Abstract: Some paste or liquid products, used as cosmetics and medicines, for example, have to be protected from contact with air. Methods have been developed for vacuum packaging them. These methods are more concerned with eliminating air that may remain in the packaging filled with the product at the time the latter is closed (by welding, by sealed fixing of a dispensing valve, etc). No special precautions are taken during filling of the packaging which is carried out in air and inevitably causes unwanted air bubbles to be trapped. The present method avoids any inclusion of air in the product. The packaging, which consists of a variable volume reservoir, is filled while in its maximum content configuration in an hermetically sealed enclosure that is evacuated. The enclosure is formed by a bucket receiving the reservoir and to which a bell fits in a sealed way. The bell is connected to a system of vacuum pumps and to a store of the product.

Abstract: A valve is provided for filling containers which eliminates splashing and dripping. As the container is being filled, the valve is moved upwardly so as to be a set distance above the level of the contents of the container during filling. In addition, the liquid passes through an anti-splash screen as it exits the valve. In a further feature, associated with the screen are one or more suction units which operate at the cessation of liquid flow from the valve to remove liquid from the screen and preventing dripping. The combination of the valve moving upwardly during container filling, a screen, and suction units associated with the screen function to prevent splashing during filling and dripping after filling.

Abstract: A filling nozzle for use in filling a valve bag eliminates sifting of product during and after the filling operation. A body member, adapted for insertion into the valve sleeve, has a material passage therethrough adapted to direct a stream of product emerging therefrom through the valve. A vent is provided, connected to a first conduit, for continuously drawing a low vacuum between the nozzle and the sleeve, both during and after the filling operation, to remove any product particles there present. A second conduit is provided for introducing a high pressure blast of air into the material passage to remove any product remaining therein after a bag has been filled. Finally, a third conduit is provided for drawing a high vacuum in the material passage to remove any particles remaining therein after the filling operation has been completed.

Abstract: A method is disclosed for repeatedly and accurately depositing predetermined amounts of fluid, especially biological fluids, onto generally planar analysis slides. Fluid is aspirated into a disposable metering tip which is rapidly moved into a metering position where the fluid is expelled onto a slide. During movement of the tip into the metering position, a partial vacuum is created on the fluid in the tip, causing the fluid to be drawn up into the tip and thereby preventing fluid from being prematurely expelled onto the slide.

Abstract: A pneumatic valve bag packer provided with an air feed to the hopper that includes an eductor pump having its inlet connected to the hopper so as to produce a subatmospheric pressure in the hopper and consequent reverse air flow in the filling spout when the discharge of the eductor pump is open. The arrangement is such that the closure of the pump discharge by a valve provided for this purpose will result in superatmospheric pressure in the hopper suitable for bag filling. Abrupt opening of the pump discharge causes a vacuum pulse within as well as a sustained low pressure in the hopper so as to promptly stop and prevent material dribble from the filling spout.

Abstract: An apparatus and method for gravity molding articles such as battery straps or the like in open or non-pressurized molds. The apparatus uses an upwardly inclined molding head including a molten metal reservoir and a nozzle discharge end positioned adjacent the mold for delivering molten metal into the mold. Delivery of molten metal can be from a molten lead vat through a siphon conduit and stop-cock valve at the mold head. At the end of each pour, upon closing of the stop-cock valve, a small amount of molten metal is withdrawn from the heated reservoir into a suction system to decrease the level of the reservoir slightly below the lower lip of the nozzle end and thereby prevent dripping from the nozzle end between pours. At the beginning of each pour, the molten metal is released from the suction system back into the reservoir for use in the pour.
