Abstract: A system for enhancing group communication includes a computer server for receiving a first digital from a remote client. The server analyzes the first image to determine one or more first image attributes and communicates the image to one or more recipients. Communication information including image attributes, email addresses, and names of the recipients is stored. When a second image is received the server analyzes it to determine its attributes and forms second image communication information relevant to the second image. The second communication information includes data from the first image communication information, its image attributes, and one or more separate second image recipients.

Abstract: A server analyzes a received digital image to determine and store one or more first image attributes. The image is transmitted to at least one recipient and pertinent information is recorded, including one or more image attributes and the one or more first image recipients. A second image is received and analyzed in a similar fashion as the first. Second image communication information is generated that is relevant to the second image based on a comparison with the first image communication information and the one or more first image attributes.

Abstract: A quick-lock-and-quick-release system, using predetermined clamping and releasing methods to be assembled, disassembled, and adjusted for supporting and protecting a recreational-vehicle sewer hose, comprises a first semi-circular sequential-locking end joint, a second semi-circular sequential-locking end joint, semi-circular sequential-locking middle joints, quick-lock-and-quick-release stake-clamping jaw screws, quick-lock-and-quick-release jaw-squeezing chamber nuts, square-cross-section multi-purpose two-way stakes, and semi-circular sequential-locking pipes. The quick-lock-and-quick-release system eliminates permanent frictional forces between the multi-purpose two-way stakes and quick-lock-and-quick-release jaw-squeezing chamber nuts: a) To allow quick and easy assembly of the system, b) To allow quick and easy disassembly of the system, c) To allow the two-way stakes to be used right side up or upside down, and d) To eliminate personal injuries caused by the two-way stakes when they become rusted.

Abstract: A mixing valve which provides water of a constant temperature when connected to sources of hot and cold water. The valve comprises a cylindrical housing having first and second axially aligned spaced inlet connectors, a rotatable pressure selection element positioned within the housing, an axially translatable pressure equalizing element positioned within the pressure selection element and a rotatable temperature selection element positioned within the pressure equalizing element. The pressure selection element has first and second ports substantially aligned with the inlet connectors to the housing. The pressure equalizing element has inner and outer concentric radially spaced coaxial cylinders and a centrally located spacer interposed between the cylinders.

Abstract: A mixing valve which provides water of a constant temperature when connected to sources of hot and cold water. The valve comprises a cylindrical housing having first and second axially aligned spaced inlet connectors, a rotatable pressure selection element positioned within the housing, an axially translatable presure equalizing element positioned within the pressure selection element and a rotatable temperature selection element positioned within the pressure equalizing element. The pressure selection element has first and second ports substantially aligned with the inlet connectors to the housing, the pressure equalizing element has first and second ports axially aligned and angularly displaced from the first and second ports in the pressure selector and the temperature selection element has first and second ports angularly displaced with respect to each other and to the first and second ports in the pressure equalizing element.

Abstract: Compounds of formula ##STR1## in which X is a phenyl or alkyl phenyl group, A is a phenyl, alkyl phenyl or phenyl alkyl group or a group of formula YCOOZ in which Y is a phenylene or (CH.sub.2).sub.m group and Z is a group of formula ##STR2## or an alkyl group, X' is a phenyl or alkyl phenyl group, m, n and p are integers and each of R and R' represents either a hydrogen atom or methyl group, are useful as plasticizers for P.V.C.
