The flow rate of the gas can be controlled by adjusting the protruder that projects from the window of the body portion.

Abstract: A fluid discharging device has a cylinder having a first valve at one end of a suction chamber, and a cylindrical piston movably mounted in the cylinder. The piston has a second valve and a suction opening. A resilient element such as a coil spring is mounted between the cylinder and the piston so that the piston is generally biased against the cylinder. This valve mechanism is disposed in a collapsable container which contains a fluid. The cylinder is connected to an opening of the fluid container so that the first valve is exposed. The fluid discharging device can be disposed within a casing which has a refined appearance and includes an actuator for manually actuating the valve mechanism.

Abstract: A metering mechanism comprises a housing (7) with a material inlet (12) and a rotary metering member (27) that is rotatably mounted between side walls (8,9) of the housing with its periphery exposed to a chamber (48) within the housing so as to meter material from the chamber as it rotates, characterized in that a removable insert (74) is provided that is a close fit in said chamber and has a passage (75) through it that communicates at one end with said inlet (12) and at the other end with the periphery of the rotary metering member (27) so that the effective volume of said chamber (48) is reduced to the volume of said passage (75). Thus, if the metering mechanism incorporates the known shutter-type tramlining device in which a shutter (24) serves to close the inlet (12) to the housing, the quantity of speed retained in the chamber within the housing is reduced and therefore the length of a bout that will be sown after closing the shutter will be correspondingly reduced.

Abstract: A flavor dispensing device usable on machines for dispensing frozen foods, such as ice cream. The flavor dispensing device is suitable to be retrofitted on existing food dispensing machines below the dispensing spigot. One embodiment includes a syrup stem protruding inwardly into the food/flavor mixing chamber. This stem may have both an opening in the central portion and the perimeter portion of the mixing chamber, resulting in syrup being deposited in the center and the perimeter of the ice cream flow. A rotor in the chamber provides mixing, and in one embodiment the rotor is tangentially driven and has a central aperture therein. A water flush system is provided to clean syrup and food from the various lines and ducts. The flavor dispensing device is readily removable for cleaning and servicing.

Abstract: A tube for continuous casting of molten metal is composed of a thin sheet-metal cladding and of an internal lining of heat-insulating material which is sinterable at the casting temperatures involved.

Abstract: A tap for use with a container closure of the type having a pair of resilient sealing plugs. The tap includes a body which supports spaced product and gas tubes adapted to be thrust through the resilient sealing plugs of the closure. When the tap is removed from the container, the gas tube separates from the tap body and remains in the respective sealing plug so as to vent pressure in the container safely to atmosphere. Stabilizing fins extend downwardly from the tap body and engage the top of the closure to help hold the tap in a secure vertical position on the container.
