| A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber. | ||||||

| A dispenser device includes: a valve system, a dispensing head for dispensing liquid and connected with a transfer tube to the valve system, a dispensing pump connected to the valve system, a first inlet port for conducting rinse liquid to the valve system, and a second inlet port for conducting rinse gas to the valve system. The device includes control equipment for operating the valve system so that the flow via the transfer tube towards the dispensing head includes both the rinse liquid and the rinse gas. The rinse gas is capable of collecting gas bubbles formed on the inner walls of the transfer tube to larger amounts of gas. Thus, the rinse gas facilitates the removal of the gas bubbles with the aid of the rinse liquid. | ||||||

| 70 | METHOD, CONTROLLER, VALVE ARRANGEMENT AND PORTIONING DEVICE FOR PORTIONING A FLOWABLE, OPTIONALLY PRESSURIZED MASS | US13201161 | 2010-02-10 | US20120132284A1 | 2012-05-31 | Leo Bühler |
| A method is provided for portioning a flowable, optionally pressurized mass. In a first step a first pinch valve is opened and a second pinch valve located thereafter in a principal flow direction of the mass (m) is slightly closed. As soon as a desired quantity of the mass has passed the pinch valves the first pinch valve is closed. The second pinch valve is then opened. The opening, the slight closing and the closing of the first pinch valve and of the second pinch valve is accomplished by a pressure medium. A controller, a valve arrangement and a portioning device are also provided for executing the method. | ||||||

| 76 | Fluid volume measuring apparatus with bubble in fluid | US11007287 | 2004-12-09 | US20050126278A1 | 2005-06-16 | Hiroki Tani; Makoto Yamaguchi; Tetsuji Kudo; Koji Mizukusa |
| A fluid volume measuring apparatus for measuring volume of fluid flowing out of a measured object includes a passage member that defines a measurement passage. The measurement passage is filled with fluid, which is capable of moving in the measurement passage in accordance with volume of fluid flowing out of the measured object. The fluid filled in the measurement passage forms a bubble. The passage member has a translucent portion in a predetermined measurement range, in which the bubble displaces in accordance with volume of fluid flowing out of the object to be measured. The translucent portion is formed of a translucent material. Volume of fluid, which flows out of the measured object, is measured in accordance with displacement of the bubble. | ||||||
| 77 | Volumetric pump | US09863966 | 2001-05-23 | US20010052527A1 | 2001-12-20 | Luigi Bassi; Stefano Oggioni |
| A volumetric pump for dispensing a controlled and continuous flow of viscous fluid. The pump according to a preferred embodiment of the present invention can ideally dispense from a minimum of 1 mg/sec to 1 g/sec for fluids with a viscosity from 2,000,000 cps (Centipoise) down to 10,000 cps. Such flexibility in the range of viscosity extends the application fields of this pump to microelectronics as well as automotive and consumer products manufacturing. Two cams mounted with an opposing position of 180null on the same shaft generate an alternate motion of two concentric pistons. The alternate movement of the external piston in one phase pumps out the material through a dispensing needle and allows in the returning phase the viscous fluid to be charged in the dispensing chamber from the feeding container. The alternate movement opens and closes the vents during the different working phases. | ||||||

| A dispensing apparatus for dispensing a material including a valve assembly comprising: a valve member movable in a reciprocating fashion along an axis, where the valve member includes a stem having at least one material transfer recess provided on the stem and a tapered dispensing end having an angle of taper. The valve member is movable between a first position where a discrete toroidal mass of material to be dispensed is formed at the dispensing end and a second position where a discrete toroidal mass of material to be dispensed is not formed at the dispensing end. The dispensing apparatus also includes a material dispensing assembly comprising having a fluid knife for moving the discrete toroidal mass to be dispensed from the dispensing end away from the dispensing end when the valve member is in the first position. The fluid knife is supplied substantially parallel to the angle of taper of the dispensing end. | ||||||
| 79 | Self-priming liquid dispenser | US855198 | 1977-11-28 | US4239131A | 1980-12-16 | Ken Emert; Dan Rogers |
| A container having an opening in its top by which it may be filled with liquid and an opening in its bottom through which liquid may be expelled. The bottom opening is covered by the distal end part of a first rod which is surrounded by a gasket; the first rod is connected to a first piston within a first cylinder. The first cylinder forms a second rod which is connected to a second piston within a second cylinder. The rods and pistons are so arranged that a downward force on the second rod causes the first rod to rise allowing liquid to be dispensed from the bottom opening. | ||||||
| 80 | Non-aerosol type dispenser | US789004 | 1977-04-19 | US4193513A | 1980-03-18 | Glen C. Bull, Jr. |
| The invention employs combination spring and sponge power to dispense fluids and semi-solids from a container. A spring or springs are preferably molded into a compressible foam mass, such as polyurethane, and the combination is then compressed and positioned within a container, along with the material to be dispensed. Expansion provides the dispensing power and additionally serves to fill the void which would otherwise be left in the container as the material is being dispensed. No aerosol type gases are employed. The material to be dispensed may be separated from the spring and sponge by a cup or circular plate. Further, the material to be dispensed, particularly if liquid, may be contained in a plastic bag and the spring and sponge are preferably contained in a plastic bag compressed and sealed and then locked for further venting ot the atmosphere. The evacuation of the bag's contents generally positioned above the spring and sponge will hold the contents in its natural state, as manufactured, until the spring/sponge/bag is vented to the atmosphere through an orifice in the container wall, thus making the container a mechanical pressurized device. | ||||||
