Abstract: An exercise machine or apparatus having a movement arm to be moved upon exertion of a body part against a resistance including a weight that pivots about an axis as the movement arm is moved by the exerciser. To change the resistive force imposed by the weight, the weight is moved relative to its pivotal axis to thereby increase or decrease the effective resistive force. The movement arm is operatively connected to the resistance by a cam connected to the movement arm and engaged with a follower which in turn is connected to the weight to pivot the weight about its pivotal axis. The cam is operatively connected to the movement arm by a strain gauge and a releasable lock mechanism.

Abstract: A welding method that permits thick pieces of metal to be welded together over the entire face of their touching surfaces during a process of self organizing, single pass arc welding in the ambient air without any special proofing of the welding bath melt. The higher quality and faster weld when welding considerably thick metals in a single pass is achieved by using an insulated stationary consumable electrode clamped between the parts to be welded together and by scientifically substantiated selection of the value of the electric power applied to the end face of the electrode.The arc is distinguished by the fact that the value of its power is sustained at a level which keeps the pressure of the metal vapor P.sub.me which arises due to vaporization of the electrode material in the welding zone higher than the air pressure P.sub.atm with a relation between them complying with the rule P.sub.me .gtoreq.(1.1-2.0)P.sub.atm.

Abstract: Method and apparatus for automatically supplying containers with a liquid using an electronic scale and high speed microprocessor for measuring the weight of liquid introduced into the containers. The first container is partially filled to a predetermined percentage of a target weight as measured by the scale. Flow into the container is then stopped by closing a valve controlled through the scale and microprocessor. The actual weight of the liquid introduced at this point is measured and a correction factor is determined by subtracting the predetermined percentage weight from the actual weight. Flow into the container is then resumed until a second predetermined weight is achieved as measured by the scale and equal to the target weight minus the correction factor. Flow at this point is stopped by again closing the valve.

Abstract: Abutment posts, gingival collars, and universal adaptors along with their fixation screws that are used for insertion into dental implants are revealed. The adaptor is universal in that it matches to many different shaped, sized, and styled implants, and standardizes their restoration with uniform gingival collars and abutment posts. A gingival collar of varying sizes, which extends from the top of the flange of the adaptor to the height of the gingival tissue, is used to bring the restoration of the implant into the oral cavity. A post becomes connected to the gingival collar to create a restoration for the placement of a crown or coping over the implant. The top of the adaptor has a projection which is indexed and the top of the gingival collar is also indexed. This indexing allows specific angle correction in the horizontal plane by the counter rotation of the gingival collar and the post head.
