Abstract: The invention relates to an impulse generator for a rock breaking tool, the impulse generator (2) comprising a main chamber (4) for receiving a first pressurizeable fluid volume (6), an in the main chamber (4) received impulse piston (8) which is arranged for transfer of pressure energy in the fluid volume (6) into impulses in the tool (10), and a on the side opposite the main chamber (4) side of the impulse piston (8) situated prepressurizing chamber (12) for receiving a second pressurizeable fluid volume (14), where the impulse generator (2) further comprises a on the side opposite the main chamber (4) side of the impulse piston (8) situated pressure relief chamber (16) for receiving a third pressurizeable fluid volume (18), where the relationship between the pressurizing pressures in the fluid volumes (6,14,18) and the relations between the areas of the impulse piston (8) facing the chambers (4,12,16) are such that pressurizing of at least the prepressurizing chamber (12) displaces the impulse piston (8) in the direction towards the main chamber (4) and the pressure in the main chamber (4) effects a pressure increase in the pressure relief chamber (16) when the prepressurizing chamber (12) is depressurized, whereby the depressurizing rate in the pressure relief chamber (16) and the velocity of the then transferred pressure impulse into the tool (10) are increased (12). The invention also relates to a hydraulic tool comprising an impulse generator (2), and a method for generation of impulses in a rock breaking tool.

Abstract: Road-working cutters are made of a steel containing 0.2- 0.4% of carbon, 1.0-2.0% of silicon, 0.8-2.0% of manganese and 0.5-1.5% of chromium, the rest being composed of iron and impurities. The cutters obtained from this steel have a good notch-bar impact strength, combined with a good tempering resistance. Due to this last quality, the resistance to wear is not greatly reduced by local hot spots formed in the cutting edge due to friction when used on a hard road surface. The cutters can be hardened by quenching in oil, which produces a fine-grained structure of so-called rib martensite when the cutters have a thickness of 9-14 mm.

Abstract: The aerodynamic body 1 may be a missile or a projectile fired at a target 2. By means of the output signal from a homing device 10 fixed at the body, which is a measure of the momentary value of the angle ν between an axis 4 of the body, preferably the axis of symmetry of the body 1, and the desired line 5 between the body 1 and the target 2, the body 1 is steered in a ballistic trajectory with known velocity variations VR over time towards a forward point 8. In the latter, the body 1 and the target 2 are expected to be situated simultaneously at the moment of hit. According to the invention, is subsequent to the firing determined: A first signal value corresponding to the momentary distance r(t) between the body 1 and the target 2; A second signal value corresponding to the time derivative σ' of the angle σ between an inertial reference direction and the desired line 5 between the body and the target; A third signal value Δχ, providing an estimate of the angle between the actual direction of travel 3 of the body and the desired line 7 from the body 1 to the forward point 8. This estimate is obtained as the product of the first and the second signal values, divided by the velocity VR of the body. Finally, the third signal value is compared with a predetermined signal value corresponding to an actuatable change of the direction of velocity of the body with a certain angle Δχ0. Each time the magnitude of the third signal value Δχ exceeds the predetermined signal value, the change of direction of travel 3 of the body is effected. Hereby, the device becomes appreciably simpler and cheaper. <IMAGE>

Abstract: The gatherable lamellar blind has two lamella-support cables (1, 2). The end rail (4) is connected to the lamella (6). Both are guided in lateral guide grooves (9). The flanged edges (11, 12) are connected to the wire cables (1, 2). In the central part, the lamella (6) is provided with a lamella hinge clamp. Two tabs (20) serve to receive a hinge connection element (21). Two pivot bearing projections projecting on the element (21) engage in the opening of the tabs (20). A cross-sectionally hook-shaped end rail holder (22) holds the element (21) securely. As a result, a connection which is pivotable about two axes (24, 25) is produced between the lamella (6) and the end rail (4). In the closed state of the gatherable lamellar blind, the lamella (6) bears with its rubber piping (29) as extensively as possible against an end rail stop (27). By pulling upwards on the lamella support cable (1), a closing moment is created on the lowest lamella (6), which is not hindered by the hinge connection element (21). The lamella (6) can thus be drawn into a real closing position. It is not possible from outside, by pressure on the upper part of the lowest lamella (6), to cause the latter to pivot out. As a result, a complicated construction and the openability of the lowest lamella (6) from the outside are avoided. <IMAGE>
