    Abstract: A hydraulic pump assembly (10) for powering a hydraulic torque wrench (24) i s air-powered and has hydro-pneumatic control circuitry (39) which continues operation of an air motor (18) which drives t he hydraulic pump (16) for a post-advance period after an advance actuator (55) is deactuated. Operation of the pump (16) is continued for a period sufficient to retract a double-acting torque wrench (24), to permit subsequent advances of the wrench (24) within the post-advan ce period without restarting the pump (16) or to permit a single acting wrench to be moved from one fastener to the next within the po st- advance period without restarting the pump (16). Operation of the pump (16) is terminated when the post-advance period expires if the advance actuator (55) is not reactuated, so as to conserve energy and avoid unnecessary heating of the hydraulic fluid.

    Abstract: An apparatus for counteracting vibrations includes a housing for attachment to a vibrating member. First and second bodies are connected to the housing by first and second springs, respectively, with a combined stiffness which defines a resonant frequency at which the first and second bodies oscillate with respect to the housing. Each of the first and second springs include a plurality of rods fixedly connected between a pair of rings. A lever engages the first and second bodies to vary a spacing between those bodies when force from an actuator is applied to the lever. The lever action alters the stiffness of the first and second springs which varies the resonant frequency of the vibration absorber.

    Abstract: An operating mechanism for use in a vehicle having a bedroom slide out, the bedroom slide out having a platform which is movable laterally relative to a vehicle having a stationary floor. The operating mechanism laterally moves the movable room section relative to the stationary room section between a retracted position and an extended position, and has a height adjustable frame. The frame includes overlapping side members which are slidably moveable relative to each other and fastenable at two or more discrete heights.

    Abstract: A hydraulic actuating device has a drive actuator (1) and a latch actuator (30) for latching the drive actuator or an object which is coupled thereto, in particular a tiltable vehicle cab. The latch actuator has a housing with a cylinder space, inside which a piston (36) can move. The housing is provided with a first connection (50) and a second connection (51), which are in communication with a first port (54) and a second port (55). Furthermore, a third port (56) and a fourth port (57) are connected to the cylinder space and are each in communication, depending on the position of the piston, with the first chamber (37) or the second chamber (38). The third port is in communication with the first connection and the fourth port is in communication with the second connection. A nonreturn valve (60) which closes in the direction of the third port is provided between the third port and the first connection. A nonreturn valve (61) which closes in the direction of the fourth port is provided between the fourth port and the second connection.

    Abstract: The actuator has an extruded tubular body. The tube has a sliding guide sector (14) extending in the longitudinal direction. The locking device (16, 17) is in the form of a slide which can be moved along the guide sector between a position for the insertion or removal of the fluid line fitting (12, 13) and a position in which the fitting is locked in place.
