Title: Fastener driving tool having improved bearing and fastener guide assemblies
Inventor: HEMPFLING DAVE C
IPC: B25B23/10
Filed: 2001-12-28
Abstract: A fastener driving tool includes a driver having a driver shaft extending therefrom, a first extension member operably connected to the driver and a second extension member operably connected to the first extension member. The tool is for use on roof deck panels. The second extension member slidingly engages the first extension member between a loading position and a driving position. A bearing assembly operably connects the first and second extension members. The bearing assembly is formed from a non-metallic, low-friction material. A portion of the bearing assembly is mounted to one of the first and second extension members for sliding engagement with the other extension member and is disposed to prevent direct contact of the first and second extension members with one another. A fastener receiving member is mounted to the second extension member for receiving fasteners when in the loading position and for supporting and releasing the fasteners when in the driving position. The fastener receiving member includes a cradle having a main body portion and a pair of legs extending from the main body portion diverging downwardly and outwardly. The cradle is configured for positioning on the roof panel, straddling raised portions of the panel for aligning the tool therealong.

Abstract: An acid vanadium electrolyte solution containing V+3 and V+4 in a desired concentration ratio from solid vanadium pentoxide fed into the electrolyte solution, is produced by electrochemically reducing at least partly of the dissolved vanadium in the acid electrolyte solution by circulating the electrolyte solution through a plurality of electrolytic cells in cascade to  at least partly to a V+3 state; reacting the so reduced vanadium content in electrolyte solution outlet from the last of said electrolytic cells with a stoichiometric quantity of vanadium pentoxide obtaining an electrolyte solution containing vanadium substantially in a V+4; adding acid and water t o maintain a certain molarity of the solution; and continuously recycling the electrolyte solution through the cascade of electrolytic cells while bleedin g a stream of yielded electrolyte solution containing V+3 and V+4 in the desir ed concentrations at the exit of one of the cells of said cascade. Each cell is  highly asymmetric, having a cathode and an anode with respective surface morphologies, geometry and mutual disposition such to establish on the anode  surface a current density from 5 to 20 times greater than the current densit y on the projected cathode surface and evolve oxygen at the anode. An asymmetr ic cell of this type may be used in the circuit of one of the positive and negative electrolytes of a working battery for rebalancing the respective states of oxidation of their vanadium content.

Title: Oxidative desulfurization of fossil fuels with ultrasound
Inventor: MEI HAI
IPC: B01J19/10
Filed: 2001-09-24
Abstract: Fossil fuels are combined with a hydroperoxide in an aqueous-organic medium and subjected to ultrasound, with the effect of oxidizing the sulfur compounds in the fuels to sulfones. Due to their high polarity, the sulfones thus formed are readily removed from the fuels by polar extraction. The process is thus highly effective in removing sulfur compounds from the fuels.

Title: Bi-level flow generator
Inventor: SOUQUET JACQUES
IPC: A61M16/00
Filed: 2001-09-28
Abstract: An apparatus and method for treating sleep apnea includes a bilevel flow generator having an alternating current (AC) synchronous motor coupled to a low inertia centrifugal rotor/impeller. The process of acceleration and deceleration of the rotor involves moving from frequency A, amplitude A to frequency B, amplitude B in an optimal linear fashion using the so-called Bresenham algorithm. This is coupled with a tuned increase of the amplitude during the acceleration process which will produce the acceleration using minimum current allowing the use of smaller power supplies. During deceleration the process is accomplished in reverse fashion using a tuned decrease of the amplitude coupled with a special shunt circuit to prevent power supply voltage changes. These changes in amplitude overlay a current feedback mechanism used to prevent loss of synchronization of the motor by changing amplitude. Speed changes can also be timed so as to prevent desynchronization.
