Abstract: P R ? C I S La présente invention concerne un cylindre largable, comportant des bras déployables articulés à une des extrémités du cylindre et une vis sans fin motorisée destinée à faire passer les bras, au cours de la descente aérienne du cylindre, d'une position repliée le long du cylindre à une position déployée sensiblement perpendiculaire au cylindre afin de freiner la descente de ce dernier. Un premier capteur d'impact associé à une unité logique commande la rétraction des bras le long du cylindre, lorsque celui-ci a atteint le sol après sa descente aérienne. Le cylindre est alors en état de veille. Un second capteur de vibration de sol associe à la même unité logique commande le déploiement des bras pour passer de l'état de veille à un état actif, dans lequel les bras supportent le cylindre sur le sol, lorsqu'un véhicule lourd passe à proximité du cylindre ainsi supporté.

Granted: 1991-02-05
Abstract: "CARRIER RECOVERY CIRCUIT FOR OFFSET QPSK                 DEMODULATORS"                       ABSTRACT OF DISCLOSURE A carrier recovery circuit comprises a voltage-controlled oscillator with a .pi./2 phase shifter coupled to it for generating carriers of quadrature phase relationship. First and second phase comparators respectively detect phase differences between an offset QPSK modulated signal and the carriers of the quadrature phase relationship. Signal from the first phase comparator is delayed by a 1/2 symbol duration and applied to one input of a quadri-phase detector having stable phase angles at .pi./4, (3/4).pi., (5/4).pi. and (7/4).pi. radian and signal from the second phase comparator is applied to the other input of the quadri-phase detector. A bit timing recovery field (1010 ....1010) of the second channel is detected from the output of the second phase comparator. Signal from the quadri-phase detector is applied to a loop filter and thence to the voltage-controlled oscillator during the time when a bit timing recovery field (BTR) of the second channel is not still detected. To stabilize the operation of the carrier recovery loop of the circuit, the output of the second phase comparator from which that BTR is detected is briefly applied to the loop filter in response to the detection of a BTR of the second channel, instead of the signal from the quadri-phase detector.

Abstract: Abstract of the Disclosure A digital wipe generator has a digital waveform generator to generate x and Y digital waveforms from a composite sync signal.  A digital wipe solid generator processes the X and Y digital waveforms to produce a digital wipe solid waveform.  The wipe solid generator has a circle generator using a square root function which preshifts the sum of the squares prior to access to a look-up table, and then post shifts the output of the look-up table by one-half the amount of the preshift to produce a desired curve pattern for the digital wipe solid waveform.  The digital wipe solid waveform is input to mixer circuits where it is processed to produce an anti-aliased key signal for mixing external video signals, the anti-aliasing being based upon an interpolation/decimation scheme using fractional bits of the digital wipe solid waveform. The output of the mixer circuits is a desired wipe transition.

Abstract: ABSTRACT          The invention provides a sampling process and apparatus therefore for the control of the addition of expensive conditioning material, referred to as polymers, to suspensions, sludges and the like, particularly sewage sludge, to facilitate its dewatering.  The process employs a viscometer able to measure rapidly the shear stress of the sludge and obtain a typical peak value characteristic of optimum conditioning of the sludge.  The process and apparatus also operate in a new mode involving charging a sample vessel with unconditioned sludge, taking a measurement to obtain an "unconditioned" signal, and then filling with conditioned sludge and obtaining a "conditioned" signal, the unconditioned signal indicating the solids content of the sludge and being used to modify the signal controlling the polymer flow and therefore the dosage to compensate for this change.  The viscometer rotor and the vessel interior are rinsed to remove the conditioned sludge before a fresh batch of unconditioned sludge is introduced.  The system employs a minimum-seeking algorithm to minimise polymer usage.          Changes are made to the polymer flow rate when the conditioned signal change is greater than a dead-band straddling the optimum value, the minimum-seeking also taking place within the dead-band.  It is sometimes found that the peak value/polymer flow rate characteristic includes a secondary peak, whereby the peak value reduces with increase of polymer flow, and this potentially unstable condition is detected and corrected.

Granted: 1994-10-18
Abstract: This invention relates to a method of conducting a joining/coating operation which provides good wetting of metal-comprising substrate surfaces by metal-comprising filler/coating materials while reducing the rate of metal oxide formation. The joining/coating operation is carried out in a controlled oxidizing atmosphere having an oxidation capability greater than that required to oxidize a metal-comprising filler material used for joining or a metal-comprising coating, but having less oxidation capability than that of air. Typically the controlled oxidizing atmosphere consists essentially of nitrogen and oxygen, wherein the oxygen concentration is controlled at a set point. The range of the setpoint corresponds with an oxygen concentration which can range from greater than about 10 ppm to about 100, 000 ppm, depending on the application. When a flux is used and the joining technique is reflow soldering, the setpoint for oxygen concentration can range from greater than about 100 ppm to less than about 50,000 ppm of oxygen, depending on the application, with a preferred range from about 500 ppm to about 10,000 ppm. When a flux is used and the joining technique is wave soldering, the setpoint for oxygen concentration can range from about 1,000 ppm to about 100,000 ppm of oxygen depending on the application, with a preferred range from about 10,000 ppm to about 20,000 ppm. Joining/coating operations conducted without use of a flux require a joining/coating atmosphere having a lower oxidation capability, but still capable of oxidizing the metal-comprising filler material/metal-comprising coating material.
