    • A process for the production of sucrose-6-ester is disclosed. The process includes, in order, the steps of: (a) providing a first reaction mixture including sucrose, a reaction vehicle, and an organotin-based acylation promoter; (b) removing water from the first reaction mixture to afford a second reaction mixture that is substantially free from water; and (c) adding a carboxylic acid anhydride to the second reaction mixture to afford a third reaction mixture, thereby producing a sucrose-6-ester; wherein: during step (b), the removing of water includes distillation of water with the reaction vehicle using an apparatus supplying a heat flux of from 500 to 25,000 BTU/hrft2 (1577 to 78865 W/m2) selected from the group consisting of wiped film evaporators, agitated thin film evaporators, falling film evaporators and rising film evaporators.
    • 公开了生产蔗糖-6-酯的方法。 该方法按顺序包括以下步骤:(a)提供包含蔗糖,反应载体和基于有机锡的酰化促进剂的第一反应混合物; (b)从第一反应混合物中除去水,得到基本上不含水的第二反应混合物; 和(c)向第二反应混合物中加入羧酸酐,得到第三反应混合物,由此生产蔗糖-6-酯; 其中:在步骤(b)中,除去水包括使用提供500至25,000BTU / hrft2(1577至78865W / m 2)的热通量的装置与反应车辆蒸馏水,所述热通量选自擦拭 薄膜蒸发器,搅拌薄膜蒸发器,降膜蒸发器和上升膜蒸发器。

    • A connector includes a barrel defining a cavity. A front portion is configured to removably mate with the barrel. An electrically conductive elongated pin is positioned in the opening of the front portion and the cavity of the barrel. The pin extends through a distal end of the front portion, and the pin includes a back end for mating with an electrically conductive element. A grasping device defines an aperture therethrough for receiving the electrical element. The grasping device is disposed within the cavity of the barrel. The grasping device is in an engaged position when the barrel and the front portion are coupled for holding the electrically conductive element positioned within the aperture, and the grasping device is in a disengaged position when the barrel and the front portion are uncoupled.

    • An apparatus for opening and closing window blinds converts rotary motion about a vertical axis of a vertical rod into rotary motion about a horizontal axis of a horizontal member. A lever is attached to one end of the horizontal member. A drive gear is attached to an opposite end of the horizontal member. A driven gear is attached to a first end of a vertical member. The driven gear is operatively engaged with the drive gear. The vertical member is perpendicular with respect to the horizontal member. An adapter housing is attached to an opposite end of the driven gear and is used to attach a bottom end of the vertical rod thereto. All component parts are supported by a base member that is attached to a wall. Turning the lever rotates the drive gear which rotates the vertical rod and, accordingly, opens or closes the blinds.
