Abstract: A composition for saturation of preformed, previously cured foam substrates having an at least partially open cell configuration, includes a polymer binder in which microspheres containing a phase change material are dispersed. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. A  preferred cured foam substrate is a skived polyurethane or polyether foam of from 20 to 1,000 mils in thickness, preferably 20 to 200 mils in thickness, having up to 6 ounces per square yard or more of encapsulated phase change material embedded in a polymer binder. One method of applying the binder with dispersed encapsulated phase change materials is by applying a binder/microsphere dispersion to the upper surface of a previously cured foam sheet, then drawing a vacuum from the underside of the cured foam sheet to permeate from 20 % to 100 % of the cured foam sheet with the binder/microsphere dispersion. The resulting product is then cured. An alternative method of applying the binder with embedded encapsulated phase change materials using knife over roll technique to an exposed surface of the skived foam is disclosed in which the most preferred viscosity of the uncured polymer binder is from 7,000 to 9,000 centipoise.

Abstract: A system and method for preventing time-walking in a digital switching network when switching from a first clock to a second clock. The first and second clock can be identical in frequency and independent in phase, where the highest resolution frequency available is that of said first and second clock. The system can include a clock divider selection circuit, an enhanced digital phase aligner, and a clock select control circuit. The clock divider selection circuit can output an on-line divided clock and an off-line clock to the enhanced digital phase aligner. The enhanced digital phase aligner can sample the on-line divided clock with four phases of the off-line clock and output an off-line divided clock which is time shifted such that the off-line divided clock is in phase with the on-line divided clock within plus or minus one-half the clock period of the off-line clock.      The clock select control circuit can receive the on-line divided clock from the clock divider selection circuit, the off-line divided clock from the enhanced digital phase aligner and a smoothed clock. When a request is made to switch between clock one and clock two, the clock select control circuit can evaluate the on-line divided clock and the off-line divided clock with the smoothed clock and output a clock select control signal to the clock divider selection circuit based on this comparison.

Abstract: An apparatus and method primarily intended for repairing pipes and conduits, particularly high-pressure pipes and conduits, such as a watermain (21). To prevent the creation of a gap between a repair sleeve (20) and the inside of a host pipe (21), when an epoxy or other curable sealant is used, due to the slight rebound that occurs during the locking of the edges of the sleeve, a bubble gasket (29) or a quantity of loose bubbles is used. During such rebound and locking of the edges of the repair sleeve, the bubbles maintain a force against the sealant as the sealant cures. Although conduit repair is an intended specific application of the invention, the apparatus and method of the invention has broader applicability and are contemplated to encompass the securing of a curable sealant to a surface and the general bonding of two surfaces together.

Title: Method, computer program product, and system for distributing changes made in a data store to remote client copies of the data store
Inventor: DEVINE JOHNATHAN
IPC: G06F17/30
Filed: 1998-05-26
Abstract: A method, computer program product, and system that allows changes made to an original database table found on a server computer to be reflected in client copies of the database table based on intermittent client requests for synchronization. A server makes periodic updates of table differences between current table (20) receiving database change events and reference table (28). Each client copy of a database table and update (created by the server has a sequential version number associated therewith). The server will compare the version number of a client copy of a database table with the most recent version number of the table on the server to determine which updates need be applied in order to make the client copy current. Next, the updates will be translated from a generic format into instructions that are specific to the type of database engine being run on the client. Finally, the instructions are transmitted to the client (along with the new version number) so that the client may operate the database engine to apply the instructions for making the database table current with the original managed on the server.
