Title: Oral treatment compositions and related methods of manufacture
Inventor: SOLIZ DEBRA C
IPC: A61K8/22
Filed: 2009-02-20
Abstract: An oral treatment composition that includes a carrier, an active agent and a silicon dioxide compound. The active agent can be a variety of compositions, such as dental whitening or bleaching agents, desensitizing agents, antimicrobials, anti-plaque agents, remineralizing agents, anti-tartar agents, mouth fresheners, and anesthetics. Optionally, a processing aid can be added to the composition to streamline manufacture of the gel.

Abstract: A valve assembly for controlling the flow of pressurized fluid supplied t o an actuating cylinder having a piston driven by the pressurized fluid alon g a stroke path therewithin, the pressurized fluid being applied to alternat ive driving sides of the piston. The valve assembly comprises a first and a second valve pistons, which cooperate to block the supply of pressurized flu id to the current driving side of the piston when the piston reaches the end of its stroke path, thereby limiting the pressure of the pressurized fluid supplied to the driving side to a level reduced compared to a pressure level applied to drive said piston. If a leak occurs within the actuating cylinde r at the end of the stroke path of the piston, it will be at the reduced pre ssurized fluid pressure.

IPC: G06Q20/40
Filed: 2009-06-12
Abstract: A system and method for authorizing transfers via mobile devices are provided. The system includes a first mobile device and a server. The first mobile device executes a transfer authorization application that allows a user to enter transfer information for a transfer. In response, the transfer authorization application generates and communicates a transfer request for the transfer.

Title: Quick-connect structure for quick connection of piping elements
Inventor: XIE FRANK
IPC: F16L37/091
Filed: 2009-07-30
Abstract: The present invention provides a new-model quick-connect device for piping elements. It solves the problem of difficult disassembly, poor sealing and easy occurrence of leakage in quick-connect structures for piping elements. In one embodiment, the new-model quick-connect device for piping elements of the present invention comprises a main body having an interior surface defining a connecting hole, and the main body can connect with a connecting tube inserted into the connecting hole. An annular groove is provided in the inner surface of the main body defining the connecting hole, and a sealing washer that can form an air-tight or fluid-tight seal with the inserted connecting tube is embedded in the annular groove. Located radially outwardly of the sealing washer is a clamping ring that can connect with the connecting tube. The connecting ring has a plurality of jack catches that incline toward the inside of the connecting hole. When the tube or piping is inserted, the clamping ring grips the tubular member, providing increased opposing force to prevent disconnection. Radially outwardly of the clamping ring, there is an annular socket which can push away the jack catches when the clamping washer is pushed against the inner surface defining the connecting hole. The present invention is reliable to use, versatile and convenient, has a high sealing performance and can be used for temporary or permanent connections.

Patent CA-2677016-A1 (CA)
Title: Double drag wind rotor
Inventor: HOFMAN JEAN PIERRE
IPC: F03D3/00
Filed: 2009-08-28
Abstract: The invention describes a Wind Collector, referred to as the Drag Rotor, based on the air resistance, called the Drag, which is engendered by the foil surface of its body. In the wind industry, Rotors function as transformers of wind power into rotational motion, where stabilized velocity is primarily significant. In the Wind-Hydro Generator Process, referred to as the Process, and developed in a separate patent application, this rotation of the Drag Rotors transmits a torque, which turns a shaft, which actuates a Hydraulic Generator (pump, or motor or turbine acting like a pump), and converts the wind energy into kinetic force of a water flow (See Figure 6d). Drag Rotors preferably are coupled (see Figure 1) to enhance the wind power collection by using a common central deflector which enables minimizing any potential "negative drag". However a Drag Rotor may be exploited in single structure, using either a vertical or horizontal axis and according to the location where it is to be installed (e.g.  on the roof of a building where a horizontal positioning would be more user friendly or conform to local regulations - see Figure la). Drag Rotors use sails shaped like an arc of a cylinder or using a spiral spine, with an off-centered axis of the central rotor versus the stator. One side of the sail is guided alongside the external circle (the Stator) while the other side swivels while turning with the central rotor wheel. This "off-centered" motion enables each sail to turn separately and differently from the others according to its position with the rotor's shaft. The sails being made of cloth enables varying the dimensions of the overall foil surface of the Drag Rotor simply by modifying the height or the width of the sails, like on sail boats, so that they offer only resistance to the wind as the user needs, (e.g. in storm conditions where it may be dropped entirely). Unlike conventional wind turbines, Drag Rotors may be considered as variable displacement devices.

Patent CA-2687517-A1 (CA)
Inventor: MALLADI DURGA PRASAD
IPC: H04L1/00
Filed: 2008-06-12
Abstract: Bits included in each code block of a transport block can be stored to an associated circular buffer and transmitted over a channel. Each circular buffer can vary in size in proportion to a size of the associated code block. Therefore, since in certain operating environments code blocks for a transport block can vary in size, circular buffers can vary in size as well. Accordingly, when not all data from a transport block and/or an array of circular buffers can be transmitted over the channel, each circular buffer from the array can transmit a portion of bits that is proportional to a size of the respective circular buffer (or the associated code block or encoded code block). Furthermore, the number of bits transmitted from each circular buffer can be constrained by an aggregate budget for all circular buffers and can be further constrained to be an integer multiple of a modulation order for the transport block.
