Title: Eolienne integree a jeu de pales de rotor multiples
Inventor: SHIN CHAN
IPC: F03D11/02
Filed: 1995-06-23
Granted: 2002-08-20
Abstract: Eolienne comportant un jeu de turbines à rotor captant la force du vent à la manière d'une hélice, ce jeu étant composé d'une turbine à pale de rotor auxiliaire en amont située à l'extrémité antérieure de l'ensemble roue conique-roue planétaire, et d'une turbine à pale de rotor principale en aval. Ces pales de rotor tournent dans des sens contraires, et un élément de prolongement permet à la turbine principale d'être mue par un vent de vitesse normale en évitant les effets aérodynamiques de turbulence de sillage créés par le mouvement de la pale de rotor auxiliaire. Cette éolienne intégrée à pales de rotor multiples et à ultra-grande échelle possède quatre jeux de turbines à pale de rotor captant la force du vent composées d'une seule turbine à rotor auxiliaire en aval, et de trois unités de turbine à rotor en amont réparties de manière homogène autour d'un moyeu de rotor pivotal central, sur des éléments de prolongement dont la longueur est égale au rayon de la pale de turbine auxiliaire. Ces éoliennes sont pourvues d'un système de calage des pales par microprocesseur, ce qui assure un rendement d'exploitation élevé et le blocage en cas de tempête.

Title: Method of venting smoke from highrise residential buildings
Inventor: IVISON JOHN T
IPC: F24F7/06
Filed: 1996-12-31
Granted: 2001-01-30
Abstract: In highrise residential buildings, venting to remove smoke from corridors is required in case of fire. In prior art systems, separate supply and exhaust shafts are provided and connected to each floor's corridor through  motor-controlled damper.  A disadvantage of the prior art system is that it thus requires two motorised dampers per floor and an expensive control system and wiring. The invention provides a method of venting smoke from a multi-floor building by providing a single supply and exhaust venting shaft communicating with each floor, with an air supply and exhaust grille opening into each corridor and communicating with the venting  shaft; providing a supply source of pressurized air, and an exhaust source of reduced pressure each communicating with the venting shaft, and damper means for selectively closing or opening the communication of the supply source of pressurized air and exhaust source of reduced pressure to the venting shaft. Under normal conditions where pressure is desired in the corridors, the supply source is operating and the communication of the supply source is open to the venting shaft and the exhaust source communication to the venting shaft is closed.  In case of a fire where venting of smoke or air is desired in at least one of the corridors is desired,  the exhaust source is activated and communication of the exhaust source to the venting shaft is opened and supply source communication to the venting shaft is closed.

Abstract: A method for rendering large-area time-based shadows. A first step is to pre-process a database of three dimensional constructs that define all primitives and attributes of the primitives in a three dimensional simulated environment. The pre-processing step determines the time relevant behavior of the shadows by calculating an angle at which the primitive is illuminated, and an angle at which illumination ceases. The second step is to process the database at run-time using the pre-processed database of three dimensional constructs and pre- calculated illumination and no-illumination angles.

Abstract: Narrowband subscriber terminals (40, 52, 58) of different narrowband networks are interconnected via a broadband network (48) that supports dissimilar signalling protocols to those maintained on the respective narrowband networks (40, 52, 58). A call server in a first narrowband network (40), in response to a call (100) from a first subscriber terminal (12) to a second subscriber terminal (68) in a second but different narrowband network (52), selects a phantom trunk (202) between the two networks. The phantom trunk has a unique circuit identity, which circuit identity is used in a first instance to relay to the second network an address of the second subscriber terminal (68). Then, in a second instance, the unique circuit identity is used to relay to the second network an address of the first subscriber terminal (68). By recognising that two connection requests have been received at opposite ends of the same phantom trunk, a processor in the second network is able to determine that a direct connection between the first and second subscriber terminals is required through the broadband network (48).

Abstract: A system for controlling the response of a ground fault circuit interrupter in the presence of random leakage currents due to the presence of a conductive media such as water or ice. The signal from a magnetic core differential transformer is applied to two filters in parallel. The first filter passes the fundamental frequency of the source and the second filter passes a broad band of frequencies starting at twice the fundamental frequency. The output of the filters are applied to a microprocessor which manipulates the filter outputs and compares certain of the filter outputs to a stored pattern of expected current leakage. The microprocessor operates a relay to disconnect the load from the source when a fault condition exists.
