Abstract: ? ABSTRACT CORIOLIS MASS FLOWMETERS In a coriolis mass flowmeter a flexible tube structure for carrying the fluid to be measured comprises parallel tubes (1,  2) fixed at (7,  8) and formed with loops (5, 6).  Electromagnetic means vibrate the loops in their own planes in directions normal to arms A, B of the tubes setting up torques on the loops sensed by two sensor pairs (14, 15).  The signals from the two sensors are used to measure the mass flow rate (since the later is proportional to the time phase-shift of these signals). Also the signals are used to drive and control the driving device for the electromagnetic means.

Granted: 1990-11-13
Abstract: ABSTRACT FAULT DIRECTION in an OPTICAL COMMUNICATIONS SYSTEM     An optical duplex system may continue to operate after a break in a fibre if light is reflected at the break and received back at the transmitting station, and that station is unable to identify the origin of the data.  To prevent this, in a simple 2-channel duplex system, data transmitted from one end is inverted prior to transmission and reinverted at the receiving end, while information from the other end is transmitted and received without inversion.  If there is a break, the stations at both ends will receive inverted data and the fault is quickly revealed.  In a 2x4 channel multiplex system, one channel from one end is inverted before transmission, whilst three channels from the opposite end are inverted before transmission.
