Title: A method for combined use of a local rtk system and a regional, wide-area, or global carrier-phase positioning system
Inventor: SHARPE RICHARD T
IPC: G01S19/43
Filed: 2004-12-15
Abstract: The present invention includes a method for a combined use of a local RTK  system and a regional, wide-area, or global differential carrier-phase positioning system (WADGPS) in which disadvantages associated with the RTK and the WADGPS navigation techniques when used separately are avoided. The method includes using a known position of a user receiver that has been stationary or using an RTK system to initialize the floating ambiguity values in the WADGPS  system when the user receiver is moving. Thereafter, the refraction~ corrected carrier-phase measurements obtained at the user GPS receiver are adjusted by including the corresponding initial floating ambiguity values and the floating ambiguity values are treated as well known (small variance) in subsequent processes to position the user receiver in the WADGPS system.

Abstract: The laminate useful as the shaped nappies or the devices for the incontinence of the adults and babies, comprises two non-woven layers (301, 401), and left and right elastic films (201, 202) engaged between the two non-woven layers by interposition of an adhesive. The laminate has an activated width lower or equal to the cross section width. The activated width has a left side and a right side. The elasticity increases over the left edge on a part of left side of the activated width and decreases on a part of the right side. The laminate useful as the shaped nappies or the devices for the incontinence of the adults and babies, comprises two non-woven layers (301, 401), and left and right elastic films (201, 202) engaged between the two non-woven layers by interposition of an adhesive. The laminate has an activated width lower or equal to the cross section width. The activated width has a left side and a right side. The elasticity increases over the left edge on a part of left side of the activated width and decreases on a part of the right side towards the straight edge of the activated width. The elasticity curve of the laminate is measured by a test of stretching to 10 Newton (in percentage of lengthening) in function of the distance in mm of the point of measure at the left edge of the activated width presented in each point of measure of the increasing part, or left side. A slope of the elasticity curve is lower than 15%/mm, and comprises between 15 and 5. The two elastic films have a left and a right activated length. The elasticity curve of the right activated length is symmetric as in a mirror of the elasticity curve of the left activated length. The slope in absolute value of the curve in the right part of decrease of the left activated width is lower than 7 of the left part of increase of the left activated width. The curve presents a maximum for a point of measurement at middle of the activated width of the laminate. Independent claims are included for: (1) a process of assigning elasticity with a laminate; and (2) a device for assigning elasticity with a laminate.

Title: Power lever chain motor
Inventor: WOODS JOHN T
IPC: F03G7/10
Filed: 2007-04-04
Abstract: Many previous efforts to construct a perpetual motion machine (weight motor), and have all met with failure. Indeed physicists and mechanical engineers have insisted that it is an impossible task. This machine utilizes wheels (mainly sprockets) and chains, and a leveraging system, to achieve the desired effect.   In the most efficient model of the following motor, five shafts are utilized:  a central god shaft, which carries two very large single outer sprockets each of which carries double strand chain with the second strand reaching inward to present an engagement site for smaller sprockets (or internal gears); two angel shafts-each diametrically opposed to the other-whose outer sprockets engage the free strand of god chain (or pinion gears); and two tug shafts which are farthest from the god shaft and adjacent to each angel shaft. The god shaft and the angel shafts are held to a constant 'equatorial' position parallel to one another, while the tug shafts are allowed to teeter slightly about the god shaft via teeter arms. Clearance slots are cut into the teeter arms on each side the god shaft to allow them slight movement free of the angel shafts.  The god shaft also supports an inner sprocket whose connecting, reciprocating chain engages a small inner sprocket on each of the tug shafts. There are also two medium sized inner sprockets on each of the angel shafts, which reach beyond the distance described by the short tug shafts.  The single-strand inner angel sprockets also carry double stranded chain whose free second strand reaches inwardly, each to allow a small sprocket residing at each end of the tug shaft to engage it.   The ratios of outer angel sprocket (or gear) to god sprocket (or gear); of inner god sprockets to inner tug sprockets; of outer tug sprockets to inner angel sprockets; are such that all shafts spin in harmony.   Because the tug wheels must always describe a perfect arc about the god shaft axis, but the curve of the receiving inner angel sprocket cannot duplicate that perfect arc, the angel wheels are forced to rotate to accommodate the engaging tug wheels. Thus, when the teeter arms are moved either up or down, so also the angel wheels, and the god wheel must move in the same direction.  The produced feedback loop causes the spin to be perpetuated so long as pressure is exerted against the teeter arms at either end of them.   This motor can operate in any attitude, and in virtually any medium. Neither fuel nor even gravity is required.
