Abstract: A safety closure is provided for closing the open neck of containers having a bead type finish formed on such neck end. The closure comprises a unitary element molded from a resilient plastic material and having a generally horizontal circular panel portion and an integral, generally vertical peripheral flange portion. The flange portion is provided with an internally projecting rib which snaps into engagement with the groove normally provided beneath the bead of a container bead finish. In the closed position of the closure on the container, the bottom edge of the closure flange is flush with the side wall of the container neck and cannot be engaged by the fingers to pry the closure off of the container.

Abstract: A container comprising a hollow tray and a domed lid, each of which are of unitary molded plastic construction. The tray has a planar bottom wall peripherally encompassed by a generally outwardly and upwardly flaring upstanding wall with a rim over which the lid is snugly attachable. Peripherally interspaced indents are molded in and offset interiorly from the upstanding wall of the tray and define interiorly facing surface regions disposed in proximately perpendicular relationship with the bottom wall of the tray.The container is particularly suitable for packaging a plurality of small dimensionally corresponding containers, such as ampuls, or the like. As such, it provides a package accommodating a plurality of rows of containers together with an upstanding plastic separator sheet separating each row of containers.

Abstract: A pre-packaged blood collecting and separating device and process of its preparation are disclosed in which the device contains a mixture of liquid polybutadiene and an inorganic, inert filler, such as silica, as a thixotropic gel adapted at rest to form a sealing barrier between separated blood phases. The device and gel are subjected to sterilizing radiation to form a substantially sterile device, substantially free of backflow contamination, without degradation of the physical properties of the gel.

Abstract: Method and apparatus for blow molding plastic articles from preformed parisons by reheating the parisons and then stretching and blowing them. The parisons are conveyed in series to a plurality of fixed heating stations at which the parisons are fixedly positioned for heating, the parisons being rotated for uniform heating. The heating is enhanced by blowing air under pressure through a tunnel enclosing the successive heating stations. Finally, the parison is stretched and blown at a blow station in a blow mold of unique design.

Abstract: The invention is a solar energy conversion apparatus in which several evacuated, glass tubular collectors are connected together in a liquid circulation system for controlled movement of a liquid between the interior of the collectors and a storage tank. Liquid circulation is controlled by sensors and switches therefor in regulating operation of valves and/or a pump. The conditions for circulating the liquid rely upon (1) sensing a need for energy at the storage tank, (2) sensing solar radiation availability, (3) sensing thermal conditions in the solar collector tubes to avoid high temperature and thermal shock, and sensing a need to withdraw hot liquid and add more.

Abstract: A cup-shaped overcap made of deformable plastic material is provided with plural protruding lugs along the inside surface of the cup wall nearly adjacent the open end of the overcap. The lugs snap over the apex of an annular bead on a bottle holding the cap in inverted position over a closure on the filled bottle. The overcap protects the closure and end of the bottle and provides a drinking/measuring cup for use with the bottle and contents. The lugs and bead provide for arcuate distortion of the cap when applied, which permits use of less rigid tolerances in cap and bottle.

Abstract: A parison handling assembly receives tubular plastic parisons from a random bulk storage, orients the parisons, and feeds the parisons in a controlled manner to one or more blow molding machines. Parisons are stored in the random bulk storage and fed at a controlled rate by a metering apparatus to a parison orienter which orients the parisons into a closely grouped arrangement wherein the parisons are both upright and side-by-side. The parisons are fed from the parison orienter to a parison escapement mechanism which holds the parisons temporarily. The escapement mechanism is actuated to release parisons into a parison transporter depending on the production demands of the individual blow-molding machines. Released parisons, from the parison escapement mechanism, move along the parison transporter to be pushed axially into stuffer tubes. The stuffer tubes hold the parisons in properly oriented, end-to-end relationship for delivery to the actual loading station of the blow-molding machine.

Abstract: A high mobility wheeled vehicle for transporting long loads, such as trimmed tree trunks or whole trees, over roadless terrain. The vehicle has front and rear quad wheel assemblies pivotally connected to a centrally disposed elongated bed frame so as to permit lateral rotation of these assemblies about a roll axis disposed below and parallel to the longitudinal axis of the bed frame. A linkage type roll control means interconnects the quad wheel assemblies and the bed frame to proportionately control the relative angular movement of the bed frame with respect to the quad wheel assemblies. The roll control means includes a plurality of interconnected links plus a pair of power extensible links for selectively adjusting the steady state position of the vehicle bed relative to the quad wheel assemblies in either direction.In a modification, parallel links are employed to interconnect the quad wheel assemblies with pivotally mounted load supporting cradles.

Abstract: A process for forming organopolysiloxanes from trialkoxysilanes and the resulting resinous products are disclosed, characterized in that the organopolysiloxane resins have increased hardness when hydrolysis and condensation of the trialkoxysilanes are carried out in aqueous solution acidified by formic acid and at a relatively high strength previously regarded as inoperative. The formic acid, for example, may be present in an amount greater than 700 ppm. After hydrolysis of the trialkoxysilane, the resulting silonetriol is condensed to form the organopolysiloxane.

Abstract: An improved control system for the cutting of spirally wound composite can "sticks" with accurate registration. Cutting knives, which cut a wound tube into sticks, are mounted on a servo-driven sled, which is in turn mounted on a reciprocating carriage. The point of cutting is controlled by adjusting the position of the carriage (for long term errors) and the sled (for short term errors). Factors analyzed to determine where the carriage and sled should be positioned include the phase relationship between the label and the carriage, the angle at which the label is wound onto the tube, the point at which the label is wound onto the tube, label stretch, and misprinting of reference marks on the label. Means may be included for automatically rejecting sticks which are out of registration.

Abstract: An improved safety closure for containers of harmful products includes an inverted cup-shaped body member formed of resilient plastic material and an integrally molded locking flap connected by an integral hinge to the top periphery of the body member. The locking flap folds into a conforming recess in the top surface or panel of the body portion, and, in its folded position, all edges of the locking flap are flush with the adjacent surface of the panel. One or more dispensing openings are provided in the panel and sealing means are provided on the bottom of the flap to close the dispensing openings in the folded position of the locking flap. Two distinct sets of cooperating locking surfaces are provided on the flap and body portion to retain the locking flap in its folded position. The one set requires a vertically downward pressure on a specific area on the panel to release.

Abstract: An end closure for a composite can body wherein the closure has a circumferential weakening line formed therein to facilitate the removal of the central portion of the closure by a can opener wherein the weakening line is formed by an offset shearing operation.

Abstract: This invention relates to a method and apparatus for determining whether a glue drop is present on the reflective inner surface of a closure. Collimated light is projected onto the reflective inner surface of the closure, and a measurement is taken of the amount of light which remains collimated after reflection from the closure. The measurement of the amount of light reflected in this way is used to determine whether a glue drop is present.
