Abstract: A variable speed drive system for prime mover driven accessories which includes a self-energized controllable belt tensioner in combination with a variable diameter pulley assembly. The tensioner, upon command, uses a pump continuously driven by a fixed diameter pulley positioned by a rotary or linear actuator to take up and tension the belt passing over the same pulley. In the variable speed drive, this tensioner functions typically together with a variable diameter pulley which operates on the belt by forces which are directed toward increasing the variable pulley diameter. A hydraulic flow system with appropriate pump, valves, lines, and actuator can all be self-contained in the rotary tensioner. Selenoid valves are used in an on-off fashion with an actuator to move a pulley arm attached to the actuator generating the required belt tension to decrease the variable pulley diameter as desired upon command.

Abstract: Apparatus and methods for improving the ventricular activation sequence of the heart by pacing at an advantageous selected ventricular location to achieve shortening of the QRS complex or pacing at multiple advantageous selected ventricular locations, either simulataneously or with a programmed delay or delays between firings, to achieve shortening of the QRS complex in combination with producing a desirable and efficient ventricular motion. During a cardiac cycle initiated by intrinsic cardiac activity, stimulating impulses may be directed to advantageous selected locations of the ventricles by employing intrinsic cardiac signals to trigger the stimulating impulses, either simultaneously or with a programmed delay or delays between the sensed event or events and firing event or events, to provide improved mechanical and electrical ventricular function.

Abstract: A magnetic pickup tool including a length of highly flexible tubing with a permanent magnet secured to one end of the tubing. Removably positioned within the interior of the flexible tube is a stiffening member such as a length of iron wire of about the same length as the flexible tubing. The stiffening member is bendable but when bent has the ability to take a "set". A second length of flexible tubing completely surrounds the first or inner tubing and is slidable thereon. The function of the outer tube is to surround the magnetic tip when the tool is in the process of being positioned to pick up an object so as to prevent the magnetic tip of the tool from being attracted to an unwanted metal object. After the tool has been positioned at or near the object to be picked up, the user then grasps the outer tube and pulls it away from the magnetic tip exposing the tip to make contact with the desired object. A further feature of the tool is that the stiffening member is removable.
