Patent CA-2145702-A1 (CA)
Title: Magnetically locatable non-metallic optical fiber cables
Inventor: ARROYO CANDIDO J
IPC: G02B6/44
Filed: 1995-03-28
Abstract: The present invention relates to an optical fiber cable which includes magnetically locatable materials within the sheath system thereby allowing the cable to be located after it has been buried. More specifically, at least a portion of the magnetic particles are purposely oriented in a particular alignment based on their magnetic properties. Such an arrangement not only allows the generation of a detection signal which is distinguishable from that generated by a solid metallic pipe, but also can greatly enhance the level of the detection signal generated. The enhanced detection signal provides for more reliable detection of buried all-dielectric cables and also allows them to be located even when buried at greater depths, such as six feet or more. In specific embodiments of the present invention, the magnetic particles may be aligned and/or magnetized either longitudinally, vertically or transversely relative to the cable. Additionally, these various directions of alignment and magnetization may be alternated along the length of the cable to further enhance the detection signal generated in order to establish a means of accurately and cost-effectively locating communications cable after they are buried.

Title: Multiple electromagnetic tiles for boundary layer control
Inventor: NOSENCHUCK DANIEL M
IPC: B63G8/00
Filed: 1993-06-25
Abstract: The boundary layer of a fluid travelling in a mean-flow direction relative to a surface of a wall (100) of a body is controlled by generating in the fluid a magnetic field B B7 (103) having flux lines parallel to the surface of the wall and an electric current density J B7 (109) traversing the magnetic flux lines in the fluid to form a control region. An electrolyte or other conductivity-enhancing material (13) is introduced into the flow to provide a conductivity gradient in the fluid flow in the near-wall region. The magnetic field B B7 (103) and the electric current density J B7 (109) create in the control region a force J B7 X B B7 (131) having a component normal to the surface of the wall that because of the conductivity gradient in the fluid flow near the surface can stabilize or destabilize flow in the boundary layer. A  plurality of such control regions are arranged in an array of control tiles that can be individually actuated to reduce the power required to provide boundary layer control over a given area.

Title: Reflective safety strap
Inventor: SPARLING TONY
IPC: F21V33/00
Filed: 1995-05-24
Abstract: Straps, belts and harnesses have been instrumental in assisting people in all areas of life since early times. Today, these areas can be categorized into the following general areas.            With  animals,  strap  devices   such  as  neck  collars  or  body harnesses   for harnessing domestic dogs and cats, are used.  In the case of livestock such as horses,  goats and sheep,  strap devices such as head halters are commonly used. With wild animals strap devices for attaching tracking equipment or banding codes are used.            With people, strap devices such as belts and harnesses are used to secure clothing and equipment to the body of the person. This equipment can range from knapsacks to jogging pouches to scuba diving pressurised air tanks to parachutes.  In addition strap devices are commonly used to secure separate pieces of equipment to other pieces of equipment,  from plastic instruction pouches secured to utility poles to fire or medical emergency equipment strapped to places in buildings or vehicles.            Currently all these strap devices are made of leather or woven materials  such  as  nylon.  Incorporated  into  the  device  are buckles, rings, hooks and Velcro. These are used for fastening the ends of the device together or to other devices and for changing the device's  size, and for attaching leashes or leads or identification labels and tags.            In addition to using straps for purposes of securing articles, straps  are  used  for  visibility and  identification.  Pet  and livestock  owners  desire  to  make  their  animals  visible  to motorists  at  night.  Joggers,  emergency  workers,  and  others working  outside  at  night  desire  to make  themselves  visible. Safety equipment, emergency equipment and other equipment needed at night also needs to be made sufficiently visible.
