  • Patent number: 6375890
    Abstract: In an injection blow-molding process the preform is purposely formed as a smooth walled tube closed at one end and without any thread or other cap attachment configuration about the mouth of the preform. The preform is moved to the bottle mold which completely forms the cap attachment configuration with the bottle in the blow-molding step. A processing dome is also formed from the preform in the blow-molding step to provide means to transfer the bottle to the trimmer which removes the dome. By using the smooth walled preform (without threads or any other cap fastening features), the bottle mold may utilize only a portion of the vertical height of the preform for the bottle. Bottle molds for a variety of bottle volumes and heights may employ the same preform and preform injection mold. The smooth walled preform also permits bottle molds with a variety of mouth diameters to be employed with the same preform injection mold.

  • Patent number: 4867411
    Abstract: A plurality of invert forming mold members are bolted together and have their ends received in internal frames provided at adjacent pipe openings in a manhole. The mold members are formed of relatively thick and heavy polyurethane and are of U-shaped cross-section. A mold supporting plate is provided in each of the internal mounting frames and has an opening configured to matingly receive the endmost mold component.

  • Patent number: 4854542
    Abstract: A concrete column form structured to receive concrete therein for hardening into a building column having a curvilinear exterior surface. The form includes at least two form portions having a flat, thin generally rectangular sheet of resilient material and an elongated, rigid, straight edge bar connected along opposing side margins of each sheet. Each sheet is flexible by manipulation into a curvilinear configuration along its length by opposing rotation and inward movement of each of its connected edge bars. Connected together in side-by-side fashion along adjacent edge bars, the plurality of curvilinear-configured form portions complete the form itself. Both cylindrical and tapered building columns may be easily fabricated either in place or in a factory utilizing this invention.

  • Patent number: 4525133
    Abstract: A packaging system for encapsulating an article within a solid foam material. An article to be encapsulated is supported on a base. A wall enclosure is disposed on the base to form a mold cavity. At the top of the base and above the article to be encapsulated is a cover. Expandable plastic foam in liquid form is introduced into an orifice of the base and the expandable plastic foam advances through a passageway in the base and is discharged from an orifice in the base into the mold cavity to encapsulate the article. The foam material in liquid form solidifies into a solid plastic foam material for packaging the article.

  • Patent number: 4177229
    Abstract: A method for producing precast manhole bases utilizing an apparatus consisting of a mold jacket defining vertical walls and a mold form disposed within the jacket. The form includes a central portion spaced inwardly from the jacket and channel forming members extending over the central portion with inserts attached to the channel forming members and extending into contact with the jacket walls. When concrete is poured over the mold form and allowed to solidify, the bottom wall of the base forms over the central portion with the channel forming members defining the channels in the bottom wall of the base. The channel forming members consist of a first member attachable in a fixed position on the central portion, this first channel forming member being shaped for defining an effluent channel and a central basin in the mold base. One or more additional channel forming members extend radially from the basin, and these include locking means for fixing the members in any desired position relative to the basin.

  • Patent number: 4171791
    Abstract: A releasable mold is disclosed for forming a ribbed transformer casing. The mold includes a plurality of sections first and second ones of which are endwise joined to form an annular ring. Each section has an inner portion with a concave face for forming an annular rib on a transformer casing formed by the mold with each section having an outwardly extending abutment on one opposite side portion and a recess on the other opposite side portion to receive the abutment on an adjacent section stacked thereagainst with the opposite side portions in engagement with one another to thereby accurately position the sections with respect to one another when so stacked and to thus allow a plurality of spaced annular ribs to be formed on the transformer casing. A plurality of fastening ears also extend from each section with each of the fastening ears being apertured to receive a fastening rod therein to releasably fasten the stacked and joined sections in position for forming the ribbed transformer casing.
