摘要:
Methods and devices for preparing a biological sample for analysis are described. The biological sample from an organism has at least macromolecule having a primary structure that naturally degrades after the sample is removed from the organism. The method includes causing the biological sample to adopt a shape to permit rapid and uniform heating. The shaped sample is then rapidly and uniformly heated, thereby altering a secondary structure of the macromolecule while preserving its primary structure.

A device for dispensing a string or dab of liquid or plastic substance, such as putty, glue, paint or lubricant, to an object includes a pump for feeding the substance through a conduit to a nozzle having a fine discharge opening. A booster is connected to the conduit between the pump and the nozzle and a pressure medium is supplied to the booster. A substance control valve controls flow of the substance through the nozzle, the substance control valve being connected to the pressure medium and including a valve body which is biased in a closing direction by the substance and which is biased in an opening direction by the pressure medium via an actuator. The actuator includes a pressure member, one side of which is actuated by the pressure medium and the opposite side of which is actuated by the substance, the area of said pressure member being considerably larger than the area of said valve body. The device further includes a pressure medium control valve for controlling the substance control valve.

A machine tool comprising a portal stand having a number of, preferably four, screw pillars and a moveable yoke driven and guided along the screw pillars by means of nuts preferably roller nuts, in the yoke. Tools, machining devices or the like can be attached to the yoke. The nuts are driven simultaneously by a drive motor through a drive shaft extending therefrom. A very good parallel guiding of the yoke is achieved despite uneven loads. When the power demand is high, for example during heavy pressings, an auxiliary cylinder is provided, the piston rod of which is fixed to the yoke.
摘要:
The method and devices are for preparing a biological sample for biological analyses. The biological sample has at least one amino acid sequence from an organism. The amino acid sequence is a subject of degradation. The biological sample is physically prepared to enable altering a secondary structure of the amino acid sequence to a deactivated secondary structure, and altering the secondary structure of the amino acid sequence to a deactivated secondary structure by heating the biological sample.

A method and apparatus for the production of reinforced plastic objects uses a body form around which a casing having a cover is placed. The cover includes two cover units which between them defines an opening having an adjustable size and position. The opening provides access into the body form so that reinforced plastic material may be applied therein. The size of the opening is minimized to reduce the amount of environmentally harmful substances escaping therefrom, such as styrene. The position and size of the opening relative to the body form is adjustable to provide a convenient access into the body form.

A device for storing a biological sample (3) and allowing transfer of heat for disrupting secondary structures of the biological sample (3) is disclosed. It comprises a biological sample carrier (5) having a portion (7). The portion (7) is intended for receiving a biological sample (3). It also comprises at least one sealing means (9, 13, 15) for sealing the portion (7), a heat transfer segment (11) that extends at least essentially through at least one of the portion (7) and the sealing means (9, 13, 15), and presents a ratio between a heat conductivity of and a thickness of the heat transfer segment (11) that is larger than 500 W/m K in order to enable heat transfer to the biological sample (3) via the heat transfer segment (11). Also, a method for preparing the biological sample (3) is disclosed.

摘要:
A device, potentially implantable in a living organism, intended to utilize at least a part of the hydraulic energy generated by the heart (10)—the primary unit—at the natural phases of work when the cavities of the heart (11, 12 and 16, 17) are filed with blood. The device includes at least one secondary unit (24), which is connectable to the cardiovascular system of the organism and arranged to utilize said hydraulic energy. The secondary unit is represented by at least one hydraulic motor (24a) arranged to transfer the hydraulic energy to a transferal organ (28). The transferal organ (28) is arranged to influence at least one tertiary unit, for example an executive device (29), which is constructed in order to convert the transferred energy to an alternative form of energy, with the purpose to influence certain defined functions within the organism. Preferably is arranged a regulating device (30) in order to control running parameters of the unit.
摘要:
A device for sterilization of instruments, particularly dental instruments, in an autoclave provided with an instrument holder. The autoclave has an inlet and an outlet for different fluids, such as cleaning and rinsing liquids, and sterilization and maintenance media. The autoclave incorporates several gas-tight closable chambers each of which is equipped with at least one instrument holder. Each chamber and instrument holder is provided with an individually adjustable and controllable inlet and outlet for the fluids and media. Each chamber, as a result of the autoclaving process, defines a sterile package in the form of a closed storage vessel for at least one treatment instrument. The chambers are connected to a central unit for choosing a sterilization program, depending upon the exposure of the instrument outside the autoclave, as well as preparing and controlling the fluids and media.
摘要:
A method for conveying and depositing an adhesive, flexible material by way of a flexible base in right side up position which essentially maintains it shape in a deposition station. The base is supported by a displaceable supporting device equipped with a guiding member, which imparts a direction change to the base. The supporting device at the deposition moves the base away below the material causing the material to be deposited by means of free fall. The material is positioned on the base a distance from the delivery end of the supporting device corresponding to the acceleration distance of the base. The rear end of the base is fixedly attached against displacement. The base is urged to make an abrupt direction change over a guiding member having a very small curvature radius (r) at the front end of the supporting device. The supporting device and the base are simultaneously accelerated rearwardly at an acceleration, which should be at least 1 g.
