Patent CA-2271226-A1 (CA)
Inventor: TRAN JEAN-MARIE
IPC: H04J13/00
Filed: 1999-05-05
Abstract: A wireless telecommunications system includes at least one base station, at least one mobile station, and power control circuitry implemented in the base station and the mobile station. N/X power control indications sent from the mobile station to the base station are used to provide closed loop power control to N subchannels, where N is a total number of subchannels in use between the base station and the mobile station, and where X is a positive integer having a value within a range greater than or equal to one and less than N such that N/X, in one case, is an integer number. In one embodiment each of the N subchannels is transmitted through a separate one of N adjustable gain stages, and N/X power control indications generated at the mobile station are employed to vary the gain of the N adjustable gain stages. In another embodiment a plurality of adjustable gain stages associated with a plurality of subchannels are controlled using a same gain control signal. In the presently preferred, but not limiting embodiment, the system is a wideband, multi-carrier spread spectrum system, and the N subchannels can be overlaid on up to N other carriers.

Abstract: A clamping arrangement is provided for compression mounted power electronic devices that is assembled from component parts to form a clamping module. The clamping module provides suitable clamping force to a power electronic device interposed between two heat sink arrangements. The clamping arrangement utilizes clamping beams disposed on either side of the two heat sinks and the interposed power electronic device, elongated members that span and retain each end of each clamping beam against relative movement, and an arrangement for applying a desired clamping force to the heat sinks and the power electronic device. The kit of component parts can be assembled into a clamping module about a power electronic device disposed between two heat sinks and is easily assembled or field disassembled from economical parts. The clamping modules are also adapted to be easily and efficiently combined into an overall stack of modules to provide a power electronic assembly of series connected power electronic devices for operation at medium voltages. In a preferred arrangement, the elongated members are implemented via the assembly of end cap assemblies about an elongated member. An arrangement to achieve predetermined clamping forces during assembly is also provided.

Abstract: A security device for laptop- or notebook-type portable computers is provided for the securing of such a computer to a surface. The device comprises, in general, a retainer for engaging the computer's display; positioning structure for moving the retainer into and out of engagement with the display; and a mounting structure therefor which is securable to the surface. The device includes a locking mechanism which functions to fix the position of the retainer a predetermined distance above the surface to trap the computer against the surface and, hence, prevent its removal. The device is adapted to quickly engage and disengage the computer and to provide a minimum of inconvenience with respect to the task of locking and unlocking the computer. When not in use, the device moves substantially out of the way so as to minimize obstruction of the surface on which the device is employed. The device not only presents a visible deterrent, but it also presents an evident and significant physical challenge for its defeat. The invention also provides for mounting the security device to a mini-table which is sized so as to be unable to be concealed easily under garments, coats, etc., or to fit within most briefcases or the like, thereby foiling the snatch, grab and hide techniques of most laptop thieves.

Title: Dissolution of gas
Inventor: HANSON CEDRIC
IPC: B01F5/02
Filed: 1999-10-22
Abstract: Liquid in which oxygen-containing gas is to be dissolved is pumped through a main and distributed into faster-moving subsidiary streams. Each subsidiary stream passes through a turbulence-inducing means and air or oxygen is introduced into the turbulent region of alternate streams. The relative proportions of air to oxygen introduction are varied so as economically and efficiently to oxygenate the liquid. The gas-containing liquid passes through nozzles back into the volume of the liquid at sufficient velocity to cause further turbulence, making gas bubbles shear into smaller bubbles and also agitating the body of liquid.

Abstract: The valve assembly for venting die casting moulds comprises a venting channel, a venting valve communicating with the venting channel as well as an actuating device for closing the venting valve. The actuating device comprises a power pick-up member that is axially movable under the influence of the liquid casting material entering the venting channel. The venting valve comprises a closure member biased against a stop member and operatively connected to an actuating element. The stop member is pivotable by means of the power pick-up member such that the closure member of the venting valve is displaced from its open position to its closed position under the influence of the actuating element.   Thereby, a reliable closing of the venting valve is ensured, even under unfavorable operating conditions.

Abstract: The concept of my invention will have many different applications which I will list. The concept that I have designed is that of making our enviroment cleaner and safer for everyone. The invention is designed to kill germs and bacteria on the surfaces that we touch with our hands each and every day of our life. It will be designed to operate with sensors and nozzles that will release an alcohol based sanitizer that will evaporate after a small amount of time. This sanitizer will be similar to the alcohol based sanitizer which is used on a persons hands. It is my belief that this type of an object cleaner will reduce sickness and disease worldwide. Many infections and illnesses which make us sick sick are not from airborne infectious agents but rather from the objects that we touch, passed on by other people. Sometimes when people go to the bathroom they do not wash their hands properly or not at all. The result is that when someone else uses the washroom and even if they wash their hands, when they leave the washroom and touch the door handle or knob they will pick up the germs that the previous person or persons have left, who may not have washed their hands. If a person then consumes food or rubs their eyes, the germs are then transmitted into the persons body. I believe that a practical explanation for many health illnesses would originate from a persons hands and if we can reduce the number of these germs on our hands I think we would all be a lot healthier. Furthermore, in hospitals where many people are sick these types of devices would be invaluable.

Title: A railroad hopper car door assembly
Inventor: GALVAN GUADALUPE L
IPC: B61D7/28
Filed: 1999-05-12
Abstract: A discharge door assembly (42) for a bottom dump covered railroad hopper car (10). The discharge door assembly (42) includes a plurality of longitudinally mounted discharge doors (44) arranged in end-to-end relation across a bottom of the hopper car (10), with each discharge door (44) being movable between open and closed positions about pivot axes (46A) disposed parallel to and adjacent a longitudinal axis of the hopper car (10). A door operating mechanism (50) including a single powered actuator (52) operates all of the discharge doors (44) substantially simultaneously to effect rapid discharge of matter from the hopper with significantly less operator involvement. The door operating mechanism (50) further includes a lock (100) for releasably holding the discharge doors (44) in a closed position. A venting system (150) inhibits imploding of the walls of the hopper car (10) upon discharge of particulate matter from the car (10). Deflectors (160) are arranged on opposite sides of the hopper car (10) to combine with the pivoted discharge doors (44) in limiting the discharge pattern of material from the hopper car (10) to a relatively narrow pattern or stream disposed between the rails on which the hopper car moves.
