Title: Dispositif laser
Inventor: DUNN MALCOLM HARRY
IPC: G02F1/39
Filed: 1997-06-26
Granted: 2005-03-15
Abstract: L'invention concerne un dispositif laser comprenant un générateur paramétrique optique (GPO) non colinéaire et une source d'onde de pompage (4). Le GPO contient un cristal non linéaire (1) monté à demeure à l'intérieur du générateur, dans lequel, par rapport à un axe optique (2) du cristal non linéaire (1), l'orientation de l'onde de pompage (3) et l'orientation de chaque onde générée (5) sont sensiblement celles qui permettent la production d'un point d'inflexion entre, d'une part, l'intérieur d'une courbe d'accord d'une longueur d'onde et, d'autre part, l'orientation d'une onde de pompage d'une des ondes générées, le but étant d'obtenir une sortie spectrale à large bande. Ce dispositif connaît de nombreuses applications. Il peut servir notamment d'amplificateur pour onde initiale d'entrée dans lequel le cristal ne doit pas subir de rotation pour s'accorder à la longueur de l'onde initiale, ou comme élément d'une source à bande étroite à accord continu. Il s'applique également à l'analyse spectrale ainsi qu'à la tomographie cohérente.

Title: Self-supporting liner for internal lining of vehicle roofs
Inventor: SOTO LOSADA PABLO
IPC: B32B27/36
Filed: 1997-09-17
Granted: 2008-01-29
Abstract: The liner is comprised of a "support" structure and a decorative or external coating layer. The "support" structure is comprised of three superimposed layers based on polyester fibers and wherein the intermediary layer (1) is considerably much thicker than the external layers (2), the decorative layer (3) has a coating made of polyester or any other appropriate material in order to provide for the recycling of the assembly. The bonding of the various layers together is achieved by preheating the layers (1 and 2) and by the corresponding moulding of the "support" formed by said layers including the external or decorative layer (3); no additional adhesive is required to maintain all three layers together.

Abstract: A process for activating double metal cyanide catalysts is disclosed. A poly ol starter or starter/catalyst mixture is heated under vacuum under conditions effective to achieve improved stripping compared wit h that which can be achieved through conventional vacuum stripping. Coupling vacuum stripping with inert gas sparging or stripping in the presence of an organic solvent gives a starter/catalyst mixture that activates rapidly in an epoxide polymerization process. Rapid activation makes process start-ups reliable and reduces cycle time. The process gives polyols with lower viscosity, lower polydispersity, and lower unsaturation for better polyurethanes.

Filed: 1998-10-28
Granted: 2009-07-21
Abstract: An interactive system for debugging programs in which a persistent data base system responds to update queries containing debugging information from a debugging information source and to read queries on the debugging information from an interactive interface. The interactive interface produces the read queries in response to inputs from users and formats the results of the read queries as required by the user. One source of inputs is a standard Web browser for which the interactive interface functions as a Web server. The system also includes a command channel by which the source of debugging information receives commands from the interactive interface. In one embodiment, the command channel is implemented in the data base. In a disclosed implementation, the source of debugging information provides memory debugging information. Also disclosed are techniques for using an automatic memory management system to reduce memory fragmentation and heap footprint size.

Title: Coil stop for rail road coil car
Inventor: AL-KAABI MOHAMMED
IPC: B61D17/10
Filed: 2000-12-15
Granted: 2011-02-15
Abstract: A coil car has a pair of deep side sills and a trough structure mounted to, and suspended between, the deep side sills for carrying coils. The side sills extend between the rail car trucks and act as a pair of deep side beams for carrying vertical loads. The deep side sills are arranged to extend above and below the center sill of the coil car to give vertical stiffness to the coil car. The top chord members of the side sills are outwardly splayed relative to the bottom chord members of the side sills. Cross-bearers extend outwardly and away from the center sill to attach to the side sills. The trough structure has three parallel, longitudinally extending troughs - a central trough lying between two laterally outboard outer troughs. Each trough is shaped to cradle steel coils, or other similar loads, between its inwardly and downwardly sloping shoulder plates. The shoulder plates are lined with cushioning to buffer coils during loading or travel. The outboard troughs are mounted above longitudinally extending stringers and are carried at a greater height relative to top of rail than the central trough. The car has coil stops to discourage longitudinal shifting of loaded coils. The coil stops have rollers to facilitate repositioning during loading, and a mid-span step and hand grabs to facilitate climbing over the coil stop by personnel walking along the trough structure.

Abstract: A method that is usable with an NMR measurement apparatus includes averaging first spin echo trains acquired from different regions of a sample to form a second spin echo train. The first spin echo trains are used to produce a first estimate of a property of the sample, and the first estimate has a first resolution and a first accuracy. The second spin echo train is used to produce a second estimate of the property, and the second estimate has a second resolution that is lower than the first resolution and a second accuracy that is higher than the first accuracy. The first and second estimates are combined to produce a third estimate of the property. The third estimate has a third resolution near the first resolution of the first estimate and a third accuracy near the second accuracy of the second estimate.

Title: Method of regulating a high temperature gaseous phase process and use of said method
Inventor: SCHNEWEIS STEFAN
IPC: G05D27/02
Filed: 2000-02-09
Granted: 2004-07-06
Abstract: The invention relates to a method of regulating a high temperature gaseous phase process such as CVD or CVI on the basis of a measuring curve obtained by infrared spectroscopy. Said measuring curve indicates at least one spectral range that is characteristic of the regulation of the process and that differs from the background of the measuring curve. The aim of the invention is to allow a regulation of high temperature gaseous phase processes optimally and quickly even if the temperatures change during the process. To this end, a straight line is calculated directly from the measuring curve on the basis of the initial and the end values of the characteristic spectral range. The process is then regulated by integration of the spectral range above the straight line or by determination of the maximum height of the spectral range above the straight line or by referring to another characteristic value of the spectral range with respect to the straight line.
