Patent CA-2067512-A1 (CA)
Inventor: BIES SYLVESTER W
IPC: E06B3/78
Filed: 1992-04-29
Abstract: A door has a pair of spaced stiles at its side edges, a top rail extending between the upper ends of the rails, and a pair of synthetic resin skins providing the faces of the door and adhesively bonded to the stiles and rail.  The skins have opposed flanges along their top and bottom edges which abut to form top and bottom peripheral walls, and they also have opposing spaced lips along the side edges thereof which extend along a portion of the outer surfaces of the stiles.  The peripheral walls provided by the flanges have vent openings extending therethrough, and a cellular synthetic resin core is bonded to the skins and fills the interior space between the skins bounded by the stiles, rail and bottom flange.  baffled passages are provided between the vent openings and the interior space.  In making the door, after the skins have been assembled and adhered to the stiles and rails, the stiles and flanges effectively seal the interior space which they define and this assembly is placed in a heated press.  As a foamable resin mixture is injected under pressure into the interior space and expands therein, air is expelled through the baffled passages and vent openings, and the press precludes bowing outwardly of the skins.

Title: Process and catalyst for producing isotactic polyolefins
Inventor: EWEN JOHN A
IPC: C08F10/00
Filed: 1992-09-08
Abstract: This invention is for a metallocene catalyst component useful in preparing isotactic polyolefins, a catalyst system using this component and a process for polymerizing olefins using the catalyst component. The catalyst component consists of a bridged metallocene in which one of the cyclopentadienyl rings is substituted in a different manner from the other ring. One of the cyclopentadienyl ligands contains a bulky group in one and only one distal position and the other cyclopentadienyl ligand has bilateral or pseudobilateral symmetry. There is a steric difference between the two Cp rings.      The catalyst component is a stereorigid metallocene described by the formula:      R" (CpR n)(CpR'm)MeQ k wherein each Cp is a cyclopentadienyl or substituted cyclopenta-dienyl ring: each R n and R'm is a hydrocarbyl radical having 1-20 carbon atoms; R" is a structural bridge between the two Cp rings imparting stereorigidity to the Cp rings. Me is a transition metal; and each Q is a hydrocarbyl radical or is a halogen. R'm is selected so that (CpR'm) is a sterically different substituted cyclopentadienyl ring than (CpR'n). The use of a metallocene catalyst component with sterically different cyclopentadienyl rings in which one and only one of the distal positions of the cyclopentadienyl rings has a bulky group as a substituent produces isotactic polymer.

Title: Method for achieving high pressure using isotopically-pure diamond anvils
Inventor: BOVENKERK HAROLD P
IPC: G01N3/40
Filed: 1992-09-09
Abstract: METHOD FOR ACHIEVING HIGH PRESSURE USING    ISOTOPICALLY-PURE DIAMOND ANVILS   Broadly, the present invention is directed to a method for achieving high pressure wherein a sample is placed between a pair of diamond anvils and the anvils compressed. the improvement comprises forming the anvils from one or more of isotopically-pure 12C or 13C diamond. Isotopically-pure 13C diamond is preferred as it has die highest atomic or bond density parameter of any known material and, therefore, should have the highest hardness also Isotopically-enriched diamond 13C diamond should find utility as an anvil with higher 13C contents increasing the hardness of the anvil product. By utilizing isotopically pure diamond anvils, less breakage at current pressures should be realized concomitant with the ability to achieve yet higher pressures.

Title: Catalytic converter for use in hot exhaust gases and process for making it
Inventor: HUMS ERICH
IPC: B01J35/02
Filed: 1991-07-31
Abstract: Abstract In catalysts for use in hot exhaust gases with a surface-roughened metal bearing structure and a catalytically active coating applied thereto, there is the problem that the catalytically active coating can fall off the metal bearing structure. It is therefore the aim of the invention to improve the adhesion of the catalytically active substance to the bearing structure. To this end, according to the invention, the metal bearing structure is roughened by spark erosion. Then the catalytically active coating can be keyed to the metal bearing structure roughened by spark erosion with the aid of a cross linking agent. The invention is applicable to catal-ytically coated plate catalyst systems.

Abstract: DE L'INVENTION Pour faciliter la compréhension, nous vous référons à la page 1 de 1. Vous y voyez quatre figures, représentant une seule pièce, vue de trois positions différentes: fig. 1, une vue par en dessus; fig. 2, une vue de côté mais un peu surélevée; fig. 3, une vue à la hauteur de l'oeil; La fig. 4, est un médaillon, représentant une coupe du bordage d'un contenant à peinture, et, sur lequel apparaît une coupe de l'invention "cercle-couvercle". Sur chaque figure, les mêmes chiffres représentent la même partie de l'invention. L'invention actuelle se compose d'une seule pièce. Cependant, elle a comme trois composantes: une fait tenir l'invention au contenant, une autre protège la cavité contre l'accumulation de la peinture et, une dernière empêche la peinture de faire des coulisses quand on arrête de transvider. L'objet étant circulaire, pour l'explication, nous parlerons de circonférence. La circonférence (1) est moins grande que l'ouverture d'un contenant. Elle a pour but de permettre, par une pression des mains sur le cercle-couvercle, la pénétration de la circonférence (2) à l'intérieur de la bordure du contenant pour se coller à la partie interne et s'accrocher à la bordure tournée pour tenir en place le cercle-couvercle. La peinture ne pourra pas s'introduire par le dessous et atteindre la cavité à protéger. La peinture devra nécessairement passer par en dessus. A ce moment, la circonférence (3) devient un couvercle protecteur pour la cavité du contenant. La circonférence (4) va en montant si nous comparons à (3) pour que la peinture déposée sur (3) doivent nécessairement retomber à l'intérieur du contenant. La circonférence (5) est un sommet et la circonférence (6) va en descendant. Cette descente a pour but d'empêcher la peinture de faire des coulisses le long du contenant quand on arrête de transvider la peinture. Si l'on s'aide tant soi peu avec un pinceau en essuyant une trop grande abondance de peinture après versement, le tout peut rester très propre. Quand vient le temps de refermer le contenant, nous n'avons qu'à retirer le cercle couvercle et à y déposer aussitôt le couvercle d'origine puisque la cavité du contenant et son côté sont aussi propres qu'à l'ouverture. C'est une invention qui nous fera économiser du temps et nos produits. Par le fait même, en l'utilisant, nous protégerons notre environnement.

Abstract: Apparatus is provided for controlled cooling of thermoplastic strands between the time that they are extruded from a melt of thermoplastic material until they are cut into pellets by a pelletizer that pulls the strands into it.  A first tray inclined downwardly from the extruder receives the strands which are sprayed with cooling liquid while in the tray.  A second tray inclined upwardly from the bottom of the first tray toward the pelletizer receives the strands which are also sprayed while in the second tray.  Cooling liquid is also introduced at the inlet end of the first tray.  A gravity liquid removal screen is positioned at the low point of each tray to remove the cooling liquid from the trays.  A vacuum system for removing cooling liquid from the strands may also be positioned between the higher end of the second tray and the pelletizer.  The temperature and quantity of the cooling liquid sprayed on the first tray, that sprayed on the second tray, and that introduced at the inlet end of the first tray are individually controlled by a cooling liquid control system utilizing a programmable central micro-processor.
