Abstract: 9D-RG-13054-Payne/Hurko OPTIMUM TIME RATIO CONTROL SYSTEM FOR MICROWAVE OVEN INCLUDING FOOD    SURFACE BROWNING CAPABILITY  ABSTRACT OF THE DISCLOSURE           An optimized time ratio control system for a microwave oven including a food surface browning system.  The system is particularly useful  where the avialable power is insufficient to operate both the browning system and the microwave energy generating system at the same time, and where the browning system has a relatively high thermal mass.          A timing means is effective to establish successive time share cycles.          Each time share cycle includes both a long browner ON time interval during which the browning system is energized at its full rated power level and an alternating interval, with the time ratio therebetween under user control.  During the alternating intervals, the browning system and the microwave energy generating system are alternately ener-gized, with the time ratio therebetween under the same user control.  The overall relative apportionment to microwave cooking power is primarily determined during the alternating intervals with what is essentially duty cycle power level control employing power pulses of relatively short duration.  The overall relative apportionment to browner power is pri-marily determined by the time intervals between the long browner ON time intervals, which between intervals are actually the alternating intervals.          During those times during the alternating intervals when the browning system is energized, the browning system is at least kept warm.  To com-pensate for a reduction in this "keep warm" power as the relative appor-tionment to browner power is decreased during the alternating interval, such as by user control, the long browner ON time intervals are lengthened as the percentage of microwave power increases and the percentage of browning power decreases.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for producing petroleum from subterranean formations is disclosed wherein production from the formation is obtained by driving a fluid from an injection well to a production well.  The process involves injecting via the injection well into the formation an aqueous solution of lignosulfonate salt as a sacrificial agent to inhibit the deposition of surfactant and/or polymer on the reservoir matrix.  The process may best be carried out by injecting the lignosulfonates into the formation through the injection well mixed with either a polymer or surfactant solution and/or a micellar dispersion.  This mixture would then be followed by a drive fluid such as water to push the chemicals to the production well.  The surfactant solution comprises a mixture of petroleum sulfonate and an alkyl benzene alkoxylated sulfonate.  In another embodiment, the surfactant solution comprises sulfonated alkoxylated alkyl surfactants and/or alkyl benzene alkoxylated sulfonates.

Abstract: ABSTRACT OF THE DISCLOSURE     A composite building element suitable for use in floors, walls, or roofs of buildings has inner and outer wooden boards separated by and secured to an intermediate layer of foam plastic, with each of the boards including two portions connected along a central longitudinal joint.  The element also includes an elongated web member extending between the boards and having its edge portions secured to the boards at their longitudinal joints.  The web member provides sufficient strength for the building element to be used in floors or roofs, even when the foam plastic layer occupies the majority of the thickness of the building element.  The building element may be made to simulate a wooden building log and used in log-type buildings.  Since the foam plastic is light, the building element can be made in greater width than a solid wooden log and yet have similar weight.

Abstract: VISCOUS FLUID DAMPING SYSTEM     ABSTRACT OF THE DISCLOSURE      A damping system for damping relative rotation of a pair of members having confronting surfaces spaced apart by a primary gap or zone of capillary dimension, a viscous damping fluid in the gap contacting the confronting surfaces of said members and held in the gap by capillary attraction to provide a damping action upon rotation of the members relative to one another, the arrangement providing a non-migrating self-supporting viscous fluid damping system.  In a preferred embodiment of the invention, the confronting surfaces of the members defining the capillary gap or zone are in non-parallel relationship, for example, one of the confronting surfaces may be planar and the other conical wherein the rotational axis of the rotatable member is disposed on the point of the cone to provide a point contact bearing minimizing friction and centering the viscous damping material adjacent the axis of rotation to provide a more uniform controlled damping action.  Still another feature of the invention resides in the provision of a secondary capillary viscous fluid reservoir of slightly larger capillary dimension than the primary capillary zone between the members.  The reservoir serves to replenish any fluid lost in the capillary zone due to evapora-tion for example, and eliminates the criticality of metering a precise amount of viscous fluid to the primary zone initially.

Abstract: PATTERN DENSIFIED FIBROUS WEB HAVING SPACED, BINDER IMPREGNATED HIGH DENSITY ZONES, AND METHOD OF MAKING SUCH A WEB   ABSTRACT      A soft, pattern densified fibrous web such as a paper sheet which web generally comprises a relatively low bond, high bulk, vaulted field and a patterned array of spaced zones of relatively high fiber density, at least a substantial proportion of which dense zones are at least partially impregnated with binder material; and method of making such a web.  The method generally entails forming a low bond, pattern densified fibrous web; supporting dense zones of the web on a patterned array of spaced supports; displacing the unsupported portions of the web into the spaces intermediate the spaced supports; and applying a binder material to dense supported zones of the web.  For instance, such a web may be made by:  forming a pattern densified embryonic web from an aqueous slurry of low bond fibers; supporting dense zones of the embryonic web on outwardly facing knuckles of an impriiting carrier fabric and subjecting it to a differential pressure to effect displacing unsupported portions thereof out of the top-surface-plane of the knuckles and into the interfila-mentary spaces of the carrier fabric; predrying the embryonic web to a fiber consistency of from about 30 to about 95 percent or more,preferably from about 60 to about 90 percent; gravure impregnating dense supported zones of the predried web with binder material; and finally drying the web.  The degree of impregnating and bonding in the dense zones may be increased by applying mechanical compression to the impregnated zones subsequent to applying the binder material.  The web may also be creped to increase its stretch and bulk, and to increase its softness by disrupting some of the interfilamentary bonds within the web.
