Appl. No.:

6/316507

International Classification:

G01G 316

US Classification:

73580

Abstract:

An apparatus for measuring the precise sample mass and corresponding sample weight, being tolerant of and relatively insensitive to unwanted background environmental forces, while functioning independently of the force of gravity, uses a vibratory method and a feedback means to monitor and to sustain the sample mass in oscillation at the mechanical resonant frequency of the system in which the sample mass is introduced. The sample mass is forced to oscillate continuously by electromagnetic action, whereby the resultant motion is transmitted by springs and a transmission structure to supporting piezoelectric transducers. These transducers generate an output voltage signal representative of the sample pan's motion, that is amplified and returned to an electromagnetic drive coil in order to sustain oscillation and maintain the closed-loop nature of this system. These oscillations are monitored and the associated frequency measurements used in calculating the sample mass. A microprocessor is employed to solve a series of complex equations for calibration parameters which dynamically describe not only system mass but also system damping and spring constant while monitoring environmental variables such as temperature to correct the calculations for their effects.

International Classification:

G21C 330

US Classification:

376434

Abstract:

A nuclear fuel assembly includes and upper yoke, a base, an elongated, outer flow channel disposed substantially along the entire length of the fuel assembly and an elongated, internal, central water cross, formed by four, elongated metal angles, that divides the nuclear fuel assembly into four, separate, elongated fuel sections and that provides a centrally disposed path for the flow of subcooled neutron moderator along the length of the fuel assembly. A separate fuel bundle is located in each of the four fuel sections and includes an upper tie plate, a lower tie plate and a plurality of elongated fuel rods disposed therebetween. Preferably, each upper tie plate is formed from a plurality of interconnected thin metal bars and includes an elongated, axially extending pin that is received by the upper yoke of the fuel assembly for restraining lateral motion of the fuel bundle while permitting axial movement of the fuel bundle with respect to the outer flow channel. The outer flow channel is fixedly secured at its opposite longitudinal ends to the upper yoke and to the base to permit the fuel assembly to be lifted and handled in a vertical position without placing lifting loads or stresses on the fuel rods. The yoke, removably attached at the upper end of the fuel assembly to four structural ribs secured to the inner walls of the outer flow channel, includes, as integrally formed components, a lifting bail or handle, laterally extending bumpers, a mounting post for a spring assembly, four elongated apertures for receiving with a slip fit the axially extending pins mounted on the upper tie plates and slots for receiving the structural ribs secured to the outer flow channel.

International Classification:

B61K 702

US Classification:

104 262

Abstract:

A railcar retarder assembly for use in a railroad trackwork such as a railcar classification yard is provided with a fixed base plate, a vertically-oriented pivot shaft secured to the base plate, an elongated and curved cam member mounted on the pivot shaft, and a horizontally-oriented hydraulic subsystem piston element that induces reaction hydraulic damping forces which are transmitted horizontally to the wheel flanges of a passing railcar to thereby reduce the rolling velocity of the railcar.

International Classification:

G03B 2772

US Classification:

355 71

Abstract:

The image dot gain that normally occurs in a printing press is controllably simulated as a separate step in the process of producing accurate color proofs. The simulation is attained by placing a diffuser plate between a high-intensity light source and a color-separated image master along with its corresponding image receptor. By varying the position of the diffuser plate the percentage of image dot gain is accurately controlled as an independent variable without the need to alter the exposure time.

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G21C 700

US Classification:

376218

Abstract:

The fissile inventory required in operating a negative power coefficient nuclear reactor in an electric power generating system is reduced by cycling the load imposed on the system when 100% power can no longer be maintained at equilibrium due to xenon poisoning in order to induce an oscillation in the xenon concentration which is in antiphase wtih the power requirements so that 100% power can be maintained at least during part of the day. The load can be progressively reduced by a preset amount each night or a xenon suppression controller which forecasts the xenon reactivity at the time selected for a return to full power as a function reactor history, current reactor flux and an arbitrary load schedule can be used to determine the maximum reduced power level that will permit operation at full power at the selected time.

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H04N 718

US Classification:

358107

Abstract:

The invention projects a known geometry light source onto the surface of an object. A camera with a known distance and angular orientation with respect to the light source is used to capture the light source image on the object. The normal to the surface of the object is determined from the known size of the projected image, the angles of the intersecting lines in the projected image and the corresponding values in the received image. If a hole is to be located, the image projected is a cross and the center of the hole is determined by finding the end points of image line segments which correspond to hole edges. The center and surface normal define the location and orientation of the hole. The surface normal and the center of the hole are transformed into a robot coordinate system and a robot can be commanded to insert a bolt into the hole based on the values. The system can be used to map and measure a surface contour by determining normals and intersection points along the contour, calculating the distances between intersection points and summing these distances.
