Abstract: The disclosure relates to a three cell divider for a rectangular corrugated box which may be fabricated from a single sheet of corrugated board by cutting and scoring operations thereon, and then erected for insertion in the box. The divider comprises a horizontal bottom portion having two panel portions integrally secured to opposite sides and opposite ends of the bottom portion and respectively foldable into an upright, horizontally U-shaped configuration, thus defining two divider walls and four walls abutting the box walls. Projecting tabs on the free ends of two of the abutting walls engage notches in opposed corners of the horizontal bottom portion to maintain the divider in its erected position.

Abstract: Apparatus for taking newly formed glass containers from a blow mold and transferring the containers to a dead plate wherein the take-out tongs for engaging the containers are mounted on a pair of holders that are pivoted like scissors relative to each other. A piston motor is pneumatically driven in one direction to cause the tongs and holders to close, and a spring, urging the piston in the opposite direction effects the opening of the tongs. When the tongs are open, the connection between the piston rod and the holders is a toggle linkage when the links are in a straight line preventing "winking" movement of the tongs toward closing by the fact of the toggle arrangement. Thus machine air closes the tongs and a fairly light spring force opens them.

Abstract: Disclosed is a method of evolving B.sub.2 O.sub.3 from certain B.sub.2 O.sub.3 containing glass-ceramics by heating the glass-ceramic in the pressure of helium as a carrier or transport gas.

Abstract: A snap on child resistant closure has a radial port which may be aligned with a radial port on a cooperating container neck to allow dispensing of granular or pulverulent contents. The closure has a flexible annular skirt provided with a plurality of inwardly projecting lugs. Cooperating outwardly projecting lugs on the container neck normally prevent rotation of the closure to the angular position of alignment of the radial ports. The flexible annular skirt must be squeezed and distorted to disengage the lugs, thereby permitting alignment of the ports.

Abstract: A control system for a glassware forming machine determines the machine speed in accordance with the physical characteristics of the molten glass and the type of glassware being formed. The control system is loaded with timing data representing predetermined forming steps and a machine cycle speed and a control program for generating control signals to the machine forming mechanisms for forming the selected type of glassware. As the machine is operated, one or more physical characteristics of the molten glass entering the machine are sensed and utilized by the control system to adjust the machine speed to an optimum value. The control system also can utilize signals representing the operation of the forming mechanisms to adjust the timing within the machine cycle.

Abstract: The making of a tubular sleeve of thermoplastic material wherein a strip of sheet stock is fed to a rotatable turret having a plurality of rotatable mandrels thereon, the strip is severed into individual rectangular blanks, each having a leading edge and a trailing edge, each blank is formed into a cylindrical shaped sleeve wrapped around a mandrel with the trailing edge overlapping the exterior of the leading edge of the blank, the mandrels are moved past a sealing station and a plurality of bars are rotated so they move successively in an arcuate path generally tangentially to the path of the blank to bring the sealing surface of each bar into engagement with the overlapped edges and apply radial pressure thereto to fuse the edges together and form a seam.

Abstract: A fluorine-free glass composition is disclosed especially adapted for forming the faceplate of a cathode ray tube such as a television tube. The glass is silica based and includes a fluorine-free flux and an X-ray absorber which may comprise lead oxide, barium oxide, strontium oxide, and mixtures thereof. Optionally, the glass may contain still other oxides to impart desired physical properties. The absence of fluorine avoids the usual problems of that ingredient in melting and processing the glass. In addition, the resultant glass as a faceplate provides improved protection to a viewer of a cathode ray tube by excellent absorption of X-rays.

Abstract: A method and apparatus for automatically stopping an automatic glassware forming machine in an orderly sequence of steps. When it is desired to start the machine, a start routine is initiated to move the various glassware forming mechanisms into the appropriate starting positions such that the glassware forming cycle can begin. A stop routine is provided to cycle the glass from the machine and to move the various glassware forming mechanisms into a stationary position where they can be easily accessed. In accordance with the present invention, if the stop routine is intiated before at least one predetermined exit point in the start routine, the stop routine will be entered at an intermediate step such that only those steps concerned with moving the forming mechanisms into the final stationary position will be performed.

Abstract: Disclosed is a method and apparatus for forming multi-directionally oriented plastic articles by accumulating a body of plasticized thermoplastic material in an amount at least sufficient to form the desired article, and advancing the material under pressure from said body forward and through an orifice. The material is non-linearly sheared while being advanced from the body toward the orifice and prior to its issuance from the orifice to induce orientation stresses into the material, and during shearing the material is at a temperature which is conducive to orientation. The orientation stresses are frozen into the material when the material is formed to a desired configuration exteriorly of the orifice by known plastic forming techniques, such as extrusion, blow molding, injection molding, compression molding, thermoforming and the like. During such forming, additional orientation stresses may be induced in the material and superimposed upon those stresses previously introduced thereinto.

Abstract: The invention comprises a combination of a container and a child resistant liquid seal closure with a dispensing spout. The container neck has one or more locking lugs which engage one or more locking lugs on the interior surface of the closure to prevent rotational removal of the closure from the container. A snap cap is retained within the closure, adjacent the inside surface of the top panel, and provides a primary liquid seal. The snap cap is provided with a dispensing spout, which is normally closed by the outer closure. To remove the closure, or to open the dispensing spout, the closure skirt must be squeezed and distorted to disengage the closure lugs radially outwardly from the locking lugs on the container neck.
