摘要:
A hydraulic cylinder that locks into position has a housing (1) with at least one pressure connection (7) and a piston (3) and rod (6) that travel tight in an out of the housing. The locking mechanism comprises a piston (11) that rests against a spring (35) and a barrier mechanism (23) with a cage of balls (25) that roll radially into a locking position in a locking groove (26) and back into an unlocking position in an unlocking groove (22). The primary piston communicates with a hollow space (18) and acts on a primary participating surface (19) and the locking piston communicates with an unlocking space (13) and acts on an unlocking surface (14) by way of the pressure connection. There is a variable choke (17), which disengages after a while, beween the pressure connection and the primary space (18) in the primary piston (3). The unlocking space in the locking piston (11) can be supplied with fluid without being choked by way of the pressure connection, so that, once fluid has been supplied from the pressure connection, no pressure can build up in the primary space until the locking piston has left its locking position.

摘要:
A force transmitting connection element having an insulation body limited by two oppositely located support surfaces which are at a distance corresponding to a height H of the force transmitting connection. A first support surface faces a first cast structural component part and has a length L1 and a width B1. A second support surface limiting the insulation body faces a second cast structural component part and has a length L2 and a width B2. A longitudinal center axis runs through a center of the insulation body. A element penetrates the insulation body. An element for transmitting transverse force projects beyond the compressive force transmitting connection element in direction of the first cast structural component part and a ratio between transmissible compressive force and transmissible transverse force is between 1.5:1 and 15:1 and a distance LK is less than (B1+B2)/6.
摘要:
A method and apparatus for charging a rechargeable battery with a current from a controllable current source. In order to adjust the rated current of the controllable current source, at least one operating parameter of the rechargeable battery, such as the rechargeable battery voltage which is produced as a consequence of a charging process, is detected. A pulsed control signal with a duty ratio which corresponds to the desired rated current is produced as a function of the operating parameter. The duty ratio of the pulsed control signal is evaluated, and the rated current of the current source is adjusted as a function of the duty ratio of the pulsed control signal.
摘要:
The invention relates to a method for renewed activation of honeycomb-shaped catalyst elements for denitrating flue gases from fossil fuel-fired boiler plants, specially coal-fired boiler plants in large power stations. According to the invention, each catalyst element if mechanically cleaned using oil and water-free compressed air before mounting. Subsequently, each element is subjected to wet chemical cleaning using fully desalinated water and dried with oil and water-free compressed air. The inventive method enables the activity of used catalyst elements to be increased from less than 50% to more than 83% of original activity.
