  • Patent number: 5769259
    Abstract: An end panel for a full-open end closure for a container comprising a rim portion, a removable central panel portion connected to the rim portion for detachment by an opening implement, an array of closely spaced push-in closure members dimensioned and spaced to receive the prongs of a standard domestic fork as the opening implement. The closure members are in a generally linear array adjacent the rim portion and the fork engages the openings defining the closure members and is levered against the rim to remove the central panel portion from the rim. Alternatively, the closure members are in a radial linear array extending towards the center of the central panel portion with the outermost closure member adjacent the rim portion so that the central panel portion can be conveniently levered from the rim portion without the need for a special opening implement.

  • Patent number: 4816090
    Abstract: A method of heat treating cold rolled steel strapping comprising rapidly heating the strapping to the dual phase temperature range at a rate of the order of 100.degree. C. per second, with little or more soaking, and rapidly cooling the strapping at a rate of the order of 1000.degree. C. per second to form a microstructure comprising a matrix of recovery annealed cold work ferrite containing martensite and carbides dispersed through the matrix. A heat treatment line for performing this method is described. A heat treated cold rolled steel strapping produced by the method is also described. The steel from which the strapping is made preferably has less than 0.2.degree. C. and includes Ti in the range 0.06 to 0.15% preferably about 0.08% and Nb in the range 0.02 to 0.05% preferably about 0.04%.

  • Patent number: 4701838
    Abstract: A method of handling, as bulk material, a substance which is one member of a class of multi-component substances includes subjecting successive test samples of the substance to a series of measurements which provide multiple data points which are influenced by at least one selected parameter and from which are determined the factor loadings for the respective test sample of each of multiple pre-determined abstract factors. Pre-determined regression coefficients are utilized to calculate from the factor loadings a predicted value for the selected parameter for the respective test sample. The predicted value is compared with one or more related set points, and the constitution and/or disposition of the substance is controlled in response to the outcome of the successive comparisons.

  • Patent number: 4695670
    Abstract: Process for conversion of a light olefinic feedstock into gasoline by contact with a zeolite catalyst, characterized in that the catalyst contains at least 0.5% of weight by a Group IA metal oxide, has an X-ray powder diffraction pattern (Co radiation) exhibiting the presence of ZSM-5 zeolite and characterized by a peak in the region 2.theta.=27.0.+-.0.2 which is greater in intensity than peaks at both 2.theta.=9.29.+-.0.2 and 2.theta.=10.25.+-.0.2 degrees.

  • Patent number: 3948415
    Abstract: This specification discloses improvements in easy-opening closures of the push-in type in which the closure member at least partly overlaps with the aperture surround to define the easy-opening closure. The improvement comprises forming the free edge of the closure member and the aperture surround with interengaging portions which at least substantially inhibit the movement of the closure member relative to the aperture surround. In one preferred form of interengagement the closure member is formed with an upstanding lip and the aperture surround is downwardly turned about said lip. In another form both the aperture surround and the closure member are formed with interengaging lips. In another form the aperture surround is grooved and the lip on the closure member engages the groove. In the last form the aperture surround is formed with a lip which is stamped into the closure member to key the two parts together.
