Abstract: ABSTRACT Relatively rotating face ring-type shaft seals especially useful for sealing the shaft bearings and lubricant chamber of mud motor driven downhole drill rigs, have a plurality of telescoped annular seal rings slidably mounted in an annular carrier element and rid-ing over the radial face on a face ring to define a sealed intermediate chamber therebetween.  This inter-mediate chamber may be filled with lubricant.  Either the telescoped rings or the face rings rotate with the shaft.  Biasing means, such as a plurality of springs, load end faces on the seal rings against the radial face of the face ring.  Pressure transmission means, such as pistons, O-rings, or the like, mounted in either the carrier element or the face ring, are loaded by the ambient media pressure, such as drilling fluid, to maintain pressure in the intermediate chamber responsive to the pressure of the ambient media.  When the areas of the pressure transmission means exposed to ambient pressure and to intermeidate chamber pressure are equal, a zero or negligible pressure differential will be maintained across the outer telescoped seal ring to prevent the ambient media, which is frequently quite abrasive, from entering the outer sealing ring interface. The inner telescoped seal ring serves an an auxiliary back-up face ring seal for the protected bearing chamber. Since the abrasive media being sealed does not enter the interfaces of the rings, the end faces of the inner and outer sealing rings riding on the face ring can be reduced or narrowed to a minimum and coated with a hard facing material such as tungsten carbide.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved method for removing particles en-trained in air, particularly moisture particles which may contain salt or other contaminating matter. The im-proved method is particularly useful in connection with marine applications for removing moisture particles from air being introduced to a gas turbine on a marine vehicle The improved method includes the steps of passing the air at a velocity greater than 20 ft. per second through an inertia separating device for inertially removing at least a portion of the larger sized particles in the air to provide partially processed air, and then passing the partially processed air at a velocity which is greater than a predetermined velocity through an impact filtering pad for removing particles entrained in partially processed air. The impact filtering pad comprises at least one layer of a plurality of fibers, each of the fibers having a diameter greater than .001 inches and less than .006 inches, and the ratio of total surface area of the fibers in the pad to the volume of the pad being greater than 45 ft.-1  and less than 1400 ft. -1. The predetermined velocity at or above which the partially processed air is passed through the impact filtering pad is greater than 20 ft. per second and is chosen according to the diameter of the fibers in the pad so that coalescense of moisture particles captured by the pad is minimized.

Abstract: WATER  SOLUBLE FILMS OF POLYVINYL ALCOHOL AND POLYVINYL PYRROLIDONE         ABSTRACT OF THE DISCLOSURE           Films which are rapidly soluble in cold and warm water are formed from blends of water soluble polyvinyl alcohol (partially hydrolyzed polyvinyl acetate) and polyvinyl pyrrolidone.     The polymers are compatible and form homogeneous mixtures from which clear, transparent, non-tacky, easily handleable, mechani-cally strong films can be formed.  The films are stable at both low and high humidity conditions, i.e., the films do not become brittle or tacky and retain their high rates of dissolution in water even after being stored in low or high humidity environments at both high and low temperatures.  Further, improvements are achieved by incorporating a plasticizer into the polymer blend. The films are also heat sealable and biodegradable and are useful as packaging, particularly for packaging dry detergents and similar water soluble commodities.

Abstract: ABSTRACT OF THE DISCLOSURE          A multistage process for permanent hair shaping e.g. waving, in which prior to and/or after winding the hair on rollers it is treated with a liquid hair-keratin-reducins permanent shap-ing agent.  This liquid, weakly shaping-efficient permanent shap-ing agent can shape the hair in the region of the hair ends without damaging the hair ends during the reaction time.  A consistent, hair-keratin-reducing permanent shaping agent, which has a viscos-ity of 50 to 5000  mPa-s at 30°C, preferably 100 to 500  mPa.s, and a more intense shaping efficiency as compared with the liquid permanent shaping agent, is then applied.  The consistent perman-ent shaping agent shields the hair externally and thus prevents the admission of atmospheric oxygen on the one hand and the escape of a volatile alkalizing agent, as for example, ammonia, on the other.  Furthermore, a good shaping effect on the hairline is attained by the higher shaping efficiency of the consistent perman-ent shaping agent without the danger of overcurling the hair ends.          After an adequate reaction time the hair is rinsed and then treat-ed with a solution having an oxidizing effect.

Abstract: Bundling of objects using a harnessing device with a locking head and a strap with teeth having a surface with a profile that is controlled by stretching so that if the teeth have an initial profile formed by rectilinear segments, the stretching converts the rectilinear segments to, for example, curved segments. The locking head contains a pawl or tang that engages the teeth of the strap by wedging. One or more wedging teeth are desirably located on the locking tang as well. A further tooth to promote locking is desirably included in the locking head. The strap is advantageously molded of stretch reorientable material which is subsequently stretched to control the profile of the teeth which are engaged by the locking tang and head. The teeth are spaced on the strap to permit use of the teeth near the head for the harnessing of small bundles. The pawl is provided with specified pivot points for both the insertion and loading of the strap in the head.

Abstract: ABSTRACT      A computer architecture is disclosed which permits intersegment program calls with associated selective allocation of data segments of varying lengths.  The calling program controls selective allocation of segments to the called program but the called program controls the lengths of the segments being allocated. In this way, recursive calls to the same program cannot affect the function or data of other programs or of the same program in a previous call.  Also allocation of data segments can be postponed until execution resulting in more flexible execution of programs written without knowledge of the details of other co-executing programs.

Abstract: DIGITAL SWITCHING OVER PAM BUS SYSTEM            Abstract In a PAM bus switching bus which normally handles analog voice signals, the different DC offsets caused by the different buffing, summing and distribution amplifiers cause no ill effects because DC voltages are not passed by the remainder of the support elements.  However, when it is attempted to switch logic level DC signals through such a PAM bus network, the DC offset which is an indeterminate function of the particular switching path established, makes it impossible to establish a uniform slicing level. in the illustrative embodiment a uniform slicing level is achieved by clamping the summing bus of the PAM system during a preamble of the time slot, measuring the offset on the distribution bus and then applying the measured offset to compensate the distribution bus during the remainder of the time slot when the actual data signal is allowed to be applied to the summing bus.
