Title: Peat fibre water removal by cyclonic action, vacuum and heat
Inventor: GOODWIN ERNEST R
IPC: F26B19/00
Filed: 1991-04-02
Abstract: ABSTRACT         PEAT FIBRE WATER REMOVAL BY CYCLONIC ACTION, VACUUM AND HEAT          This invention for the removal of water entrapped  in peat fibre cells is an apparatus  that also employs  a process of  heating the water in each peat fibre cell while in suspension  and under  negative (vacuum) pressure to the point whereby  the water becomes a gas  (steam) and is expelled  from  the  peat  fibre  cell.  The apparatus  consists  of a suspension apparatus (cyclone) connected to a separator apparatus cone (cyclone). Hot air is allowed  to enter the tube  at the bottom of the suspension cyclone,  wetted peat  is allowed to enter  near the top of suspension cone tube, and the peat will remain  in the tapered cone of the suspension cyclone in residence until the required amount of water is removed from the peat fibre cells to reduce its weight. As the peat fibre weight  is reduced because  of the loss of water, the peat fibre will gradually be lifted higher by the hot air stream until it is then passed over to the separator cyclone by the connecting duct between the two cyclones. Under controlled vacuum  this water gas (steam) will not re-enter the peat fibres while contained in the apparatus  in a heated condition. After passing into the separator cyclone, both the peat and the steam (water extracted from the peat) are subjected to centrifical force (spinning). Because of its particle weight, the peat fibres will be thrown  to the  outside  perimeter  of the  separator body and will gradually spiral downward to a rotary air lock (valve) where they will be extracted. The steam will be extracted by a fan  which develops the negative pressure (vacuum), out through  a central  tube at the top of the seperator cyclone and through a duct to this fan to be expelled to atmosphere. The temperature of the hot air applied, the vacuum that is developed by the extractor fan and the moisture content of the peat as it enters the system will govern the amount of production flow.

Abstract: ABSTRACT      A technique is provided for controlling and managing processes or systems such as a communications network.  The process or system is modelled in memory in object-oriented form.   Each  resource  of  the  process  or  system  has  a corresponding field in the model, which can be composed of data  and  executable  code.   Inter-relationships  between fields  within  the  model  are  designed  to  correspond relationships  between  the  resources  in  the  process  or system.  When the system or process changes, this change is communicated to the model, causing changes to be made in the data in the corresponding fields, and possibly causing the execution  of  code  to  cause  corresponding  changes  to associated inter-related resources in the process or system and their corresponding fields within the model.   In this way, a  real  time  model  of  the  process  or  system  is maintained,  and changes to the process or system can be addressed directly to the model,  which will provide the appropriate changes to the process or system.
