摘要:
A transom plate for small fishing boats which simultaneously adjusts vertical displacement and trim of the outboard motor. The transom plate is adapted particularly for smaller fishing boats which must operate under widely varying loads and speeds, and which often encounter extremely shallow water. The plate comprises a rigid transom frame adapted to be clamped to the transom, and a motor bracket slidably movably coupled to the frame. Movement of the motor bracket relative to the transom frame is facilitated by a power cylinder preferably controlled from within the boat. The cylinder is pivotally coupled between the transom frame and the motor bracket, being secured and centered by L-brackets. Special follower slots are defined through each side of the jack to define a path of movement for displacement of the motor bracket relative to the transom frame. A generally vertically oriented slot is paired with a generally inclined follower slot on each side of the plate. Vertical displacement of the motor bracket results in simultaneous trimming of the motor.

A laser aiming device having a plasma tube encased by a cylindrical member upon which windage and elevation adjustments act. Resilient ring members separate the cylindrical member from the plasma tube. Another resilient member located between the cylindrical member and an outer housing member cavity wall provides counterforces against which the windage and elevation adjustments act.

Provided herein are small diameter inlays for correcting vision impairments by altering the shape of the anterior corneal surface. In an embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an “effective” zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the “effect” zone. In another embodiment, small diameter inlays are provided that induce effective optical zones on the anterior corneal surface that are much larger in diameter than the inlays. The increase in the effective optical zone, due at least in part to a draping effect, allows an inlay to produce a much larger clinical effect on a patient's vision than the diameter of the inlay.

A method is presented that enhances the survivability of system software components, even in the event of catastrophic failure of the computing element on which they reside. In particular, the combination of a distributed operating system (Non Stop Clusters) and a fault-tolerant interconnect (ServerNet) provides an environment conducive to posthumous recovery strategies that have been unavailable in previous distributed computing environments. The specific strategy outlined here is called resource harvesting, and involves a novel approach that retrieve critical data structures of memory from a failed computing element for reconstruction on a non-failed computing element, allowing such critical data structures to continue with their original function.

A system area network computer system architecture is structured as a single system image cluster operating system to offer an opportunity to increase the availability to I/O devices in the system. The computing system comprises a number of processor units coupled to a plurality of input/output (I/O) elements by a routing fabric that provides each of the processor elements with access to any one of the I/O elements. Using a Transparent Network Computing extension to a highly available version of UNIX System V Release 4.2, the system provides a higher degree of availability to I/O devices by providing for the takeover of their controlling entity.

摘要:
An improvement for grand piano actions reduces unwanted friction between the repetition lever and the hammer shank. The conventional grand piano knuckle is replaced by a lever disposed generally parallel to the repetition lever and pivotally secured thereto at one end. An adjustable spring provides a force biasing the lever away from the repetition lever. A travel limit adjusts the maximum pivotal excursion of the lever relative to the repetition lever. At the opposite end of the lever, a centrally pivoted platform structure is pivotally secured. The structure includes a surface which engages the hammer shank and at least one brake surface which engages the repetition lever.
