Patent CA-2316023-A1 (CA)
Inventor: HEINS NICHOLAS
IPC: E04H17/16
Filed: 2000-08-10
Abstract: The present invention relates to a fence frame and more particularly to modular interconnecting rails and posts to frame a fence. The invention disclosed allows for a simple means of building a fence frame comprising a rail, a post and a single piece coupling. The post includes opposing surfaces that define a channel or other interface profile such as a protrusion. The rail includes at least one surface that defines a channel or other interface profile such as a protrusion. Each of the channels or interface profiles run substantially parallel to the axis of the post and rail as the case may be.  The coupling then joins the post and rail. The coupling includes one end that comprises two arms for engaging the opposing channels or profiles on the post. The coupling also includes a second end that is shaped to positively engage the channel or profile on the rail. When coupled, the post and rail are then able to slidably adjust relative to one another. In one embodiment of the invention disclosed the post and rail have essentially the same cross-section and, therefore, are interchangeable.

Abstract: A sorbent composition and process designed for removing oil or oily substances from the surface or upper layer of a body of a water. The sorbent composition consists of raw peanuts hulls crushed to a plurality of particles of predetermined dimensions. The composition further comprises crushed raw peanut kernels provided to create a hydrophobic/oleophilic protective film around those particles. Protective film is formed by treatment of the mixture in a rotary kiln at a predetermined temperature and a restricted air flow. An apparatus for removing oil or oily substances from a surface or upper layer of a body of a water comprises a flexible ballast feeding pipe containing the sorbent composition. The pipe is immersed on predetermined depth below an oil spill water surface area and contains a number of injection nozzles distributed along the pipe. The injection nozzles are provided to eject the sorbent composition from the pipe into an underwater medium to facilitate a uniform sorbent mixture distribution over the area polluted by the oil spill. Sorbent composition is capable to ascent immediately to the surface of the water to form a second layer that floats below an oil spill layer and insures an unavoidable mutual physical contact with this oil spill layer.

Inventor: LAROIA RAJIV
IPC: H04L5/02
Filed: 2001-01-12
Abstract: Improved timing synchronization and access control techniques for use in an orthogonal frequency division multiplexed (OFDM) wireless system or other type of wireless communication system. In accordance with the invention, an uplink synchronization and access control system is provided in which mobile stations transmit certain timing and access signals in dedicated intervals in an uplink stream. Access control is illustratively implemented as a two-stage process in which a given mobile first transmits a generic uplink access signal in one of the intervals. If this access is accepted, the base station transmits an access acknowledgment containing initial timing and power corrections, along with initial channel assignments on which the mobile can initiate a call set-up process. For re-synchronization, mobiles transmit timing synchronization signals in the dedicated timing and access intervals. The base station measures the arrival time of the signals, and sends back appropriate timing corrections. The invention thereby ensures that orthogonality between mobiles is maintained.

Title: Data compression method and apparatus with embedded run-length encoding using mathematical run processing
Inventor: COOPER ALBERT B
IPC: H03M7/40
Filed: 2000-04-18
Abstract: The diclosed data compressor receives an input stream of data characters and provides a corresponding stream of output codes. The compressor provides a sequence of numerically increasing output codes corresponding to numerically increasing contiguous segments of a detected run of the same character. The number of characters in the detected run is determined and a mathematical algorithm, using the number of characters in the run, mathematically generates the appropriate sequence of codes. In later encounters of a previously processed run, the stored data is accessed and the stored codes corresponding to the run segments are output as appropriate. Non-run characters of the input stram are transmitted directly in synchronism with incrementing the codes of the code sequence.
