The present invention relates to a bioreactor including at least one reactor vessel in form of a plastic bag, a tray () for holding said at least one bag, a rocking device for limited rocking motions of the tray () around a rocking axis (). According to the invention the bioreactor comprises a device () for enabling swinging of the tray () around a second axis () parallel to and distanced from the rocking axis ().

A filter heater arranged to enclose a filter, wherein said filter heater comprises two similar halves each having a protruding handle on one side, whereby the handles are kept together by a spring mechanism such that pinching the handles towards each other will force the sides of the two halves opposite the handles from each other.

A method and an arrangement in a data communications system. The object of the invention is to achieve a wireless communication between a processing unit and a printer using a safe transmission and an increased transmission range compared to the infrared transmission. The solution is a way of printing a document in a data communications system using a protocol profiled for printing in the Bluetooth protocol architecture.

Method, and arrangement in a communications network

A rotatable tool includes a shaft and a cutting head mounted thereto. The shaft defines a longitudinal axis of rotation and has a seat formed at a front end thereof which includes a first engagement surface. The cutting head is attached on the seat and includes a second engagement surface engaging the first engagement surface for longitudinally locking the cutting head to the shaft. The first and second engagement surfaces include respective first and second support surfaces which together form a planar interface, the interface defining a contact line when viewed longitudinally toward a front end of the tool. The contact line intersects an outer periphery of the cutting head at a point. The contact line extends from the point in a direction forming an acute angle with a radius that intersects the point. The contact line is disposed rotationally ahead of the radius with reference to rotation of the tool. The cutting head is attached to the shaft in response to relative rotation therebetween, whereupon respective longitudinal undercuts formed by the support surfaces engage one another, and a snap action occurs between respective portions of the engagement surfaces, to resist longitudinal and rotational dislodgement of the cutting head.

A tool for rotating a cutting head relative to a shaft includes a pair of identical L-shaped shanks. Each shank includes first and second parts oriented transversely to one another, with a shoulder projecting from the first part into a corner formed by the first and second parts. A free end of each first part includes a through-hole receiving the second part of the other shank, wherein the shoulders face one another in order to be able to grip a cutting head. Each second part is slidable in its respective through-hole to enable the distance between the shoulders to be adjusted to accommodate different-size cutting heads.

Tool for rotating cutting heads

A rotatable tool has a replaceable tip mounted thereon. The tool includes a tool body having a cutting seat in which the tip is received. The tip has edges for chip removing machining. The cutting seat and the replaceable tip have mutually cooperating support surfaces extending transverse to the longitudinal center axis of the tool. The cutting seat and the replaceable tip have mutually cooperating guide surfaces which are symmetrical about the longitudinal center axis as well as clamp portions for clamping the replaceable tip in the axis direction of the tool. A locking screw is received in the tool body to bring the replaceable tip into cooperation with the clamping portions.
