Title: Electromotive force suppression system
Inventor: NIIRO YASUHIKO
IPC: G02B6/44
Filed: 1988-08-18
Abstract: Electromotive force induced in an optical fiber cable (1) which has no outer conductor is suppressed by providing means for increasing capacitance between the cable and the ground, and/or decreasing inductance of the cable itself. The capacitance increasing means (6; 8) is a conductor contacting with both outer surface of the cable and the ground. The inductance reducing means is a conductive means (9, Fig. 4; 9, 10, Fig. 6; 9a, 9b, Fig. 7) which consumes power generated by the electromotive force in the cable, a magnetic body (11, Fig. 8; 12, Fig. 12) which concentrates magnetic flux or separates magnetically layers of the cable, or winding direction of the cable so that the coil is wound in opposite direction alternately in every predetermined cable length. <IMAGE>

Title: Buffer synchronisation in a variable transmission rate codec
Inventor: WELLS NICHOLAS DOMINIC
IPC: H04N7/24
Filed: 1991-01-16
Abstract: In order to synchronise buffer delays between coder and decoder buffers in a transmission system, e.g. an HDTV system, a signal representing the coder buffer occupancy Bc(r) is transmitted to the decoder with the picture signal. The transmission rate R or changes DELTA R in the transmission rate is summed or integrated at the cooler up to a point in time t1 at which picture information is written into the cooler buffer and a signal representing the resulting sum or integral is transmitted to the decoder with the picture signal. The decoder buffer occupancy Bd(r) is adjusted in response to the signals transmitted with the picture signal to adjust the delay through the decoder buffer and synchronise it with the delay through the cooler buffer. Underflow or overflow at the decoder buffer is also avoided.

Title: Multi stage flash evaporator
Inventor: ELMORE CARL L
IPC: B01D3/06
Filed: 1991-08-13
Abstract: A multi-stage flash evaporator is constructed so that the evaporator elements (23) are dimpled plates mounted so that they extend horizontally. One, two, or more sets of plates may be mounted in each evaporator stage, the sets stacked upon one another in a tier arrangement. Each stage may be formed by a circular cross-section vessel (17), with I-beams extending horizontally at about the horizontal diameter of the vessel, and supporting the dimpled plates. A condensate collection trough (28) is mounted below the dimpled plates and at the I-beams, the I-beams having openings in them through which condensate collected by the trough passes from one end of the vessel to the other. The hot liquid - such as sea water to be desalinated - to be evaporated is passed into a bottom chamber (24) of each stage vessel, with vapor flowing upwardly through demistors (27) and channels, into contact with the dimpled plates, and the condensate falling as a thin film down the plates and collecting in the condensate trough. The brine is preheated by passing it into the passageways within the dimpled plates counter to the direction of flow of the brine into and through the bottom chambers. The plates are preferably titanium or aluminum, but may be stainless steel if brackish water is distilled. A sacrificial anode may be mounted adjacent the plates. <IMAGE>
