IPC: A23L3/3418
Filed: 1996-02-02
Abstract: Procédé et appareil pour créer un écoulement de fluide autour de fruits et légumes frais stockés dans des conteneurs dont les parois latérales sont percées de trous. Une rangée composée de plusieurs conteneurs de ce type est placée le long d'un mur et écartée de celui-ci par une certaine distance, de manière à créer un espace intermédiaire entre le mur et la rangée. On gonfle au moins un sac qui s'étend, dans ledit espace intermédiaire, le long de l'un au moins des bords de cette rangée, en injectant un fluide dans le sac, de sorte que ce sac entre en contact étanche avec le mur d'un côté et avec la rangée de l'autre côté. Le fluide alimentant le sac s'écoule par des ouvertures de sortie ménagées dans le sac, et pénètre dans l'espace intermédiaire pour y créer une pression élevée. Ensuite, le fluide s'écoule depuis l'espace intermédiaire en passant par les trous percés dans les parois latérales du conteneur, et s'écoule autour des fruits et légumes frais. Ce système trouve application notamment dans les locaux de stockage dans lesquels on peut disposer, le long des murs latéraux opposés, des rangées de conteneurs renfermant des fruits et légumes frais, et il est avantageux notamment lorsque le sac gonflable à l'état gonflé crée un contact étanche dans une zone de contact annulaire entourant la totalité de l'espace intermédiaire.

Title: A toilet blockage remover
Inventor: KANG KYUNG TAEK
IPC: E03D9/00
Filed: 1996-10-03
Abstract: A toilet blockage remover (17) is provided in three selected versions. The first version (21) includes a toilet bowl cover (19) attached to a soft pad (23). The second version (43) includes a pump (47) attached to a soft pad (45) wherein the soft pad (45) has a cutout (49) forming a thru-hole (51). The third version (61) includes a toilet bowl cover (19), a soft pad (23) attached to the toilet bowl cover (19), and the pump (47) attached to the toilet bowl cover (19).

Title: Color sorting machine for cereal grain or the like having dust collecting device
Inventor: ITO TAKAFUMI
IPC: B07C5/342
Filed: 1997-12-15
Abstract: A color sorting machine sorts particles of different colors from raw material such as cereal grains or the like.  The machine has a down chute descending towards a front side of the machine for letting raw material particles flow down linearly, a photoelectric detection device which subjects the raw material particles jumped out of the down chute to light and discriminates different-color particles in accordance with difference in reflected light, and a nozzle device which injects air to and blows off the different-color particles.  The injection nozzle device is situated on the rear side of the machine with respect to a coming-down locus of raw material particles from the down chute and close to the coming-down locus.  The sorting machine further comprises a dust collecting device which is situated on the front side of the machine with respect to the coming-down locus of the raw material.  The dust collecting device has a dust collection opening which is substantially opposite to the injection nozzle device with the coming-down locus interposed therebetween, sucks in and discharges dust scattered from the raw material.  The color sorting machine is highly precise in sorting different-color particles and facilitates cleaning of the dust collecting device.

Title: Pre-compression nitrox in-line blender
Inventor: COWELL ROSS A
IPC: B01F23/10
Filed: 1998-01-07
Abstract: A pre-compression nitrox in-line blender for homogeneous mixing of oxygen and nitrogen to reduce nitrogen levels in compressed breathable air includes an oxygen diffuser drawing ambient atmospheric air through an air intake into the diffuser. A  downstream end of the difuser communicates with an upstream end of an in-line turbulent mixer. The turbulent mixer is mounted within a sealed conduit for generally homogeneous mixing of oxygen from a high pressure source with the ambient atmospheric air so as to form homogeneous nitrox gas as the oxygen and the ambient atmospheric air pass through the turbulent mixer along the sealed gas conduit.

Title: Catheter
Inventor: ALVAREZ DE TOLEDO FERNANDO
IPC: A61M25/00
Filed: 1996-08-05
Abstract: The present invention relates to catheters for use with subcutaneous access ports for continuous or intermittent infusion therapy. These catheters utilize a pretension, helical coil (8) which is incorporated into a flexible cannulated portion (7). This feature allows the flexible cannula to be bent without kinking under normal use. This flexibility provides a great deal of comfort to the patient. These catheters also incorporate a puncture needle (2) which is positioned axially down the length of the catheter such that the sharp point at the distal end of the needle entends the distal end of the catheter. This combination of a pretension, flexible catheter and a puncture needle achieves a stiffness sufficient to penetrate the tough, self-sealing septum used in subcutaneous access ports, yet, once the puncture needle is removed the patient is left with a comfortable alternative to commonly used hypodermic needles. The present invention also relates to improved transcutaneous infusion systems which utilize these catheters.

Patent CA-2234311-A1 (CA)
Inventor: ILAGAN ARTEMIO
IPC: F21V17/12
Filed: 1998-04-02
Abstract: An attachment configuration for securing a circular light fixture cover to a correspondingly configured light fixture base, includes an outwardly extending helical flange around the base of the cover and a mating helical channel within the light fixture base.      Preferably, the flange and channel each form only a single pitch and extend around their respective components only 360 degrees, thereby allowing the fixture cover to be removed from or installed upon the fixture base with only a single turn. A stop may be provided in the assembly to prevent overtightening of the cover to the fixture base, and alignment markings may be provided to indicate the initial engagement point and fully engaged point of the cover relative to the base. The flange and mating channel may be provided on either of the components, and may be oriented inwardly or outwardly as desired, so long as the corresponding cover and fixture base have complementary and mating configurations. The system may be used to secure light fixture covers having convex shapes to mating fixtures, and may also be applied to flat covers for flush mounted fixtures.      The present attachment system provides a tight fit between the cover and fixture base, thus precluding entry of insects or other small animals into the interior of the assembly. The attachment system is devoid of screws, clips, or any other components, and requires no tools or other equipment to install and remove the light cover to and from its corresponding light fixture base.
