Title: Rope traction elevator
Inventor: LATORRE MARCUZ CARLOS
IPC: B66B1/04
Filed: 1999-07-12
Granted: 2008-04-29
Abstract: This elevator drive for a rope traction elevator, which is intended for installation in an elevator hoistway, consists of a gear (2) with traction sheave (6), a motor (1) in an upright position on top of the gear (2), a brake (3, 4, 5) and suspension elements (18) which are slung over the traction sheave (6) and provide vertical motion for an elevator car with a counterweight. In view of the limited amount of space available in the elevator hoistway, the elevator drive should take up as little surface area as possible. To achieve this, the motor (1) and the gear (2) are inclined at an angle of (.beta.) to the vertical. With this slightly tilted arrangement no part of the motor (1) extends beyond the horizontal boundary of the gear (2). Furthermore, the brake (3, 4, 5) is a part of the gear (2) and non- detachably fastened to it, which makes it possible to mount the motor (1) on the gear (2), and to dismount it therefrom, without difficulty.

Granted: 2003-03-11
Abstract: A filterbank structure is provided which provides a flexible compromise between the conflicting goals of processing delay, filter sharpness, memory usage and band interaction. The filterbank has an adjustable number of bands  and a stacking which provides for a selectable shift of band frequencies to one of two discrete sets of center frequencies. The width of the bands and hence the number of the bands is selected depending upon acceptable delay, memory usage, and processing speed required. The flexibility in terms of stacking of the bands provides twice the number of potential band edge placements, which is advantageous for hearing loss fitting, especially at lo w frequencies. The same filter coefficients can be used for analysis and synthesis, to reduce memory usage.

Filed: 1999-11-12
Granted: 2007-05-08
Abstract: An improved double wall tank has two or more threaded fittings, with a steel outer tank and a thermoplastic inner tank. The inner tank is formed within the outer tank by rotational molding. The inner tank is bonded to the outer tank in an area of the fittings, but is otherwise separate and apart from the outer tank. Before carrying out the rotational molding process, bonding material is applied to the outer tank in the area of the fittings. The thermoplastic material is in powder form and includes mold release material. The thermoplastic material is inserted into the outer tank before rotational molding. The degree of shrinkage of the inner tank can be controlled by air pressure including an area between the fittings.

Title: Expression of endogenous genes by non-homologous recombination of a vector construct with cellular dna
Inventor: HARRINGTON JOHN J
IPC: C12N15/11
Filed: 1998-09-25
Granted: 2014-11-18
Abstract: The present invention relates generally to activating gene expression or causing over-expression of a gene by recombination methods in situ. The invention also relates generally to methods for expressing an endogenous gene in a cell at levels higher than those normally found in the cell. In one embodiment of the invention, expression of an endogenous gene is activated or increased following integration into the cell, by non-homologous or illegitimate recombination, of a regulatory sequence that activates expression of the gene. In another embodiment, the expression of the endogenous gene may be further increased by co-integration of one or more amplifiable markers, and selecting for increased copies of the one or more amplifiable markers located on the integrated vector. The invention also provides methods for the identification and expression of genes undiscoverable by current methods since no target sequence is necessary for integration. The invention also provides methods for isolation of nucleic acid molecules (particularly cDNA molecules) encoding transmembrane proteins, and for isolation of cells expressing such transmembrane proteins which may be heterologous transmembrane proteins. The invention also relates to isolated genes, gene products, nucleic acid molecules, and compositions comprising such genes, gene products and nucleic acid molecules, that may be used in a variety of therapeutic and diagnostic applications. Thus, by the present invention, endogenous genes, including those associated with human disease and development, may be activated and isolated without prior knowledge of the sequence, structure, function, or expression profile of the genes.

Abstract: L'invention concerne un procédé et un dispositif permettant de préparer et de former, par chauffage au moyen d'un dispositif de chauffage (12), une soudure plastique entre une pièce (13) et un second composant devant être fixé à ladite pièce (13). Si une force est appliquée, l'élément de chauffage (12) a tendance à déformer la surface de contact surtout dans le cas de pièces creuses à paroi mince, telles que les récipients plastiques. Jusqu'à présent, les procédés présentés consistaient à mesurer, au moyen d'un capteur, le degré de déformation puis à réajuster la position du dispositif de chauffage (12) en fonction de la déformation déterminée. Dans la présente invention, aucune mesure de la déformation n'est nécessaire. Au lieu de cela, on utilise un élément élastique qui réajuste automatiquement la position du dispositif de chauffage en cas de déformation de la pièce (13), de manière à effectuer un pré-chargement entre le dispositif de chauffage (12) placé au niveau de la surface de contact de la pièce (13) et ladite pièce (13).

Abstract: The present invention relates to overflow protection of a buffer of a first- in- first-out type, able to store a first number x of messages from the digital module. The method is characterised by creating and sending pace messages to the buffer from the digital module, addressed to the first module itself, and keep track of the pace in which they are sen t and received. The criterion for sending pace messages is based on the number of sent messages. The sending of messages is halted if a criterion, based on the number of sent pace messages and the number of received pace messages, determines that there exists a risk for overloading the buffer. The device comprises means for creating a pace message, a pace sender for sending the pace message, a receiver for receiving the pace message, and means for halting the process of sending messages.
