Title: Startup procedure for international line powered daa
Inventor: LATURELL DONALD RAYMOND
IPC: H04M19/08
Filed: 2000-10-04
Granted: 2005-04-19
Abstract: A line powered data access arrangement (DAA) is disclosed which adaptively allows proper operation with power supplied from a telephone line as conditions warrant, while at the same time satisfying the relevant requirements of many countries. In the line powered codec, a startup procedure for the international line powered codec uses register settings, e.g., country-specific register settings, which are powered and maintained from the low voltage side (e.g., from the PC or modem side) of the line powered codec. In this way, even during low line power conditions the programmed state of the line powered codec can be maintained, thus a default condition will not necessarily returned to by the line powered codec upon reset due to a power loss in the telephone line. In another aspect, a charge storage device such as a charge capacitor is charged from a charge pump formed from a differential clock signal from the low voltage side. A current and voltage detection module in the line powered codec is always powered from the telephone line. Upon detection of an off-hook signal or a power down condition, the current detection module determines if/when the current and voltage on the telephone line is sufficient to power certain circuits on the line powered codec. If sufficient power is not present, the line powered codec does not power up. However, the line powered codec will power up if sufficient current is detected. In another aspect, a plurality of power rails may be provided. A first power rail may be associated with the line power, a second power rail may be associated with a low voltage side power source, e.g., a charge storage device. A third (and other) power rails may be switchably connected to either the first power rail or second power rail as line power conditions and on-hook/off-hook conditions warrant.

Title: Alkenyl succinic anhydride size emulsification with a natural gum for paper products
Inventor: DOSTIE DANIEL R
IPC: C09K23/56
Filed: 1999-04-06
Granted: 2008-01-29
Abstract: A natural gum is used to provide improved emulsification of alkenyl succinic anhydride (ASA) sizing agents for paper products.  The natural gum can be nonionic, cationic, anionic, amphoteric, oxidized, derivatized, or modified. The preferred natural gum is from the family of galactomannan gums in which guar gum is a primary example. The alkenyl succinic anhydride (ASA) size emulsion formed with the natural gum improves stability and the film formed is evenly distributed, thereby promoting more uniform sizing of the paper product.  The ratio of the ASA to natural gum in the emulsion ranges from 0.01:1 to 100:1, and preferably 0.1:1 to 20:1. The amount of ASA size is 1 lb./ton to 10 lbs./ton of finished paper product and preferably 2 lbs./ton to 8 lbs./ton. A surfactant may be used to further improve the stability of the emulsion.

Abstract: A gauge for a coordinate measuring machine has a plurality of balls whose centers are located on at least one line inclined with respect to a reference axis in a virtual reference plane. The gauge is set on a measuring table of the coordinate measuring machine. Orthogonal coordinates in which one of the coordinate axes is identical to the reference axis are set in the virtual reference plane. The coordinates of the center of each ball are measured by the coordinate measuring machine.  Thereafter, the gauge is turned and inverted by 180 degrees about the reference axis and is set again on the measuring table. Orthogonal coordinates in which one of the coordinate axes is identical to the reference axis are set in the virtual reference plane.  The coordinates of the center of each ball are measured in the same way as above.  Thus, measurement errors of the straightness of the machine ares of the coordinate measuring machine and the orthogonality between the machine axes can be easily and precisely evaluated.

Abstract: This invention provides integrated knuckle drive link conveyor belt systems with improved long wear-high load bearing link coupling joints of a universal joint nature for permitting the belts to travel on straight or curvaceous paths which also feature expedited insertion of spindle rods extending through the knuckles, diverse sprocket drive capabilities and replaceable load conveying platform accessories of the plug-in or snap-in variety. A cylindrical knuckle, when the loaded belt is under tension, has a substantially semi-cylindrical high wear contact surface that handles heavy peak loads. That knuckle is installed expeditiously at a joint between end-to-end connected links consisting a special interfitted jig comprising a seat in the nose end of a link resting the knuckle in a registered operational position to receive the connecting spindle rod through trailing edge bifurcated arms of a leading modular link without a concurrent manual orientation of the knuckle. Diverse sprocket drive structure permits the belt to be driven from beneath or on either lateral side. The knuckle and surrounding seat provides three dimensional moving tolerances to provide the universal joint type operation at each link joint. Other features include side rollers to reduce friction on inner curve radii, and holddown flanges that keep the bel t from fluttering off a base support surface. The rugged molded resulting plastic links are long wearing and resist catastrophic failure. The versatility and ruggedness of the system is significantly enhanced by the removable platform structure for heavy industrial use.</SDOA B>
