Title: Blind fastener and method of making
Inventor: PRATT JOHN D
IPC: F16B19/10
Filed: 1990-08-22
Abstract: A blind fastener comprises a fastener body (12), a stem (14) and a shaped shear ring wire (18). The shear ring (18) in one embodiment is disposed in an annular groove (36) disposed intermediate the ends of a neck of the stem (14). When the fastener is installed, a bulbing portion (44) of the shear ring (18) upsets the tail end of the fastener and then shears at a predetermined load. An anchor portion (42) of the shear ring (18) travels through the fastener body, with the stem neck radially expanding the fastener to fill the hole within the workpieces (24) being secured together.  A  lock ring groove (34) is formed in the stem midsection of smaller diameter at the intersections of the stem neck and midsection. In another embodiment, the shear ring (18) is positioned at the intersection so that the shear ring anchor portion (42) engages the rear of a lock ring positioned in said lock ring groove (36).

Title: Apparatus and method for transmitted-light and reflected-light imaging
Inventor: DIXON ARTHUR E
IPC: G02B21/00
Filed: 1991-06-28
Abstract: ABSTRACT:    A new scanning optical microscope or mapping system for transmission, reflection and luminescence imaging is disclosed. A transmission arm collects light transmitted through the specimen and injects it back into the optical path of the microscope parallel with and coaxial with the reflected light beam returning from the specimen, so both transmitted and reflected light beams are descanned by the same scan optics on their way back to the same detector.  Since light travels around the transmission arm in both directions, this microscope forms images of the specimen from either the top or the bottom and in either reflected light or transmitted light, and all four of these imaging modes can be selected separately.  Embodiments for use in fluorescence and photoluminescence imaging are also disclosed.

Title: Automatic tester and calibrator for instruments or fluid meters
Inventor: TUOT NEAT
IPC: G01F25/00
Filed: 1993-05-28
Abstract: ABSTRACT OF THE DISCLOSURE            A mechanical tester for instrument for fluid meters, commonly known as an instrument tester, a motorized base, a turntable, or an instrument drive simulator, consists of an electric motor, a set of pulleys and a preset counter. Its usefulness is limited to causing the instrument driving mechanism, thus the instrument under  test,  to  travel  a  predetermined  number  of revolutions and in a predetermined direction. It has no provision for receiving and making use of the feedbacks directly from the instrument under test. The automatic instrument tester and calibrator provides for  the  monitor  of  events  and  conditions  which directly or indirectly affect the accuracy of the instrument under test thus reducing the elements of uncertainty in the instrument calibrating process. The automatic instrument tester and calibrator further provides for the computation of the instrument's error and for storing the test data for further processing and retrieval thus reducing error, calibrating time, and thus reducing operating cost.

Filed: 1991-10-21
Abstract: ABSTRACT         The present invention relates to an apparatus for and a method of generating heat by utilizing the Pons-Fleischmann effect.  In a conventional apparatus of this kind, an anode and a cathode are dipped in an electrolyte, and an external power source is used for causing a current to flow between the anode and the cathode.  In the present invention, a relation among the anode, the electrolyte and the cathode is made similar to that in a primary cell, and thus excess heat based upon the Pons-Fleischmann effect can be generated without using the external power source.  Accordingly, the number of ports making up the apparatus is reduced.
