When the shock absorber is mounted on a chassis member, the retainer is depressed downwardly against the biasing force of the spring and the rod is inserted into a bore formed on a chassis member through a opening side groove thereon. After that, the retainer is held in a recess on the bottom of the chassis member so that the rod is reciprocable along the retainer and the bore of the chassis member to absorb the vibration or shock from the wheel.

Abstract: A rotor of a salient-pole type rotary machine is disclosed in which field coils are held by a coil brace disposed between adjacent magnetic poles. In addition to the coil brace, a holder provided with an elastic member is also disposed between the magnetic poles, and another elastic member is disposed between the coil brace and the said holder, whereby the said two elastic members are utilized for the fixing of the field coils and for the pressing force of the coil brace. And the whole of the coil holding mechanism is separated from a spider. This construction permits the field coils to be held in place without any great change in the holding force under any dimensional change.

Abstract: This invention relates to an insert freely displaceable in a coil spring that at opposite ends abut against spring support formed in a motor compressor unit capsule and a spring support formed by a stator plate. The spring supports project into the opposite ends of the spring to extend toward one another.

The insert serves as a transport abutment and permits lateral movement without excessively deforming of the spring.

Abstract: The device comprises two rods which are each intended to be connected to one of the structural elements, and at least one helical spring whose ends are connected to two discs, each associated with one of the rods, so as to oppose the movement apart of the rods through the discs. The latter are mounted for axial sliding relative to the associated discs and are formed in such a way that their movement both towards and away from each other causes tensioning of the spring from its undeformed rest condition. The device acts as a rigid connecting element when thestresses applied to it are less than a predetermined threshold. When the stress exceeds the threshold, however, it deforms resiliently to limit the amount of stress transmitted to the members between which it is connected.

In order to prevent this spring from extending beyond a predetermined length corresponding to a predetermined design load, the apparatus includes a lanyard having a flexible lower portion with a loop at the lower end and a rigid upper portion threaded at its upper end. At loads above the design load a self-locking nut threaded on the upper end of the lanyard abuts a horizontal surface of the traversing member and the loop at the lanyard's lower end engages a horizontal pin mounted on the lifting pad, whereby the portion of the load in excess of the design load is borne by the lanyard and further extension of the spring is prevented.

The spring is coaxially disposed in the assembly between the inner surface of the housing and the outer surface of a sleeve member inserted within the spring, thereby retaining the spring in a symmetrically coiled state, that is, preventing radial distortion or buckling of the spring spring when subjected to operating stress. The entire spring assembly is retained in its assembled state by radially crimping the opposite ends of the housing against the outer radial surfaces of the retaining washers. The overtravel spring assembly is used in an automatic slack adjuster for vehicle brakes for measuring the extent of overtravel of the piston rod due to excessive wear of the brake shoes.

Abstract: A top nozzle for a nuclear reactor fuel assembly which includes an orifice plate designed to receive control rod guide tubes extending upwardly from the top of the fuel assembly. Nozzle pin extensions connected to the orifice plate are axially coextensive with the guide tubes and project upwardly through a top nozzle hold-down plate, and through openings in the upper core plate in the reactor. The hold-down plate is spring biased into an upper core plate engaging position and since the pin extensions are adapted to move in the core plate and against the action of the springs, the top nozzle thus becomes effective in accommodating upwardly acting hydraulic forces which tend to lift the fuel assembly, and to accommodate differential expansion of parts in the fuel assembly as compared to the core barrel in which the assembly is located.

In another embodiment, the ends of the rod or tube move outwardly and engage end pieces which in turn move outwardly and urge cylindrical saw-tooth end caps into contact with the inner faces of the walls of the form.
