Title: Digital audio communications system
Inventor: RICHARDSON CHRISTOPHER KEITH
IPC: H04B1/66
Filed: 1987-03-21
Abstract: A communication system having a coder and a decoder of audio analogue and digital signals is disclosed. The coder employing a limiter 55 and sampling flip-flop device governed by a timing clock, this clock also providing a tone frequency for embedding in the input audio analogue signals 49. The decoder employs two multiplier devices, A, B both multiplier devices having incident digital data signals and one of the devices B also having a signal which is the inversion of the tone signal of the coder. The output of this multiplier device B being incident upon the other A to provide the resultant output analogue signal. In the example of the coder shown (Fig 4), amplitude envelope information is derived from a full wave rectifier 41 and a LPF 43. The amplitude envelope information carried by the data is extracted from a local decoder including a multiplier C and a LPF 51. These two envelopes are compared at a comparator 53 and the error signal is passed through a multiplier D to control the level of the tone fed to the limiter 55. <IMAGE>

Title: Determination of magnetic interference in a borehole
Inventor: MORGAN DAVID
IPC: E21B47/022
Filed: 1990-03-03
Abstract: To determine the magnetic interference within a non-magnetic drill collar 12 disposed in a drill string within a borehole due to the presence of magnetised sections of the drill string above and below the drill collar 12, two magnetic detectors 22 and 23 are spaced apart along the axis of the drill collar 12. Magnetic measurements of component of the magnetic field along the axis of the drill collar are then taken with the detectors 22 and 23, while the drill collar 12 is maintained at a common measurement location within the borehole. The magnetic interference due to the magnetised sections of the drill string above and below the drill collar 12 is then calculated from inter alia the measurements taken by the detectors 22 and 23 at the measurement location. Magnetic measurements of magnetic field components perpendicular to the axis and measurements of gravity may also be made. Both detectors are preferably fluxgate magnetometers and are located between the midpoint M and one end PL of the drill collar. <IMAGE>

Title: Method and apparatus for controlling flow of molten metals
Inventor: MONKS JAMES HERBERT
IPC: B22D41/14
Filed: 1990-12-20
Abstract: The invention provides for controlling the flow of molten metal from a holding vessel such as a tundish through a discharge orifice (2) into a receptacle such as a mould. Within the holding vessel is provided a flow control chamber (1) comprising a down-flow chamber (6) having an outlet at its lower end leading to or forming part of the discharge orifice (2), and an opening at its upper end. Also provided is an up-flow chamber (4) having a lower inlet (5) for melt from the holding vessel, and an opening at its upper end. The upper end openings coincide and are provided by a weir-forming partition member (3). An upper chamber (7) can receive gas at a pressure to allow molten metal from the holding vessel to pass through the inlet (5) to establish in the lower end of the down-flow chamber (6) a column of molten metal with a volume of gas occupying the upper end of the flow control chamber and serving to separate the column of molten metal from the up-flow chamber (4), whereby an equilibrium is established between molten metal passing through the inlet (5) and molten metal passing out through the discharge orifice (2) such that the height of the column of molten metal in the down-flow chamber (6) remains substantially constant. By increasing the gas pressure, and hence reducing the said volume of gas, the height of the column of molten metal increases and thus also the flow rate through the discharge orifice; or by reducing the gas pressure, and hence increasing the said volume of gas, the height of the said column decreases and thus also the said flow rate. In an alternative embodiment (Figure 2, not shown) the gas system operates by creating a variable low pressure (suction) in the upper chamber. <IMAGE>
