System and a method for constant micro-dosing and feeding of powder material

A system and a method for a constant micro dosing of powder material include a control device, a cylinder with a first opening and a piston movably arranged inside the cylinder and controllable by the control device. The piston is movable in the direction to or away from the first opening along a piston stroke direction. The cylinder stores the powder material between the piston and the first opening. The piston pushes the powder material through the first opening by moving along the piston stroke direction. Further the system and the method include a removing device for removing the powder material which is pushed out of the first opening of the cylinder. The control device controls the piston and the removing device in a synchronized manner such that a predetermined amount of powder material pushed through the first opening is removable by the removing device.

Digital Dispense System

A digital dispense system and method for analyzing samples. The system includes a fluid droplet ejection system housed in a compact housing unit. The fluid droplet ejection system contains a fluid droplet ejection head and fluid cartridge containing one or more fluids to be dispensed, a cartridge translation mechanism for moving the fluid droplet ejection head and fluid cartridge back and forth over a sample holder in an x direction; and a sample holder translation mechanism for moving a sample back and forth beneath the fluid droplet ejection head and fluid cartridge in a y direction orthogonal to the x direction. A digital display device is attached to the fluid droplet ejection system for displaying fluid volume information to a user. The fluid volume information is selected from relative fluid volume, absolute fluid volume, and a combination of relative and absolute fluid volumes.

Measuring adapter assembly for closed loop fluid transfer system

A measuring a closed-loop fluid transfer system is provided that includes a measuring adapter having a first end and a second ends, and a chamber located there between and configured to hold a volume of fluid. The measuring adapter includes a first receiving valve assembly located at the first end of the measuring adapter. The first receiving valve assembly includes a receiving valve member, at least a portion of which is separable from a portion of the first receiving valve assembly. This creates an opening that provides fluid communication to the chamber when a force is exerted on the receiving valve member of the first receiving valve assembly. A second valve assembly located at the second end of the measuring adapter includes a valve member. At least a portion of the valve member of the second valve assembly is separable from a portion of the second valve assembly to create an opening that provides fluid communication to the chamber.

AUTOMATIC DISPENSING SYSTEM

A dispensing device for dispensing material. The dispensing device comprises a dispensing head; a capsule magazine including at least one void; at least one material capsule, wherein the at least one material capsule is disposed within the at least one void in the material capsule magazine; a motor, operable to provide mechanical power for material dispensing operations, wherein the motor is disposed within the dispensing head; and a gear mechanically connected to the motor, wherein the gear is further disposed in connection with the at least one material capsule, such that operation of the motor causes rotation of the gear and, in turn rotation of the at least one material capsule.

AUTOMATED DRY GRANULAR MATERIAL DISPENSER
20210252528 · 2021-08-19 ·

An automatic dry material dispenser for dispensing dry material such as fertilizer to pots or other containers passing by on a conveyor. The device is controlled by a photo-detector or mechanical switch to dispense material when the container is in the proper position. The device consists of a material reservoir, a flexible feed hose, a pipe and elbow which can be pivoted by an electric solenoid and electronics for control. As the pipe and elbow are pivoted to a stop by the solenoid material is expelled from the elbow and down into the passing pot. The amount of material dispensed is controlled by an insert-able cylinder and by selecting the number of dispensing cycles per pot.

Fill needle system

The present invention involves a fill needle system for aseptically dispensing a pharmaceutical fluid in an aseptic chamber comprises a fill needle tubing in fluid communication with a pharmaceutical fluid source via flexible tubing and extending through a fill needle hub; a fill needle dispensing tip disposed at a dispensing end of the fill needle tubing; a fill needle sheath shaped and arranged to removably mate with and seal aseptically to the fill needle hub to form an aseptically sealed volume enclosing the dispensing tip; and a fluid pressure pulse induction system disposed and configured to compress the flexible tubing in order to dislodge droplets of pharmaceutical fluid retained on the dispensing tip after halting dispensing of the pharmaceutical fluid. An associated method of dispensing pharmaceutical fluid comprises operating the fluid pressure pulse induction system to dislodge the droplets. The system may comprise a controller for automatically controlling the dispensing and droplet dislodging.

Metered fluid dispensing system
