Title: Reservoir de stockage de liquides cryogeniques
Inventor: NOBLE STEPHEN DUNCAN
IPC: F17C1/00
Filed: 2003-04-02
Abstract: Le réservoir de stockage pour liquides cryogéniques de l'invention comprend une cuve de sonde délimitant un espace mort. La cuve de sonde communique, par une conduite creuse, avec une conduite de remplissage qui achemine le liquide cryogénique vers un espace cryogénique. Le point de jonction de la conduite creuse et de la conduite de remplissage présente une certaine aire de section transversale. La partie située en aval du point de jonction, à l'intérieur de la conduite de remplissage, mesuré par référence au sens d'écoulement du liquide cryogénique, au cours d'une opération de remplissage de l'espace cryogénique, présente une aire de section transversale supérieure à celle du point de jonction. Cette configuration crée au point de jonction, pendant une opération de remplissage, une réduction de la pression qui provoque un écoulement net de matière de l'espace mort, pendant toute la durée de l'opération de remplissage. Une fois le réservoir de stockage rempli de liquide de sorte que le liquide cryogénique redescende dans la conduite creuse, l'aire de section transversale plus petite de la conduite creuse, comparée à la conduite de remplissage, provoque une réduction de l'écoulement du liquide cryogénique, laquelle réduction est détectée par la pompe de remplissage qui arrête d'alimenter l'espace mort. L'invention concerne en outre un moyen de drainer la cuve de sonde avant et pendant le remplissage du réservoir de stockage.

Abstract: An internetwork communication system provides communication from a first local area network to a second, ring-type, local area network via a bridge.  The bridge receives a frame from the first local area network and transmits a dummy frame followed by an internetwork transfer frame to the second local area network.  The internetwork transfer frame defines a node of the second local area network as a distant apparatus (receiver) and a node of the first local area network as a self apparatus (sender).  The bridge later receives the dummy frame from the second local area network, after transmission of the dummy frame around the ring, and deletes the dummy frame and the internetwork transfer frame received following the dummy frame so that the communication in the second local area network does not circulate indefinitely around the ring.  As an alternative to using a dummy frame, the bridge can receive the internetwork transfer frame, after circulation around the second local area network, and compare the distant apparatus of the received internetwork transfer frame with a stored distant apparatus address.  When the received distant apparatus address matches the stored distant apparatus address, the bridge deletes the internetwork transfer frame from the second local area network.

Abstract: Abstract of the Disclosure A  process   for   forming   a   single   trench   MOS transistor/capacitor cell for  analog  signal  processing, and  the  resulting  structure,   are  disclosed.     The transistor is formed by forming a first  trench  in  the semiconductor substrate, lining the trench with a layer of insulating material, a layer of conducting material,  and filling the trench with a layer of insulator.   A doped region is formed adjacent the trench, which serves as a transistor source.  A second trench is then formed which extends  through  and excavates  a  portion  of  the  first trench. The second trench is lined with a layer of doped material and insulator.   The doped material is isolated from the conductive layer lining the first trench.   The second trench is then filled with a body of conductive material.  The layer of doped material lining the second trench serves as  the  transistor  drain and a capacitor output is extracted from the body of conductive material. The  resulting  structure  acts  as  a  trench  gate  MOS transistor having a capacitor output in series with the transistor drain.   Further,  a  process  is  disclosed to include  a  trench  gate  complementary  transistor  in  an adjacent  trench  structure.   A complementary  transistor circuit  with  a  series  connected  capacitor  is  thereby obtained.

Title: Echo canceller having fir and iir filters for cancelling long tail echoes
IPC: H04B3/23
Filed: 1990-02-22
Abstract: ABSTRACT OF THE DISCLOSURE An echo canceller comprises a finite impulse response filter (6) connected to the incoming port of a hybrid (1), and a tail canceller (7) which includes an infinite impulse response filter (24; 40) having a multiplier (14; 33) for recursively multiplying an output digital symbol from the tapped-delay line (8) of the FIR filter with an attenuation coefficient R. A digital symbol from the IIR filter or one from the tapped-delay line (8) is multiplied with a tap-weight coefficient Ci and summed with the outputs of tap-weight multipliers of the FIR filter to produce a replica of an echo symbol, which is subtracted from a digital symbol yn from the outgoing port of the hybrid (1), producing a residual echo symbol en. The coefficient Ci is derived from correlation between residual echo en and a symbol from the tapped-delay line. In one embodiment, symbol from the tapped-delay line is further delayed (17) for a unit interval on the one hand, and multiplied (18) with coefficient R on the other, the difference between them being detected (19) and multiplied (20) with a coefficient K, which is either sgn(Ci) or 1/Ci, to generate a multiplied difference. Correlation is detected (22) between the difference and residual echo en to derive the coefficient R. In a second embodiment, symbol from the tapped-delay line is further delayed (36) for a unit interval and multiplied (37) with K to produce a delayed-multiplied symbol. Correlation is detected (35) between it and residual echo en to derive the coefficient R.

Abstract: An improved switch-mode power supply is disclosed having a direct current power source, a transformer with a primary winding, at least one secondary winding and a core, first and second switching transistors and series with the primary winding of the transformer and drive means for generating signals to switch on the switching transistors to complete a circuit through the direct current power source, the switching transistors and the primary winding. In the improved circuit, a connection is provided through a diode to complete a circuit through the first switching transistor and part of the primary winding on activation of the drive means, drawing energy from a junction between two reservoir capacitors in series.   The current from this circuit generates a field in the core of the transformer which is sensed by an auxiliary winding on the transformer connected to the second switching transistor.  The signal generated in the auxiliary winding switches on the second switching transistor, allowing a circuit to be completed through both switching transistors and the entire primary winding of the transformer.  In a further embodiment of the circuit particularly useful in push-pull converters, third and fourth switching transistors are also provided in series with the primary winding of the transformer to complete a second circuit through the direct current power source, the third and fourth switching transistors and the primary winding.   The drive means sends two series of pulse-width modulated  drive  pulses,  the  first  series switching on the first switching transistor in order to complete a circuit ultimately through the first and second switching transistors and the whole of the primary winding in one direction, and the second series of pulses, 180- out of phase from the first, to switch on the third switching transistor,  in order to ultimately complete a circuit through ths third and fourth switching transistors and thQ   whole of the primary winding in the opposite direction.  A rebalance winding  on the core of the transformer and related circuitry are also provided where necessary to replace  energy  drawn  from  the  junction  between  the reservoir capacitors to maintain the reservoir capacitors in balance.
