Abstract: The technical field of the invention is that of making “in-stream” burners which are placed directly inside a duct carrying a flow of gas, with the burners serving to heat the gas and being placed as burner rails that are generally made up of individual blocks. Such burners comprising a pipe on an axis XX′ and suitable for extending transversely across the flow direction of the gas, the pipe being fed with a fuel gas and being pierced by at least two holes in alignment on a common generator line, the burner also having a flame stabilizer formed by two deflector-forming fins diverging on either side of the generator line. According to the invention, at least one of the holes is extended by a tube extending beyond the outer edges of the fins and pierced by at least one fuel gas ejection orifice at its distal end.

Abstract: The invention relates to the field of frequency measuring, in particular to extremely accurate difference frequency measuring as it is used in the area of measuring instruments, e.g. in scanning atomic force microscopes or other scanning probe microscopes, or in the area of thermogravimetry for determining extremely small masses in the ng-range. The invention relates in particular to the principle of such a hybrid frequency measuring device or frequency detector, i.e. a frequency measuring device or frequency detector comprising both digital and analog components or groups of components. The invention also relates to an advantageous use of such a frequency detector for evaluation of the frequency measurements of a scanning probe microscope. A frequency measuring arrangement can be at least partly integrated in a measuring head of a scanning probe microscope, thus enabling a robust, and at the same time sensitive, measuring arrangement.

The first channel communicates with the outlet of a source of the molten material. The sprue bar assembly further comprises an adjustable sprue bar section having a second channel through which molten material flows and a powered unit for holding the adjustable sprue bar section in contact with the fixed sprue bar section so that molten material can flow from the first channel to the second channel without leaking and for changing the length of the sprue bar assembly as needed to accommodate molds of different shutheights.

Abstract: A pen or pencil having a shaft which in its peripheral surface has at least one first and at least one second surface region. Irradiation of the first surface region with light of a first light quantity per unit of surface area results in an emission of visible light in the second surface region, wherein the light quantity emitted in the second surface region per unit of surface area for at least one first frequency is greater than the light quantity per unit of surface area of the first frequency, which is absorbed in the first surface region.

Abstract: The present invention is directed to a system and method for aircraft engine monitoring to permit management of individual aircraft in a fleet of aircraft. A processing system collects data on engine operational parameters and then uses this data to perform calculations to accurately determine time remaining until service and relative wear of specific engines in the fleet of aircraft. The time remaining until service and relative wear is displayed on a display screen which is configured to display this data for each engine separately. The displayed results can be used by an aircraft maintenance manager to accurately determine if the aircraft engines are being operated according to a maintenance plan, or to rotate the service of the aircraft to balance the wear on the aircraft engines in the fleet.

Abstract: A process for in situ upgrading of a heavy hydrocarbon includes the steps of (a) positioning a well in a reservoir containing a heavy hydrocarbon having an initial API gravity of less than or equal to about 8; (b) injecting a light solvent into the well at reservoir conditions so as to provide an upgraded hydrocarbon in the reservoir, the upgraded hydrocarbon having an improved API gravity greater than the initial API gravity; and (c) producing the upgraded hydrocarbon from the well.

Abstract: A centrifugal pump with a floating ring seal (34) provided in a sealing chamber (32) for pumped fluid and web-like flat pieces arranged in the sealing area (32) between the outer wall and the floating ring seal (34) extending in a longitudinal section approximately parallel to the pump shaft (14). At least one closable ventilation opening (47) is arranged in the head area of the sealing chamber (32), in addition to one blade-like flat piece (60, 60a) which is disposed on the peripheral wall (48) on both sides of the ventilation opening (47). From a cross-sectional point of view, both flat pieces (60, 60a) are inclined towards each other and define an antechamber with a slit (70) which is parallel to the pump shaft (14) at a distance from the peripheral wall. Preferably, the blade-like flat pieces (60, 60a) are fixed to the radial wall (55) and the free blade edge parallel thereto defines a radial slit with the other radial wall.

Abstract: A centrifugal separator for separating oil suspended in air and especially intended for use with aircraft engines includes a rotatable chamber filled with a relatively rigid porous material and is driven by a hollow shaft. An inlet for the mixture of air and oil is provided in one end wall of the chamber and separate outlets for oil and air are provided in the outer and inner cylindrical walls of the chamber respectively. Oil droplets are formed in the rigid porous material and ejected out through the oil outlet under centrifugal forces while air relatively free from oil exits the air outlet and enters into the inside of the hollow shaft under the pressure difference. A cut-away area is formed in the rigid porous material to facilitate ejection from the separator of the oil droplets formed in the porous material to clear the passages of the porous material and facilitate a continuous movement of the mixture of air and oil mist.
