Title: Ship based gas transport system
Inventor: STENNING DAVID G
IPC: F17C7/00
Filed: 1997-09-26
Abstract: A gas storage system (11) formed of a continuous pipe (10) wound in plural layers, each layer having plural loops. The pipe may be distributed within a container (12), which may serve as a carousel for winding the pipe and as a gas containment device. When containers, each containing a continuous pipe, are stacked upon each other, the weight of upper containers may be born by the walls (16, 18) of lower containers, thus preventing lower layers of pipe from suffering stresses due to crushing by upper layers. A method of transporting gas to a gas distribution facility including obtaining a supply of gas at a gas supply point remote from the gas distribution facility, injecting the gas into a continuous pipe bent to form plural layers, each layer including plural loops of pipe, transporting the continuous pipe along with the gas to the gas distribution facility preferably in a ship (62) and discharging the gas.

Title: Fireplace screen assembly
Inventor: HARRIS ERNIE E
IPC: F24B1/192
Filed: 1999-02-15
Abstract: A fireplace has a glass window and a mesh screen. The fireplace has a viewing opening into a firebox generally surrounded by an enclosure except about the viewing opening. The glass window encloses the opening of the firebox. The mesh screen extends over the glass window opposite the firebox. The mesh window is constructed of a woven wire mesh. The woven wire mesh reduces the amount of incident light to the glass window from outside the firebox, thus reducing the amount of glare perceived from the viewing area. The mesh screen also provides a relatively cool protective barrier in front of the glass window which has the potential of becoming too hot to touch. Various shapes of the mesh window are possible including a bay window-like shape. The screen assembly may be used with various types of fireplaces including direct vent and room air vented gas fireplaces.

Abstract: A perimeter monitoring system is arranged to detect passage across a perimeter of an area. The system primarily includes an emitter (120), a retroreflector (116), a detector (122) and an alarm (146). The emitter (120) provides a modulated visible laser beam (115). The retroreflector is arranged to direct the beam along a segment of the perimeter and return the beam along the segment. The detector (122) includes a device (208) that blocks reception of light outside an angle of less than 5 degrees. One or more local or remote alarms (162) are activated in response to the signal. For example, a remote alarm is located on the inside of a residence window where it is activated by another visible laser beam. Alignment of the peripheral monitoring system is less costly and false alarms are less likely than with known system.

Patent CA-2293239-A1 (CA)
Title: Adaptive bit allocation for variable bandwidth multicarrier communication
Inventor: KECHRIOTIS GEORGE
IPC: H04J11/00
Filed: 1998-06-09
Abstract: Data is distributed among the channels of an asynchronous data subscriber loop (ADSL) communications system in accordance with an adaptive algorithm which from time to time measures the signal to noise ratio of the various channels and finds a margin for each channel dependent on achievement (where possible) of a given bit error rate and a desired data transmission rate. The margin distribution is achieved by augmenting the constellation signal to noise ratio to enhance computational efficiency and allow redetermination of bit allocation tables during transmission as necessary. Pairs of bit allocation tables are maintained at the transmitter and receiver and one table of each pair at the transmitter and receiver is updated while the other pair is in use for controlling communication.
