Abstract: A cam actuated continuous simultaneously variable valve timing and lifting assembly for selectively operating the valve of an internal combustion engine. The valve is actuated by a cam on a camshaft driven by a crankshaft. The cam is in operative engagement with a slider. The slider is selectively movable by a slider actuator within a rocker arm. The slider actuator is selectively extended and retracted by a first motor drive unit. A computer controller operatively controls the motor drive unit to selectively and simultaneously vary the timing and lifting of the valve. A modification of the invention is provided with a second motor drive unit provided with a downwardly extending hexagonal transfer shaft drive assembly having a downwardly extending spherical ball which operatively engages a rocker arm assembly provided with a slider thereon to accommodate the movement of the slider as needed. Another modification of the invention is provided wherein the second motor drive unit is provided with a downwardly extending selectively rotatable screw type rotary driving gear in selective operating engagement with the rotary driven gear which engages the rocker arm to operate the slider as needed.

Abstract: A variable valve timing and lift assembly for operating a valve of an internal combustion engine. The valve is actuated by a cam on a camshaft driven by a crankshaft. The cam is in operative engagement with a slider. The slider is selectively movable by a slider actuator within a rocker arm slider opening of a rocker arm. The slider actuator is selectively extended and retracted by a motor drive unit. A computer controller operatively controls the motor drive unit to vary the timing and lift of the valve.

Abstract: A storage system useful for storing cryogenic liquids is disclosed. The storage system includes a storage vessel, insulation surrounding the storage vessel and a flexible vacuum jacket enclosing them both. The flexible vacuum jacket can be made from a flexible plastic film such as polyimide. Polyimide is preferred due to its ability to remain flexible at cryogenic temperatures. The inner volume of the flexible vacuum jacket is placed under vacuum such that the insulation is maintained under vacuum. The flexible vacuum jacket can collapse against and conform to the insulation when it is evacuated, saving substantially on volume. A fitting for combining multiple passageways is also disclosed, so that multiple passageways can proceed through the vacuum jacket through a single penetration.

Abstract: A method of forming a friction pad utilizing two distinct compounds. One of the compounds has a high fiber content and the other has a high flow characteristic. The compounds are placed in respective layers in a mold and are compressed to form a composite piece which is placed in a second mold cavity along with a perforated metal plate. Heat and pressure are then applied to the composite piece in the second mold cavity to cause the high flow characteristic compound to flow and enclose the metal plate such that the two compounds and the metal plate are firmly bonded into an integral friction pad.

Abstract: A method and a system for frequency measuring or monitoring and particularly suitable for power system frequencies in the range of approximately 0-2 KHz is disclosed. The technique is suitable for single-phase or three-phase periodic signals. Synchronism of sampling to power systems waveform and zero crossing detection are not required. The method is particularly attractive when used in conjunction with other on-line digital processing/control tasks since the interface between the power network and the computer may be shared and the fast and accurate detection of frequency variation can be beneficially used by the rapid digital processors.
