| 20130306331 | PACKING ELEMENT BACKUP SYSTEM - Downhole tool packing element systems comprise a sealing element having a support system. The support system can include one or more of a first spacer ring, a second spacer ring, a third spacer ring, a mesh ring, and one or more petal rings. One or more of these components can be disposed at one or both of the upper end and/or lower end of the sealing element. When compressed, the sealing element is moved radially outward to engage an inner wall surface of a wellbore due to compressive forces of the one or more spacer ring(s), mesh ring, and/or petal ring(s). In certain embodiments, the lower end of one or more of the mesh ring(s) and/or petal ring(s) rotate outwardly toward the casing and, in certain embodiments, engage the casing to facilitate creation of the seal. | 11-21-2013 |
| 20150021048 | SLIP, TANGENTIAL SLIP SYSTEM HAVING SLIP, AND METHOD THEREOF - A slip for a tangentially loaded retrievable slip system. The slip includes a frame including an interior having first and second sides; and, a key having a first portion within the interior of the frame. The first portion having first and second sides. The first portion of the key movable within the interior of the frame; wherein the key is movable from a set condition with at least a contact point of the first and second sides of the first portion of the key pushing against at least a portion of the first and second sides of the interior of the frame in the set condition. Respectively, to an unset condition with the first and second sides of the first portion of the key releasing pressure from the first and second sides of the interior of the frame. Also included is a method of managing a tangential load imparted by a tangential slip system. | 01-22-2015 |

| 20150313433 | FLOOR SCRUBBING MACHINE - A floor scrubbing machine includes a footing that supports at least one brush, which can be actuated rotationally by an actuation assembly. The machine further includes at least one device for dispensing a washing liquid, a squeegee arranged to the rear of the brush, and at least one device for aspirating from the floor the washing liquid and the dirt removed by the brush. Additionally, the machine includes a pair of box-like bodies, each of which forms a respective tank for containing a liquid processed by the machine. The box-like bodies are stacked on each other on the footing. Removable retention elements are provided which act between the footing and the box-like body that lies above the other box-like body in order to retain the box-like bodies against each other and against the footing. | 11-05-2015 |
| 20150313434 | FLOOR CLEANING MACHINE, PARTICULARLY FOR HOUSEHOLD USE - A floor cleaning machine, particularly for household use, includes a box-like body that defines a compartment for accommodating a cylindrical brush that has a horizontal axis. The compartment has, at one end, an access opening that can be closed by means of a closure door that has a rim adapted to engage, by interlocking, the rim of the access opening Elastic pusher elements are provided that act on the closure door in order to facilitate its disengagement from the access opening and elements for the removable locking of the closure door in the condition for closing the access opening | 11-05-2015 |
| 20150313436 | FLOOR SCRUBBING MACHINE - A floor scrubbing machine for household use includes a box-like base structure that can move on a floor to be cleaned and accommodates at least one nozzle for dispensing a washing liquid and at least one rotating brush. The machine further includes at least one squeegee, arranged to the rear of the brush along a forward travel direction of the machine, and at least one intake, which cooperates with the squeegee for drying the floor. A rod-like handle is connected to the box-like base structure and can be tilted with respect to the floor in order to move the box-like base structure on the floor. The handle is connected to the box-like base structure by way of articulation elements adapted to transmit to the box-like base structure a rotation about an axis that is substantially perpendicular to the floor following a rotation imparted to the handle about its own axis. | 11-05-2015 |
| 20150313437 | FLOOR CLEANING MACHINE - A floor cleaning machine includes a supporting structure that has, along a forward travel direction of the machine, a front part and a rear part and supports a brush, which can be actuated rotationally, about a rotation axis that is arranged substantially vertically in use. The machine also includes a squeegee located in a rear position with respect to the brush along the forward travel direction of the machine The squeegee is mounted rotatably about an oscillation axis that is substantially parallel to the rotation axis of the brush. Connection elements are provided which can be activated on command and are adapted to couple rigidly the squeegee to the brush in its rotation about the rotation axis, in order to move the squeegee from the rear position to a forward position with respect to the brush, along the forward travel direction of the machine | 11-05-2015 |

| 20100034732 | Hydrogen production method - A method of producing hydrogen is provided that includes exposing a hydrogen-extracting (H-x) material to water, where the H-x material includes a crystal structure having interstitial space available for the insertion of protons and the water can be liquid water or vapor water. A spontaneous electrochemical reaction occurs, whereby water chemically decomposes in contact with the H-x material, the resulting hydrogen is stored in the H-x material and the resulting oxygen is emitted as a gas. This reaction proceeds until it is limited by a hydrogen loading capacity of the H-x material and/or the electrochemical potential of the H-x material relative to the water. The H-x material is heated to recover the stored hydrogen in a temperature range of 20 to 1000 degrees Celsius. This process is reversible, as it can be repeated many times. No electricity or consumable chemicals are required. | 02-11-2010 |
| 20110151290 | CRYSTALLINE-AMORPHOUS NANOWIRES FOR BATTERY ELECTRODES - Electrodes, batteries, methods for use and manufacturing are implemented to provide ion-based electrical power sources and related devices. Consistent with one such method, a battery electrode is produced having nanowires of a first material. The electrode is produced using a single growth condition to promote growth of crystalline nanowires on a conductive substrate and of the first material, and promote, by maintaining the growth condition, growth of an amorphous portion that surrounds the crystalline nanowires. | 06-23-2011 |
| 20150295229 | ORGANIC ACTIVE MATERIALS FOR ELECTROCHEMICAL ENERGY STORAGE - A compound having the structure Red-R-M, wherein: Red is a redox center; R is a bridging group; and M is a monomer giving rise to an electronically conductive polymer, is provided. Also provides are polymers obtained by polymerization of such compounds and uses in electronic devices of such polymers, for example uses in batteries. | 10-15-2015 |
