Title: Web treatment system
Inventor: BUSKE WALTER E
IPC: F26B13/02
Filed: 1988-10-28
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE A web treatment system includes main housing structure, chamber structure in the main housing structure that defines a thermally insulated web treatment zone, and structure that defines a web inlet at one end of the web treatment zone and a web outlet at the opposite end of the web treatment zone, so that a web path through the web treatment zone between the web inlet and the web outlet is defined.  A series of elongated gas distributing nozzle bar structures are supported in the upper region of the web treatment zone above and along the length of the web path.  Each gas distribution nozzle bar structure has opposed end walls and elongated lower wall structure extending between the end walls across the width of the web treatment zone, an inlet port in one end wall and outlet port structure in the lower wall extending along the length of the gas distribution nozzle bar for directing flow of gas from the supply plenum downwardly toward the web path.  In each nozzle bar structure adjacent its inlet port is eddy creating structure and remote from the inlet port is flow stabilization structure such that the velocities of gas flows exiting from each nozzle bar structure are substantially uniform over the length of the nozzle bar structure and the width of the web treatment zone.

Abstract: ABSTRACT OF THE DISCLOSURE     An active sound attenuation system for combustion engine exhaust systems and the like is disclosed.  To protect the counter-noise acoustic wave generator from the environment of the medium propagation the undesirable noise, an acoustically tuned anti-noise chamber is interposed between the wave generators and the location of the medium with the undesirable noise.  To provide for global cancellation at the outlet end of the exhaust pipe, the anti-noise chamber has an annular opening disposed substantially in the plane of the exhaust pipe outlet thereby giving the undesirable noise and the cancelling noise an apparatus common source.

Title: Apparatus and method for determining cardiac output by thermodilution without injection
Inventor: WILLIAMS WILBUR R
IPC: A61B5/1495
Filed: 1989-08-23
Granted: 1995-04-04
Abstract: Heat is removed from the blood flow by heat exchange rather than cold-liquid injection; resulting temperature changes are monitored.  Flow rate is found from monitored temperature and known parameters related to the amount of heat removed.  Preferably heat is removed by pumping cold liquid into a sealed balloon or sheath along a catheter, which is in the blood stream.  The balloon acts as a heat exchanger; its design optimizes that function.  Temperature can be monitored by a thermistor or other sensor closer to the tip of the same catheter.  Alternatively it appears possible to use blood-temperature measurements taken just outside the balloon, or even within the balloon, if the system is calibrated to account for the relation between the blood flow rate and the heat lost from balloon to blood.  Heat removal can be either quasi steady-state or cyclical:  that is, either heat is removed semicontinuously by a low-temperature-differential exposure and resulting steady-state temperatures observed semicontinuously; or heat is removed periodically in brief high-differential exposures, and temperature changes tracked in defined time periods during or after each exposure.  In the latter case, a patient's heat balance can be maintained by alternately adding heat in protracted low-differential exposures.

Abstract: ABSTRACT OF THE DISCLOSURE            Protection method and protection device for detecting asynchronism during the synchronous starting of a syn-chronous machine.            During the run-up of high-power synchronous machines (6), such as those used in pumped storage plants, in gas turb-ines sets and so forth, unwanted alternating currents with slip frequencies between those of the phase swings and the nominal frequency (50 Hz)  of the synchronous machine (6) can also occur in the disturbed condition in addition to low-frequency plant-specific phase swings. These alternating currents  are  induced in the  field windings of the synchronous machine (6) as a consequence of an unwanted asynchronous starting and can lead to inadmissible heating of the synchronous machine and to overvoltages in the field circuit. Alternating voltages (U1) associated with the slip frequencies are detected from use of a sensing resistor (4) in the exciter current (if) of the synchronous machine (6), separated from the high-voltage potential in an isolating converter (10), subsequently filtered in a bandpass filter (11), con-trolled for constant amplitude in a function generator (12), triggered in a Schmitt trigger (13) and selected by means of two timing sections (15, 16). If a slip fre-quency   is detected uninterrupted for longer than a predeterminable minimum period  (T3),  field and high-voltage switches (5, 7) in the circuits of the synchro-nous machine (6) are opened by a RS flip-flop (19).

Abstract: Abstract:            Support web for roof foundation webs A support web is described for roof foundation webs which comprises a spunbonded web of polyester filaments. The spunbonded web has a basis weight of 50 to 100 g/m2 and a filament denier of 1 to 8 dtex.  It has been thermo-mechanically preconsolidated by means of a smooth calen-der and end-consolidated by means of a binder.  This produces a high tear propagation resistance and nail removal resistance and good dimensional stability at high temperatures. The spunbonded web is therefore particular-ly suitable for use as a support web for bituminized roof foundation webs.

Abstract: ABSTRACT      A garment, such as shirt, having a piece of material which may be of the same material as the shirt fastened along an upper edge to the front panel of the shirt so as to form a flap which normally hangs from about a mid-portion of the front panel. The fastening line provides a horizontal hinge line, and when hanging in the normal position, the flap covers the outer surface of the lower portion of the front panel of the shirt.  The outer surface of the flap together with the outer surface of the front panel of the shirt above the hinge line form a first display area.  When the flap is held in a raised position, the inside surface of the flap together with the outer surface of the lower surface of the front panel form a second display area.  A first part of a message or information is presented on the first display and a sequel part of the message or information is provided on the second display area.  Thus, the garment forms a novelty shirt in that after a person sees the first message, while the second message remains  hidden, the wearer or the other person may lift the flap to a raised position to let the person see the second part of the message.

Un signal RF modulé produit par un émetteur subit un abaissement de sa fréquence jusqu'à une fréquence intermédiaire relativement basse et le signal résultant est filtré et échantillonné par un convertisseur analogique-numérique à fréquence d'échantillonnage élevée. Le signal numérique résultant de la conversion est traité par un processeur qui produit une fonction d'amplitude mesurée et une fonction de phase mesurée correspondant au signal RF modulé. Une fonction de phase idéale correspondant au signal RF modulé est calculée et synthétisée à partir des fonctions d'amplitude et de phase mesurées. Cette fonction de phase idéale est comparée à la fonction de phase mesurée afin de déterminer laquelle de ces fonctions doit être utilisée pour calculer les erreurs de phase et de fréquence du signal RF modulé.

Abstract: A seat made of a plurality of adjacently positioned cushions  is characterized  by  each cushions having an envelope made  of  a  gas-tight elastic material.  Each envelope has a predetermined shape under a maximum gas pressure causing no elastic extension of the material.   The  envelope contains  a reduced internal gas pressure slightly less than  the  maximum gas pressure to allow the sagging of the predetermined shape.  The reduced gas  pressure  is  sufficient to prevent opposite walls  of  the  seat  to collapse  one against the other upon external pressure of a portion  of  a human  body.   The  material forming the envelope of the  cushion  has  an elasticity  sufficient  to stretch and to conform to the contour  of  said portion of the human body.
