Abstract: An apparatus for the expansion of tube ends inside of a tube plate by means of a probe insertable in the respective tube ends, the probe forming an annular space with the tube member to be widened by means of two seals spaced from one another, a pump operatively feeding the annular space with a pressure medium for the expansion, and a pressure intensifier for bringing the pressure medium to a required pressure. A medium separator is connected via a back-pressure valve to a secondary-sided space of a primary-sided hydraulic oil driven pressure intensifier. A piston displaceably disposed in the medium separator is biased by a return spring in the medium separator, and the pump feeds the hydraulic oil displacing the piston against the restoring force of the return spring for the filling of the secondary space of the pressure intensifier with an operating medium. The operating medium flows from an operating medium-supply container and another back-pressure valve to the secondary side of the medium separator.

Abstract: A method and apparatus are disclosed for displacing a crane lift hook and hook cable to follow the relative vertical motion between a crane and a loading deck such as occurs between floating vessels and a fixed crane. In the method, the hook cable is paid out or reeled in to maintain the hook a substantially constant distance from the deck in order to facilitate loading or unloading of cargo from the hook. The apparatus for achieving the method includes a vertically displaceable sheave over which the lift cable is reeved, a power ram to displace the sheave, and motive means operating the power ram. Preferably, the power ram is subjected to a constant upward pneumatic force to provide at least a portion of the force for displacing the moveable sheave upwardly to reel in the cable, such as in response to an upward heave of the deck relative to the crane. Variable displacement hydraulic pumps provide an additional hydraulic upward force to the power ram or alternatively provide a downward hydraulic force to displace the ram downwardly against the constant pneumatic force in order to displace the sheave down and pay out the cable, such as when the deck moves away from the crane.

Abstract: The error signal of a primary regulation circuit 10, 18, 20, 22, 24, 30, 32, 42, 44, 46, 50, 28, 52, 16 and 14 is infed as a control signal or magnitude to an air quantity auxiliary regulation circuit 24, 30, 32, 42, 44, 46, 50, 28 and 26. The quantity of supply air which is infed to the room or area which is to be ventilated or climatized, is proportionally influenced as a function of the regulation magnitude of the primary regulation circuit. A lower threshold and an upper threshold are adjusted for the infed quantity of air. In order that the proportional band, related to the room temperature, shall remain independent of at least the adjustment of the upper selected threshold or threshold value, the slope of the regulation characteristic of the proportional band is altered at least during adjustment of the upper threshold. By virtue of such arrangement, computation and post- setting of the proportional band is not altered at least during adjustment of the upper threshold. The primary circuit compares at 10 the actual room temperature, measured at 16, with a desired value set at 11. The auxiliary circuit compares at 24 the actual air flow or velocity, measured at 28, with the temperature error. The only corrector is a flap or valve 48. <IMAGE>
