Composition for the preservation of wood containing a wood preservative, such as a boron compound or a fluorine compound, in a polymer or polymer composition, which upon contact with water releases the wood preservative. Said composition is introduced into a hole in the wood or in a wood construction, whereafter the hole is sealed.

A fish conveyor comprises saddle-shaped support elements (1) for receiving fish (7) in their belly cavities (9) and for conveying the same past filleting tools. The part of each support element (1) coming into contact with the fish skeleton is formed in such a way that a well-defined alignment is possible so that filleting tools for severing belly and back spokes can be adjusted more closely to ac...

A sheath for deadening the sound of at least one circular blade for cutting marble, granite and hard stone consists of at least one structure of "Bakelite" or other sound deadening material, the structure forming at least one cavity of discoidal shape. The cavity provides a housing for at least one rotating cutting blade. The cutting blade may be provided with teeth along its periphery, thereof. T...

The heat exchanger comprises a number of vertically fitted thin plates (11) of aluminium, copper, or steel. On the plate top edges is a primary group of spreader pipes (12) for spraying the sea water from the energy source on the one side of the plates and a second group of such pipes (13) which sprays a heat absorbing medium such as salt solution on the other side of the plates. In a collection t...

On each of the flat sides of the vessel (1-4) is fixed a second plate (6) spaced from the first. The two plates have different thicknesses and/or vibration characteristics, and are tightly joined along their edges so that a closed space is formed. A medium accommodated in the space produces an acoustic connection between the plates, and can be adhered to them.

The plates are stored in the magazine (10) at different levels and the magazine has tightly adjacent part storage sections (11) with horizontally withdrawable shelf structures. - The transport and lifting equipment comprises a horizontal transporter (16) and means for vertical lifting operations. The transporter is positioned so that a part of it is locked above the position where the shelf struct...

A device for e.g. during anaesthesia to produce an artificial airway comprising a so-called throat tube which has an outlet (12) for implementing a tracheal tube equipped plate for pressing against the patients lips or teeth, as well as an intra-tracheal tube (3) which extends itself down into the patients throat and there is a holder (7) set up at the plate (1) for the tracheal tube. According to...

The table (1), in the work position, is fixed relatively to the machine (7) and a movable input table (2) has its gables forming the front parts of a pair of levers (18) pivotably suspended on the fixed table around a first horizontal rotary axis (10). The levers are counterbalanced by a pair of hydraulic cylinders (20). A second horizontal rotary axis (35) is provided in the feed-in table front e...

The invention refers to a device at a door (6<1>) or other closing element, which presents two piston-equipped bolts at a distance from each other located in the corners of the door in question. The device enables automatic control of the bolts through compulsory force from the outside on only the one bolt. The one, of the said both of the non-rigid force affected bolts (4<1>, 5<1>) presents a gre...

A loading bucket (1) designed to be an accessory to a vehicle such as a loading machine. The loading bucket (1) includes a rotating drum (2), which has opening (12) pointing towards the bucket's (1) mouth (23). The drum (2) is positioned against the bucket's (1) bottom (3) or sidewalls (4, 5) by rollers (13, 14), and the drum's (2) rear bracket (10) is connected via a shaft (15) with a rear bracke...

After the injection pulp has been pumped into the hole, pressure is lowered at the entry point so that the pulp can pass the insert on the way in the hole mouth. This causes a material plug to be formed at the insert which holds the remaining injection pulp inside the insert. The injection used for pumping the pulp into the hole and positioning. The insert can then he removed without waiting for t...

The tensile straightening device described comprises a braking truss (6), a pulling truss (7) and a truing head (8) situated between the two. Each truss has an inner roller (1 resp. 4) and an outer roller (2 rep. 3) the later-named rollers are rotatably mounted on their own rocker frames (9, 10), which are pivotably mounted in the machine stand. The rollers in both trusses can be pressed towards e...
