Abstract: A golf pronation and training device comprises a first member adapted for attachment to an upper forearm of a golfer and a second member adapted for attachment to the hand of the golfer. A torsion spring is interconnected between the members for preloading the device with a predetermined magnitude of torquing force when the device is attached to the upper forearm and hand of the golfer. The device functions to rotate the golfer's lower forearm and hand to thereby "release" a golf club immediately following the moment of impact of a club head with a golf ball. In addition, the device induces a "square-to-square" relationship during a golfer's backswing.

Abstract: A monitor system for sensing the failure of a rupture disc and activating an alarm in response to such a failure. The system also senses potential failure of a rupture disc. The system includes a failsafe signal carrying loop which is broken when the rupture disc fails, thereby interrupting the signal. The system also includes a signal sensor which recognizes a signal interruption or substantial modification in the signal and initiates and cooperates with an alarm device to provide notice to an operator or a safety device that the rupture disc has failed.

Abstract: Paper or like media, utilized for maintaining a permanent record of printed matter, is driven by a drive roller and is caused to be wound on a spool or core which is swingable from the drive roller as the amount of paper on the spool increases. An "O" ring drive is positioned between a main drive line for intermittent engagement therewith and is connected with the spool for driving thereof.

Abstract: A single clutch and associated actuator mechanisms in a drive line for providing selective driving or feeding of at least two printing media for independent bi-directional movement of the media in the operation of a plurality of printing functions. The drive or feed mechanism for the printing media occupies the space of a single printing station wherein drive members are arranged in an overlapping manner with individual control of such drive members.
