Title: Method and device for cleaning underwater pipes.
Inventor: RUFOLO PAUL G
IPC: B08B9/04
Filed: 1992-12-04
Abstract: A method of removing animal growth organisms and such foreign material from the inside surface of an underwater pipe extended at its outlet end into a wet well at a pumping shore station, by inserting a bladed cleaning device in the pipe at the wet well and pulling it to a spaced inlet end of the pipe, the cleaning device having stationary rigid circumferential and radial cutting edges suited to core chuncks of foreign matter free from the pipe surface and dice them into smaller pieces of the foreign material. The method further provides injecting fluid under pressure from the cleaning device toward the bottom of the pipe as a fluid stream of sufficient velocity for raising the foreign matter chuncks and pieces into suspension with water in the pipe, and pulling the cleaning device axially within the pipe back toward the wet well. The method further provides continuously removing such foreign matter chuncks and pieces from a containment area in the wet well via an air lift passageway extended vertically between the containment area and an overlying spillway disposal system by discharging compressed air continuously to the lower end of the passageway, this air lift action also serving to draw water and the suspended chuncks and pieces of foreign matter in the pipe toward and into the containment area and wet well.

Abstract: Usinage par décharge électrique dans lequel les conditions d'usingage sont mises à jour automatiquement de manière que le degré de décharge corresponde aux valeurs cibles. On détermine une condition d'usinage initiale P1, un degré de décharge électrique cible (une intensité de décharge normale par exemple) P2, ainsi qu'une constante P3 de calcul d'un nouvel état d'usinage. Les états d'usinage initiaux P1 sont stockés dans un registre D, lequel stocke les états d'exécution d'usinage. L'usinage commence sur la base des états ainsi stockés (S3). On obtient l'erreur (E) entre les données de détection P4 représentant le degré de décharge, et le degré de décharge cible (S7). On obtient le nouvel état d'usinage (A) en ajoutant le produit de l'erreur (E) multiplié par la constante PC (=C) à l'état d'usinage en cours (A) (S8). Ensuite, on répète ces étapes et on met à jour l'état d'usinage de manière que le degré de décharge corresponde au degré de décharge cible. On obtient le degré de décharge cible par un usinage d'essai.

Abstract: A low power signal buffer circuit for TTL signals includes a voltage reference controlled complementary MOSFET ("C-MOSFET") amplifier and a C-MOSFET inverter. The voltage reference controlled C-MOSFET amplifier receives a fixed reference voltage and a TTL input signal and provides a reference bias voltage. The C-MOSFET inverter has a pull-up P-type MOSFET which receives and is biased by the reference bias voltage, and a pull-down N-type MOSFET which receives the TTL input signal. The C-MOSFET inverter provides a TTL output signal with a substantially increased dynamic signal amplitude range. Current drain from the DC power supply for the buffer circuit decreases significantly as the TTL input signal state changes from "low" to "high" (e.g. logical "zero" to logical "one").

Abstract: An apparatus has first propellers (20) and second propellers (21) alternating with the first propellers. Each propeller has one or more helical biting edges (24a) protruding into a guide passage (28) through which a raw material (W) advances. The biting edges are formed along an inner periphery of each propeller at a predetermined lead angle so as to bite an outer periphery of the raw material (W). The apparatus further has a drive mechanism for rotating the first propellers (20) in a direction opposite to that in which the second propellers (21) are driven. The helical biting edges (24a) are inclined such that the raw material (W) may be forced towards a pressure vessel (2) by all the propellers, notwithstanding the opposite directions in which the first and second propellers are driven, so that a strong thrust is applied to the raw material, without causing any torsion of the material which is being forced towards the pressure vessel.

Abstract: There is disclosed the architecture for an all-optical network which employs a three level hierarchy using wavelength division multiplexing. At the lowest level of the hierarchy are Level-0 all-optical networks (36, 37, 38, 39). The Level-0 networks are "local" broadcast networks each of which supports a plurality of access ports and in which each access port can "hear" all the local traffic transmitted by all other access ports in the same Level-0 network. Each Level-0 network shares wavelengths internally, but there is extensive reuse of wavelengths among different Level-0 networks. The next higher level (62, 64), which is the intermediate level, Level-1, is essentially a wavelength router coupled with one or more of the Level-0 networks to provide a wavelength path to one or more directly connected Level-0 networks or, in combination with a Level-2 network (80), a light path to one or more Level-0 networks outside itself. The Level-2 are second level wavelength routing networks which provide light paths, as opposed to wavelength paths, between Level-1 networks. The Level-2 networks may be as simple as fiber trunks alone or they may employ frequency changing devices in addition to wavelength routers and/or spatial switches.

Abstract: An ECG recorder and playback unit which includes software-implemented digital signal processing filters which include a method for generating a heart rate variability (HRV) and late potential measurements. The HRV method in- dudes playing back the ECG data on the playback unit and a defining a reference point, usually corresponding to the R-wave peak, on each output ECG signal. An initial period is determined between the reference points. The period is then adjusted so as to align the reference points of the output ECG signals. The amount by which the ECG signals are adjusted is determined by computing a phase difference at a predetermined reference frequency and dividing the phase difference by the reference frequency to produce a period difference. The period is then adjusted by the period difference by adding the period difference to the measured period. The adjusted period is then used to compute the HRV measurement using statistical techniques. In an alternative embodiment of the HRV measurement, an interpolation technique is used to increase the accuracy of the reference point definition and thereby increase the accuracy of the period determination. A phase-ramp technique is employed to improve the frequency resolution of the ECG signal to improve the detection of late potentials.

Abstract: According to an automatic attitude correcting system of this invention, correction signals which are used to reduce control errors through a focus control, a tracking control, a tilt control, etc. are determined by measuring the amplitude of an RF reproduction signal reproduced from an optical disc at a predetermined area. For setting a correction signal value to be supplied to an attitude control mechanism such as an attitude control mechanism, a scanning signal whose signal level varies with time variation is supplied to a control mechanism driving circuit. The scanning signal varies in level at every one-revolution of the optical disc, and the amplitude of the RF reproduction signal is outputted from the optical head at every one-revolution of the optical disc, and measured at a predetermined angle for each level of the scanning signal. The maximum value is detected on the basis of the plural amplitude values thus measured, and the scanning signal value providing the maximum value is determined as a correction signal to be used in a reproducing operation. Therefore, in the reproducing operation, the control error of the control mechanism is excellently suppressed with the correction signal.
