The invention relates to a punched blank for a tray-like package. It comprises a bottom part (1), two long sides (2) and two short sides (3) in one piece with the bottom part (1) and marked with respect to this by fold lines. The invention is characterized in that the fold lines (7) between the bottom part (1) and at least the long sides (2) are directed outwardly at the ends and form an angle with the middle part (6) of the fold lines of 2-20 DEG .

The invention relates to a fluorescent covering for roads, parking areas etc., which fluoresces upon illumination with ultraviolet light. It comprises organic optical whiteners and pigments, and is characterized in that the binder consists of a solid solution of an amorphous polymer mixture having a glass transition temperature of 20 DEG C to 60 DEG C and a coefficient of elasticity which is less than 1000 MPa at -10 DEG C and greater than 1 MPa at +60 DEG C and which fluoresces upon illumination with ultraviolet light.
摘要:
The present invention relates to a linear block polymer which is particularly suitable for use as an implant in humans or animals, for example as ligaments. The block polymer comprises urea and urethane groups and has a molecular weight of at least 104 Dalton, preferably at least 105 Dalton and it also includes primary NH¿2? and/or OH end groups. Besides the use of the block polymer as an implant in a biological environment, the invention also includes a method for the production thereof, which method is characterized in that a prepolymer having two isocyanate end groups per molecule is chain extended with an aliphatic or aromatic diamine with a mol ratio NH2/NCO of 0.95 to 1.05.
摘要:
A system and method for producing and maintaining a predetermined proportionate mixture of two fluids, such as water and foam concentrate, in accordance with conductivity measurements of the fluids. A set point is established which is representative of the conductivity of the predetermined proportionate mixture. The conductivity of the mixture is measured and compared with the set point by conductivity probes and a microprocessor. A control valve is continuously adjusted to maintain the predetermined proportionate mixture in response to control signals from the microprocessor in accordance with the comparisons of the conductivity values.

The invention relates to a swivel connection intended to be mounted on a robot arm and further intended to carry a welding jaw or something else such as a gripping device. The swivel connection is also intended to have the ability to transfer liquid or gaseous media. It is characterized in that it comprises a rotatable cylindrical hub (6) having an attachment piece (7) at one end for being mounted to a robot arm or the like, a non-rotatable coupling sleeve (10) around the hub (6), a pair of concentric contact rings (12, 13) isolated from each other and from the coupling sleeve and a cover (15) at the other end of the hub (6) around which two from the cover electrically isolated concentric rings (17, 18) are arranged adjacent to the two concentric rings (12, 13) around the coupling sleeve (10). Channels (11) for supply of air and liquid are further arranged in the coupling sleeve (10), the hub (6) and the cover (15) with the rings (17, 18).
摘要:
Expandable shaft for winding elongated material, especially soft paper and other nonwoven material. The shaft (10) has a number of radial openings (13) or grooves (22, 24) which house longitudinal blades (23), bars (11) or the like in such a way that these are movable by means of activating means (14, 15, 25) in a radial direction between a retracted and a projected position, whereby a variable effective diameter of the shaft is created. The radial openings (13) or grooves (22, 24) are arranged with a spiral formed inclination in the longitudinal direction of the shaft (10) and the retractable and projectable blades (23) or the bars (11) housed therein are arranged with a corresponding spiral form along the shaft.
摘要:
A telephone communication headset for attachment to the outer ear of an operator and comprising a main unit (3) which supports an arm (2) with a microphone (1) at its outer end, and an earphone (5) on the main unit. Furthermore, a U-shaped support (6) is arranged with a first and a second downwardly-directed shank, said support (6) being attached to the main unit. A connecting upper portion (9) is arranged between the two shanks, which portions is arranged, in a position of use, to rest against the uppermost point of the outer ear, where the outer ear attaches to the skull. A weight (11) is arranged so that its mass and leverage presses the rear shank (10) of the support (6) towards the rear side of the outer ear and into the fold between the outer ear and the skull. The effect of gravity on the microphone (1) and the microphone-arm (2) is also counter-balanced. The telephone headset is hereby held in position by the pressing action of the rear shank and the torque about said suspension point by way of gravity.
