Title: Afficheur a cristaux liquides pour projecteur de diapositives
Inventor: SOPER KEVIN JAMES
IPC: G03B23/00
Filed: 1998-03-05
Abstract: L'invention concerne un procédé et un dispositif permettant de projeter des images sur un écran ou une surface au moyen d'un projecteur de diapositives classique. Les projecteurs projettent des images contenues dans des diapositives. On insère donc un afficheur à cristaux liquides conçu pour être utilisé comme une diapositive normale dans un projecteur de diapositives et on l'utilise pour projeter des images ou des images en mouvement. Le projecteur projette simplement les images contenues à l'intérieur de l'afficheur et les affiche sur une surface appropriée. La taille et l'emplacement de l'image projetée peuvent être commandés par la distance entre le projecteur et la surface, l'image pouvant être mise au point par le dispositif optique convenable. La distance et le nombre de pixels à l'intérieur de l'afficheur déterminent la résolution de l'image. L'invention propose ainsi un procédé et un dispositif simples et peu coûteux, qui permettent de projeter de grandes images, ce qui n'était jusque-là possible qu'avec des récepteurs de télévision grands et chers.

Inventor: BOUCHER RAYMOND M G
IPC: A01N35/02
Filed: 1989-11-14
Abstract: Very potent,  stable,  odorless,  and phenol-free virucidal solutions are active at high dilution when used for  surface  decontamination  of  animate  and  inanimate objects.    The  virucidal  compositions  described  are efficacious  in a matter of minutes  against both the lipophilic and the more resistant hydrophilic viruses. The  three  active  ingredients  in  these  virucidal compositions  are  the  glutaraldehyde  monomer  in equilibrium with its hydrates and polymers, hydrogen-bonded glycol molecules to eliminate aldehydes odor, and an  anionic  surfactant  of  the  alkyl  sulfate,  alkyl sulfonate, alcohol sulfate or alkyl aryl sulfonate type. A  preferred  anionic  surfactant  would  be  the  Sodium Dodecyl  Sulfate  (SDS),  which  exhibits  strong  cidal synergism against the Herpes Simplex Virus type 1 when mixed at a concentration as low as 0.0005% in diluted glutaraldehyde  aqueous  solutions  (0.0025%).    Improved virucidal killing at higher dilutions of the same formula were  observed  with  the  more  resistant  Coxsackie  B viruses.   Because of the low concentration of active ingredients,  these  solutions  exhibit  a  very  low toxicity, making them suitable for topical applications as antiseptics.

Abstract: The power demand of a dynamic audio load is monitored, for example, by sensing the voltage level of the power supplying the audio load. An audio load control signal corresponding to the power demand is generated.      The audio load control signal is advantegously applied to a circuit for producing a side pincushion correction current, for modulating the side pincushion correction current by the audio load demand. The audio load modulated side pincushion correction current is used to modulate a horizontal deflection current in order to compensate for both side pincushion distortion and dynamic audio load induced raster width distortion. A filter network may also be provided for removing high frequency signal components from the audio load control signal.

Patent CA-2016301-A1 (CA)
IPC: H04R1/32
Filed: 1990-05-08
Abstract: Second-order gradient directional microphones, both toroidal and unidirectional, derived using a first-order gradient sensor and an acoustically reflecting surface are disclosed. The sensor is positioned with its axis illustratively orthogonal to and suspended a few centimeters from a large acoustically reflecting surface. The resulting sensor image is phase reversed resulting in a transducer that is a linear quadrupole. The linear quadrupole can be described by two dimensions, the distance corresponding to the sensor's dipole distance and twice the distance from the reflecting plane. If the reflecting surface is large enough or if the wall of an enclosure is used, the resulting microphone becomes a second-order gradient unidirectional microphone. A perfect match between the sensor and its image from a good acoustic reflector results in an ideal second-order gradient microphone with 3 dB beam width of ?33° and no grating lobes below about 3 kHz for a spacing from the reflecting plane of about 2.5 cm. Toroidal directional microphones are formed using two or more sensors and an acoustically reflecting surface.

Inventor: BRETON RICHARD E
IPC: B65H45/22
Filed: 1990-10-31
Abstract: An improved folder includes a first series of belts which grips and moves sheet material along converging deflectors to fold the sheet material.  As the space between the deflectors narrows, a second series of belts grips the sheet material and continues its movement between the deflectors.  The first series of belts includes a first plurality of tapes disposed on a first side of a fold line and a second plurality of tapes disposed on a second side of the fold line.  The second series of belts includes a pair of creaser belts which extend from between the tapes to an outlet portion of the folder.  The speed of movement of the tapes and creaser belts is coordinated by using speed signal generators which are driven at the speed of movement of the tapes and creaser belts.  A controller compares the speed signals and maintains a desired relationship between the speed of movement of the tapes and creaser belts.  It is believed that the creaser belts will usually be driven at the same speed.  However, the creaser belts may be driven at slightly different speeds in order to compensate for deformation imparted to the sheet material before it moved between the creaser belts.
