Title: Traitement prealable d'hydrocarbures destine a empecher le deversement accidentel de petrole
Inventor: RICHMOND THEREZIA L
IPC: B09B1/00
Filed: 1995-07-11
Abstract: L'invention porte sur un procédé permettant de solidifier de manière réversible des hydrocarbures destinés à être transportés ou stockés pour empêcher leur déversement accidentel. Le procédé consiste à mélanger les hydrocarbures à une cire de pétrole, telle que de la paraffine, à la suite de quoi le refroidissement du mélange provoque sa solidification en une masse flottante homogène. La quantité minimale de cire de pétrole requise pour la solidification des hydrocarbures va dépendre du type de pétrole brut, du type de cire utilisée et de la température à laquelle la masse solidifiée va être maintenue pendant son transport en mer. Lorsque le transport du brut se fait par pétrolier, on peut effectuer le traitement préalable du brut à la cire dans les compartiments de stockage puis transporter le mélange sous sa forme solide. Le mélange solidifié en une masse homogène empêche efficacement le déversement accidentel du brut en cas de rupture de la coque et ne peut être déplacé par les courants marins. Le mélange solidifié flottant empêche le bateau de couler lorsqu'une brèche s'est ouverte dans la coque du bateau. Les résidus de raffinage, tels que les polychlorobiphényles contaminés, peuvent être solidifiés avec des quantités beaucoup plus importantes de cire pour assurer l'encapsulation complète du brut. Dans le cas du transport du pétrole brut, on peut extraire la cire à partir du brut en chauffant le mélange pour le liquéfier, les constituants étant ensuite séparés par distillation fractionnée.

Abstract: A structure of arranging an vehicle occupant protecting apparatus for an automotive vehicle, which can prevent a pillar garnish from scattering when an air bag installed in a front pillar portion is expanded, is provided. An air bag 16 is housed within a space formed by a front pillar main body 38 and a pillar garnish 40 in a front pillar portion 20. When the air bag 16 expands, the pillar garnish 40 is pressed by an expanding pressure of the air bag 16, so that an opening for expanding the air bag 16 is formed between the front pillar main body 38 and the pillar garnish 40, and the air bag 16 expands into a vehicle cabin through the opening. Since a non-expanding portion is formed at the air bag 16 and a hinge portion 46 is formed at the pillar garnish 40, the expanding pressure applied to the pillar garnish 40 when the air bag 16 expand is low, so that the pillar garnish 40 can be easily opened through the hinge portion 46.

Patent CA-2258834-A1 (CA)
Title: Pull-out lavatory
Inventor: MARTY GARRY R
IPC: E03C1/04
Filed: 1992-01-03
Abstract: A pull-out lavatory is disclosed wherein a spout may be removed from a sink top to direct a stream of water to a desired location.  The spout is mounted laterally offset from a lateral center of the sink top, and is firmly seated in the sink top when mounted.  The spout is guided out of its seat on the sink top by rotating the spout which is moved vertically upwardly out of its mount.  An arrangement prevents the spout from being rotated away from the center of the sink, since that may result in the stream of water being directed outwardly of the sink.  In a further aspect of the present invention, the spout includes upper and under cover members which are snapped together and which include mating rib and notch structure to add to the stability of the spout.  Also, the fluid connections within the spout housing include mounting structure that ensure they are properly aligned relative to the spout housing.  The overall combination results in a pull-out lavatory that may be quickly assembled and properly aligned.  Further, the inventive pull-out lavatory ensures that the spout is not inadvertently rotated in a direction such that a stream of water is directed outwardly of the sink.

Abstract: In order to avoid mechanical assembly problems and transmission of undersired electrical currents among circuit cards or boards in a telecommunications swich or similar digital device, a conventional hard-wired midplane bus is replaced by a wireless bus. The wireless bus includes a radio frequency or light wave transceiver on each card. Antennas on respective cards can either be oriented within direct line-of-sight of each other, or can project into a waveguide which directs the transmitted signals past all the other antennas. For example, the waveguide may be a metal enclosure which surrounds all the cards. Alternatively, respective aligned apertures in the cards can define a continuous transmission path. A data rate exceeding 1 megabit per second and a transmission power on the order of 1 milliWatt are preferred, since the bus is intended for use within a single switch housing.      Radio frequencies in the middle to high microwave range of light frequencies in the visible range are preferred, to provide sufficient bandwidth and to facillitate servicing.

Filed: 1999-06-09
Abstract: A non-destructive method of measuring physical characteristics of a medium, such as uncemented sediment, sandstone, or limestone. A pseudo-random code is generated and is used to generate a pseudo-random acoustic signal. This signal is transmitted into the medium to be measured through the use of a transducer, such as a piezoelectric element, and is received by a plurality of hydrophones. The received signal is then processed to obtain an image of its velocity and attenuation. A  universal geoacoustic model of the medium for a given set of measured data is determined, and the model is solved to obtain a pair of permeability-porosity results for the medium. The one of this pair of permeability-porosity results which is correctly indicative of the physical characteristics of the medium is then determined.
