Abstract: Polymer modified unsaturated polyester or polyesteramide resins are prepared by reacting under polymerization conditions ethylenically unsaturated polycarboxylic acids or anhydrides with water, polyol or mixtures of polyols and polyamines, and a hydrocarbon mixture comprising esterifiable hydrocarbons such as dicylopentadiene, ethylenically unsaturated aromatic hydrocarbons such as styrene or polymerized derivatives thereof, and non-reactive hydrocarbons. The polyester or polyesteramide resins have improved properties such as reduced shrinkage upon curing. When these resins are mixed with an aggregate mixture such as gravel, sand, and silica flour, polymer concrete composition is obtained. The polymer concrete compositions of the present invention have high mechanical strength and excellent compressive bond strength to both wet and dry concrete surfaces.

Abstract: A guided wave communication system or network includes a head-end unit (15) which is coupled to one end of a bus-like wave guiding means (13, 16). Separate directional couplers (14,17) are disposed along the wave guiding means to couple lightwave or microwave signals either (a) into the bus-like wave guiding means (13) from separate transmitters (11), or (b) from a bus-like wave guiding means (16) to separate receivers (12). The directional couplers disposed along a guiding means each have a separate coupling coefficient which is optimized to only couple enough of the lightwave or microwave energy onto or from the associated guiding means so that either (a) the head-end unit receives a minimal signal power level from each transmitter or (b) the receivers receive a minimal signal power level from the head-end unit, respectively, to provide a predetermined bit error rate regardless of their distance from the head-end unit along the associated waveguiding means.

Abstract: An error correction method for successively correcting burst errors which may occur in product-coded data while the data is successively transmitted along its row (or column) direction. 1-symbol errors are detected and corrected by a C₂ parity provided to correct data errors of the product-coded data in its column (or row) direction, the C₂ parity being capable of detecting and correcting 1-symbol errors and effecting an erasure correction on up to 2-symbol errors. When it is detected that a burst error has occurred, which cannot be corrected by a C₁ parity provided to correct data errors in the row (or column) direction, and such burst error extends over 3 rows (or columns) (i-1,i,i+1), inherent 2-symbol errors within such burst error are detected from 3-symbol errors which are located in columns (or rows) before and after the columns (or rows) at which 1-symbol errors have been detected and corrected by the C₂ parity with reference to detection information of the burst error detected by the C₁ parity. Erasure correction is then effected on such 2-symbol errors thus detected.

Abstract: This invention provides articles and methods for surface protection which comprises a layer of a gel material having a cone penetration of about 100 to about 350 (10 -1  mm) and an ultimate elongation of at least 100% and a covering layer of a flexible material which is flexible when installed on the surface to be protected and is hardenable or curable so that after installation the covering layer hardens to hold the gel layer in position and protect the gel layer from mechanical and other environmental conditions. This invention is particularly suitable for providing surface protection for underwater structures by applying the gel layer to displace the water from the surface which is underwater and providing a water curable covering layer which, after being applied to the surface, cures underwater to provide the required mechanical protection for the gel layer.

Abstract: To separate minerals, they are made up into a slurry A applied to a hollow tapered cylinder 30l spinning on its axis to generate l0g centrifugal force. 
     The cylinder 30l is also subjected to axial vibration at 5 to l0Hz. The cylinder widens at a half-angle of l°, and its axis is inclined at 2° upwardly in the direction of widening. 
     A film of slurry is held centrifugally to the internal surface of the cylinder and kept in suspension by the vibration. The denser (i.e. higher specific gravity) particles in the slurry tend to move preferentially radially outwardly (centrifugally) and to move downwardly in the boundary layer (under Earth's gravity). The action of the washing water B is to displace waste accidentally entrained with the higher-specific-gravity-particles. 
     The valuable higher-specific-gravity particles overflow downwardly continuously at C and are collected. The washing water and lower-specific-gravity waste particles overflow upwardly over the top edge of the cylinder at D and are discarded.

Abstract: A static monitoring system for use with an electronic manufacturing work area, typically a conventional work bench (l0) having an electrical conducting strap (l6) for connecting the operator's wrist to earth ground, and including a circuit for indicating when there is an earth ground connection and circuitry for indicating when an electrostatically charged object, such as another human, approaches the work station. An antenna (l8) is positioned at the work station spaced from the working surface (ll) and from the operator, with the antenna connected as an input to an amplifier circuit (50) which measures the change in electrostatic field strength and hence the approach of a charged object, with an indicator (l3) providing a visual or audible alarm or both. An oscillator (5l) provides an AC signal to each input of a differential amplifier, with one input connected to circuit ground through a capacitor (70) and the other input connected to a wrist strap or the like on the operator. Phase difference at the amplifier inputs is detected as a measure of the capacitance to ground at the wrist strap thereby indicating appropriate use of the wrist strap.

Abstract: A light-liquid separator has an inlet for a light liquid/heavy liquid mixture, a separator chamber for separating the mixture, a heavy-liquid discharge leading into an outflow and an automatic closure for the heavy-liquid outflow, which closes when the heavy-liquid level in the separator chamber falls below a predetermined level. The separator chamber has, in its lower region, an additional heavy-liquid outflow which is always open and which leads into a heavy-liquid chamber which is separate from the separator chamber and is provided with an overflow leading to the outflow. This prevents light liquid from being forced out of the separator chamber into the soil surrounding the separator in the event of large inflows and a closed automatic closure. <IMAGE>

Title: Radiation detector arrangements and methods
Inventor: JACKSON JOHN
IPC: G01J1/02
Filed: 1988-07-18
Abstract: Infrared, mm-wave or other radiation (100) is detected with at least one detector element in the form of a temperature-sensitive resistor (1) having a high positive temperature coefficient, e.g. 100 micro-ohm.cm.K⁻¹. A sufficiently high voltage V is applied across the resistor (1) by means of a circuit (Vb,T1) so that, in accordance with the invention, the resistor (1) passes a sufficient current (I) as to raise its temperature by Joule heating to a position at which a further increase in its temperature in response to incident radiation (100) reduces the Joule heating by reducing the current (I), thereby stabilizing the temperature of the resistor (1). This varying current (I) through the resistor (1) is measured (e.g. as a voltage V′ by means of a transconductance amplifier A) to provide a signal indicative of the power of the incident radiation (100). The change in the Joule heating produced by a change in the temperature of the resistor (1) at this position is larger (e.g. more than 10 times larger) than a change in power of the incident radiation (100) required to produce that same change in temperature of the resistor (1) in the absence of any change in Joule heating. As a result of this internal stabilization of its temperature due to the changes in Joule heating, the detector element (1) has a short time constant for response, and thermal cross-talk problems do not arise for an array of the detector elements (1) sharing a common body of the resistance material. The resistance material may be, e.g., a semiconducting barium titanate operated around or above ambient temperature, or an oxygen-deficient mixed oxide of barium, copper and yttrium which is superconducting when cooled below its high positive temperature coefficient. The resistor(s) may be mounted on a semiconductor circuit, possibly on a cryogenic cooler.
