Title: Multi-ply facial tissue paper product comprising biodegradable chemical softening compositions and binder materials
Inventor: OSTENDORF WARD WILLIAM
IPC: A47K10/16
Filed: 1994-10-17
Abstract: Multi-ply facial tissue paper products comprising biodegradable chemical softener compositions and a combination of a wet strength binder, either permanent or temporary, and a dry strength binder is disclosed. The multi-ply facial tissue paper products contain a biodegradable chemical softening composition comprising a mixture of biodegradable quaternary ammonium compound and a polyhydroxy compound. Preferred biodegradable quaternary ammonium compounds include diester dialkyl dimethyl ammonium salts such as diester di(touch hardened)tallow dimethyl ammonium chloride and/or diester di(touch hardened)tallow dimethyl ammonium methyl sulfate. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, polyglycerols having a weight-average molecular weight of from about 150 to about 800, polyoxyethylene glycols and polyoxypropylene glycols having a weight average molecular weight from about 200 to 1000. The multi-ply facial tissue paper products also contain an effective amount of a wet strength binder, either permanent or temporary, and a dry strength binder to control linting and/or to offset the loss in tensile strength, if any, resulting from the use of the biodegradable chemical softening compositions. The use of both wet strength binder, either permanent or temporary, and dry strength binder also improves the retention of the chemical softening composition in the sheet. This results in improving one or more of the following properties of the multi-ply facial tissue paper product the flexibility, the slip-stick coefficient of friction, the FFE-Index and the HTR-Texture. Preferably, the majority of the biodegradable chemical softening compositions will be disposed on the outer layers of the multi-ply facial tissue paper products where they are most effective. In other words, the biodegradable chemical softening compositions and the wet strength binder, either permanent or temporary, and the dry strength binder can be selectively distributed within the multi-ply facial tissue paper product to enhance the softness, absorbency, and/or lint resistance of a particular layer or ply.

Patent CA-2186253-A1 (CA)
Title: Combined feed and mixing device
Inventor: HUETTENHOFER KLAUS
IPC: B01F23/10
Filed: 1995-03-13
Abstract: In the flue-gas duct of a power station, it is customary to feed the ammonia necessary for the catalytic decomposition of oxides of nitrogen into the flue gases through a multiplicity of feed pipes and nozzles, and through the same number of valves to be adjusted, so that the ammonia is homogeneously distributed throughout the flue gases. The pressure drop produced by equipment of this kind in the flue-gas duct is relatively high, however, and the equipment itself is relatively complex and costly. In order to overcome these disadvantages, the invention proposes a combined feed and mixing installation (14, 36) designed to feed a first fluid medium (M1), e.g. ammonia, into a second fluid medium (M2), e.g. flue gases (28) containing oxides of nitrogen, conveyed by a duct (4) and to mix the two fluid media (M1, M2). The installation includes at least one pipe conveying the first fluid medium (M1), with at least one feed port (22), and a mixing unit (26, 26a to 26h). Relative to the cross-sectional area A and the hydraulic diameter ddydr. of the duct (4), the installation has 0.05 to 10 feed ports (22) per square metre of the cross-sectional area A. The distance a between each feed port (22) and the mixing unit (26, 26a to 26h) is between 0.05 and 3 times dhydr.. This ensures that the ammonia is fed in and mixed with the flue gases homogeneously (Fig.  2).

Title: Preserving state in stateless network protocols
Inventor: IYENGAR ARUN K
IPC: H04L29/06
Filed: 1997-06-02
Abstract: A method and system for preserving state in computers communicating over networks, such as the World Wide Web (WWW) using stateless protocols, e.g., HTTP. State is preserved in a conversation between a client requesting services from a served by performing the service and identifying all continuations (hyperlinks) in an output from the service; recursively embedding the state information in all identified continuations in the output sent to the client. The state information may be embedded and communicated by the server to the client. Alternatively, dynamically downloadable program code may be used to embed the the state information at the client. Additional features enable the filtering and/or addition of hyperlinks and data output from the services according to predetermined criteria. State information may be embedded by modifying an identified continuation which is a request for an HTML file, to invoke a CGI converter program with the identified continuation and the state information passed as arguments. State information may also be embedded by modifying an identified continuation which is an invocation to a CGI program with the identified continuation and the state information passed as arguments, and the embedding step is performed by the CGI program. Alternatively, an identified continuation which is an invocation of a CGI program may be modified to invoke a CGI converter program with the identified continuation, an argument counter which indicates a number of arguments associated with the CGI program, and the state information passed as arguments. Here, the embedding is performed by the converter program.

Title: Method and system for using mirrored data to detect corrupt data
Inventor: POPE DAVID E
IPC: G06F12/16
Filed: 1996-06-05
Abstract: Errors in data stored in the memory of a computer are detected prior to use of the data. A protected data type is declared in writing a program in which errors in critical must be detected before the data are used. The invention is preferably implemented on a personal computer system (10) or in a microcontroller for a device. When a protected data item is initialized, both the protected data item and its corresponding bit-inverted form are stored in memory. A constructor function is used to determine the bit-inverted form. Any time that the protected data item is subsequently accessed for use by an application program, either the stored protected data item or its corresponding bit-inverted form are inverted for comparison to the other stored data item. Any difference detected in this comparison indicates that a change has occured in either or both of the protected data item and its corresponding bit-inverted form within memory. Depending upon the application progam in which the invention is used, an appropriate action is taken upon detecting such an error, such as providing an indication of the error and terminating further execution of the program.
