摘要:
The invention concerns a system for distributing fluid pressure to several fluidic motors from a common location. At the common location, a source pipe, which acts as the source of fluid pressure, travels past, and couples with, each pipe in a group of receiver pipes in sequence. Pressure in the source pipe is controlled so that the pressure is proper for each receiver pipe with which the source pipe couples. The receiver pipes connect with fluidic motors. Accordingly, a single control apparatus, located near the source pipe, is used and the pressure and flow from the source pipe is time-multiplexed and transmitted to the fluidic motors.

摘要:
A method to encode and to decode frames of data used in synchronous protocols, including HDLC and SDLC. The invention operates on blocks of data, such as data bytes or data words, in a parallel rather than a bit serial manner. The invention compares an aligned block of data with reference bit sequences for flag or abort signal detection, for zero detection, for zero deletion, for detection of consecutive one bits, and for zero insertion following a stream of consecutive one bits, for encoding and decoding according to various protocols. The invention also maintains proper data alignment following such zero insertions or deletions, and provides encoding and decoding under both data overrun and data underrun conditions.

The modem of this invention is capable of direct connection to a communication Host associated with a mainframe computer which uses a bisynchronous (bisync) protocol so that the Host believes a valid terminal is continuously connected regardless of whether the modem is online or offline. This permits communications to be established with the mainframe over the public switched telephone network.
