The present invention relates to a disposable conveyor for use with an apparatus handling contamination-sensitive discrete items. The conveyor has at least one cavity, each cavity capable to carry at least one discrete item. The conveyor is adapted to be mounted on the contamination-sensitive apparatus that, in operation, is capable to impart movement to the conveyor for displacing the conveyor, and its cavities, along a predetermined path. The present invention also relates to a method for transporting discrete items in a machine performing production runs with different types of contamination-sensitive discrete items. The method involves installing a conveyor as described above on the machine and using it to perform a first production run with a first type of discrete items. The conveyor is then disposed of and a new conveyor installed on the machine, used to perform a second production run with a second type of discrete items, different from the first type.

The present invention relates to a method of preparing a separation medium, which method comprises to provide a slurry of essentially spherical polymer beads in an aqueous solution of a natural polymer and contacting the slurry with an organic solvent in the presence of emulsifier to allow aggregation of the beads. In a preferred embodiment, the natural polymer is agarose. The present invention also encompasses a separation medium comprised of one or more aggregates, wherein each aggregate comprises a plurality of porous and essentially spherical polymer beads assembled by a porous gel.

A method and system for submitting ratings for wireless device applications directly from a wireless device is disclosed. An option to submit a rating for a wireless device application is displayed on the wireless device. When a user selects this option, and the wireless device receives a rating, this rating is sent to a back-end server, along with a unique identifier for the wireless device and the application identifier. This rating is then stored in a database at the server. In this manner, ratings can be submitted directly from the wireless device. In addition, one rating for each wireless device application is stored for each wireless device. A user may submit multiple ratings for the same application on the wireless device, but only the most recent rating is stored.

A method for handling messages between wireless devices in a network, includes: receiving a message for a device application by a dispatcher application on a receiving wireless device; determining that the device application does not exist on the receiving wireless device by the dispatcher application; and sending a notification to a user of the receiving wireless device of receipt of the message. Because the dispatcher application on the receiving wireless device sends this notification, the developer of the device application has an opportunity to sell the device application to the user, and the user has the opportunity to purchase the device application.

The present invention relates to a process for producing high purity lithium hydroxide monohydrate, comprising following steps: concentrating a lithium containing brine; purifying the brine to remove or to reduce the concentrations of ions other than lithium; adjusting the pH of the brine to about 10.5 to 11 to further remove cations other than lithium, if necessary; neutralizing the brine with acid; purifying the brine to reduce the total concentration of calcium and magnesium to less than 150 ppb via ion exchange; electrolyzing the brine to generate a lithium hydroxide solution containing less than 150 ppb total calcium and magnesium, with chlorine and hydrogen gas as byproducts; producing hydrochloric acid via combustion of the chlorine gas with excess hydrogen and subsequent scrubbing of the resultant gas stream with purified water, if elected to do so; and concentrating and crystallizing the lithium hydroxide solution to produce lithium hydroxide monohydrate crystals.

The present invention relates to a method of preparing an insoluble separation matrix, which method comprises salt-treatment of a polysaccharide gel followed by cross-linking of the polysaccharide polymers. In one embodiment, the method comprises providing an aqueous solution of a gelatable native polysaccharide; lowering the temperature of the polysaccharide solution to a value below its gelling point; salt-treatment by adding at least one salt to the resulting polysaccharide; and cross-linking the salt-treated polysaccharide. The polysaccharide may be prepared e.g. into particles, membranes or monoliths.

This invention is directed to systems and methods for preserving delivery status notification information as a message transits from one type of network to another type of network. For incoming messages, the present invention takes a two-pronged approach whereby the delivery status notification information accompanying the incoming message is 1) mapped to the closest available options supported by the network and 2) preserved so that the original information may be fully recovered without loss at a later time. When messages are delivered within the network, the mapped delivery status notification information will generate the closest delivery status notifications supported by the network. For outgoing messages, the preserved delivery status notification information is extracted and used to set delivery status notification options. If the message is being transferred to the same type of network that originated the message, using the preserved delivery status notification information results in the original options being fully restored without loss of any kind. If the message is being sent to a different network than that generated the message, using the original delivery status notification information will result in the closest available options being selected. This two-pronged approach taken by the present invention minimizes the mapping losses under all circumstances.

The SMTP protocol takes a message formatted according to a defined internet standard and wraps the message in an envelope. The message and envelope are sent to servers for transfer through the Internet to their intended destination. The SMTP protocol strictly defines the information that is transferred in the envelope and the format of the message. There is thus a real possibility that when messages are transferred from one network into an SMTP network that information will either be lost or not transferred correctly. The present invention provides systems and methods that take advantage of defined mechanisms to extend the SMTP protocol in order to create the novel extension that allows the transfer of virtually any information after the envelope is transferred but before the message is transferred. The invention allows information usually contained in the message portion to be transferred in the envelope portion. The invention also allows the preservation and transfer of information that would otherwise be lost.
