Abstract: ABSTRACT   This invention relates to a novel process for preparing novel foamed polymeric products having uniform cell structure which comprises mixing a non-volatile polar substance, a foaming agent and an ionic polymer, said non-volatile polar substance being a preferential plasticizer for said ionic polymer and said foaming agent characterized as being sparingly soluble in said ionic polymer, subjecting said mixture to an elevated temperature and pressure whereby said foaming agent and said non-volatile polar substance are impregnated into said ionic polymer, and foaming said impregnated ionic polymer.  Preferably the ionic polymer comprises from about .2 to 20 mole % pendant ionic groups, especially sulfonate groups.  In a preferred embodiment of the instant invention a sulfonated polystyrene polymer is admixed with a non-volatile polar compound and a foaming agent which is characterized as having a solubility parameter of less than 7.9 and a boiling point of less than 100°C, under elevated pressure and temperature whereby said foaming agent and said non-volatile polar compound are impregnated into said sulfonated polystyrene polymer and the resultant mixture foamed at atmospheric pressure ant at a temperature of at least 105°C.  Upon cooling, a low to moderate density foam of uniform cell structure is formed which can be reprocessed by admixing with a low boiling solvent for polystyrene and a non-volatile polar substance, removing said low boiling solvent and repeating the above foaming process.

Abstract: ABSTRACT OF THE DISCLOSURE         An effective amount of a vinylbenzyltrialkylammonium salt, prepared from a vinylbenzyl halide and a tertiary amine, is polymerized with various other monomers to afford stable latex polymers which have the latex stabilizing surfactant incorporated into the polymer backbone.  The use of a vinyl-benzyltrialkylammonium salt lessens or avoids the usual problems associated with the conventional anionic, nonionic or cationic emulsifiers employed in aqueous polymerizations. The copolymers prepared with the quaternary ammonium compounds are useful as sizing agents, as extender/binders for cationic water repellents; in addition, the polymers are depositable on pulp without requiring any deposition aids or defoamers.

Abstract: ABSTRACT OF THE DISCLOSURE                Electrophotographic copying apparatus having a multiple development capability for more completely developing and, hence, improving the quality of images which contain extended solid areas.  This multiple development capability is attained by designing the development station in such a manner that the latent electrostatic image to be developed and the developer mixture will move through the development station at a sub-stantially identical velocity as distinguished from conventional system in which the developer passes through the development station much faster than the image.  By matching the velocities of the image and the developer, degradation of the developed, or partially developed, image by the rubbing or sweeping of the carrier beads across the image will be substantially eliminated, and, accordingly, multiple development becomes possible.  The sub-stantial matching of velocities is preferably accomplished by significantly reducing the width of the gap between the latent image bearing medium and the development plate through which the developer falls.  This increases the density of developer in the gap and the degree of developer agitation and, hence, causes it to fall much slower while still ensuring an adequate supply for effective development of all areas of the image. With a system designed in this way, copies having a quality equal or superior to those obtainable with conventional systems can be achieved with a single development step and at speeds com-parable to those available in todays high speed machines.  When, however, the image to be developed contains large extended solid areas. any needed number of additional development cycles can be selectively carried out to better develop such images and. hence, provide superior quality copies.

Abstract: METHOD AND APPARATUS FOR MAKING AN     ECCENTRIC LOCKING COLLAR     ABSTRACT OF THE DISCLOSURE     The invention contemplates low-cost and improved manufacture of an eccentric locking collar, as for use in securing a bearing ring or the like to a shaft.  The locking collar is made by cold-forming a cylindrical metal blank with an eccentric cylindrical recess at one end and with a concentric cylindrical recess at the other end.  A coining tool having the desired locking surface profile is inserted into the eccentric bore and is driven in axial compression causing blank material to flow or extrude around the profile.  Thereafter, a punching operation completes definition of the concentric cylindrical bore which is ultimately to accommodate assembly to a shaft, and finishing steps are performed, such as set-screw adapting and tumbling.

Abstract: ADAPTIVE CONTROL SYSTEM USING POSITION FEEDBACK     ABSTRACT OF THE DISCLOSURE    A control computer produces a position error signal in accordance with the difference between the desired position of a controlled device and the actual position of the controlled device.  The position error signal is amplified and compensated to produce a series of discrete control pulses of controlled but variable duration which regulate a servo actuating system connected to the con-trolled device so as to reposition the controlled device to the desired position.  The servo actuating system is a simple on-off integrating valve which does not depend on feedback or other techniques to regulate the position of the controlled device in response to the control pulses from the control computer.  Instead, the gain of the position error signal is varied during each cycle in an adaptive manner as a function of the measured change in position of the controlled device in response to the control pulse during the last previous cycle, and the next control pulse is accordingly generated as a function of the response of the entire control system during that previous cycle.

Abstract: Abstract of the Disclosure A method of protecting power transmission lines is, according to the invention, based on the comparison between the actual quantities of current and/or voltage at the beginning of the protected section of a power transmission line and the same quantities of current and/or voltage calculated by means of current and voltage paramet?rs at the end of the protected section providing there are no faults in this section. In apparatuses for realization of this method the voltage and current at the end of the protected section are multiplied in symmetrical components multipliers by respective coefficients of an equivalent four-terminal network substituting for the protected section and summed up. If there are no faults in this section, this calculated sum is equal to the respective electrical quantity at the beginning or the protected section. The electrical quantity measured at the beginning of the section is transmitted along a communications channel to the end of the section, where it is compared in a special unit with the respective calculated quantity. When there appears a fault in the protected section, the equation of the compared quantities is upset and the effector of the apparatus operates. The proposed apparatus permits protection of conventional, long-range and adjusted power transmission lines of high and superhigh voltage.
