Abstract: An actuator, comprising an actuation member positionable into a first retracted position and a second extended position, and a retaining member structured to maintain the actuation member in the first retracted position, and to selectively release the actuation member from the first retracted position in response to an extension force.

Abstract: An interrocker assembly for a transmission includes at least two shift forks for actuating gears in the transmission, each of the at least two shift forks being pivotal and having an end offset relative to each other, at least two actuators cooperating with the at least two shift forks, one of the at least two actuators cooperating with one of the at least two shift forks, and an interrocker being pivotally movable and cooperating with each of the at least two shift forks to securely prevent two gears from being engaged at the same time.

Abstract: A system for ensuring correct insertion and spatial orientation of a prosthesis cup and/or a prosthesis neck of an artificial hip joint is described. The system comprises a tool (30) for controlling the mutual positioning of the main components in a femoral prosthesis; a measuring device (40) for measuring the distance between two supports (2, 2?) connected to the patient s pelvis and femur; and a positioning tool (1) designed to be releasably connected to a handle part (14) connected to the tool according to item a) and to the two supports connected to the patients pelvis and femur. A measuring device and a positioning tool included in the system is also described in addition to a method for surgery by means of the present tools.

Abstract: A system and a method for ensuring correct insertion of the components of a femoral prosthesis, i.e. a prosthesis stem with a ball head and a cup with recess for receipt of the ball head, is described. The system comprises a tool for controlling the mutual angle between the prosthesis stem and the cup in addition to a positioning system for definition of a reference system and for determination and adjustment of the offset and length of the leg.

Abstract: Apparatus for applying pressure in a controlled manner to a moving web of material for the purpose of transferring heat to the web passing over heating means, for curing the adhesive thus bonding together the component sheets making up the web, includes a plurality of pressure rolls resting directly or indirectly on the web, manual and automatic adjustments for varying the effective weight of the rolls to vary said applied pressure in accord with variations in the speed of the web, such being adjustable for varying the rate of said adjustment, and an arrangement for preselecting a condition such that at zero web speed, the effective weight has an initial positive or negative value.
