A method and system are provided for preparing micro-ingredient feed additives for use in designated feed rations. A micro-ingredient system of the invention includes a plurality of bins that store designated micro-ingredients therein. A master controller of the delivery system provides signals to control system components based on programmed commands corresponding to micro-ingredient batches to be prepared. Slide gate mechanisms are used to prevent loss of micro-ingredients delivered to a receiving receptacle of the system. During delivery of the micro-ingredients to the receptacle and during processing, the micro-ingredients can become airborne and subsequently lost. The slide gate mechanisms also provide controlled access to the receiving receptacle to prevent system errors such as contamination of ingredients in the receptacle, or improper batching of a prescribed micro-ingredient mixture to be delivered to a designated feed ration.

[Problems] To provide a driving method for a metering pump, a driving apparatus for a metering pump, a vaporizer and an anesthesia apparatus which are capable of suppressing a pulsation in the metering pump, and lowering the costs and reducing the sizes of the vaporizer and the anesthesia apparatus.

[Means for solving the Problems] A metering pump 16 is joined to the stepping motor 15, includes an eccentric mechanism converting a revolving motion of the stepping motor 15 into a reciprocating motion of a plunger 16A, and makes a constant liquid delivery by sucking and discharging an anesthetic agent through variations in the cubic volume of a cylinder 16D caused by the reciprocating motion of the plunger 16A. The control section 12: calculates a suction and discharge cycle T of the metering pump 16 on the basis of a set anesthetic-gas concentration and a fresh-gas flow rate; sets a discharge period T2 of the cycle T to be longer than a suction period T1 of the cycle T; and controls the revolution speed of the stepping motor 15 so that the travelling speed of the plunger 16A is kept constant during the discharge period T2.

A blender has a tubular mixing chamber that is provided with an interior and is arranged horizontally. A fill opening and an outlet opening communicate with the interior of the tubular mixing chamber. The fill opening and the outlet opening are spaced apart from each other in an axial direction of the tubular mixing chamber by a length distance. A rotatably driven shaft extends in the axial direction lengthwise through the interior of the tubular mixing chamber and is provided with mixing members that are projecting radially outwardly into the interior of the tubular mixing chamber. The shaft has a region without mixing members, wherein the region without mixing members is located in front of the outlet opening and adjoining the outlet opening. The region without mixing members has a length that amounts to between ⅕ of the length distance and ½ of the length distance.

An apparatus for dye dispensing is disclosed herein. The apparatus includes a controller and a tray. The tray communicates with the controller and is configured with at least one opening. At least one canister is configured with an identifier and a dye. The dye is associated with the identifier. A reader communicates with the controller. A dispenser comprises an actuator communicating with the controller and a lever arm. The lever arm is coupled to the actuator and configured with a projection. The reader, based on the identifier, identifies a selected dye in a selected canister associated with a dye formulation. When the selected canister is aligned with a dispensing area, the dispenser applies a downward force on the selected canister and dispenses the selected dye.

A container with two inner chambers (6, 7) running in its longitudinal direction and separated by at least one partition wall. An aerobic adhesive is stored in one inner chamber (6). A hydrophilic, gel-like activator is stored in the other inner chamber (7); a mixing unit can be attached to the front end of the container. The aerobic adhesive is fed to the mixing unit from the first inner chamber (6), and the hydrophilic activator is fed to the mixing unit from the second inner chamber (7), in a specified mixing ratio via a supply device and mixed together there. This mixture is discharged via an outlet opening (13) of the mixing unit.

A pump capable of dispensing both a large volume and a small volume of colorant comprises a large reciprocating positive displacement pump having a large reciprocating part, a large pump body and a large pump inlet-outlet opening, characterized in that: a small reciprocating part fixed to the large reciprocating part is disposed in the large pump body; a small pump body is disposed on a base of the large pump body, and provided with a small pump inlet-outlet opening; and the small reciprocating part, the small pump body and the small pump inlet-outlet opening constitute a small reciprocating positive displacement pump. The reciprocating positive displacement pump provided in the present invention may achieve dispensing of both a large volume and a small volume of colorant by means of a large-section pump, and thus guarantees the accuracy of the dispensed volume of colorant, and in particular, the accuracy of dispensing of a small volume of colorant; and the reciprocating positive displacement pump, when compared with the prior art, has the advantages of high accuracy and simple structure, and when compared with the structure in patent No. US2009236367A1, has the advantages of good leakproofness, high utilization of a reciprocating pump cylinder body in the length direction, and improved stroke accuracy of the reciprocating pump due to less elastic deformation of a pump support.

A system can include a dry powder mixing tank, a first powder input, a second powder input, a powder output, and a detection device. The first powder input and the second powder input can introduce powders containing different substances that become mixed in the dry powder mixing tank. The detection device can detect information about amounts of different substances in a blend of powder moved out of the tank by the powder output. In some aspects, portions of the blend that do not satisfy parameters for the blend can be diverted from a receptacle for the blend based on the detected information.

A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.

A system for measurement of quantity (density) of particles/solid materials in wastewater, and dilution of particle quantity based on the intended application. Currently enabling quick and serial measurement of particle quantity in laboratory environment, this system is placed inside the desired step of the process of an industrial facility. This way, the system yields quick results and in turn reduces the analysis and evaluation costs.

A plural component dispensing system individually delivers separate material components to each of a plurality of proportioners. Each of the proportioners regulates volumetric flow of each of the separate material components to produce a target ratio of the separate material components associated with the proportioner. The target ratios associated with the plurality of proportioners can be the same or different target ratios. Each proportioner delivers the separate material components at the associated target ratio to one of a plurality of dispensing devices. Each dispensing device mixes the separate components received at the corresponding target ratio and delivers the components as a mixture.
