| 321 | Ice dispenser control | US535554 | 1983-09-27 | US4496087A | 1985-01-29 | James R. Marks |
| An ice dispenser control wherein a plurality of solenoids are selectively operated by switches engaged by cups of different sizes placed in a dispensing space of the ice dispenser. The solenoids cause a delivery passage of the ice maker to be closed at a selected level thereof by a divider while concurrently a closure normally closing the delivery end of the delivery passage is removed therefrom so as to permit ice bodies in the passage between the delivery end and the actuated divider to be dispensed to the cup in the dispensing space. The control causes an agitator in the ice storage bin to be operated for a preselected period of time each time ice is delivered from the delivery passage. Additionally, the control is arranged to cause agitation of the ice in the ice storage bin whenever no dispensing of ice is effected for a preselected long period of time, thereby to prevent conglomeration of the ice bodies in the storage bin. The control is arranged to provide the timing operations automatically through a clock and timer devices of the control circuitry. | ||||||
| 322 | Liquid dispensing pump arrangement with selective stroke restriction | US363835 | 1982-03-31 | US4433799A | 1984-02-28 | Douglas F. Corsette |
| A liquid-dispensing pump arrangement permits positive setting into various full-stroke, stroke limited, and off positions by rotation of the dispensing head thereof. The arrangement includes a reciprocating pump having a dip tube, a pump body, and a depressible stem and which is supported in a screw cap or other closure. A pedestal on the screw cap has longitudinal detents on a circumferential surface thereof, and also has a helical ramp thereon extending at least part way around the stem. A finger-depressible push-button dispensing head atop the stem has a radial outlet nozzle and a depending skirt which overlaps the circumferential surface of the pedestal. Fins or vanes on the skirt are spaced apart and engage the detents on the pedestal. The vanes are resiliently flexible and normally engage the cutout detents to establish each rotational position, but can be deflected by manually turning the dispenser head so that the latter can be easily rotated to another desired position. In a locked or off position, an upper surface of the ramp prevents any downward travel of the dispenser head. | ||||||
| 323 | Solar powered liquid metering device | US227183 | 1981-01-22 | US4407637A | 1983-10-04 | John C. Newby |
| A solar powered liquid metering device is disclosed including a solar chamber sealed from atmospheric pressure and partialy filled with a liquid to be metered. Trapped within the device above the liquid is an expansible gas. Also included is an overflow chamber partially filled with the liquid and coupled to the solar chamber to allow fluid communication between the two bodies of liquid. An overflow pipe has an end located within the overflow chamber. When the gas expands due to solar heating liquid is forced from the solar chamber into the overflow chamber and then out the overflow pipe. Various mechanisms are described to keep the liquid level within the overflow chamber no lower than the lip of the overflow pipe. | ||||||
| 324 | Portable liquid metering device | US22984 | 1979-03-22 | US4265370A | 1981-05-05 | David H. Reilly |
| A portable liquid metering device for detachably securing to the opening of a liquid container and adapted to discharge a predetermined volume of liquid upon tipping and having a register for counting and displaying the number of times the bottle is tipped. | ||||||
| 325 | Syringe adaptor assembly | US022698 | 1979-03-22 | US4231494A | 1980-11-04 | David L. Greenwood |
| A connector is provided for attachment of a syringe to a dispenser adapted to provide measured quantities of pressured gas to the syringe to displace the contents of the syringe in measured drops. The connector includes a flexible conduit attached at one end to the dispenser and attached at its opposite end to the filling end of a syringe while gripping the oppositely disposed projections, or "ears", of the syringe. There is an externally threaded tube at the syringe end of the flexible conduit, terminated by a stopper member which has a cylindrical end portion sized to fit loosely within the filling end of the syringe, which end portion is joined to a sealing flange. The sealing flange abuts the flat surface at the filling end of the syringe while the syringe "ears" are retained within oppositely disposed channels after a knurled ring on the externally threaded tubular member is rotated. | ||||||
| 326 | Fluid-dispensing apparatus having level control and alarm means | US601147 | 1975-08-01 | US4014010A | 1977-03-22 | Walter Joseph Jinotti |
| The apparatus comprises a flexible tube through which fluid flows from a supply, and a opaque ball which is adjustably disposed within the tube. When fluid is first fed through the tube, an air bubble forms, and the location of this bubble is set by squeezng the tube and forcing the air bubble to an upper portion of the tube. The opaque ball rests on the top surface of the fluid in the air bubble. A photoelectric detector assembly comprising a source of light and a light detector is mounted on the tube, with the beam of light interrupted by the opaque ball. The light detector is connected to an electronic circuit which is arranged to perform no function so long as the beam of light from the source is interrupted by the ball. When all of the fluid has been fed through the tube from the source, and the level begins to drop in the tube, the opaque ball drops below the light beam and permits the light detector to receive light from the light source, and the resultant current flow operates the electronic circuit to provide a warning that the fluid has dropped below the set level and that the tube itself will be empty in a known period of time thereafter. | ||||||
| 327 | Portable mixing plant for concrete and the like | US596461 | 1975-07-16 | US3994404A | 1976-11-30 | Jean-Francis Kisovec |
| A mixing plant which is portable and adapted to mix material, such as for on-the-site mixing of concrete and the like, and which mounts on a truck to be readily transported from site to site. This mixing plant includes four transportable units mounted on a truck and each comprising a belt conveyor, a weighing system operatively carrying the conveyor and adapted to weigh material on the top run of the latter, a hopper mounted above the belt conveyor and including a coarse dispensing outlet and a fine dispensing outlet with the latter positioned a predetermined distance from the coarse dispensing outlet and downstream of the latter relative to the displacement of the top run of the conveyor, a levelling bar of adjustable height extending lengthwise transversely of the conveyor between the two dispensing outlets, and with trap doors and actuators to adjust the opening and closing of the outlets. | ||||||
| 328 | Portable siphon apparatus | US32919173 | 1973-02-02 | US3897808A | 1975-08-05 | STEWART JR TOBIAS |
| Portable siphon apparatus for transferring a quantity of liquid from a liquid source to a container. A container is provided having a volume sufficient to hold a desired quantity of siphoned liquid. The container volume is in selective communication with a conduit having a remote end for immersion into a liquid to be siphoned. The conduit end in communication with the container is selectively closable from fluid communication with the interior of the container, and a pump is operable to lower the air pressure within the closed conduit to initiate siphon action.

| 329 | Method and apparatus for automatically metering predetermined volumina of a liquid | US3765568D | 1971-10-07 | US3765568A | 1973-10-16 | LEIFERMANN W |
| A method of automatically metering predetermined volumina of a liquid by arranging the liquid within an airtight enclosure and controlling, in a dispensing operation, the outlet valve by the resulting mechanical deformation of a diaphragm that is in communication with the enclosure and deformable by air pressure variations of the air entrapped within the system. The apparatus essentially comprises a sealed reservoir with an outlet valve, a diaphragm in communication with the reservoir and a sensing device for sensing deformations of the diaphragm to control the outlet valve. An optional timer may provide a no-liquid condition signal.
