Abstract: A process for purifying vinyl acetate contaminated with acetic acid, coloration agents, water, and/or cations and anions. A first stage consists of removing acetic acid from a vinyl acetate feed by dehydrating a commercially-available anion exchange resin by means of azeotropic distillation and passing the feed through a bed of the dehydrated resin. A second stage can consist of removing coloration agents by passing the vinyl acetate feed through a bed of activated carbon. A third stage can consist of removing water by passing the vinyl acetate feed through a bed of desiccant. A fourth stage can consist of removing cations and anions by passing the vinyl acetate feed through separate cation exchange resin and anion exchange resin beds or through a mixed resin bed.

Abstract: A vibration damper of viscous damping type for damping low-frequency (10 to 20 Hz) vibrations has at least one subpassageway oblique to the axis of a main passageway. Since vortexes are generated around the main passageway as damping fluid passes through the subpassageway, the fluid can effectively reciprocate through the main passageway in response to pressure gradients induced by the vortexes, thus increasing the damping force generated as the fluid flows through the main passageway. Further, since the frequency at which the maximum flow rate, that is, the maximum damping factor can be obtained is determined on the basis of the dimensions of a passageway, the dimensions of the main passageway and the subpassageway are selected so as to match the maximum-flow-rate frequency of the subpassageway with that of the main passageway.

Abstract: In a cathode ray tube display system in which objects to be displayed are represented by digital signals, a technique is employed to reduce distortion caused by aliasing. The objects to be displayed are represented in a memory by transition specifications which represent the object to be displayed by defining the character of the edges of the object to be displayed. From the transition specifications, a video signal is generated and applied to the cathode ray tube display device to display the object represented by the stored transition specifications. The circuitry generating the video signal causes the video to change in steps across the width of a transition from the brightness prior to the edge to the final brightness of the other side of the edge with the width of the transition varying in accordance with the slope that the edge makes with the raster scan line.
