Abstract: A movably mounted supply dispenser for bulk material is provided that has apparatus for mounting a container having inlet and outlet ends on a rack having spaced vertical supports. The mounting apparatus provides translation of a given generally horizontally directed thrust applied against the outlet end of the container into an angular motion of said container having upward components and horizontal components at both the inlet and outlet ends. The upward motion of the inlet end is greater than the upward motion of the outlet end for the given applied horizontal thrust. A system of such containers may also be provided in a freestanding rack allowing for the dispensing of many different bulk products.

Abstract: A dispensing apparatus for aseptic measurement and filling of a fluid product is proposed, which, particularly as a result of the simple embodiment of a control slide valve, is especially suitable for the development of a multiple dispensing apparatus.

Abstract: In an automatic boiler having an internal hopper, a regulator plate 12 controls the flow under gravity of fuel to the firebed. For small particled fuel in particular the plate is provided with a torque 23 which causes a central thinning of the firebed. Thus, a centrally disposed shallow firebed is formed so that primary air can rapidly break through at this point to burn off volatile gases as they are distilled and cause ignition over the whole firebed.

Abstract: A multi-size pill dispenser comprises an enclosing cabinet within which are formed a plurality of horizontally juxtaposed pill containing hoppers. Each hopper terminates downwardly in a square opening through which the pills can drop by gravity. A slide is reciprocal below each hopper and includes a triangularly shaped window, portions of which can be urged into registry beneath the hopper opening. An adjustable stop is provided to limit the forward movement of the slide relative to the hopper opening whereby the area of the slide triangular window which can be pulled into registry below the hopper opening can be precisely controlled to regulate both the size and number of pills that can be dispensed from each hopper upon each reciprocation of a slide. By adjusting the forward limit of travel of each of the slides, various sizes and types of pills or other articles can be dispensed, one at a time, from the plurality of hoppers.

Abstract: A pneumatic discharge arrangement for railway hopper cars includes a housing secured to a discharge end of a hopper including a chamber having an elongated opening.

Movement of the sliding pivoting valve is accomplished by an operating mechanism from either side of the railway car.

Abstract: A drink dispenser spigot comprises a barrel, a valve plunger, a stem for the plunger, and a spout opening in the barrel. A splash deflector collar about the stem is movable therewith. As the spigot is opened by withdrawing the plunger so that it passes over the spout opening to dispense drink, the splash deflector at least partially blocks splashing of the drink through the spout opening and into the barrel. Some drink splash may enter the barrel but the splash deflector has a wiper flange which will wipe interior surfaces of the barrel as the plunger moves toward closed position and wipe drink splash from the inside of the barrel and out through the spout opening.

The roof is hinged to a longitudinal listel rigid with said one side wall, inwardly protruding from the longitudinal upper edge of the latter at 90.degree., and is disengageably coupled with a similar listel on the longitudinal upper edge of the other side wall. Both side walls have their longitudinal lower edges hinged to the base wall of the container, the said one side wall being hinged at a level lower than that of the hinges of the other side wall. The container is collapsable to a reduced volume by first folding the end walls onto the inner face of said one side wall, subsequently downwardly folding the roof onto the folded end walls, then downwardly folding onto the base wall said one side wall with its carried end walls and roof, and downwardly folding the other side wall onto the said one side wall.

Abstract: A valve controlled multiple port nozzle device is provided for co-injection molding to sequentially and simultaneously feed a plurality of plastics material melts into a mold. The nozzle device is especially adapted for initially feeding a skin melt followed by a simultaneous feeding of the skin melt and core or foamed melt and then followed by a final skin melt feed into a mold for producing a molded article with a core surrounded by a complete skin. The nozzle device has a single needle or pin valve controlling flow through the nozzle orifice and sequentially opening the orifice to flow from two inlet ports. The needle or pin has a blind bore selectively communicating with one of the ports as it is retracted from the nozzle orifice and spacers are provided to vary the gap between the needle valve tip and the orifice relative to the opening of the blind bore to its port.

Abstract: A valved closure for a disposable drinking receptacle containing a consumable beverage is disclosed. The valved receptacle closure comprises a thin plastic cover having a peripheral groove adapted to sealingly engage with the rim of a drinking receptacle and a drinking opening therein through which the beverage is consumed. A slide valve is received in a recess formed in the cover and is movable into a closed position over the drinking opening. A releasable latch mechanism cooperates with the valve to secure the valve in its closed position against the force of a resilient member, such as a spring. When the latch is released, the resilient member urges the valve into its open position exposing the drinking opening to permit drinking therefrom.

Abstract: Disclosed is a device which permits a plurality of fluids to be received in a mixing chamber simultaneously through nozzles from fluid input chambers. Actuation of a fluid cylinder opens valves so that the fluids are received under pressure in the input chambers. A second fluid cylinder then opens the mixing chamber so that the nozzles emit both fluids simultaneously which mix by impingement and thereafter are dispensed from the mixing chamber. When the valves are closed recirculation is accomplished through a plurality of ports, thereby allowing the fluids to remain at desirable temperatures and viscosity.

Abstract: An actuating mechanism for a locking lid, capable of completely clearing an opening in a vessel and which, in the closed position, is flush with the inner wall of the vessel. The actuating mechanism comprises a sleeve which slides over a fixed rod at an angle of between 0.degree. - 30.degree. with the vessel wall. The sleeve carries at spaced points two pivotally mounted, parallel links of equal length which are pivotally connected to the lid. The lid also carries a guide wheel running in a guide track disposed perpendicular to the vessel wall and one pivotal connection between the sleeve and link carries a connecting rod displaced by a crank provided with an actuating lever. In the initial opening and final closing movements, the locking lid moves perpendicular to the wall guided by the guide wheel running in the guide track and after clearing the opening, the lid moves parallel to itself and is brought back in front of the opening.
