摘要： A computer system used with special input hardware for providing the benefits of computerization to handwritten as well as keyboard entered information to meet a wide spectrum of commonly-occurring, written information processing needs. The input hardware consists of a transparent digitizing tablet mounted atop a flat panel display screen such that a user can handwrite directly upon the display screen with an attached pen. Application program functions include appointment documentation and work scheduling, handwritten or text file creation and manipulation, author-to-typist liaison functions for document production, handwritten annotation to text, handwritten note creation from text, and text document creation from handwritten source material.

摘要： A catalyst system is produced by first forming a chromium catalyst on a predominantly silica support, activating in an oxygen-containing ambient and thereafter subjecting the thus activated composition to carbon monoxide reduction. The resulting reduced supported chromium catalyst composition is then precontacted with a cocatalyst selected from trialkyl boron compounds and dialkyl aluminum alkoxide compounds, preferably triethyl borane and thereafer contacted with ethylene. This results in a catalyst system which produces comonomer in situ so as to give tough, flexible ethylene copolymers from an essentially pure ethylene feed.
摘要翻译：通过首先在主要是二氧化硅载体上形成铬催化剂，在含氧环境中活化，然后使由此活化的组合物经一氧化碳还原来生产催化剂体系。然后将所得的还原的负载型铬催化剂组合物与选自三烷基硼化合物和二烷基铝醇盐化合物，优选三乙基硼烷并且与乙烯接触的助催化剂预接触。这导致了一种催化剂体系，其在原位产生共聚单体，从而从基本上纯的乙烯进料中提供坚韧的，柔性的乙烯共聚物。

摘要： A valve structure including a valve body defining a valve chamber, a pair of annular inlet and outlet seal members, and a tapered valve member journaled in corresponding tapered sealing surfaces in the inlet and outlet seal member. Passages communicate respectively between a fluid source and the inlet passage, the outlet passage and the valve chamber. The maximum diametral dimensions of the valve passage through the valve member at its point of communication with the tapered surface of the valve member is less than the minimum width of the sealing surfaces of the seal members along the path traced by the valve passage as the valve member is rotated. A method of controlling passage of material through such a valve structure is also disclosed.

摘要： A method for continuous production of block copolymers having a block of propylene homopolymer and blocks of polymer of ethylene. The block copolymers produced thereby. In a first stage a first reaction mixture containing a polymer of ethylene is produced with continuous transfer of a portion of this reaction mixture along with propylene monomer and a catalyst modifier into a second stage in which a block copolymer having a block of propylene homopolymer and blocks of polymer of ethylene is produced. In preferred embodiments the polymer of ethylene is ethylene homopolymer and/or ethylene-propylene random copolymer.

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.
