  • Patent number: 4192438
    Abstract: A gun type device for removing radioactive gas from a sealed hypodermic type vial. The device includes a sealable recess including a pair of concentric hollow needles which penetrate the vial upon the closing of the chamber with a vial still remaining within a lead shielded container which then forms a part of the sealed chamber. An inlet port under control of a push button valve conducts an inert gas under compression through one of said needles to displace and mix with the radioactive gas and force the same through the other of said needles to an outlet port controlled by a second valve.

  • Patent number: 4181246
    Abstract: A closure for a collapsible tube having a base portion mounted on the reinforced dispensing end of the tube. The base portion of the closure defines a bore communicating at one of its ends with the interior of the tube. The opposite end of the bore opens on the surface of a substantially spherical portion of the base member and serves as an outlet through which the tube contents are dispensed. This outlet is selectively opened and closed by a cap member fabricated from a semi-rigid material which defines a cavity which rotatably receives the spherical member therein. The tube contents are dispensed by rotating a port defined in the cap member into alignment with the base portion outlet and collapsing a portion of the tube wall. In one embodiment means are provided to assist in guiding the rotation of the cap member with respect to the spherical member for purposes of aligning the base portion opening and the cap member opening.

  • Patent number: 4177941
    Abstract: There is disclosed a metering device for metering finely divided material which is capable of handling both free-flowing powders and non-free-flowing powders. The device comprises an upright mixing chamber or reservoir having an axially-disposed stirrer therein. Adjacent thereto is a motor-driven shaft having a metering disc attached thereto with a portion extending into the mixing chamber. The motor-driven axial shaft of the metering disc is connected to the axial shaft of the stirrer by a gear train. Each shaft has replaceable gears attached thereto, adapted to mesh with an idler gear. The idler gear is mounted on an adjustable arm so that the position thereof can be changed when one or both of the replaceable gears is replaced by a gear of different size. In one form of the invention, the stirrer comprises radially-disposed arms projecting from the rotatable shaft, each arm of which is angularly displaced with reference to the arm above or below it and is curved away from the direction of rotation.

  • Patent number: 4176767
    Abstract: A bin with a hopper bottom is provided for storing and dispensing dog food, including a sliding gate located at the bottom of the hopper for regulating flow of dog food from the bin. The gate includes a solid center section which prohibits flow of dog food from the bin when positioned across the outlet hole at the bottom of the hopper, an opening which allows dog food to flow from the bin when positioned in alignment with the outlet hole, and handle means on its forward end projecting out the front of the dog food dispenser for convenient manual operation. The sliding gate also includes unique forms of agitators connected thereto and protruding upwardly through the outlet hole and into the bin in such a way as to agitate the dog food in the vicinity of the outlet hole as the gate is slidably moved thereby breaking down bridging of the dog food particles and encouraging smooth flow of the dog food from the bin.

  • Patent number: 4175797
    Abstract: An endless self-laying tread or track such as used on self-propelled mining machines and the like, the tread or track being comprised of a plurality of articulated crawler pads configured so as not only to effect good ground engagement but also to assist in preventing the tread or track from becoming clogged. A plurality of the crawler pads are arranged in interdigitated relationship and connected by elongated pins. As so connected open ended spaces are provided at either side of the tread for engagement by the teeth of a driving sprocket. By this arrangement such teeth may be wider and thicker. The space occupied by such a sprocket tooth, being open ended, greatly facilitates the dispersement of any accumulated packing between the tooth and the crawler pads in a sideways direction. One or more pins or pintles are used to connect each adjacent pair of interdigitated pads.

  • Patent number: 4172540
    Abstract: A dispensing closure having a cap with an opening extending through the top of the cap and having a lid mounted on the cap so that it is capable of being moved between a closed position in which the lid closes off the opening and an open position in which the opening is exposed can be constructed so as to utilize a spring mounting the lid on the cap. One of the ends of the spring employed is secured to the cap so that the spring is incapable of being pivoted relative to the cap while the other of the ends of the spring is pivotally connected to the lid. The spring is connected to the lid at a location such that the spring has to be bent and such that the lid has to be pivoted relative to the spring in order for the lid to be moved between the noted open and closed position. The spring serves to hold the lid relative to the top of the cap so that the lid is held against movement in the open position by the spring.

  • Patent number: 4169545
    Abstract: A plural component dispensing system includes supplies which furnish first and second components under pressure to a dispensing apparatus having first and second valves, respectively. Each of the valves includes a rotatable valve member in a combination retainer and seat. The valves are connected to first and second pinion gears, respectively, and a rack engages each of the pinion gears. The rack is attached to a piston which is disposed for reciprocation in a cylinder in response to fluid pressure on one side or the other of the piston. Actuation of the piston in a first direction provides paths for component flow through the first and second rotatable valve members and through first and second orifices, respectively, into a mixing chamber. The first and second orifices are disposed to provide impinging streams of the first and second components, the impingement insuring complete and thorough mixing of the components.
