formed by intermittent seals between the sheets; and longitudinal flanges formed by a portion of each of the sheets that extend beyond the inflation ports and intermittent seals.

Abstract: An apparatus and a method for inflating an inflatable web in which, in one embodiment, the inflatable web is conveyed along a path of travel with an inflation element positioned between unsealed edges of the web and proximate the inflation ports of the web's inflatable chambers, and a tracking sensor is used to detect the transverse position of the web with respect to the inflation element. A web tracking system is employed to continually adjust the transverse position of the web to maintain it within a predetermined range with respect to the inflation element. In this manner, the consistency of inflation of the inflatable chambers is improved.

Abstract: A solid imaging apparatus and method employing build material transfer means effective to transfer solidifiable liquid build material from a first side of a radiation transparent build material carrier to a receiving substrate without entrapping air bubbles in layers of transferred solidifiable liquid build material and to cleanly separate the solidified build material from the radiation transparent build material carrier as each layer is formed during the layerwise building of a three-dimensional object. An expandable membrane forming an arcuate dome and a reciprocatible flexible film are employed to effect transfer of the solidifiable liquid build material.

Abstract: A solid imaging apparatus and method employing sub-pixel shifting in multiple exposures of the digitally light projected image of a cross-section of a three-dimensional object on a solidifiable liquid medium. The multiple exposures provide increased resolution, preserving image features in a three-dimensional object and smoothing out rough or uneven edges that would otherwise be occur using digital light projectors that are limited by the number of pixels in an image projected over the size of the image. Algorithms are used to select pixels to be illuminated within the boundary of each image projected in the cross-section being exposed.

Abstract: A mixing chamber assembly which has a reciprocating rod (270) received within a mixing chamber of a mixing chamber member (28). The reciprocating rod (270) is in a non-interference position with the mixing chamber over its entire length within the mixing chamber. The non-interference fit provides for continuous solvent flow about the exterior of the rod and interior of the wall defining the mixing chamber such that solvent drips out the discharge end of the mixing chamber and the rod is free to float or ride on a film of solvent. The ability for the rod to ride on a film of solvent over the entire portion received within the mixing chamber, allows for a much reduced reciprocating motive force requirement and a corresponding freedom to increase the mixing chamber volume.
