Abstract: ABSTRACT OF DISCLOSURE            Disclosed herein is a method of and apparatus for forming a cutting link  including a link portion, a shank portion extending from the link portion in angular relation thereto, and a toe portion extending from the shank portion in angular relation thereto and in transverse relation to the link portion, from a saw chain cutting link blank including a link part which provides the link portion, a second part which extends from the link part and which is formed to provide the shank portion, and a third part which extends from the second part and which is formed to provide the toe portion.          The method comprises the steps of placing the blank in an apparatus or die including a stationary die part and first and second movable die parts, forming the shank portion from the second part of the blank and partially forming the toe portion from the third part of the blank by bending the second part of the blank into the shank portion and the third part of the blank into a position extending in generally parallel and offset relation to the link portion in response to movement of the first movable die part in one direction relative to the stationary die part, completing the forming the third part of the blank into the toe portion by engaging and cold flowing the extending third part of the blank into the toe portion in response to movement of the second die part in a direction transverse to the one direction and relative to the stationary die part, and removing the formed link from the die.     ABSTRACT OF DISCLOSURE continued The apparatus comprises a stationary die part, means including a first die part movable relative to the stationary part in a first path and operable, in response to movement of the first movable die part relative to the stationary die part, to bend the shank part relative to the link part to form the shank portion into the angular relation and to partially bend the toe part relative to the shank part, and means including a second die part movable in a direction transverse to the first path and relative to the stationary die part and operable, in response to movement of the second die part relative to the stationary die part, to cold flow the toe part to form the toe portion into the angular relation to the shank portion and into the transverse relation to the link portion.

Abstract: Abstract of the Disclosure An agricultural implement is disclosed, of the kind which comprises at least one working member arranged to be driven at different speeds by way of a gear wheel transmission.  In order to permit of bringing the driving speed of the working member(s) to a value suitable for different operative conditions, such as the kind of soil, the nature of the crop, the working rate or the substances to be spread, this driving speed should be variable in a simple manner without loss of time and, for example, without the need for replacing gear wheels.  According to one aspect of the invention, there is provided an agricultural implement of the kind set forth, wherein a shaft is displaceable in at least one gear wheel in order to be able to select a chosen one of at least two transmission ratios to said working member.  In this way not only the speed of the working member can be readily changed, but also the number of mechanical components involved in setting different opera-tive output speeds is minimized.

Abstract: TRACTION DEVICE FOR USE  WITH A THOMAS SPLINT                    ABSTRACT           This invention relates to a traction device adapted to be slipped onto a lower-leg end of a Thomas splint and including resilient walls to provide a sufficient friction fit with said splint that the traction device will not fall off of the splint by its own weight but which may be readily manually removed from the splint.  The traction device includes a socket which receives the splint and has two cylindrical housings molded integrally with the socket.  The cylindrical housings form bearings and a shaft extends between the housings and receives a belt which is coiled upon the shaft when the shaft is rotated in one direction and uncoiled when the shaft is rotated in the other direction.          The shaft is movable along its longitudinal axis.  It is biased in one direction by a spring, in one of the housings, into a first operating position.  In that position, a set of teeth on the inner end wall of the other housing engages a similar set of teeth on the inner end wall of a knob connected to the shaft, the teeth coacting to allow the shaft to rotate in only one direction to coil the belt upon the shaft.  In a second operating position, which is attained by pulling the knob outwardly against the force of the spring, the shaft may rotate in either direction.

The apparatus comprises an inner longitudinally extending body with an outer longitudinally extending body being around the inner body.          Connection means on one of said inner and outer bodies are pro-vided for connection of a liner extending below the apparatus.          Expander means are carried on one of the inner and outer bodies, with gripping means being carried on the other of the inner and outer bodies.  The gripping means are engagable with the expander means such that the gripping means are shifted into gripping engage-ment with the casing.  A manipulatable tubular running tool is releasably secured to the inner and outer bodies.  Drag means are mounted on the running tool and are slidable longitudinally along the casing, the drag means resisting longitudinal travel of the apparatus while in the well bore with sufficient frictional force to support the weight of one of the inner and outer bodies there-below.  Disengaging means are provided for selective disengagement of the running tool from the inner and outer bodies.  Setting means are carried on the running tool and are operably associated with the drag means, the setting means being responsive to manipulation of the running tool to longitudinally shift one of the inner and outer bodies with respect to the other of the inner and outer bodies to anchor the liner to the casing.  Wiper means selectively dis-engagable from the running tool are provided together with means for disengagement of the wiper means from the running tool.  Side seal means are carried on the running tool to detect disengagement of the running tool from the inner and outer bodies.

Abstract: ABSTRACT OF THE DISCLOSURE        In sheet-rolling mills where the rolls are normally under maximum rolling pressure, the mill is said to be "pre-stressed."  Load transfer blocks exert a force to relieve a part of the pre-stress for each particular strip rolling operation.  This invention has a combination of hydraulic pressure and gas pressure for providing a controlled sub-stantially unyielding  force   during a rolling operation, and a yielding shock absorber for preventing full pre-stress load from coming on the rolls when an end of the strip passes the rolls or when a strip breaks.
