The present invention relates to a device for supporting a number of surface forming elements, for example a floor board or floor panel, in spaced apart relationship from a substrate, for example a bearing floor structure, while permitting air flow in the space between the element and the substrate, characterized in that a beam profile (2) displays one web (3) substantially parallel with the element and the substrate, and interconnecting two webs (4, 5) directed towards the substrate, that said two webs (4, 5) display perforations or through holes (10) for permitting air flow between the element and the substrate transversely of the beam profile (2), and that the ends of said two webs (4, 5) are anchored on and/or in the substrate (1) with the aid of loading forces and/or anchorage means.

An information system for displaying prices of articles on display units adjacent to the location of the articles at a point of sale comprises a number of detached display units, which reproduce information, which is changeable by means of a wireless communication from a central computer or a portable terminal. A problem related to information systems of this type consists in easily and conveniently providing means for assigning an identification code corresponding to a particular article to a display unit. According to the invention this is achieved by a control unit, integrated within the display unit, being able to be set by means of an external switch or signal, the control unit in such set state being arranged to receive and to store an identification code transmitted from the portable terminal.

The present invention demonstrates a method and a device in the technique of using an image sensing member, preferably a CCD cell instead of a film sensitive to X-ray radiation. The method and the device is applicable to a general X-ray arrangement without any necessary direct connection between the image sensing member and the X-ray arrangement has to be present by using a number of detector points for X-ray radiation at or in the CCD cell. Additionally is demonstrated a method and a device resulting in minimizing of the radiation dose to exactly what is needed for exact imaging exposure of an image, which according to the present invention implies that more images may be obtained within a same total normal radiation dose.

The invention relates to a method for harvesting and bundling plants (5), preferably energy forest plants and the like planted in rows, whereby plants, where appropriate from one or several planting rows, in a harvesting assembly (2), during the advancement of the assembly across the ground (15), are continuously gripped by a feeding apparatus (4) and are cut off, and, after having been cut off, are conveyed by the feeding apparatus (4), for further treatment or storing, whereby the cut-off plants are broken at a position (5a) between their ends and are folded around the point of breaking, in a direction towards the subsequent plants (5), for forming a continuous bead (10) of folded plants.

The present invention relates to an arrangement for pivotally attaching an armrest (3), this arrangement including an attachment (2) which is formed integrally with or which can be attached to a chair or like furniture. The armrest (3) has a part (13) which is mounted for limited pivotal movement in the attachment (2). At least that part (13) of the armrest (3) which projects into the attachment (2) has a circular cross section. A part of this circular part (13) has at least one depressed region (16, 17) and located within the attachment (2) is at least one ridge (21-24) which projects into the depressed region (16, 17). The ridge, or ridges (21-24) acts/act as stop means against the end walls (18, 19) of the depressed region or regions (16, 17) such as to restrict pivotal movement of the armrest part (13). The depressed region or regions (16, 17) in the circular part (13) and the ridge or ridges (21-24) have generally the same length and function to lock the circular part (13) against axial movement. Journals for the circular part (13) are provided in the wall through which the circular part (13) projects into the attachment (2) and also in one or more intermediate walls provided within the attachment (2). The attachment (2) is comprised of two halves (11, 12), of which one half (11) can be attached to or is formed integrally with the chair or like furniture, and of which the other half (12) is detachably connectable to the first mentioned half (11).

The present invention provides a method and a device for increasing the coverage in a shop data system for each individual information module (B1 - B10), which has a low output power for its messsage acknowledgement at the reception of information, ensuring that a signal of acknowledgement indicating reception of information reaches a system computer. An information device, for instance a shelf-edge module (B5), which has received a correctly decoded information intended for this particular module, emits a signal of acknowledgement, which then is repeated by said other modules (B1 - B4, B6 - B10), which also have decoded said message finding that it was not intended for them. These modules (B1 - B4, B6 - B10) switch to a repeater mode so that said signal of acknowledgement emitted by said addressed module (B5), will be repeated by each such other module in said repeater mode, which perceives said signal of acknowledgement, said signal of acknowledgement propagating back to said transmitting unit (TX) during a period of time between transmitted messages. Herethrough, it is only required, that each information module has a coverage for its signal of acknowledgement such that this signal reaches at least one other additional information module.

The invention relates to an apparatus for planting cuttings (26a) one by one, comprising a propelled or towed frame supported by rotatable support wheels, a feeding apparatus (16) for cuttings to be planted and intended for bringing the cuttings into contact with a driving means (48) vertically displaceable in a planting tube (17). According to the invention said feeding apparatus (16) is designed for receiving, one by one, cuttings (26a) which have been cut in advance to a length suitable for planting or full shoots (26) or such portions thereof the length of which exceeds the length of a cutting intended for planting; the planting tube (17) and at least one portion (16a) of the feeding apparatus (16) are movable relative to each other, and cutting means are provided in connection with the feeding apparatus (16) and are effective to cutting off a fed, full shoot or a portion thereof during said relative movement, whereupon a cutting (26a) cut off to a suitable length by the relative movement, during the final phase thereof, is brought to a position in the path of movement of the driving means (48).

A duct fan (1) comprises a fan housing (2) consisting of two components, an inlet component (3) and an outlet component (4), a motor bridge (5) placed within the housing, and a unit (6) consisting of a motor with impeller and attached to the motor bridge (5). The motor bridge (5), which is diametrically extended through the housing (2), is provided at its outer ends with lugs (16), which are received in impressions (9) in the edge portion (8) of the inlet component (3). The outlet component (4) is provided with an edge portion (12), which fits onto the edge portion (8) of the inlet component (3), and a shoulder (13) of the edge portion (12) of the outlet component (4) rests, in the assembled state, against the end edge of the edge portion (8) and against the motor bridge (5) at the lugs (16). The outlet component (4) is provided with impressions (14) in positions corresponding to the impressions (9) in the edge portion (8) of the inlet component (3) These impressions (14) form shoulders (15), which are on a level with the shoulder (13) of the edge portion (12) for abutment against the motor bridge (5) at the lugs (16).
