Patent number: 5261021Abstract: A cable, which may be a fiber optic cable, includes a plurality of conductors which are twisted together. A tape with a layer of superabsorbent powder thereon, is wrapped around the conductors. A sheath is formed around the outside of the tape. If a leak should occur, the superabsorbent powder absorbs moisture and expands to block further entry of moisture into the cable. The tape is formed by applying a layer of adhesive to a strip of flexible material. The adhesive is advantageously applied in a helical pattern which is spaced from longitudinal edges of the tape. The superabsorbent powder is then applied to the adhesive. A suction head removes excess superabsorbent powder from the tape. The tape is then wrapped around the conductors of the cable. The adhesive may be a sealant material which is applied to the conductors before they are wrapped with the tape.Type: GrantFiled: April 10, 1992Date of Patent: November 9, 1993Assignee: Nordson CorporationInventors: Joseph Pasta, Richard C. Smith, Jeffrey W. Budd

Patent number: 4881247Abstract: Disclosed is a method and apparatus for measuring the burnup of nuclear fuel. A curve giving the calculated relationship between the fast neutron emission rate and the burnup of fuel is prepared. The fast neutron counting rate from a sample of nuclear fuel of known burnup is measured and the proportionality ratio between that measurement and the fast neutron emission given by the curve for the same burnup is determined. The fast neutron counting rate of nuclear fuel of unknown burnup is then measured and multiplied by the proportionality ratio to determine the fast neutron emission rate, from which the unknown burnup is then determined by means of the curve.Type: GrantFiled: March 16, 1989Date of Patent: November 14, 1989Assignee: Westinghouse Electric Corp.Inventors: Richard C.

Patent number: 4632473Abstract: An improved cabinet assembly for quick and easy assembly into various configurations. The assembly is characterized in one embodiment, by a unique joint where three framework members meet. A vertical post is equipped with vertically spaced slots. A first crossbar has prongs at one end which are snugly received in the slots, and, upon vertical movement of the crossbar, lock the crossbar to the post. A second crossbar joins the first crossbar and vertical post at mutually perpendicular angles, and is equipped with two pins which are snugly received in holes in the post. When both crossbars are in position, a bolt is inserted through the post and into the end of the second crossbar where it is secured. The bolt engages an edge of one of the prongs of the first crossbar, preventing vertical movement of the crossbar to retain it in the locked position. In another embodiment, the assembly is characterized by a drawer slide which has prongs at each end receivable in the facing slots of two parallel vertical posts.Type: GrantFiled: October 24, 1983Date of Patent: December 30, 1986Assignee: R.

Patent number: 4280048Abstract: A neutron activation probe comprises a pulsed neutron source in series with a plurality of delayed neutron detectors for measuring radioactivity in a well borehole. The neutron source emits neutrons which produce fission in uranium in the ore body and the delayed neutron detectors measure the delayed neutrons produced from such fission while the probe is moved through the borehole. The signal from each neutron detector is delayed in time so that the activity measured by each neutron detector from a particular ore zone may be added thereby increasing the accuracy of the reading corresponding to that ore zone.Type: GrantFiled: June 7, 1979Date of Patent: July 21, 1981Assignee: Wyoming Mineral CorporationInventor: Richard C.

Patent number: 4186303Abstract: Alpha particles emitted from radon 220, a daughter product formed from the decay of thorium, are prevented from reaching an alpha particle detector by enclosing the detector in a volume into which alpha-emitting radioactive gases can only enter through a semipermeable membrane at least about 10 mg/cm.sup.2 in thickness. The enclosed volume must be between 30 and 2000 cm.sup.3 and the (AP)/(VL) ratio must be between 10.sup.-7 and 10.sup.-5. Also, the detector must be positioned so as to expose it to gas from the membrane for a distance of at least 2 cm through a solid angle of at least one steradian.Type: GrantFiled: January 12, 1978Date of Patent: January 29, 1980Assignee: Westinghouse Electric Corp.Inventors: Richard C.

Patent number: 4180728Abstract: A neutron activation probe comprises a pulsed neutron source in series with a plurality of delayed neutron detectors for measuring radioactivity in a well borehole together with a NaI (T1) counter for measuring the high energy 2.62 MeV gamma line from thorium. The neutron source emits neutrons which produce fission in uranium and thorium in the ore body and the delayed neutron detectors measure the delayed neutrons produced from such fission while the NaI (Tl) counter measures the 2.62 MeV gamma line from the undisturbed thorium in the ore body. The signal from the NaI (T1) counter is processed and subtracted from the signal from the delayed neutron detectors with the result being indicative of the amount of uranium present in the ore body.Type: GrantFiled: April 11, 1978Date of Patent: December 25, 1979Assignee: Westinghouse Electric Corp.Inventors: Norman P. Goldstein, Richard C. Smith

Patent number: 4158769Abstract: The content of uranium, in a solution, as extracted from uranium ore by a solution mining technique for example, is determined by measuring the intensity of selected gamma or X radiation emitted by the solution. The gamma or X radiation is preferably derived from the thorium-234 daughter of uranium 238. The radiation from the solution impinges on a scintillator after being passed successively through K-edge filter foils of an alloy of ytterbium (e.g. with tin), an alloy of lutecium (e.g. with tin), and an alloy of hafnium (e.g. with zirconium). The resulting scintillation counts of the scintillator with the filter foils are arithmetically processed so that the scintillation derived from the thorium-234 63 KeV line is isolated. This scintillation is evaluated as a measure of the uranium content. To assure that the uranium thorium conversion has reached a stable state, the measurement should be made about three months after the uranium solution is produced.Type: GrantFiled: October 20, 1977Date of Patent: June 19, 1979Assignee: Westinghouse Electric Corp.Inventor: Richard C.
