Abstract: A coupler adaptor is provided for use in operative association with a container and a valve. The container houses relatively high pressurized carbon dioxide gas for use in carbonating a beverage. The valve is actuated in order to release the gas to an interface passage formed in the coupler adaptor. The coupler adaptor also has a pair of grooves formed on opposite sides of the interface passage for receiving O-rings. The coupler adaptor is also in operative association with a pressure regulator. The pressurized gas enters the pressure regulator from the coupler adaptor interface passage. In one embodiment, the coupler adaptor remains operatively joined to the pressure regulator without retaining structure due to the balanced gas pressure which results because of the O-rings positioned adjacent the coupler adaptor interface passage.

Abstract: An adhesive applicator for applying an air-curable adhesive to sheets of paper has a nozzle that normally is located in a storage position with the end of the nozzle inserted into a liquid in a sump. This prevents adhesive material in the end of the nozzle from drying out or caking and thereby clogging the end of the nozzle. When the nozzle is to be used for applying adhesive, the nozzle is lifted out of the sump, the sump is pivoted away from the nozzle, and the nozzle is then moved into an operating position for applying the adhesive.

Abstract: A transport device for rapidly changing ladles for the continuous supply of metal melt to continuous casting plants by means of a reciprocating ladle bogie which is provided with means for receiving a sintle ladle. The bogie is moved between an operative position and an inoperative position, the bogie is positioned above a support from which an emptied casting ladle can be removed. In the operative position, the bogie is positioned above a casting station for supplying metal melt. The ladle bogie is open on the side nearest to the support and is rapidly driven back and forth between the inoperative and operative positions to provide a filled ladle from a crane and thereafter move an empty ladle to the support stand-by position for removal by the crane.

Abstract: Pebble-bed nuclear reactor capable of being shut down by a fluidized mass of bodies containing neutron-absorbing material, the fluidized mass of bodies being received in a storage container disposed above the pebble bed during normal operation of the reactor, the storage container being formed with a closable discharge opening, including a piston rigidly connected to the storage container and disposed below the discharge opening thereof, the piston being guided in a cylinder stationary relative to the reactor and being open at the top thereof, the storage container being displaceable in vertical direction between upper and lower end positions thereof, the piston, in the upper end position of the storage container, closing off the cylinder at the upper edge located at the open top of the cylinder and, in the lower end position of the storage container, the fluidized mass of bodies discharged from the discharge opening of the storage container being formed on top of the piston into a discharge cone having a hei

Abstract: Method of emptying a powder or like material out of a container.The powder (9) is conveyed out of the container (1) from its free upper surface by means of a stream of carrier air in a carrier-air pipe (6; 10; 12) provided with openings for the powder. The emptying is facilitated by means of a stream of secondary air from a secondary-air pipe (7; 11; 13). The container is rotated so that the fixed carrier-air pipe may come into the vicinity of the surface of the powder.

Abstract: An indicator/controller for dispensing medical fluids (e.g., intravenously) is disclosed. The device has vented chambers that are movable vertically with respect to one another, thin-plate orifices, capillary chambers, and membrane valves, in addition to other features. The device need be set only once to the desired flow and it will maintain that flow rate regardless of changes in temperature or the height of fluid in the supply.

Abstract: A method and apparatus for dispensing beverages from large and unwieldy replaceable containers, in which the beverage is delivered to the dispensing site. To avoid the need to raise the container to a height permitting gravity feed, and to simplify or eliminate the cleaning of the dispensing apparatus, a hose or tube is connected at one end to the outlet of the container which is located below the level of the dispensing counter, and provides a dispensing outlet at its other end. Pumping is performed by a pump having a rotary element engaging the exterior of the hose.

Abstract: Apparatus for weighing-out material from a collapsible surge bin. The surge bin is mounted above a collapsible frame such that the points of attachment of the surge bin to the collapsible frame comprise a load cell for weighing the surge bin and the contents thereof. The load cells are connected to control circuitry which actuates a gate in the bottom of the surge bin to thereby dispense asphalt-aggregate material from the surge bin. The control circuitry also operates a door in a batcher above the surge bin to thereby regulate the flow of asphalt-aggregate material being delivered into the surge bin.

Abstract: Automatic dispensing apparatus for dispensing predetermined quantities of different beverages from one dispensing station, the invention comprises a housing having a water supply subsystem located therein for supplying either hot or cold water to the dispensing station for ejection into a cup, the housing further having a plurality of dry powder beverage base containers, each container having a powder metering mechanism for ejecting a predetermined quantity of powder into a delivery chute, the delivery chute directing the powder into the cup for mixing with the hot or cold water. Portions of the powder metering mechanisms remote from the containers and upper portions of the delivery chutes, one delivery chute being provided for each container to avoid cross-contamination, are disposed within a warm air enclosure to prevent moisture contamination of the dry powders.

Abstract: A float dispenser is adapted to be floated in a body of water such as a swimming pool, to dispense in the water a soluble solid material carried by the dispenser. The dispenser includes a flotation element from which an apertured receptacle is supported below the water. The receptacle is divided into separate compartments. A single tablet of water soluble material is located within each compartment so that the tablet segregated from the other tablets to expose its maximum surface areas to the surrounding water. The dispenser may be made of two identical integral half sections of molded plastic material which are locked together to lock the tablets within their individual compartments. After dissolution of the tablets, the dispenser may be discarded and replaced with another.

Abstract: An apparatus for applying liquid samples to surfaces, particularly to the separating layer used in thin-layer chromatography and comparable techniques, consisting of a guided pipette which contains the sample, can be placed on the surface with an adjustable contact pressure and which can be removed therefrom again, the apparatus having an electromagnet, the strength of the magnetic field of which can be adjusted so that it holds the vertically freely movable pipette hovering at the required height in relation to the surface, lifts it away from the surface or allows it to rest on the surface under the influence of the force of gravity.

Abstract: A device for detecting the quantity of remaining developer comprises a non-magnetic container for magnetic developer formed with a lower discharge port, a magnet disposed outside and adjacent the bottom of the container for producing a magnetic attraction between the magnet and the magnetism of the developer within the container, a rotary screw roller or a rotary impeller for delivering the developer from the container through the discharge port thereof, a mechanism for causing relative movement of the magnet and the container away from each other against the magnetic attraction when the developer is below a predetermined quantity, and a switch operable by such relative movement.
