An installation for carrying out a continuous multi-stage industrial process includes a housing that defines a first space and a second space that is connected to the first through a first connecting channel. Different pressure conditions prevail in these spaces during the course of the process. A process material is passed sequentially through the first space, the first connecting channel and the second space. A transported material is provided in the first connecting channel to form a free-flowing sealing zone with the process material and ensures that different process conditions will be maintained in the two spaces, and in particular that different pressures will be maintained in the two spaces. The invention also relates to a multi-stage continuous industrial process using such an installation.

A pulsed compression reactor may include a reactor housing, a spring piston, and a driver piston.

The spring piston may be positioned within the interior volume, wherein the spring piston and the reactor housing at least partially define a perimeter of a gas spring buffer chamber within the interior volume. The driver piston may be positioned within the interior volume, wherein the spring piston, the driver piston, and the reactor housing at least partially define a perimeter of a reaction chamber within the interior volume.

The present invention relates to a pressure vessel (1) for receiving samples (P) to be heated, having a reaction chamber (2) as a pressure space for the initiation and/or facilitation of chemical and/or physical pressure reactions, the reaction chamber (2) being designed for receiving a liquid (5), a magnetic disk (8) mounted rotatably about an axis of rotation in the reaction chamber (2), and a magnet arrangement (10), provided outside the reaction chamber (2), for generating a rotating magnetic field for rotationally driving the magnetic disk (8) about its axis of rotation, the magnetic disk (8) having at least one passage bore (13), which extends transversely in relation to the axis of rotation and is provided in such a way that liquid (5) received in the reaction chamber (2) is driven through the passage opening (13) by rotation of the magnetic disk (8) in order to stir the liquid (5).

A vacuum chamber may include an ambient side and a vacuum side. The vacuum chamber may be configured to carry a feedthrough that may include a hollow tube, a first O-ring captured by a first recess within the hollow tube and a rod extending through the hollow tube. The outer circumference of the rod may be configured to contact an entirety of an inner circumference of the first O-ring. A vacuum fitting having an inner circumference may be fixedly secured to the hollow tube. The rod may be operable to be linearly movable within the hollow tube and may be rotatably movable about an axis within the hollow tube. An object may be secured to the rod and may be linearly and rotatably moved within the vacuum chamber.

A recirculating high pressure lipid extractor includes a kettle with a sealed interior configured for pressurizing and heating a fluid mixture. A flow funnel is positioned in a lower portion. A removable material basket is positioned on top of the flow funnel in an upper section. The removable material basket is configured to hold a material inside the removable material basket. A drain and inlet port is at a bottom of the kettle in communication with the sealed interior of the kettle. A recirculation port is approximate a top of the kettle in communication with the sealed interior of the kettle. Wherein, when the fluid mixture is inserted into the kettle, the recirculating high pressure lipid extractor is configured to pressurize and heat the fluid mixture and recirculate the pressurized and heated fluid mixture from the recirculation port into the drain and inlet port.
