Patent CA-2136293-A1 (CA)
Title: Arrangement for active sound damping
Inventor: GEISENBERGER STEFAN
IPC: F01N1/06
Filed: 1994-11-21
Abstract: It is known in the state of the art to dampen noise emissions by means of "anti-sound".  In the gas exhaust installations of combustion machines, this is realized most often in that the exhaust gas flowing in the gas exhaust installation is charged with "anti-sound" produced by loudspeakers (12).  However, such arrangements are  disadvantageous in that the flow of hot exhaust gases reduces the service life of the loudspeakers, or that such measures are insufficient for actively damping the sound. The invention therefore presents an arrangement that avoids the disadvantages that exist in the state of the art.  According to the invention, this is achieved in that the gas exhaust tube (10) ends in one of the two chambers of a double chamber box (17), and that a bass reflex tube (21) protrudes into this chamber of the double chamber box (17).  The excellent sound cancellation at low loudspeaker output is achieved because the sound cancellation takes place in the chamber of box (17), where the ends of the bass reflex tube (21) and the gas exhaust tube (10) terminate, and that the radiation axis S intersects the center line M in space A between the two tubes (10, 21) or in tube (21), and the distance L between the dividing wall (18) and center line M is 75% of the largest diameter extension of loudspeaker 12.

Title: Method and apparatus for measuring psychotherapy outcomes
Inventor: BRILL PETER L
IPC: G16H20/70
Filed: 1993-08-23
Abstract: A method and apparatus for measuring a patient's psychotherapy progress is provided. Initial patient mental health is measured by administering a questionnaire measuring three psychological variables. The three psychological variable measures are combined into a mental health index (69). Following a number of sessions of psychotherapy, the patient's subsequent psycho-logical condition is again measured using the three psychological variables.  Patient session records (42) are stored in a large data-base (20). Patient progress can thus be compared versus patient initial psychlological condition, typical patient outcomes as stored in the database (20), and patient improvement as a function of a number of sessions of psychotherapy can be determined. The system further provides a case manager with a measure of the effectiveness of continued psychotherapy sessions, and a basis of comparison of various psychotherapy providers.

Patent CA-2154883-A1 (CA)
Title: Digital audio limiter
Inventor: FIELDER LOUIS DUNN
IPC: H03G11/00
Filed: 1994-02-15
Abstract: The invention relates to limiting the peak amplitude of an audio signal in one or more frequency subbands while preserving the apparent loudness. Applications such as a Studio-Transmitter Link (STL) for broadcasting sometimes use perceptual coding to deliver an audio signal originating from a studio to a broadcast transmitter. The peak amplitude of the audio signal will have been limited by means of a limiter or otherwise, and a perceptual encoder reduces the informational capacity requirements of the audio signal for transmission across a link to a broadcast transmitter. A perceptual decoder receives the coded signal from the link and reproduces the audio signal for the broadcast transmitter. The peak-amplitude of the signal reproduced by the perceptual decoder may sometimes exceed the capabilities of the broadcast transmitter even though the peak amplitude of the audio signal input to the perceptual encoder is properly limited. This increase in peak level is referred to as "peak-level increase" or PLI. Transmitter overload resulting from PLI can create audible distortion and/or impermissible broadcast conditions such as excessive FM deviation. Various embodiments of apparatus and method are described which estimate PLI caused by signal processing such as perceptual coding and which apply corrective gain to the portions of the audio signal bandwidth so as to limit peak amplitude while preserving apparent loudness.
Patent CA-2157015-A1 (CA)
Title: Inhibitors and target molecule co-localization
Inventor: ROSSI JOHN J
IPC: C12Q1/70
Filed: 1994-12-02
Abstract: The invention provides mechanisms for the co-localization in a living cell of a target molecule and of an inhibitor for the target molecule. The invention also provides novel chimeric tRNALYS-ribozyme molecules that compete effectiely with tRNALYS for HIV-1 reverse transcriptase binding sites. The chimeric human tRNALYS-ribozymes inhibit reverse HIV transcription by delivering inhibitors such as ribozymes of HIV-1 reverse transcriptase directly to the virion particle and render it non-functional. The chimeric molecules of the invention thus serve as highly specific non-toxic therapeutic agents and vaccines for viral, including lentiviral, infections. These chimeric molecules also reveal a novel, site specific RNA cleaving activity of HIV-1.

Title: Method of making optical fiber having depressed index core region
Inventor: BERKEY GEORGE E
IPC: C03B37/012
Filed: 1995-11-01
Abstract: Disclosed is a method of making an optical fiber preform having at least one annular region of depressed refractive index.  A tube of silica doped with fluorine and/or boron is overclad with silica soot.  A core rod is inserted into the overclad tube and the resultant assembly is heated while chlorine flows between the tube and the core rod to clean the adjacent surfaces.  When the soot consolidates, the tube collapses onto and fuses to the rod.  The resultant tubular structure is provided with cladding and drawn to form an optical fiber which exhibits low attenuation as a result of the low seed count at the interface between the inner core and the region that is doped with florine and/or boron.

Abstract: Une colonne de transfert de masse ou d'échange thermique (20, 120, 220, 320) est pourvue d'un dispositif de répartition de vapeur (26, 126, 226, 326) possédant dans un mode de réalisation, une chambre de circulation (32, 132, 232, 332) faisant circuler un flux de vapeur autour de la périphérie intérieure de la colonne (20, 120, 220, 320). La chambre de circulation (32, 132, 232, 332) possède une pluralité d'orifices de sortie (40, 140, 240, 340) éloignés les uns des autres et permettant à des parties du flux de vapeur de s'introduire dans l'intérieur ouvert de la colonne au niveau d'une pluralité d'emplacements. Les flux de vapeur sortant de la chambre de circulation (32, 132, 232, 332) possèdent une vitesse suffisante pour provoquer leur mélange turbulent, ce qui répartit la vapeur plus uniformément à travers la section transversale horizontale de la colonne (20, 120, 220, 320). La vapeur ascendante et répartie uniformément peut ensuite entrer en interaction avec le liquide de façon plus efficace dans un zone supérieure (24) pouvant comporter des plateaux ou une garniture structurée ou non. Dans un aute mode de réalisation, le dispositif de répartition de vapeur (426) définit un canal d'écoulement (442) présentant une section transversale décroissante communiquant avec une partie inférieure généralement ouverte dudit dispositif (426). La zone décroissante du canal d'écoulement (442) expulse le flux de vapeur du dispositif de répartition (426) de façon uniforme, de manière à effectuer une répartition plus régulière à travers la section transversale horizontale de la colonne (420).
