Abstract: The disclosure relates to a modular form of solar energy collector apparatus in which several double-wall glass tube collectors, each with vacuum jacket, depend from opposite sides of an elongated manifold. The manifold includes split halves of foamed polymer insulation and rigid fiberglass reinforced skin thereon, assembled about closed-looped, serpentine liquid carrying tubes preferably of metal or glass in U-tube configurations depending from the manifold halves and extending into the larger double-walled glass tubes, the serpentine tube being connected, respectively, into inlet and outlet header pipes. The interior chamber of the collector tubes is closed by the manifold, thereby enclosing a part of each U-tube branch of the serpentine in a non-turbulent air space. Solar energy collected on the absorber surface of the inner glass tube wall is transmitted to the U-tube and liquid therein. The U-tube within the collectors is blackened and non-reflecting.

Abstract: A method for measuring the thickness of transparent articles utilizing a plural component light beam. In the most general sense, the present invention involves the generation of a plural component light beam which is generally symmetric about the optic axis of the system. The light distribution which results from this arrangement is used to illuminate a transparent article. The result is separate reflections from the front and rear surfaces of the article for all of the components of the light beam. If these reflections are imaged in a detector plane which is conjugate to a plane in the vicinity of the article, a pair of co-planar images are formed, one image representing reflections of all of the plural components from the rear surface and the other image representing reflection of all of the plural components from the front surface. Measurement of the average separation of the images will give a value that is proportional to the thickness of the article at a point lying along the optic axis of the system.

Abstract: A child-resistant, safety closure for a container having a dispensing end including a threaded neck portion. The closure features an inner sidewall threadably attachable on the container neck portion and an outer sidewall having a flexible and resiliently distensible distal end portion with at least one interlocking member adapted to automatically interlockingly engage the dispensing end of the container when the closure is in either a fully closed or in at least one additional, partially removed position on the container neck portion. Removal of the closure requires manual compression of the outer sidewall at locations straddling the interlocking members, coupled with concurrent retrogressive movement of the closure. Ordinarily, such manual manipulation must be repeated at each interlocking position of the closure. Moreover, as a further safety factor, the interlocking members are inaccessibly and unobservably secluded within the interior confines of the closure when it is interlocked on the container.

Abstract: An improved method and apparatus for two-stage blow molding especially suitable for large plastic containers, wherein an overhead shuttle mechanism transfers a blown preform from a preform station to a final blowing station and then to a separation station where the completed article is separated from the upper tail by which it was suspended from the shuttle mechanism during each of the transfer steps. The lower tail is separated from the preform prior to removal from the preform blowing station.An alternative form uses a rotary indexing transfer mechanism, wherein the shape of an upper flash or tail-forming clamp half which is carried by the indexing mechanism creates an interlock with the flash permitting the article to be suspended from and transferred by such single clamp half throughout the operation.

Abstract: There is disclosed a gaseous discharge display device having a plurality of gaseous discharge sites and at least one active, working dielectric surface exposed to the gas discharge at each discharge site. The active gas contacting dielectric surface is coated with a protective film in an amount sufficient to prevent the formation of undesirable contaminants on the active dielectric surface, particularly during the manufacture of the device. After the complete assembly and gas filling of the device, the protective film is removed from the vicinity of each gas discharge site by the application of a gas discharge voltage at the site sufficient to sputter the protective film away from the discharge site without sputtering the active dielectric surface.

Abstract: A method and apparatus are disclosed for forming a plastic container by a blow molding operation. In the method, a tubular thermoplastic parison is blown to a preform within a first mold by a blow pipe inserted into one axial open end of the parison. Prior to removing the preform from the first mold, a secondary opening is formed in the wall of the preform, either by a spike-shaped piercing surface over which the parison is expanded or by a vent port through which blow air is exhausted to rupture an opening in the preform wall. The preform is then transferred to a second mold, which pinches shut the initial blowing opening of the preform. A second blow pin is inserted into the secondary opening to supply blow air under pressure to expand the preform to a container.

Abstract: A method of sorting articles having major and minor surfaces such that they normally assume a position presenting one major surface against a support surface and an opposed major surface spaced from said support surface wherein the articles are aligned on a support surface and advanced in a guided single file past a discriminating means which alters the path of advance of those articles having a first given orientation of its major surface relative to the guide means. The articles of the opposite major surface orientation relative to the guide means support surface are thus segregated. Both segregated groups of articles can be merged following their orientation to a like major surface relationship to a reference support surface.A turntable imposes centrifugal forces on the articles to be sorted to pass them to a tangential guide chute in single file.

Abstract: The invention disclosed sets forth a machine for forming a sleeve of a shrinkable, cellular polymeric material from a predecorated web. The web is processed to provide (1) a partial-depth slit along the longitudinal dimension, and (2) cross-dimension pleats. Predecorated shrunken neck labels are formed from the web for overlying the neck and closure of the bottle and including a pilfer-proof feature. Such a label is formed from the processed web by cutting a blank having the cross pleats therein and winding the blank on a mandrel to overlap the ends and seam the overlap to make a sleeve. The sleeve is stripped onto the top neck end and over the closure of a bottle of room temperature to a label position and shrunken to a snug fit, the pleats absorbing wrinkles that occur in shrinking the material onto a "cold" bottle.

Abstract: There is disclosed a mold assembly for casting posts and plate connector straps onto stacks of plates of lead acid type batteries wherein molten metal is circulated through one or more channels in the assembly and selectively damned to overflow into adjacent mold cavities. Cycle time and properties of the posts and connector straps are improved by constructions which impart a large thermal mass to the channel walls and a small thermal mass to the mold cavity walls. Thermal isolation of the mold cavity walls from the channel walls further enhances these conditions whereby the molds can be elevated in temperature prior to the casting operation and rapidly cooled during that operation. Cooling of the post mold cavities earlier and at a faster rate than the strap mold cavities increases post strength. A mold frame construction containing the molten metal flow channel and one or more inserts for the frame provide the desirable thermal properties while lending flexibility to the apparatus.

Abstract: There is disclosed a control device for a sleeve label forming and applying machine of the type disclosed in U.S. Pat. No. 4,013,496, for labelling bottles, which controls the number of sleeves being fabricated to correspond with the number of bottles going through the machine. The control includes a pivoted switch arm across the bottle path at the outlet from a timing worm loading bottles into the machine. The arm when engaged by a bottle actuates its switch in the control circuit for engaging and disengaging the power drive means operating the supply of the label stock to the sleeve fabricating mechanism of the machine. The first bottle and every bottle into the machine is assured to receive a sleeve label, and the last bottle receives the last sleeve label fabricated.
