Abstract: A composite material has a laminated structure of fiber-reinforced resin layers and films of a shape-memory alloy. A predetermined strain has been applied to each film. A damage sensor has a film of an alloy of nickel and titanium. An electric circuit is bonded to the film, and strain gages are connected to the electric circuit. The damage sensor can be laminated to the resin layers in place of the film of the shape-memory alloy. Damage to the composite material is suppressed as follows: A current is applied to the films of the shape-memory alloy, to monitor change in electric resistance of the films. The damage is located in response to the change in electric resistance. Another current is applied to a film of the shape-memory alloy for which the change is larger than the other films to generate heat for deforming the film to generate shrinking stress or shear stress to the damage.

The link mechanism has: an axial rod; and two spherical bearings to support the axial rod, the two spherical bearings being capable of changing relative positions, wherein the motion of one of the two spherical bearings relative to the axial rod along the axis is constrained, and the other of the spherical bearings can travel along the axial rod.

Abstract: A chuck (1) for tools, especially screwdriver bits with a polygonal section (2), has a polygonal cavity (3) for the insertion of the polygonal section (2). A wall (4) of the polygonal cavity (3) has a window (5) in which is disposed a pressure-piece (6) which can be displaced in the insertion direction (E) and which, in order to secure the inserted polygonal section (2) against being drawn out, is forced against the polygonal section (2), in a direction transverse to the insertion direction (E), by a sloping inner wall (9) of an actuating element. The actuating element is outside the window and is retained in a clamping position by a restoring spring (10), and, in a release position of the actuating element (7), moves aside out of the polygonal cavity (3) in order for the polygonal section (2) to be drawn out.

During signal transmission, this frequency is altered in a manner which is known only to the control unit and to the radio key.

Abstract: A closing body is mounted in an axially displaceable manner in a bore of a fluidic valve to control a pressure medium flowing via the valve. The closing body has a sealing section, interacting with a seating edge of valve, and a guide section which serves to guide the valve cone in the bore. The guide section is provided with recesses which allow an overflow of pressure medium between the two sides of the closing body. To reduce costs of production, the guide section of the closing body is of cylindrical form and its surface is provided with at least one helical groove which leads from one side of the guide section to its other side. The closing body is useful in particular in constant pressure valves for controlling fluid pressure medium. The sealing section of the closing body is normally of conical form.

Abstract: A hydraulic radial piston engine has a lifting ring fixed to the casting, a rotor mounted opposite the lifting ring such that it is rotatable about an axis of rotation, multiple piston seats aligned radially in the rotor relative to the axis of rotation, and multiple pistons each displaceably mounted in a piston seat and which, over at least part of their length, have a non-circular guiding and sealing cross section that is coincident with a non-circular guiding and sealing cross section of the piston seats. Circularly cylindrical rollers are borne by the piston. With a given overall size, a greater swept volume per piston is possible and therefore a greater torque is produceable.

Abstract: In a display unit for a motor vehicle, a display designed as an LCD is arranged in the same plane as a dial plate of a pointer-type instrument. For this purpose, the dial plate has a cutout into which the display is bonded. This makes the display and the dial plate particularly easy to read.

Abstract: A drive device has a drive element movable axially by means of an electric motor and a hydraulic unit. In the drive device it is important to execute a rapid adjusting movement and then to exert high forces. This causes high reaction forces on the lifting spindle. High reaction forces are avoided if a force intensifier with two pistons movable in relation to one another and differing from one another in the size of their active surfaces along with an intermediate part which, together with the pistons, encloses a pressure space filled with a pressure fluid is used, if the smaller active surface is connected mechanically to the drive element, for the adjusting movement, the hydraulic unit can be moved as a whole, and if, for exerting a high force by means of the larger active surface, the intermediate part can be blocked against displacement in relation to a fixed stand.

Abstract: A drive device for closing unit, injection unit or ejectors of a plastics injection molding machine, has a drive element which is axially moveable, and a hydraulic unit which is moveable by the drive element in the same direction as the drive element. The hydraulic unit is a force multiplier with a large piston and a first small piston, which are moveable in relation to one another and differ in size of their effective surface areas. An intermediate part together with the pistons encloses a pressure chamber filled with a pressure fluid. The first small piston is mechanically connected to the drive element. A second small piston with the intermediate part define a fluid chamber connected by a valve, in one embodiment, to the pressure chamber. The hydraulic unit as a whole is moveable for the positioning movement and the intermediate part is blockable against displacement in relation to a fixed frame.

The circuit arrangement (1) has a particular wide dynamic measurement range.

Abstract: A directional control valve for a hydraulic load has, in a piston bore of a valve housing, a control piston which can be displaced axially in opposite directions from a central position and which has first fine control grooves for opening a connection between a load chamber and a feed chamber. There are second fine control grooves for opening a connection between a load chamber and a discharge chamber of the piston bore under control. In its central position, there is a restricted relief connection from a load chamber to the discharge chamber via the control piston. The restricted relief connection is obtained via a recess in the control piston, independently of the second fine control grooves.

The stationary cover closes an opening cross-section of the emptying nozzle. The handle, upon pressure actuation, pivots about a point which, in relation to the emptying nozzle is located on an opposite side to an actuating-button surface of the handle, and the emptying nozzle pivots away sideways beneath the cover.
