Title: Method and system for the detection and measurement of air phenomena and transmitter and receiver for use in the system
Inventor: GJESSING DAG K
IPC: G01S13/95
Filed: 1993-03-15
Abstract: A system and method for the detection and measurement of atmospheric air movement irregularities such as wind velocity vector, clear air turbulence, aircraft induced vorteces and turbulence, by means of electromagnetic waves. An air volume (10) un-der investigation is illuminated by a transmitter (1, 1A, 1B) with a beam of coherent electromagnetic energy (1E), and a resulting wave field (2E) is received and subsequently coherently demodulated and processed in process means to derive information on the existence of the said atmospheric irregularities and furthermore to give specific measurements of related parameters. At least one receiver (2, 2A, 2B) for said resulting wave field (2E), which is due to scattering in said air volume (10), is positioned at a bis-tatic location having a selected distance (2R) from said transmitter (1, 1A, 1B). Said electromagnetic energy (1E) is transmitted at microwave frequencies in a concentrated beam. Transmitter and receiver antennas (1A, 1B, 2A, 2B), respectively, are directed so as to cover said air volume (10) with a scattering angle (.THETA.) chosen to have such a (low) value that scattering from atmospheric irregularities in said air volume (10) has a higher power than noise sources in the system.

Filed: 1993-05-07
Abstract: In the treatment of obstructive sleep apnea, a CPAP flow generator (22) is employed to direct air to a nasal mask (20) fitted to a patient. The airflow from the generator is monitored, and the flow and/or pressure is increased through signal processor (24) when the waveform of the air flow exhibits characteristics corresponding to flow limitation.  The generator may be controlled to repetitively test for waveform variations, in order to adjust the CPAP flow to the minimum level that does not produce flow limi-tation.
Patent CA-2134264-A1 (CA)
Inventor: HANCOX WILLIAM T
IPC: G21G1/02
Filed: 1994-10-25
Abstract: A process is taught for production of Mo-99 from uranium-235 and for managing waste produced therefrom. The process includes separation of the Mo-99 from irradiated uranium and solidification of the waste remaining after such separation. Because of the great reduction in the amounts of waste produced fromthe process over previous methods, the process is of particular use in the large-scale production of Mo-99. Further, the present process results in a reduced process time over previous processes and thereby offers a reduction in the loss of Mo-99 by decay.
Patent CA-2134583-A1 (CA)
Title: Air/fuel ratio controller for large internal combustion engines
Inventor: NUSSBAUM STEPHEN H
IPC: F02D41/14
Filed: 1994-10-28
Abstract: Apparatus, and a corresponding method for its operation, for controlling the air/fuel ratio in a large engine having one or more banks of cylinders with separate intake and exhaust manifolds. Oxygen sensors in the manifolds are sampled periodically to provide the apparatus with an indication of the level of oxygen, and therefore an indication of the level of various pollutants, in exhaust gases dis-charged from the engine. The apparatus, preferably in microprocessor form, computes a fuel control correction based on the difference between the sensed oxygen level and a desired oxygen level in each exhaust manifold. The correction is applied in the form of a change to the pulse width of a binary control signal applied to a solenoid valve. In the illustrative embodiment, the solenoid valve is coupled to a fuel pressure regulator and functions to vent an air chamber in the regulator when the solenoid is actuated. Changing the pulse width of the control signal varies the average fuel pressure and thereby controls the air/fuel ratio, which in turn corrects the oxygen level in the exhaust manifold. The controller also monitors various temperatures in the engine and selectively disables control of the air/fuel ratio when selected temperatures fall outside assigned limits.
Patent CA-2135152-A1 (CA)
Title: Veneer Sorting Apparatus
Inventor: MCKAY DARYL G
IPC: B07C5/36
Filed: 1994-11-04
Abstract: Veneer sorting apparatus for sorting a moving stream of arbitrarily ordered full width,  random width, fishtail and trash veneer pieces in response to a signal representative of a characteristic such as width.   Each piece is deflected into an appropriate output path: one path contains  substantially only full width pieces,  a second path contains substantially only trash pieces, and a third path contains  substantially only fishtail  and random width veneer pieces.   A first vacuum source is coupled to  a  first  series  of vacuum ports positioned closely proximate to and spaced transversely across the moving stream.  Vacuum applied through the ports initially draws all the pieces toward the full width output path. Dampers responsive to the characteristic signal temporar-ily decouple the vacuum ports from the vacuum source upon detection of a trash piece, allowing the trash to fall away from the full width output path.   To further assist in trash removal, an air jet responsive to the characteristic signal is provided adjacent the first vacuum ports to blow trash pieces into the trash output path;  and,  a first pivotable finger downstream of the vacuum ports responds to the signal by deflecting trash into the trash output path. A second pivotable finger downstream of the first finger responds to the signal by deflecting fishtail and random width pieces into the fishtail and random width output path.

Title: Stairtread made of a combination of high quality wood and low quality material
Inventor: BELLEGARDE RENE
IPC: E04F15/04
Filed: 1994-12-22
Abstract: The wooden stairtread has the aesthetic appearance of a solid wood stairtread and presents a structural stability comparable to that of wood treads, but comprises a core layer consisting of lamellas of low quality material glued laterally adjacent to each other. On the top surface of the core layer are glued laterally adjacent to each other top lamellas of high quality wood. Underneath lamellas consisting of high quality wood may also be glued laterally adjacent to each other on the bottom surface of the core layer to form a tread of which the underside is made of high quality wood covering the low quality core. Finally an elongate nose member is applied and glued to a longitudinal edge surface of the core layer.  Use of low quality material such as low quality wood helps to preserve our natural resources and to reduce consumption of high quality wood material becoming every day more rare and difficult to obtain.

Patent CA-2146805-A1 (CA)
Inventor: RIPKA CHESTER D
IPC: F23D14/58
Filed: 1995-04-11
Abstract: A burner for burning a combustible gas comprising fuel gas and air that has been mixed before being supplied to the burner. The burner has a flame holder concavely recessed into a flame outlet. The concave configuration of the flame holder focuses the individual flames on the combustion surface toward a central location where the individual flames interact with and reinforce one another in a direction axial to the burner. Thus very little heat is transmitted directly from the burner in a direction normal to the burner axis. This characteristic of the burner allows it to be used to fire a flue type heat exchangers where the walls of the heat exchanger are very close to the burner without excessive temperatures being produced in the heat exchanger walls adjacent the burner.

Abstract: In practising various sports such as hockey, it is known to provide a target in a desired position such that the shooter strikes or otherwise directs a projectile at the target.  In this invention, the target is portable and can be connected to a fixed object such as the frame of a hockey net.  The target is a band of steel or other sturdy material and of any desired shape.  A pocket is connected to the perimeter of the target for catching a hockey puck, ball or other object which is directed through the perimeter of the target.  A spring is, at one end, connected to the target and, at its opposite end, connected to a clamping device such that the target, spring and clamping device, can be connected to a fixed object such as the goal post or crossbar of a hockey net.  The shot target assembly can be easily connected to and removed from a wide variety of objects.  The spring can absorb any impact caused by a projectile hitting the target without displacing the shot target assembly and without causing damage to the target.
