    摘要: In one embodiment of this invention a surface silicated alumina composition, as opposed to conventional silica alumina, is provided. Such composition may also be fluorided and/or phosphated or phosphited. The resulting compositions are broadly useful but are of particular applicability as supports for chromium olefin polymerization catalysts. In another aspect alumina is fluorided and used with hexavalent chromium catalyst and a co-catalyst or in the alternative with an organochromium catalyst. If desired the support in this embodiment can also be phosphated or phosphited. In another embodiment, aluminum phosphate is formed in the pores of alumina. In contrast with alumina catalyst supports of the prior art, the supports of this invention allow for the production of olefin polymers at high rates of productivity. Also novel high density ultrahigh molecular weight polymers are produced.

    摘要: A cylinder lock is mounted in an aperture in a panel by means of a retaining ring which has resilient teeth to grip a part of the lock housing which protrudes from the panel. A further ring defining a non-circular aperture is provided in the opening of the panel to co-operate with flats on the lock housing and prevent rotation of the housing in the panel. The lock comprises a main body portion and a hollow spigot projecting from the main body portion and a key receiving member disposed in the spigot wherein the spigot defines an opening at an open end of the spigot remote from the main body portion. The key receiving member defines a key slot which is adjacent the open end of the spigot. The main body portion overlaps a marginal portion of the panel adjacent the panel opening defined thereby and the spigot extends through the aperture from the main body portion and projects from the panel at a second side thereof.

    摘要: A vanadium dichloride-ether complex is carried on a porous support. This complex can be produced by either forming VCl.sub.2 and thereafter complexing the material with an ether or forming an ether complex with VCl.sub.4 or VCl.sub.3 and thereafter reducing the vanadium compound to VCl.sub.2. It is also possible to carry out the complexing reaction and the reduction essentially simultaneously. The resulting catalyst in combination with a cocatalyst is capable of giving high activity in olefin polymerization and demonstrates good sensitivity to molecular weight control agents, thus allowing the production of a broad spectrum of polymers so far as molecular weight is concerned.

    摘要: A fire extinguishing apparatus includes a structure defining a first chamber containing an electrically operable explosive device. The apparatus also has a piezoelectric cell capable of producing an electrical output in response to the impact upon the piezoelectric cell. The apparatus also has a container of nonflammable pressurized fluid in contact with the structure, and a mechanical detection mechanism with a thermal sensor for producing a mechanical force at an established temperature. The mechanical force produced by the mechanical detection mechanism is applied to the piezoelectric cell to produce the electrical output that actuates the electrically operable explosive device.
