Patent CA-2084512-A1 (CA)
Title: Surround processor
Inventor: FOSGATE JAMES W
IPC: H04H20/89
Filed: 1991-06-05
Abstract: A surround processor includes a time constant processing circuit (56) for smoothing directional information signals from a detector (54) with continuously variable time constants in order to generate one or more control voltage signals. The time constants produced by the circuit are continuously variable and responsive to both the rate of change and the amplitude of the directional information signals, such that as the difference between the controlled voltage signals and the directional information signals increases, the value of the time constants decreases to permit the control voltage signals to closely follow the directional information signals, and as the difference between the control voltage signals and the directional information signals decreases, the value of the time constants increases so that variations in the control voltage signals are smooth.

Title: Pre-prepared paster patterns
Inventor: PADILLA EDWARD R
IPC: B65H19/10
Filed: 1992-12-09
Abstract: PRE-PREPARED PASTER PATTERNS                   Abstract of the Invention A pre-prepared paster pattern designed to effectively create a splice between the first web of a first roll of paper feeding into a high speed printing press and the leading edge of the second web of a second replacement roll of paper. The paster pattern comprises a first extensive paper layer having two generally triangularly shaped portions adapted on a first side to be adhesively connected to the end portion of the replacement roll and to a web portion of the replacement roll spaced from the end portion. An array of pressure sensitive adhesive layers are applied to the second and opposing side of the first paper layer and are adapted to adhere to the first web of the first roll while the first web is being fed into the high speed printing press. A very tacky adhesive layer is applied to the second side at the apex of each triangular portion and is protected by a removable cover or release paper layer. A second extensive cover or release paper layer overlies the first paper layer and is releasably adhered thereto. The second layer is designed to protect the pressure sensitive adhesive on the first layer during non-splicing operations whereby on removal of the second layer, the pressure sensitive adhesive is undamaged and has maximum adhesive properties so as to effect reliable splices between the webs of the rolls.

Abstract: A voice communication device provided with a chirp signal generating means and a training control means in addition to an echo canceler for canceling acoustic echoes senerated in a hand-free speech space. The chirp signal generation means gen-erates chirp signal suitable for training the echo canceler initially.  The training control means makes the chirp signal generation means generate chirp signal and makes a hand-free speaker emit the shirp sound corresponding to the chirp signal when a prede-termined condition for starting a hand-free speech is satisfied. And further, trains the echo canceler initially according to the chirp sound.

Title: Gas-solid contacting method
Inventor: GOODES CHRISTOPHER GEOFFREY
IPC: B01D53/10
Filed: 1991-08-02
Abstract: A gas scrubbing process is disclosed whereby particulate material is contacted with a high velocity exhaust gas stream to reduce the resistance to mass transfer attributable to the diffusion boundary layer and provide higher mass transfer rates. The process is particularly suited to the scrubbing of gaseous fluorides from aluminium smelter pot exhaust gas with alumina. Addi-tionally, it has been found that the fines fraction with a particle size of preferably less than 45 µm adsorbs or chemisorbs a dispro-portionate amount of contaminant trace metals from the exhaust gas stream. To avoid recycling these trace metals contained in the exhaust gas back to the smelter pot the fines fraction may be elutriated from the coarse fraction.

Title: Truncation error correction for predictive coding/encoding
Inventor: KUSTKA GEORGE J
IPC: H04N7/50
Filed: 1993-06-25
Abstract: TRUNCATION ERROR CORRECTION FOR PREDICTIVE CODING/ENCODING          Abstract Apparatus for eliminating the truncation errors associated with a multiplicative leak factor employed in a predictive coding arrangement adds a temporally varying control signal that affects the leak factor multiplication output. Specifically, in one embodiment the leak factor multiplication output is modified by arbitrarily changing, or dithering, the level of the mean signal. In another embodiment, the leak factor multiplication output is modified by effectively dithering the leak factor itself. The latter is accomplished by adding the varying control signal prior to the truncated division which occurs in the leak factor multiplication process.     FILE:gjkus009.cn

Title: Lamp having interference-fit metallic bases
Inventor: SPAULDING DENNIS D
IPC: H01K1/46
Filed: 1993-09-24
Abstract: ABSTRACT      A lamp including a glass envelope having a base fitted at each end portion thereof.  Each lamp base includes a metallic base shell having an annular flange.  The annular flange is heated prior to fitting over the end portion of the envelope so as to increase the inner flange diameter.  Cooling of the annular flange after fitting reduces the flange diameter thereby providing an interference fit with the end portion.  The lamp base is retained on the end portion without the need for basing cement.  In order to accommodate variations in the diameter of the lamp seals, an annular rib is formed on the inner surface of the flange.  After cooling, the annular rib forms an interference fit with the lamp end portion.

Abstract: Lors de l'utilisation de certains appareils électriques il n'est pas toujours évident que les appareils fonctionnent bien, surtout lorsque les appareils ne font pas de bruit ou n'activent aucune lumière ou encore dans le cas des appareils qui ne sont pas à la vue de l'utilisateur et qui ne produisent pas d'effets évidents. Dans le cas d'un chauffe-moteur par exemple, rien ne dit que celuici fonctionne bien lorsqu'il est branché. Il faut donc à ce moment vérifier la continuité électrique pour s'assurer de son bon fonctionnement. Certains appareils de vérification indiquent la continuité seulement lors du branchement ou d'autres encore ne donnent que la présence de tension électrique. Dans la présente invention, l'appareil donnera la présence de continuité et de tension électrique pendant toute la durée de l'utilisation. Cet appareil détectera la présence du champ magnétique produit par le courant alternatif, ce qui est une manière indirecte pour déterminer s'il y a continuité.
