Abstract: Cette invention concerne un séparateur de débit (36) en forme de Y, lequel assure le passage d'un fluide servant à la fabrication du papier et comprenant des fibres tout en minimisant les risques d'occlusion. Ce séparateur comprend une surface plane (68) opposée à la jambe (44) du Y, là où le débit se divise et part dans les deux branches (46) dudit Y. Une surface globalement plane et rectangulaire est placée en face de la jambe du Y du séparateur de débit, laquelle permet de diviser le débit de manière équilibrée et d'éliminer tout endroit où les fibres pourraient s'amasser et bloquer ainsi le débit dans le séparateur. Le séparateur permet ainsi de réguler le débit vers deux tubes de dilution à l'aide d'un seul clapet, tandis que l'utilisation d'un seul passage de débit permet de réduire les risques d'obstruction ainsi que le coût du clapet. Ce séparateur de débit est fait d'acier inoxydable et obtenu par coulage. Afin d'obtenir des passages de débit lisses, on utilise un procédé connu dans le commerce sous le nom d'Extrudehone.

Granted: 2002-10-15
Abstract: A Class D amplifier having a low-level audio signal feeding the negative input of an Integrator via an input resistor. Said Integrator feeds a Comparator having well-defined Hysterisis. Said Comparator output is connected to a First Level Shifter in order to convert a ground-referenced signal to a negative-voltage-rail-referenced signal so as to provide a drive signal for a First Switching Device which is connected to a Negative Rail Voltage (Vminus) and an Output, where said Output is defined as the junction of said First and a Second Switching Device and said junction having a time averaged signal of high power capable of driving a low impedance load such as a loudspeaker. A Second Level Shifter is provided so as to drive said Second Switching Device which is connected to the Positive Rail Voltage (Vplus) and said Output. The signal from said Second Level Shifter is floating and referenced to said Output. The signal at said Output is kept in phase with the signal of said Second Level Shifter, yielding very high .DELTA.v/.DELTA.t immunity at said Output. A Feedback Resistor is provided from said Output to the negative input of said Integrator in order to ensure self oscillation and to provide negative feedback in order to reduce distortion and the effective output impedance (increasing the damping factor). A Low-Pass tilter between said Output and said Load is desirable to reduce unwanted RF and switching noise.

Title: Procede de formage et de percage d'un tube
Inventor: ASH STANLEY P
IPC: B21D26/02
Filed: 1997-07-09
Granted: 2002-09-10
Abstract: Dans cette invention, pour former à froid un tube de métal dans une pièce estampée, on remplit le tube d'une substance liquide à changement de phase, on congèle la substance à changement de phase, on bouche le tube contenant la substance à changement de phase, et on estampe le tube dans une matrice. Lors de l'estampage, la compression de la substance à changement de phase force les parois du tube à épouser les contours de l'empreinte de matrice, ce qui rend superflu la mise du tube sous pression avant ou après estampage. De plus, le solide à l'intérieur du tube soutient la paroi de celui-ci lors du perçage destiné à former un trou dans le tube; il une résulte une déformation moins importante autour du trou que dans le cas de perçage d'un tube non rempli de solide. Après estampage ou perçage, on fait fondre la substance à changement de phase pour qu'elle sorte du tuyau. En outre, pour percer le tube, on forme une zone de renflement, puis perce le tube dans la zone de renflement et on enfonce en même temps le tube pour aplatir sensiblement la zone de renflement.

Abstract: A feed-forward amplifier is provided, which can implement a satisfactory linearity immediately after its activation, which has a high productivity and exhibits less long term fluctuations of its characteristics during the operation. In the feed-forward amplifier, the transfer function of a path from an input terminal to a directional coupler via a main amplifier and the transfer function of a path from the input terminal to the directional coupler via a first delay means are automatically controlled so as to be equal in amplitude but anti-phase relative to each other, and the transfer function of a path from the main amplifier to an output terminal via a second delay means and the transfer function of a path from the main amplifier to the output terminal via an auxiliary amplifier are automatically controlled so as to be equal in amplitude but anti-phase relative to each other.      Still further, at the time of the activation of the feed-forward amplifier, control values of a first vector adjuster are set to values stored in a first nonvolatile memory in accordance with a temperature measured in the vicinity of the main amplifier by a first temperature sensor, and control values of a second vector adjuster are set to values stored in a second nonvolatile memory in accordance with a temperature measured in the vicinity of the auxiliary amplifier by a second temperature sensor.

Abstract: A temperature stabilized tapered fiber optic component is produced, such as a fiber optic coupler or a fiber optic filter. In the case of the component such as a coupler, at least two fibers are fused and tapered to achieve a desired taper profile with suitable mechanical and wavelength properties. In the case of a component such as a fiber filter, only one fiber is tapered. Once the component is formed, it is solidly secured to a rigid substrate that produces a mechanical stress such as to compensate for any modal phase shift of the component due to temperature variation. Also, the mechanical phase dependence of the component may be adjusted in relation to the substrate to provide the desired temperature compensating effect. Preferably, both these features are used to achieve the best possible temperature stabilization.

Title: Swivel drive arrangement
Inventor: POLLACK JACK
IPC: B63B27/24
Filed: 1998-12-02
Granted: 2004-04-06
Abstract: The invention relates to a vessel comprising a hull (1) and a cylindrical turret well (3). The vessel can weathervane around a geostationary turret (4) located in the turret well. At least one swivel (7) is supported on the turret. According to the invention, the inner wall (10) of the swivel is connected to rotation drive means (18), which can thereby be reduced in size and which allow the full swivel weight to be transferred directly to the turret. In one embodiment the inner wall (10) of at least one swivel, preferably the walls of a swivel stack, is rotatably connected to a swivel support structure on the turret vi a a bearing (17). The rotation drive means (18) are adapted for rotating the inner walls (10) in conjunction with the vessel. In this way relative displacements between the swivel (7) and the turret (4) are reduced such that the layout of the pipe lines connected to the swivel can b e simplified by the omission of expansion loops. As the weight of the swivel is carried by the turret, the rotation and pipe support structure can be relatively small. In a second embodiment the outer walls of the swivel stack are fixedly connected to the turret. In this way separate rotational drive means for the outer walls can be omitted.
