    • A method for making an oxidized cellulose product from a cellulose material is disclosed. The method involves oxidizing a cellulose material into an oxidized cellulose product, comprising treating the cellulose material with a hypochlorite solution having an active chlorine content of between about 4 and about 6%, at a pH exceeding 9.5 and at a temperature, and for a time, effective to convert the cellulose material into the oxidized cellulose product; filtering the oxidized cellulose product; and washing the oxidized cellulose product with an antichlor agent such as sodium thiosulfate to remove chlorine and to raise the oxidized cellulose product to a neutral pH.The oxidized cellulose product may be used to form films, dispersions, gels, as carriers, for pharmaceuticals, cosmetics and other products.
    • 公开了一种从纤维素材料制备氧化纤维素产品的方法。 该方法包括将纤维素材料氧化成氧化的纤维素产品,包括用活性氯含量为约4至约6%的次氯酸盐溶液处理纤维素材料,pH值超过9.5,并在一段时间 有效地将纤维素材料转化成氧化纤维素产品; 过滤氧化纤维素产品; 用硫代硫酸钠等抗氯剂洗涤氧化纤维素产品,除去氯,使氧化纤维素产物升至中性pH。 氧化纤维素产品可用于形成药物,化妆品和其它产品的膜,分散体,凝胶,载体。

    • A connector assembly (10) having an all plastic retention system has a housing (16, 18) in which tines (40) extend from a surface (36) thereof axially along contact receiving passages (38, 58). Each split frustoconical tine (40) has two tine members (42, 44). A transverse rib (54) extends along a surface (36) of the housing between adjacent tine members (42, 44) of adjacent tines (40). Each tine member (42, 44) has a pair of vertical ribs (50) extending along the exterior surface thereof upward from the surface (36) of the housing and sharing a portion of its volume with the transverse rib (54). The vertical ribs (50) and transverse rib (54) promote flow of plastic into all regions of the mould during moulding and support a contact (52) upon insertion thereof. A contact (52) inserted from the rear face (34) causes tine members (42, 44) to move radially outward until a retention bead (72) passes through an orifice (48) then tine members (42, 44) return to an unbiased position and contact (52) is secured in the connector assembly (10) as retention bead (68) is positioned between an annular shoulder (74) and the ends (46) of tine members (42, 44).
    • 具有全塑料保持系统的连接器组件(10)具有壳体(16,18),齿条(40)从其轴向沿着接触接收通道(38,58)的表面(36)延伸。 每个分裂截头圆锥齿(40)具有两个齿构件(42,44)。 横向肋(54)沿着相邻齿(40)的相邻齿部件(42,44)之间的壳体的表面(36)延伸。 每个齿构件(42,44)具有一对垂直肋条(50),其沿其外表面从壳体的表面(36)向上延伸,并且与横向肋条(54)共享其一部分体积。 垂直肋(50)和横向肋(54)在模制期间促进塑料流入模具的所有区域,并在其插入时支撑触点(52)。 从后表面(34)插入的接触件(52)使得齿部件(42,44)径向向外移动,直到保持凸缘(72)穿过孔口(48),然后齿部件(42,44)返回到 无偏位置和接触(52)固定在连接器组件(10)中,因为保持凸缘(68)位于环形肩部(74)和齿构件(42,44)的端部(46)之间。
