Title: Method and apparatus for ozone bleaching of cellulosic pulp at low consistency
Inventor: HORNSEY DEREK
IPC: D21C9/153
Filed: 1996-09-23
Abstract: A method of bleaching a pulp at low consistency employs chlorine dioxide and/or chlorine, to partially bleach the pulp, the aqueous partially bleached pulp flows along a sinuous flow path providing a high ratio of flow path of aqueous pulp to length of effective travel of the aqueous pulp. Ozone is introduced to the aqueous pulp at spaced apart locations in the flow path so that a low partial pressure of ozone is established in the flow path which favours chemical oxidation of the lignin and low chemical attack on cellulose. In this way effective bleaching is achieved with reduced use of chlorine or chlorine dioxide and reduced production of chlorinated compounds.

Inventor: GAREAU NORMAND F
IPC: A62B3/00
Filed: 1997-04-17
Abstract: The present invention relates to a safety retrieval device, that is, a device for rescuing from the water a person that fell threw the ice at night. When a person falls threw the ice the effects of hypothermia, particularly in cold water, combined with weight of waterlogged clothing, and perhaps injury, often make it impossible for him to climb back onto the ice unaided. Moreover, those remaining on the ice may find it difficult, if impossible, to haul the person out of the water, particularly on thin ice or severe weather conditions. This invention, the life saving aid retrieval device compromises of a rope with luminescent properties (glow in the dark), enables both the rescuer and rescue to determine the location of the life saving aid, thereby saving precious seconds in an emergency situation, with two handles having retractable sharp ice cups for traction to pull himself out or be assist by a bystander. This lifesaving aid, is portable, compact and lightweight and enables the users to carry the item, either on their person or in limited space situations such as ice fishing, snowmobiling, skiing without sacrificing space in favour of safety.
