Abstract: A lined, flip top style, paperboard carton with an integral hinged cover, that includes a positive side lock arrangement between the carton body and cover on each side of the carton, wherein each of the minor upper inner closure flaps has a first section secured to the inner surface of the major upper outer closure flaps and a second section depending from the first section and having extending there through an opening adapted to receive and retain a tab, projecting outwardly from the upper edge of a carton liner secured to certain of the carton side walls, to maintain the cover in a closed position upon reclosure of the carton cover after initial opening.

Abstract: An anti-icing fluid suitable for ground treatment of aircraft, being a glycol-based, aqueous solution containing a hydrophobe-bearing, macromonomer-containing polymer thickener in an amount of less than about 5 weight %. Thickening occurs predominantly by association among hydrophobe groups. Thickening may be enhanced by addition of a surfactant or other materials which act as co-thickeners. Use of this thickened fluid does not adversely affect airfoil lift characteristics during takeoff, because the fluid exhibits shear thinning and readily flows off the aircraft surfaces when exposed to wind shear during the aircraft's takeoff run.

Abstract: A combination, convertible hat/bag/halter top formed from an elasticized strip which can be connected at a first end to form a closed loop, to which a dividable body is attached. The elasticized strip may be connected at one end to form a closed loop. The article converts easily into a hat, a bag and a halter top.

Abstract: The subject is a slide gate or a slide door. There is a DC electric motor which is battery powered. The source of electricity can be from an AC power source such as 110 or 120 volts. A transformer and a converter change the voltage to about 24 volts and rectify the current from alternating current to direct current. There is the electric motor and gear box combination connecting with a drive pulley. Further, there is a pulley on a spaced-apart post. A cable runs around the two pulleys. The drive pulley is connected to the slide gate or the slide door for moving the gate or door.

Abstract: In a mechanical cell for blending elastomer particles and solution into uniform mixtures, a solid core with an entrance surface, an exit surface spaced apart from and substantially parallel to the entrance surface, and a plurality of minute core passageways therebetween for flow of an elastomer-containing hydrocarbon solution from the entrance surface to the exit surface, the passageways have a characteristic dimension of predetermined size to reduce globules of elastomer to small particles distributed evenly in liquid hydrocarbon solution without plugging the passageways. Typically the passageways have a characteristic dimension of predetermined size to reduce globules of elastomer selected from the group consisting of natural rubber, styrene-butadiene rubber, polybutadiene rubber, polyisoprene, a nitrile rubber, and a copolymer of a 1,4-conjugated diene and a vinyl aromatic monomer, to small particles distributed evenly in liquid hydrocarbon solution comprising a vinyl aromatic monomer.

Abstract: A tube for use in a fixed angle centrifuge rotor having a rotor cavity inclined at a predetermined angle .THETA. with respect to the axis of rotation is characterized by one or more marking(s) thereon that indicates the level to which the tube may be filled with liquid without risk of spillage due to meniscus re-orientation. The markings may be graduated in terms of angles at which the rotor cavity may be inclined or in terms of the identity of each rotor into which the tube may be inserted.

Abstract: An interface method for inputting operator-selectable values for speed, temperature and time control parameter are disclosed.

Abstract: A first reactor is used to graft polystyrene to a rubber-like polymer. A second reactor is used to obtain a mixture of styrene and polystyrene. The effluent from both the first and the second reactors are fed into a quiescent reaction zone where phase inversion occurs. The phase inverted material is fed into post inversion reactors to substantially complete the polymerization of the styrene monomer, and any unreacted styrene monomer is driven off to form the improved high-impact polystyrene.

Abstract: The invention relates to grinding tools, particularly to grinding wheels having an annular band of abrasive material at their periphery and provides an improved method of manufacture. A mixture of abrasive material, temporary binder and ceramic bond is heated to paste-like consistency and then coated on to the desired part of a support member, e.g. on to hub (5) of wheel (4) in the form of an annular band (11). The coated support member is then fired to drive off the temporary binder whereby the coating is firmly bonded to the support member.

Abstract: Methods and apparatus for feeding raw polymeric material in pellet form from a hopper into the input opening of an injection molding machine. The apparatus includes a carriage for supporting the hopper upright and a track assembly to which the carriage is slidably connected for allowing repositioning of the hopper. The track assembly includes a feed port arranged so that when the carriage is positioned aligned with the feed port, the raw material flows due to gravity from the hopper, through the feed port and into the machine. A preferred embodiment includes a dual-hopper transport having two carriages slidably mounted on a single track assembly. Cleanout ports are provided in the track assembly for discharging unused raw materials from the hopper.

Abstract: In a process for the mass polymerization of vinyl aromatic monomer wherein vinyl aromatic monomer is polymerized in successive stages of increasing temperature, the improvement which narrows the molecular weight distribution of the resulting polymer comprising incorporating a polymerization inhibiting agent into a polymerizing mass at a point where about 60 to about 95% of monomer is converted to polymer.

Abstract: A container suitable for fruit and vegetable produce has a lid with a multipoint friction lock for retaining the lid closed on the container body provided by a stacking tab projecting from the perimeter of the body opening having undercut side edges and an aperture facing toward such opening while the lid has a notch located for the stacking tab to engage therein when the lid is closed, the ends of such notch being spaced to engage beneath the undercut side edges of the stacking tab and the notch providing a locking portion intermediate such notch ends to engage in the stacking tab aperture in the closed position of the lid. Preferably, the material of the lid is diagonally scored to facilitate bending the lid for interengagement of the stacking tab and notch, and to accommodate moderate overfilling of the container.

Abstract: A laminate is formed, without an adhesive, between an acrylic polymer film and a styrene polymer containing minor amounts of an .alpha.,.beta.-unsaturated carboxylic acid.

Abstract: In a process for the mass polymerization of vinyl aromatic monomer wherein vinyl aromatic monomer is polymerized in successive stages of increasing temperature, the improvement which narrows the molecular weight distribution of the resulting polymer comprising incorporating a crosslinking agent into a polymerizing mass at a point where about 60 to about 95% of monomer is converted to polymer.
