摘要:
Two pairs of complementary semi-circular elements are arranged one above the other with the lower members stationary and the upper members movable vertically downwardly by any suitable type of press to straighten deformed tubular front axle beams, for example, those used on present types of Volkswagens.

A spent gun cartridge case is re-sized for its full length by placing it on a threaded support and then threadably joining the support-case assembly with a die. The case is freely supported on a thrust bearing so that the case rotates with the die as the members are threaded together. Alternately, the case and die are startingly joined and the resultant assembly threaded onto the support.

A material dispense tip includes an elongated hole in an elongated neck that extends from an input end of the neck to an output end of the neck. The hole at the output end of the neck has a first diameter. The output end of the neck is positioned against a die surface. A punch is inserted into the hole at the input end of the neck. An external force is applied to the neck to cause the output end of the neck to be deformed under compression by the die surface, to reduce the diameter of the hole at the output end of the neck from the first diameter to a second diameter that is less than the first diameter.

摘要:
A press mold includes an inner punch (23), an intermediate punch (24) disposed along an outer periphery of the inner punch (23) and having an intermediate punch inclined portion (24a) at a leading end, an outer punch (25) disposed along an outer periphery of the intermediate punch (24), and a die (27) having a die inclined portion (27a) facing the intermediate punch inclined portion (24a), central axes (20) of all of which are coaxially disposed. While a bottom portion of a bottomed container (22) is constrained by the inner punch (23) and the die (27), an end portion of the bottomed container (22) is pressed by the outer punch (25), and the intermediate punch (24) is moved in a direction opposite a direction in which the outer punch (25) is pressed, whereby a bottomed container inclined portion (22a) of the bottomed container (22) sandwiched by the intermediate punch inclined portion (24a) and the die inclined portion (27a) is thickened.
摘要:
The disclosure includes a polymerization process and an olefin polymerization system. A polymerization product is produced, a vapor phase is recovered from the polymerization product, the vapor phase is fractionated in a first column to yield a fraction stream, and the fraction stream is fractionated in a second column. A first stream of the second column, which comprises a diluent, can be recycled to a first polymerization reactor. A second stream of the second column, which comprises olefin monomer, diluent, and hydrogen, can be recycled to a second polymerization reactor. Comonomer may be recycled from the first column to the first polymerization reactor, the second polymerization reactor, or both.

Apparatuses, related components, and methods for expanding capacity of fiber optic housings are disclosed. A fiber optic apparatus comprising an attachment housing comprising a side, a top, and a bottom defining an attachment interior chamber configured to support at least a portion of fiber optic equipment is provided. The attachment housing is tool-lessly, and by other than external fasteners, configured to removably attach to a fiber optic housing comprising a housing interior chamber configured to support fiber optic equipment to couple the attachment interior chamber and the housing interior chamber, which may be done by means of snap attachments integral to at least one of the attachment housing and the fiber optic housing. One or more optical components, which may include, without limitation, one or more splitter trays, fiber optic jumper slack storage, and one or more strain relief devices, may be mounted within the attachment housing.
摘要:
The present invention discloses a method for transforming a single reactor line into a double reactor line wherein the existing single reactor line is equipped with a flash tank for separating the solid polymer product from the flash vapor and wherein the vapor is sent to a system of at least two separating columns allowing the separation of its constituents into monomer, diluent and comonomer.
摘要:
A method of reducing the volume of a boiling water reactor fuel channel for storage in which the fuel channel is sealed with an outer sleeve that is closed at its upper and lower ends. The sleeve, which is made of a malleable metal is then laterally compacted and sheared into segments suitable for transport and/or storage.
摘要:
A pallet includes a platform and a plurality of support assemblies located at multiple positions on the platform. One support assembly is associated with each location of the component to be supported. Each support assembly has a linkage assembly to support and enable movement of a support element to position the support element in a desired location for each version of a component. A support element locking mechanism on each support element allows for selectively preventing vertical movement of the support element relative to the linkage assembly. Additional locking mechanisms associated with the linkage assembly prevent movement of the linkage assembly relative to the base.
