Abstract: The invention relates to a method and system for monitoring tray activity in which a tray sensing device detects the presence of a tray in a given location. The tray can be a conventional tray for supporting food articles or can be supported or integral with a food cart. Information from the tray sensing device can be forwarded to a central information system. The central information system can display the information or activate an alarm. The alarm can be an audio or visual alert. The alarm can be deactivated upon removal of the tray from the given location or upon dispatching of personnel to the given location.

Abstract: Desalination apparatus based on porous restraint panels fabricated from a number of different layers of metal, thermoplastic, or other substances are used as sophisticated heat exchangers to control the growth of gas hydrate. The gas hydrate is produced after infusion of liquid hydrate-forming material into water to be treated, which liquid hydrate-forming material can also be used to carry out all the refrigeration necessary to cool seawater to near the point of hydrate formation and to cool the porous restraint panels. Hydrate forms on and dissociates through the porous restraints. The composite restraint panels can also be used in gaseous atmospheres where, for instance, it is desired to remove dissolved water.

Abstract: A quick connector coupling comprising a connector body, a tubular male member with an upset, a primary retainer and a separate redundant latch/verifier. The connector body defines a through bore and the male member extends into the bore. The primary retainer releasably secures the male member within the connector body. The redundant latch/verifier is releasably coupled to the connector body and movable between an unlatched position and a latched position. It includes spaced apart fingers with verifying tabs that permit movement to the latched position only after full insertion of the male member. The fingers have release tabs to manually spread the extension beams. In another form, the connector body includes locking pads extending radially inward. The legs of the primary retainer are located inward of the locking pads preventing the legs from moving to a released position if said male member is pulled in a direction to remove it from the connector body.

Abstract: A method includes the steps of connecting the input of a compressor of a vehicle air braking system with a gas output of a crankcase of a vehicle engine, directing into the input of the compressor a blend of from 0% crankcase gases and 100% ambient pressure air to 100% crankcase gases and 0% ambient pressure air. The blend of gases may be filtered upstream of the compressor.

Abstract: A multi-layer patient support element comprising at least one structural member, wherein the structural member has a top surface and a bottom surface and wherein the top surface comprises a low radiation absorbing separation member. The support element of the present invention can be integrated into a patient support surface, used as an insert or easily removable from the patient support surface. The support element can reduce or eliminate radiation skin burn caused during radiation therapy.

Abstract: Underlying surface lift systems and methods are disclosed that facilitate the lifting and moving of constructions, including but not limited to structures, and machines, implements, building materials, earth, rock, and other massive massively weighted and/or large dimensioned objects or materials. The underlying surface lift systems and methods may be used or performed in combination with one or more support elements to the construction or other item to be lifted, such as steel I-beams or wooden beams or other supportive elements. The invention comprises in some embodiments underlying surface lift systems and methods, alone or in combination with or performed with supportive elements generally, such as beams and other devices or elements. Further embodiments may include an underlying surface lift apparatus having a support plate and a lift device in adjustable connection with the support plate. In some embodiments a pivot saddle is the adjustable connection of the support plate and the lift device.

Abstract: A multiple access scheme is described. A first bit stream is scrambled from a first terminal according to a first scrambling signature. A second bit stream is scrambled from a second terminal according to a second scrambling signature, wherein the first bit stream and the second bit stream are encoded using a low rate code. The first scrambling signature and the second scrambling signature are assigned, respectively, to the first terminal and the second terminal to provide a multiple access scheme.

Abstract: A collapsible self-supporting structure used in combination with an improved articulating hub assembly. The articulating hub assembly is used as a connector among tubular rod elements which together provide a generally tubular frame matrix used to erect a collapsible self-supporting prefabricated deployable structure where a clear span interior without supporting columns is required.

Abstract: Smart, rollable, mini-pallet cargo container system comprising robust, auditable, secure, sealable, lockable, trackable and pollable, universal, half/quarter-sized boxes particularly useful for moving highly valuable or sensitive, personal, political, military or commercial materials, embodiments include truly verifiable ballot boxes, verifiably secure moving containers. Blast attenuation inserts are disclosed. The boxes include electronic locks containing event memory, sensors and alarms, and RF communications and GPS locator module(s) that radio to a base station the time, location and status of the inventive box, and anomalous events as they occur, including unauthorized attempts to open or break into the container, or potential damage events. In addition, both the locks and comm modules are programmable, and provide extensive, and selectably pollable and down-loadable, printable event, access and transport history and audit trails.

Abstract: A quick connector coupling assembly to connect a rigid tube to a hollow body component. A retainer releasably retains the tube within a bore in the body. A resilient seal member surrounds the tube and creates a fluid tight seal against the tube and the body defining the bore. A sleeve extends between the seal member and the retainer and transfers axial load on the seal due to pressure to the retainer. In one embodiment a Teflon spacer is interposed between the seal member and the sleeve. A stuffer pin preassembles the sealing and retention elements for insertion into the connector body.

Abstract: The invention relates to the use of used alumina to reduce the level of inorganic contaminants, such as mercury and arsenic, from waste fluid streams. The invention further provides a process for reducing the level of mercury or arsenic in fluid streams by contacting the fluid stream with used alumina, such as used Claus catalyst.

Abstract: A carton for enclosing cylindrical articles includes a dispenser that provides access to at least two endmost articles in an uppermost row, and to at least one article in a lowermost row, when fully loaded. The dispenser is defined by contiguous severance lines that extend across the top wall, side walls, and end wall. The dispenser is opened by tearing the severance lines to define a stopper wall and as a recess in each side wall that, at its lowest point, is spaced at a distance above the bottom wall less than half the height of the carton, with the dimensions and position of the recess being sufficient to expose at least part of the ends of one or more lowermost articles. Each side wall severance line meets the end wall severance line at a distance above the bottom wall no less than half the height of the carton.

Abstract: Devices for reduction of damage from friction and for prevention and treatment of skin breakdown by relief of friction and shear forces. A friction reducing device may include a pair of thin membranes with low coefficients of friction with respect to each other, and of which one is free to slide through a limited distance along the other. A method of making one such device includes forming a dome in a flexible film and adhesively attaching a skirt surrounding the dome to a skin contact layer. Similar friction reducing devices may be incorporated in shoes, other clothing, or sports equipment or used to protect movable rods or cables.
