Patent CA-2185751-A1 (CA)
Inventor: ANSTEY NIGEL A
IPC: G01V1/00
Filed: 1996-09-17
Abstract: In three-dimensional seismic surveys using the Vibroseis system, cost savings can be made if multiple sources are used simultaneously, into the same set of geophones. Each source radiates a distinctive source signal, so that reflections generated by each one may be separated from those generated by the others. These signals should have little or no correlation with each other, and each should be substantially immune from harmonic distortion present in any of the others. The invention employs long but identical swept-frequency signals, for which the time to sweep through one octave exceeds twice the maximum seismic travel time of interest. For one swept-frequency signal a frequency-time space is defined between the signal itself and a nominated harmonic (for example, the second), and the other swept-frequency signals are accommodated within partitions of this frequency-time space. The invention is particularly appropriate to inexpensive swinging-weight vibrators.

Title: Automatic by-pass valving systems and methods
Inventor: GAINES BRYAN
IPC: H02G15/24
Filed: 1996-09-24
Abstract: An automatic by-pass valving system for an electrical cable system wherein insulating fluid at a pressure above atmospheric pressure is supplied to an electrical power cable, such as a pipe-type or self-contained cable, having a fluid flow channel and having at least one hydraulic stop interrupting the flow of fluid between the channels of adjacent portions of the cable which are at different elevations. The valving system comprises a check valve, which allows fluid flow only in a first direction, from the lower elevation portion to the higher elevation portion, and a flow-limiting valve, which allows fluid flow only in a second direction, from the higher elevation portion to the lower elevation portion, at a reduced rate. Preferably, a relief valve is also provided to allow fluid flow in the second direction at a higher rate if the fluid pressure difference in the second direction is exceeded by a predetermined amount. The valving system limits the loss of the insulating fluid from the cable when the lower elevation portion is ruptured, protecting the environment, while permitting a limited flow from the point of rupture to protect the cable from contamination.

Title: Hydrocopter
Inventor: FAGERUDD GLENN
IPC: B60F3/00
Filed: 1995-05-17
Abstract: The present invention relates to a hydrocopter. A hydrocopter is a vehicle by which it is possible to move over water, particularly in an archipelago, under difficult conditions, e.g. during the thaw. The waterproof hull of the hydrocopter bears against the underlying surface, such as snow, ice, slush or water, and is driven forward by a propeller mounted on top of the hull. The problem with the current hydrocopters is that they are very difficult to steer and uncomfortable to ride in. Division of the hydrocopter hull into two portions (1, 2) connected to each other by a hinge joint (3), in accordance with the invention, makes it possible to use frame steering. This new structure makes the hydrocopter easier to handle. The invention provides a vehicle which has a small turning radius and which is steerable even at very slow speeds.
