Abstract: A downhole drilling efficiency sensor (DES) apparatus for use with drilling operations in oil and gas exploration, that accurately measures important drilling parameters at or near the drill bit in order to increase the effectiveness and productivity of the drilling operation.  The parameters measured include weight-on-bit (WOB), torque-on-bit (TOB), bending-on-bit (BOB), annulus pressure, internal bore pressure, triaxial vibration (DDS - drilling dynamics sensor), annulus temperature, load cells (10a, 10c) temperature, and drill collar wall (8) inside diameter temperature of a drill string (12). The direction of the bending-on-bit measurement is also determined with respect to the low side of the hole while rotating (or stationary) by using a triaxial vibration sensor and magnetometer array (72). The device combines sensors (74), temperature readings and other sensors capable of collectin all the indicated parameters, for presenting them to the drilling operator such that an accurate views of the downhole drilling parameters, as thermally isolated (66) from thermal effects of borehole fluid (66) are obtained via side wall readout (64).

Abstract: The mechanical digital shaft is as integral part of the "MECHANICAL      DIGITAL GEAR", (U.S. Patent application file # 09/696301). In conjunction with the (PCU), it is a method of converting rotary motion into controllable reciprocating motion and visa versa. Gear teeth reciprocate with in the shaft to mesh and un-mesh with the teeth on the "mechanical digital gear track." The mechanical digital shaft can have from 1-3 teeth that can reciprocate, and can be at zero degrees, at one hundred and eighty degrees, at one hundred and twenty degrees. The shaft case rotate in any direction. The teeth reciprocate, either hydraulically or pneumatically. The pressure is controlled by the "PCU". When the teeth are engaged the pressure is high.

Abstract: This invention relates to an apparatus and method that can provide a group of individuals with an experiential exercise. The apparatus can comprise a source of fluid flow and a channel formation connected to the source of fluid flow at at least two regions of the channel formation. The source of fluid flow can be a vacuum suction provided from, for example, a single vacuum source. The fluid flow can be airflow. The channel formation is adapted to receive at least one projectile therein, and the projectile is displaceable within the channel formation as a result of the fluid flow. The projectile can be, for example, a ball. A gate is located at each region and is movable between an open position and a closed position. When the gate is in the closed position it at least partially obstructs the fluid flow with the channel formation in that region. Further, at least one fluid flow regulator is provided in the channel formation to adjust the fluid flow in the channel formation.

Title: Cord rewinder for a water filter type vacuum cleaner
Inventor: LOWERY VERNON
IPC: A47L9/26
Filed: 2000-02-16
Abstract: A cord rewinder assembly (12) for a wet vacuum cleaner (10) with a moist air discharge outlet includes a conventional cord rewinder (22) and a deflector plate (20). The deflector plate (20) not only shields the cord rewinder (22) from di-rect contact with the moist airflow dis-charge, but also functions to remove mois-ture from the airflow so that it can be uti-lized to cool the electrical components of the cord rewinder (22). Incoming air is cleaned by a water canister and filters. The clean moist discharge air impinges on the deflector plate (20) and redirected down-wardly toward a cavity (62). The airflow passes beneath the deflector plate (20) and reverses direction. The decrease in veloc-ity and redirection allows the moisture to drop out of the airflow. The dry airflow is directed through the cord rewinder (22) to remove heat generated by electrical com-ponents thereof. The heated airflow is then exhausted through a vent with a removable cover.

Title: High dispersion fibers for high-speed transmission
Inventor: ESSIAMBRE RENE-JEAN
IPC: H04B10/02
Filed: 2002-02-08
Abstract: The specification describes an optical transmission system for high speed, high capacity digital pulse transmission, i.e. at least 10 Gb/s at a duty cycle of at least 10%, which uses transmission fiber with a dispersion value greater than 20 ps/(nm-km) or more negative than -5 ps/(nm-km). The system operates in the pseudo-linear transmission mode (PLTM). In the PLTM it was discovered that pulse distortion decreases, i.e. eye closure penalty actually decreases, as the dispersion value increases. System performance actually improves by increasing the value of absolute dispersion of the transmission fiber.

In an alternative embodiment, flaps (31) may be juxtaposed with the closure system. The flaps encounter a change of position upon closure of the bag. The change in position may either be complete severance from the bag, or inflect from a first position to a second position upon closure or opening of the bag. Closure and/or opening of the bag may be accomplished by a slider (50).
