Title: Self-tensioning fencing system
Inventor: SPECHT PAUL
IPC: E04H17/06
Filed: 1994-08-12
Abstract: ABSTRACT OF THE DISCLOSURE      A self-tensioning fencing system includes a mounting batten, made of plastic or metal, which is mounted directly to a structural support such as a fence post using standard nails, screws or bolts as required according to the type of a particular fence post.  The mounting batten may be a solid or a thick walled hollow section elastic extrusion or a metal form.  The mounting batten is secured to the structural support post so as to space the plastic grid material away from the support post to allow the plastic grid material to be tensioned at a spacing from the structural support posts.   A channel batten made of pre-coated cold rolled steel mounts over the plastic batten and serves to clamp plastic grid fencing material between the mounting batten,  and the channel batten.  The channel batten when drawn tight against the mounting batten serves not only to firmly attach the fencing material to the support post but acts as a tensioning device.   The amount of tensioning take-up provided by the channel batten is dependent upon the respective cross-sectional dimensions of the mounting batten and the channel batten.  In a typical application, the tensioning capability of the channel batten is in the range of 3/8 of an inch to 7/8 of an inch at each support post, and preferably 5/8 of an inch, dependent upon the plastic grid material used and the size and shape of the mounting batten and the channel batten.

Title: Electric power bar-b-q grill set
Inventor: CHIEN SU-CHEN
IPC: A47J27/62
Filed: 1994-12-23
Abstract: The electric power B-B-Q grill set, easy to use and clean,  is  composed of a shell base,  a lid,  a partition  plate,  a  heating  element  assembly,  an insulated  electric  socket,  a  cooking  grid  and  an electric  unit.  The  shell  base  and  the  lid  are symmetrical  to  each  other  and  they  both  are rectangular-shaped plates with peripheral area larger than bottom area, which contributes to the advantage of  not  only  increasing  the  grilling  zone  but decreasing the packing size of the entire set.  The wire of the heating element assembly is wound like the letter U,  which makes the heat generated be evenly distributed among the grilling zone.  Furthermore,  a probe thermostat is affixed to the electric unit, and thus after the probe goes through a specific hole in the insulated electric socket and reaches the vicinity around the heating element assembly attached to the shell base, the probe senses and adjusts the heating condition of the heating element assembly; therefore ensures the safety of using this device.
Patent CA-2139238-A1 (CA)
Title: Quantized coherent rake receiver
Inventor: DENT PAUL W
IPC: H04B1/7107
Filed: 1994-04-29
Abstract: An implementation of coherent diversity combining in a RAKE receiver that uses energy in signal echoes by integrating information from main-path and bit-period-delayed signal propagation paths to remove echo distortion, or time dispersion, is described. If delayed by one chip in a CDMA system, such echoes appear as uncorrelated interference. The RAKE receiver correlates a despreading code with the current (main-path) signal samples and with the signal samples delayed by 1, 2, 4, ... bit periods, and combines the correlation results to determine the information content of the signal. After appropriate conditioning, the received signal is digitized and the signal samples are stored.      Groups of samples are Fast Walsh Transformed, and the real and imaginary transforms are scaled according to a table of coefficients; the scaled results are stored. Weighted, scaled transforms of groups shifted by 1, 2, 4, ... samples are accumulated, and the index of the largest-magnitude accumulation is used to select real and imaginary transform values.
Patent CA-2139716-A1 (CA)
Inventor: LALANDE PHILLIP T
IPC: E21B31/08
Filed: 1995-01-06
Abstract: A reverse circulation procedure is set forth in which selected shoes are attached to a reverse circulation tool.      Debris, junk and other trash accumulating in a well borehole is captured and removed. The circulation delivers fluid flow in the annular space downwardly at the bottom of the tool of the present disclosure which is directed in the vicinity of a shoe affixed to the lower end. Trash or debris is captured by this process. In one instance, the trash is captured in an elongate container below the reverse circulation tool. In another instance, the trash is collected within the tool itself. The tool has a fluid flow path through an inner tube which is selectively perforated and which directs flow upwardly to one or more deflectors to assure that junk or trash does not flow through the tool.

