Solar Brayton engine/alternator set

Work on the Mod O solar Brayton engine/alternator set is redirected to utilize solarized components of the automotive advanced gas turbine (AGT). The new configuration is referred to as the Mod I. Commercialization of solar Brayton engines thus should be enhanced not only by relating the design to an engine expected to reach the high quantity, low cost production rates associated with the automotive market, but also by the potential the AGT components provide for growth of efficiency and power rating. This growth would be achieved through use of ceramics in later versions making operation possible at temperatures up to 2500 F. The longer program duration and higher cost of the Mod I is considered

A hybrid Brayton engine concept

A first generation open cycle Brayton engine concept for use in full scale solar module testing was defined. The concept extended to include solar/fossil hybrid capability. The combustion system defined for hybrid operation consists of a wide range combustor liner, a single airblast atomizer, an ignitor and a high-voltage ignition unit. Wide range combustor operation would be achieved through combining pilot and primary zones. The hybrid control mode and the solar only control mode are both based on the concept of maintaining constant turbine inlet temperature and varying the engine speed for part-power operation. In addition, the hybrid control concept will allow the operator to set a minimum thermal power input to the engine by setting a corresponding minimum engine speed. When the solar thermal power input falls below this minimum, fossil fuel would be utilized to augment the solar thermal power input

Double window viewing chamber assembly

A viewing chamber which permits observation of a sample retained therein includes a pair of double window assemblies mounted in opposed openings in the walls thereof so that a light beam can directly enter and exit from the chamber. A flexible mounting arrangement for the outer windows of the window assemblies enables the windows to be brought into proper alignment. An electrical heating arrangement prevents fogging of the outer windows whereas desiccated air in the volume between the outer and inner windows prevents fogging of the latter

The Legal Persona: An Essay on the Professional Mask

The legal profession offers little opportunity for the practitioner to analyze the fundamental constructs underlying the legal system or the dynamics of the lawyering process. Jurisprudence and legal education traditionally have emphasized the external aspects of law, implying that man is a rational decisionmaker who freely controls his life and shapes societal institutions., This approach is unrealistic because it neglects the psychological dimension of man and the complexity of man\u27s behavior. Jurisprudential scholars and legal educators should recognize that a growing body of sophisticated literature in linguistics and anthropology as well as social psychology and psychiatry is also relevant to the study of the lawyer in society. This essay adopts a socio-psychological frame of reference and explores the images and guises of the lawyer as a professional in an attempt to add a new perspective to contemporary philosophy of lawyering

Book Review

Shaffer suggests a new paradigm for law practice that is not based on rigid control of clients in an impersonal attorney-client relationship. He argues forcefully that disregard for the client\u27s emotions ignores important facts that can be used in the law office and the legal process. Shaffer\u27s work suggests the possibility of gaining personal satisfaction and of providing more adequate legal services by actively counseling and understanding clients. Such a humanistic approach to the practice of law can be rooted only in an awareness of the psychological and social defenses erected against both the attorney\u27s clients and the attorney\u27s impact on society. Attorneys must learn to deal with the human emotions and feelings of clients primarily through managing their own greatest fear-the fear of knowing who they truly are. Shaffer\u27s prescription for law practice allows attorneys to ground and center themselves in authentic human experience through their work with clients. Legal Interviewing and Counseling offers a preliminary blueprint for that process
