TL;DR: It has been adequately demonstrated that computer graphics systems need not require the dedication of a large scale computer for their operation, and the requirement is basically to obtain a real time response for the display console operator, while at the same time minimizing the overhead imposed on the central computer facilities.
Abstract: It has been adequately demonstrated that computer graphics systems need not require the dedication of a large scale computer for their operation. Computer graphics has followed the trends of computing in general, where remote access, time sharing, and multiprogramming have become the key phrases. The problems involved in providing a remotely accessed, interactive computer graphics system are more formidable than for a dedicated system, or even than for a local time shared system. The requirement is basically to obtain a real time response for the display console operator, while at the same time minimizing the overhead imposed on the central computer facilities. Also present, of course, are the classic graphical problems such as that of providing refresh data for cathode ray tube displays, and of relating the appearances of a picture on the tube face to its description in the data structure.

TL;DR: In this article, a training device for runners is provided wherein an elongated framework is positioned above the ground at a height lower than the normal height of the runner so that an extended overhead obstruction is provided.
Abstract: A training device for runners is provided wherein an elongated framework is positioned above the ground at a height lower than the normal height of the runner so that an extended overhead obstruction is provided. The framework includes crossmembers at spaced intervals and a plurality of resilient crosslines at spaced intervals different from said crossmembers with the latter being at a lower position so that a multilevel obstruction is provided to simulate spaced obstacles along the chute. The framework is supported by upright U-shaped stands at each end of the chute that also serve as indicating devices as to the relative position of the overhead obstruction. Further, adjusting means is provided to allow varying the height of the framework for different exercises and different height runners.

TL;DR: In this paper, the authors propose a container for overhead visual projectUALS that simplifies the storage and use of projectUals by enabling them to be stored VERTICALLY on a SHELF or in a file drawer.
Abstract: A CONTAINER FOR OVERHEAD VISUAL PROJECTUALS THAT SIMPLIFIES THE STORAGE AND USE OF PROJECTUALS BY ENABLYING THE CONTAINER TO BE STORED VERTICALLY ON A SHELF OR IN A FILE DRAWER THROUGH THE UTILIZATION OF A SHELF-BACK.
