Abstract: A method and apparatus for transferring eggs from an incubator flat to a hatching tray. The apparatus comprises a table, a frame pivotally mounted to the table, a main air cylinder, a rack and pinion connection between the main air cylinder and the frame, and clamping arrangements located on the frame together with first and second air cylinders for driving the clamping arrangements.

Abstract: There is provided an improved method of cleansing a filter bed utilizing a backwash pump (12) having an inlet line (14) and an outlet line (16). The improved method and system includes two cycle operations. Initially, the filter bed is backwashed to remove contaminants from the filter bed with the backwash pump (12) drawing liquid from an effluent channel (32) through a first diverter valve (18). The fluid flows through a second diverter valve (20) and a first throttling control valve (36) for insert into a backwash shoe (38). In the purging cycle, fluid may be recirculated from the backwash pump (12) through the backwash shoe (38) and then back to the backwash pump (12) with a portion of the fluid being diverted through a second diverter valve (20') into an egress line (42).

Abstract: An improved method of cleansing a filter bed is herein provided utilizing a backwash pump (12) having an inlet line (14) and an outlet line (16). The improved method and system includes two cycle operations. Initially, the filter bed is backwashed to remove contaminants from the filter bed with the backwash pump (12) drawing liquid from an effluent channel (26). A portion of the liquid passing on backwash pump outlet line (26) is passed through a bypass adjustment valve (34) for egress on an outlet line (38) for recirculation to the effluent channel (26). The second stage of the cleansing operation is through a purging cycle where the filter bed is purged subsequent to the backwashing operation for removal of further contaminants from the filter bed.
