Patent CA-2196626-A1 (CA)
Inventor: WESTON COLIN K
IPC: G05D7/06
Filed: 1997-02-03
Abstract: An automatic continuous flow liquid dispensing device for dispensing liquid onto a receiving surface of an article includes an improved flow control mechanism comprising a threaded elongate shaft retained in threaded engagement by a base member securely attachable to the external housing, so as to be selectively rotatably movable to any one of a plurality of stop positions. The threaded shaft is positioned to be contactable by a valve of the dispensing device, thereby acting as a backstop to preclude the valve from reaching its full flow position, and thus defining a plurality of partial flow positions. An electric motor rotates the threaded shaft in first and second rotational directions, to selected stop positions. Electrical controls are connected in electrically conductive relation to the electric motor for selective control thereof. Sensors are mounted on the dispensing device to sense ongoing conditions of selected parameters representative of specific circumstances related to the operation of the liquid dispensing device, and to generate quantitative values corresponding to the selected parameters. The sensors are connected in electrically conductive relation to the electrical control so as to provide feedback signals thereto. The feedback signals are derived from the quantitative values generated by the sensors. The electrical control process the feedback signals in real time and provide control signals to the electric motor. The control signals are a function of the feedback signals from the sensors, and thereby control the electric motor in accordance with the quantitative values.

Patent CA-2204188-A1 (CA)
Inventor: PAULIN WARREN RICHARD
IPC: B60M1/06
Filed: 1997-05-01
Abstract: In the placement of communications cableing, there are many variations of how it is protected and how it is placed. The usual methods include burying the cable underground or suspending it from poles placed in the ground.    In this invention the communications cableing is encased in a resilient tubing which is attached at ground level to the metal rail tie plates on a railway structure through the use of bolts and metal circle clamps, parallel to the existing rail on a railway track. This method of communications cableing placement can be achieve at a high rate of speed for a fraction of the cost of current placement methods.    The resilient tubing will protect the communications cableing from incidents such as vandalism and acts of nature. A conductive jacket encasing the communications cableing will monitor the rail parallel to the cableing through a signal being generated from a fixed point on the rail which travels through and along the rail. The rail will radiate the signal that will be received by the conductive jacket encasing the communications cableings' core and will carry this signal to devices that will read any variations in the signal. The variations will then be measured using a zero point and the invention will be able to calculate when the rail has become misaligned, buckled or an object is obstructing the rail.

Title: Disposable pull-on pant
Inventor: BUELL KENNETH BARCLAY
IPC: A61F13/49
Filed: 1996-03-29
Abstract: Pull-on garments provided with a continuous belt (38) in the front region (26) and the back region (28) to distribute the forces generated during use in order to better fit the pull-on garment on the wearer. In a preferred embodiment, the pull-on garment comprises a chassis layer (40) comprising a continuous sheet that defines a front region, a back region, and a crotch region (30); a first belt layer (42) joined to the chassis layer in the front region; a second belt layer (44) joined to the chassis layer in the back region; elastic laminate panel members (46, 48, 50) positioned between the belt layers and the chassis layers which laminate is mechanically stretched to form elastically extensible stretch laminates in both the front region and the back region in the side panels (64); and seams (32) joining the front region to the back region so as to form the leg openings (34) and waist openings (36). The continuous chassis layer and belt layers thus form the continuous belt of the pull-on garment. Because the belt layers extend continuously laterally across the waist region and do not cover the entire crotch region, and because the chassis layer is thus exposed in the crotch region, the pull-on garment has a unique aesthetic feature which consumers perceive as providing a cloth-like feel in the waist but containment characteristics in the crotch.

Title: Vacuum/pressure swing adsorption (vpsa) method for production of an oxygen enriched gas
Inventor: LEAVITT FREDERICK WELLS
IPC: C01B13/02
Filed: 1998-01-12
Abstract: A vacuum/pressure swing adsorption method for extracting a more preferred gas from a feed mixture of the more preferred gas and a less preferred gas, employs an adsorbent bed which, on an equilibrium basis, exhibits a selective adsorption preference for the more preferred gas. The method comprises the steps of: pressurizing the adsorbent bed from a medium pressure to a high pressure with a flow of the feed mixture to enable the adsorbent bed to adsorb the more preferred gas. Void gas is fed from the adsorbent bed during the pressurizing to a first storage tank. A further flow of the void gas is fed into a second storage tank, while bringing the adsorbent bed to a low pressure.     At about the low pressure, the more preferred gas is desorbed from the adsorbent bed, while the void gas is fed to the adsorbent bed from the second storage tank. The more preferred gas, which is desorbed, provides a product output. Then the void gas is fed from the first storage tank to pressurize the adsorbent bed to about the intermediate pressure and the process is repeated. When the process is used to produce oxygen, the key is the use of desorption purge at a nearly constant pressure that is selected to produce a steady stream of low purity oxygen (30% to 60%), at a pressure in the range of 60 kPa to 20 kPa using oxygen-selective adsorbents.  A further important feature of the invention is the use of an adsorbent that is appropriately oxygen-selective and is based on equilibrium selectivity, instead of rate selectivity.

Patent CA-2237626-A1 (CA)
Title: Asynchronous data transmission method and arrangement
Inventor: RAESAENEN JUHA
IPC: H04L7/04
Filed: 1996-11-13
Abstract: The invention relates to an asynchronous data transmission when the maximum data rate of the traffic channel equals one of the single user data rates at the terminal interface. Such a situation may occur for example when a satellite system is connected as a base station system to a mobile system. A mobile station (MS) removes a predetermined number of start and stop bits (START, STOP) from between the asynchronous data characters. The mobile station then concatenates the asynchronous data characters (CHARACTER 1-N) without start and stop bits, and the terminal interface status information (OVERHEAD INFO) into a protocol data packet beginning with a start bit (START) and ending with a stop bit (STOP). The mobile station transmits the protocol data packet through a synchronous satellite traffic channel or set of traffic channels to a land earth station. The land earth station extracts the asynchronous data characters and the terminal interface status information from the protocol data unit.
