Patent SE-8500905-D0 (SE)
Inventor: ARVIDSSON EWALD
IPC: H05K9/00
Filed: 1985-02-25
Abstract: This invention is a method to reduce the effect of power surge overload during the use of electrical equipment in a steel container (1), and a device to allow implementation of this method. The progress from electromechanical devices to computers has lowered electrical system voltage considerably, which results in increased sensitivity to surges.The problem is solved by placing the equipment (7) in a container (1) with an outer (2) and inner (3) steel shielding that are isolated from one another. The equipment (7) is attached to the inner shielding (3) that is grounded at a considerable distance from the container. The electrically conductive covering (8) on the incoming wire is attached to the container's outer shielding (2), which is grounded in connection to the container (1).<IMAGE>

Abstract: Green mouldings of metal powder and/or ceramic powder are obtained by filling a cooled mould with a mixture of the metal and/or ceramic powder containing 30 to 55% of tertiary butanol as binder. The mixture is at a temperature above the melting point of tertiary butanol, and is cooled in the mould to a temperature below the melting point of methanol. The use of tertiary butanol as binder leads to easy mould release, and since it can be removed from the green moulding at low pressure and relatively low temperature, without decomposition, it is reusable, avoiding the problems of the known decomposable organic binders, and the corrosion resulting from aqueous binders.

Abstract: The disclosure relates to a method for the reliable documentation of two or three-dimensional objects (2) for the purposes of duly establishing, after documentation of the object (2) whether or not a replication or imitation tallies with the object. The object which is to be documented is placed in an apparatus (1) with given coordinates along the x, y and, where applicable, z axes with a given zero position whence these axes extend mutually offset at 90 DEG . Image reproduction of the object (2) is effected by means of at least two reproductions taken by the intermediary of an image reproduction apparatus (10) whose position in relation to the above-mentioned zero position is registered. As images, there are selected, first, an overall view of the object (2) the corresponding position of the overall view in the image reproduction apparatus (10) being registered, and secondly a macroview, i.e. a view of such powerful magnification that individual details in the form of, for instance, droplets, brush hairs down to particle level etc., may clearly be observed and measured, the corresponding position of this macroview in the image reproduction apparatus (10) being registered. These images, all relevant data in the form of, for example, creator of the object (2), owner of the object, the above-disclosed positions, the parameters of the image reproduction apparatus (10) etc. are registered. At least such data as is of importance for the retrieval of the macroview and the macroimage per ce are separated and are protected against unauthorized retrieval.

Abstract: An impulse tool has an air motor connected to rotate a housing that carries a spindle adapted to be connected to a tool. The housing and cavity provide a pulsating force for rotating the spindle and tool to a pre-selected torque limit. When the limit is reached a rod in the housing is moved rearwardly to contact an "L" shaped arm. The "L" shaped arm is moved to release a valve assembly that operates to close off the air supply to the air motor and thereby turn off the tool.

Abstract: The invention concerns a method and a device for preparing a solution, emulsion or suspension of a sensitive medical substance in an aqueous medium, and subsequent injection thereof. In the method according to the invention, a two-chamber barrel ampoule 1 known per se is used for mixing the aqueous medium 11 and the medical substance 10, the aqueous medium 11 being caused to flow smoothly from the bottom upwards through the medical substance 10, avoiding any shaking and admixing of air. The mixing is preferably carried out at a pressure above atmospheric pressure. The invention further concerns an injection device for preparing an injection solution and subsequent injection of the solution. The device comprises a front part 13 which encloses a two-chamber barrel 1 in which the dry medical substance 10 is present, separate from a liquid phase 11, and a rear part 14 which encloses a dosing and administration mechanism 22. When the two parts are screwed together, the liquid phase 11 is mixed with the dry medical substance 10 and brings this into solution, and the finished solution can then be injected, by means of the dosing and administration mechanism 22, through a cannula 17 arranged at the front end of the front part 13. For medical substances which are sensitive to mechanical effects, the invention permits the mixing of the dry substance and aqueous medium and also the subsequent handling of the prepared medium to be done so smoothly that deterioration of the quality of the medical substance through mechanical action is minimized. <IMAGE>

The valve closing member (8 ) is coordinated with a movably mounted plunger element (17), which is disposed at a certain liquid flow through the inlet (3) to lift the valve closing member to its closed position. The plunger element (17) forms a seat (16) on which rests a ball (15), on which ball (15) the valve closing member (8) rests. The seat is formed so that the ball lifts the valve closing member towards the valve seat (13), when the valve housing (1) is tipped from its predetermined position.

Date Apr. 14, 1994A method of discharging particulate material from a first container to a lower positioned storage area being under a lower pressure than the first container. Particulate material is discharged via an upper tube section of a discharge tube communicating with the first container and permanently containing a column of the particulate material. The discharged material is directed into a pressurized stabilizer. The discharged material is directed via a lower tube section to a material feeder for forming columns of the particulate material in the upper and lower tube sections thereby reducing the pressure of the material to a predetermined normal pressure level at the input of the feeder. The material is fed to the storage area. The quantity of discharged material is controlled by the feeder. Gas flowing from the first container is extracted through the particulate material column to an environment via a throttle at an upper portion of the pressure stabilizer, thus stabilizing the discharge by making it independent of pressure variations in the particulate material column upstream of the pressure stabilizer. The feeder is stopped when a pressure increases in the particle column in the upper tube section resulting in a pressure increase in the pressure stabilizer until the pressure of the pressure stabilizer has returned to the normal level due to the extraction of gas.
