Abstract: A valve may include: a valve body; a valve member in the body, movable between closed and open, comprising a first orifice, a second orifice, a main conduit between them, and a bypass in fluid communication with the main conduit. The bypass includes a first portion with a first cross-section area and a second portion with a second cross-section area different from the first cross-section area. The valve body comprises a compensation chamber having a compensation orifice. The bypass comprises an outer bypass orifice defined by and disposed on the outer surface of the valve member. The valve member comprises an internal orifice situated between the bypass and the main conduit. In the closed position, the inlet is in fluid communication with the compensation chamber via the outer bypass orifice, the bypass, the internal orifice of the valve member, the main conduit, the first orifice, and the compensation orifice.

Abstract: Method and apparatus for supplying the receivers with information in successive steps. The source supplies the first receiver with the information in a first step and supplies a second receiver in a second step whilst the first receiver simultaneously supplies the information to a third receiver. In further steps the source and already supplied receivers each supply a further receiver with the information until all receivers to be supplied have received the information. ADVANTAGE—Enables transfer of large quantities of program code and data from central station to several interconnected decentral stations, in very short time and with optimal use of transmission capacity.
