Title: Separation d'hydrocarbures et d'eau de melanges les contenant
Inventor: ARTHUR RONALD WILLIAM
IPC: C10M175/04
Filed: 1996-05-22
Abstract: L'invention porte sur un procédé ainsi que sur un appareil permettant de séparer un hydrocarbure (notamment de l'huile) et de l'eau de mélanges les contenant. Le procédé consiste à faire traverser au mélange une masse filtrante telle qu'un lit fluidisé (20) dans une cuve verticale de forme allongée (10) divisée en trois chambres (13, 14 et 15) par des tamis (16a et 16b), la chambre 14 comportant le lit fluidisé. Celui-ci contient des granulés (17) d'un polymère, du caoutchouc par exemple, en suspension dans un corps constitué d'eau, les granulés ayant été activés par une exposition à une substance telle qu'un alcool ou une substance à base d'alcool, ce qui a pour effet de les rendre hydrophiles. De ce fait, le mélange s'écoulant dans la cuve depuis une canalisation d'admission (18), entre en contact avec les granulés et une forte proportion de l'huile s'y trouvant contenue se trouve retenue par ceux-ci et, partant, est séparée de l'eau qui, à son tour, s'évacue de la cuve par une canalisation d'évacuation (22).

Title: Retractable mooring line device
Inventor: GORDON LESLEA C
IPC: B66D1/30
Filed: 2003-03-18
Abstract: A retractable mooring line device comprising a reel for storing and paying off a mooring line (2), having side walls (22, 24) each comprising a series of notches (60) for receiving a releasable latch (54). A latch simultaneously engages between notches in both side walls (22, 24) at a substantially right angle to provide a secure, positive locking engagement between the latch and the reel while permitting the latch (54) to be released under the application of relatively little force. In the preferred embodiment the latch may be actuated by a user's hand or foot and is biased toward the reel by a spring (70) which bears against the housing (18). The mechanism can be exposed for maintenance or repair simply by removal of the gunnel plate (16) and reinstallation of the gunnel plate does not require special loading of the latch spring.

Abstract: L'invention concerne une méthode de diagnostic de maladies osseuses et/ou d'une sensibilité à celle-ci, chez un individu. La méthode consiste à cribler un échantillon biologique prélevé sur l'individu afin de détecter un ou plusieurs indicateurs génétiques de maladie osseuse dans ledit gène PTHrP de l'individu, et à effectuer un diagnostic sur l'individu à partir d'une caractérisation de l'indicateur/des indicateurs génétiques détectés. Un indicateur génétique de l'invention comprend de préférence un segment génétique d'un gène de PTHrP. Idéalement, un segment génétique d'un gène de PTHrP comprend une région contenant VNTR. L'invention concerne également un mammifère transgénique non humain destiné à l'étude de maladies osseuses et/ou d'états osseux, le mammifère présentant une interruption ou une inactivation d'un gène de PTHrP ou d'une partie de celui-ci, spécifiquement dans des cellules ostéoblastes.

Title: Tuyere traversante pourvue de goupilles de soupape pour moules en grappe
Inventor: RICK ROBERT
IPC: B29C45/32
Filed: 2003-08-11
Abstract: L'invention concerne une tuyère traversante (10) comprenant deux parties (22, 24) qui, lorsqu'elles sont réunies, définissent un logement (20) à travers lequel s'étend un passage (30), un siège de soupape effilé (50) s'étendant autour dudit passage, ainsi qu'un élément soupape (60) comportant une tête de soupape effilée (62) qui est disposée dans ledit passage pour venir au contact du siège de soupape (50). Les deux parties peuvent être séparées axialement au niveau d'une interface s'étendant à travers le siège de soupape/la tête de soupape. Pour ouvrir la soupape, les deux parties de soupape (64, 66) sont tout d'abord réunies, puis déplacées conjointement et solidairement, dans la même direction par rapport au logement (20), pour être mises à une distance axiale du siège de soupape. De manière analogue, les éléments soupape sont déplacés de manière solidaire pour entrer en contact avec le siège de soupape avant la séparation de la tuyère traversante. Ainsi, contrairement à ce qui se passe dans un mode de réalisation faisant appel à des obturateurs de soupape, l'interface de soupape (68) entre les deux parties de la tête de soupape n'est pas exposée à de la résine fondue, ce qui empêche le piégeage de résine fondu entre lesdites deux parties et, par conséquent, la formation d'un cordon lors de l'ouverture du moule.

Filed: 1990-06-12
Abstract: ABSTRACT     In an overhead optical transmission system in which an optical cable is freely supported between towers employed to support overhead electric power transmission lines and in which each end of the suspended length of optical cable is secured to a tower by means of a metal termination fitting which surrounds and is clamped on a part of a length of the optical cable at or near this end, each metal termination fitting of the cable over a part of the length of the fitting extending to the end of the fitting remote from the tower and an immediately adjacent part of the length of the optical cable are surrounded by a shield of an electrically conductive metal or of a semi-conductive plastics material sufficiently conductive to reduce arcing and/or joule heating.  Preferably, a preformed helix constituting a damper extends lengthwise of the shield and may extend lengthwise of the part of the length of the fitting, the overall outer diameter of the preformed helix over a part of its length remote from the fitting increasing smoothly in a direction away from the fitting.  Where the shield is a preformed helix of a semi-conductive plastics material, the preformed helix may be so shaped over a part of its length remote from the fitting that the preformed helix serves the dual purposes of a shield and a damper.

IPC: B28B19/00
Filed: 1990-07-11
Abstract: The  invention relates  to a method and apparatus  for making  concrete  pipe  having  vinyl  liners.    The  method involves the use of an expandable core to hold a vinyl liner and a forming module.  The core comprises an expandable shell which can be deformed by the forming module into an exact desired shape prior to placing the concrete around the core.          First, a vinyl liner is placed on the core.   The liner and core are inserted along with reinforcing into a dry-cast concrete form.   Then, the form is placed on the module and the  module  is  actuated  into  engagement  with  the  inside surface of the core.   The form is filled and immediately taken off of the module.  The form is immediately stripped, but the core continues to hold the liner in engagement with the concrete until a complete bond is established.  Finally, the core is retracted and removed from the finished lined pipe.

Title: Bar code symbol readers with edge enhancement
Inventor: METLITSKY BORIS
IPC: G06K7/10
Filed: 1990-09-27
Abstract: ABSTRACT OF THE DISCLOSURE      The depth of modulation of an analog electrical signal generated by a photodetector during scanning of a bar code symbol in the field of bar code scanning is enhanced under circumstances where the modulation of the analog signal has been degraded, for example, by an oversized sampling aperture in relation to the widths of the symbol elements. The analog signal has high frequency components whose Low amplitudes are increased in magnitude prior to being conducted to a digitizer. The effect of noise introduced during reading of the bar code is cancelled by comparing in the comparator, the modulation-enhanced analog signal with the second derivative signal derived from the modulation-degraded unenhanced analog signal.  The output of the comparator is a  digital  output  signal  having  a  logical  level dependent  on  the  amplitude  of  the  enhanced  analog signal at each zero crossing of the second derivative signal.    The  digital  output  signal  is  a  closer representation of the code read by the scanner.
