Abstract: Un rouleau (10) utilisé comme rouleau de support, rouleau d'appui ou rouleau entraîné dans des dispositifs d'enroulement, est composé d'un élément de rouleau externe cylindrique (24) sur lequel on applique une couche intermédiaire souple et élastique (26) d'un matériau élastomère. Sur la couche intermédiaire (26) est appliqué un revêtement de rouleau externe (33) en acier à ressorts à paroi mince, qui peut être déformé, par la pression de contact du rouleau, sur un plan perpendiculaire par rapport à l'axe, et qui peut être pressé contre le périmètre externe du rouleau (2). Une large zone de contact est ainsi créée, permettant d'obtenir une pression de serrage spécifique plus faible et une raideur d'enroulement amoindrie. Des canaux (27, 28) produits dans la couche intermédiaire (26) servent à augmenter la flexibilité et le refroidissement.

Abstract: An escalator is formed of a plurality of steps traveling in a continuous conveyor between a pair of spaced apart skirt plates. Each step has lateral safety boundaries attached to the side edges thereof. Spring inserts are positioned between the outermost ribs of the tread plate and the riser of the step to maintain the safety boundaries in contact at all times with the skirt plates. Thus, differences in the distance between the skirt plates and deviations of the travel path of the steps are equalized and the air gaps between the skirt plates and the side edges of the steps are closed at all times. The material from which the safety boundaries are made is selected to provide the lowest possible friction losses and to prevent scraping noises during operation.  However, the safety boundaries will wear down before the skirt plates and worn out safety boundaries can be replaced without having to dismantle the corresponding step from the step conveyor.

Abstract: Dans les conduits souterrains miniers, la qualité de l'air est un élément primordial à la santé des travailleurs. Ainsi, il est important que le nombre de machines y circulant soit réduit au minimum, la productivité des travailleurs étant augmentée d'autant. Les niveleuses actuellement utilisées n'ont pas accès à certaines parties de ces conduits, telles que les chantiers. De plus leur coût d'acquisition et d'entretien est dispendieux. D'autre part, les appareils amovibles actuellement utilisés et fixés en-dessous de la machinerie, consistant en une lame verticale, sont trop volumineux par rapport à l'espace disponible entre les roues avant et arrières des machines minières, cet espace étant déjà utilisé à d'autres fins. De plus, la surface du sol desdits conduits étant trop cahoteuse, une lame y serait inutile puisque sa hauteur devrait sans cesse être ajustée. Ainsi la présente invention consistant en un appareil amovible fixé en-dessous des machines minières existantes anéantie le nombre de niveleuse dans lesdits conduits, augmentant la qualité de l'air et la productivité des travailleurs. Cet appareil fixé sous la machinerie minière facilite le nivelage des endroits inaccessibles aux niveleuses actuelles, cette machinerie étant déjà conçue pour s'y rendre. Par son profil bas, l'invention cadre parfaitement à l'espace disponible en-dessous desdites machines. De plus, par la position de ses ancrages, l'invention s'ajuste automatiquement aux conditions du sol. Enfin, l'appareil exige aucun entretien mécanique et coûte moins cher que les niveleuses usuelles.

Abstract: The present invention provides novel devices including magnetic components and novel methods for making them. In a first aspect, the invention provides a device comprising a metallized magnetic substrate (e.g., 5) having anaperture (e.g., 50). At least one metallized path (e.g., 20) passes through the aperture and around a portion of the substrate to define a magnetic component which has aflux path in the plane of the substrate and substantially confined within the substrate. The winding can pass around a substrate edge or through a second aperture. Advantageously, other circuit elements such as metallized interconnects (e.g., 55) and electronic components (e.g., 401) are disposed on the substrate to form a device. In a further aspect, the invention provides methods for metallizing magnetic substrate to form devices including magnetic components. In one embodiment, a green ceramic body (e.g., 5) comprising at least one ceramic layer is provided in an unfired state. At least one aperture (e.g., 50) having at least one conductively coated side wall pathway (e.g., 56) is formed within each ceramic layer. Top and bottom surface portions of the ceramic body are metallized such that the metallized surface portions (e.g., 20) form a continuous conductive region with the side wall conductive pathway to create a conductive winding about the ceramic body. The ceramic body with the conductive winding formed thereon is fired to yield a substrate including a magnetic component. Preferably after sintering, additional metal is plated on the conductive regions to enhance current-carryingcapacity.

