Title: Constant sensitivity superheated droplet radiation detector/dosimeter
Inventor: BONIFACE HUGH
IPC: G01T5/04
Filed: 1989-05-18
Granted: 1993-04-20
Abstract: TITLE     Constant Sensitivity Superheated Droplet Radiation Detector/Dosimeter INVENTORS          Hugh Boniface Robert Noulty John Jevcak Harry Ing ABSTRACT OF THE DISCLOSURE      Radiation detectors and dosimeters having superheated droplets of detector liquid as the radiation-sensitive component have been found to have significant variation in sensitivity with changes in operating temper-ature.  In order to provide a more constant sensitivity, a self-regulating pressure control means has been developed which will alter the pressure on the droplet-containing medium to compensate for changes in operating temperature.          The pressure control means is for instance a mechanical system selected from a pressure-multiplying piston or bellows assembly pressurized by a volatile liquid, and a spring-loaded elastic diaphragm assembly.  This pressure control means is designed to maintain a constant degree of superheat of the detector liquid in activated detectors.

Title: Structural stabilization system
Inventor: GARZA-TAMEZ FEDERICO
IPC: F16F15/02
Filed: 1989-07-14
Granted: 1993-08-03
Abstract: ABSTRACT      A structure stabilization system for protecting structures from effects of seismic disturbances.  Plural bases of a base isolation system support, through flexible suspension elements, corresponding, plural vertical support columns.  Corresponding adjustment mechanisms on each base provide for adjusting all support elements to a common elevation.  A gripper mechanism in each base is selectively, axially adjusting to establish substantially identical, effective free suspension lengths and common harmonic characteristics of all suspension elements.  A releasable interlock subsystem interlocks the structure to the foundation to render it stable against minor forces, such as produced by wind, and automatically releases the structure to permit same to float in support by the base isolation system in response to forces exceeding a predetermined level.  A damping subsystem comprises plural dampers connected in symmetrically located positions between the structure and the foundation and arranged, at a minimum, as oppositely disposed, mutually orthogonal pairs, the associated dampers of each pair being hydraulically interconnected and mechanically connected between the structure and its associated foundation in inverse relationship.

Title: Method for three-dimensional clip checking for computer graphics
Inventor: PRIEM CURTIS
IPC: G06T15/30
Filed: 1989-09-15
Granted: 1992-06-02
Abstract: ABSTRACT OF THE INVENTION A method for clip checking three dimensional images for display on a computer display system is disclosed. The display system includes a computer having a central processing unit(CPU) coupled to a memory and a cathode ray tube (CRT) display. The method of the present invention includes inputting a plurality of points comprising an image to be displayed, wherein each of the points is described by X, Y, Z and W world coordinates. The points are stored in the memory coupled to the CPU. The CPU executes a viewing algorithm which transforms the world coordinates for each point into view reference coordinates. The view reference coordinates have an origin at the viewpoint of the user with the Z axis pointed outward in the direction of the display screen. Each of the points of the image are described by clipping bits X Right, X Left, Y Top, Y Bottom, Z Back, and Z Front. The view reference coordinate system of the present invention permits the user to selectively enable/disable clipping quadrants in X, Y, Z and W space. The present invention determines the value of the clipping bits for all of the points (vertices) comprising the image. Using predefined combinational logic, the present invention evaluates the clipping bits and determines if the image is visible, hidden, or if it intersects at least one clipping plane. The method of the present invention provides an efficient means for determining if a three dimensional image is to be displayed on a computer display system.

Filed: 1990-04-18
Granted: 1995-01-03
Abstract: In a film cassette, a film spool comprises a spool core supported for rotation in an unwinding direction to thrust a leader section of a film roll coiled about the spool core to the exterior of the cassette and in a winding direction to return the leader to the interior of the cassette, and a pair of flanges positioned along the spool core to overlie opposite sides of the film roll to radially confine the film roll within skirted peripheries of the flanges.  The flanges have respective central openings through which the spool core coaxially extends to normally permit the flanges and the spool core to be independently rotated in the two directions.  According to the invention, engagement hooks are rotatably fixed to the spool core for initial rotation with the spool core relative to the flanges in the unwinding direction, for movement into engagement with at least one of the flanges to make the flange rotate in unity with the spool core when the spool core is rotated further in the unwinding direction, to improve the ability of the film spool to thrust the leader from the cassette, and in the film winding direction, for movement out of engagement with the flange to permit the flange to be independently rotated when the spool core is rotated further in the winding direction, to substantially ensure the leader can be rewound within the skirted periphery of the flange.
