Inventor: VALENTI JAMES P
IPC: B65D85/66
Filed: 1999-07-08
Abstract: The apparatus is a storage and transport rack for deformable rolled goods. One or more shelves each support a single layer of rolls. The shelves have an open input side for loading, a padded backstop opposite the input side, and unobstructed ends for unloading individual rolls with a ram pole lift truck. The upper surface of the shelves is tilted relative to the horizontal with the input side higher, so that the rolls move to the padded backstop, and a sloped ramp at the input side of the shelves starts the rolls down the shelf and assures that the rolls will not roll off the input side. For transport, the rolls are anchored by the use of straps tightened between "D" rings attached at the backstop side of the shelves and "D" rings on plugs inserted into the hollow cores of the rolls.

Patent CA-2289336-A1 (CA)
Title: Ventilator system and method
Inventor: HAGLID KLAS C
IPC: F24F11/76
Filed: 1999-11-09
Abstract: The ventilator system and method use a isolating heat exchanger to selectively transfer heat between exhaust air leaving an enclosed space and outside air entering the enclosed space. The system operates in three basic modes, under the control of a microprocessor-based controller which is responsive to the temperatures inside and outside of the enclosed space. In the heating mode, heat is transferred from the exhaust air to the outside air when the enclosed space requires heating. In the cooling mode, heat is transferred from the outside air to the exhaust air when the outside air temperature is higher than that in the enclosed space. In the supplemental cooling mode, heat transfer between the exhaust and outside air is reduced or eliminated when the outside air temperature is below the desired temperature in the enclosed space and cooling is required. In the heating mode, the heat exchanger is selectively heated when necessary to defrost it. A by-pass is provided for the introduction of outside air in order to avoid heating of the outside air by the exhaust air during the supplemental cooling mode of operation, and/or provide fresh air to the enclosed space without cooling the heat exchanger while it is being defrosted.

Title: Methods and/or systems for selecting data sets
Inventor: WEEKS RICHARD
IPC: G06F17/30
Filed: 1998-08-28
Abstract: Methods and apparatus for identifying associated key words (1035) in a data set (1000). Associated key words are identified by a parser (1020) which firstly operates to extract key words from a data set (1000). These key words are then analysed by the parser (1020) to identify which key words, if any, have an association as determined by a predefined set of rules. These rules are grammatical and include, for example, two keywords both being nouns that occur one after the other without intervening low value words. A similar rule applies to nouns followed by verbs but does not extend to verbs followed by nouns.  These rules allow terms and phrases such as "information technology" and "wide area network" to be identified as associated key words (1035) rather than as individual and unrelated key words.
