Title: Device and procedure for the automatic diagnosis of a technical system with efficient storage and evaluation of data about measures
Inventor: IWANOWSKI SEBASTIAN
IPC: G06F17/50
Filed: 1997-04-18
Granted: 2005-11-01
Abstract: The invention relates to an advantageous embodiment of the process of the knowledge-based model-based diagnosis. The object is to obtain costs from modular components to achieve efficient knowledge acquisition of the costs. It should be possible to use said process for all problems posed which can be solved by model-based diagnosis software, in particular to generate decision trees from model-based knowledge. In the event of the diagnosis software containing a reason maintenance system (RSM), an interface and control system between the RMS and an inference machine should be provided which enables calculations for different moments to be carried out efficiently. The object, to obtain costs from modular components, is attained by using local measures. An efficient and flexible interface and control system between the RMS and the inference machine is achieved by a RMS controlled by two external foci. Decision trees are produced by a process which uses a systematic test proposal which takes into consideration costs and the associated situation.

Title: Pool cover
Inventor: ELLISON EDWARD J
IPC: F24S90/00
Filed: 1999-03-02
Granted: 2000-07-25
Abstract: The pool cover is made of multi-layer light weight construction having a translucent top layer to permit sunlight to pass through an opaque bottom layer for absorbing sunlight passing through the transparent layer. In addition, a plurality of pockets are formed in the opaque layer having air encapsulated therein. When in use, the opaque layer becomes heated by sunlight thereby transferring heat by contact to the body of the water in the pool while also blocking light from the body of water to inhibit algae growth. The heated trapped air also serves to conduct heat to the body of water while also acting as a thermal insulation barrier during non-daylight hours. The pool cover may also be turned upside down in use. In other embodiment, all layers may be opaque.

Granted: 2006-09-05
Abstract: A process for producing liquid and/or gaseous products from gaseous reactants comprises feeding (14) them, at a low level, into a slurry bed (40) of particles suspended in a liquid, to react as they rise therethrough to form the products, the reactants and any gaseous product assisting in maintaining the suspension. The liquid product forms, together with the suspension liquid, the liquid phase of the bed. Any gaseous product and unreacted reactants rise from the bed into a head space (44). Slurry passes downwardly in the bed through downcomers (22, 32) located respectively in first and second downcomer regions {20, 30) of the bed, thereby redistributing solid particles within the bed. The second downcomer region is spaced vertically with respect to the first downcomer region. Any gaseous product and unreacted reactants are withdrawn (16) from the head space (44) and liquid phase is withdrawn (18) from the bed. Preferably a Fischer-Tropsch synthesis takes place with the gaseous reactants being in the form of a synthesis gas stream comprising mainly carbon monoxide and hydrogen.

Abstract: A method of assembling a heat exchanger unit (12) that involves an expansion technique for securing a heat exchanger tube (18) to a number of fins (24) without physical intrusion into the tube passage. The method includes forming the tube (18) to have substantially parallel tube portions (26). Pairs of tubes portions (26) may be connected by a bend or an elbow (28) to yield a serpentine tube configuration. Each of the fins (24) is formed to include one or more apertures that are sized to receive the tube portions (26). The fins (24) are then arranged to form a fin pack (22), so that their apertures are aligned to form an aggregate passage through the fin pack (22). The tube portions (26) are then inserted into the aggregate passage, such that the elbow (28) (if present) and/or the ends of the tube (18) remain outside the fin pack (22). Finally, the tube portions (26) are expanded to contact and become mechanically secured to the fins (24) through the application of a compressive force in a longitudinal direction to the tube portions (26).

Abstract: It is described a discrimination procedure of a wanted signal from a plurality of cochannel interferents received by array antennas of GSM or DCS base transceiver stations. The procedure includes a phase for the estimate of the number and arrival directions of the interferents, and of the wanted signal, followed by a spatial filtering phase in which the signals transduced by the sensors of the array are linearly combined among them through multiplication coefficients, or weights, organized in a vector w satisfying the two following conditions: A) Spatial filtering constrains the gain of the array in the ratio between wanted signal and noise, compared to the traditional use of a single sensor, so that the gain is not less than a properly selected threshold; B) it minimizes the ratio between the sum of interferents' powers and wanted signal power.
