Abstract: A process for reducing a picture,by determining monochrome data of converted picture pixels according to logical calculations based on monochrome data of original picture pixels by using divisional regions of a picture area according to a reduction rate, 
includes the steps of: successively receiving monochrome data of original picture pixels in the vicinity of a converted picture pixel; producing data of a line susceptible to disappearance, such data being necessary for detecting pixels along a line in the converted picture which could disappear from the converted picture due to picture conversion; discrimi­nating regions in which the converted picture pixels are located; calculating monochrome data of a converted picture pixel based on the generated data of a line susceptible to disappearance, data of discrimination of regions in which the converted picture pixels are located, and monochrome data of the original picture pixels; and producing a signal indicating the monochrome data of the converted picture pixel according to the calculation of monochrome data of the converted picture pixel, thereby to avoid disappearance of fine lines in the course of the reduction process.

Abstract: Measurements of the permittivity of samples over a very wide frequency range and a wide temperature range have previously involved such problems as changing parts of the measuring equipment in different regions of the frequency range, substituting one of the components of a bridge used as part of the equipment to obtain bridge balance, and limited permittivity resolution. The present invention employs a capacitance bridge formed by a sample (C₁,R₁) held between electrodes, a series capacitor C₂ and a detector comprising a high input impedance amplifier 11 and correlators 25. The bridge is balanced by applying voltages of known relative amplitude and phase constructed from outputs having relative phases of 0°, 90° and 180° of two phase-locked oscillators 13 and 14. The voltages are constructed using phase shifters 17, 20, attenuators 19, 21 and summer-driver circuits 12, 22. At low frequencies the applied voltages are obtained from a waveform synthesizer 15. In order to allow for any inaccuracies in the amplitude and phase of the applied voltages, a reference bridge is provided which comprises two capacitors 26, 27 connected in series and a detector which includes a high input impedance amplifier 28, connected between the junction of the capacitors and a common terminal.

Abstract: A corrosion product monitoring system and method are described using recirculation loop including a sample line, a particulate collection vessel, a recircu­lating pump, a microporous membrane "cross-flow" filter, and valves to control the flow rate and pressure of a sample fluid taken from the secondary fluid system of a nuclear power plant. The related method includes the steps of: taking a sample from the fluid system; introducing the sample to a recirculation loop having an initial system volume; separating non-soluble particulates from soluble contaminants; suspending the solid particu­lates; collecting the solid particulates in a particulate collection vessel; and determining a corrosion concentra­tion factor from the total sample volume divided by the initial system volume.

Abstract: Hot melt adhesives, useful for both glue-pot and glue-gun applications, are formulated so that they can be applied at temperatures no higher than 280° F. and preferably at temperatures of at most 250°F. The adhesive compositions have a heat resistance of at least 125°F. and are readily shaped into glue sticks for use in glue guns. The adhesive for the hot-melt adhesive compositions is suitably compounded with tackifying resin and/or wax. The resulting composition has a sharp viscosity profile, which is readily achieved, e.g., by using a high melt index adhesive polymer as an essential component.

Abstract: A biconic optical fiber connector (20) comprising two plugs (24-24) each having truncated conically shaped end portions (30-30) for terminating optical fibers to be connected and a sleeve (66) in which the plug end portions are received is provided with an attenuator (70) which results in low reflected power. The attenuator comprises a plate-like element which is disposed between the plug end portions. Advantageously, the plugs are seated in the sleeve and the thickness and mounting of the attenuator cooperate to cause the plug ends to engage the attenuator when the plugs are seated in the sleeve cavities. Also, the attenuator is supported within the sleeve so that it is capable of slight movement in a direction parallel to a longitudinal axis (91) of the sleeve to self-adjust, if necessary, as the plug end portions are inserted and become seated in the sleeve.

Abstract: This arrangement contains two digital pulse-duration modulators having limited resolution. The first digital pulse duration modulator supplies a first periodic pulse sequence which is pulse-duration-modulated with the quantisation value of the input variable, corresponding to the limited resolution, neglecting the quantisation remainder. The second pulse duration modulator supplies a second periodic pulse sequence which is pulse-duration-modulated with the sum of the quantisation value corresponding to the limited resolution and the quantisation remainder multiplied by a predetermined factor. A switch-over arrangement alternately switches through the pulses of the two pulse sequences to an averaging circuit in such a manner that the ratio of the number of pulses of the second pulse sequence switched through to the total number of pulses switched through is equal to the inverse value of the predetermined factor. The averaging circuit forms the direct-signal average of the pulses switched through which results in an increased resolution in comparison with the limited resolution of the digital pulse-duration modulators.
