Abstract: A modular valve is provided. The modular valve includes a valve body having a pair of inlet ports and a pair of outlet ports. The pair of inlet ports each includes an integral stop valve and check valve. The valve body includes a cavity configured to selectively receive a pressure balancing cartridge or a thermostatic cartridge assembly.

Abstract: To supply messages to an audience of Internet users, the messages are initially stored on an Internet server which is accessible by a group of Internet clients operated by Internet users, when a message is received at the server, it includes an information part and a data part. The data part includes at least one identifier specifying the intended audience of the message. In the server, the information part of the message is stored as an HTML file in a first store and the URL of the file containing the information part of the message together with the identifier or identifiers of the intended audience are stored in a second store. To view messages intended for a particular user on one of the clients, the client transmits requests automatically at periodic intervals to the server for new messages intended for the user. In response to each request, the server scans the fields in the second store to compile a list of URLs of messages intended for the user.

Abstract: A balancing valve has a housing formed with a pair of inlet ports and a pair of coaxial tubes having outer ends seated in the housing at the ports and opposite confronting and axially closed inner ends. The tubes are each formed with a radially throughgoing aperture and a flexible membrane has a center sealingly engaged between and fixed to the inner ends and an outer periphery seated in the housing and defines a respective compartment around each of the tubes. A pair of like sleeves coaxially surrounding the tubes each have an inner end fixed to the membrane offset from the center and from the outer periphery and an outer end. Formations on the outer ends of the sleeves and on the tubes form annular valve openings of flow cross sections dependent on an axial position of the sleeves relative to the tubes.
