Abstract: SIMULATED SPUN-LIKE BULKED YARN     ABSTRACT OF THE DISCLOSURE      A method for producing a spun-like yarn simulating a staple yarn is described wherein continuous filament yarn is produced which has characteristics similar to a staple spun yarn.  The unusual continuous filament yarn produced is made by a texturing process which involves the crimping of a continuous synthetic yarn followed by overfeeding to an air bulking means and thence to heat setting means.  The preferred method utilizes false twist texturing of synthetic filaments such as polyester, nylon, cellu-lose acetate or cellulose triacetate and mixtures thereof with an air bulking jet interposed to act on the false twist textured yarn while it has a high residual torque and subsequently decaying said torque.

Abstract: Abstract of the Disclosure A method and apparatus are disclosed for measuring the amount of characteristic light produced by a process to be monitored.  Light in a waveband characteristic of the process is measured.  Light in nearby non-characteristic wavebands is also measured and used an in indication of the amount of background light in the characteristic waveband.  The amount of background light is subtracted from the total amount of light in the characteristic waveband, and the result is a measurement of the intensity of light produced by the process.  An example of the embodiment applies the invention to the measurement of sodium light produced by burning sodium.

Abstract: ABSTRACT          In its most preferred embodiment the invention relates to a water navigable vessel, having ice-breaking means comprising an ice-riding, forward portion, e.g. bow structure and ice-gripping, pulling or dragging means preferably rotatable screw means, attached to said ice-riding portion of said vessel.          Said ice-gripping means is in a cooperative relationship with the vessel's icebreaking bow structure whereby, when said vessel is positioned in an ice-covered body of water said ice-breaking means will break said ice in flexure when the ice-gripping means are activated (e.g. screw means are rotated), thereby permitting either retention of position of said vessel or movement of said vessel within the ice milieu.          The screw means have ice-cutting flights (blades) and are journaled in a preselected generally parallel alignment with the exterior of said bow to allow the exterior edge of the helical blades of said screw means to pressingly contact the top of said ice. When the screw means are rotated, the blades form groves within the top of said ice layer thereby interacting with and gripping said ice layer thus translating the rotational energy of said screw means into a generally horizontal, (longitudinal) tractional force which pulls or drags the bow of said vessel forward and over said ice layer and, thereby, utilizes the mass of said bow to impart a downward gravita-tional force upon said layer of ice to cause it to fail flexurally.          In effect the bow rides up over the ice due to the assistance of the screw means. The vessel can optionally be aided in its movement over the ice layer with additional propulsion means besides said pulling or dragging means.  These means can be propulsion means located either intrinsically with the vessel, or extrinsically to the vessel or both.     Other embodiments of the invention include use of ice-resistant structures having screw means mounted in a substantially vertical position on one or more substantially, vertical members to protect said member against damage by ice moving at an approximately 90° angle to said member.

Abstract: RESINOUS REACTION PRODUCTS Resinous reaction products wherein the hydrohalide salt of a polyamine is condensed with an epihalohydrin pro-vides improved wet strength and improved dry strength to cellulosic substrates such as paper, paperboard, and the like. It has been found that the wet strength and dry strength of paper products can be significantly improved by using a resinous reaction product resulting from the removal of halide ions from the polyamine hydrohalide salt before it is condensed with an epihalohydrin.

Abstract: ABSTRACT OF THE DISCLOSURE         A damper for a lever mechanism wherein a lever beam is mounted for pivotal movement about a pivot axis.          The damper includes a rigid enclosure formed with a cavity having fluid contents therein, and a paddle extends through the opening and into the fluid.  A flexible seal extends from the opening in the enclosure and supports the paddle in the fluid.  The flexible seal functions as a variable pivot for controlling the pivotal movement of the paddle within the cavity.  The arrangement is such that the damper enclosure can be fastened to a base of the lever mechanism and the free end of the paddle is attached to the lever mechanism so that the pivot axis of the lever mechanism extends through the flexible seal, wherein the paddle, in response to the movement of the lever mechanism, pivots about the pivot axis of the lever mechanism since the damper mechanism is a sealed unit, it can be used in any orientation.  The mass of the paddle can be selected and the center of gravity located relative to the pivot axis so that a static balance of the lever mechanism can he achieved wherein the operation of the entire transducer is sensitive to position or orientation.

Abstract: ABSTRACT OF THE DISCLOSURE:          A method of displacement bleaching digested, washed cellulosic pulp.  Pulp is continuously passed through successive bleaching stages, each bleaching stage having a displacement-extraction loop.  Bleaching chemical is added to the pulp in each bleaching stage to effect bleaching.  Minimization of chemical con-sumption within an oxidative displacement-extraction loop is important in displacement bleaching, and this is accomplished by controlling the reaction rate with temperature.  The temperature in a given oxidative displacement-extraction loop (i.e. with Chlorine dioxide bleaching chemical) is maintained in the range of about 120°F to less than 160°F, preferably about 135 - 140°F.          A 0.5% net savings within the given displacement-extraction loop may be effected with pulp of the same quality, and a corollary savings in energy is also effected.

Abstract: AIR WASHER PARTICULARLY FOR PAINT SPRAY BOOTHS Abstract of the Disclosure Air or other gases containing contaminants or requiring treatment are moved into at least one substantially continuous sheet of treating liquid at the entrance to a stream-line flow passage. A nozzle mounted adjacent the entrance end of the flow passage forms one or more substantially continuous solid sheets of treating liquid covering the entrance to the passage. The passage has a convex throat and an exit smaller than the entrance so that the gas and treating liquid entrained therein move through the passage at an accelerating velocity with smooth, non-turbulent, unidirectional flow, and are dis-charged therefrom with no discernible turbulence or splashing. The gas and the treating liquid are discharged from the flow passage into an eliminator chamber of large volume, whereupon the treating liquid and any entrained contaminants drop out of and are separated from the gas. The invention is particularly adapted to paint spray booths for removal of paint overspray from the booth ventilating air prior to discharge of the air to atmosphere.
