Title: Biological reaction processes
Inventor: DRUMMOND HUMPHREY
IPC: C12N1/00
Filed: 1992-03-09
Abstract: A process for maintaining a high rate of mass transfer of nutrients contained in a liquid feed stream to a biofilm of microorganisms supported on a bed of particulate matter. The microorganisms in the biofilm are subjected to a continuous, uniform flow of the liquid feed stream and a countercurrent flow of respiratory air so as to support biofilm growth. The bed is periodically pulsed with air at a pressure sufficient to shed microorganisms from the biofilm and at intervals sufficient to avoid preferential channelling of the liquid feed stream through the bed and/or to disrupt and rearrange the bed of particulate matter.

Title: Recepteur pouvant reduire la consommation d'energie dans une boucle a asservissement de phase
Inventor: MINAMI YOICHIRO
IPC: H03D3/24
Filed: 1993-10-18
Abstract: Dans un récepteur servant à démoduler une onde modulée par un signal de données numériques injecté dans un canal choisi à l'avance afin de produire un signal de données reproduit au moyen d'un signal de fréquence locale, un VCO (oscillateur à tension variable) et un circuit PLL (circuit de verrouillage de phase) sont activés de façon intermittente par rapport à une fréquence décalée entre une fréquence de canal et la fréquence locale. Le circuit PLL est activé pour une période déterminée par la fréquence décalée avant la réception d'un canal choisi à l'avance, tandis que le VCO est activé pendant que le circuit PLL est actif et pendant la réception du canal choisi à l'avance. Lorsque la fréquence décalée n'est pas comprise dans une plage prédéterminée fixée par des fréquences décalées également prédéterminées, la durée de l'état actif du circuit PLL devient longue, sinon elle devient courte. La fréquence décalée est détectée par un détecteur de fréquence qui produit un signal de commande, lequel apparaît seulement lorsque la fréquence décalée est à l'extérieur de la plage prédéterminée. Le signal de commande est envoyé à un circuit de commande pour commander les opérations de conservation d'énergie du VCO et du circuit PLL.

Title: Method and apparatus for bending glass sheets
Inventor: WAMPLER DAVID M
IPC: C03B23/03
Filed: 1992-06-17
Abstract: The present invention relates to a female press bending ring (50) for use in the press bending of glass sheets outside of a furnace, and more particularly to a female press bending ring which is suitably heated by heater elements (69) during the bending cycle to regulate the transfer of heat between the peripheral margin of the glass and the female bending ring with which it is in contact. By so doing, near-edge tension and edge stresses are greatly reduced, thereby reducing chill cracking and glass breakage during and after production. The female ring may be covered by a layer (78) of fiberglass cloth or the like to provide a smooth resilient for engaging the glass sheet.
Patent CA-2112821-A1 (CA)
Title: Device and method for multi-phase radio-frequency ablation
Inventor: DESAI JAWAHAR M
IPC: A61N1/32
Filed: 1992-06-04
Abstract: Multi-phase RF ablation employing a two-dimensional or three-dimensional electrode array (501) products a multitude of currents paths on the surface of the ablation zone. This results in a uniform lesion with a size defined by the span of the electrode array. An orthogonal electrode catheter array suitable for cardiac ablation is used in conjunction with a two-phase RF power source to produce uniform square-shaped lesions of size 1,2 cm2. Lesions of larger size are created by successive adjacent placement of the square-shaped lesions. A temperature sensor (531) at the electrode tip allows monitoring of ablation tem-perature and regulation thereof to minimize the electrode tips from being fouled by coagulum.

IPC: C07D493/22
Filed: 1994-01-18
Abstract: ABSTRACT OF THE DISCLOSURE      An intensive long-term investigation of marine organisms as sources of new anticancer drugs has led to the isolation and structural elucidation (primarily by high field NMR and mass spectrometry) of halistatin 2, a new polyether macrolide of the halipyran-type,  from  the  Western  Indian  Ocean sponge Axinella cf. carteri (Dendy). Halistatin 2 (1.4 x 10-6% yield) caused the accumulation of cells arrested    in    mitosis,    inhibited    tubulin polymerization,  and  inhibited  the  binding  of radiolabeled  vinblastine  and  GTP  to  tubulin. Further,   Halistatin   2   displayed   significant activity against selected human tumor cell lines.

Patent CA-2136681-A1 (CA)
Title: Reciprocating piston pump
Inventor: YOSHIMOTO ERNESTO
IPC: F04B49/035
Filed: 1994-11-25
Abstract: A pump has a piston which is reciprocatingly moved vertically inside a tubular casing to extract fluid, say, from the bottom of a well.  The piston, attached to a motor for driving it, has a horizontally extending base plate with a central opening provided with a plug functioning as a check valve. When a fluid is taken in by the pump, the plug is lifted and the fluid is guided into a reservoir above the base plate.  When the pressure inside the reservoir exceeds a specified level, the base plate is compressed downward against an upward biasing force thereon.  This opens bleed ducts and allows some of the fluid in the reservoir to flow back down to a chamber below the base plate.  Pilot holes are also provided to the piston for allowing small amounts of fluid to escape from the reservoir.  This allows the pump to idle at the start-up and hence to start the pump smoothly, as well as to prevent any overpressure conditions.
Patent CA-2136891-A1 (CA)
Title: Removal of swirl artifacts from celp based speech coders
Inventor: GANESAN KALYAN
IPC: G10L19/00
Filed: 1994-11-29
Abstract: The perception of speech processed by a CELP based coder, such as a VSELP coder, when operating in noisy background conditions is improved by removing swirl artifacts during silence periods. This is done by removing the low frequency components of the input signal when no speech is detected. A speech activity detector distinguishes between a periodic signal, like speech, and a non-periodic signal, like noise by using most of the VSELP coder internal parameters to determine the speech or non-speech conditions. To prevent the VSELP coder from determining pitches for non-periodic signals, a high pass filter is applied to the input signal to remove the pitch information for which the VSELP coder searches.
