Patent CA-2228167-A1 (CA)
Title: Polymer bearing seal and sealed bearing
Inventor: WASKIEWICZ WALTER P
IPC: F16C33/78
Filed: 1998-01-29
Abstract: A polymer ring has a circumferential mounting flange and an annular end wall extending radially inwardly and axially inwardly therefrom, providing a conically convex side and a conically concave side. An annular seal lip projects from a radially inner portion of the end wall to engage an annular radially outwardly curved surface of the bearing inner ring after insertion of the seal into the bearing. An annular rib located on the convex side between the end wall and the mounting flange, and an annular rib groove on the concave side opposite the annular rib, allow the polymer ring to collapse radially as the end wall is deflected axially outwardly to a more radial orientation during insertion.

Title: Synthesis and use of retinoid compounds having negative hormone and/or antagonist activities
Inventor: TENG MIN
IPC: A61K31/15
Filed: 1996-08-23
Abstract: Aryl-substituted and aryl and (3-oxo-I-propenyl)-substituted benzopyran, benzothiopyran, 1,2-dihydroquinoline, and 5,6-dihydronaphthalene derivatives have retinoid negative hormone and/or antagonist-like biological activities. The invented RAR antagonists can be administered to mammals, including humans, for the purpose of preventing or diminishing action of RAR agonists on the bound receptor sites.     Specifically, the RAR agonists are administered or coadministered with retinoid drugs to prevent or ameliorate toxicity or side effects caused by retinoids or vitamin A or vitamin A precursors. The retinoid negative hormones can be used to potentiate the activities of other retinoids and nuclear receptor agonists. For example, the retinoid negative hormone called AGN 193109 effectively increased the effectiveness of other retinoids and steroid hormones in in vitro transactivation assays. Additionally, transactivation assays can be used to identify compounds having negative hormone activity. These assays are based on the ability of negative hormones to down-regulate the activity of chimeric retinoid receptors engineered to possess a constitutive transcription activator domain.

Abstract: L'invention concerne des structures d'emballage transparentes pour fruits ou légumes liquides ou semi-liquides dont la couche polyamide en contact avec les aliments a une épaisseur d'au moins 0,4 millième de pouce et prolonge la durée de vie des couleurs du produit alimentaire recouvert. La couche polyamide élimine certains produits de dégradation de composés polyphénoliques qui sinon provoqueraient le brunissage durant le stockage. Les structures d'emballage permettent de voir clairement les produits contenus et leurs couleurs grâce à un film ou une matière structurale en feuille transparent comportant une couche superficielle en polyamide, la matière structurale étant transformée en une structure d'emballage. Cette structure d'emballage peut être un sachet sous forme de film ou une bouteille en plastique, la couche superficielle du film ou de la feuille formant la couche de la surface interne en contact avec les aliments de la structure d'emballage. Selon une variante, il est possible d'utiliser une couche polyamide à contact interne de recouvrement d'une structure d'emballage transparente, la partie réceptacle même ne nécessitant pas, dans ce cas, de couche polyamide à contact interne.

Abstract: A rotor (1) is of a substantially spherical shape with one complete half of the sphere (2) still remaining. The rotor (1) effectively takes the shape of the head of a "mushroom". The other half of the sphere has had its material removed or omitted forming the stem (3). The depth of the cut "D" and the length "L", the radius of the sphere, will determine the ratio of the respective weights of the complete half sphere (2) and the stem portion (3). Suitably the weight of the one half to the other half of the spherical body is between .75 and .85 and more preferably .8. When an external force is applied to the rotor (1) it rotates about a pair of orthogonal axes one of which is defined by the edge (6) of the spherical body between the two halves.

Patent CA-2258024-A1 (CA)
Inventor: HENDRY JAMES WATSON
IPC: B29C45/26
Filed: 1998-04-08
Abstract: An improved method and injection molding system are provided for making a hollow plastic article wherein plastic resin is injected into an article-defining cavity so that the cavity is loosely filled but not filled to capacity with the plastic resin and wherein the article is defined within the cavity. At this time, the plastic resin has an undulating surface. Then, pressurized gas is injected into the plastic resin in the loosely filled cavity to distribute the plastic resin in the cavity and convert the undulating surface into a surface defined by the cavity, thereby forming at least one gas hole within the distributed plastic. Preferably, the plastic resin occupies approximately 92 % to 99 % of the volume of the cavity immediately after injecting the plastic resin. Preferably, the plastic resin in the cavity is sensed by a sensor during plastic resin injection to generate a signal for use by a hydraulic control system of the injection molding system to stop linear movement of a screw ram of the injection molding system. The sensor may be an infrared sensor assembly including an optical fiber bundle which defines a portion of the cavity. Alternatively, the sensor may be a pressure sensor, which also may define a portion of the cavity. The sensor may also be either an ultrasonic sensor or an electromagnetic sensor.
