    Abstract: A gravity compensation apparatus is provided, including a force output device, an axis and an arm with the axis as rotational center. The present invention is to output a force via the force output device to the arm when the arm contacts the force output device. When the arm rotates in the first or second quadrants, the contact point between the arm and the force output device will change continuously so that the force rotation speed of the force output device, the effective length of the lever arm and the force-applying angle will also change accordingly. Through appropriate design, the generated torque value can show a non-linearly increasing curve approximately to a sin function between 0-90°.

    Abstract: In a pipe support of the constant tension kind, spring means, which through a connecting link acts on a lever pivoted to a carrier, is adjustable relative to the carrier for altering the moment of the spring force about the pivot of the lever by varying the perpendicular distance from the pivotal axis to the central longitudinal axis of the connecting link. Slots in the carrier are engaged by screws which tighten into an end wall of a housing of the spring means to secure the spring means in adjusted positions. By the adjustment the moment of the spring force can be boosted, changes in the load moment of a supported pipe, e.g. as a result of pipe ratchet, can be readily compensated for, as also can deviations of the rating of the spring means from a mean manufacturing specification.

  • Patent number: 4206898
    Abstract: A spring support of the constant spring force type suitable for supporting pipes in installations where the pipes are liable to move laterally while in use, as for example in the case of pipes through which steam is conveyed, is arranged so that the pipe or other load which the support has to carry in use can be attached to a pivoted lever of the support at various positions at different distances from the pivot. The load is attached through load connecting means to a carrier which is variably positioned on the lever. By adjusting the position of the carrier the turning moment produced on the lever by any one of a range of loads can be arranged to be equal and opposite to the turning moment produced by the spring force which acts on the lever. The facility for adjustment has the manufacturing advantage that a standard form of lever can be produced for supporting a range of loads.

  • Patent number: 4163041
    Abstract: A support arrangement is used for elastically mounting a monolithic ceramic honeycomb structure within a housing in an exhaust gas pipe and consists of a holding angle and a molded part formed of a soft, flexible material. The holding angle is rigidly secured to the inner surface of the housing with one of its legs extending along the wall of the housing and the other extending radially inwardly from the inner housing surface. The molded part is rigidly secured to the inner end of the other leg of the holding angle and extends from its point of rigid securement in generally the same direction as but spaced inwardly from the one leg of the holding angle. At its end opposite the end secured to the holding angle, the molded part is bent radially outwardly into sliding contact with the inwardly facing surface of the holding angle. The combination of the holding angle and molded part form a cavity which may be filled with a heat-resistant material.
