Abstract: A system and method of additive manufacturing. A first layer having a first outer periphery is formed by extruding from a nozzle the material in a first spiral pattern extending from a starting point located on the first outer periphery toward a center of the first layer. When an inner limit is reached, a second layer having a second outer periphery is formed on the first layer by extruding the material from the nozzle in a second spiral pattern extending from the inner limit to the second outer periphery.

Abstract: A composition containing a quaternary organosilane foaming agent capable of foaming various liquids in order to remove the liquids from subterranean wells is described. For instance, the composition can be used to remove hydrocarbon condensate liquids from a gas well or an oil well. Of particular advantage, the composition can foam liquids containing substantial amounts of hydrocarbons.

Abstract: An automated ordering system for consumables, equipment maintenance supplies, and the like. The present invention uniquely combines the features of instrument maintenance and sample tracking systems with unique e-commerce and order generation systems. In doing so it provides unique advantages to both vendors and users. An aspect of the present invention is “permission purchasing” in which, through the use of the system, a user is supplied with all the parts and services needed to maintain a piece of equipment. In some embodiments, orders are generated using a data set with information specific to a particular instrument and responsive to the usage of the instrument. The system optionally makes use of computer networks such as the Internet.

Abstract: A content-aware flow switch intercepts a client content request in an IP network, and transparently directs the content request to a best-fit server. The best-fit server is chosen based on the type of content requested, the quality of service requirements implied by the content request, the degree of load on available servers, network congestion information, and the proximity of the client to available servers. The flow switch detects client-server flows based on the arrival of TCP SYNs and/or HTTP GETs from the client. The flow switch implicitly deduces the quality of service requirements of a flow based on the content of the flow. The flow switch also provides the functionality of multiple physical web servers on a single web server in a way that is transparent to the client, through the use of virtual web hosts and flow pipes.

Abstract: Novel methods for monitoring and recording fouling of aqueous systems are disclosed. The methods employ a heat transfer test assembly including an outer tube member, a heating rod positioned within the outer tube member, a ribbed tube sleeve fitted over the heating rod and thermocouples for sensing the wall temperature of heating rod. The heat transfer test assembly is connected to a monitoring and recording assembly that is connected to or includes a piping assembly. The piping assembly and the heat transfer test assembly are placed in fluid communication with a heat exchanger. Fouling determinations of fluid flowing through the piping assembly are made at varying flow rates with simultaneous monitoring and recording of the flow rates together with data, such as corrosion, pH, conductivity, and the like.

Abstract: This invention relates to a process for inhibiting the formation of biofilm and/or removing biofilm deposited on an enhanced tube of a heat exchanger in contact with an aqueous system. The process comprises feeding an oxidant selected from the group consisting of chlorine dioxide and stabilized bromine into an aqueous system such that the oxidant agent comes into contact with the enhanced tube.

Abstract: Various passive remote control devices are disclosed. These passive remote control devices may include one or more RFID tags and one or more switches. In various embodiments, the passive remote control devices include identity devices, financial devices remote controls, and the like. The devices controlled may include electronic devices, televisions, computers, locks, physical access systems, or the like. In some embodiments, switches are configured to enter data into a switchable RFID device, for example to select a financial account.

Abstract: Systems and methods of generating ions at atmospheric pressure are presented. These systems and methods include spatially dependent analysis of a sample using an effusive ionization source. Systems and methods of isolating samples at atmospheric pressure are presented. These systems and methods include using a barrier to prevent metastables or electrons from an effusive ion source from reaching a sample unless the sample is in an analysis position. Systems and methods of using metastables in collisionally induced dissociation are presented.
