  • Patent number: 4291680
    Abstract: This invention provides an improved solar collector of the type employing two concentrically disposed glass tubes having their axial end portions sealingly united to form a double-walled structure, with the annular space between the inner and outer glass tubes being highly evacuated. A heat transfer fluid flows thru the inner tube. The outer surface of the innermost tube is provided with a coating of a solar energy absorbent material to trap energy incident upon the outer tube within the inner tube and the heat transfer fluid. At least one axial section of the inner glass tube is radially inwardly deformed to define a unique bellows configuration to permit absorption of differential thermal expansion of the inner and outer tubes. Improved means for connecting such double-walled tubes in end to end relationship to define a conduit for the heat transfer fluid are also disclosed.

  • Patent number: 4290986
    Abstract: A control system for a plastic extruder which automatically controls both the melt pressure and the melt temperature of the plastic material at the outlet of the extruder barrel. The extruder barrel is divided into a plurality of heating zones and a zone temperature control means individually controls the temperature of each zone in accordance with predetermined zone temperature set points. A melt temperature control means automatically adjusts certain zone temperature set points such that the actual melt temperature is maintained at its desired value. The speed of a rotatable extruder screw is controlled by a melt pressure control means such that the actual melt pressure is maintained at its desired value. In accordance with the present invention, a separate feedforward controller and separate feedback controller are provided in the melt temperature control loop and in each zone temperature control loop such that independent specification of set point and disturbance responses can be achieved.

  • Patent number: 4290533
    Abstract: Halftone printing of a plurality of different colors is employed to produce a composite graphic display on the surface of the glass. Precise alignment is utilized in order to register the halftone printing screens for each color that is deposited on the glass surface. The opaque enamels employed in the decorative process are carefully balanced with respect to each other to obtain the desired color hues. The deposition angles for the alignment of the halftone dots is controlled to minimize the undesirable moire effect.

  • Patent number: 4281758
    Abstract: The invention provides an apparatus for effecting the orientation of shallow disc-shaped articles such as closures, lids and caps so that all such articles are moving at high speed in side by side relationship with each article having its recessed side in the same orientation as all other articles. Such orientation is accomplished by the employment of a single rotating wheel, the elastomeric peripheral surface of which projects through one wall of a feed chute through which the successive articles are moving at high speed in side by side relationship, and co-operates with an aperture in the opposite side wall of the chute to effect the selective direction of the successive articles into either one of two transfer chutes disposed in Y-shaped, tangential relationship to the end of the first mentioned chute according to whether the recessed face of the article is facing toward or away from the wheel periphery.

  • Patent number: 4281774
    Abstract: The invention provides an improved plastic snap cap with a tamper proof band for sealing wide mouthed plastic containers that have an outwardly protruding, continuous, circumferential bead near the top of the container rim. The cap panel has a depending sealing plug for forming a seal on the inside surface of the container. The inside of the closure skirt has a dual function groove formed to provide a frangible circumferential line and to receive the protruding bead when the cap is snapped into position on the container. The portion of the skirt below the groove serves as a tamper proof tear strip, and normally prevents removal of the closure. The groove on the inside of the closure skirt does not extend around the entire inner circumference of the skirt, but leaves a small section of the skirt with no groove or recess to receive the protruding bead. Therefore, when the cap is in place on the container, the protruding bead causes this section of the skirt to bulge slightly outward.

  • Patent number: 4280631
    Abstract: The invention relates to an improvement in a child resistant liquid seal closure and container combination. The container neck has one or more locking projections which engage one or more locking lugs on the interior surface of the closure to prevent rotational removal of the closure from the container. To remove the closure, the cap skirt must be squeezed and distorted to disengage the lugs radially outwardly from the locking projections on the container neck. A snap cap liner is retained within the closure, adjacent the inside surface of the top panel. As the closure is rotated onto the container, this liner snaps into place onto the top of the container neck, and forms a primary liquid seal. Although the final orientation of the outer closure and bottle is effected by the relative position of the locking lugs and projecting cam, this orientation does not affect the primary seal formed by the internal snap cap liner.

  • Patent number: 4279585
    Abstract: A mandrel for forming a container made of foam plastic sheet material. The mandrel defines the internal configuration of the container and also is used to form a rim on the top edge of the container. The container rim is formed by first expanding the rim in diameter by means of cam actuated segments which extend radially outward from within the confinement of the mandrel structure. Subsequent to the diametrical expansion of the rim, the container, including the exterior of the mandrel, undergoes a translation along the mandrel longitudinal axis, thus causing the container rim to fold back upon itself, thus forming a lid receiving bead.
