Title: Spill inhibiting spout
Inventor: MESSNER MARVIN
IPC: B65D25/48
Filed: 1999-04-06
Granted: 2003-03-11
Abstract: A spout for mounting on a liquid container to provide controlled dispensing of liquid therefrom includes a manual control for stopping the flow of liquid through a pouring tube and an automatic control to prevent spills due to overfilling. Manual control over the amount of liquid flowing through the pouring opening of the spout is provided by a preferably tubular rod having a stop mounted at one end and a push button actuator at the other end of the rod. The spout includes a body with the pouring tube extending from one side and the push button for opening the stop to dispense liquid on the other side of the body. The automatic control is provided through a vent tube which extends through a port in the pouring tube and is connected to the tubular rod which is provided with at least one hole. When the level of liquid in a receiving tank rises over the port, no air enters the liquid container and consequently the flow of liquid from the pouring tube is discontinued.

Title: Steering of internet access to sponsors
Inventor: LIN ARTHUR
IPC: G06Q30/00
Filed: 2000-01-06
Granted: 2010-07-13
Abstract: This invention provides an Internet Access Provider (IAP), a simple mechanism to steer users to given Internet services, such as the Web pages, of sponsors. The mechanism allows a sponsor to grant a dial-in user unlimited access to the Internet after the user has first accessed its Internet services. The invention is thus important for any IAP that wants to receive income from sponsors by steering Internet users to their services. In the ultimate case, an IAP could receive all its income from sponsors and thus be able to offer the Internet access for free. The key characteristics of the present invention is that a user is steered to the Internet services of a sponsor based on a sponsor specific called telephone number or a sponsor specific login name. The IAP does not need to uniquely identify the user and therefore no user specific PINs are needed. Sponsors can simply promote their offers by publicly advertising their sponsor specific Internet access telephone numbers or login names. The user registration process (if any) and the determination of when unlimited access should be granted is handled by the sponsor. The functions of the IAP are sponsor independent and the amount of information that needs to be transferred between the sponsor and the IAP is minimized.

Abstract: A stereospecific method for accomplishing the below reaction: (see formula I) results in the compound of formula 2 having the same stereochemistry at both carbon 1 and carbon 3 as that in the compound of formula 1. Thus, if carbon 3 is in the R-configuration in the compound of formula 1, then carbon 3 will be in the R-configuration in the compound of resulting formula 2. In the above process, R1 is C1-C6 alkyl that can be straight-chain or branched. The process functions using a fluorinated alcohol having a pK a less than about 9, in the presence of a palladium catalyst. The compounds of formula 1, as well as novel intermediates in this process, are useful in manufacturing vitamin D analogs.

Abstract: This disclosure relates to egg yolk compositions with improved functionality as well as methods of preparing such egg yolk compositions. Such egg yolk compositions confer improved functionality to the food products into which they are incorporated. The egg yolk compositions are prepared by a process comprising: (1) forming an aqueous egg yolk mixture; (2) adding an alkaline material to the aqueous egg yolk mixture in an amount sufficient to adjust the pH of the aqueous egg yolk mixture to about 7.5 or above; (3) heating the pH-adjusted aqueous egg yolk mixture to about 40 to about 80°C for a period of about 30 minutes or longer; (4) cooling the heat treated aqueous egg yolk mixture to or close to ambient temperatures; and (5) added an acidic material to the cooled aqueous egg yolk mixture to adjust the cooled aqueous egg yolk mixture to a neutral pH, thereby forming the aqueous egg yolk composition; wherein the aqueous egg yolk composition can be used in food compositions to impart improved egg yolk functionality. The use of the compositions and methods of the disclosure lead to the use of less egg yolk, oil, and/or other ingredients in the food compositions described herein, thereby reducing the cost of producing large quantities of such food products. Such reductions in cost could be translated to the general public, and thereby serve the consumer.

Title: Compositions topiques comprenant un analgesique opioide et un antagoniste du n-methyl-d-aspartate (nmda)

Abstract: On a développé un paradigme opioïde topique permettant de déterminer les effets périphériques analgésiques de la morphine. La morphine topique ainsi que des peptides tels que [D-Ala2-MePhe4,Gly(ol)5]enképhaline (DAMGO) ont produit une analgésie efficace dose-dépendante au moyen d'un test "tailflick" à chaleur radiante. Les médicaments topiques ont potentialisés des agents sytémiques, d'une manière similaire à la synergie établie antérieurement entre les sites d'action centraux et périphériques. Une tolérance locale à la morphine a été rapidement produite par une exposition topique à la morphine répétée quotidiennement. La tolérance à la morphine topique a été bloquée efficacement par l'antagoniste MK801 des récepteurs de N-méthyle-D-aspartate (NMDA) et une kétamine donnée soit par voie générale soit localement. Les antagonistes du récepteur du NMDA ont inversés la tolérance à la morphine préexistante. L'activité des antagonistes topiques du NMDA, permettant de bloquer la tolérance à la morphine, montre que les récepteurs périphériques du NMDA sont des médiateurs de la tolérance locale à la morphine. La morphine présente une tolérance croisée avec la [D-Ala2-MePhe4,Gly(ol)5]enképhaline (DAMGO), mais pas avec la morphine-6 beta -glucuronide, ce qui implique des mécanismes d'action différents. Ces observations sont de grande importance dans la conception et l'utilisation clinique des opioides. L'invention concerne également des compositions pharmaceutiques topiques comprenant un analgésique qui agit par l'intermédiaire d'un récepteur opiacé et un antagoniste du récepteur du NMDA permettant de produire un analgésique sans induire une tolérance.

Abstract: An architectural covering, such as a blind, for use primarily over windows and doorways, includes of a plurality of separate composite vanes made of an opaque rigid material and a sheer material, if desired. Each composite vane can be manufactured as a flat, rollable laminated assembly of strips and joined or bonded at least substantially on a line along the length of the strip and substantially along one edge of one strip. Several different embodiments of the composite vane are disclosed. In one embodiment, the composite vane comprises a generally flat, unexpanded opaque material with individual pieces of sheer material attached to an edge of the vane. In another embodiment, a laminated composite vane comprises a pair of strips with the transverse width of one strip greater than the other strip to form a torque tube when edge-joining the strips. In yet another embodiment, the laminated composite vane includes a pair of strips of substantially equal width with a resilient insert strip having a non-flat cross section inserted into the torque tube. The resilient insert strip can assume a flat transverse form, but return elastically to the predetermined cross-sectional shape when removed from the roll or be inserted after each vane is cut to its final length. Any combination of the above-mentioned embodiments is possible to connect single or double sheets of sheer material to the edges of the vanes while enabling the vanes to be oriented vertically or horizontally.
