Abstract: A discharge device for granular materials, with a housing having at least one inlet for the granular materials, and with a rotor that is connected to a motor, rotates about an axis of rotation and has multiple vanes and chambers located between the vanes, the granular materials being conveyable from the at least one inlet to at least one outlet when the rotor rotates. The axis of rotation of the rotor is vertical and the rotor is preferably arranged inside an essentially cylindrical wear liner.

Abstract: An apparatus for aerosol collection and fluid analysis includes a rotary motor, an aerosol-collection disk configured for mounting on the rotary motor, and a fluid-analysis disk that is also configured for mounting on the rotary motor. The aerosol-collection disk includes at least one interior inlet, at least one peripheral outlet and a passage coupling the interior inlet with the peripheral outlet, and a particle collector opposite the peripheral outlet. The fluid-analysis disk includes at least one fluid in each of a first reservoir and in a second reservoir on or in the fluid-analysis disk and offset from a central axis of the disk, wherein each reservoir has an outlet and a stopper in the outlet of each reservoir to seal the reservoirs; and release of the fluids from the reservoirs is spin-induced.

Abstract: An ice dispensing assembly includes a hopper, a metering disk, a shelf member, and a separating wall. The hopper includes an outlet opening defined in a bottom end of the hopper, and an ice inlet defined in a top end of the hopper. The metering disk is positioned in the hopper and includes a plurality of cavities. The shelf member is arranged to at least partially shield the cavities from a supply of ice held in the hopper. The metering disk is rotatable relative to the hopper between a first position wherein at least one cavity is exposed to the supply of ice to be filled with ice, and a second position wherein the cavity is separated from the supply of ice by the separating wall and ice in the cavity is dispensed through the outlet opening.

Abstract: The present invention relates to a volume-adjustable micro-injection device. The device includes a base structure having a syringe positioning structure and a grip, in which the syringe positioning structure can flexibly accommodate injection syringes with different volumes; a holding structure capable of flexibly adjusting an injection angle of syringe content for easier operation; a qualitative controller capable of accurately controlling injection volume; a pressure pushing structure to hold and push a plunger; an injection controller interlinked with the qualitative controller and the pressure pushing structure; and an eject structure facilitating simple operation and easy replacement of injection syringes.

Abstract: An improved feed dispenser is programmable to allow for a desired feeding schedule. When a feeding interval begins, a dispersion wheel begins operating. A separate spinner plate is used to block feed from the dispersion wheel, and begins operating to allow feed to the dispersion wheel only after a delay of several seconds after the dispersion wheel begins operation. In addition, the dispersion wheel is operated for another period of several seconds after the spinner plate ceases operation in order to clear the mechanism and prevent blockage.

Abstract: An improved spreader assembly adapted to be mounted on a vehicle having a tailgate and a bumper. The improved spreader assembly includes a hopper and a retaining arrangement. The hopper has an upper section and a bottom section. The bottom section has a base surface adapted to at least partially rest on a top surface of the bumper. The retaining arrangement includes a band that fits at least about a portion of a front face of the upper section of the hopper. One end of the band is adapted to connect to the vehicle to maintain at least a portion of a back face of the upper section at least closely adjacent to the tailgate of the vehicle.

Abstract: An apparatus, which is intended for metering bulk materials, has a rotatable cell wheel (9) and a stirrer (2), arranged above the latter, and operates reliably even in the case of very sluggishly flowing bulk materials, in particular with small metering capacities, i.e., with the cell wheel (9) rotating slowly. For this purpose, the invention provides two different, isolated drives for the stirrer (2) and the cell wheel (9).

Abstract: A dispersing system comprises a dispersing apparatus, a storage tank for storing a dispersing medium and a liquid containing a material to be treated, and conduits for connecting the dispersing apparatus in fluid communication with the storage tank. The dispersing apparatus comprises a dispersing chamber, at least one rotationally driven disc, a suction inlet through which the liquid containing the material to be treated and the dispersing medium are drawn from the storage tank into the dispersing chamber by the suction created by rotation of the disc, a discharge outlet, and a medium-separating device for separating the dispersing medium from the liquid containing the dispersed material and selectively discharging the liquid containing the dispersed material but not the dispersing medium from the discharge outlet.

Abstract: A dual hopper coffee cream or product dispenser assembly which has two chambers in which spiral augers are mounted so as to selectively dispense one of two products. Agitators of generally gear-shape configuration are mounted in the hoppers and are driven by the spiral so as to agitate the product for positive and smooth delivery.

Abstract: A laboratory device having a bifurcatable actuator plate assembly superposed and in coaction with a support plate means for securing a plurality of pump-actuated pipettes therebetween and responsive to the actuation thereof to accurately dispense liquids therefrom during a single cycle of the actuator and means for readily establishing a preselected quantity for the replicate liquid injections. The device is supported by height adjustable legs having rubber feet mounted thereto to insure stability.

Abstract: In a spreader of the type used for spreading particulate material onto a roadway and comprising an upper hopper having a lower material discharge chamber terminating in a lower discharge opening, a rotatable spreader element below the discharge opening and a valve mechanism between the discharge chamber and the spreader element for controlling flow of material from the chamber to the spreader, there is provided an arrangement for shifting the valve mechanism between an opened and closed position in response to the direction of rotation of the spreader element. When the spreader element is rotating in one direction, the valve mechanism is automatically opened. When the spreader is rotated in the opposite direction the valve mechanism is automatically closed. This valve operating feature is accomplished by transmitting force through the particulate material within the discharge chamber of the spreader device so that no physical connection is provided between the motor and the valve shifting arrangement.
