Patent CA-2261595-A1 (CA)
Title: Raccord de tuyaux segmente limitant les mauvais ajustements
Inventor: DOLE DOUGLAS R
IPC: F16L21/06
Filed: 1997-07-07
Abstract: Cette invention concerne des segments de raccords (12, 14) possédant des faces terminales inclinées (16a, 16b) et pourvus d'éléments d'arrêt (30, 32) au niveau de leurs extrémités respectives qui permettent d'éviter un mauvais ajustement des segments de raccords (12, 14) au cours de leur assemblage sur les extrémités adjacentes de tuyaux ou d'accessoires de canalisation. L'élément d'arrêt (30, 32) est écrasé au cours du serrage final du raccord de manière à n'autoriser ultérieurement qu'un mouvement latéral limité des extrémités du segment de raccord (12, 14), ce qui assure la formation d'un raccord véritablement rigide et supprime le risque d'inclinaison des axes des tuyaux ou des accessoires de canalisation respectifs.

Patent CA-2263806-A1 (CA)
Title: Phosphine fumigation method and apparatus
Inventor: WINKS ROBERT GORDON
IPC: A23K3/00
Filed: 1990-06-25
Abstract: Fumigation  of  grain  in  a  storage  facility  having  a plurality of grain silos (13) is effected from a single source (10) of a gaseous fumigant.  The single source of gaseous fumigant is connected to a gas supply duct (11), to which gas inlet ports of the silos are also connected.  The connection between each gas inlet port and the duct is provided with a respective valve (14) and a respective orifice plate (15), which is adjusted so that the pressure drop  across  the  orifice  plate  into  the  silo  is substantially greater than the pressure drop across any other component between the gas source and the silo.  With this arrangement, the flow rate of gaseous fumigant through the grain-containing silos in the facility suffers only a minor perturbation when a valve between the duct and a silo is opened or closed.   This minor perturbation can be readily compensated by maintaining the gas pressure in the duct at a constant value.

At least one passageway is defined within the unit, the passageway being sufficiently inclined so that the supply of objects flows through the unit solely under the force of gravity. Diverting means disposed along the passageway selectively divert objects from the passageway toward and through an associated secondary opening, located adjacent the passageway. A dividing chute associated with each secondary opening is provided to direct the diverted objects to one of a plurality of different predefined locations.
Patent CA-2266335-A1 (CA)
Inventor: ROTHERING LAWRENCE P
IPC: B25B21/00
Filed: 1997-09-16
Abstract: A hydraulic pump assembly (10) for powering a hydraulic torque wrench (24) is air-powered and has hydro-pneumatic control circuitry (39) which continues operation of an air motor (18) which drives the hydraulic pump (16) for a postadvance period after an advance actuator (55) is deactuated. Operation of the pump (16) is continued for a period sufficient to retract a double-acting torque wrench (24), to permit subsequent advances of the wrench (24) within the post-advance period without restarting the pump (16) or to permit a single acting wrench to be moved from one fastener to the next within the postadvance period without restarting the pump (16). Operation of the pump (16) is terminated when the post-advance period expires if the advance actuator (55) is not reactuated, so as to conserve energy and avoid unnecessary heating of the hydraulic fluid.
Patent CA-2270212-A1 (CA)
Title: System for draining a liquid storage tank
Inventor: MARINHO ARTUR ROGERIO MONTEIRO
IPC: B01D17/025
Filed: 1997-09-18
Abstract: The present invention relates to a system which makes it possible to remove undesirable liquids, generally an aqueous phase, which precipitate to the bottom of tanks for storing liquid products. Use is made of a drainage device (30) which comprises a concave body (31), a seat (26), and an interface float (8) which has a plug portion (25). This interface float (8) is designed to sink into the product and to float on the aqueous phase. As the level of the aqueous phase drops, the plug portion (25) settles sealingly on the seat (26), halting the drainage operations since all the accumulated aqueous phase has already been drained off. The drainage system may be automatic or manual. In the former case, use is made of a sensor (12) for detecting the presence of an aqueous phase and commanding the process of opening a shut-off valve (11) and allowing drainage of the accumulated aqueous phase. In the manual case, an operator periodically checks for the presence of an aqueous phase inside de storage tank (1), through a port (28) for inspecting the level. If such a phase were to accumulate, he opens a manual shut-off valve (29) so as to allow all the accumulated aqueous phase to drain away.

Title: Automated lateral translation conveyor
Inventor: BONNET HENRI
IPC: B65G47/46
Filed: 1998-01-20
Abstract: An automated conveyor sortation and item discharge system (10) for sorting items (24) of varying sizes and weights to designated output destinations (16) along a conveyor (10). The system (10) utilizes a segmented slat (18) conveyor connected by flexible connectors (36). The flexible connectors (36) form a tooth (40) for driving the conveyor (10) by a sprocket (58). The flexible connectors (36) isolate adjacent slats, and the flexible teeth (40) isolate the slat (18) conveyor from the drive sprocket (58) for an enhanced reduction in noise levels. The system (10) may utilize a conventional belt (225) conveyor or rigid platforms (18) attached by flexible connectors (36). Removable ejection mechanisms (124) can be attached to the individual slats (18) of the slat conveyor (10) or to the belt of a belt conveyor (225). The ejection mechanisms (124) have self-contained drive (154) and actuation mechanisms (148) and may operate independently of the speed of the conveyor (10). The drive mechanism (300) for the ejection mechanism (220) may be located separately from the ejection mechanism (220) to drive the ejection mechanism (220) when the ejection mechanism (220) moves adjacent to a desired discharge destination (16). A programmable controller may be provided to control the conveyor (10) and the discharge of items (24) from the conveyor (10) by the ejection mechanisms (124, 220). The system is easy to repair and operates at high speeds at reduced noise levels.

Title: Synchronization of individual section machine operation to gob feed in a glassware forming system
Inventor: SHINABERRY DEREK
IPC: C03B7/14
Filed: 2000-02-04
Abstract: An individual section (IS) machine glassware forming system includes an individual section machine with a plurality of individual sections for receiving gobs of molten glass and forming the gobs into articles of glassware. A gob feeder presents gobs of molten glass, and a gob distributor feeds the gobs to the individual machine sections in sequence.  Operation of the machine sections is synchronized to operation of the glass feeder by generating a feeder index signal indicative of presentation of glass gobs at the glass feeder. An electronic machine timing circuit includes facility for electronically generating a machine index signal for synchronizing operation of the machine sections with respect to each other. Separation in real time between the feeder index signal and the machine index signal during system operation is determined and stored in units of time. Upon initialization of operation of the system after shutdown for any reason, this stored time is automatically retrieved, and timing of the machine index signal is automatically adjusted relative to the feeder index signal to equal this stored time.
