IPC: B32B27/12
Filed: 1998-09-15
Abstract: There is disclosed a thermal bonding pattern for nonwoven fabric comprising a pattern having an element aspect ratio between about 2 and about 20 and an unbonded fiber aspect ratio of between about 3 and about 10. It has been unexpectedly found that such a fabric has a higher abrasion resistance and strength than a similar fabric bonded with different bond patterns of similar bond areas. This combination of strength and abrasion resistance has long been sought after.

Title: Navigation system with user definable cost values
Inventor: DEGRAAF BRENT L
IPC: G08G1/0968
Filed: 1997-09-17
Abstract: A navigation system (20) permits the user to designate certain roads or area to avoid when planning a route. The navigation system generally includes a database (28) of road segments and a cost associated with the road segments, such as estimated time or travel across that road segment and estimated length of travel across that road segment. The navigation system (20) determines a route from a selected beginning point to a desired destination by evaluating the cost of the road segments to be traveled in several potential routes and recommends the potential route having the lowest total cost. The user can selectively modify the cost of selected road segments to indicate a preference or avoidance of such roads. By increasing the cost of a road segment, the navigation system (20) is less likely to recommend a potential route which includes that road segment. Similarly, by decreasing the cost of a selected road segment, the navigation system (20) is more likely to recommend a potential route which includes that road segment.

Title: Device and method for easily adjusting working point of squid
Inventor: ITOZAKI HIDEO
IPC: G01R33/035
Filed: 2000-04-03
Abstract: A SQUID bias current adjustment device supplies a sinusoidal current at 40 kHz, for example, to a coil to generate magnetic field at a SQUID. The amplitude of the field corresponds to a half period of a field-voltage characteristic. Voltage generated from the SQUID at this time is filtered by using a filter to pick out components of 40 kHz and 80 kHz.      The picked out signal components are rectified and converted to direct current, and the bias current is adjusted such that the maximum value is obtained. In this way, a SQUID bias current adjustment device can be provided capable of automatically adjusting bias current properly in a short period of time.

Title: Communications channel synchronous micro-cell system for integrating circuit and packet data transmissions
Inventor: WITSCHORIK CHARLES ARTHUR
IPC: H04L69/14
Filed: 2000-06-22
Abstract: The present communications channel synchronous micro-cell system for integrating circuit and packet data transmissions functions to blend both circuit and packet technology together to carry both constant bit rate and variable bit rate traffic with no added packet or jitter delay for constant bit rate traffic and no added circuit setup delay for variable bit rate traffic. This is accomplished by the use of a micro-cell structure for all information that is transmitted over a communication channel. The data stream comprises a series of frames, each of which consists of a predetermined number of micro-cells. The micro-cells are fixed in size, with a header, like Asynchronous Transfer Mode, but their similarity stops there.  The header is a flag which indicates the type of payload that is placed in the micro-cell associated with that header. When the header indicates a payload that is synchronous with the communication medium, that micro-cell is being used as a time slot in a circuit switched sense. When the header indicates a payload that is asynchronous with the communication medium, that micro-cell is being used to transfer packets of data, which are routed by the address data embedded in the header of the packet data, independent of the micro-cell location in the frame.
Patent CA-2312963-A1 (CA)
Inventor: THILI RALPH J
IPC: F02B75/02
Filed: 2000-07-13
Abstract: In the 4-stroke engines currently in use each cylinder and piston combination must do all the work of intake, compression, power and exhaust All of this depends on the precise timing of individual cams for lifters, individual spark plugs, and individual injectors for each and every cylinder/piston combination While the 2-stroke engine needs oil additives to the fuel to prevent excessive wear, that results in a very smokey exhaust.   During the exhaust cycle, all of the exhaust gasses are impossible to expel.  The piston can not travel up to the head, but must leave room for the mechanical operation of the valves. Therefore when the intake cycle starts the fresh clean air is contaminated by the residual exhaust and lowers the power potential that could be achieved if pure air only was present.   Therefore to purge the exhaust and to increase power a Turbo Charger or Blower is added, at the intake manifold.     In present configurations, wasted heat and power is squandered in the exhaust pipe muffler etc, all the flame and heat is smothered (starved for oxygen) producing excess carbon monoxide.   The present four stroke cycle engine must complete two complete revolutions to achieve one power stroke, but with my configuration,  a power stroke is accomplished in one revolution.
Patent CA-2313126-A1 (CA)
Title: Providing subscriber access to a telecommunications network
Inventor: DYER MICHAEL P
IPC: H04Q11/04
Filed: 2000-06-29
Abstract: Voice and data services are delivered to subscribers from a Tier 2 exchange via an optical fibre path to a local distribution unit to which the subscribers are coupled by copper loops. Each subscriber is served via a respective line card at the exchange. Coupling over the fibre path is effected by digitizing analogue signals from the line cards and multiplexing the digitized signals together. At the distribution unit, the digitized signals are de-multiplexed and their analogue form is recovered for delivery over the subscriber loops. In a further embodiment, the technique can be used over a single subscriber line, e.g. to provide data services over a long loop that would otherwise have insufficient bandwidth for such services.

The unloader features a stationary support frame with an open center concept.  Suspended from the support frame is a rotating drive ring, and a telescoping tubular support and auger for distributing and gathering silage. The telescoping tubular support is designed to permit installation adjustment so that the silo unloader can fit into a range of silo diameters and accommodate warpage in the wall of a round shaped silo. A hole former is also secured to the tubular support. A winch assembly may be provided to raise and lower the silo unloader within the silo. Also provided is a drilling apparatus adapted for use with the suspension of the silo unloader. Where the silo unloader is already installed in the silo, the drilling apparatus can be mounted on the suspension in conjunction with the tubular support and auger of the silo unloader, and used to dislodge blockages or enlarge an existing hole through the silage. Where the silo unloader has not been installed, a drilling apparatus can be mounted on a suspension installed in a bottom unloading silo and used to drill a hole through the center of the silage, and a silo unloader with tubular support and auger, can then be mounted onto the suspension within the silo to unload the silage through the newly formed hole.

Abstract: Disclosed are radioactivable compositions, preferably metal alloy compositions containing a metal having shape memory characteristics, and at least one radioactivable isotope comprising a lanthanide series element or mixtures of lanthanide series of elements or other suitable isotope. The radioactivable isotope is present in sufficient concentration (relative to other components of the composition) to deliver an effective radiation dose to a target tissue to achieve a specified therapeutic objective. One of the more advantageous and useful applications for this composition is the formation of medical devices for the treatment of coronary artery disease and the abatement of proliferation of cancer cells. In one of the preferred embodiments of this invention, a radioactivable isotope is incorporated, by isotopic beneficiated combination, with a matrix material such as a nickel/titanium alloy (e.g.  Nitinol metal alloys), or by isotopic beneficiated combination with a biodegradable organic naturally occurring or synthetic polymer so as to form a solid solution; and, the resultant alloy or solid solution, thereafter, formed into a stent, or other suitable form, for selective and targeted delivery of therapeutic and effective amounts of low dosage forms of radiation (principally beta particles) to a specific site or tissue within the human body.
