Abstract: Dans la production d'emballages alimentaires aseptiques, il est habituel de contrôler et de vérifier la qualité du produit ou du récipient lui-même en retirant un certain nombre de récipients de la production pour les ouvrir, processus au cours duquel on peut procéder au contrôle de la qualité soit manuellement, soit à l'aide de procédés de contrôle de qualité connus, par exemple électriques. Ce contrôle est donc du type qu'on appelle destructif, c'est-à-dire que les emballages sélectionnés pour le contrôle des échantillons et leur contenu perdent leur valeur commerciale. L'invention concerne un procédé de contrôle de la qualité, ainsi que des emballages ou des ébauches d'emballage préparés à cet effet, qui comportent un ou plusieurs pôles (12) pouvant être reliés à un appareil électrique (24) de contrôle de la qualité. Le produit contenu dans l'emballage (20) étant ainsi directement ou indirectement accessible du point de vue électrique, sa qualité et l'étanchéité de son emballage (1) peuvent être déterminées d'une manière rationnelle et partiellement automatisée. Ceci est particulièrement important pour la production d'emballages aseptiques destinés, par exemple, à des potages prêts à l'emploi, traités thermiquement, ou à des aliments similaires.

Title: Grinding rod chemistry and method of heat treatment to enhance wearability
Inventor: PUGH ROBERT WILLIAM
IPC: B02C17/20
Filed: 1998-06-02
Abstract: A grinding rod chemistry enhances wearability and durability of a steel rod and comprises levels of carbon to achieve a surface hardness in excess of 55 Rockwell C and levels of chromium which achieve significant depth in the formed outer martensite shell. The grinding rod has a core greater than 99% pearlite with a hardness less than 45 Rockwell C and the end portions of the rod are soft and have a hardness less than 35 Rockwell C. The steel bar of the selected chemistry is treated by reheating to above its austenitising temperature, transferring with minimal cooling to an open tubular quench vessel while securing the bar in the vessel to minimize bar warping, introducing quench water into the inlet end of the vessel and passing the liquid through the vessel to ensure uniform heat removal. The outer martensite shell is tempered by allowing the bar to soak back after quenching. The bar end portions are reheated in a furnace to elevate the end portions above the austenitising temperature and air cooling each end portion to provide the engineered end portion hardness of less than 35 Rockwell C.

Filed: 1996-12-04
Abstract: The musical work is represented on a digital medium in the form of a database (150) comprising a plurality of fixed musical sequences, and a template comprising a plurality of sequence positions. Each sequence position may represent one track of a musical arrangement, such as the performance of one instrumental group, or a musical solo. The various tracks are intended to be played simultaneously, in parallel. In fixed-addition, some of the sequence positions may represent length, partial segments of a single track that are intended to be played serially. Using a menu-driven, graphical interface, a user interactively selects a plurality of the fixed musical sequences, as desired, and allocates the selected sequences among the various fixed sequence positions specified by the template. The musical sequences are then combined in accordance with the user's selections, thus creating a new arrangement of the musical work.      In this way, users of varying levels of sophistication can be given a musically structured framework for interactively constructing new arrangements of recorded musical works.

Title: Process and apparatus for removing odor from animal confinement buildings
Inventor: POTEAT JERE
IPC: B01D45/10
Filed: 1998-12-16
Abstract: Apparatus and methods for removing odor from the air exhaust of animal confinement buildings are described. One embodiment of the apparatus includes a plenum housing attached to an existing exhaust fan on an animal confinement building. The plenum housing has an entrance and an exit, and houses a baffle having a roughened surface. Water is delivered to the baffle surface by spray headers which are configured to spray water from a top edge of the baffle. A water curtain is generated by spray nozzles at the plenum housing exit. A trough is configured to collect a water effluent from a bottom edge of the baffle. In use and according to the methods described, an air stream consisting of exhaust air from an animal confinement building is directed toward the water- flooded baffle surface. Odor particles in the air stream impinge on the baffle surface and are adsorbed by the water. The air stream continues to flow past the baffle surface and through the water screen at the plenum housing exit. Additional odor particles and water soluble gases are absorbed and adsorbed by the water screen. Droplets from the water screen fall to the baffle surface and are collected with the effluent. The effluent is drained away directly to a lagoon or to a primary waste water treatment facility for treatment to remove odor particles and gasses.

Title: Method for providing enhanced h.321-based multimedia conferencing services over the atm wide area network
Inventor: ROY RADHIKA R
IPC: H04L12/56
Filed: 1998-03-19
Abstract: An enhanced H.321-based multipoint, multimedia conferencing service is provided over the ATM WAN interconnecting geographically dispersed H.321 terminals with a centralized H.321 MCU located within the WAN. The performance of H.321 multimedia conferencing services over the ATM WAN is improved by providing a modified WAN-based H.321 MCU which de-jiterizes cell delay variation and detects cell losses. The MCU supplies the reference clock signal that will be used by all communicating entities for synchronization, smoothes ATM cell delay variation and creates dummy bits in the case of cell losses, to create a more accurate H.221 frame. The information about the dummy bits of the H.221 frame is sent to upper layer entities to facilitate compensation at the appropriate positions of the cell/bit losses for audio and/or video traffic. The higher layer audio and video entities compensate for audio and/or video cell/bit losses with the information provided by the lower entities. In addition, intramedia and intermedia synchronization are provided for both audio and video traffic. Finally, transport protocol suits are incorporated on the top of H.221 layer to recover data cell losses or errors. Customer premises-based H.321 terminals may also employ the modified H.321 services noted above in the H.321 MCU to compensate for audio and/or video cell losses or errors for improvement of performance.

Patent CA-2275685-A1 (CA)
Inventor: HILL CHARLES C
IPC: B01D53/04
Filed: 1996-12-20
Abstract: A rotary valve (21) at the inlets of a plurality of columns (18) cyclically selects first columns on a cyclic basis to receive compressed air, adsorb nitrogen and other components in the compressed air and pass oxygen and argon to a user (e.g. patient), second columns to desorb the adsorbed components in such columns and third columns to equalize pressures where the first columns change progressively to the second columns and vice-versa. A compressor (13) having adjustable characteristics and regulated in an open or closed loop introduces the compressed air through the valve to the first columns to provide an adjustable air flow for obtaining a prescribed oxygen flow to the user. An indication (88) may be provided when the compressor characteristics regulated for obtaining the prescribed oxygen flow rate are outside particular limits. The valve may have a variable speed related to the compressor flow variations to regulate the air pressure in the columns in accordance with the air flow rate into the columns. A variable orifice (27) in a valve in each column outlet becomes constricted with decrease in the oxygen flow rate in each column, thereby further regulating the oxygen pressure in such column. A porous plug in a closed chamber receiving the desorbed pressurized components releases such components slowly, without pulsatile noise, to the atmosphere. The equipment accordingly produces the desired oxygen flow rate with minimal power consumption, minimal noise and optimal efficiency, reliability and life span. The equipment may be designed to pass other components than oxygen.
