An aerator for liquids, particularly an aerator for water, includes at least one aerating basin and a plurality of immersible elongate bodies, which are contained in said basin and secured to the peripheries of wheels, which revolve about an axis that is parallel to the surface of the liquid in the aerating basin. As a result, each immersible body emerges entirely out of the liquid on one side of the aerating basin and is entirely immersed into said liquid on the other side of the basin. Each im...

Portable holder for liquids intended to be carried over the shoulders which comprises two exchangeable plastic bags, one on the stomach and one on the back, for the liquid, which are firmly secured to a harness, which are connected by means of a tube comprising two nonreturn valves, which prevent the liquid from flowing from one bag to the other. The contents of the bags are consumed simultaneously on consumption of the liquid by suction via the tube or tubes.

An applicator for liquids, especially finger nail treating liquids, comprises a reclosable container substantially filled with a synthetic foam sponge saturated with the liquid contents. The sponge may be slit to accept the insertion of at least one finger tip at a time for application of the treating liquid.

Apparatus for separating a liquid from a stream of another liquid which is immiscible therewith and has a different specific gravity, which apparatus comprises pump means, separator means, and means for feeding the mixture into the separator, the separator means being located on the suction side of the pump means whereby the mixture is drawn into the separator.

A system for significantly reducing the dissolved oxygen content of a liquid. Liquid is pumped from a supply source to a deoxygenation chamber through a line containing a sparger for injecting a gas, such as nitrogen, as bubbles having an average size of not greater than about 5 mm. The sparger is spaced a predetermined distance upstream of the chamber to achieve contact at the bubble interface for a desired length of time. The pressure of the liquid is lowered when it reaches the chamber, relea...

A pump for liquids including a rotor containing bores housing slidable pistons. A stroke member is associated with the pistons and constraining the pistons, when the rotor rotates, to orbit about an axis parallel to the axis of rotation of the rotor. The spacing between the two axes occasions reciprocation of the pistons within their bores to perform a pumping action. Each piston has coupled thereto a U-shaped member within which is engaged a crosshead of the stroke member. The crosshead is mova...

A filter for liquids has a housing, a filtering element accommodated in the housing and having a central tube, and a vibration damper located in the housing and having a membrane, a spring biasing the membrane and a casing arranged to accommodate the membrane and the spring and including a cup-shaped portion which extends into the central tube and receives the spring therein.

An inner container for a composite container for liquids in accordance with the known art, the improvement comprising a flexible bag-like container sealed around its periphery and having two socket members, one having the material of the container extending across its inner end as a frangible diaphragm, and the other providing a frangible diaphragm which, when broken, will permit the container to be filled with liquid, the two sides of the bag-like container being then sealed together to close t...

A weigher for a liquid comprising a receptacle with two compartments alternately tipped into and out of a path of flow for a liquid by a predetermined amount of liquid in one of the compartments. The compartments each have a partition which with higher rates of flow of the liquid causes a higher column of liquid to form in an outer portion of the compartment, which advances the tipping moment and thus ensures that, irrespective of the rate of flow equal portions of liquid are measured.

An injection nozzle for an injection moulding machine is described. The nozzle includes a body having a filter chamber and a filter element removably received in the chamber in the filter body. The outer surface of the filter element is defined by a plurality of slots which extend generally longitudinally of the element in circumferentially spaced positions, and a corresponding plurality of intervening lands. Each slot has a blind inner end and an outer end which opens into an end of the filter ...
