Abstract: A helical coil winding inserted in a flexible bag, such as a plastic bag, and connected to or associated with the dispensing spout or neck opening thereof. The helical coil will extend into the bag and will provide a form, about which the flexible wall of the bag will collapse and form, to provide a dispensing tube or passageway leading to the bag spout, as the contents of the bag are removed as a result of a pumping action, suction action or other condition resulting in differential pressure causing collapse of the bag.

Abstract: A sound barrier and sound-absorption panel preferably of a transparent nature so as not to interfere with vision of and light for the machine or other noise-emitting device, to be shielded or enclosed by one or more of the panels. The panel is formed of transparent sound-reflecting material and sound-absorbing material so arranged relatively that the sound waves are received by the panel and deflected into the sound-absorbing material. The reflecting material and sound-absorbing material are arranged to provide one or more sound-receiving pockets or cavities each of which has an outwardly-diverging sound-reflecting wall surface which faces toward the sound-emitter. The sound-absorbing material is in the form of an outwardly-extending member so located in the pocket or cavity as to absorb sound waves which are received in the pocket or cavity and are deflected into the sound-absorbing member by the sound-reflecting wall surface.

Abstract: A foot for use, for example, on cases for electrical instruments or appliances which is formed to not only support the case but also, when used in a combination of two or more, to provide retainers on which the electrical cord can be wrapped. In addition, the foot is formed with a socket arrangement for receiving and retaining the plug on the cord, regardless of whether the plug is of the two-prong or three-prong type.

Abstract: A machine for automatically laying building blocks and the like into a panel. It includes a supply conveyor for feeding a predetermined number of blocks into the machine in proper sequence to form a course, the blocks standing on end. An in-feed support conveyor receives the blocks while still in upright position. A feeder carriage reciprocates over the in-feed conveyor and carries flow-guns for applying adhesive to the exposed upper ends of the blocks and to the exposed edges of the blocks at different times. The carriage is provided with clamps which, as the carriage advances, successively clamp the blocks for pivotal movement about transverse axes. Beyond the in-feed conveyor, is a course-forming and supporting conveyor which is transversely arranged relative to the in-feed conveyor and, over which the carriage advances, which has pairs of parallel guides for receiving the clamped blocks on the feeder carriage.

Abstract: A hand-shovel assembly consisting of a metal shovel head and a wooden handle, the head having a socket for receiving the end of the handle which is forced into the upper open end of the socket and is retained therein without the use of rivets, screws, or other fasteners. The handle end is retained in the socket by means of a set or cured adhesive which is inserted in a viscous state into the open lower socket end and, while still viscous, is forced around the inserted end of the handle by means of a plug of wood driven into the lower socket end.

Abstract: A corrugated container consisting mainly of a lower tray with upright peripheral flanges, upright liner tubes disposed side-by-side on the tray to form a pair of material-receiving chambers, and a surrounding outer shell or tube enclosing the liner tubes, the tubes being interlocked with the tray for maximum strength. A side-dispensing arrangement is provided which includes outwardly-displaceable tabs in the respective liner side walls, outer tube side wall, and flanges of the tray, whereby it is possible, when desired, to form a dispensing passage leading laterally from the lower ends of the material chambers.

Abstract: An end structure for a container body which is of tubular form and of multisided polygonal transverse cross section. It comprises a flat substantially disc-like end with attaching flanges hinged thereto and extending inwardly from the plane thereof, being in number equal to the sides of the body and substantially equal in lateral extent. The attaching flanges are hinged to the disc-like end by an arrangement which permits the end structure to be fitted into position within or exteriorly of the tubular container body and to be fastened in position by means of the attaching flanges.

Abstract: A visible file-card system including a holder and a plurality of cards with cooperating means for pivotally mounting the cards in the holder in superimposed, overlapping, stepped relationship with a portion of the face of each card adjacent its lower edge, visibly exposed. The specific structure for mounting each card on the holder comprises a resilient pivot strip secured to a tab at the upper edge of each card having pivot extensions or pivot lugs on its ends. The holder comprises a back with a longitudinal channel or elongated recess which has flanges at its edges provided with pairs of horizontally spaced opposed pivot openings for receiving the oppositely-projecting pivot lugs of the pivot strips, as the strips are contracted by bending and then allowed to expand to project the pivot lugs into a pair of the opposed pivot openings.
