The invention relates to a hydraulic unit for feeding an object at a desired feed speed a distance in a given feed direction during a working stroke and, in a return stroke, bringing the object back to the initial position at a considerably greater return speed, comprising a double-acting working cylinder (1) with a piston (16), the piston rod (17) of which is connected to the object which is to be moved, and a receiver cylinder (2) which is provided with a second piston (28) and designed to be filled with oil from the working cylinder during the return stroke, the first piston (16) and the second piston (28) being interconnected by a rigid connecting member (31) which forces the second piston to follow the movements of the first piston.

Methods for detecting the condition of a catheter providing access to a patient's blood vessel are disclosed in which the blood is supplied to an extracorporeal blood flow circuit. The method includes generating a pressure wave on one side of one of the access points for supplying blood to the extracorporeal blood flow circuit or returning the blood to the patient, then sensing the pressure wave on the other side of the access points. Apparatus for detecting the condition of the catheter are also provided.

An industrial robot has a position controller for each one of the axes of the robot and a computer for control of the robot. The computer continuously determines, with the aid of a mathematical model set up in advance, in dependence on the robot configuration and load in question, the mass moment of inertia of the axes, the coupled mass moment of inertia, and the moment caused by gravity. From the relationships between acceleration/deceleration and the drive motor torque for the different axes, the maximum available acceleration/deceleration for the axis is determined while assuming that maximum motor torque prevails for each axis. For each axis this value is compared with the maximum acceleration/deceleration value that may be allowed from the point of view of stability. On the basis of the lower of these values, optimum gain is determined and set in the position controller and/or a path planning parameter.
摘要:
A ship hull, especially intended for oil and chemical ships, passenger ships are fishing ships, comprising a hull made of steel or aluminium built on a supporting structure of frames, stringers and longitudinals, having improved buoyancy and energy absorbing capability, and a method of manufacturing such a ship. Between an outer hull (200) and an inner hull (202) a layer (204) of a cellular plastic material is applied having chiefly closed cells. The outer hull is made of a high strength steel, wherein at external strain the outer hull and the cellular plastic material are adapted to jointly constitute an energy absorbing deformation zone.
摘要:
Methods for the central preparation and distribution of a concentrate to a plurality of medical treatment devices are disclosed comprising supplying a stream of substantially only water to a central container which includes a single salt composition at least partially in solid form, producing a substantially saturated solution of the salt composition in the central container, and distributing the salt solution to a distribution conduit which includes a plurality of concentrate connectors whereby the salt solution can be distributed to the plurality of medical treatment devices. Methods for disinfecting this apparatus, the apparatus itself, and containers for use in the apparatus are also disclosed.

摘要:
A method and an apparatus for reducing of and diverting radiation from all kinds of radiation emitting surfaces like viewing screens, TV screens, chassis, apparatus boxes etc. whereby an elecrically conducting current diverting means (11), for instance a coil of stainless steel, is applied in direct contact with the radiation emitting surface (9) and is connected to earth (12), and whereby a fluid layer containing film or foil or a mass is applied directly to the radiation emitting surface (9) and the diverting means (11), said fluid layer or mass comprising a salt of electrolytic type, and in which the mass is of the type which forms a surface skin or becomes dried right through when being exposed to air, and said layer or mass being electrically conducting even in such dried state, and whereby the apparatus is ready for being used when said mass has formed a skin or has become dried. The current diverting means can be applied after the application of the electrolytic layer or mass. The fluid layer or covering mass preferably is a salt of an acid and an alkali metal or calcium, for instance sodium or potassium lauryl ether sulphate or calcium lauryl ether sulphate.
摘要:
A machine for treating or processing, e.g. injection moulding or extruding, plastic material which is available in packaged form said machine comprising, in a manner known per se, an extrusion nozzle (7, 9) and a feed channel (23) connected thereto, is combined with a device (31) for emptying the packages into said feed channel by deformation of the package (71). Before the emptying exit openings may be provided in the packaging material by means of special perforating members (93 to 97). The deformation and the emptying of the package takes place in a cylinder (47) by means of a piston (45) fitting therein and driven by means of pressurized fluid.
