Title: Agricultural combine
Inventor: MATOUSEK ROBERT A
IPC: A01F12/44
Filed: 1997-10-29
Abstract: An agricultural combine having an enlarged cleaning area for enhancing the handling capacity of the machine without increasing the outside configuration thereof.  The agricultural combine includes an elongated walled body arranged about and along an elongated separating mechanism.  The combine further includes a cleaning station having a generally horizonal sieve disposed below the separating station so as to directly receive materials passing therefrom.  The cleaning station further includes a blower assembly for directing a pressurized stream of air from an outlet end upwardly through the sieve thereby effecting a further cleaning function of the grain.  The clean grain passing through the cleaning station falls into a clean grain area from whence an elevator transports the clean grain an enhanced holding tank defined within the walled body of the combine. An apparatus is disposed proximate to and rearwardly of the outlet of the blower assembly for forcibly propelling material passing through and from the sieve away from the outlet end of the blower assembly.  The apparatus is fitted relative to the combine such that the outer configuration of the combine remains substantially unchanged while enhancing the cleaning capacity thereof.

Patent CA-2225390-A1 (CA)
Title: Silicon-based sleeve devices for chemical reactions
Inventor: CARRANO ANTHONY V
IPC: C12M1/00
Filed: 1996-06-17
Abstract: A silicon-based sleeve type chemical reaction chamber (41) that combines heaters, such as doped polysilicon for heating, and bulk silicon for convection cooling. The reaction chamber combines a critical ratio of silicon and silicon nitride to the volume of material to be heated (e.g., a liquid) in order to provide uniform heating, yet low power requirements. The reaction chamber will also allow the introduction of a secondary tube (45) (e.g., plastic) into the reaction sleeve that contains the reaction mixture thereby alleviating any potential materials incompatibility issues. The reaction chamber may be utilized in any chemical reaction system for synthesis or processing of organic, inorganic, or biochemical reactions, such as the polymerase chain reaction (PCR) and/or other DNA reactions, such as the ligase chain reaction, which are examples of a synthetic, thermal-cycling-based reaction. The reaction chamber may be used in synthesis instruments, particularly those for DNA amplification and synthesis.

Filed: 1998-09-28
Abstract: An audio frequency recovery--DC restorer circuit after demodulation that includes an operational amplifier, a diode, a capacitor and resistor circuitry arranged to supply a reference voltage signal Vref to the operational amplifier. The operational amplifier is also coupled with a demodulated audio frequency baseband signal via the capacitor.  The demodulated audio frequency baseband signal is in a filtered condition free of high frequency noise that may otherwise affect quality and having an average voltage Vavg at a level.  The operational amplifier clamps the demodulated audio frequency baseband signal above or below the Vref depending upon an orientation of the diode so as to set a new desired Vref and provide as output a clamped baseband signal whose amplitude and waveform is identical to the demodulated audio frequency baseband signal before the clamping except for having a new average voltage (new Vavg) that is at a level different from that of the average voltage of the demodulated audio frequency baseboard signal because of the new desired Vref.

Patent CA-2255688-A1 (CA)
Inventor: BAGLIN FRANK GEILE
IPC: C04B41/53
Filed: 1997-05-19
Abstract: On améliore les propriétés de matrices cémenteuses par un ou plusieurs de trois procédés, qui peuvent être exécutés séparément, séquentiellement ou selon n'importe quelle combinaison voulue. Dans chaque cas, un fluide supercritique est un solvant ou contient un solvant, pour un réactif chosi parmi deux réactifs ou plus, tel qu'un initiateur de polymérisation de monomère ou de polymère. On perfuse le mélange résultant dans la matrice dans des conditions supercritiques. On place l'autre réactif dans la matrice, par exemple, en l'incorporant à la pâte de ciment humide avant son durcissement. Lorsque le mélange a pénétré dans la matrice, les réactifs réagissent et modifie la matrice cémenteuse de la manière voulue. Le solvant lui-même peut être supercritique ou non, et si ce n'est pas le cas, on le mélange à un fluide supercritique qui peut être un autre solvant ou pas. Ainsi, on peut enduire et/ou étancher l'intérieur de la matrice au moyen, par exemple, d'un polymère, ou on peut rendre l'intégralité de la matrice cémenteuse étanche aux solutions salines aqueuses et augmenter sa ductilité. On peut également fabriquer un polymère contenant du métal.
