Title: Electronic method and circuit for analysing analog signals; coin testing
Inventor: ECHAPARE IBARROLA JESUS
IPC: H03M1/34
Filed: 1991-01-09
Abstract: The method comprises establishing, in an analog signal 5A, different measurement areas TA, TB, TC, based upon the said signal's gradient changes, to establish a digital signal SD according to such changes. An electronic circuit is used comprising an operational amplifier (1), with a time delay (2) that compares the analog signal SA with the same signal, insignificantly delayed with regard to the signal duration. When measuring a property of a coin the circuit may include two pairs of photodiodes - phototransistors (8 - 8') for detecting the coin diameter in addition to an electromagnetic sensor 4 connected via an oscillator (5) with the amplifier. A microprocessor 3 measures the duration aid frequency ratios between each of the areas TA, TB, TC and adjacent areas. The oscillator (5) sends a signal straight to the microprocessor (3) and another through the basic circuit. <IMAGE>

IPC: E02B15/06
Filed: 1991-10-01
Abstract: A method of containing oil or like spillage floating on the surface of the sea or other waterway is by means of a disposable self inflating boom assembly which is launched into the sea. Inflation of the assembly via control valves and supply lines is from a gas supply module, and both are launched from within a mobile assembly or container on a ship, platform, helicopter or by parachute from an aeroplane. Gas may be supplied from compressed gas cylinders, or by chemical reaction on contact with water, or from an air compressor or blower. Various arrangements of boom are described including having a membrane to create separately inflatable compartments, having at least one lower skirt, and using two adjacent boom assemblies. When the containment operation is completed the boom is recovered from the sea, cleaned and disposed of.

Patent GB-2266943-A (GB)
Title: Fail-safe valve actuator
Inventor: AKKERMAN NEIL HOOVER
IPC: F16K31/04
Filed: 1993-05-24
Abstract: A valve actuator has an electric motor 50 driving a nut 20 on a valve stem 18, via gear train 58-66 and a combined centrifugal clutch and torque-limiting device 56, to move the valve and compress spring 28. When a disc 36 on valve stem 18 abuts stationary shims 42, the torque limiting device disconnects motor shaft 54 from a drive shaft 57. The valve is held open against the closing force of the spring by a one-way clutch 100, which is locked by a pin (110, Fig 6) held in a groove (104) by a solenoid 106 against the action of a further spring. When power fails, the solenoid releases the pin and the valve returns to its fail-safe condition under the action of spring 26. The return motion of the valve and gear train is damped by means of a centrifugal brake (116, 118, Fig 6, 300, 302, Fig 14). The centrifugal clutch prevents the 36 torque limiter from operating under the high torque associated with starting of the motor. <IMAGE>
