Abstract: The device includes a housing having an inlet opening which supplies fluid essentially tangentially through a short passage to a chamber being approximately spiral-shaped. The chamber surrounds the axis of a discharge opening located in the bottom of the housing. The spiral chamber imparts an angular momentum to the fluid causing the fluid to flow evenly down the inside face of the outer wall of the container.

Abstract: Nozzle for blowing molds or cores for sand casting where the sand is injected under pressure into the core boxes. The injection orifices in the plate of the machine for blowing sand under pressure into the core boxes are threaded holes onto which are screwed closely coiled spiral springs forming injection conduits, the injection nozzles being screwed onto the said springs by means of threaded holes of suitable diameter and thread.

Abstract: This device for rapid and extremely accurate filling of bottles includes means for decreasing the dispensing flow rate during particular phases of each fill. This feature minimizes foaming of dispensed fluids when the filling operation proceeds into the portion of each bottle wherein conditions are conductive to foaming, while maintaining a rapid fill rate for other portions of each bottle. The device also has a novel spool valve for control of flow between supply, metering device and bottle: this valve has a hollow-centered spool, the hollow center providing in one operational configuration a fluid-flow bypass which reduces the number of ports and connections outside the valve barrel.

Abstract: An apparatus for mending surface irregularities of wooden plates such as those of plywood is provided. Recesses on a plate are automatically filled with putty by this apparatus. Putty is pressurized and the filling of the recesses therewith is controlled by a plurality of needles provided to detect these recesses. In this way, irregularities on a plate are effectively and automatically smoothed regardless of their shape or size.

Abstract: This invention relates to a deflector which is specifically utilizable with a receptacle having a plurality of openings for receiving one or more interconnecting tubings. The deflector includes a plate-like member which is sufficiently large to effectively block a first opening in the receptacle. The plate-like member is biased to a first position to block the first opening in the receptacle. An engagement or abutment member is arranged to project into a second opening in the receptacle to engage or abut the tube which is deflected by said plate member into the second opening in the receptacle. When the abutment member is abutted by a tube, the abutment member rotates around a given axis. The abutment member is appropriately connected to the plate-like member to cause this latter member to also rotate about the given axis such that the plate-like member is removed from blocking relationship relative to said first opening in the receptacle.

Abstract: A liquid dispenser having a liquid flow duct through which liquid may flow from a liquid source into a battery or the like. The dispenser includes a light-transmitting portion adjacent the flow duct to produce a visual indication of the surface elevation of a pool of liquid into which the liquid flows. Available light at the outer end of the light-transmitting portion passes in and through the latter to a reflective, inner end of the light-transmitting portion and is then reflected back out to provide a visual indication that the reflective end is not immersed in the pool of liquid. When the level of the pool has risen to immerse the reflective end, the available light reaching the reflective end is refracted into the liquid, and immersion is indicated by the relative absence of reflection.

Abstract: An automatic battery filler for adding distilled water to storage batteries, comprises an airtight closed water vessel with a spout having a discharge outlet. A spring-loaded valve has a valve stem that protrudes from the end of the spout. Means are provided to adjust the distance between the end of the valve stem and the outlet of the spout, thereby to predetermine the level at which the container will be supported on the battery by the valve stem when the valve is fully open, which in turn will predetermine the level to which the battery is filled. The adjustment is preferably effected by rotating a screw-threaded connection. The socket or the spout has a graduated scale which indicates the level to which the apparatus has been adjusted.

Abstract: A device for metering the flow of a fluid, such as a lubricating medium, at a controlled rate. The fluid is stored within a reservoir having a resiliently expandable wall which maintains the fluid under pressure. A transparent cover is provided for visual observation of the wall to indicate the volume of fluid in the reservoir. The pressurized fluid is directed from the reservoir through an elongate flow passage having a cross-sectional area which is sized in relation to the passage length to establish a predetermined rate of fluid flow. In one embodiment the device is automatically energized upon threading engagement with the opening of a structure to be lubricated, and can then be disengaged and stored in a partially full condition. In another embodiment the flow rate can be readily varied by changing the length of a circular flow passage, or the device can be energized or de-energized, by rotating the transparent cover.

Abstract: Disclosed is a fueling receiver adapted for connection to a tank. The receiver includes a body member which is affixable to the tank. Pivotally attached to the body member is a nipple member which includes a nipple for receiving a fuel nozzle and a fuel shut-off device operable responsive to a predetermined liquid level in the tank to automatically shut-off the flow of fuel from the nozzle through the receiver and into the tank to prevent over-flow of the tank.

Abstract: A multi-purpose funnel with handle, a flanged rim to prevent overflow and a discharge spout. The funnel comprises two co-axial connections with male thread, the smaller diameter connection having a tubular extension and a rubber seal. Discharge pipes are provided, there pipes can be bushed into the connection spout.
