Abstract: A soft dessert dispensing arrangement in which a dispenser is responsive to manual actuation by an operator to dispense soft dessert over a given time period, as measured by an electrical timing circuit. Changes in important parameters affecting the pumping rate of the dessert, such as the pressure and temperature of the pumped dessert and the elapsed time since the last dispensing operation, are compensated for by adjusting the given time period to provide for the dispensing of a substantially constant quantity of dessert despite the changed parameters. The electrical timing circuit is responsive to an input resistance to measure the given time period, and the resistance applied to the timing circuit changes in accordance with sensed variations in the aforementioned parameters.

Abstract: A tap operated by a push button which acts to open a valve member which is biassed to the closed position, the valve member being for normal operation of the tap; also operated by the push button, but only on initial operation of the push button, is a plugging means which plugs the inlet of the tap and which after the initial operation remains out of the inlet. The arrangement ensures added protection against oxygen penetrating into a container fitted with the tap and is particularly useful for wine containers where the added protection ensures a longer shelf life. The use of a plugging means fitted tap avoids the necessity of special sealing equipment for the containers in the winery where containers are filled.

Abstract: A self-sealing container closure includes a rotatable cap mounted over the mouth of an oval squeezable container. The cap has an outlet opening defined by a valve seat. The outlet opening is sealed by a valve element forced against the valve seat by a valve spring and a pair of actuating arms. An upper end of each actuating arm is non-rotatably coupled to the cap while the lower end is connected to the valve spring. When the cap is rotated to align the actuating arms with the minimum width of the container, squeezing the sides of the container presses on the actuating arms to further deflect the valve spring. This forces the valve element away from the valve seat to open the container. Rotating the cap, to align the arms with the maximum width of the container, places the container in a non-operational mode. Also disclosed is a piston and cylinder arrangement coupled to the actuating arms for dispensing a measured amount of liquid from the container.

Selective rotation of either shaft moves the respective door to cover or uncover the unit openings to regulate ballast discharge.

Abstract: Known apparatuses to inject liquids, in particular plastics into injection moulds have closure rods which remain in the gating when the closure system is opened. In the present apparatus the liquid passage always is completely free when the closure system is opened, because the closure rod can be totally retracted from the liquid passage. This can be accomplished in two ways: either the liquid passage extends in a bended manner or the closure rod has a side view in the configuration of a sector or a circle.
