Inventor: ISOZ PETER
IPC: F41G3/26
Filed: 2001-03-30
Abstract: The invention relates to a method and an arrangement for indicating that a target ( 1 ), such as a vehicle, has been hit. The target is provided with information on the weapon action, and a light source indicates a hit. The information can be made available by direct electromagnetic transmission, for example via radio, or by means of one or more strips ( 9-11 ) with detectors ( 13 ) being arranged on the target ( 1 ). In the latter case, the detectors detect incident illuminating electromagnetic radiation, and a light source indicates a hit when the incident radiation satisfies defined detection criteria. According to the invention, the light source is mounted directly in one or more strips ( 12 ) which in the present case can be the same as the detector strips and consist of distributed light points preferably in the form of light-emitting diodes ( 14 ). In this way, a protected and integrated solution is obtained which has little effect on the shape of the target.
Patent SE-520223-C2 (SE)
Inventor: SIMONSSON RUTGER
IPC: E01H5/02
Filed: 2002-02-06
Abstract: This invention refers to a manual operated snow pusher, consisting of a shovel provided with several wheels and a handle. It earlier exists two types of wheel provided snow shovels. The first type is preventing the leading edge from engaging the surface frictionally. The disadvantage with this type of shovel is that it leaves a layer of snow left on the ground. The second type has the wheels behind the shovel to support the load. This type of shovels requires a fairly flat surface to work properly. This invention solves both those problems. The wheels are mounted with their rolling surface parallel to the shovels slipping surface and in rows that are parallel with the shovel's application direction. This embodiment makes it possible to move the shovel on both dry surfaces as on ice and deep snow. This without leaving a gap of snow left on the cleaned surface.

Title: Cell tissue activating appts. using electrical probe - stimulates cells, tissue areas and organs in living beings
Inventor: NORDENSTROEM BJOERN
IPC: A61N1/20
Filed: 1988-10-27
Abstract: The relative electrical charge of a cell or organ unit can be affected by capacitive connection between the interstitial fluid in an organ area and a differently charged capacitor. An electrode introduced into this fluid and connected to earth, which is a reference for determining the tissue potential activates the relative voltage over the cell membranes and the voltage of the organ in relation to others. This effect occurs slowly with earthing but can be rendered more effective by introduction of a voltage source between earth and the tissue. This can give either a positive or negative voltage in relation to earth. The capacitive charge movement between terminals gives rise to a variation in the conditions for ion pumping over the cell membrances. Thus, it is possible to affect the ion transport by voltage blocking and thus even affect the voltage gradients between the electrode tissue ambience and the voltage in the organ outside the affected tissue.

Filed: 1991-12-04
Abstract: A method and a filter unit for cleaning a liquid which circulates in a closed circuit, such as a central heating circuit, from particulate contaminant material, such as magnetite particles, comprises introducing into the circuit liquid soluble chemicals which are active in suspending and agglomerating the contaminant particles, and filtering the circuit liquid with the aid of a filter cartridge whose smallest filter medium openings are larger than a substantial proportion of the contaminant particles. By limiting the flow rate of the liquid through the filter cartridge to a given maximum filter surface load, corresponding to a value at which at least a 70 % reduction of a standard contaminant consisting of kaolin clay Grade C, EEC International, is obtained across the filter, the filter capacity is utilized to a very high degree and favourable separation or extraction of the contaminants is achieved. The filter unit may include a rate of flow limiting means which functions to set the throughflow to a value which will provide the maximum filter surface load in question essentially independently of the pressure drop across the filter.

Abstract: In a system which is supplied from a direct current source (1, 2), primarily intended for traction purposes, at least two main inverters (3, 4) are connected pair-wise in series with the direct current source and each deliver a three-phase alternating current (5, 6). Two auxiliary inverters (10, 11) are connected in series to the same direct current source to deliver auxiliary power (13). According to the invention, a line (14) is connected between the junction points of the inverter pairs on the direct current side, and the alternating current outputs of the auxiliary inverters are each connected to a respective primary winding on a transformer (12). When one of the main inverters drops out, this enables power to be transferred to remaining main inverters through the medium of the parallel auxiliary inverters and the transformer, so as to provide emergency power. <IMAGE>

The user can readily adjust the position of the arm-rest by gripping the part and swinging it slightly upwards while moving the same to the position desired. When the end of the arm-rest has been moved to the height desired, it is released and swung back and now fixed in position to be subjected to load. Lateral adjustment of the arm-rest is achieved by the frame-part (3) resting on a rotatably adjustable floor plate (16), or being rotatably mounted to a wall structure.
