Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed a method of controlling inter-stand tension in rolling mills in which a tension measuring device is provided on each stand.  The tension measuring device comprises a pair of load sensing devices provided respectively at the entry and delivery sides of the roll stand.  Difference between outputs from the pair of load sensing devices is used as an output value of the tension measuring device.  First, while a workpiece is captured by the second stand but is not yet captured by the third stand and when the tension in the workpiece between the first and second stands is consistent with a desired value, the output value from the tension measuring device of the second stand is stored.  After the workpiece has been captured by the third stand, the difference between the stored output value and the output value from the tension measuring device of the second stand is used as the measured value of tension.  The tension control for the workpiece between the second and third stands is carried out on the basis of the difference between the measured value and a desired value of tension between the second and third stands.

Abstract: ABSTRACT    An improved method of forming articles, such as airfoils, includes forming the major side surfaces of a plurality of airfoils in two groups or series along opposite edge portions of a workpiece by utilizing a plurality of pairs of electrodes to effect the electrolytic removal of material from opposite sides of the workpiece.  Leading and trailing edge portions of the airfoils are formed by utilizing a plurality of relatively long narrow electrodes to effect the electrolytic removal of material to form slots between the major side surfaces of the airfoils and the remaining portion of the workpiece.  During the electrolytic removal of material to form both the major side surfaces and the slots at the leading and trailing edge portions of the airfoils, an electrical potential is establish-ed between the electrodes and the workpiece and a flow of electrolyte is maintained between the electrodes and the work-piece.  After the workpiece has been inspected, a b formed in association with each of the airfoils.  This is accomplished by utilizing a pair of cutting tools to simul-taneously form grooves along opposite sides of the workpiece between the two series of airfoils.  After the grooves have been formed, the two series of airfoils are separated from each other and cutting tools are utilized to complete the formation of the bases in association with the airfoils.  As this is being accomplished, the various airfoils and their associated bases are separated from each other.  The tip end portions of the airfoils are then finished by an electrochemical grinding operation.

Abstract: HYDRAULIC HAND JACK WITH NEEDLE RELEASE VALVE            Abstract of the Disclosure A hydraulic vehicle jack including a novel release valve is disclosed.  The jack is of the type having a high pres-sure cylinder, a ram partially extensible from and retractable into the cylinder, and a high pressure pump for forcing fluid from a reservoir into the cylinder to extend the jack.  When it is desired to lower the jack, the release valve needle is turned so as to withdraw a needle tip from fluid-flow-halting engage-ment with a valve seat.  This needle tip is formed in the shape of a cone having an altitude of a dimension greater than the cone base radius.  When the needle tip is withdrawn from its po-sition against the valve seat, a small but precisely defined fluid-flow-permitting orifice is created.  Valve lowering action then occurs over an extended time period which permits the jack operator to precisely control or halt valve lowering action as desired.

Abstract: ABSTRACT      A disengaging spindle locking mechanism for the latch bolt of a mortise type lock is actuated by the locking slide which is normally employed to engage a retractor hub to prevent the hub from being rotated. At the inner end of a split spindle where it is in non-rotatable engagement with the retractor hub there is a cam surface. On the inner end of a locking slide is a cam surface which cams the spindle out of engagement with the hub as hub action is blocked by the slide. Thereafter, should force be applied to the spindle, it will merely spin in place and no damage will be done to the lock mechanism such as might otherwise be done by unauthorized persons to force open the lock.
