Granted: 2011-07-05
Abstract: The invention relates to a mouthpiece intended for a device that is used to assess the sensitivity of the pharynx of an individual. For this purpose, an open mouthpiece (1), which is fitted with a thin guide tube (2) having one articulated end (4), is inserted into the subject's mouth. A pipe (9) is introduced into the guide tube by means of the mouthpiece, under observation, until it touches the subject's palate. A measurement scale (1), which is disposed on the tube opposite the second end of the guide tube, is observed and the tube is subsequently withdrawn over a pre-determined distance, e.g. pulled out by 1 cm, and fixed in said position on the guide tube. A variable gas flow is injected into the pipe and reaches the pharyngeal mucous situated opposite the pipe. The sensitivity of the subject's pharynx, measured using the sensitive perception threshold, is determined using the lowest flow value perceived by the subject.

Abstract: The invention relates to a method of treating manure such that odour from th e manure is significantly reduced or eliminated and producing therefrom recyclable water, value-added biosolids and ammonia. Specifically, the manur e is combined with lime at high pH. The material is mixed under negative pressure and the basic conditions cause ammonia to be evolved from the manur e which is then drawn off and recovered. A coagulating agent is then added whi ch further promotes floc formation within the manure. Following further mixing, flocs are separated from the liquid portion. A struvite-promoting chemical a nd a coagulant are then added to the liquid portion which causes further floc formation, and the flocs are again separated from the substantially clear liquid. It is of note that as a result of this process, the solids are highl y hydrophobic and dry very quickly. It is of further note that solids isolated from either step can be combined and sold, for example, as fertilizer, as discussed below. The clear liquid can be used, for example, in barn washes o r for horticultural watering.
