Title: Facsimile service
Inventor: GILLON ALEXANDER C
IPC: H04N1/21
Filed: 1990-02-08
Granted: 1993-10-14
Abstract: This invention relates to an arrangement for efficiently transmitting facsimile signals from a facsimile source to a facsimile destination using a standard facsimile user interface. The connected switched communications network recognizes that the call is from a facsimile source or to a facsimile destination and causes the facsimile signals to be transmitted at the transmission speed of the source to storage in a network. Subsequently, the signals are transmitted from storage to a facsimile destination at the transmission speed of the destination when the destination becomes available. Advantageously, the source need not wait for the destination to become available before transmitting, and the transmission can take place at a bit rate that matches the source and the destination even when these bit rates are different. Retransmission because of errors in one link is only required for that link, i.e., from the source to the storage or from the storage to the destination. Advantageously, this is accomplished without changing the very simple user interface of prior art facsimile transceivers.

Abstract: Buoyancy bases(1,1a) are filled with sea water. Upright buoyancy columns(2) are mounted on opposite sides of each base. Cylinder pairs(4) with inlets(5) on the bottom faces, are movably mounted on cross-members(3) connecting the columns. A hollow piston(6) is received in a corresponding cylinder. A buoyancy plate(9) with elongated opening at each corners receives support rod(12) connected to cross-member(11). The upper end of each piston is connected to a main water pipe(14) of a pressure control water collecting hose(15).
