摘要： A novel process is disclosed for converting a polystyrene or polystyreneacrylonitrile latex emulsion into a novel product comprising a white, opaque pigment for use as a paper filler, a paper coating pigment, a paint pigment, or for any other application where optimum optical effects are desired. The process comprises the high shear mixing of a polystyrenecontaining aqueous emulsion with a swelling agent which penetrates the polymer or copolymer particle thereby causing it to swell, and then a final step for setting the particle in its swollen state. When using a partially water miscible swelling agent, the emulsion may be washed and filtered to remove the swelling agent from the particle thereby setting it in the swollen state, but for an essentially non-water miscible swelling agent, the emulsion need only be filtered and dried to set the swollen particles, and, where removal of the swelling agent is not necessary, the treated emulsion may be used without the filtering or drying steps.

摘要翻译： 公开了一种用于将聚苯乙烯或聚苯乙烯丙烯腈胶乳乳液转化为包含白色不透明颜料作为纸填充剂，纸涂颜料，涂料颜料或用于需要最佳光学效果的任何其它应用的新产品的新方法 。 该方法包括将含聚苯乙烯的水性乳液与膨胀剂进行高剪切混合，所述溶胀剂渗透聚合物或共聚物颗粒从而使其膨胀，然后是将颗粒置于其溶胀状态的最后步骤。 当使用部分水混溶性溶胀剂时，可以将乳液洗涤并过滤以从颗粒中除去溶胀剂，从而使其处于溶胀状态，但是对于基本上非水混溶性溶胀剂，乳液仅需要过滤， 干燥以设置溶胀的颗粒，并且在不需要去除溶胀剂的情况下，可以使用经处理的乳液，而无需过滤或干燥步骤。

摘要： Each one of a pair of pivot arms is pivoted at one end to a stationary support, the pivots being in vertically spaced relation. The free end of each arm carries a driven shaft journaled therein. The shafts are free floating and are disposed in vertically spaced relation with their axes in a common vertical plane. Each shaft carries a chamfering tool and a guide roller therefor arranged in close proximity. Biasing means yieldingly urges the free ends of the pivot arms towards each other so that their respective guide rollers and tools forcibly engage the top and bottom faces of a workpiece passed therebetween. The shafts are driven from a single motor common thereto, using pulley and elastic belt drive connections. A similar arrangement of pivot arms carries means for applying liquid stain to the surfaces chamfered by the tools.

摘要： The surfactants of this invention are phenolic-formaldehyde resins that have been sulfomethylated with from 1-13 moles of sulfomethylation per 1000 grams of the starting resin and further modified by reaction with up to 20 moles, preferably 0.25 to 10 moles, per 1,000 grams of starting resin of a blocking agent of the type X(CHR)m(CH2)nY, wherein X is a halogen, an activated double bond, epoxy ring or halohydrin, Y is a property group such as sulfonate, phosphonate, carboxylate or hydroxyl, R is another property group such as hydrogen, hydroxyl, mercaptan or amine, and n and m are integers from 0 to 5, with n to m being at least 1, to at least partially block the phenolic hydroxy group of the resin. The phenolic-formaldehyde resin may also be cross-linked to tailor its molecular weight and then treated with urea or ammonia, if desired.

摘要： A process is disclosed for treating tall oil fatty acids. The process comprises treating tall oil fatty acids with a bromineiodine catalyst to convert the linoleic acid portion to oleic and other acids. The catalyst is employed in an amount of 0.06 percent to 2.0 percent by weight fatty acids at a temperature between 400*F. and 550*F. for a period of time between 10 minutes and 6 hours. The bromine-iodine catalyst is used at a bromine to iodine ratio of between 1:1 to 5:1 parts by weight. Tall oil fatty acids treated with the bromine-iodine catalyst of this invention give fatty acids almost identical to fatty acids treated with iodine alone. The advantage of this process is that less iodine catalyst is used to accomplish equivalent results as with iodine alone.

摘要： A water resistant corrugated paperboard materail is prepared wherein the paperboard components (medium and liner or liners) are each coated on both sides with a thermoplastic film which acts as a water barrier and a water resistant adhesive for bonding the components together. The corrugated medium is also pre-treated with an internal size treatment to prevent edge wicking, and, for the purpose of corrugating the medium without deleteriously affecting the thermoplastic film, the corrugating rolls are preheated to a temperature slightly less than the melting point of the thermoplastic film while a lubricating material is simultaneously applied to either the corrugating rolls or the medium at the corrugating nip.

摘要： Coreless spools, alternately wound on two spindle mounted mandrels from a continuous web supply of thin sheet material, are jet propulsively ejected from the mandrels by pressurized fluid conducted thereto. Loose end portions of the completed spools are rewrapped about the spool body by bridging a gap between two conveyors and two air curtains.
