Title: Method and apparatus for detecting mercury
Inventor: SCHAEDLICH FRANK H
IPC: G01N1/00
Filed: 1994-03-15
Granted: 1999-08-10
Abstract: Mercury Detection Method and Apparatus utilizes cartridges including gold for adsorbing mercury as an amalgam. The adsorbed mercury is desorbed by heating and passed through a Cold Vapour Atomic Fluorescence Spectrophotoreeter. Each cartridge is flushed with an inert gas, so that air and contaminants are never passed directly through the detector, so only inert gas passes through it.      To further prevent adsorption of contaminants, the cartridges are maintained at a minimum temperature, above ambient temperature and below 100°C. To enable unattended calibration, a permeation source is provided having a permeation chamber and a value assembly, including 3 separate valves, to ensure than in an off state mercury vapour cannot leak to the cartridges. To ensure an efficient use of the inert gas, its flow can be adjusted between 3 different levels, for flushing, desorption of mercury, and an idle state to maintain the apparatus purged air.

Title: Method and apparatus for telephone prize opportunities
Inventor: KASDAY LEONARD RALPH
IPC: G06F19/00
Filed: 1994-08-18
Granted: 1998-09-22
Abstract: A telephone network is modified so that callers making telephone calls can engage in a game of chance to win a prize without having had to specially dial the game processor, i.e., the telephone numbers of the telephone calls are independent of the game processor. In one embodiment of the invention, the game processor is part of the switch that processes calls through a telecommunications network. Upon conclusion of the game, the caller is supplied with an indication as to whether or not he is a winner and will receive a prize. The determination that acaller is a winner need be made only if the call was successfully completed, that is, routed to a destination at which the call is answered. Advantageously, a) games of chance are attractive to people, especially when it costs nothing to enter, b) the determination that a caller is a winner can be immediately conveyed to him, and c) by proper selection of the odds of winning and the value of prizes, the game can be arranged so that its cost to a telecommunications carrier is less than that carrier's present discounting program.

Patent CA-2143658-C (CA)

IPC: B07B1/38
Filed: 1993-10-05

Abstract: The screening efficiency of a gyratory screening machine (10), of the type having a moving base (14), is significantly in-creased by mounting to the base a spring/mass system (66, 64) which is tuned so that operation of the machine drive (19) pro-duces amplified movement of the mass (64) along at least one of two perpendicular axes on which the base moves. Movement of the mass (64) reduces the net force on the base along the axis on which the mass oscillates. The reaction force of the machine drive (19) on the base along the other of the two perpendicular axes may be offset by a rotary counterbalance (62) operated by the drive. Movement of the base relative to the ground (15) is thereby reduced, and movement of the screen deck relative to ground (15) is increased. This both increases the effectiveness of the screening motion and decreases the total reaction force transmitted through the base.

Title: Shaped semi-solid or solid dishwashing detergent
Inventor: ZINT DAVID ROBERT
IPC: C11D1/72
Filed: 1995-04-24
Granted: 1999-03-30
Abstract: The present invention provides a firm, mild, good performing, low-smear semi-solid or solid dishwashing product. The rheology of the dishwashing product is such that structural elements have been separated from functional elements to obtain best structure properties and in-use properties. By using an interlocking mesh of carboxylic acid and/or neutralized carboxylic acid fibers and/or platelets to provide a support structure, the semi-solid or solid dishwashing product can be loaded with superior performing  dishcare materials (e.g., mild surfactants) and appearance enhancers without dependence on surfactant-water phase behavior to provide the support structure. As a result, the present dishwashing product is milder than semi-solid dishwashing products currently on the market. The support structure of the present product, and preferably the use of hygroscopic surfactants, provide a product with lower smear than current gel dishwashing products.

Abstract: A method is claimed for the regulation of continuous casting between rolls. During casting the separation force (RSF) of the rolls is measured and the position of the bearings of at least one of the rolls is acted on in order to increase or diminish the inter-axial distance between the rolls. In order to maintain this separation force essentially constant a table of force values ( DELTA RSF) is predefined, framing a desired nominal force (RSFo) and position of the bearings are acted on more sharply when the measured force is outside the table of values than when it is within the extreme values in the table.

Abstract: A so-called "ELAN contronect network" is employed to interconnect sub-ELANs to form an ELAN. More specifically, the "ELAN contronect network" is a separate network for interconnecting the servers of the sub-ELANs, where a sub-ELAN is a part of an ELAN having its own LES and BUS that may also be configured as a stand-alone ELAN.  Each of the sub-ELANs is connected to the ELAN contronect network via a point-to-point connection-oriented connection, e. g., an asynchronous transfer mode (ATM) connection and the ELAN contronect network is configured to present itself to each of the servers of the sub-ELANs as clients thereof. In a particular embodiment of the invention, the ELAN contronect network includes an address server, a broadcast/route server, a configuration server, multimedia servers, and at least one LAN hub interconnected over a high-speed backbone. The address server contains an address data base for performing address resolution between the at least two addresses of each ELAN end-point in response to requests for such translations. The broadcast/route server receives data packets for broadcast to a different sub-ELAN from which the packets originated and broadcasts the received data packets to at least one other sub-ELAN. The broadcast/route server also recognizes that a packet which is a broadcast packet at layer 2 is actually a request for an address resolution at layer 3.If so, the broadcast/route server collaborates with the address server to perform the necessary address resolution and insures that a response is sent only to the client originating the request.

Title: Rear suspension system for a land vehicle
Inventor: BOIVIN DENIS
IPC: B62D55/108
Filed: 1996-11-22
Granted: 2005-01-25
Abstract: A suspension assembly for mounting an endless track to a chassis of a snowmobile, the suspension assembly having a pair of pivoting arms centrally mounted to the slide members, or rails, and a weight transfer dynamic compensator capable of compensating for the weight transfer of the snowmobile when the track is pulling on the chassis. The weight transfer dynamic compensator prevents the chassis from rotating excessively with respect to the slide rails during rapid acceleration. Such a rotation of the chassis is detrimental to rider comfort and stability. The suspension assembly is coupled such the rails remain somewhat parallel to the chassis when encountering a bump at either the front of the rails or at the rear of the rails, also enhancing rider comfort and stability. The suspension assembly is coupled by virtue of a limited-translation slide bar at the rear of the suspension assembly and a tension-only member, or pulling belt, located at the front of the suspension assembly. The suspersion assembly having the weight transfer dynamic compensator improves the cornering of the snowmobile by ensuring that there is ample weight on the front skis, especially when accelerating out of a turn.