Abstract: Disclosed herein is a drain valve for a bathtub or other gravity drained container. When energized with an electrical pulse, a solenoid mounted directly below the drain elbow drives the poppet upward, which unseals the outlet drain. A permanent magnet latches the solenoid armature in place in the up position. The valve is closed by energizing the solenoid with a pulse of opposite polarity which pulls the armature downward and out of the influence of the permanent magnet. A piston a sleeve overnested by a movable shroud provides leakage protection and allows manual opening and closing.

Abstract: A method for making submicrometer metallic carbides and submicrometer solid solution metallic carbides from a source of at least one metallic oxide and carbon involves the rapid heating of a reactive particulate mixture of the source(s) and carbon in order to a chieve a resulting particulate size of less than 1 micrometer. The rapid heating may produce either a finished product or a precursor. If a precursor is produced, it may be admixed with additional carbon and subjected to a second rapid heating step to prepare a finished p roduct. Submicrometer sized metallic carbides and solid solution metallic carbides were suitable for use in commercial ceramic applications. The smaller sized particles produce a product having superior toughness and hardness.

Abstract: Non-invasive therapeutic treatment and/or quan-titative evaluation of musculoskeletal tissue are per-formed in vivo by subjecting musculoskeltal tissue (11) to an ultrasonic acoustic signal pulse extraction, involving a composite sine wave signal consisting of plural discrete frequencies that are spaced in the ul-trasonic region to approximately 2 MHZ, and repeated substantially  in the range of 1 Hz to 1000 Hz. In a quantitative evaluation the signal is supplied to one of two transducers (12, 13) on opposite sides of the tissue, and the signal received by the other transducer is processed (14): (a) to obtain an averaged per-pulse signal and (b) to produce a Fourier transform of the averaged per-pulse tissue transmittal signal. In a sep-arate operation, the same transducers are subjected to the same excitation, reception and processing, using a medium of known acoustic properties and path length to produce a reference Fourier transform. In a ther-apeutic treatment, the transducer (12) excited by the composite sine wave signal is applied for a time pe-riod and magnitude.

Title: Combination direct and indirect closed circuit evaporative heat exchanger with blow-through fan
Inventor: KORENIC BRANISLAV
IPC: F28C1/14
Filed: 1996-04-19
Granted: 2000-08-08
Abstract: A heat exchange apparatus which can be used as an evaporative condenser, fluid cooler or wet-air cooler, is provided with a direct evaporative heat exchange section overlying an indirect evaporative heat exchange section. An air entry zone common to both heat exchange sections receives an air stream blown into this zone by at least one fan, thereby pressurizing the plenum such that the air stream is forced to split and enter each section while inside the apparatus. This eliminates the need for separate air entries, thus condensing the size and cost of the apparatus, while increasing heat exchange capacity. A countercurrent air flow pattern through the direct section provides a uniformly cooled evaporative liquid for use in the indirect section. The evaporative liquid flow is parallel to the air stream provided in the indirect section. A process fluid inside the circuits of the indirect section can accept or reject heat from the evaporative liquid received from the direct section, with a part of the heat being is transferred into the indirect section air stream in sensible and latent form, thus increasing or decreasing the enthalpy of the air stream. The remaining heat can be either stored or released from the evaporative liquid to increase or decrease its temperature. The evaporative liquid is collected in a sump and then pumped upwardly for re-distribution across the direct evaporative heat exchange section.
