  • Patent number: 7314556
    Abstract: A panel sector, for a disc filter for separation of liquids from a suspension, includes front and back filter panel assemblies, a sector assembly for mounting the front and back filter panel assemblies, and a top cap for retaining the filter panel assemblies within the sector assembly. Each of the filter panel assemblies includes a frame and a filter material clamped by the frame. The sector assembly includes an outer end plate, an inner core mounting plate subassembly for mounting the panel sector to the disc filter core, first and second side channel subassemblies, at least one structural member extending radially between the core mounting plate subassembly and the outer end plate, and at least one support member extending laterally between the first and second side channel subassemblies. The core mounting plate subassembly and each of the side channel subassemblies have front and back channels for receiving portions of the frame.

  • Patent number: 5247963
    Abstract: An automatic flushing system for poultry watering systems is provided which includes a bypass of the upstream pressure regulator, self sealing caps for the stand pipes and a readily disassembleable automatic flush valve at the end of the supply line. A shut-off valve in the bypass is provided which is actuatable manually or automatically in response to a timer, environmental sensor or water condition sensor. The automatic flush valve opens in response to a predetermined pressure level and connects the supply line to a drain hose. The automatic flush valve can include an end cap which is removable from the flush valve and which facilitates cleaning of the valve and supply line. The self sealing caps prevent leakage out of the standpipes and are especially formed to prevent blow-outs of the seal. Where multiple pressure regulators are used in the supply line, additional automatic flush valves can be positioned in a bypass line around those regulators.
