  • Publication number: 20110126923
    Abstract: A valve assembly for a liquid storage tank, the storage tank having a wall, the assembly comprising: a pressure relief conduit; a gas inlet valve device having a gas inlet aperture through which gas may pass into the tank; and a gas outlet valve device having a gas outlet aperture through which gas may pass out from the tank, the inlet valve device and outlet valve device being arranged to control a flow of gas into and out from the storage tank, respectively, whereby a pressure of gas in the tank may be maintained between an upper pressure value being a value in excess of a reference pressure value by a prescribed amount and a lower pressure value being a value below the reference pressure value by a prescribed amount, the gas inlet and outlet apertures being provided in gaseous communication with the pressure relief conduit, the pressure relief of conduit being arranged such that gas flowing into or out from the storage tank by means of an operation of the value assembly is caused to pass through the condui

  • Publication number: 20060272502
    Abstract: The invention relates to a process for the removal of SO2, HCN and H2S and optionally one or more compounds from the group of COS, CS2 and NH3 from a first gas stream, which process comprises the steps of: (a) removing SO2 from the first gas stream by contacting the first gas stream in a hydrogenation zone with a hydrogenation catalyst in the presence of hydrogen to obtain a second gas stream; (b) removing HCN and optionally COS and/or CS2 from the second gas stream obtained in step (a) by contacting the second gas stream in a hydrolysis zone with a hydrolysis catalyst in the presence of water to obtain a third gas stream; (c) removing NH3 from the third gas stream by contacting the third gas stream in a NH3-removal zone with an aqueous acidic washing liquid to obtain an ammonium-comprising aqueous stream and a fourth gas stream; (d) removing H2S from the fourth gas stream by contacting the fourth gas stream in a H2S-removal zone with an aqueous alkaline washing liquid to obtain a H2S-depleted gas stream and

  • Patent number: 6320197
    Abstract: A method and device for treating cultivation products or a cultivation medium, for instance cultivated soil or a growth substrate, against micro-organisms, for instance nematodes. The cultivation products or cultivation medium to be treated are placed in an electric and/or a magnetic field and held therein for a certain minimum time.

  • Patent number: 4643723
    Abstract: A device for administering a liquid in a number of doses, such as insulin to a patient, comprising a piston (3) in a pump chamber (4), a cannula (5) being connectable to the pump chamber, a piston rod (14) connected to the piston and having an operating button (25), a valve (1) and a reservoir (2), wherein by retracting the piston (3), at the same time the reservoir is connected to the pump chamber (4) through the valve in order to fill the pump chamber and the valve is moved into the position for closing the connecting element (6) between the pump chamber and the cannula (5) and wherein, by moving the piston forward, at the same time the connecting element between the pump chamber and the cannula is connected through the valve to the pump chamber and the valve is moved into the position for closing the passage (7) between the reservoir and the pump chamber.

  • Patent number: 4547997
    Abstract: An adjustable tool mount positions a rotatable tool on a machine tool spindle by a central tool mount ring having a internal thread machined throughout. The thread engages a pin extending from the tool spindle, so that rotation of the assembly causes axial advancement of the tool mount. The tool mount is clamped and unclamped by a lock nut received on the tool mount which compresses a plurality of nested conical spring rings which are closely fitted to a counterbore within the tool mount and to the machine spindle. Compression of the spring rings tends to enlarge the ring outer diameter and tends to reduce the ring bore, thereby causing a secure frictional grip to be effected between the tool mount and machine spindle.
