Title: Stable paving compositions having improved low and high temperature properties
Inventor: YOUSEFI ALI AKBAR
IPC: C08K9/08
Filed: 2000-07-14
Abstract: A paving composition comprises a mixture of about 90 to 99.5 wt.% of an asphaltic material and about 0.5 to 10 wt.% of solid particles each encapsulated with a cross-linked polymer, the encapsulated particles being uniformly dispersed in the asphaltic material. The encapsulated particles have a particle-to-polymer weight ratio so as to provide a density match between the encapsulated particles and the asphaltic material. The paving composition according to the invention has a higher complex viscosity at high temperatures (60°C) and is more ductile at low temperatures (-15°C) in comparison with the base asphaltic material. Moreover, the composition is completely stable at elevated temperatures (160°C) or during long periods of storage.

Abstract: The invention relates to a device for fixing a wheel-alignment gauge to a rim of a wheel of a motor vehicle. According to the invention, a base part has means for fixing the wheel-alignment gauge in a predefined reference direction in relation to the base part. Three supporting arms are arranged on the base body which extend substantially radially in a plane which is perpendicular to the reference direction. Spacing elements are positioned on the supporting arms such that they can be displaced longitudinally in relation to same. The ends of the spacing elements, which serve to ensure a three-point mounting on a wheel rim, lie in a plane which is perpendicular to the reference direction.  The invention also provides for means for fixing the base part on the rim. At least one of the spacing elements (24, 54) can be adjusted cross-wise to its supporting arm. In this way it is possible to adjust the position of the spacing elements to different divisions of the wheel mounting nuts.

Patent CA-2329737-A1 (CA)
Inventor: ANDERSSON HANS
IPC: H04W24/04
Filed: 1999-03-26
Abstract: A method and system are disclosed for more effectively restoring cells in a radio communications network, whereby the current traffic conditions are taken into account. The disclosed method (100, 300) can be implemented in a number of ways. For example, if a network operator desires to prioritize recovery on a cell-by-cell basis, the order of prioritization can be overlaid on the present method (e.g., for all "priority 1" cells, the present method will be used to select a cell recovery order). Alternatively, the present method can be overlaid on an operator's order of prioritization (e.g., for all cells that are classified most urgent according to the present method, the operator's priorities will be used to select the cell recovery order). As another example, if a hierarchical cell structure is in use, the underlaid cells can be selected for recovery during the initial recovery operation (e.g., for a speedier recovery). Also, a recovery order sequence can be used to select certain cells from within the group of underlaid cells. As such, the radio network's recovery is optimized by taking into account the actual traffic requirements in the network, or in the node and/or cells involved.

Abstract: A synchronization establishing apparatus in a spectrum spread communication system includes a search section (100, 200, 7, 10), a frequency offset estimating section (11) and a demodulation path selecting section (12). The search section (100, 200, 7, 10) calculates correlation values from a received spectrum spread signal, and calculates power values as addition values of symbols corresponding to the correlation values and power addition values of the power values. Also, the search section selects larger ones of the power addition values to output together with timing data corresponding to the selected larger power addition values. At this time, one of the symbols and the power values being corrected in phase based on frequency offsets. The frequency offset estimating section (11) estimates the frequency offsets from one of the correlation values and the power values and demodulation timing data to output to the search section. The demodulation path selecting section (12) selects path timings from the timing data used on the selected larger power addition values and outputs the demodulation timing data indicative of the bath timings to the frequency offset estimating section.

Title: A lubricating method for silicate drilling fluids
Inventor: BASS JONATHAN L
IPC: C09K8/22
Filed: 1999-06-25
Abstract: Improved silicate drilling fluids are produced by the addition of tetra alkyl ammonium compounds, in particular tetra methyl ammonium hydroxide to silicate drilling fluid mud to lower the co-efficient of friction between drill string and wellbore. It has also been discovered that the same tetra alkyl ammonium lubricant compounds greatly lessen the viscosity breakdown of swelled hectorite clay in the presence of silicate. This allows the preparation of silicate drilling fluids not only with enhanced lubricity but having stable rheology at the higher temperature and pressures encountered in some drilling operations.

Title: Coating compositions containing modified carbamate-functional polyacrylic binders
Inventor: ST AUBIN DONALD
IPC: B05D7/24
Filed: 1999-11-03
Abstract: The invention provides a process that includes a first step of reacting the hydroxyl groups of an acrylic resin having hydroxyl groups and carbamate groups with a compound that converts the hydroxyl groups to new groups unreactive with an aminoplast crosslinker; a second step of combining the acrylic resin reaction product with at least an aminoplast crosslinker to form a coating composition; and a third step of applying the coating composition to a substrate and curing the applied coating layer, in which substantially no ether linkages are formed. Aminoplast crosslinkers are desirable for other reasons such as providing high solids coatings having excellent appearance that cure under moderate conditions. Avoiding the ether linkages that could be formed by reaction of aminoplast crosslinkers with hydroxyl groups improves the resistance of the cured coating to environmental etch.
