Abstract: Systems for oxygen concentration and pressurization. An assembly includes a counterflow heat exchanger comprising a sidewall that defines a hollow cylindrical geometry, and an electrochemical assembly comprising a plurality of ceramic cells, wherein the electrochemical assembly is disposed within an interior of the hollow cylindrical geometry of the counterflow heat exchanger. The assembly is such that the electrochemical assembly receives an input gas comprising oxygen that is heated when passing through an input fluid flow path of the counterflow heat exchanger. The assembly is such that the electrochemical assembly outputs an oxygen-deficient output gas that is cooled when passing through an output fluid flow path of the counterflow heat exchanger.

The system includes a second stage oxygen concentrator comprising a second electrochemical stack, wherein the second stage oxygen concentrator receives the first oxygen output gas and outputs a second oxygen output gas. The first oxygen output gas is stored at a first storage pressure up to a first maximum pressure, the second oxygen output gas is stored at a second storage pressure up to a second maximum pressure, and the second maximum pressure is greater than the first maximum pressure.

Abstract: Extensions or additional software programs that are requested by a computer application running on an application platform are handled in an efficient manner by, among other things, regulating and tracking extensions that are downloaded. This allows the size of the application platform upon which the application is running to remain relatively small so as to mitigate strain on resources when the platform is initially deployed over a network (e.g., the Internet), thus making it easier and more likely for a user to install the application platform (and/or updates thereto). Requested extensions are subsequently added to and/or removed from the (already deployed) application platform based on, among other things, download metrics.

Abstract: A content delivery system stores large content as frames of video that can be served by content servers already optimized for streaming video. Instead of storing image tiles in separate files, the system treats each tile as a frame of a video and stores the tiles in a video format. This allows transfer of large data from a publisher to a content server by transferring a single file or a small handful of files (rather than thousands or millions of files). Web servers such as MICROSOFT Internet Information Server (IIS) include smooth streaming support that can return individual images as video frames as though the images were stored in separate files. Thus, the content delivery system provides easier management of large data for publishers while continuing to provide a smooth experience consuming the data for clients.

Abstract: The device is a seat trim heater. It employs electric infrared lamps to heat the seat trim before the trim is placed over the frame and cushion material of the seat. The device consists of a basic frame on which the trim is placed. The frame is made from a series of adjustable fabricated parts. Within this frame are infrared heaters and reflectors. The reflectors can direct the infrared heat both to the front and back so that the whole seat trim can be heated. Integral to the system is the control box that controls the heating of the seat trim. The seat trim heater uses instant on/off T-3 quartz lamps. The control box consists of a control panel that is NEMA rated, a disconnect switch, appropriate fusing, a SCR and appropriate circuitry. Further, the control panel allows the heat to be infinitely variable.

Abstract: A solenoid-actuated drain valve for a compressed gas reservoir of a diesel locomotive in which the valve element is a differential piston exposed on opposite faces to reservoir pressure for normally holding the valve closed and minimizing the opening force required to be exerted by the solenoid, a temperature-responsive heating element protects the valve against freezing, a sensing element senses accumulations of water from the compressed gas in the reservoir, and actuation of the heater and energizing of the solenoid for opening the valve are both controlled by a solid state circuit which prevents opening of the valve except when the sensing element senses accumulated water.

Abstract: Solenoid-actuated valve adapted for heavy duty use by having the coil of the solenoid divided into high and low power windings connected in and automatically energized in succession by a solid state control circuit for providing in sequence high power of predetermined short duration for opening the valve and low power of usually longer duration for holding the valve in open position.

An orifice and an equalizing valve in the upstream connection protect the tube against sudden overpressures and limit the maximum pressure differential thereon.
