The invention discloses a kind of thickening carbon dioxide displacement visual analog device, including pressure boost module, visual stirring vessel module and displacement analog module; the mentioned pressure boost module, visual stirring vessel module and displacement analog module are connected successively; the invention is used to develop the experimental study including evaluation of gas injection miscible-phase/non-miscible-phase displacement efficiency, percolation characteristics during gas displacement, mobility control technology during gas drive, and optimization of gas injection way.

A system includes a dip tube, a feed line, and a check valve. The dip tube is inserted through an opening in a source of chemical precursor and into the chemical precursor in the source. A portion of the feed line is located in the dip tube. The feed line passes out of the dip tube. The chemical precursor is capable of flowing out of the source through the feed line in a downstream direction. The check valve is located in the portion of the feed line in the dip tube. The check valve permits the chemical precursor to pass substantially only in the downstream direction. The feed line is coupled to a transfer pump that draws the chemical precursor out of the source through the portion of the feed line in the dip tube.

A hotplate device has a body with a platform for receiving a vessel that contains a sample to be heated. A heating element, arranged under the platform, provides heat to the platform, based on a set temperature and a measured temperature as sensed by at least one temperature sensor, proximate to the platform. A controller located in the body directs electrical power to the heating element. As a safety feature, a wireless communication feature allows a user to enter set temperature instructions from a mobile device when communication with the mobile device is enabled and established. A proximity feature, when enabled, allows the user to enter instructions only as long as the user remains in a predetermined proximity of the hotplate device.

Presented and described herein is a stroke system (1) for dosing a fluid from a container (3), comprising a piston pump (5) with a piston (7), so that a fluid can be dosed from a container (3) by displacement of the piston (7), and a temperature control device (29) for controlling the temperature of the fluid to be dosed by means of the stroke system (1).

With a method for heating in particular milk or milk foam, in which the milk or the milk/air mixture is conveyed through a passage opening and hot steam is conveyed through at least one steam line transversely into this passage opening. The passage opening and the at least one inlet opening opening transversely into the steam line, the steam pressure in this and the pressure and the pressure in the passage opening with flowing milk or milk/air mixture are so coordinated that the hot steam at the at least one transverse inlet opening condenses in the passage opening directly on contact with the milk or the milk/air mixture. Consequently the additional energy produced by the phase change from steam to condensate water is transmitted directly as heat to the heat in the milk or the milk/air mixture.

A caffeine reduction apparatus includes: a main housing provided with an inlet and outlet pipe; a mixing portion including an accommodating portion through which coffee grounds are input inside the accommodating portion, and a blade configured to be rotated inside the accommodating portion such that the coffee grounds are mixed; a driving portion configured to rotate the blade; and an ultraviolet ray emitting portion positioned at an upper portion of the main housing and mounted at an inner side surface of a door that seals an inner portion of the mixing portion, the ultraviolet ray emitting portion being configured to emit ultraviolet rays toward the mixing portion.

One variation of a mixing system includes: a container configured to store consumable beverages; a lid; and a mixer. The lid is configured to transiently couple to the container and includes: a housing; a mixer receptacle; a set of user controls arranged on an outer face of the lid; a set of electronics arranged within the housing and including a motor, a controller configured to actuate the motor responsive to selection of the set of user controls, and a power supply configured to supply power to the motor and the controller; and a set of supports arranged between the motor and walls of the housing and configured to absorb energy output by the motor. The mixer includes: a connector section configured to engage the mixer receptacle to couple the mixer to the motor; and a mixing section configured to mix ingredients in the container responsive to actuation of the motor.
