  • Patent number: 6591864
    Abstract: A pressure (1) release valve is disclosed ideally for use on petrol tankers which can rollover in an accident. There is a requirement for such valves both to become sealed in the event of a rollover to prevent the escape of volatile and flammable fluid from within the tanker, and also to allow for the venting of gas above the fluid within the tanker under normal operating conditions. The valve comprises a movable plunger (24) and a fixed seat (32) which can move axially towards and away from each other to open and close the valve. One or other of valve seat and plunger is provided with magnetic inserts (23), while the alternate component is ferromagnetic so that magnetic attraction betwixt the two components acts to bias the valve towards a closed condition.

  • Patent number: 6586461
    Abstract: Farnesyl diphosphate analogs, specifically the 3-substituted alcohol precursors of the diphosphate analogs, 3-allylfarnesol and 3-vinylfarnesol, are potent inhibitors of mammalian protein fanesyltransferase (FTase). 3-allylgeranylgeraniol is a highly specific cellular inhibitor of protein geranylgeranylation (GGTase I). Furthermore, these compounds are able to efficiently block the anchorage-dependent growth of ras transformed cells. While 3-allylfarnesol inhibits protein farnesylation in situ, 3-vinylfarnesol instead leads to the abnormal prenylation of proteins with the 3-vinylfarnesyl group. In a similar manner, treatment with 3-allylgeranylgeraniol inhibits protein geranylgeranylation while 3-vinylgeranylgeraniol restores protein geranylgeranylation in cells.

  • Patent number: 6521112
    Abstract: A method of controlling the content of a chemical bath includes the steps of: determining a replenishment condition for the chemical bath; defining a unit of the replenishment condition; establishing a pacing factor corresponding to a replenishment volume of a replenishment medium per unit of the replenishment condition; and defining a replenishment threshold corresponding to the product of a predetermined number of the defined units of the replenishment condition and the pacing factor. The rate of continued replenishment of the predetermined constituent of the chemical bath is determined in response to the replenishment condition, which may be elapsed time, ampere-hours (or coulombs), number of product loads, product surface area, or line speed over time. The method replenishes constituents as they actually are consumed. It also prevents depletion (or buildup in the case of decanting a by-product) and the associated time delay related to detection and correction.

  • Patent number: 6518637
    Abstract: Device quality, single crystal film of cubic zinc-blend aluminum nitride (AlN) is deposited on a cubic substrate, such as a silicon (100) wafer by plasma source molecular beam epitaxy (PSMBE). The metastable zinc-blend form of AlN is deposited on the substrate at a low temperature by a low energy plasma beam of high-energy activated aluminum ions and nitrogen ion species produced in a molecular beam epitaxy system by applying a pulsed d.c. power to a hollow cathode source. In this manner, films having a thickness of at least 800 Å were produced. The lattice parameter of as-deposited films was calculated to be approximately 4.373 Å which corresponds closely to the theoretical calculation (4.38 Å) for cubic zinc-blend AlN. An interfacial layer of silicon carbide, specifically the cubic 3C—SiC polytype, interposed between the epitaxial film of zinc-blend AlN and the Si(100) wafer provides a template for growth and a good lattice match.

  • Patent number: 6405419
    Abstract: An arrangement for exercising (or burnishing) the intake and exhaust valves in the cylinder head of an internal combustion engine employs a plurality of out-of-phase eccentric cams coupled to a source of rotatory motion. The eccentric cams engage with respective linear drive arrangements that are urged into out-of-phase reciprocation with respect to each other. The linear drives urge the valves into repeated open and closed states where, in combination with valve rotators, burnishing of the sealing portion of the valves with the valves seats to improve the seal therebetween is effected. The use of eccentric cams to effect linear reciprocating motion achieves control over both directions of movement of the linear drive arrangements. The cylinder head is maintained in fixed relation to the linear drive arrangements by a hydraulic, pneumatic, or other form of ram, the ram also creating a test chamber.
