  • Patent number: 9273663
    Abstract: Subsea power sources and related systems include a housing having at least one first magnetic member, an internal member having at least one second magnetic member, and at least one elastic member positioned in the housing. Movement of the one or more second magnetic members relative to the one or more first magnetic members, which can be obtained by positioning the power source in a subsea environment such that forces therein contact and move the housing or internal member, produces an electromagnetic output for powering a subsea object. Contact between the internal member and one or more elastic members causes the one or more elastic members to impart a force to the internal member to facilitate continued movement and power generation. Power generated in this manner or through other means is usable to operate a subsea kill plant, usable to kill a well or operate a subsea blowout preventer.

    Abstract: The invention is an apparatus to more efficiency move aggregate material from a bulk shipping or storage container to a hot melt or intermediate tank. The apparatus allows the chips to flow from the shipping container into an enclosed chamber by means of a feed chute which opens close to the floor of the chamber so that, as the chips fall out of the feed chute onto the chamber floor, the chips form a pile of a predictable size. By raising or lowering the bottom end of the chute, the size of the pile is varied such that the outer edge of the chip pile reaches the chamber's exit portal, so the chips fall into the hot melt tank or a transportation system, taking the material to the hot melt tank with minimal bridging or complex instrumentation.

  • Patent number: 5460209
    Abstract: An apparatus for dispensing dry ingredient has a plurality of containers, each for a different ingredient. Each has a body having an internal chamber, and a port for dispensing the ingredient, which is arranged gravitationally below the chamber when in use. Each container has at least two baffles adjacent the port. The baffles are inclined and define a passageway through which the ingredient may pass. The passageway is sized and the baffles are inclined such that the ingredient rests upon the baffles. The apparatus also includes a collection stage that is arranged relative to each of the plurality of container ports so that ingredient dispensed from each port is deposited upon the collection stage. The apparatus also includes a vibrator for exciting at least one of the baffles of each container such that the ingredient is urged to pass through the respective passageway and out of the chamber.The apparatus typically further includes a controller for activating and deactivating the vibrators.

  • Patent number: 5413254
    Abstract: A feeder housing is suspended from a material supply bin and has lower and upper cylindrical members with the upper member isolated from the lower member by a flexible collar which also seals the cavity formed by the members. The lower member is suspended from the upper member and has a concave bottom wall with a discharge port. A first fixed baffle next adjacent the bottom wall is a ring with shape of a segment of a toroid with angularly oriented sides having a central opening. A second conical baffle is over the central opening and is axially displaced toward the first baffle between a closed state and a material flow open state wherein material flow is normally arrested until the housing and baffles are vibrated. In a second embodiment, a single fixed baffle comprises a pair of symmetrical cones secured inverted relative to each other over a feeder housing discharge and inlet port.

  • Patent number: 5337762
    Abstract: An apparatus for temporarily storing and distributing comminuted tobacco to a plurality of consuming machines (particularly for distributing cut tobacco to cigarette rod making machines) has a circular tray which receives batches of comminuted tobacco at regular or irregular intervals and is caused to perform movements resulting in conversion of stored tobacco particles into a fluidized bed. Upwardly extending suction pipes draw tobacco particles from the fluidized bed for delivery to the respective consuming machines. The mechanism for moving the tray comprises at least three identical eccentrics which are rotatable in vertical planes and are installed at the underside of the marginal portion of the bottom wall of the tray substantially in line with the inlets of the suction pipes. The eccentrics have identical throws and are mounted in spherical bearings which are secured to the bottom wall by hinges for pivotal movement about horizontal axes extending tangentially of the tray.

  • Patent number: 5333572
    Abstract: A rotary animal feeder that slowly, periodically discharges feed in response to temperature changes. Preferably the feeder is hung from a tree over an animal trail. A cylindrical pail stores a quantity of feed to be dispensed. Feed is drawn downwardly by gravity to an activator assembly comprising a discharge tube in fluid flow communication with the pail interior. A plurality of radially spaced apart discharge orifices are formed in the tube. A convex floor adjustably, coaxially secured within the tube mounts a rotary impeller proximate the discharge orifices. A bimetallic spring beneath the floor torsionally drives the impeller in response to temperature changes. Feed contacting the convex floor is slowly deflected outwardly towards the discharge orifices both by the shape of the convex floor plate and impeller contact. As the temperature changes the impeller slowly rotates, and feed is gently urged toward and through these orifices.

  • Patent number: 5301844
    Abstract: A volumetric dry solids materials feeder comprises a supply hopper, a feed trough disposed below the hopper, and an auger disposed in the feed trough to feed out the material. The trough is anchored to a vibration base, on which is mounted a vibratory mechanism. A vibration transfer spring connects the vibration base to a bracket secured to the hopper. Upon activation, the vibratory mechanism vibrates the vibration base and thus the trough at a predetermined frequency, while the spring transfers the vibration to the hopper. The spring lessens the amplitude of the transferred vibration and changes the frequency thereof, so as to minimize interference (primarily harmonic problems) between the vibration of the hopper and trough.

  • Patent number: 4809880
    Abstract: A parts dispenser apparatus for fungible parts such as seeds, powder, manufactured parts and the like. A feed hopper is positioned to feed parts to the area of a downwardly inclined trough which is pivoted at a fixed end and driven at the discharge end with a horizontal reciprocating motion. The combined effect of gravity and horizontal reciprocating motion causes the parts to align in the bottom of the trough and discharge one-by-one at the discharge end of the trough. An adjustable eccentric permits control of the reciprocation.

  • Patent number: 4790455
    Abstract: A hot melt dispensing apparatus for converting solid thermoplastic material to molten thermoplastic material and for dispensing the molten thermoplastic material comprises a solid thermoplastic material receiving hopper, a vibrated feed chute mounted beneath a bottom opening in said hopper, which vibrated feed chute has a discharge opening laterally offset from the vertical plane of the hopper, and a heated reservoir mounted beneath the discharge end of the feed chute. The reservoir is laterally offset from the hopper so that heat rising from the reservoir does not melt solid thermoplastic material contained within the hopper or within the feed chute. The hopper is rectangular in configuration and comprises three vertical walls and one sloping wall angled relative to a bottom discharge opening of the hopper.

  • Patent number: 4721231
    Abstract: A vessel is provided for holding and discharging loose bulk material, such as cellulosic chips. The vessel includes a cylinder main body with a conical discharge extending downwardly from the body. Chips are fed into the top and discharge from the bottom, with a vibrating discharge structure disposed interiorally of the bottom. In order to prevent hang-up of the chips which might block the outlet a number of prismatic elements are provided attached to the interior side walls of the vessel which terminate generally at the bottom of the main vessel body. The prismatic elements provide void volumes in the loose bulk material flowing downwardly from the inlet to the outlet, so that as the material is being funnelled down for discharge it can fill the void volumes and will not hang-up and block the bulk material outlet.
