Patent CA-2197002-A1 (CA)
Inventor: LENHART RONALD A
IPC: B65G51/03
Filed: 1995-11-22
Abstract: A damperless, controlled speed, coverless, isometric air conveyor (10) and method for conveying lightweight containers (16) en masse or individually at a controlled speed is provided. A first set of louvers (14) extend through a conveyor surface from a common plenum at an incline to a conveying surface so that the air passing through the louvers (14) has a downstream force vector of a first magnitude. A second set of louvers (14) extend through the conveyor surface from the common plenum at an incline to the conveyor surface so that the air passing through the louvers has an upstream force vector of a second magnitude which is less than the first magnitude thereby creating a vector force differential in the downstream direction at any given location under the bottom of each container to cause movement of the containers (16) in the downstream direction. An outboard row (30) of louvers along each edge of the conveying surface may be angled in the inboard direction to urge the mass of containers toward the center of the conveying surface into a tight pack and to provide a downstream force to assist in moving the mass in the downstream direction and to cause a cross flow of air creating an air barrier through which a single or sparse flow of containers must move, thereby limiting the speed of the single or sparse containers. The inboard cross flow of air also creates low pressure at the trailing edge of the single or sparse containers to maintain them in an upright position.

Title: Methodes et electrodes de decharge pour production de plasmas a une pression d'une atmosphere et materiaux ainsi traites
Inventor: SPENCE PAUL D
IPC: B01J19/08
Filed: 1996-06-19
Abstract: La présente invention concerne deux procédés et les types correspondants d'électrodes pour la génération d'un plasma sous environ ou exactement une atmosphère. Ces procédés permettent de traiter correctement en un temps réduit différents produits bandes, films et objets tridimensionnels. Le premier procédé utilise une impulsion répétitive à tension asymétrique pour générer une décharge de plasma entre deux électrodes. L'impulsion de tension asymétrique permet de générer une décharge dans laquelle un substrat peut être exposé essentiellement à un plasma de nature soit positive, soit négative, suivant la polarité de tension utilisée. Un second procédé met en oeuvre la capacité d'entrefer d'une paire d'électrodes et un inducteur externe dans un circuit shunt pour constituer un circuit LC résonant. Ce circuit est piloté par une source de radiofréquences haute puissance fonctionnant entre 1 et 30 MHz générant ainsi une décharge uniforme entre la paire d'électrodes. Avec les deux procédés, on utilise des surfaces de décharge à température stabilisée ainsi qu'une alimentation en gaz à régulation de température, d'humidité et de débit. Le débitdu gaz est normalement suffisant pour créer une zone d'écoulement présentant une turbulence au niveau de la région de décharge où les matériaux sont traités. Les paires d'électrodes, que mettent en oeuvre ces procédés, sont constituées d'une électrode à face métallique et d'une électrode recouverte d'un diélectrique. Une électrode ou les deux électrodes présentent une série d'orifices traversant la face d'électrode de façon à permettre l'alimentation en gaz. Le second procédé décrit ci-dessus peut également fonctionner avec une paire d'électrodes à face métallique, mais dans des conditions de fonctionnement plus restreintes.

Title: Timed photocell switch circuit
Inventor: SEARS LAWRENCE
IPC: H05B37/02
Filed: 1997-05-15
Abstract: A timed photocell switching circuit is disclosed which senses a light-to-dark transition and applies power to a lamp load for a preset period of time.  After the preset period has expired the timed photocell circuit turns the lamp load off for the remainder of the night until a dark-to-light transition resets the circuit after which it can be triggered for another timing cycle.  Once the light-to-dark transition triggers the timing cycle the ambient light level cannot disrupt the circuit.  In addition, the circuit can be reset regardless of its timing position by momentarily cycling power to the circuit.

Patent CA-2213544-A1 (CA)
Title: Elongated drill with replaceable cutting inserts
Inventor: SHALLENBERGER FRED T
IPC: B23B51/04
Filed: 1997-08-21
Abstract: A metal cutting drill with replaceable cutting inserts and a length to diameter ratio of four to one or more.  Two cutting inserts are positioned in exactly opposed diametric positions, and engage the workpiece in a substantially identical manner to precisely balance -the radial forces resulting from drill axially advancing though a workpiece.  Through the use of dual cutting inserts, the drill cuts the full circumference of a bore with each one-half revolution and therefore achieves the a faster axial feed rate.  By virtue of the inserts being triangular, the curved corners on the cutting edges of the two inserts may be positioned relatively close together and yet sufficient space is left between the inserts to enable the drill shank between the inserts to be relatively thick and strong even at increased length to diameter ratios.  Through the provision of a length to diameter ratio greater than four to one, the bores which the drill is able to produce are substantially deeper at any given diameter than those achievable by prior art indexable drills.
