Patent EP-0310632-A4 (EP)
Inventor: GOLDSMITH ROBERT L
IPC: H04W84/02
Filed: 1987-12-11
Abstract: Dispositif de filtration (10) à écoulement tangentiel comprenant une structure de matériau poreux définissant une pluralité de passages (12) qui s'étendent dans le sens longitudinal depuis l'extrémité d'alimentation (40) de la structure jusqu'à une extrémité de rétention, ainsi qu'un certain nombre de conduites de filtrat (14) disposées à l'intérieur de la structure pour véhiculer le filtrat au sein de la structure vers un collecteur annulaire (36). Les conduites de filtrat (14) matérialisent des trajets de moindre résistance à l'écoulement par rapport aux trajets qui traversent le matériau poreux, et la structure est construite de telle façon que les conduites de filtrat (14) soient réparties parmi les passages (12) pour offrir au filtrat des trajets d'écoulement à basse pression depuis les passages (12) au travers du matériau poreux vers les conduits (14) voisins. Le dispositif de filtation à écoulement tangentiel peut également être utilisé comme support de membrane dans un dispositif à écoulement tangentiel de microfiltration, d'ultrafiltration, d'osmose inverse, de séparation gazeuse ou de perévaporation.

Title: Neutron range spectrometer
IPC: G01T1/36
Filed: 1989-03-09
Abstract: The invention is a neutron range spectrometer (10) and method for determining the neutron energy spectrum of a neutron source (12). Neutrons from the source (16) are collimated and detected by a position sensitive neutron counter (20, 28). The counter (20, 28) determines the position along the axis (26) where the neutrons (16) are absorbed by the absorbing material (24) in the counter (20). From the interaction positions, a computer (32) analyzes the data and determines the energy spectrum of the incident beam (16). The counter (20) is preferably shielded by a neutron-absorbing material (34) such as helium-3. The computer (32) solves a series of equations to determine the number of neutron interactions at a particular location along the axis (26). These equations are used to determine the energy spectrum of the neutron beam (16).

Title: A battery saving apparatus and method providing optimum synchronization codeword detection
IPC: H04W52/02
Filed: 1990-01-16
Abstract: A battery saving apparaus (100) for supplying power to a selective call communication receiver for enabling the detection of a synchronization codeword in data received in a predetermined signaling format comprises circuits (132, 140, 142) for supplying power to the receiver, and a circuit (112) for detecting valid data received during a first portion of the first predetermined time interval. Power is maintained to the receiver for the remainder of the first predetermined time interval when valid data is detected in the first portion. A synchronization codeword detector (116) is included for detecting a synchronization codeword. When valid data is subsequently detected following a second portion of the first predetermined time interval and the synchronization codeword is not detected in the first predetermined time interval, power is maintained to the receiver for a second predetermined time interval to further enable detection of the synchronization codeword.

Title: Real-time dynamic holographic image storage device
IPC: G03H1/02
Filed: 1990-03-02
Abstract: A real-time dynamic holographic image storage device uses four-wave mixing in a pair of photo-refractive crystals (10, 14). An oscillation is produced between the crystals (10, 14) which can be maintained indefinitely after the initial object beam is discontinued. The object beam produces an interference pattern in a first crystal (10) to produce a phase-conjugate object beam which is directed towards the second crystal (14). In the second crystal (14), another interference pattern is created which produces a reconstructed object beam. The reconstructed object beam is directed back towards the first crystal (10). The interference patterns are produced by the interaction of the object and phase-conjugate object beams with a read and write beam in each of the crystals (10, 14). By manipulation of the ratio of the read and the write beam intensities in at least one of the crystals (10, 14), the phase conjugate or reconstructed object beam output therefrom can be amplified to maintain stable oscillation between the two crystals.

Abstract: L'invention se rapporte à un concasseur servant à concasser une colonne ou une poutre d'une structure en béton en maintenant la colonne ou la poutre au moyen de lames de concassage agissant par compression, disposées à l'extrémité avant d'un bras et servant à ouvrir et à fermer ce bras. Un cylindre hydraulique (1) pour l'ouverture et la fermeture du bras comprend un second cylindre dans lequel les fonds de deux cylindres (3' et 3') sont reliés entre eux, ainsi qu'un premier cylindre dans lequel les fonds de cylindres ajustés dans les cylindres respectifs (3' et 3') servent de pistons (9). Lorsqu'un fluide hydraulique est introduit par un cinquième orifice à huile (18), prévu sur le fond du second cylindre, le premier cylindre (2) est amené à se déplacer vers l'avant, et, lorsque le premier cylindre (2) atteint la fin de sa course, le piston du premier cylindre est amené à se déplacer vers l'avant, ce déplacement vers l'avant du piston entraînant la fermeture du bras, ce qui permet de concasser par compression la structure en béton. Lorsque le fluide hydraulique est introduit par un quatrième orifice à huile (16), le fluide hydraulique ainsi introduit amène un piston (5) à se déplacer vers l'arrière à travers un deuxième orifice à huile (10) et un passage à huile (11), et, lorsque le piston (5) atteint la fin de sa course, la pression du fluide hydraulique agit sur le fond du premier cylindre à travers un interstice (entre 24 et 25) ayant une résistance au fluide sélectionnée, afin d'établir une communication entre le deuxième orifice à huile (10) et la chambre de fluide (14) côté tige de piston du deuxième cylindre, pour amener le premier cylindre (2) à se déplacer vers l'arrière, ce déplacement vers l'arrière servant à ouvrir le bras. L'amenée du fluide hydraulique dans le cylindre hydraulique (1) s'effectue uniquement via le quatrième orifice à huile (16) et le cinquième orifice à huile (18), permettant ainsi une commande aisée.

Title: Heat exchanger for a water heater.
Inventor: AFSHAR MOHAMMAD REZA
IPC: F24H1/40
Filed: 1992-09-10
Abstract: A swimming pool or spa heater unit having a heat exchanger manifold designed to permit the use of direct plastic piping connections to the manifold header. The manifold is principally characterized by a header end having an inlet port and outlet port located on a level below the manifold inlets and outlets communicating with the heat exchanger. The inverted arrangement of the header ports relative to the manifold inlets and outlets to the heat exchanger permits unreturned water in the unit heated by residual heat from the heater to form a temperature gradient therebetween which prevents the temperature of the water at the header connection from reaching a level incompatible with the use of direct plastic piping connections. The manifold is also integrally provided with weirs which serve to provide dry-fire protection for the heater.

Title: Method for preparing foamed gypsum product
Inventor: SUCECH STEVEN W
IPC: C04B24/16
Filed: 1996-12-18
Abstract: The invention provides an improved method for preparing foamed gypsum products. The invention can utilize a single mixing chamber and significantly improve the efficiency of foaming agent usage. In the method of the invention the point of insertion of aqueous foam into calcined gypsum slurry is positioned such that the foam is agitated less than the calcined gypsum to thereby minimize destruction of the foam while still uniformly dispersing the foam in the calcined gypsum slurry. This is accomplished, for example, by locating an inlet for foam closer to the discharge outlet of a slurry mixing chamber than the location of the inlet for calcined gypsum or by locating the foam inlet in a discharge conduit connected to the discharge outlet of the slurry mixing chamber.
