Title: Corona method and apparatus for altering carbon containing compounds
Inventor: CAMAIONI DONALD M
IPC: A62D3/00
Filed: 1997-09-08
Abstract: The present invention is a method and apparatus for altering a carbon containing compound in an aqueous mixture. According to a first aspect of the present invention, it has been discovered that for an aqueous mixture having a carbon containing compound with an ozone reaction rate less than the ozone reaction rate of pentachlorophenol, use of corona discharge in a low or non-oxidizing atmosphere increases the rate of destruction of the carbon containing compound compared to corona discharge in an oxidizing atmosphere.  For an aqueous mixture containing pentachlorophenol, there was essentially no difference in destruction between atmospheres. According to a second aspect of the present invention, it has been further discovered that an aqueous mixture having a carbon containing compound in the presence of a catalyst and oxygen resulted in an increased destruction rate of the carbon containing compound compared to no catalyst.
Patent CA-2268488-A1 (CA)
Inventor: MORRISSEY PAUL DOUGLAS
IPC: E04H13/00
Filed: 1999-04-09
Abstract: This invention is so designed as to allow a completely new format relating to Remembrance Monuments or Gravesite Markers.  At present, in most cemeteries or graveyards, polished marble limestone plaques or monuments identify the remains of a particular individual.  Generally, as is the case on most of these remembrance monuments, the name of the deceased individual, date of birth, date of death, and at times a small notation, such as "May he/she rest in peace", is conveyed.  The Illuminated Remembrance Monument is so designed as to allow for much more information, basically, a biographical account of the person's life, family, and other information of interest.  Also, a favourite photo of the person and any symbol, i.e. World War Veteran or plaque of regiment, etc, and if requested a photo of a religious icon or any such preference so chosen.  The self contained illuminated screen can be permanently lighted for viewing or a one hour timer can be used for a more personalized viewing (discreet) or if so desired solar energy for daylight viewing only.  The permanently set screen would be no bigger than the average headstone monument now in existence, in order to allow a dignified respect for the deceased.  The purpose of the Illuminated Remembrance Monument is to allow family members and other visitors a respectful understanding of the deceased person as to his/her noteworthy accomplishments in life.  It should also hopefully provide a small upliftment for family members or friends by way of a less sombre or morbid headstone plaque.  In essence it should give the deceased an identify which he/she would not otherwise have at the gravesite. The lightness of the hard plastic, while permanently set, can if so desired be changed should family members request it at any time interval they may wish.  This is in essence a biographical account of one's life with the information put together by the deceased as his/her own epitaph before death, or by one's family members or friends.

Filed: 1999-10-29
Abstract: A spray application apparatus and method, well suited for use in a plywood production resin spray line, provides automatic control of the spread rate of resin applied to the veneer layers built-up to form plywood panels. In lieu of the conventional trial and error method of manually adjusting the height of a spray nozzle to adjust the spread rate, a controller, actuator, and various sensors are utilized in conjunction with a novel control algorithm to achieve continuous automatic spread rate control. The control effectively compensates for variations in process parameters (e.g., resin flow rate, conveyor line speed and veneer temperature) during a production run, whereby product quality is increased with reduced resin consumption. The controller is easily and effectively calibrated without the need to obtain accurate initial values of the variable process parameters.
