Patent CA-2091589-A1 (CA)
Title: Reflective display and method of manufacture
Inventor: LONGOBARDI LAUWRENCE J
IPC: B44F1/04
Filed: 1991-11-07
Abstract: Displays are commonly used in the area of marketing. The problem with traditional displays is their two-dimentsional, flat appearance. A need exists for a more aesthetically pleasing display with a three-dimensional appearance. This need is fulfilled with a display having a transparent plastic substrate (12) and a colored image (18) formed on the substrate (12). The colored image (18) is formed on the substrate (12) by process printing a large number of small dots (26), colored red, yellow, and blue, in a predetermined pattern onto the substrate (12). The red, yellow and blue ink dots (26) are translucent to visible light. A reflective layer (30) is deposited against the ink layer (24) to reflect light which passes through the ink layer (24) and thereby give the image (18) formed by the ink layer (24) a shiny, metallic appearance. A  stratum (32) of opaque white ink is deposited between the reflective layer (30) and predetermined portions of the image (18) to block the passage of visible light from the predetermined portions to the reflective layer (30).

Abstract: La présente invention concerne une usine de traitement des fumiers liquides organiques frais ayant moins de dix (10) jours, fonctionnant en respectant les règles de l'hygiène et de l'environnement tout en produisant de l'énergie sous forme de gaz méthane, un produit chimique secondaire sous forme de gaz carbonique et de l'engrais organique ou en combustible. Dans la présente invention afin de générer le maximum de gaz méthane, la fermentation anaérobique produisant le gaz biologique est réalisée par les bactéries mésophiles anaérobiques opérant dans des conditions optimales à la température de quarante (40) degrés centigrades + 15% et cette fermentation se déroule principalement dans une cuve étanche de fermentation appelée digesteur-accélérateur primaire comprenant au-dessus de la zone de fermentation des surfaces fixes de ruissellement horizontales ou verticales où prolifèrent des colonies microbiennes. Tandis que la post-fermentation et la décantation des boues organiques digérées se produisent dans une deuxième cuve étanche appelée digesteur secondaire. Afin d'être conforme aux normes de l'environnement, l'eau résiduaire est traitée dans un décanteur floculateur avant son rejet à l'extérieur de l'usine ou son utilisation par recirculation.

Patent CA-2103232-A1 (CA)
Inventor: FEIT SUSAN
IPC: H04M3/42
Filed: 1993-11-16
Abstract: The drawbacks to administering a sequence of locations to which calls placed to a subscriber's personal telephone number may be routed for personal communication service are overcome by a) storing pre-defined mnemonic audible tags for association with telephone numbers prior to any interactions with the subscriber, b) offering the subscriber a choice of the pre-defined mnemonic audible tags by speaking them to him, c) receiving an indication of the mnemonic audibletag selected by the subscriber, d) receiving signals indicating a telephone number supplied by the subscriber; and e) storing the received telephone number information in association with the selected mnemonic audible tag. The mnemonic audible tagsare then used in place of their respective associated telephone numbers in administering the sequence of locations. A mnemonic audible tag is not simply anordering designation -- such as 1, 2, 3, ..., N; first number, second number, third number, ..., Nth number; A, B, C, ... --but instead is a meaningful word indicative of the actual location, person, or service, e.g., "office", "neighbor" or "AT&T voicemail", to which a call to the personal telephone number is to be completed.Advantageously, administering a sequence of locations is accomplished by simply manipulating friendly, meaningful, easy to understand terms rather than cumbersome, meaningless, telephone numbers or codes.

Title: Storage and transportation trunk for lighting equipment
Inventor: BORNHORST JAMES M
IPC: A45C5/14
Filed: 1993-08-10
Abstract: ABSTRACT A storage trunk for storing and transporting lighting equipment is constructed using a rotationally molded cross linked polyethylene plastic. The storage trunk is comprised of an enclosure body and a separately removable lid. The lid may be secured to the enclosure body by means of a plurality of latches. The interior of the enclosure body may be molded as a generally open rectangular region or may include molded features for receiving and supporting specific lighting instruments within its interior. The hollow walls of the molded enclosure body are filled with polyurethane foam for reinforcing the walls and damping their movement. A perforated metal stiffening frame is molded into the base of the enclosure body during the molding process for added strength. The underside of the enclosure body provides a plurality of casters for easy movement. The storage trunk features a unitized, seamless construction having no fasteners or external reinforcements to leak, snag other objects, or fall off. Various molded recesses, protrusions and surfaces in the storage trunk serve to enhance the functionality, strength and durability of the plastic storage trunk. Lateral bearing surfaces that protrude from the storage trunk minimize the wear on the exterior surfaces of the trunk by ensuring that the entire surface of the trunk does not contact adjacent surfaces. The storage trunk is constructed with convoluted end surfaces having protrusions and recesses that allow adjacent surfaces to interlock when positioned end to end.

Abstract: A square saw tooth having four cutting edges of the type which is rotatable about its axis on a saw disc to present a fresh cutting edge when the radially outermost edge wears out has carbide wear plates covering the high wear areas of its attack face and providing its cutting edges. A wear plate is provided at each corner of the attack face, and each wear plate has a flat rear surface for attachment to the tooth body and a front surface of a complex shape, having plateau surface areas at the corners, where the plates are thicker, and curved surfaces which recede from the plateau areas toward the interior of the attack face, so that the plate recedes in thickness away from the plateau area. This construction helps provide more uniform wear over the surfaces and edges of the attack face for a more efficient consumption of the wear plates.

IPC: B23K26/02
Filed: 1992-12-17
Abstract: A system and method removes material from a structure, by: (a) generating a light beam (12, 549) from a suitable source (10, 512);  (b) irradiating the surface material (18, 20) of a structure (14) with the light beam having an intensity sufficient to ablate the surface material and to cause the surface material to generate spectral emission signals (17) having intensities; (c) scanning the structure with the light beam at a scan speed; (d) monitoring the spectral emissions (17) to detect a selected one of the spectral emission signals having a selected wavelength and generating an electronic output signal (29a) representative of the intensity of a selected one of the spectral emission signals in response to detecting the selected one of the spectral emission signals;  (e) determining an updated scan speed functionally related to the electronic output signal; and (f) directing the scan speed to be equal to the updated scan speed. A second embodiment determines the updated scan speed based on the intensity of sepctral emission signals (17) detected during predetermined intervals while the structure is illuminated by a pulsed light source (512), such as a flashlamp. A third embodiment determines an updated scan speed based on the intensity of spectral emission signals resulting from a laser pulse irradiating the structure when the output of the light beam is approximately at a minium.
