Patent CA-2041629-A1 (CA)
Inventor: BEATY ROBERT C
IPC: H01M50/204
Filed: 1991-05-01
Abstract: A thermally controlled equipment cabinet for telephone systems has a gas-tight, sealed compartment for mounting sensitive active electronic components and has jacket 20 partially encompassing at least three sides of the sealed compartment.  The sealed compartment utilizes either forced or natural convection to dissipate the heat generated by the components to the surrounding air.  The heat is then dissipated to the ambient air through a highly heat-conductive corrugated roof and side panels.  The jacket provides a cooling air passage around the sealed compartment and over the corrugated roof removing heat thereof.  Nonsensitive passive components, mounted in the cooling air passage near the air inlet of the jacket, provide protrusions in the cooling air passage causing a slightly turbulent air flow in the passage thereby enhancing heat transfer.  Storage batteries, such as used in telephone systems, are mounted within the cooling air passage near the air exhaust of the jacket.  The warmer air allows the batteries operate at higher and more efficient operating temperatures.

Title: Introduction of medication in ventilator circuit
Inventor: FOLEY MARTIN P
IPC: A61M39/02
Filed: 1991-05-16
Abstract: ABSTRACT OF THE DISCLOSURE Apparatus is provided for injecting medication into a ventilator circuit. An elbow connects an endotracheal tube to the external ventilator circuit.  A port in the elbow is connected to a flexible sheath leading to an actuator receiving an MDI canister.  A catheter extends from the actuator substantially through the sheath to a position adjacent the elbow.   When it is desired to inject medication, the actuator is moved to a position adjacent the elbow, thus projecting the discharge end of the catheter to a position within the endo-tracheal tube, but short of the open end thereof.

Title: Method and apparatus for compression packaging
Inventor: MERRY WAYNE M
IPC: B65B63/02
Filed: 1990-12-13
Abstract: ABSTRACT OF THE DISCLOSURE           The  present  invention provides  a  method  of compacting a sheet article,  for example an article of underwear,  to  produce  a  stable,  substantially  rigid, compacted  article.    This  reduces  space  required  for storage and distribution and facilitates packaging of the article.  Compaction is effected by placing the article, or  a  plurality of  articles,  in  a mould cavity,  and subjecting them to elevated pressure for a certain time. The pressure and time are selected to compact the article sufficiently to form the stable, rigid body, but simultaneously not being so great as to either damage the article or compact it so much that water of other liquid is required to recover the article from its compacted state to its original state.

Title: Apparatus for determining drainage time of papermaking stock
Inventor: HALLEY DAVID G
IPC: G01N1/28
Filed: 1990-09-13
Abstract: The invention is an apparatus and method for measuring drainage time of a papermaking stock suspension (62). The apparatus will automatically measure drainage times of a plurality of samples which will preferably be of differing basis weights. It consists of a sheet mold reservoir (10) and dropleg (26) which index against or away from a table (12) having spaced apart sheet forming locations (14). Operation of the apparatus is determined by a programmable controller which causes stock to be automatically transferred to the sheet mold and the reservoir and dropleg to be automatically and appropriately positioned. After a sheet is formed, the table automatically indexes to the next forming position where the cycle is repeated. The method involves plotting a series of at least three points to determined the slope of drainage time versus the basis weight of the sheets formed. This can be used as an indicator of the drainage characteristics of a stock of given basis weight on the forming section of a paper machine.
