摘要： A whirling banner having a handle, an axle portion disposed on the handle, a banner, and a radial arm having means for attaching the banner at one end and means for rotatingly supporting the axle at the other end. The radial arm is preferably constructed of two halves folded over one another, defining a fold at one end. At the end opposite the fold, the radial arm has a barb on one half for piercing and attaching the banner. The barb engages a hole on the other half and holds the two halves of the arm together. The end of the arm closest the fold has a hole passing through both halves for rotatingly supporting the axle. The axle has a hub for keeping the axle in the hole while allowing the arm to freely rotate about the axle.
摘要翻译：具有把手的旋转横幅，设置在手柄上的轴部，横幅和具有用于在一端附接横幅的装置的径向臂，以及用于在另一端旋转地支撑轴的装置。径向臂优选地由彼此折叠的两个半部构成，在一端限定折叠。在与褶皱相反的一端，径向臂在一半上具有倒钩，用于刺穿并附接横幅。倒钩与另一半的孔接合，并将臂的两半保持在一起。最靠近折叠的臂的端部具有穿过两个半部以旋转地支撑轴的孔。轴具有用于将轴保持在孔中的轮毂，同时允许臂绕轴自由旋转。

摘要： A highly bulked kaolin pigment is prepared by mixing a small but effective amount of a water-soluble cationic polyelectrolyte flocculant with a kaolin clay pigment in the presence of water to prepare a bulked clay pigment product. Upon dewatering, the resultant polyelectrolyte treated clay product can be dispersed to form high solids clay-water slurries useful in making aqueous coating colors suitable for manufacturing coating lightweight publication papers or the pigment can be used as a filler for paper webs.

摘要： The present invention provides oil-soluble, polymeric surface-active agents which are polyimide-amine salts of styrene-maleic anhydride copolymers having pendant tertiary amine groups containing a salt-forming tertiary nitrogen atom neutralized to the extent of at least about 75 percent with mono-carboxylic acids for instance having an aliphatic chain of at least about 8 carbon atoms. The salts of this invention exhibit the property of lowering the surface tension at oil-water interfaces. The polyimide-amine salts can also contain mixed imides resulting from the reaction of dialkylaminoalkylamines and monoalkyl amines or mixed imide-amides resulting from the reaction of dialkylaminoalkylamines and dialkylamines. This invention also provides oil compositions containing mineral oil and the oil-soluble, polymeric surface-active polyimide-amine salts, with or without water. These compositions are useful, for instance, as hydraulic fluids, jet fuels, electrolyte-containing oils, anti-wear lubricating oils, diesel fuels, and gasolines.
