Abstract

1512534 Variable-flush cisterns NATIONAL RESEARCH DEVELOPMENT CORP 24 Sept 1976 [5 Sept 1975] 36670/75 Heading E1C To provide a cistern 10 with a variablevolume flush the siphon discharge tube 12 (shown primed by a weighted plunger 21 linked to an arm 18 actuated by a handle or button, not shown) has near its upper end a siphon-breaking air-admission duct 27 which is opened to terminate the flush at any desired moment by raising its outer end 28 out of a permanently-full water receptacle 30. The receptacle 30 may be formed by a box 31 of a conversion kit or by a cistern partition (32) and underlies the cistern inlet valve 15. As shown the air duct 27-28 is strapped to the arm 18 so that on depressing the flushing handle the air duct is closed by dipping into receptacle 30. A variable volume partial -flush is produced by releasing the handle at the desired moment; a full flush is produced by holding the handle down.
