Patent EP-0452557-A1 (EP)
Inventor: NGUYEN QUANG-TAN
IPC: G01R19/00
Filed: 1990-12-18
Abstract: The circuit measures the level of an electrical signal, possibly with reference to a reference voltage. It can, with advantage, be applied to amplifiers with automatic gain control. 
<??>The circuit measures the level of an input electrical signal (Ve) and consists of an input amplifier (1), biased by a bias voltage, receiving this input signal (Ve) and producing an output signal (Vs), followed by a detector (2), itself followed by an integrator (3) delivering an integration signal (Vi). These three units form a measurement channel, the said integration signal (Vi) being the sum of a signal with a level proportional to the level of the said input signal (Ve) and an offset signal. The measuring circuit also incorporates a generator (6) producing a reference voltage (Vr), a compensation module (4) receiving the reference voltage (Vr) and producing a compensation signal (Vc), and a differential measuring amplifier (5) receiving the integration and compensation signals and producing a measurement signal (Vm). The bias voltage is the reference voltage (Vr). The compensation module (4) comprises stages corresponding to the units in the measurement channel in order to pass on the reference voltage (Vr) in conditions similar in all respects to those of the measurement channel. This produces a correction signal having the same value as the offset signal, the correction signal being included in the compensation signal (Vc).

Abstract: A workpiece transfer apparatus includes a first arm (30) mounted at its lower end on a base (20) for angular movement about a first angular movement axis (O1) extending substantially horizontally. A second arm (40) is mounted at its upper end on an upper end of the first arm for angular movement about a second angular movement axis (O2) parallel to the first angular movement axis. The first arm is longer than the second arm. The apparatus further comprises a holder device (50) for releaseably holding a workpiece (W). The holder device is mounted on a lower end of the second arm. The holder device and the first arm are disposed respectively on the opposite sides of the second arm spaced from each other in the direction of the first and second angular movement axes, so that the holder device, when moving horizontally, does not interfere with the first arm.

Abstract: Process for the continuous conversion of light olefin gas feed containing ethene, propene and butene to produce heavier hydrocarbons by contacting the light olefin feed in a fluidized bed reaction zone (5) with a medium pore molecular sieve zeolite catalyst under oligomerization conditions to convert the light olefin feed to heavier hydrocarbons. The catalytic reaction causes the conversion of the light olefins to heavier hydrocarbons, the deposition of coke by-product on the catalyst and the adsorption of hydrocarbon product on the catalyst. The deposited coke causes the partial deactivation of the catalyst. A portion of the partially deactivated catalyst containing deposited coke and adsorbed hydrocarbon product is continuously withdrawn from the reaction zone (5) and transferred to a catalyst stripping zone (13) in which the catalyst is contacted with an inert stripping gas to remove the adsorbed hydrocarbons from the catalyst. The stripped catalyst containing deposited coke is withdrawn from the stripping zone and transferred to a catalyst regeneration zone in which the catalyst is maintained in a fluidized bed (23) and contacted with an oxygen containing gas to effect combustion of the coke and removal of the coke from the catalyst and regeneration of the catalyst. The regenerated catalyst containing a minor amount of residual carbon is withdrawn from the regeneration zone and introduced to the reaction zone (5) and contacted with fresh light olefin feed. The careful control of the operating conditions in the regeneration zone provides removal of substantially all of the coke deposits at relatively low temperatures and an effluent flue gas with a low carbon monoxide content and low water content.

- suspending from a cable inside the pipe string a measurement assembly including sensor means, and lowering said measurement assembly into engagement with valve actuating means of the tester valve assembly, the arrangement being such that said sensor means is exposed to the fluid of said interval as a result of said engagement, irrespective of the position of the valve element; 
- exerting a succession of tensions and releases on the cable to operate said valve actuating means, said succession effecting successive changes in the position of the valve element, while measuring by said sensor means the modifications of fluid condition in said interval resulting from the operation of the valve element; and 
- releasing the measurement assembly from said valve actuat ing means upon completion of a predetermined cycle of tensions and releases exerted on said cable, the tensions within said cycle being lower than the tension to be exerted for actuating the valve element.
