摘要： The data communication system includes a first control device, a second data device and a data link, including a first transmission link and a second transmission link, between the second data device and the first control device. A data driver enables data transmission from the second data device to the first control device across the data link, and a differential controller is adapted to generate a voltage differential between the first transmission link and the second transmission link. A detector detects differences in voltage levels between the first transmission link and the second transmission link. The data communication system enables bi-directional communication between integrated circuit devices over a serial communication link avoiding the necessity for clock, chip enable and control connections on the data device and is particularly useful for communication between an image sensor and coprocessor.

摘要： In a bulk material analyzer in which bulk material is received in an activation region between a pair of neutron sources laterally disposed on one side of the activation region for emitting neutrons for bombarding the bulk material within the activation region to cause gamma-rays to be emitted from the bombarded bulk material and a pair of gamma-ray detectors laterally disposed on an opposite side of the activation region for detecting gamma-rays emitted from the bulk material, and in which a neutron moderator is disposed between the neutron sources and the activation region for reducing the velocity of the emitted neutrons such that the neutrons entering the activation region include thermal neutrons and faster neutrons, the uniformity of sensitivity of the bulk material analyzer to materials at different positions in a sample of the bulk material being analyzed is enhanced by controlling the proportions of thermal neutron at different positions within the sample being analyzed. A neutron absorber disposed close to the one side of the activation region reduces the proportion of thermal neutrons that enter the activation region from the one side of the activation region. A neutron reflector disposed on the opposite side of the activation region at least as close to the activation region as the gamma-ray detector(s) reflects neutrons into the activation region for bombarding bulk material within the activation region. In some embodiments, the neutron absorber and/or the neutron reflector are adjustable; and the disposition of the neutron sources also is adjustable for also adjusting the proportion of the thermal neutrons that enter the activation region from the one side of the activation region.

摘要： Echo ranging flaw detecting, characterizing and studying apparatus in which the work is scanned simultaneously by acoustic energy focused at a point from an acoustic-lens transducer and by acoustic energy focused along a line along which it is propagated from a focused-arc transducer. The acoustical echos from the lens transducer are combined with an electrical analog of an acoustical reference wave to produce an acoustical interference pattern which is reconstructed into a holographic display or hologram by a laser beam. The echos from the focused-arc transducer produce a cathode-ray tube display or are stored in a memory.

摘要： A modular assembly for a bulk material includes container modules defining at least one radiation source cavity, at least one radiation detector channel and a passageway disposed for enabling passage of the conveyor belt through an activation region; and radiation shielding material disposed within the container means. A lower primary module contains a first portion of the radiation shielding material and defines either the radiation source cavity or the radiation detector channel. An upper primary module contains a second portion of radiation shielding material and defines the other of either the radiation source cavity or the radiation detector channel. A set of replaceable side modules contain additional portions of the radiation shielding material. The lower primary module, the upper primary module and the replaceable side modules are so shaped that the passageway is delimited by placement of side modules upon the lower primary module and placement of the upper primary module upon side modules; and portions of the replaceable side modules are shaped for delimiting the sides of a trough that is contoured for accommodating passage of the conveyor belt through the activation region. Replaceable liners of neutron moderating and/or absorbing and/or reflecting material may be placed adjacent the passageway and adjacent the side modules and/or the lower module and/or the upper module for further delimiting the passageway and/or the sides of the trough. The assembly can be modified for use with large ranges of conveyor belt sizes and shapes by replacing the replaceable side modules and/or the replaceable liners.

摘要： A method for reacting a methylene-containing component such as an acrylic polymer prepared from acetoacetoxyalkyl (meth)acrylate and an alkene-containing component such as a polyfumarate, polymaleate, a polyester containing both fumarate and maleate groups or a polyacrylate comprises the reaction of a tertiary amine such as triethylene diamine and an epoxide such as a glycidyl-functional (meth)acrylic polymer in the presence of the methylene-containing component and alkene-containing component. The tertiary amine can be incorporated into the alkene-containing component such as the reaction of an unsaturated polyester with a compound having both tertiary amine and primary or secondary amine groups. The tertiary amine can be incorporated into the methylene-containing component such as an acrylic polymer derived from a tertiary amino-functional monmer and acetoacetoxyalkyl (meth)acrylate. The epoxide can be incorporated into the methylene-containing component such as an acrylic polymer obtained from glycidyl (meth)acrylate and acetoacetoxyalkyl (meth)acrylate. The epoxide can be incorporated into the alkene-containing component.

摘要： A hydroball string sensing system for a nuclear reactor that includes stainless tubes positioned to guide hydroball strings into and out of the nuclear reactor core. A sensor such as an ultrasonic transducer transmitter and receiver is positioned outside of the nuclear reactor core and adjacent to the tube. The presence of an object such a bullet member positioned at an end a hydroball string, or any one of the hydroballs interrupts the transmission of ultrasound from the transmitter to the receiver. Alternatively, if the bullet member and hydroballs include a ferritic material, either a Hall effect sensor or other magnetic field sensors such as a magnetic field rate of change sensor can be used to detect the location and position of a hydroball string. Placing two sensors along the tube with a known distance between the sensors enables the velocity of a hydroball string to be determined. This determined velocity can be used to control the flow rate of a fluid within the tube so as to control the velocity of the hydroball string.

摘要： An acoustic transducer-reflector using a single disc-shaped piezoceramic element radiating into a compound reflector for obtaining a line focus sound beam that is characteristic of focused-arc transducers that maybe used for underseas applications and for non-destructive materials testing. The single transducer emits acoustic energy into the compound reflector which reshapes a circular beam into a focused arc beam. A shadow mask or aperture stop positioned in front of the reflector assures a beam such as would be radiated from a ring source.
