Patent CA-2295886-A1 (CA)
Inventor: MUSCARA DOMINIC
IPC: B65B43/52
Filed: 2000-01-13
Abstract: Method and apparatus for conveying a plurality of containers to a filling station for supplying the containers with paints or coatings. The conveyor is periodically driven to the filling station by a rotary actuator including a plurality of air motors which drive a pinion which in turn is connected to the drive shaft of the conveyor for moving the conveyor in one direction to the filling station. The conveyor drive shaft operates a cam which controls a valve in an air supply line for actuating a diverter valve which controls the supply of air to the rotary actuator. The conveyor is stopped when the cam closes the valve, this occurring when the containers reach the filling station. After the containers are filled, a solenoid is actuated through means of a timer to open a second air supply valve in a second air supply line which is used to actuate the diverter valve to drive the rotary actuator a distance sufficient to move this cam for opening the first supply line whereupon the conveyer continues to be driven to remove the filled containers from the processing station and to bring new containers to be filled to the processing station. The valve controlling the second air supply line is closed through a timing mechanism which in turn is controlled by a computer-controlled signal occurring when the containers are filled.

Abstract: A method for integration of the institutional supply chain for medical products utilizing a nested bill of materials on a care event level of a clinical pathway (42), for one or more medical procedures (34, 36, 38, 40). The medical supplies appropriate for use in a care event are expressed as a bill of materials. Each item of medical supply is assigned a unique identifier which includes at least identification of the items itself, identification of the supplier of the items, and identification of the care event with which the item is to be used. Portions of the supplies are provided by multiple vendors (30, 32) to a unitized container sequencing centre where the supplies are bundled by care events and packaged into a unitized container. This container is then shipped to a customer or distributor for further shipment to a customer.

Abstract: A decorative cover for cans and in particular, spray cans, which may be aerosol spray cans or non-aerosol spray cans. The decorative cover is wrapped around the spray can so that it will be attractive and not unsightly. The decorative cover is made of fabric material and usually consists of a front layer of fabric material, a back layer of fabric material, and an intermediate member which may be made of foam or other type of material to give the fabric some thickness. Adjacent one edge on the front layer is a closure fastener and adjacent a mirror image edge on the back layer is a complementary closure fastener. The cover wraps around the can so that the closure fasteners come in contact with each other to close the fabric cover around the can. Between the layers is a piece of foam material to give the overall cover some thickness so that it is easier to feel.

Title: Multi-layer screen for the wet area of a paper machine and product manufactured using the same
Inventor: LAMB HANS-JUERGEN
IPC: D21F1/10
Filed: 1998-07-21
Abstract: The invention relates to a multi-layer screen (10, 11) for the wet area of a paper machine and to a tissue paper produced using the same. The inventive screen consists of threads, preferably woven threads, forming at least two layers. These layers are joined to each other by additional threads (14) which are interlaced with the layers. Together with the threads which make up the layers, the additional threads (14) form constricted points (16), said constricted points being spread across the length and breadth of the screen. A  significantly less quantity of water can pass through these points than through the areas adjacent thereto. Arranged in special sequences, the additional threads are a means of influencing the drainage of water through the screen at the constricted points for producing tissue paper with alternating areas of high and low GSM substance. The invention therefore provides a simple means of producing a tissue paper with a flexible, thin, non-homogeneous, net-like structure.

Title: Vacuum cleaner
Inventor: MITCHELL CARL
IPC: A47L9/12
Filed: 2000-05-23
Abstract: The vacuum cleaner includes a hollow canister, one end of which is closed by a removable cap to permit removal of debris from within the interior. The canister is separated into two compartments, one defined by the first end and a hollow rigid conical filter disposed in the interior. The filter has a base adjacent to the inner wall throughout its extent and tapers toward the second end of the canister. The filter further has openings too small to allow debris such as cigarette and cigar butts, excrement of animals and birds and the like to pass therethrough but large enough to allow smaller debris to pass .      A second compartment is defined by the filter and a relatively flat filter having openings smaller than that of the conical filter. Both filters extend across the interior such that all air which travels through the interior must pass through the filters. An intake hose admits debris-laden air into the first compartment and an exhaust discharges air from the second compartment. Suction means causes air to flow from the inlet of the tube, through the interior and to exit through the exhaust.

Title: Therapeutic and diagnostic methods dependent on cyp2a enzymes
Inventor: SELLERS EDWARD M
IPC: A61K31/465
Filed: 1998-12-01
Abstract: A method of regulating the activity of human cytochrome P450 isozyme CYP2A6 to control nicotine metabolism or decrease the production of carcinogens from procarcinogens, such as those present in tobacco smoke, in an individual by selectively inhibiting CYP2A6. Various prophylactic (i.e., prevention and treatment) compositions and methods are also described, including an improved oral nicotine composition and method comprising the use of nicotine together with an inhibitor of the CYP2A6 enzyme. Furthermore, it has been discovered that the presence in an individual of a mutant allele of human cytochrome P450 enzyme CYP2A6 (referred to throughout this specification as "CYP2A6" for brevity) is predictive of an individual who: (i) has a decreased risk of becoming a smoker, (ii) will smoke less if he/she becomes dependent, and/or (iii) may be at relatively lower risk for cancer due to both decreased smoke exposure and decreased CYP2A6-mediated activation of tobacco smoke and other procarcinogenic substrates. This invention provides diagnostic methods for predicting tobacco dependence risk and risk for cancers related to CYP2A6 substrates in an individual by analysing for the presence of a mutant genotype for human cytochrome P450 enzyme CYP2A6 in an individual, ranging from gene duplication (multiple copies of CYP2A6) to single or even no copies due to null alleles or gene deletion.

Title: Electrical connector system with cross-talk compensation
Inventor: WININGS CLIFFORD L
IPC: H01R13/6466
Filed: 2000-07-10
Abstract: An electrical connector system with an electrical connector having signal contacts exhibiting unwanted cross-talk; and a circuit substrate engaging the connector. The substrate has a plurality of layers and at least first, second and third traces, each corresponding to a respective signal contact. The first trace includes: a first portion on at least one of the layers and adjacent a portion of the second trace in order to produce a first compensating cross-talk; a second portion on at least another of the plurality of layers and adjacent a portion of the third trace in order to produce a second compensating cross-talk. The substrate could also comprise a board having a first layer, a second layer, a plurality of inner layers between said first and second layers, and a ground plane on at least a lower surface of said board. The inner layers have at least first, second and third traces, with the first trace having portions adjacent the second and third traces in order to produce a first and a second compensating cross-talk, respectively. The system reduces unwanted cross-talk by introducing a first compensating cross-talk by inductively and capacitively coupling a first conductor and a second conductor adjacent the first conductor; and introducing a second compensating cross-talk by capacitively coupling the first conductor and a third conductor once removed from the first conductor. The compensating cross-talks offset the unwanted cross-talk to produce an acceptable cross--talk.
