Abstract: A powder mixing system (12) includes a conduit (40) having a first end and an opposing second end, the conduit bounding a passage; a fluid pump (80) fluid coupled with the conduit, the fluid pump being configured to pump a liquid through the passage of the conduit; and a tubular transfer member (190) in fluid communication with the conduit, the transfer member being configured to couple with a powder bag housing a powder. The mixing system further including: (1) an eductor coupled to the transfer member and disposed in-line with the conduit so that the liquid pumped through the conduit also passes through the eductor; and/or (2) an auger assembly comprising an auger blade, at least a portion of the auger assembly being rotatably disposed within the transfer member.

Abstract: A method of installing a flexible bioprocess container in a bioprocessing system having a rigid housing with an interior compartment and extending between a top and an opposing base. The method includes coupling a first surface of the flexible bioprocess container to a moveable platform positioned within the interior compartment of the rigid housing; coupling a second surface of the flexible bioprocess container to the base of the rigid housing; and moving the movable platform relative to the rigid housing and toward the top of the rigid housing so as to at least partially expand the flexible bioprocess container within the interior compartment of the rigid housing.

Abstract: The present set of embodiments relate a system, method, and various devices for installation of a bioproduction system. The bioproduction system includes a rigid housing having a moveable platform to assist in the installation of a bioprocessing container within. The system also includes mounting systems for a variety of peripherals originating from the flexible container while safeguarding operators. More specifically, the system includes systems and methods for mounting bearings, organizing tube sets, and placement of the flexible container in its proper orientation.

Abstract: A photovoltaic crucible mold release compound includes a powder mixture comprising silicon nitride powder having 1 ppm of impurities or less and silicon dioxide 1 ppm of impurities or less mixed in with the silicon nitride powder until the gray of the silicon nitride powder turns lighter in color which is from 1% silicon dioxide in weight up to 50% silicon dioxide in weight. Also included is a binder having a liquid. The powder mixture is mixed with the binder. The binder can be ethanol, water or alcohol. A photovoltaic crucible mold release compound can also include a photovoltaic crucible mold, so that the mold release compound is applied to an inside surface of the photovoltaic crucible mold to a thickness of 75 to 1500 microns.

Abstract: A method of marketing includes the steps of: fabricating an air pillow having a top layer, one or more intermediate layers and a bottom layer; heat laminating the top layer to the one or more intermediate layers and heat laminating the bottom layer to the one or more intermediate layers; printing advertising on a first top sheet of the air pillow; forming a one-way valve on the air pillow, and distributing the air pillow as package packing material. The one-way valve is formed by and between the top layer and the bottom layer. Preferably, a plurality of micro air pockets are formed in the intermediate sheet. Optionally, the air pillow can be formed as a plurality of air cells, and a column of logos can be printed on each of the plurality of air cells.

Abstract: A photovoltaic attachment system for mounting photovoltaic panels on top of a building's roof is disclosed. The attachment system does not require drilling of holes into the roof and does not affect the integrity of the roof. The photovoltaic attachment system comprises of a grid of photovoltaic panels mounted on top of beams that are attached to the walls around the roof. The roof structure is not affected. No holes are drilled into or through the roof and no leakage of water through the roof will result from the mounting of the photovoltaic panels.

Abstract: A passive convection cooling system for photovoltaic panels utilizing principles of aerodynamics to channel natural air flow under the photovoltaic panels and to increase the rate of heat transfer to greatly increase the convection rate and decrease the temperature of the photovoltaic panels thereby increasing the efficiency of the solar cells and decreasing failures of the photovoltaic system is disclosed. The photovoltaic cooling system comprises of multiple members arranged in predetermined configurations and affixed under the photovoltaic panel to direct natural air flow, according to aerodynamic principles, to increase rate of heat transfer under the photovoltaic panel to greatly increase the convection rate to effectively cool the photovoltaic system.

Abstract: A routing engine for a node controller of a switch or for a router provides enhanced routing for unicast and multicast connections by representing preferred routing trees, associated with different bandwidths and quality of service indications, as tables having, for each entry, a node identification, a parent node identification, a link identifier and ah effective distance by which a node identified by the node identification is separated from the controller or router. The routing engine adapts quickly to changes in network configurations, such as link failure, by quickly patching a table affected by the failure in order to maintain service until a new preferred routing tree can be calculated. Recalculations of preferred routing trees are avoided by using said table to determine whether a new link or a restored link could possibly provide a more cost effective route than that specified in the existing table.

Abstract: In a communication network having a set of hosts and switch based label swapping communication nodes, each node has a control processor that is also a host that sends and receives messages via the switching apparatus in its associated node. At least one of the hosts includes a distribution tree set up procedure. That procedure stores source and destination data designating a set of source hosts and a set of destination hosts in the communication network, and defines a distribution tree of virtual connections. The designated source hosts and destination hosts may include the control processors of some or all the network nodes. The defined virtual connections include a virtual connection from each designated source host to all of the designated destination hosts, and message labels for all messages sent by the source hosts to be routed to the destination nodes.
