Phase-angle controller for Stirling engines

An actuator includes a restraint link adapted to be connected with a pivotal carrier arm for a force transfer gear interposed between the crankshaft for an expander portion of a Stirling engine and a crankshaft for the displacer portion of the engine. The restraint link is releasably trapped hydraulic fluid for selectively establishing a phase angle relationship between the crankshaft. A second embodiment incorporates a hydraulic coupler for use in varying the phase angle of gear-coupled crank fpr a Stirling engine whereby phase angle changes are obtainable

The FIRE Project

The International Satellite Cloud Climatology Project's (ISCCP) First ISCCP Regional Experiment (FIRE) project is a program to validate the cloud parameters derived by the ISCCP. The 4- to 5-year program will concentrate on clouds in the continental United States, particularly cirrus and marine stratocumulus clouds. As part of the validation process, FIRE will acquire satellite, aircraft, balloon, and surface data. These data (except for the satellite data) will be amalgamated into one common data set. Plans are to generate a standardized format structure for use in the PCDS. Data collection will begin in April 1986, but will not be available to the general scientific community until 1987 or 1988. Additional pertinent data sets already reside in the PCDS. Other qualifications of the PCDS for use in this validation program were enumerated

Hot gas engine with dual crankshafts

A hot gas engine, such as a Stirling engine is described which comprises a displacer portion and an expander portion with a heat exchanger connected between them. The expander portion has a piston which is operatively connected to and rotates an expander crankshaft. In like manner, the displacer portion is provided with a piston which is also operatively connected to and rotates with a separate displacer crankshafts. The two crankshafts are synchronized with respect to each other preferably by means of an idler gear. Banks of displacer pistons can also be provided for operation on a common displacer crankshaft and banks of cooperating expander pistons also can be provided for operation on a common expander crankshaft

Solar energy modulator

A module is described with a receiver having a solar energy acceptance opening and supported by a mounting ring along the optic axis of a parabolic mirror in coaxial alignment for receiving solar energy from the mirror, and a solar flux modulator plate for varying the quantity of solar energy flux received by the acceptance opening of the module. The modulator plate is characterized by an annular, plate-like body, the internal diameter of which is equal to or slightly greater than the diameter of the solar energy acceptance opening of the receiver. Slave cylinders are connected to the modulator plate for supporting the plate for axial displacement along the axis of the mirror, therby shading the opening with respect to solar energy flux reflected from the surface of the mirror to the solar energy acceptance opening

Squib-operated disconnect

Disconnect device is described, which consists of stud with enlarged end held in collet locked by pins, which are held in place by piston. When squib is fired, trapped combustion products force piston to release pins

Zero torque gear head wrench

A gear head wrench particularly suited for use in applying torque to bolts without transferring torsional stress to bolt-receiving structures is introduced. The wrench is characterized by a coupling including a socket, for connecting a bolt head with a torque multiplying gear train, provided within a housing having an annulus concentrically related to the socket and adapted to be coupled with a spacer interposed between the bolt head and the juxtaposed surface of the bolt-receiving structure for applying a balancing counter-torque to the spacer as torque is applied to the bolt head whereby the bolt-receiving structure is substantially isolated from torsional stress. As a result of the foregoing, the operator of the wrench is substantially isolated from any forces which may be imposed

Disconnect unit

A squib-actuated disconnect is characterized by an expandable collet axially extended from a first tension member for receiving in locking engagement a protuberance axially extended from a second tension member. A gas-driven retainer of an annular configuration is also locked in for supporting the collet in locking engagement with the protuberance. The protuberance is axially displaced in response to a firing of an associated squib for thus accommodating a disengagement of the protuberance and the collet

Bolt installation tool for tightening large nuts and bolts

Large bolts and nuts are accurately tightened to structures without damaging torque stresses. There are two models of bolt installation tool. One is rigidly mounted and one is hand held. Each model includes torque-multiplier unit

The Rights of Man in the World Community: Constitutional Illusions Versus Rational Action

It is only from a perspective of centuries that the United Nations program for human rights can be accurately observed or rationally appraised. This program, too often thought to be at the periphery of the purposes of the United Nations, represents in fact the main core of rational objectives not only of the United Nations but of all democratic government. It represents the converging and integration on a global scale of many movements, movements hitherto restricted in areal diffusion but centuries-old and rooted deep in universal human nature and civilized culture. It is heir to all the great historic democratic movements—for constitutionalism, freedom, equality, fraternity, humanitarianism, liberalism, enlightenment, peace, opportunity, and so on It is the contemporary culmination of man\u27s long struggle for all his basic human values: for participation in the processes by which he is governed, equality before the law, and that wide sharing of power, both formal and real, which we call democracy; for sanctity of person, for freedom from arbitrary restraints and cruel and inhuman punishments, and for positive opportunity to develop latent talents for the enrichment and well-being of personality; for the enlightenment by which rational decisions can be made and for freedom of inquiry and opinion; for that fundamental respect for human dignity which both precludes discrimination based on race, sex, color, religion, political opinion, or other ground irrelevant to capacity and provides positive recognition of common merit as a human being and special merit as an individual; for access to resources to produce the goods and services necessary to maintain rising standards of living and comfort; for acquisition of the skills necessary to express talent and to achieve individual and community values to the fullest; for freedom to explain life, the universe, and values, to fix standards of rectitude, and to worship God or gods as may seem best; for affection, fraternity, and congenial personal relationships in groups freely chosen; for, in sum, a security which includes not only freedom from violence and threats of violence but also full opportunity to preserve and increase all values by peaceful, noncoercive procedures

Judicial Jurisdiction: From a Contacts to an Interest Analysis

This Article examines whether the courts should shift their focus to a policy or interest analysis in judicial jurisdiction cases. The Article initially identifies some of the theoretical inadequacies of, and practical difficulties with, the Supreme Court\u27s purposefully availing/minimum contacts approach to jurisdictional problems. The Article then outlines an alternative approach that employs a comprehensive form of interest analysis. After setting forth this proposed framework, the Article proceeds to examine Supreme Court decisions since International Shoe from the standpoint of the outcomes that an interest analysis approach might produce. Finally, the Article appraises these varying results and recommends that the courts employ an approach that more realistically relates to people\u27s everyday activities and more accurately reflects contemporary goals and policies
