Inventor: MCLEOD CHRISTOPHER A
IPC: E03C1/22
Filed: 2012-10-04
Abstract: A drain closure device for a vessel such as a bathtub or sink is provided. The drain closure device comprises a stopper fitted with a sealing gasket and threaded onto a stem slidably mounted in a guide member which is in turn threaded into a strainer mounted in a hole in the bottom of the vessel. The device is concentrically disposed within the strainer. Twirling of the stopper causes the stem to rise and fall against an undulating cam surface of the guide. Resistance to closure is provided by rest stops for projections on the upper part of the stem. No spring, pins, or resistance seals are used. Once in place, the drain closure nests in the strainer.

Abstract: A strap having increased column stiffness includes a leading edge and a trailing edge forming a length of the strap, a first outer edge and second outer edge defining a width of the strap, and a first side and a second side defining a thickness of the strap. A crush region is formed in the first or second side, between and generally parallel to the first and second outer edges. The crush region is defined by a thickness that is less than the thickness of the strap adjacent to the crush region. The crush region forms a line along which a bend may be formed in the strap. The bend increases the column stiffness of the strap at least about 67 percent over that of a comparable flat strap. The bend defines an acute angle and an obtuse angle in the strap as viewed in cross-section.

Abstract: A high expansion plug has multiple sealing elements and an extrusion barrier system that uses overlapping petals in a stack of rings. When setting the plug, the petals are elastically moved toward a surrounding tubular wall in an elastic deformation between a housing that surrounds the mandrel and a tapered ring on the mandrel. That sandwich controls the amount of deformation and allows a potential energy force to be stored in the petals that allows them to return toward their initial position when the set of the plug is released and the seals are allowed to relax and extend axially as they shrink radially. The plug can then be removed without milling. Expansions in the order of 25% of the initial seal dimension are contemplated.

Inventor: FLEGAL MICHAEL JAMES
IPC: B03B9/02
Filed: 2013-04-02
Abstract: A single solvent method and machine for separating bitumen from oil sand ore are disclosed. The method includes the use of a single light paraffinic solvent, such as propane or butane as the agent to separate the bitumen from mined oil sand ore. Since light paraffinic solvents are vapors at atmospheric pressure and temperatures, the ore is placed in a pressurized container so that the solvent remains in a liquid state. When the container is pressurized, by the addition of the solvent itself, the liquid solvent is mixed with the ore to effect separation. The proposed machine settles more than 80% of the solids out under gravity in a modest period of time. The solvent - bitumen mixture is drained after the cleaning cycle, the container is depressured to a vapor recovery system and the remaining solids dumped out. The fine solids, drained with the liquids, are separated from the liquid mixture with relative ease by the use of current technology in other downstream equipment.

Abstract: The present invention teaches a film having a pattern of protruding structures.  When used in the vacuum packaging bag material context, the result is a vacuum packaging bag that a consumer can effectively evacuate and hermetically seal.  The protruding structures tend to form channels that enable gas to evacuate from within a vacuum packaging bag. In certain embodiments, the protruding structures are formed only on an inner side of the vacuum packaging film, typically through a hot casting or heat-extrusion process. As a result, far less bag material is required than in the prior art patterned film formed through cold embossing processes. The present invention also contemplates a variety of applications for the films, including preformed bags and bag rolls, as well as a variety of apparatus for manufacturing the films and appliances for utilizing the bags and bag rolls.

Abstract: Techniques for dynamically assigning acknowledgement (ACK) resource to a user equipment (UE) are described. For dynamic scheduling, a scheduling message may be used to send scheduling information for a single transmission of data. For semi-persistent scheduling, a scheduling message may be used to send a semi-persistent assignment for multiple transmissions of data. In an aspect, at least one field of a scheduling message, which is normally used to carry scheduling information for dynamic scheduling, may be re-used to carry an ACK resource assignment for semi-persistent scheduling. In one design, a UE may receive a scheduling message carrying a semi-persistent assignment and may obtain an assignment of ACK resource from the at least one field of the scheduling message. The UE may receive a transmission of data sent in accordance with the semi-persistent assignment, determine ACK information for the transmission of data, and send the ACK information with the ACK resource.

In addition, a UE performs a method for MBMS service area location update in the 3GPP compliant system. Accordingly, the UE: determines a 3GPP MBMS service area in which the UE is currently located; and identifies the 3GPP MBMS service area to an infrastructure device.
