Patent CA-2244707-A1 (CA)
Inventor: WALDNER ROBERT
IPC: A61M15/00
Filed: 1998-08-05
Abstract: A limiting valve (4) is provided in an inhalation therapy unit with a valve member (13) which closes an air through opening (12) in the idle state and corresponding to the pressure difference occurring over the valve opens same substantially proportionally up to a threshold value. If the threshold value is exceeded, the valve member (13) abuts against a limiting member (16) which limits the movement of the valve member (13) and the air passage orifices (17) of which are partially closed by the valve member (13) so that air can only flow through the air passage auxiliary orifices remaining free. In this manner the patient using the inhalation therapy unit is urged to breath in the range below the threshold value, as his respiration above the threshold value is opposed by a considerably higher resistance.

Patent CA-2247682-A1 (CA)
Inventor: PEINEMANN KLAUS-VIKTOR
IPC: B01D53/047
Filed: 1998-09-21
Abstract: A process for the separation/recovery of gases is descrribed where the desired component to be separated from the gaseous mixture is present in low/very low molar amount and/or low/moderate pressure, the process comprising contacting the gaseous mixture with a separation membrane unit containing high permeability/medium selectivity membranes which separate the feed stream into a permeate stream, enriched in the desired component and at a lower pressure and a retentate stream lean in the desired component and at a higher pressure. The retentate stream is made to convey its pressure to the permeate stream which then is directed to an adsorption PSA unit for further purification of the permeate stream so that the effluent stream from the PSA unit which contains the purified component has a purity of up to 99.90%. The process is useful for separating hydrogen from refinery off gases such as FCC gases and can also be applied to other gases such as helium and any other valuable gases present in gaseous streams in low to very low molar contents and low to moderatepressures.

Title: Automatic routing method
Inventor: SHINOMIYA NORIKO
IPC: G06F17/50
Filed: 1998-09-22
Abstract: First, initial routing is performed on a net. If a design rule error exists in a wire already routed as a result of the initial routing,  the wire already routed,  causing the design rule error,  is removed.  Next,  if the wire already routed and removed is a wire interconnecting a movable terminal,  freely  placeable  within  a  predetermined  region,  to another  terminal,  then  the movable  terminal  is  displaced within the predetermined region and the removed wire is re-routed such that the displaced movable terminal is interconnected to the other terminal.  Accordingly, the movable terminal can be located at an appropriate position within the predetermined region in accordance with the situation of surrounding wires.   As a result,  routing results of a higher density can be obtained.

Abstract: For the production of a photographic print of an original present in electronic format, optical representations (D) are produced from sequentially changing strip-shaped portions of the original by way of an electro optical, pixel wise operating converter device (3) and these optical representations (D) are projected onto a strip-shaped exposure region (E) on the copy material (P), whereby the strip-shaped exposure region (E) and the copy material (P) are moved relative to one another and at an essentially constant speed in a direction transverse to the longitudinal extent of the strip-shaped exposure regions (E), so that successively the image information of the whole original is exposed onto the total available surface of the copy material (P). Each strip-shaped portion of the original is thereby divided into at least two strip-shaped sections positioned one behind the other in longitudinal direction of the portion, separate optical representations are produced from the sections by way of the electro optical converter device (3) and these separate optical representations of the sections are projected onto the copy material (P) in at least two strip-shaped partial exposure regions (E1, E2) which are positioned one behind the other in longitudinal direction and together form the strip-shaped exposure region (E).  A digital micro mirror field is preferably used as the electro optical converter device (3). In this manner, large format photographic prints of high quality can be produced with relatively low constructive cost by using conventional converter devices.

Patent CA-2288877-A1 (CA)
Inventor: BOYS JOHN TALBOT
IPC: B60M7/00
Filed: 1998-05-04
Abstract: Inductive power transfer across an extended gap (100) from a primary conductor (119) is provided by means of a resonant intermediate loop comprised of capacitor (118) with inductor (117) - perhaps simply a non-coiled wire -carrying a larger resonating current, that can in turn generate an inductive field to be collected by a pickup coil (120). This loop may increase the transfer rate or reduce the alignment accuracy required of an IPT system, useful for vehicles as well as for lighting and display purposes, and also offers frequency-stabilising features. An electroluminescent advertising panel may be powered from a sine-wave oscillator at 1.2 kHz; its DC power at 50 volts collected by a controlled secondary pickup coil tuned to a system frequency of 15 kHz and placed near to an intermediate pickup coil; also resonant at the system frequency and which is driven by inductive coupling from a primary conductor fed with alternating current at the system frequency.
