An airborne component extraction system includes a source of a positive pressure air stream and a source of a negative pressure air stream. The air streams are directed through conduits to a hood that distributes the positive pressure air stream into a work area, and that draws the negative pressure air stream from the work area to remove airborne components within the work area. Aspects of the hood offer greatly enhanced performance in creating a controlled region for component removal and for drawing and removing the components for the work area.

An external reinforcing strap system for a bulk material cargo container liner comprises a plurality of vertically spaced, horizontally oriented reinforcing straps, or a plurality of horizontally spaced, vertically oriented reinforcing straps and a plurality of vertically spaced, horizontally oriented reinforcing straps, to have their tension levels individually adjusted in an independent manner in order to provide selected sections of the external reinforcing strapping system with requisites amount of tension. In addition, a substantially U-shaped reinforcing gusset system is also disclosed which provides the necessary reinforcement for the rear wall member of the bulk material cargo container liner but with a simplified structure effectively eliminating the aforenoted strapping system.

A reclosable vacuum storage bag that can be hermetically sealed by flat resealable means that extend across the full width of the bag. The flat resealable means are designed to provide a barrier to prevent ambient air from leaking into the evacuated interior volume of the bag. The storage bag is also provided with a plastic zipper. The flat resealable means can be arranged on the product side of the zipper, on the user side of the zipper, or in between two zippers installed in the storage bag.

A headlamp adjuster includes an output shaft driven by a co-rotatable gear. Threads on the shaft engage splines in a thin wall boss, the splines having limited circumferential engagement with the screw. The thin wall boss deflects outwardly in response to forces that build in the engagement of the shaft and splines, to release driving engagement between the splines and the shaft.

The disclosure relates to a slider and a reclosable zipper, particularly a zipper with first and second profiles for watertight vessels, packages or similar devices. The slider is generally C-shaped with an upper arm, a lower arm, and a support wall in between. The support wall includes a groove which captures a rail formed on the first profile so that the slider can slidably move along the rail, riding the first profile. The lower arm includes separator blades which separate the first and second profiles when the slider is moved in the opening direction so as to urge the second profile between the upper and lower arms. When the slider is moved in the closing direction, the second profile travels between the upper and lower arms and is urged into engagement with the first profile by the upper arm. At the final closing position, the slider is stabilized or parked within a cut-out portion of the second profile.

A bulk material cargo container liner system comprises an inflatable bulk material cargo container liner which has at least one vacuum discharge tube member disposed internally within the bulk material cargo container liner and extending along the longitudinal extent thereof for discharging bulk cargo material outwardly from the bulk material cargo container liner, and at least one inflatable air bag component for conducting the bulk material, disposed within the bulk material cargo container, toward the vacuum discharge tube member.

A bulk container liner assembly for use in conjunction with a bulk material cargo container comprises structure incorporated therein such that restraint forces are impressed upon or transmitted to the back or rear wall member of the bulk material cargo container liner, along linearly seamed loci, so as to effectively prevent the back or rear wall member of the bulk material cargo container liner from experiencing or undergoing any outward bulging thereof under the influence of the hydrostatic head load forces generated internally within the bulk material cargo container liner as a result of the charging of bulk cargo material into the interior portion of the bulk material cargo container liner.

A reclosable plastic bag () having a fin seal () which provides a weakness area () that extends into at least one side of the fin seal (). Perforation axes () for opening the reclosable plastic bag () may be aligned with the weakness area (). A method of making the bag is also disclosed.

A new and improved thermal type bulkhead assembly comprises a pair of new and improved thermal type bulkhead members which are adapted to be adjustably positioned with respect to each other in an overlapped mode in the widthwise direction whereby oppositely disposed side edge portions of the pair of bulkhead members can effectively engage the oppositely disposed interior side walls of the refrigerated cargo container, while upper sections of the bulkhead members can flexibly engage the ceiling portion of the refrigerated cargo container. In this manner, the lateral extent or width dimension x of the thermal type bulkhead assembly, as well as the vertical extent or height dimension y of the thermal type bulkhead assembly, can be adjustably varied whereby the thermal type bulkhead assembly of the present invention is effectively universal in structure so as to be capable of being utilized within different refrigerated cargo containers characterized by different internal width and height dimensions.

A side-gusseted bag having a slider-operated zipper. The zipper parts are joined only at one end, the free ends of the zipper parts being separable to allow the associated side gusset of the bag to be inverted to form a pouring spout. The zipper flanges at the joined ends of the zipper are inserted in a corner formed by one gusset panel and an opposing portion of the bag wall. The other gusset panel is sealed to the other bag wall at the elevation of the zipper flanges.

An ultrasonic welding assembly comprising a horn, an anvil and an anvil cover. The horn comprises a generally T-shaped flattening surface and a rail projecting forward of the flattening surface. The rail is shaped to serve as a dam for flowing thermoplastic zipper material during stomping of slider end stops. The horn further comprises a plurality of vertical energy directors designed to direct ultrasonic energy into the mass of zipper material and deflect flowing zipper material toward the dam. The horn further comprises first and second recesses located on opposite sides of a stem of the T-shaped flattening surface. The anvil cover overlies opposing portions of the anvil and comprises a T-shaped cutout. The T-shaped flattening surface of the horn fits in the T-shaped cutout of the anvil cover. The resulting zipper has slider end stops located at opposing ends. Each end stop comprises flattened zipper material having a plurality of spaced indentations, the indentations being formed by the energy directors during stomping. The zipper can be pre-heated prior to ultrasonic stomping. A flange of the zipper can be cooled by fluid during ultrasonic stomping of the zipper parts.

A horizontal form, fill and seal machine has a hollow forming box into which a continuous film is longitudinally fed from a packaging film supply. The forming box has a top, sides and open inlet and outlet ends. A pair of guide bars extend from the outlet end of the forming box adjacent the forming box sides and extending away from the inlet end. The forming box transforms the flat packaging film into a film envelope that extends about the guide bars and has a product-receiving surface that rests on a conveyor between the guide bars. Sealing bars are provided to join the longitudinal edges of the packaging film together and to form seals across the envelope at package length intervals after each deposit of product onto the product-receiving surface. A zipper attaching mechanism applies zipper to the film upstream of the forming box.

A slider (), a slider insertion apparatus () and a method for inserting the slider () on an interlocked fastener or zipper () of a reclosable bag (). A loading rack () feeds individual sliders () to the slider insertion apparatus () wherein the slider () is inserted on the interlocked profiles () being held by a zipper guide (). After insertion, a keeper () and retaining shoulders () of the slider () secure an interlocking member () of the profile () from unintentional engagement with an interlocking member () of the opposing profile (). A positioner () is used to move the inserted slider () and/or to move the attached reclosable bag () in conjunction with driving rollers () of a vertical form-fill-and-seal machine.
