The invention describes a heating system (100) and a corresponding method of heating a heating surface (180) of an object (150, 950) to a processing temperature of at least 100° C., wherein the heating system (100) comprises semiconductor light sources (115), and wherein the heating system (100) is adapted to heat an area element of the heating surface (180) with at least 50 semiconductor light sources (115) at the same time. The heating system (100) may be part of a reactor for processing semiconductor structures. The light emitted by means of the semiconductor light sources (115) overlaps at the heating surface (180). Differences of the characteristic of one single semiconductor light source (115) may be blurred at the heating surface (180) such that a homogeneous temperature distribution across a processing surface of a, for example, wafer may be enabled.

A method and system for separating human waste solids from liquid for a shipboard toilet system that allows for the separation of solid waste, compaction of the solid waste and storage of solid waste. Wastes are deposited into a shipboard toilet system that uses vacuum toilets to flush waste into a large, inclined solid waste separation tank. A vacuum pump is attached to the separation tank to maintain negative pressure within the tank and system and to move the separated liquid stream. The separation tank has a separating screen disposed across its entire width to retain solid wastes while allowing liquid to flow through. After separation from liquids, solid waste material is compacted and dewatered with a helical screw through an inclined tube, and packaged for later removal as landfill or burned in the ship incinerator.

A vacuum assist system and process for handling cutting fluid and chips collected from a series of machine tools includes a closed header pipe extending below a series of sumps associated with the machine tools, the sumps draining into the header pipe. The header pipe has a down leg extending vertically down to a filter tank which is opened periodically to drain the header pipe, developing a vacuum which assists the flow of liquid down the header pipe so as to insure a sufficient flow velocity in the header pipe to carry the collected chips out of the header pipe and into the filter tank with the cutting fluid.

Methods and systems are provided for controlling a fuel system in a hybrid vehicle. Before canister purging is stopped by closing a purge valve, a canister vent valve is closed to hold fuel tank vacuum. Then, during a subsequent canister purge, the purge valve is opened before opening the vent valve, allowing canister purge to initiate under fuel tank vacuum conditions.

An apparatus and process for removing moisture from sludge. The apparatus comprises a housing having an inlet and outlet for respective receipt and discharge of the sludge. A conveyor is located in the housing and is configured to transport the sludge from the inlet to the outlet. The apparatus further comprises a heater to heat the sludge to remove moisture therefrom whilst the sludge is being transported by the conveyor. The apparatus also comprises a vacuum pump arranged to extract air from the apparatus and, at the same time, to cause moisture removed from the sludge to flow therefrom together with the extracted air.

A sealed thermal interface component minimizes or eliminates the exudation of fluids, such as silicone oils, while preserving the excellent thermal conductivity of silicon-based thermal pad materials and enhancing the conformability of the component. In an example embodiment, one or more thermal pads are formed of conformable thermal management material that may exude fluid under elevated temperatures or over time. Film encapsulates the thermal pad or pads, forming a sealed and partially evacuated thermal interface component. In one embodiment of the invention, the thermal pad or pads are formed of an elastomeric silicon-based thermally conductive material and the film is made of polyurethane.

A device for removing a mass lodged in a choking victim's throat comprises a manifold, piston, spool, and latch. The manifold has first, second, and third conduits in selective fluid communication with each other, with the second conduit terminating in an orifice in a mouthpiece. The spool, having a transverse orifice, may be disposed in the third conduit, slidable between a first position where the orifice permits fluid communication between the first and second conduits, and a second position where the spool blocks fluid communication. The piston is slidably disposed within the first conduit, and with the spool is in the second position, the latch is usable to secure the piston relative to the manifold at one or more discrete positions to create a measured amount of vacuum pressure in the first conduit. The vacuum pressure is transmitted to the mouthpiece by movement of the spool to said first position.

A sealed thermal interface component minimizes or eliminates the exudation of fluids, such as silicone oils, while preserving the excellent thermal conductivity of silicon-based thermal pad materials and enhancing the conformability of the component.

The present invention provides a plasma display panel without any injection tip and a method of manufacturing the same. The plasma display panel without any injection tip has a structure capable of directly injecting gas for electric discharge into the plasma display panel through an injection hole of a lower glass substrate using a vacuum apparatus while manufacturing the plasma display panel, thus sealing the plasma display panel in the vacuum. Therefore, the plasma display panel without any injection tip reduces a thickness thereof, thus reducing a space required to install the plasma display panel. Furthermore, the plasma display panel without any injection tip avoids damages, caused by an injection tip of conventional plasma display panels, during a process of transporting or installing the plasma display panel.
