  • Patent number: 3942837
    Abstract: A divider for use in a container, such as a corrugated cardboard box, has a network of intersecting partitions and reinforced folded structures at the ends of the partitions. The reinforcing structures are folded to the main body of the partitions, forming areas of increased thickness which increase the compressive strength of the divider and a container having the divider included therein. The partitions are slotted and interlocked together by use of the slots. The slots have relieved areas at the entrance to the slots and an interlocking protrusion. The opposite edges of the partitions from the slots have relieved areas. The relieved areas at the slot entrances facilitate entry of the strips into the slots and interlocking of the strips together.

  • Patent number: 3942709
    Abstract: A divider used in containers formed of cardboard or like material has intersecting partitions and a tying strip attached to the ends of the partitions and adapted to lie adjacent to the wall of a container. The tying strip holds the partitions substantially parallel so that the divider may be inserted by machine into a container and will remain in a fixed spacial relationship while the container is filled with goods by automatic casing machinery. The partitions and the tying strip have transverse cuts and are joined by interlocking the cuts into a rectilinear network. The corners of the partitions and the openings to the cuts are relieved to allow ease of assembly of the partitions and strip and of insertion of the completed divider into a container by automatic machinery. The portions of the partitions which are joined to the tying strip are folded over and glued to provide additional strengthening elements which increase the strength of the divider and boxes using the divider.

  • Patent number: 3942542
    Abstract: A coin-receiving drum can be used to carry coins, and also can coact with a support to orient those coins so those coins can be introduced into a coin-dispensing unit. That coin-receiving drum has a number of spaced-apart, coin-receiving recesses therein; and those spaced-apart, coin-receiving recesses open to the exterior of that coin-receiving drum. However, a closure member, which is pivoted to the coin-receiving drum, acts at any given time to close the majority of those spaced-apart, coin-receiving recesses. The support has a driving member and a stop; and that driving member will rotate the coin-receiving drum and the closure member until that closure member engages and is held by that stop; and then that driving member will continue to rotate that coin-receiving drum.

  • Patent number: 3937926
    Abstract: A piece of scrip is engraved or printed with groups of patterns which can be sensed by a validator for scrip and one of those groups of patterns will define a code which will permit that piece of scrip to be accepted only by a scrip validator or by scrip validators which have that same code stored therein. Two additional groups of patterns define codes which can cause that scrip validator or those scrip validators to automatically respond to the codes stored therein to actuate price-determining relays within a vending machine. Each pattern is formed by a number of spaced parallel lines, and the various patterns on a piece of scrip can be given different identities merely by changing the spacing between the trailing edges of those spaced parallel lines. The patterns in each group of patterns will be sensed in a prescribed sequence, and the sequentially sensed patterns in any of those groups of patterns can be given various identities.

  • Patent number: 3938067
    Abstract: A current-limiting, single-element, dual-function, electric fuse has a fusible element with at least one "weak spot" of very small cross section; and the temperature of that weak spot will exceed eighty percent of the melting temperature of the material of that fusible element when that electric fuse operates at its maximum continuous current carrying capacity. An appreciable amount of the heat, which the weak spot generates in response to a low but potentially-harmful overload, will be conducted to the inner surface of the housing for the electric fuse by the arc-quenching filler; and a substantial percent of that conducted heat will pass to, and be radiated by, the exposed outer surface of that housing.

  • Patent number: 3935873
    Abstract: A coin-moving member adjacent a coin-holding tube has a surface which can engage one part of the periphery of the end-most coin. Each endmost coin defines a plane perpendicular to the axis of the coinholding tube; and a connection between a coin-moving member and a source of motive power is intermediate that plane and the opposite end of the coin-holding tube. As the source of motive power moves the coin-moving member to dispense a coin, an axially-directed component of force will develop between the coin-engaging surface of the coin-moving member and the periphery of that coin; and that axially-directed component of force will be directed toward the opposite end of the coin-holding tube, and it will hold that coin-engaging surface in tight engagement with the periphery of that coin.

  • Patent number: 3934894
    Abstract: An enclosed cart for storing and transporting refuse or other bulky materials has an enclosing lid which overlies the opening to the container, preventing the undesirable entrance of rain or extraneous debris. The cart has a small central hole in the floor panel which allows water to drain from the interior. The cart has wheels at one edge and a handle at the other whereby it may be lifted and moved easily from place to place. The interior of the cart is adapted to enclose cans or bags. Special bag holders fit into the interior of the cart and cooperate with the upper edge of the cart to hold bags. The bag holders may be single or plural whereby one or more bags may be held. The bag holders hold the tops of the bags open and prevent the tops of the bags from being drawn into the interior of the cart under the weight of added material. The bag holders are formed of sheet metal stampings or fabricated from bent wire.

  • Patent number: 3934821
    Abstract: A bulk tank cooling and storage apparatus has heat exchange surfaces substantially covering the side and end walls of the tank. The tank is supplied with a horizontal rotating disc liquid distributor which uniformly distributes the liquid in a sheet over the heat exchange surfaces so that it flows downwardly over the surfaces in a thin film and is cooled by heat exchange operating in cooperation with the heat exchange surfaces. Even distribution of the liquid is provided by the rotating disc distributor which expels liquid from the periphery of the rotating disc and propels the liquid against the walls of the tank. Liquid fed into the tank is directed to the center of the rotating disc where a cylindrical dam or well holds a reservoir of the liquid and distributes it on the surface of the disc. The periphery of the disc may have a knife edge which helps the film of liquid to flow off smoothly without atomization.

  • Patent number: 3932736
    Abstract: A system for automatically producing pellets, and more particularly feed pellets from a milled material. A mixture of milled material of a selected composition is fed to a pellet producing means. The moisture content of the material as it enters the pellet producing means is automatically controlled within prescribed limits as is the feed rate of the material into the producing means, such that there can be no increase in the feed rate unless prescribed moisture conditions are satisfied. Further control means control the feed rate of the material in accordance with prescribed load conditions on the producing means and establish an automatic sequencing of various controlled parameters when an overload condition occurs to prevent damage to the system, relieve the overload condition, and restart the system.Once the system is activated, operation is completely automatic to establish optimum conditions for maximum productivity, pellet quality, and system life.
