Automated two step chromatography purification system comprising a, system controller, a capture flow path comprising at least one pump, an elution flow path comprising at least one pump, and a valve arrangement for selective connection of two capture columns to the capture flow path and the elution flow path respectively such that both flow paths may be operated simultaneously and in parallel.

Automated multi-step purification system

A rotary valvecomprising a statorand a rotorwherein the stator comprises a plurality of connection ports (-) and orifices (-) and the rotor comprises a plurality of pairs of rotor valve orifices (-) joined by transfer channels (-). The rotor is able to be placed in different working positions whereby fluids can be fed to, for example, chromatography columns and/or can be bypassed through or around the valve. The invention also relates to a system comprising two components such as chromatography columns and a rotary valve.

Rotary valve and systems

A rotary valve comprising a stator with an inner stator face, and a rotor with an inner rotor face arranged in sealing contact with the inner stator face, the rotor is rotatably movable to a plurality of rotor positions about a rotational axis relative to the inner stator face, the stator comprises a plurality of connection ports each being in fluidic contact with a corresponding valve orifice at the inner stator face and the rotor comprises two or more interconnection paths for selective fluidic interconnection of said valve orifices with respect to the rotor position, wherein the stator comprises, an inlet port, an outlet port, a component feed port, a component return port, and wherein the interconnection paths in the rotor are arranged to: &#x2014;in a first rotor position interconnect the inlet port with the outlet port, &#x2014;in a second rotor position interconnect the inlet port with the component feed port and the component return port with the outlet port, &#x2014;in a third rotor position interconnect the inlet port with the component return port and the component feed port with the outlet port.

Versatile rotary valve

A locking device to be secured in a weapon, comprising a first locking means manoeuvrable by a lock cylinder ( ), which locking means has a friction body ( ) displaceably arranged in relation to the lock body ( ) and insertable into the chamber or barrel of the weapon, and blocking elements ( ) arranged to be moved into engagement with the inside wall of the chamber/barrel in case of mutual displacement between the friction body ( ) and the lock body ( ). The locking device furthermore comprising a second locking means ( ), which by means of the lock cylinder ( ) is movable into engagement with a space in the weapon located adjacent to the chamber/barrel in order to secure the locking device in the weapon. The invention also relates to a locking device having a ring-shaped lock element ( ), a locking device comprising a lock shaft ( ) with a blocking device ( ) for preventing displacement of the lock shaft, a locking device comprising a blocking element and a key ( ) for manoeuvring a locking device.