Patent CA-2142917-A1 (CA)
Title: Casing valve
Inventor: REINHARDT PAUL A
IPC: E21B43/26
Filed: 1995-02-20
Abstract: An apparatus and method for producing through a casing without perforation are disclosed. The casing can be rotated while it is cemented and comprises of a multiplicity of sliding sleeve valves. Each of the valves selectively covers aplurality of pistons, each of which preferably has a rupture disc mounted therein. A pressure-regulating device is provided in association with each rupture disc to ensure retention of sufficient internal pressure in the tubing such that all discs eventually burst without any short circuiting through the discs which ruptured earlier. The outward movement of the pistons acts to assist in fracturing the for-mation. Thereafter, the pressure used to rupture the discs aids in further channel-ing the fluid energy of the fluid rupturing the discs, as well as putting additional pressure on the movable pistons to further stress fracture the formation. As the piston is pumped outward, the grease that is held captive within the piston assembly is forced outward through a bladder. As the grease is pumped out, it displaces the cement slurry and flushes the face of the formation directly in front of the piston. Serrations on the end of the piston assembly concentrate the stresses, causing the piston assembly to bite into the formation. As the piston continues to penetrate the formation, the grease is ejected through the serrations, which helps to further flush the face of the formation. The ejected grease also tends to act as an inhibitor which prevents the cement from setting up in the area around the piston. The interior of the piston assembly will still contain greasewhich helps prevent the temporary restriction from dissolving.

Patent CA-2147098-A1 (CA)
Title: Coupling assembly
Inventor: ZIMA LEONARD C
IPC: B08B15/00
Filed: 1995-04-19
Abstract: A coupling assembly (56) for coupling an exhaust system to a pipe through which hot gases are discharged. As illustrated, the coupling assembly (56) couples the exhaust pipe (54) of a vehicle (16) to a flexible exhaust suction hose (42) of a vehicle emission capture system (10) of the type that discharges vehicle exhaust gases from within a structure (12) to a location outside of the structure.  The coupling assembly includes two portions, one portion being a rubber-like boot (62) which is secured to the free end (42.3) of a flexible suction hose (42), the rubber-like boot carrying near its free end (62.2) a garter spring (64), and the other portion of the coupling assembly being a ball adaptor (60) which may be secured to the tail pipe (54) of a vehicle.  The ball adaptor has a connection portion (60.1) and a spherical portion (60.3) through which hot exhaust gases may pass.  The major external diameter of the spherical portion of the ball adaptor is slightly greater than the internal diameter of the garter spring (64).  By following this design it is possible to slip the garter spring (64) loosely over the ball adaptor (60) to connect the flexible exhaust hose (42) to the tail pipe (54) of the vehicle, the garter spring (64) permitting a disconnect from the tail pipe as the vehicle exits a structure.  When the two portions are assembled together, the boot portion is loosely supported by the ball adapter permitting the boot to freely rotate relative to the ball adaptor as the vehicle is moved, and to permit cooling ambient air to enter the flexible hose.

Patent CA-2151372-A1 (CA)
Title: A rapid tree-based method for vector quantization
Inventor: ACERO ALEJANDRO
IPC: G10L19/02
Filed: 1993-12-29
Abstract: A fast vector quantization (VQ) method and apparatus is based on a binary tree search in which the branching decision of each node is made by a simple comparison of a pre-selected element of the candidate vector with a stored threshold resulting in a binary decision for reaching the next lower level. Each node has a preassigned element and threshold value. Conventional centroid distance training techniques (such as LBG and k-means) are used to establish code-book indices corresponding to a set of VQ centroids. The set of training vectors are used a second time to select a vector element and threshold value at each node that approximately splits the data evenly. After processing the training vectors through the binary tree using threshold decisions, a histogram is generated for each code-book index that represents the number of times a training vector belonging to a given index set appeared at each index. The final quantization is accomplished by processing and then selecting the nearest centroid belonging to that histogram. Accuracy comparable to that achieved by conventional binary tree VQ is realized but with almost a full magnitude increase in processing speed.

Patent CA-2162938-A1 (CA)
Inventor: PAPADOPOULOS HARALABOS C
IPC: H04W72/10
Filed: 1995-11-15
Abstract: An apparatus and method for reducing the runlength of dropped packets in multiple access cellular communication systems.  The invention is particularly well suited for use in time-division multiple access (TDMA) systems such as, for example, shared time-division duplexing (STDD) systems, and TDMA/TDD  systems with  speech activity detection  (SAD). Frame time or frequency slots for communicating information are allocated to a first set of active users.  A second set of active users which are not allocated a slot in a given frame are identified.   At least one of the users in the second set which remains active in a subsequent frame is provided with a priority in obtaining an allocated slot in the  subsequent  frame.    In  one  embodiment,  the  slots allocated to particular active users in the given frame are shifted by at least one slot position if the same users are allocated slots in the subsequent frame.   The priority allocation and slot position shifting may be implemented by circular interleaving of the first set of users which have been allocated slots in the given frame with the second set of users which remain active but were not allocated slots in the given frame.  The circular interleaving may be utilized with fast speech activity detection  (FSAD)  in order to further reduce dropped-packet runlengths.
