Patent CA-2272692-A1 (CA)
Inventor: CAHILL MICHAEL JOHN
IPC: B31B1/74
Filed: 1997-11-26
Abstract: A method is disclosed of forming a bag having a bottom seal from a web of sealable sheet material which is formed into a tube (12) by sealing opposite longitudinal edge portions of the sheet material one to another. The method comprises feeding the tube (12) in flattened form further along a feed path to a severing station (10), severing the flattened tube (12) in passage through the severing station (10) into individual flattened bag lengths (36) by passage between a rotary knife (26) and a counter blade (26'), feeding the individual flattened bag lengths (36) longitudinally along the feed path to a sealing station (11), and applying pressure, and possibly also heat, to opposite faces of an end portion of each flattened bag length (36) as it passes through the sealing station (11) by means of blocks (31) for a predetermined time which is longer than the period between severing that bag length (36) from the flattened tube (12) and severing the next bag length (36) from the flattened tube (12) while continuing to feed the flattened bag length (36) longitudinally along the feed path thereby to form a bottom seal (41) for the bag. Preferably the flattened tube (12) is formed with gussets (14, 15). The blocks (31) can be heated if the web is made of a heat sealable material. The heater bars (38, 39) for the gussets (14, 15) can be mounted on a different, more lightly spring loaded, mounting block from that for the heater bar (37) which forms the transverse bottom seal (41). By using rollers (24, 25) and making blocks (31) move slightly faster than the speed of the flattened tube (12) prior to severance of the bag length (36) it can be ensured that the bag lengths (36) are positively severed from the flattened tube (12) despite possible wear of, or damage to, the cutter blades (26, 26'). Registration of the printing on the web (12) so that the blocks (31) contact the web (12) in appropriate position to form the bottom seal (41) can be achieved, when the desired registration is disturbed, by temporarily varying the feed speed of the web (12) with respect to the speed of rotation of the rotary knife (26) so as to vary temporarily the lengths of the bag lengths (36) severed from the tube (12) until the desired registration is reestablished.

Title: Complex filtering/agc radio receiver architecture for low-if or zero-if
Inventor: BIRKETT A NEIL
IPC: H04B1/30
Filed: 1999-11-15
Abstract: A low power IF strip architecture suitable for Zero-IF (ZIF) or low-IF (LIF) radio receivers for filtering and amplifying a received signal. The apparatus includes a plurality of sequentially connected complex filter/amplifier stages. Each stage includes a complex filter having one or more poles and an automatic gain controlled amplifier (AGC). Each AGC may be feedback or feedforward with fixed minimum and maximum gains. Each stage further includes a control circuit that produces a gain control signal for controlling the amplifier gain within the fixed minimum and maximum gains as a function of a projected amplitude level. The received signal passes through multiple stages of filtering and controlled amplification to attenuate the interfering signal and amplify the desired signal. This is done at a restricted level in each stage such that the circuits in the stages operate at efficient power saving levels. The individual gain control signals from each stage are summed in a received signal strength indicator to provide the overall gain of the apparatus. The overall gain when taken with the amplitude of the apparatus output signal determines the original strength of the desired received signal.

Title: Method for topology analysis in the verification of neighbor and target lists in a cdma network
Inventor: SIMMONS STEVEN MICHAEL
IPC: H04W24/00
Filed: 1999-11-25
Abstract: A method for analyzing the topology of a CDMA network with respect to both neighbor and target lists is disclosed. The method first defines a language that creates an input source file for communicating the layout of the CDMA network. The language expresses the sector-neighbor list relationships of all sectors in the CDMA network. Next, the method parses and builds a directed graph from the input source file to perform topology analysis of the CDMA network. The method then analyzes the input source file and directed graph for possible errors in the network layout that will lead to dropped calls. The method renders a report to the user about those error conditions and emits a file to be used as input into the CDMA database.

Title: Method and system for targeted distribution
Inventor: ST-DENIS DANNY PAUL
IPC: G06Q30/02
Filed: 2000-03-15
Abstract: Typically, advertising over the Internet is either indiscriminate, in that all visitors to a web site receive the same advertisements, or personal records of each visitor are stored and used to tailor advertisements. The indiscriminate method is inefficient as many viewers will not care about the advertisements being received, and the personalized system is largely considered to be an invasion of privacy. The invention provides a manner of targeting advertisements, by basing content on the physical location of the Internet Service Provider (ISP) for that serves the End User.  This way, advertisements can be targeted without having personal records stored on the Internet. The location of the ISP may be determined many ways including: the ISP indicating its physical location, the location being determined from the ISP's IP  Address, or using the Data Link Control (DLC) address or Media Access Control (MAC) address of the ISP.

Title: Downhole pump with bypass around plunger
Inventor: FISCHER CHARLES K JR
IPC: F04B47/02
Filed: 2000-06-23
Abstract: The downhole pump has a barrel with a reciprocating plunger therein.   The barrel has a first one-way valve, while the plunger has a second one-way valve. A barrel chamber is formed between the two one-way valves. The barrel chamber expands when the reciprocal movement between the plunger and the barrel is an upstroke movement and then contracts when the reciprocal movement is a downstroke movement. A bypass channel is provided between the barrel and the plunger so as to provide communication around the plunger and its one-way valve. The bypass channel is open when the reciprocal movement is near an end of the upstroke movement. When open, pressure across the plunger can equalize and gas inside the barrel chamber can vent around the plunger and/or pressure can equalize across the plunger one-way valve so as to prevent gas lock and minimize stress on the sucker rods. The bypass channel can be provided by reducing the diameter of the lower end of the plunger, increasing the diameter of the upper end of the barrel, putting grooves in the plunger or the barrel or by making the barrel out of two sections, namely a lower section and a wider upper section and providing holes in the lower end of the plunger below the plunger one-way valve.
