The invention concerns a cutting device () for reducing the width of a ready-made roller blind blank () comprising a roller tube onto which a fabric has been wound. The cutting device () comprises a mandrel (), which is adapted to be inserted into and hold an end to be cut of the roller tube, and a knife arrangement, which is adapted to circumferentially cut first the fabric wound on the roller tube and then the roller tube on the mandrel () such that the width of the ready-made roller blind blank () is reduced. The invention also concerns a ready-made roller blind blank (), which comprises a roller tube, onto which a fabric has been wound and which is adapted to be cut by means of a cutting device () according to the invention. For this the roller blind blank () comprises a disposable wrapping, which bears a visible measurement scale along at least one end portion of the roller blind blank ().

Cutting device

The present invention concerns a device () for preloading of a rewind mechanism () for a fabric () arranged on an elongated tube () or the like of a roller blind, a projector screen or the like. The rewind mechanism () is arranged to be essentially inserted into said tube () and includes a spring (), that is tensioned when the fabric () is rolled out and relieved when the fabric () is rolled up onto the tube (). The device () includes an outer mounting element (), that is arranged to be attached to the tube (), and an inner mounting element (), that is arranged to be attached to an outer bracket (not shown), said mounting elements () being rotatingly arranged in relation to each other about a longitudinal axis of said tube (). A spring element () is arranged between said mounting elements () and includes a sleeve (), in which said spring () is arranged. The sleeve () has an inner diameter that is smaller than the outer diameter of the spring () in an untensioned condition, wherein said spring () is arranged inside the sleeve () by being inserted therein in a pretensioned condition.

An interactive method of presenting information in an image to a user, who carries a head-mounted display device that presents an image of the surroundings. The user's head position and direction are established in relation to the surroundings and a calculating device establishes, based on this, which part of the surroundings is positioned in front of the user's head. Furthermore, the calculating device establishes where in a chain of information the user is positioned and, based on this, presents information in the form of a virtual image which is mixed with the real image. A central part of the image is then defined and fields and/or objects outside this area are shown in a non-disturbing way until the user's gaze has left the central part. The user informs the calculating device that he/she has received the information and, respectively, performed the current operations by looking at the fields/objects.

Implantable occluder for a body duct

An implantable device for occluding a body duct, especially a blood vessel. The device includes a flexible, elongate plate to be fixed around the duct, a plurality of communicating bulbs which are arranged on one side of the plate and have a variable volume, and a connection for supplying fluid to the bulbs for occluding the duct and for evacuating fluid from the bulbs to open the duct after the occlusion. The flexible plate has a perforation at one end and a locking member in the form of a thickened portion at the other end. The locking member is passed through the perforation for safely fixing the device around the body duct. To improve the occlusive function of the device, the bulbs may be made of an elastic material, the thickness of which is smallest at the tops of the bulbs.

A shade roller latch comprises a latch member in a bore in a stationary stem. This latch member can fall by gravity into a notch in the inside circumferential surface of a shell rotatable with the shade roller to be received in part by this notch and lock the roller against rotation in relation to the stem.

A ball clutch mechanism in a spring motor for a tubular roller-blind rod or the like. The clutch includes a hub or outer clutch member rotatably mounted on a cylindrical portion of a shaft made of plastics and forming an inner clutch member including clutch ball receiving recesses. The hub has straight ball channels and is made of plastics in one piece. The hub is locked in an axial position on the shaft by a locking pin engaging a groove in the shaft. The locking pin has a stop arm located to retain the respective clutch ball in the ball channel.
