Abstract: A high performance, laminating, coverlay, and bond ply adhesive material includes one or more epoxy components which inter-react with a high molecular weight polyester component through a two-stage reaction sequence. The first stage of the reaction sequence includes a reaction between a aziridine cure component and a polyester component. The second stage of the sequence involves a reaction between the aziridine/polyester component and the epoxy component(s). The resulting adhesive material provides a flexible, fully cross linked adhesive material with good Z-axis stability and without the evolution of volatile by-products. This resulting adhesive material can be used in bonding polyimide films to etched circuit patterns to provide a high temperature resistant, solvent resistant, moisture resistant, insulating material with good flow properties under normal electronic circuit processing and environmental conditions.

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: An oxygen permeable bifocal contact lens with a Dk of at least 10.times.10.sup.-11 in which a distance vision portion having a refractive index of not more than 1.49 is formed as a preform in which there is provided a recess, and a near distance vision portion having a refractive index of at least 1.540 is formed by filling the recess with a monomer mixture and polymerizing. It is preferred that the distance vision portion be formed as an interpenetrating network copolymer by partially polymerizing one monomer mixture to a predetermined relative viscosity and then adding a second monomer mixture and copolymerizing the resulting mixture. The near distance vision portion may also be formed as an interpenetrating network in the same manner.

The inspection may also be accomplished by emplacing an opaque pipe provided with spaced part visually clear windows into the subsurface, and thereafter introducing visual inspection means into the pipe to inspect subsurface environments through the windows of the pipe. The invention additionally includes improved piping or casing which is constructed of typical opaque materials such as steel, but which is provided with visually clear windows appropriately spaced throughout the casing.

Abstract: Injection molding methods and apparatus for the production of casting molds for toric lenses having ballast oriented properly with respect to the cylinder axis of the toric surfaces. A calibrated rotatable ring mechanism is used within the injection molding body, for producing a slot or other alignment means on the lens casting mold at a point which is offset a predetermined number of degrees from the axis of the toric surfaces being formed in the casting mold. When the casting mold containing a newly cast lens is mounted on a precision lathe, the mating of the slot with a permanent ridge on the lathe spud ensures that the mold seats on the lathe at the same established place each time with respect to the position of the cutting tool. The offset between the toric axis and the position of the cutting tool has already been established, and therefore there is no need for the lathe operator to make any measurements or resetting of the cutting tool.
