Abstract: Abstract of the Disclosure A rotary retort furnace wherein the retort is supported for rotation at only one end outside of the heated furnace shell such that the retort is cantilevered into the shell.  The rotary retort has a charging door mechanism that cooperates with a skip hoist loading mechanism to provide charges of the parts to be heat treated that are of a uniform size and are introduced into the retort so as to minimize the loss of any controlled atmosphere.  The skip hoist loading mechanism has a vibrating feed hopper that dispenses a weight controlled charge into a skip hoist bucket which, after receiving the predetermined charge of parts, is held in a ready position until such time as a cam mechanism controlling the opening and closing of a door on the charge end of the retort causes the door to open and the skip bucket to be moved to a position wherein the parts are dumped into the retort for heating treating.  The internal auger flight for the retort is made by form-ing a number of toroids from a resilient material, radially cutting each of the toroids and deforming them to form individual flights, and connecting one of the split edges resulting from the cutting to the opposite edge of an adjacent flight such that an axially compressed helical subassembly is obtained.  The helical subassembly is then screwed onto a shaft having a number of guide pins axially on the shaft at predetermined spacings thereby both axially extending and radially compressing the helical subassembly. The shaft and the helical subassembly are inserted into a retort shell and one free end of the subassembly is welded to one end of the retort.  The shaft is then unscrewed from the subassembly while at the same time being forced axially into the retort such that the edges of the helical subassembly fit tightly against the inside of the retort.  After the shaft has been removed,the remaining end of the helical subassembly is welded to the end of the retort./

Abstract: ABSTRACT OF THE DISCLOSURE           A cutter disc assembly for a rotary lawn mower in which the disc has a circular central portion and a peripheral portion with a shallow vertical wall in between penetrated by radial openings.  A plastic pin is mounted cantilever-fashion in each opening.  Each pin has a stiff shank protected by the disc and a stiffly resilient tip portion projecting beyond the periphery of the disc into cutting engagement with the grass.  In the preferred embodiment the shank portion of the pin is protectively received in a groove.  The groove has a rear wall against which the pin bends as the projecting tip of the pin strikes an obstruction as well as a front wall against which the pin bends upon rebound, the walls being curved in outwardly flaring shape thereby to support the shank of the bent pin substantially free of concentrated stress.  Each groove has, in addition, a bridge or "ceiling" which serves as a guide surface to hold the pin in a downwardly-angled working position and to provide frictional damping.  Protection of the tip portion of the pin in its bent state is offered by a ledge or radial extension on the disc either above or below the pin and which "wipes by" the obstruction, shielding the pin from abrading action.  Upwardly swept radial vanes are provided above the periphery of the disc to generate air currents which agitate the grass as it is being cut and to provide a stream of air to move the clippings through the discharge chute.

Abstract: ABSTRACT OF THE DISCLOSURE      Orthodontic brackets and the like are adhesively secured to teeth by means of a self-curing thixotropic acrylic ester monomer composition wherein the monomer has been made thixotropic through the inclusion of fumed silane treated silica and wherein the acrylic ester monomer or monomers have two or more active acrylic ester groups, the thixotropic compositions prior to curing having a viscosity of about 85,000 cps to 4,385,000 cps.      Prior to adhering the orthodontic bracket or other device to the tooth surface, the tooth surface is acid-etched, rinsed and dried.  The thixotropic-activated monomer is then applied to the surface of the tooth or to the surface of the orthodontic bracket just prior to placing the bracket on the tooth. The thixotropic acrylic ester monomer is activated prior to application by blending substantially equal proportions of a thixotropic monomer composition containing acrylic ester monomer, fumed silica, and peroxide catalyst.      The bracket is adhered to the tooth surface through means of the thixotropic monomer mix and left undisturbed while being kept relatively dry until the monomer has hardened.  Arch-wires may then be applied to the orthodontic bracket.

Abstract: SALINITY TOLERANT SURFACTANT OIL RECOVERY PROCESS                  (D#74,495-F) ABSTRACT OF THE DISCLOSURE         Primary anionic surfactants such as organic sulfonates are effective for recovering oil from subter-ranean formations only if the salinity and/or hardness of the formation water is relatively low.  In petroleum formations containing high salinity, or hard water, either the high salinity water must be displaced by a preflush or the primary anionic surfactant must be used in conjunction with an effective solubilizing co-surfactant, such as ethoxylated alcohols or alkyl phenols, or alkyl or alkylaryl thiols, as well as sulfated or sulfonated, ethoxylated alcohols or alkyl phenols.  Optimum performance is achieved if two or more samples of petroleum sulfonate having different equivalent weight ranges and distributions are blended in a ratio which requires the minimum amount of solubilizing cosurfactant to achieve a condition of border-line solubility in the particular formation water in which the surfactants are to be employed.  This ratio may be identified by preparing a number of blended petroleum sulfonate samples in the formation water using different ratios of total primary surfactant concentration to solubi-lizing co-surfactant concentration, and determining whether borderline solubility is achieved, by direct observation or by identifying the sample which produced the minimum electrical conductivity, or at which point the conducti-vity vs. concentration ratio curve exhibits an inflection point.
