Patent GB-201311249-D0 (GB)
Title: Wastewater treatment system
Filed: 2013-06-24
Abstract: A wastewater treatment system 1 comprises an outer tank 10 which is open at one end and an inner aeration chamber 20 mounted within the outer tank during use, which is open at opposing ends. The outer tank generally increases in internal diameter towards its open end and has substantially no internal structure so as to be intimately stackable with other substantially identical outer tanks for its entire length. The inner aeration chamber generally increases in diameter from a first end to a second opposing end and has substantially no internal or external structures projecting away from the walls of the aeration chamber intermediate the first and second end, so as to be intimately stackable with other substantially identical aeration chambers for its entire length. Transportation of a plurality of wastewater treatment systems is efficient because of the stackability of the component parts. The system may also include a cover 15 adapted to close the open end of the outer tank. The system can also include a draft tube 25 with a diffuser assembly (27, 28, Fig. 3).

Title: System for allocationg fluid from multiple pumps to a plurality of hydraulic functions on a priority basis
Filed: 2012-03-15
Abstract: A valve assembly has a flow summation node coupled to a displacement control port of the first pump. Each valve in the assembly has a variable metering orifice controlling flow from an inlet to a hydraulic actuator and has a variable source orifice conveying fluid from a supply conduit to a flow summation node. The source orifice enlarges as the metering orifice shrinks. Each valve includes a variable bypass orifice and the bypass orifices of all the control valves are connected in series forming a bypass passage between a bypass node and a tank. The bypass node is coupled to the flow summation node and receives fluid from a second pump. At each valve, a source check valve conveys fluid from the supply conduit to the inlet and a bypass supply check valve conveys fluid from the bypass passage to the inlet.

Title: Method and apparatus for washing or for washing and sterilizing articles
Inventor: BARAN WALTER JOHN
IPC: A61L2/06
Filed: 1979-12-24
Granted: 1984-05-30
Abstract: Decontamination washing or washing and biocidal treatment of articles, including washing and sterilizing of surgical instruments is effected in a single chamber (10). Air is delivered under pressure for injection at the bottom of the chamber (10) through a plurality of inlets (52 to 58) positioned to provide interaction of their horizontally oriented discharges including formation of turbulent vortices. Upward movement of air creates vertically oriented cleaning turbulence. Spray means are provided to remove loose soil before washing and to remove soil separated by washing. Drainage removal of soil from the chamber is verified by a drain probe. Steam sterilization at pressures above atmospheric provides for sterilization at temperatures of 120 DEG C and higher.
