Title: Separation method
Inventor: PIERSON HENRI GERHARD WILLEM
IPC: B01D37/02
Filed: 1992-09-09
Abstract: A method of separating solid particles from slurry comprises filtering to provide a damp filter cake and then adding a liquid densification aid to the filter cake to promote densification of the cake. The method is useful for separation of inorganic, generally crystalline, materials from aqueous slurries, for example. Suitable densification aids are flocculating agents such as solutions of alginates and gelatin, and surface active agents. The densification aids promote closer packing of solid particles in the filter cake and assist removal of residual liquid component trapped in interstices between particles. As illustrated, gypsum slurry is filtered on a moving filter belt to form a cake which is sprayed with detergent solution at 29, to consolidate the cake, and then with water at 30 to remove the solution. The washed cake may then be dried. <IMAGE>

Filed: 1994-02-28
Abstract: A mouth-to-mouth resuscitation device is characterized in that it has a lower casing 11 and an upper casing 13 separated by a pliable and elastic diaphragm 12. The diaphragm 12 is held up by two struts 111 affixed to the lower casing 11 and urged against the bottom of a blow-in portion 133 of the upper casing 13 to seal any communication between the two casings 13, 11 and thus prevent air from leaking into casing 13 from casing 11 under normal condition. When the diaphragm 12 is urged by air pressure from blow-in portion 133 of casing 13 portions of the diaphragm 12 not being in contact with struts 111 will be bent down to allow air to flow into the lower casing 11. And when the air pressure from said blow-in portion stops, the diaphragm 12 will return to its normally closed portion and seal the upper chamber from the lower chamber. A transparent stopper 14 is located between the two casings to shield exhaled air from the patient from coming into contact with the first-aid person. <IMAGE>
