Title: Paired warp triple layer forming fabrics with optimum sheet building characteristics
Inventor: QUIGLEY SCOTT
IPC: D21F1/00
Filed: 2005-08-01
Abstract: A papermaker's fabric, usable in the forming section of a paper machine, having two layers of cross-machine-direction (CD) yams. Interwoven with the CD  yams is a system of MD yams. At least some of the MD yams are grouped into alternating pairs comprising a crossing pair having a first MD yam and a second MD yarn and a second pair having a third MD yarn and a fourth MD yam.  The first MD yam and the second MD yam combine to weave each CD yam in the first layer and cross between the first layer and the second layer. The left and right warp yarns in the pairs are aligned in such a way that like adjacent yams from adjacent pairs have MD cell lengths greater than or less than the MD  cell lengths from non-like adjacent yams from adjacent pairs. The third MD yam is interwoven with the first layer of CD yarns and the fourth MD yam is interwoven with the second layer of CD yams. In this manner, a paired warped triple layer forming fabric may be produced which minimizes drainage and crossover point topographical markings.

Patent CA-2582365-A1 (CA)
Inventor: JONES FRANKLIN B
IPC: E21B7/04
Filed: 2005-10-18
Abstract: A method and control system for directional drilling are described. A drill string motor is commanded to rotate at a constant speed in a forward direction and the constant speed in a reverse direction for a first duration and a second duration, respectively, for at least one oscillation cycle. The difference between an averaged absolute angle of the drill string and a target rotation angle for the drill string is maintained near zero by adjusting the length of the durations as necessary. The target rotation angle can be changed based on measurement while drilling data obtained during drilling operations.  Advantageously, friction between the drill string and bore hole is reduced, leading to an increase in the drilling penetration rate.

Patent CA-2596482-A1 (CA)
Inventor: SCHUETTENBERG DONALD W
IPC: B60P3/07
Filed: 2007-08-08
Abstract: A front tow extended saddle is disclosed. The saddle allows a first towing truck to mount a second truck, facing forward, behind the first truck, in order to tow the second truck to a distant location. The saddle allows the towed truck to face forward during transport, thus allowing for the normal loads and stresses of movement on the towed truck. This configuration is preferable to movement with the towed truck facing-rearward, in which the typical aerodynamic surfaces of a large truck act as a drag during transport, imposing high wind loads and unusual stresses. The front tow extended saddle is also designed to minimize the required vertical rise on the towed truck, which also avoids additional stresses during loading and unloading onto the towing truck.

Abstract: An input signal such as a HDTV signal is split into a primary signal, which can be decoded if desired, and an secondary signal, which can remain compressed. The primary signal may be delayed and then both signals are transmitted to a receiver. If no error in the primary signal is detected, the primary signal is used to display data. Otherwise, the secondary signal, which arrives before the primary signal and consequently which is available for substitution, is displayed.

Abstract: An abnormally rapid ventricular cardiac rate that results from atrial fibrillation can be reduced by stimulating a vagal nerve of the heart. An apparatus for such stimulation includes a power transmitter that emits a radio frequency signal. A stimulator, implanted in a blood vessel adjacent the vagal nerve, has a pair of electrodes and an electrical circuit thereon. The electrical circuit receives the radio frequency signal and derives an electrical voltage from the energy of that signal. The electrical voltage is applied in the form of pulses to the pair of electrodes, thereby stimulating the vagal nerve. The pattern of that stimulating pulses can be varied in response to characteristics of the atrial fibrillation or the ventricular contractions.
